    The aim of this article is to report the psychometric properties of the eight-item cognitive load scale. According to cognitive load theory, the formatting and delivery of healthcare education influences the degree to which patients and/or family members can engage their working memory systems for learning. However, despite its relevance, cognitive load has not yet been evaluated among surrogate decision makers exposed to electronic decision support for healthcare decisions. To date, no psychometric analyses of instruments evaluating cognitive load have been reported within healthcare settings. A convenience sample of 62 surrogate decision makers for critically ill patients were exposed to one of two healthcare decision support interventions were recruited from four intensive care units at a tertiary medical center in Northeast Ohio. Participants were administered a battery of psychosocial instruments and the eight-item cognitive load scale (CLS). The CLS demonstrated a bidimensional factor structure with acceptable discriminant validity and internal consistency reliability (Cronbach's α = 0.75 and 0.89). The CLS is a psychometrically sound instrument that may be used in the evaluation of decision support among surrogate decision makers of the critically ill. The authors recommend application of the cognitive load scale in the evaluation and development of healthcare education and interventions. Copyright © 2018 Elsevier Inc. All rights reserved.

    Music in Dementia Assessment Scales (MiDAS), an observational outcome measure for music therapy with people with moderate to severe dementia, was developed from qualitative data of focus groups and interviews. Expert and peer consultations were conducted at each stage of the scale development to maximize its content validity. This study aimed to evaluate the psychometric properties of MiDAS. Care home residents with dementia attended weekly group music therapy for up to ten sessions. Music therapists and care home staff were requested to complete weekly MiDAS ratings. The Quality of Life Scale (QoL-AD) was completed at three time-points. A total of 629 (staff = 306, therapist = 323) MiDAS forms were completed. The statistical analysis revealed that MiDAS has high therapist inter-rater reliability, low staff inter-rater reliability, adequate staff test-retest reliability, adequate concurrent validity, and good construct validity. High factor loadings between the five MiDAS Visual Analogue Scale (VAS) items, levels of Interest, Response, Initiation, Involvement, and Enjoyment, were found. This study indicates that MiDAS has good psychometric properties despite the small sample size. Future research with a larger sample size could provide a more in-depth psychometric evaluation, including further exploration of the underlying factors. MiDAS provides a measure of engagement with musical experience and offers insight into who is likely to benefit on other outcomes such as quality of life or reduction in psychiatric symptoms.

    Full Text Available The challenge of using exergames to promote physical activity among cancer survivors lies in the selection of the exergames that match their fitness level. There is a need for a standardized grading scheme by which to judge an exergame’s capacity to address specific physical fitness attributes with different levels of physical engagement. The study aimed to develop an Exergame Grading Scheme and preliminarily evaluate its psychometric properties. Fourteen (14 items were created from the human movement and exergame literature. The content validity index (CVI was rated by content experts with two consecutive rounds (N=5 and N=3 independently. The interrater reliability (IRR was determined by two raters who used the Exergame Grading Scheme to determine the grading score of the five exergames performed by two cancer survivors (N=10. Each item had a score of 1 for item-level CVI and 1 for k. For IRR, 9 items had rho values of 1, 1 item had 0.93, and 4 items had between 0.80 and 0.89. This valid and reliable Exergame Grading Scheme makes it possible to develop a personalized physical activity program using any type of exergame or fitness mobile application in rehabilitation practice to meet the needs of cancer survivors.

    To report the development of a tool to measure nurse's attitudes about quality improvement in their practice setting and to examine preliminary psychometric characteristics of the Quality Improvement Nursing Attitude Scale. Human factors such as nursing attitudes of complacency have been identified as root causes of sentinel events. Attitudes of nurses concerning use of Quality and Safety Education for nurse's competencies can be most challenging to teach and to change. No tool has been developed measuring attitudes of nurses concerning their role in quality improvement. A descriptive study design with preliminary psychometric evaluation was used to examine the preliminary psychometric characteristics of the Quality Improvement Nursing Attitude Scale. Registered bedside clinical nurses comprised the sample for the study (n = 57). Quantitative data were analysed using descriptive statistics and Cronbach's alpha reliability. Total score and individual item statistics were evaluated. Two open-ended items were used to collect statements about nurses' feelings regarding their experience in quality improvement efforts. Strong support for the internal consistency reliability and face validity of the Quality Improvement Nursing Attitude Scale was found. Total scale scores were high indicating nurse participants valued Quality and Safety Education for Nurse competencies in practice. However, item-level statistics indicated nurses felt powerless when other nurses deviate from care standards. Additionally, the sample indicated they did not consistently report patient safety issues and did not have a feeling of value in efforts to improve care. Findings suggested organisational culture fosters nurses' reporting safety issues and feeling valued in efforts to improve care. Participants' narrative comments and item analysis revealed the need to generate new items for the Quality Improvement Nursing Attitude Scale focused on nurses' perception of their importance in quality and

    Conclusion According to the results, the detection protocol of malingering stuttering is of good internal consistency and concurrent validity. However, considering that the sample population was not large in the present study, it can be said that this study is a preliminary evaluation to find the psychometric features of the instruments, with the aim of laying the groundwork for further studies.

    Full Text Available Cultivating empathy and prosocial attitude towards disability is a first step for university students to become the leaders of society and professions to create accessible environments and inclusive society. Gauging levels of empathy and prosocial attitude towards disability among the students is important for evaluating the adequacy of disability training and education. We developed and conducted an initial psychometric validation of a novel inventory in Japanese and English languages to assess Empathic Concern for Disability and Accessibility (ECDA in Japan and New Zealand. Preliminary psychometric evaluation indicates strong internal consistency in the Japanese sample (α = .96 and the New Zealand sample (α = .93. Exploratory factor analysis demonstrated a four-factor solution for both samples. The present study has resulted in the development of the ECDA that demonstrated initial support for internal consistency and construct validity. The ECDA may be used for the cross-cultural comparisons of disability training and education.

    2016-04-01

    The Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013) alternative model for personality disorders (PDs) introduced a new paradigm for the assessment of PDs that includes levels of personality functioning indexing the severity of personality pathology irrespective of diagnosis. In this study, we describe the development and preliminary psychometric evaluation of a newly developed brief self-report questionnaire to assess levels of personality functioning, the Level of Personality Functioning Scale-Brief Form (LPFS-BF; Bender, Morey, & Skodol, 2011). Patients (N = 240) referred to a specialized setting for the assessment and treatment of PDs completed the LPFS-BF, the Brief Symptom Inventory (BSI; Derogatis, 1975), the Severity Indices of Personality Problems (SIPP-118; Verheul et al., 2008), and were administered the Structured Clinical Interview for DSM-IV Axis I Personality Disorders (SCID-I; APA, 1994; First, Spitzer, Gibbon, & Williams, 1997) and the SCID Axis II Personality Disorders (SCID-II; First, Spitzer, Gibbon, Williams, & Benjamin, 1996). When constrained to a 2-factor oblique solution, the LPFS-BF yielded a structure that corresponded well to an interpretation of Self- and Interpersonal Functioning scales. The instrument demonstrated fair to satisfactory internal consistency and promising construct validity. The LPFS-BF constitutes a short, user-friendly instrument that provides a quick impression of the severity of personality pathology, specifically oriented to the DSM-5 model. Clearly, more research is needed to test its validity and clinical utility. (c) 2016 APA, all rights reserved).

    Adolescents and young adult (AYA) cancer survivors may have unique physical, psychological and social needs due to their cancer occurring at a critical phase of development. The aim of this study was to develop a psychometrically rigorous measure of unmet need to capture the specific needs of this group. Items were developed following a comprehensive literature review, focus groups with AYAs, and feedback from health care providers, researchers and other professionals. The measure was pilot tested with 32 AYA cancer survivors recruited through a state-based cancer registry to establish face and content validity. A main sample of 139 AYA cancer patients and survivors were recruited through seven treatment centres and invited to complete the questionnaire. To establish test-retest reliability, a sub-sample of 34 participants completed the measure a second time. Exploratory factor analysis was performed and the measure was assessed for internal consistency, discriminative validity, potential responsiveness and acceptability. The Cancer Needs Questionnaire - Young People (CNQ-YP) has established face and content validity, and acceptability. The final measure has 70 items and six factors: Treatment Environment and Care (33 items); Feelings and Relationships (14 items); Daily Life (12 items); Information and Activities (5 items); Education (3 items); and Work (3 items). All domains achieved Cronbach's alpha values greater than 0.80. Item-to-item test-retest reliability was also high, with all but four items reaching weighted kappa values above 0.60. The CNQ-YP is the first multi-dimensional measure of unmet need which has been developed specifically for AYA cancer patients and survivors. The measure displays a strong factor structure, and excellent internal consistency and test-retest reliability. However, the small sample size has implications for the reliability of the statistical analyses undertaken, particularly the exploratory factor analysis. Future studies with a

    For norm-referenced measures to be useful in social-behavioral research, investigators who develop measures face several psychometric challenges, including: (a) adequate domain specification; (b) adequate initial evidence of reliability and validity; and (c) ongoing evidence of psychometric quality. The Interpersonal Relationship Inventory (IPRI) was developed in response to gaps in measurement of social relationships, and contributed scales for reciprocity and conflict to a measure of social support. For the IPRI, the first two points were addressed during the period of instrument development. The measure now has been in use for 4 years. This article reports evidence addressing the third challenge: ongoing evidence of psychometric quality. Findings from 19 studies using the IPRI provide compelling evidence for internal consistency reliability and construct validity of the scales.

    The Structured Trauma-Related Experiences and Symptoms Screener (STRESS) is a self-report instrument for youth of age 7-18 that inventories 25 adverse childhood experiences and potentially traumatic events and assesses symptoms of post-traumatic stress disorder using the revised criteria published in the Diagnostic and Statistical Manual for Mental Disorders, fifth edition (DSM-5). The STRESS can be administered by computer such that questions are read aloud and automatic scoring and feedback are provided. Data were collected on a sample of 229 children and adolescents of age 7-17 undergoing a forensic child abuse and neglect evaluation. The purpose of the current study was to examine preliminary psychometric characteristics of the computer-administered STRESS as well as its underlying factor structure in relation to the four-factor DSM-5 model. Results provide initial support for the use of the STRESS in assessing adverse and potentially traumatic experiences and traumatic stress in children and adolescents. © The Author(s) 2015.

    2015-01-01

    The purpose of this study was to examine psychometric properties of the Perceived Value of Certification Tool© with a focus on nurse educator certification (PVCT-NE) in a sample of nurse educators. Greater understanding of faculty perceptions of certification is necessary to facilitate a strong cadre of nursing faculty; however, research around nurse educator certification is limited by a lack of reliable and valid instruments to measure such perceptions. Twenty-four nursing faculty from one university participated in the psychometric study, which involved completion of the PVCT-NE in a web-based survey format. Internal consistency reliability was excellent. Cronbach's alpha for the total PVCT-NE was .94 (.93 for the intrinsic subscale and .86 for the extrinsic subscale). A content validity index of .95 was obtained. There is preliminary evidence that the PVCT-NE is a reliable and valid instrument to measure perceived value of certification in nurse educators.

  2. A psychometric evaluation of the digital logic concept inventory

    2014-10-01

    Concept inventories hold tremendous promise for promoting the rigorous evaluation of teaching methods that might remedy common student misconceptions and promote deep learning. The measurements from concept inventories can be trusted only if the concept inventories are evaluated both by expert feedback and statistical scrutiny (psychometric evaluation). Classical Test Theory and Item Response Theory provide two psychometric frameworks for evaluating the quality of assessment tools. We discuss how these theories can be applied to assessment tools generally and then apply them to the Digital Logic Concept Inventory (DLCI). We demonstrate that the DLCI is sufficiently reliable for research purposes when used in its entirety and as a post-course assessment of students' conceptual understanding of digital logic. The DLCI can also discriminate between students across a wide range of ability levels, providing the most information about weaker students' ability levels.

    Public speaking is the most commonly reported fearful social situation. Although a number of contemporary theories emphasize the importance of cognitive processes in social anxiety, there is no instrument available to assess fearful thoughts experienced during public speaking. The Self-Statements During Public Speaking (SSPS) scale is a 10-item questionnaire consisting of two 5-item subscales, the “Positive Self-Statements” (SSPS-P) and the “Negative Self-Statements” subscale (SSPS-N). Four studies report on the development and the preliminary psychometric properties of this instrument. PMID:16763666

    The present study evaluated the psychometric properties of a novel measure of social anxiety symptoms, the Social Interaction Phobia Scale (SIPS), as a stand-alone item set, using an undergraduate sample (N=512). The 14-item SIPS has three subscales assessing Social Interaction Anxiety, Fear of Overt Evaluation, and Fear of Attracting Attention. Confirmatory factor analyses replicated the three-factor structure for the SIPS originally reported by Carleton et al. All SIPS scores demonstrated good internal consistency. The convergent validity of the SIPS was supported by strong and positive correlations between all SIPS scores and measures of social anxiety and fear of evaluation; the finding that the relationships between all SIPS scores and a social anxiety measure were stronger than relationships between all SIPS scores and measures of other constructs supported the discriminant validity of the SIPS. Results suggest that the SIPS possesses excellent psychometric properties.

    Full Text Available Introduction Assessment of episodic memory has been traditionally used to evaluate potential cognitive impairments in senior adults. Typically, episodic memory evaluation is based on personal interviews and pen-and-paper tests. This article presents the design, development and a preliminary validation of a novel digital game to assess episodic memory intended to overcome the limitations of traditional methods, such as the cost of its administration, its intrusive character, the lack of early detection capabilities, the lack of ecological validity, the learning effect and the existence of confounding factors. Materials and Methods Our proposal is based on the gamification of the California Verbal Learning Test (CVLT and it has been designed to comply with the psychometric characteristics of reliability and validity. Two qualitative focus groups and a first pilot experiment were carried out to validate the proposal. Results A more ecological, non-intrusive and better administrable tool to perform cognitive assessment was developed. Initial evidence from the focus groups and pilot experiment confirmed the developed game’s usability and offered promising results insofar its psychometric validity is concerned. Moreover, the potential of this game for the cognitive classification of senior adults was confirmed, and administration time is dramatically reduced with respect to pen-and-paper tests. Limitations Additional research is needed to improve the resolution of the game for the identification of specific cognitive impairments, as well as to achieve a complete validation of the psychometric properties of the digital game. Conclusion Initial evidence show that serious games can be used as an instrument to assess the cognitive status of senior adults, and even to predict the onset of mild cognitive impairments or Alzheimer’s disease.

    The purpose of this study was to evaluate psychometric properties of the shortened Resilience Scale (15-item version RS15) among a sample of Alzheimer's caregivers. Self-reported data were collected from 229 participants at 2 Alzheimer's caregiver conferences. RS15 principal axis factoring indicated a single-dimensional solution with all items loaded. Reliability was strong. Convergent validity for the RS15 was suggested through its correlations with stress, family support, and friend support. Odds ratios showed significant likelihoods of high resilience given low stress and high social support. The results confirmed the RS15 to be a psychometrically sound measure that can be used to appraise the efficacy of adaptability among Alzheimer's caregivers.

    2017-06-01

    Psychological inflexibility and experiential avoidance are equivalent (with somewhat different connotations) concepts and refer to an unwillingness to remain in contact with particular private events. This concept is most often measured by the Acceptance and Action Questionnaire (AAQ-II) and is strongly related to psychopathology and behavioral effectiveness. In this study, the preliminary psychometric properties of the Swedish version of the AAQ-II (Swedish Acceptance and Action Questionnaire-SAAQ) are presented. The study is done in two steps. In the first step, the 10-item version of the AAQ-II is investigated through principal component analysis (n = 147). Secondly, due to problems with the component structure, the instrument is reduced to a six-item version and its validity and internal consistency are investigated (n = 154). The six-item version shows good concurrent and convergent validity as well as satisfying internal consistency (α = .85). Furthermore, the Swedish six-item version of the AAQ-II showed one strong component. Test-retest reliability was satisfactory (r = .80; n = 228). In future research, predictive and external validity would be important to investigate in order to further ensure that the SAAQ is a useful measure for clinical research. In conclusion, the SAAQ has satisfactory psychometric properties, but more data need to be gathered to further explore the possibilities for the instruments in Swedish contexts.

    Research purpose: The objectives of this study were to investigate the internal validity (construct, discriminant and convergent validity, reliability and external validity (relationship with theoretically relevant variables, including job characteristics, home characteristics, burnout, ill health and life satisfaction of the instrument. Motivation for the study: Work-family interaction is a key topic receiving significant research attention. In order to facilitate comparison across work-family studies, the use of psychometrically sound instruments is of great importance. Research design, approach and method: A cross-sectional survey design was used for the target population of married employees with children working at a tertiary institution in the North West province (n = 366. In addition to the new instrument, job characteristics, home characteristics, burnout, ill health and life satisfaction were measured. Main findings: The results provided evidence for construct, discriminant and convergent validity, reliability and significant relations with external variables. Practical/managerial implications: The new instrument can be used by researchers and managers as a test under development to investigate the interference between work and different nonwork roles (i.e. parental role, spousal role, work role, domestic role and specific relations with antecedents (e.g. job/home characteristics and well-being (e.g. burnout, ill health and life satisfaction. Contribution/value-add: This study provides preliminary information on the psychometric properties of a new instrument that measures the interference between work and nonwork.

    Full Text Available This study aimed to develop and assess the psychometric properties of an English language measure of problematic mobile phone use. Participants were recruited from a university campus, health science center, and other public locations. The sample included 244 individuals (68.4% female aged 18–75. Results supported a unidimensional factor structure for the 20-item self-report Problematic Use of Mobile Phones (PUMP Scale. Internal consistency was excellent (α=0.94. Strong correlations (r=.76, P<.001 were found between the PUMP Scale and an existing scale of cellular phone dependency that was validated in Asia, as well as items assessing frequency and intensity of mobile phone use. Results provide preliminary support for the use of the PUMP Scale to measure problematic use of mobile phones.

    To develop and validate a self-reporting questionnaire assessing the burden of exercise therapy for patients with chronic conditions. Measurement properties of an instrument. Outpatient clinics and tertiary care hospital. Patients (N=201) with at least 1 chronic condition and performing exercise therapy. Not applicable. The dimensional structure of the questionnaire was assessed by principal component analysis. Construct validity of the instrument was assessed by exploring convergent validity with the Treatment Burden Questionnaire (TBQ) and divergent validity with pain, self-efficacy, treatment satisfaction, and health state. Reliability was assessed with the Cronbach α coefficient, a test-retest method using the intraclass correlation coefficient (ICC), and Bland-Altman plotting. A preliminary list of items was developed from semistructured interviews with 28 patients and reviewed by 2 expert physicians. Items obtained were reduced. Then a sample of 163 patients was used to measure the psychometrics of the Exercise Therapy Burden Questionnaire (ETBQ), consisting of 10 items. Principal component analysis extracted 1 dimension. The Cronbach α was .86 (.82-.89). Test-retest reliability (n=24 patients) was good with an ICC of .93 (.85-.97), and Bland-Altman analysis did not reveal a systematic trend. The ETBQ showed expected convergent validity with the TBQ (ρ=.52) and expected divergent validity with pain (ρ=.37), self-efficacy (ρ=-.34), treatment satisfaction (ρ=-.49), and perceived health state (ρ=-.28). The ETBQ is the first questionnaire assessing exercise therapy burden in patients with chronic conditions. Its psychometric properties are promising.

    Purpose The purpose of this paper is to develop and evaluate psychometrically an instrument named the Breast Size Satisfaction Scale (BSSS) to assess breast size satisfaction. Design/methodology/approach The present scale was developed using a set of 16 computer-generated 3D images of breasts to overcome some of the limitations of existing instruments. The images were presented to participants and they were asked to select the figure that most accurately depicted their actual breast size and the figure that most closely represented their ideal breast size. Breast size satisfaction was computed by subtracting the absolute value of the difference between ideal and actual perceived size from 16, such that higher values indicate greater breast size satisfaction. Findings Study 1 ( n=65 female undergraduate students) showed good test-retest reliability and study 2 ( n=1,000 Iranian women, aged 18 years and above) provided support for convergent validity using a nomological network approach. Originality/value The BSSS demonstrated good psychometric properties and thus can be used in future studies to assess breast size satisfaction among women.

    Commercial electric power generation, nuclear weapons production, the operation of naval reactors, and research and development activities produce spent nuclear fuel and high-level radioactive waste. Spent nuclear fuel and high-level radioactive waste have been accumulating at commercial reactor sites and storage facilities across the country since 1957. Spent nuclear fuel and high-level radioactive waste have been accumulating at sites now managed by U.S. Department of Energy (DOE) since the mid-1940s. The DOE has the statutory obligation to dispose of these wastes. The U.S. has studied methods for the safe storage and disposal of radioactive waste for more than 40 years. Many organizations and government agencies have participated in these studies. In the 1950s, the U.S. Atomic Energy Commission requested the National Academy of Sciences to evaluate options for land disposal of radioactive waste. The U.S. Atomic Energy Commission and its successor agencies, the Energy Research and Development Administration and the DOE, continued to analyze radioactive waste management options throughout the 1960s and 1970s. In 1979, an Interagency Review Group that included representatives of 14 federal government entities provided findings and recommendations to the President. After analyzing a range of options, disposal in a geologic repository emerged as the preferred long-term environmental solution. This consensus is reflected in the Nuclear Waste Policy Act of 1982 (NWPA). The NWPA and related statutes established the framework for addressing the issues of radioactive waste disposal and designated the roles and responsibilities of the federal government and the owners and generators of the waste

    2003-12-01

    The purpose of this study was to develop and evaluate the psychometric properties of 2 supportive leadership scales, the Charge Nurse Support Scale and the Unit Manager Support Scale, designed for long-term-care environments. These 6-item self-report scales were administered to 70 nursing staff and their internal consistency reliability, test-retest reliability, content validity, factor structure, and construct validity investigated. Content validity was established with the assistance of experts. Both scales were deemed reliable. As hypothesized, a significant relationship was found between the measure of how nursing staff related to residents and measures of charge nurses' supportive behaviours (r = .42, p = .05). Reliable and valid measures of supportive leadership could be developed for use in identifying the quality of support provided to staff in long-term-care environments.

    Hartzler, Bryan

    2015-08-01

    A paper/pencil instrument, adapted from Miller and colleagues' (1991) Helpful Responses Questionnaire (HRQ), was developed to assess clinician skill with core communicative aspects involved in delivering contingency management (CM). The instrument presents a single vignette consisting of six points of client dialogue to which respondents write 'what they would say next.' In the context of an implementation/effectiveness hybrid trial, 19 staff clinicians at an opiate treatment program completed serial training outcome assessments before, following, and three months after CM training. Assessments included this adaptation of the HRQ, a multiple-choice CM knowledge test, and a recorded standardized patient encounter scored for CM skillfulness. Study results reveal promising psychometric properties for the instrument, including strong scoring reliability, internal consistency, concurrent and predictive validity, test-retest reliability and sensitivity to training effects. These preliminary findings suggest the instrument is a viable, practical method to assess clinician skill in communicative aspects of CM delivery. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Theresa Coles,1 Cheryl Coon,1 Carla DeMuro,1 Lori McLeod,1 Ari Gnanasakthy21Patient-Reported Outcomes, RTI Health Solutions, Research Triangle Park, NC, 2Novartis Pharmaceuticals, East Hanover, NJ, USAAbstract: Inattention and impulsivity symptoms are common among adults with attention-deficit/hyperactivity disorder (ADHD, which can lead to difficulty concentrating, restlessness, difficulty completing tasks, disorganization, impatience, and impulsiveness. Many adults with ADHD find it difficult to focus and prioritize. Resulting outcomes, such as missed deadlines and forgotten engagements, may ultimately impact the ability to function at work, school, home, or in a social environment. The European Medicines Agency guidelines for evaluating medicinal products for ADHD recommend inclusion of both functional outcomes, such as school, social, or work functioning, and outcomes related to symptoms of ADHD in clinical studies of novel medication primary efficacy endpoints. Due to its performance in other disease areas and the relevance of its items as evidenced by content validity analyses, the Sheehan Disability Scale (SDS was chosen to assess functional impairment in ADHD. The aim of this study was to investigate the psychometric properties of the SDS, used as a brief measure of functional impairment in a number of psychiatric disorders, in adult patients with ADHD. To the authors' knowledge, this is the first study to evaluate the reliability of the SDS (based on Cronbach's coefficient alpha and test-retest reliability, its validity (construct and known-groups validity, and its ability to detect change in this patient population. This study also established a preliminary responder definition for the SDS in this study population to determine when change can be considered clinically beneficial in a clinical trial setting. The psychometric results support the use of the SDS subscales (items 1–3 and total score (sum of items 1–3 in an ADHD

    Full Text Available Davidson Trauma Scale (DTS measures the frequency and severity of the posttraumatic Stress Disorder pTSD. Since chile has limited data about validity and reliability of instruments to measure pTSD, this study evaluated psychometric properties of the scale in a sample of 130 adolescents between 13 and 18 years (M= 15,78; DT= 1,40. Some of them were traumatized patients and others were from general population. They answered the DTS, a depression and an anxiety scale. The scale obtained adequate internal consistency scores, showed convergent validity (DTS score was associated moderately, directly and significantly with depression and anxiety scores, and discriminated between clinical sample and general population. DTS seems to be a valid and reliable instrument in chilean adolescents.

    2010-11-01

    To examine the factor structure, internal consistency reliability and concurrent-related validity of the Core Nurse Resource Scale. A cross-sectional survey study design was used to obtain a sample of 149 nurses and nursing staff [Registered Nurse (RNs), Licensed Practical Nurse (LPNs) and Certified Nursing Assistant (CNAs)] working in long-term care facilities. Exploratory factor analysis, Cronbach's alpha and bivariate correlations were used to evaluate validity and reliability. Exploratory factor analysis yielded a scale with 18 items on three factors, accounting for 52% of the variance in scores. Internal consistency reliability for the composite and Core Nurse Resource Scale factors ranged from 0.79 to 0.91. The Core Nurse Resource Scale composite scale and subscales correlated positively with a measure of work engagement (r=0.247-0.572). The initial psychometric evaluation of the Core Nurse Resource Scale demonstrates it is a sound measure. Further validity and reliability assessment will need to be explored and assessed among nurses and other nursing staff working in other practice settings. The intent of the Core Nurse Resource Scale is to evaluate the presence of physical, psychological and social resources of the nursing work environment, to identify workplaces at risk for disengaged (low work engagement) nursing staff and to provide useful diagnostic information to healthcare administrators interested in interventions to improve the nursing work environment. © 2010 The Author.

    2014-01-01

    The purpose of this study was to evaluate the psychometric properties of a new instrument to measure incidence and severity of ostomy complications early in the postoperative period. 71 participants were enrolled, most were men (52%), white (96%), and married or partnered (55%). The mean age of participants was 57 ± 15.09 years (mean ± SD). Fifty-two participants (84%) experienced at least 1 ostomy complication in the 60-day postoperative period. The research setting was 3 acute care settings within a large healthcare system in the Midwestern United States. We developed an evidence-based conceptual model to guide development and evaluation of a new instrument, the Pittman Ostomy Complication Severity Index (OCSI). The OCSI format includes Likert-like scale with 9 individual items scored 0 to 3 and a total score computed by summing the individual items. Higher scores indicate more severe ostomy complications. This study consisted of 2 phases: (1) an expert review, conducted to establish content validity; and (2) a prospective, longitudinal study design, to examine psychometric properties of the instrument. A convenience sample of 71 adult patients who underwent surgery to create a new fecal ostomy was recruited from 3 hospitals. Descriptive analyses, content validity indices, interrater reliability testing, and construct validity testing were employed. Common complications included leakage (60%), peristomal moisture-associated dermatitis (50%), stomal pain (42%), retraction (39%), and bleeding (32%). The OCSI demonstrated acceptable evidence of content validity index (CVI = 0.9) and interrater reliability for individual items (k = 0.71-1.0), as well as almost perfect agreement for total scores among raters (ICC = 0.991, P ≤ .001). Construct validity of the OCSI was supported by significant correlations among variables in the conceptual model (complications, risk factors, stoma care self-efficacy, and ostomy adjustment). OCSI demonstrated acceptable validity and

    Moral injury is an emerging construct related to negative consequences associated with war-zone stressors that transgress military veterans' deeply held values/beliefs. Given the newness of the construct, there is a need for instrumentation that might assess morally injurious experiences (MIEs) in this population. Drawing on a community sample of 131 Iraq and/or Afghanistan Veterans and clinical sample of 82 returning Veterans, we conducted an initial psychometric evaluation of the newly developed Moral Injury Questionnaire-Military version (MIQ-M)-a 20-item self-report measure for assessing MIEs. Possibly due to low rates of reporting, an item assessing sexual trauma did not yield favourable psychometric properties and was excluded from analyses. Veterans in the clinical sample endorsed significantly higher scores across MIQ-M items. Factor analytic results for the final 19 items supported a unidimensional structure, and convergent validity analyses revealed that higher scores (indicative of more MIEs) were correlated with greater general combat exposure, impairments in work/social functioning, posttraumatic stress and depression in the community sample. In addition, when controlling for demographics, deployment-related factors and exposure to life threat stressors associated with combat, tests of incremental validity indicated that MIQ-M scores were also uniquely linked with suicide risk and other mental health outcomes. These findings provide preliminary evidence for the validity of the MIQ-M and support the applicability of this measure for further research and clinical work with Veterans. Military service can confront service members with experiences that undermine their core sense of humanity and violate global values and beliefs. These types of experiences increase the risk for posttraumatic maladjustment in this population, even when accounting for rates of exposure to life threat traumas. Moral injury is an emerging construct to more fully capture the many

    Full Text Available HIV-associated vulnerabilities-especially those linked to psychological issues-and limited mental health-treatment resources have the potential to adversely affect the health statuses of individuals. The concept of resilience has been introduced in the literature to shift the emphasis from vulnerability to protective factors. Resilience, however, is an evolving construct and is measured in various ways, though rarely among underserved, minority populations. Herein, we present the preliminary psychometric properties of a sample of HIV-seropositive Puerto Rican women, measured using a newly developed health-related resilience scale.The Resilience Scales for Children and Adolescents, an instrument with solid test construction properties, acted as a model in the development (in both English and Spanish of the HRRS, providing the same dimensions and most of the same subscales. The present sample was nested within the Hispanic-Latino longitudinal cohort of women (HLLC, that is part of the NeuroAIDS Research Program at the University of Puerto Rico (UPR, Medical Sciences Campus (MSC. Forty-five consecutively recruited, HIV+ women from the HLLC completed a demographic survey, the HRRS, and the Beck Depression Inventory-I, Spanish version.The results demonstrate excellent overall internal consistency for the total HRRS score (α = 0.95. Each of the dimensional scores also evidenced acceptable internal consistency (α ≥ 0.88. All the dimensional and subscale content validity indices were above the 0.42 cut-off. Analysis revealed a significant negative correlation between the HRRS total score and BDI-I-S (r(45 = -0.453, p < 0.003.Albeit preliminary in nature, the present study provides support for the HRRS as a measure to assess resilience among individuals living with chronic medical conditions.

    Emergence delirium and emergence agitation have been a subject of interest since the early 1960s. This behavior has been associated with increased risk of injury in children and dissatisfaction with anesthesia care in their parents. The Pediatric Anesthesia Emergence Delirium Scale is a commonly used instrument for codifying and recording this behavior. The aim of this study was to psychometrically evaluate the Pediatric Anesthesia Emergence Delirium scale, focusing on the factor structure, in a sample of children recovering from anesthesia after surgery or diagnostic procedures. The reliability of the Pediatric Anesthesia Emergence Delirium scale was also tested. One hundred and twenty-two children younger than seven years were observed at postoperative care units during recovery from anesthesia. Two or 3 observers independently assessed the children using the Pediatric Anesthesia Emergence Delirium scale. The factor analysis clearly revealed a one-factor solution, which accounted for 82% of the variation in the data. Internal consistency, calculated with Cronbach's alpha, was good (0.96). The Intraclass Correlation Coefficient, which was used to assess interrater reliability for the Pediatric Anesthesia Emergence Delirium scale sum score, was 0.97 (P Pediatric Anesthesia Emergence Delirium scale for assessing emergence delirium in children recovering from anesthesia after surgery or diagnostic procedures. The kappa statistics for the Pediatric Anesthesia Emergence Delirium scale items essentially indicated good agreement between independent raters, supporting interrater reliability. © 2018 John Wiley & Sons Ltd.

    Unemployment can negatively impact quality of life among patients with schizophrenia. Employment status depends on ability, opportunity, education, and cultural influences. A clinician-rated scale of work readiness, independent of current work status, can be a valuable assessment tool. A series of studies were conducted to create and validate a Work Readiness Questionnaire (WoRQ) for clinicians to assess patient ability to engage in socially useful activity, independent of work availability. Content validity, test-retest and inter-rater reliability, and construct validity were evaluated in three separate studies. Content validity was supported. Cronbach's α was 0.91, in the excellent range. Clinicians endorsed WoRQ concepts, including treatment adherence, physical appearance, social competence, and symptom control. The final readiness decision showed good test-retest reliability and moderate inter-rater reliability. Work readiness was associated with higher function and lower levels of negative symptoms. Low positive and high negative predictive values confirmed the concept validity. The WoRQ has suitable psychometric properties for use in a clinical trial for patients with a broad range of symptom severity. The scale may be applicable to assess therapeutic interventions. It is not intended to assess eligibility for supported work interventions. The WoRQ is suitable for use in schizophrenia clinical trials to assess patient work functional potential.

    This article describes the development and evaluation of an instrument that measures preferences for specific sexual behaviors of heterosexual men and women in a dyadic context. In Study 1, 74 statements of preference were reduced to 46 on the basis of reliability and range of responses. Factor analysis revealed that 27 of the 46 items loaded on 6 factors: Erotophilia, Use of Contraception, Conventionality, Use of Erotica, Use of Drugs/Alcohol, and Romanticism. In Study 2, factor analysis of fresh data from a second sample cross-validated these results. To establish construct validity of the revised 27-item Inventory of Dyadic Heterosexual Preferences (IDHP), relationships between each of its 6 scales and 6 criterion measures were examined. These analyses suggested that the last scale is more accurately characterized by the term Romantic Foreplay. We conclude that the IDHP measures 6 distinct domains of sexual preference with a brief, psychometrically sound instrument. Potential applications of the IDHP, suggestions for future research, and strengths and limitations of the current investigation are discussed.

    The present study aimed to design and evaluate the psychometric properties of the Paternal Adaptation Questionnaire (PAQ). The study was a mixed (qualitative and quantitative) sequential exploratory study. In the qualitative phase, a preliminary questionnaire with 210 items emerged from in-depth interviews with 17 fathers and 15 key informants. In the quantitative phase, psychometric properties of the PAQ were assessed. Considering cutoff points as 1.5 for item impact, 0.49 for content validity ratio (CVR), and 0.7 for content validity index (CVI), items of the questionnaire were reduced from 210 to 132. Assessment of the content validity of the questionnaire demonstrated S-CVR = 0.68 and S-CVI = 0.92. Exploratory factor analysis resulted in the development of a PAQ with 38 items classified under five factors (ability in performing the roles and responsibilities; perceiving the parental development; stabilization in paternal position; spiritual stability and internal satisfaction; and challenges and concerns), which explained 52.19% of cumulative variance. Measurement of internal consistency reported a Cronbach's α of .89 for PAQ (.61-.86 for subscales), and stability assessment of the PAQ through the test-retest demonstrated Spearman's correlation coefficients and intraclass correlation coefficient of .96 (.81-.97 for subscales). It was identified that the PAQ is a valid and reliable instrument that could be used to assess fatherhood adaptation with the paternal roles and fathers' needs, as well as to design appropriate interventions and to evaluate their effectiveness. © The Author(s) 2016.

Social skills measures are commonly used by health professionals to assess and plan the treatment of social skills difficulties. There is a need to comprehensively evaluate the quality of psychometric properties reported across these measures to guide assessment and treatment planning. To conduct a systematic review of the literature on the psychometric properties of social skills and behaviours measures for both children and adults. A systematic search was performed using four electronic databases: CINAHL, PsycINFO, Embase and Pubmed; the Health and Psychosocial Instruments database; and grey literature using PsycExtra and Google Scholar. The psychometric properties of the social skills measures were evaluated against the COSMIN taxonomy of measurement properties using pre-set psychometric criteria. Thirty-Six studies and nine manuals were included to assess the psychometric properties of thirteen social skills measures that met the inclusion criteria. Most measures obtained excellent overall methodological quality scores for internal consistency and reliability. However, eight measures did not report measurement error, nine measures did not report cross-cultural validity and eleven measures did not report criterion validity. The overall quality of the psychometric properties of most measures was satisfactory. The SSBS-2, HCSBS and PKBS-2 were the three measures with the most robust evidence of sound psychometric quality in at least seven of the eight psychometric properties that were appraised. A universal working definition of social functioning as an overarching construct is recommended.

    This is a further development of a specific questionnaire, the 3-set 4P, to be used for measuring former ICU patients' physical and psychosocial problems after intensive care and the need for follow-up. The aim was to psychometrically test and evaluate the 3-set 4P questionnaire in a larger population. The questionnaire consists of three sets: "physical", "psychosocial" and "follow-up". The questionnaires were sent by mail to all patients with more than 24-hour length of stay on four ICUs in Sweden. Construct validity was measured with exploratory factor analysis with Varimax rotation. This resulted in three factors for the "physical set", five factors for the "psychosocial set" and four factors for the "follow-up set" with strong factor loadings and a total explained variance of 62-77.5%. Thirteen questions in the SF-36 were used for concurrent validity showing Spearman's r(s) 0.3-0.6 in eight questions and less than 0.2 in five. Test-retest was used for stability reliability. In set follow-up the correlation was strong to moderate and in physical and psychosocial sets the correlations were moderate to fair. This may have been because the physical and psychosocial status changed rapidly during the test period. All three sets had good homogeneity. In conclusion, the 3-set 4P showed overall acceptable results, but it has to be further modified in different cultures before being considered a fully operational instrument for use in clinical practice.

    To evaluate reproducibility (reliability and agreement) of the Brachial Assessment Tool (BrAT), a new patient-reported outcome measure for adults with traumatic brachial plexus injury (BPI). Prospective repeated-measure design. Outpatient clinics. Adults with confirmed traumatic BPI (N=43; age range, 19-82y). People with BPI completed the 31-item 4-response BrAT twice, 2 weeks apart. Results for the 3 subscales and summed score were compared at time 1 and time 2 to determine reliability, including systematic differences using paired t tests, test retest using intraclass correlation coefficient model 1,1 (ICC 1,1 ), and internal consistency using Cronbach α. Agreement parameters included standard error of measurement, minimal detectable change, and limits of agreement. BrAT. Test-retest reliability was excellent (ICC 1,1 =.90-.97). Internal consistency was high (Cronbach α=.90-.98). Measurement error was relatively low (standard error of measurement range, 3.1-8.8). A change of >4 for subscale 1, >6 for subscale 2, >4 for subscale 3, and >10 for the summed score is indicative of change over and above measurement error. Limits of agreement ranged from ±4.4 (subscale 3) to 11.61 (summed score). These findings support the use of the BrAT as a reproducible patient-reported outcome measure for adults with traumatic BPI with evidence of appropriate reliability and agreement for both individual and group comparisons. Further psychometric testing is required to establish the construct validity and responsiveness of the BrAT. Copyright © 2017 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    Introduction Improving social inclusion opportunities for population health has been identified as a priority area for international policy. There is a need to comprehensively examine and evaluate the quality of psychometric properties of measures of social inclusion that are used to guide social policy and outcomes. Objective To conduct a systematic review of the literature on all current measures of social inclusion for any population group, to evaluate the quality of the psychometric properties of identified measures, and to evaluate if they capture the construct of social inclusion. Methods A systematic search was performed using five electronic databases: CINAHL, PsycINFO, Embase, ERIC and Pubmed and grey literature were sourced to identify measures of social inclusion. The psychometric properties of the social inclusion measures were evaluated against the COSMIN taxonomy of measurement properties using pre-set psychometric criteria. Results Of the 109 measures identified, twenty-five measures, involving twenty-five studies and one manual met the inclusion criteria. The overall quality of the reviewed measures was variable, with the Social and Community Opportunities Profile-Short, Social Connectedness Scale and the Social Inclusion Scale demonstrating the strongest evidence for sound psychometric quality. The most common domain included in the measures was connectedness (21), followed by participation (19); the domain of citizenship was covered by the least number of measures (10). No single instrument measured all aspects within the three domains of social inclusion. Of the measures with sound psychometric evidence, the Social and Community Opportunities Profile-Short captured the construct of social inclusion best. Conclusions The overall quality of the psychometric properties demonstrate that the current suite of available instruments for the measurement of social inclusion are promising but need further refinement.

    Considered a positive body image measure, the 13-item Body Appreciation Scale (BAS; Avalos, Tylka, & Wood-Barcalow, 2005) assesses individuals' acceptance of, favorable opinions toward, and respect for their bodies. While the BAS has accrued psychometric support, we improved it by rewording certain BAS items (to eliminate sex-specific versions and body dissatisfaction-based language) and developing additional items based on positive body image research. In three studies, we examined the reworded, newly developed, and retained items to determine their psychometric properties among college and online community (Amazon Mechanical Turk) samples of 820 women and 767 men. After exploratory factor analysis, we retained 10 items (five original BAS items). Confirmatory factor analysis upheld the BAS-2's unidimensionality and invariance across sex and sample type. Its internal consistency, test-retest reliability, and construct (convergent, incremental, and discriminant) validity were supported. The BAS-2 is a psychometrically sound positive body image measure applicable for research and clinical settings. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The present research describes the development and psychometric evaluation of a second version of the Acceptance and Action Questionnaire (AAQ-II), which assesses the construct referred to as, variously, acceptance, experiential avoidance, and psychological inflexibility. Results from 2,816 participants across six samples indicate the satisfactory structure, reliability, and validity of this measure. For example, the mean alpha coefficient is .84 (.78-.88), and the 3- and 12-month test-retest reliability is .81 and .79, respectively. Results indicate that AAQ-II scores concurrently, longitudinally, and incrementally predict a range of outcomes, from mental health to work absence rates, that are consistent with its underlying theory. The AAQ-II also demonstrates appropriate discriminant validity. The AAQ-II appears to measure the same concept as the AAQ-I (r=.97) but with better psychometric consistency. Copyright © 2011.

    To design and conduct preliminary validation of a measure of hypoglycaemia awareness and problematic hypoglycaemia, the Hypoglycaemia Awareness Questionnaire. Exploratory and cognitive debriefing interviews were conducted with 17 adults (nine of whom were women) with Type 1 diabetes (mean ± sd age 48 ± 10 years). Questionnaire items were modified in consultation with diabetologists/psychologists. Psychometric validation was undertaken using data from 120 adults (53 women) with Type 1 diabetes (mean ± sd age 44 ± 16 years; 50% with clinically diagnosed impaired awareness of hypoglycaemia), who completed the following questionnaires: the Hypoglycaemia Awareness Questionnaire, the Gold score, the Clarke questionnaire and the Problem Areas in Diabetes questionnaire. Iterative design resulted in 33 items eliciting responses about awareness of hypoglycaemia when awake/asleep and hypoglycaemia frequency, severity and impact (healthcare utilization). Psychometric analysis identified three subscales reflecting 'impaired awareness', 'symptom level' and 'symptom frequency'. Convergent validity was indicated by strong correlations between the 'impaired awareness' subscale and existing measures of awareness: (Gold: rs =0.75, P Questionnaire has robust face and content validity; satisfactory structure; internal reliability; convergent, divergent and known groups validity. The impaired awareness subscale and other items contribute significantly to models explaining recall of severe and nocturnal hypoglycaemia. Prospective validation, including determination of a threshold to identify impaired awareness, is now warranted. © 2015 The Authors. Diabetic Medicine © 2015 Diabetes UK.

    Ineffective or inefficient transitions threaten patient safety, hinder communication, and worsen patient outcomes. The Hospital Culture of Transitions (H-CulT) survey was designed to assess a hospital's organizational culture related to within-hospital transitions in care involving patient movement. In this article, psychometric properties of the H-CulT survey were examined to assess and refine the hospital culture of transitions. A cross-sectional, multicenter, multidisciplinary correlational design and survey methods were used to examine the psychometric properties of the H-CulT survey. Exploratory factor analysis was used to quantify the accuracy of the previously identified structure. Specifically, the analysis involved the principal axis factor method with an oblique rotation, based on a polychoric correlation matrix. A sample of 492 respondents from 13 diverse hospitals participated. Cronbach's alpha for the instrument was 0.88, indicating strong internal consistency. Seven subscales emerged and were labeled: Hospital Leadership, Unit Leadership, My Unit's Culture, Other Units' Culture, Busy Workload, Priority of Patient Care, and Use of Data. Correlations between subscales ranged from 0.07 to 0.52, providing evidence that the subscales did not measure the same construct. Subscale correlations with the total score were near or above 0.50 (p <0.001). Use of a factor-loading cutoff of 0.40 resulted in the elimination of 12 items because of weak associations with the topic. The H-CulT is a psychometrically sound and practical survey for assessing hospital culture related to patient flow during transitions in care. Survey results may prompt quality improvement interventions that enhance in-hospital transitions and improve staff satisfaction and patient satisfaction with care.

    Soelberg, N.R.; Reimann, G.A.

    1994-07-01

    The critical constraints for sizing solid radioactive and mixed wastes for subsequent thermal treatment were identified via a literature review and a survey of shredding equipment vendors. The types and amounts of DOE radioactive wastes that will require treatment to reduce the waste volume, destroy hazardous organics, or immobilize radionuclides and/or hazardous metals were considered. The preliminary steps of waste receipt, inspection, and separation were included because many potential waste treatment technologies have limits on feedstream chemical content, physical composition, and particle size. Most treatment processes and shredding operations require at least some degree of feed material characterization. Preliminary cost estimates show that pretreatment costs per unit of waste can be high and can vary significantly, depending on the processing rate and desired output particle size

    2014-04-01

    The most widely implemented offending behaviour programme in the United Kingdom was Enhanced Thinking Skills (ETS), a cognitive-behavioural group intervention that aimed to develop participant's general cognitive skills. A new offending behaviour programme has been developed to replace ETS: the Thinking Skills Programme (TSP). This study reports an evaluation of the effectiveness of TSP using psychometric assessments. Phasing of the two programmes created an opportunity to compare the two programmes consecutively. Forty participants, 20 from each programme, completed a range of psychometric measures to examine cognition, attitudes, and thinking styles. Analysis of pre- and post-programme psychometric results indicated that participants of TSP demonstrated improvements on 14 of the 15 scales, 9 of which were statistically significant. Effect sizes between pre-post results were generally greater for TSP than ETS, demonstrating that TSP had a more positive impact on the thinking styles and attitudes of participants than the ETS programme.

    The objective of this paper is to psychometrically validate the HIV Symptom Distress Scale (SDS), an instrument that can be used to measure overall HIV symptom distress or clinically relevant groups of HIV symptoms. A secondary data analysis was conducted using the Collaborations in HIV Outcomes Research U.S. Cohort (CHORUS). Inclusion criteria required study participants (N=5,521) to have a valid baseline measure of the AIDS Clinical Trial Group Symptom Distress Module, with an SF-12 or SF-36 completed on the same day. Psychometric testing assessed unidimensionality, internal consistency and factor structure using exploratory and confirmatory factor analysis, and structural equation modeling (SEM). Construct validity examined whether the new measure discriminates across clinical significance (CD4 and HIV viral load). Findings show that the SDS has high reliability (α=0.92), and SEM supports a correlated second-order factor model (physical and mental distress) with acceptable fit (GFI=0.88, AGFI=0.85, NFI=0.99, NNFI=0.99; RMSEA=0.06, [90% CI 0.06 – 0.06]; Satorra Bentler Scaled, C2 =3274.20; p=0.0). Construct validity shows significant differences across categories for HIV-1 viral load (p< 0.001) and CD4 (p< 0.001). Differences in mean SDS scores exist across gender (p< 0.001), race/ethnicity (p< 0.05) and educational attainment (p < 0.001). Hence, the HIV Symptom Distress Scale is a reliable and valid instrument, which measures overall HIV symptoms or clinically relevant groups of symptoms. PMID:22409246

    Decreased appetite in heart failure (HF) may lead to undernutrition which could negatively influence prognosis. Appetite is a complex clinical issue that is often best measured with the use of self-report instruments. However, there is a lack of self-rated appetite instruments. The Council on Nutrition Appetite Questionnaire (CNAQ) and the Simplified Nutritional Appetite Questionnaire (SNAQ) are validated instruments developed primarily for elderly people. Yet, the psychometric properties have not been evaluated in HF populations. The aim of the present study was to evaluate the psychometric properties of CNAQ and SNAQ in patients with HF. A total of 186 outpatients with reduced ejection fraction and New York Heart Association (NYHA) functional classifications II-IV were included (median age 72 y; 70% men). Data were collected with the use of a questionnaire that included the CNAQ and SNAQ. The psychometric evaluation included data quality, factor structure, construct validity, known-group validity, and internal consistency. Unidimensionality was supported by means of parallel analysis and confirmatory factor analyses (CFAs). The CFA results indicated sufficient model fit. Both construct validity and known-group validity were supported. Internal consistency reliability was acceptable, with ordinal coefficient alpha estimates of 0.82 for CNAQ and 0.77 for SNAQ. CNAQ and SNAQ demonstrated sound psychometric properties and can be used to measure appetite in patients with HF. Copyright © 2015 Elsevier Inc. All rights reserved.

    2015-03-01

    The Cross-Cultural Loss Scale (CCLS), a measure of loss associated with crossing national boundaries, was developed across 2 samples of international students. With Sample 1 (N = 262), exploratory factor analyses were used to select the 14 CCLS items and to determine 3 factors: Belonging-Competency (α = .87), National Privileges (α = .68), and Access to Home Familiarity (α = .72). With Sample 2, confirmatory factor analyses (N = 256) cross-validated the 3-factor oblique model as well as a bifactor model. Cronbach alphas of CCLS subscale scores in Sample 2 ranged from .73 to .87. The validity of the CCLS scores was supported by its associations with related variables in the expected directions. Perceived cross-cultural losses were positively associated with negative affect, migration grief and loss, and discrimination and were negatively associated with life satisfaction, positive affect, general self-efficacy, and social connection with mainstream society. Moreover, the CCLS total and 2 subscale scores added significant incremental variance in predicting subjective well-being over and above related constructs. The results indicated measurement invariance and validity equivalency for the CCLS scores between men and women. The overall results from these 2 samples support CCLS as a psychometrically strong measure. 2015 APA, all rights reserved

    2004-11-01

    This article describes the development and psychometric properties of the Multidimensional Neglectful Behavior Scale-Child Report (MNBS-CR). The measure is broadly conceptualized to tap child neglect across four core domains: cognitive, emotional, physical and supervisory neglect, and it assesses exposure to violence, alcohol-related neglect, abandonment, and children's appraisals of parenting. Features include pictorial items, audio computer-assisted testing, and programming by age and gender of the child and caregiver. A clinical sample of 144 children, age 6 to 15 years, and a comparison sample of 87 children were tested. Results showed that the MNBS-CR has high reliability, with higher reliability found for older children (alpha = .94) than for younger children (alpha = .66). Among older children, the MNBS-CR Supervisory scale was significantly associated with the Child Behavior Check List (CBCL), and total MNBS-CR scores were significantly associated with clinician reports of behavioral disorders. Younger and older neglected children scored significantly higher on the MNBS-CR than community children.

    Full Text Available Schema Therapy (ST is a well-known approach for the treatment of personality disorders. This therapy integrates different theories and techniques into an original and systematic treatment model. The Young Schema Questionnaire L-3 (YSQ-L3 is a self-report instrument, based on the ST model, designed to assess 18 Early Maladaptive Schemas (EMSs. During the last decade, it has been translated and validated in different countries and languages. This study aims to establish the psychometric properties of the Italian Version of the YSQ-L3. We enrolled two groups: a clinical (n = 148 and a non-clinical one (n = 918. We investigated the factor structure, reliability and convergent validity with anxiety and depression between clinical and non-clinical groups. The results highlighted a few relevant findings. Cronbach's alpha showed significant values for all the schemas. All of the factor models do not seem highly adequate, even if the hierarchical model has proven to be the most significant one. Furthermore, the questionnaire confirms the ability to discriminate between clinical and non-clinical groups and could represent a useful tool in the clinical practice. Limitations and future directions are discussed.

    The alleviation of distress associated with death and dying is a central goal of palliative care, despite the lack of routine measurement of this outcome. In this study, we introduce the Death and Dying Distress Scale (DADDS), a new, brief measure we have developed to assess death-related anxiety in advanced cancer and other palliative populations. We describe its preliminary psychometrics based on a sample of 33 patients with advanced or metastatic cancer. The DADDS broadly captures distress about the loss of time and opportunity, the process of death and dying, and its impact on others. The initial version of the scale has a one-factor structure and good internal reliability. Dying and death-related distress was positively associated with depression and negatively associated with spiritual, emotional, physical, and functional well-being, providing early evidence of construct validity. This distress was relatively common, with 45% of the sample scoring in the upper reaches of the scale, suggesting that the DADDS may be a relevant outcome for palliative intervention. We conclude by presenting a revised 15-item version of the scale for further study in advanced cancer and other palliative populations.

    Full Text Available Objective. The Geriatric Depression Scale (GDS is an evaluation tool to diagnose older adult’s depression. This questionnaire was defined by Yesavage and Brink in 1982; it was designed expressly for the older person and defines his/her degree of satisfaction, quality of life, and feelings. The objective of this study is to evaluate the psychometric properties of the Italian translation of the Geriatric Depression Scale (GDS-IT. Methods. The Italian version of the Geriatric Depression Scale was administered to 119 people (79 people with a depression diagnosis and 40 healthy ones. We examined the following psychometric characteristics: internal consistency reliability, test-retest reliability, concurrent validity, and construct validity (factor structure. Results. Cronbach’s Alpha for the GDS-IT administered to the depressed sample was 0.84. Test-retest reliability was 0.91 and the concurrent validity was 0.83. The factorial analysis showed a structure of 5 factors, and the scale cut-off is between 10 and 11. Conclusion. The GDS-IT proved to be a reliable and valid questionnaire for the evaluation of depression in an Italian population. In the present study, the GDS-IT showed good psychometric properties. Health professionals now have an assessment tool for the evaluation of depression symptoms in the Italian population.

    To evaluate the internal consistency of the Mayo-Portland Adaptability Inventory (MPAI), further refine the instrument, and provide reference data based on a large, geographically diverse sample of persons with acquired brain injury (ABI). 386 persons, most with moderate to severe ABI. Outpatient, community-based, and residential rehabilitation facilities for persons with ABI located in the United States: West, Midwest, and Southeast. Rasch, item cluster, principal components, and traditional psychometric analyses for internal consistency of MPAI data and subscales. With rescoring of rating scales for 4 items, a 29-item version of the MPAI showed satisfactory internal consistency by Rasch (Person Reliability=.88; Item Reliability=.99) and traditional psychometric indicators (Cronbach's alpha=.89). Three rationally derived subscales for Ability, Activity, and Participation demonstrated psychometric properties that were equivalent to subscales derived empirically through item cluster and factor analyses. For the 3 subscales, Person Reliability ranged from.78 to.79; Item Reliability, from.98 to.99; and Cronbach's alpha, from.76 to.83. Subscales correlated moderately (Pearson r =.49-.65) with each other and strongly with the overall scale (Pearson r=.82-.86). Outcome after ABI is represented by the unitary dimension described by the MPAI. MPAI subscales further define regions of this dimension that may be useful for evaluation of clinical cases and program evaluation.

    There is a paucity of instruments designed to evaluate the multiple dimensions of the workplace as an educational environment for undergraduate medical students. The aim was to develop and psychometrically evaluate an instrument to measure how undergraduate medical students perceive the clinical workplace environment, based on workplace learning theories and empirical findings. Development of the instrument relied on established standards including theoretical and empirical grounding, systematic item development and expert review at various stages to ensure content validity. Qualitative and quantitative methods were employed using a series of steps from conceptualization through psychometric analysis of scores in a Swedish medical student population. The final result was a 25-item instrument with two overarching dimensions, experiential learning and social participation, and four subscales that coincided well with theory and empirical findings: Opportunities to learn in and through work & quality of supervision; Preparedness for student entry; Workplace interaction patterns & student inclusion; and Equal treatment. Evidence from various sources supported content validity, construct validity and reliability of the instrument. The Undergraduate Clinical Education Environment Measure represents a valid, reliable and feasible multidimensional instrument for evaluation of the clinical workplace as a learning environment for undergraduate medical students. Further validation in different populations using various psychometric methods is needed.

    The objectives of this study were to develop a questionnaire that evaluates the perception of nursing workers to job factors that may contribute to musculoskeletal symptoms, and to evaluate its psychometric properties. Internationally recommended methodology was followed: construction of domains, items and the instrument as a whole, content validity, and pre-test. Psychometric properties were evaluated among 370 nursing workers. Construct validity was analyzed by the factorial analysis, known-groups technique, and convergent validity. Reliability was assessed through internal consistency and stability. Results indicated satisfactory fit indices during confirmatory factor analysis, significant difference (p office workers, and moderate correlations between the new questionnaire and Numeric Pain Scale, SF-36 and WRFQ. Cronbach's alpha was close to 0.90 and ICC values ranged from 0.64 to 0.76. Therefore, results indicated that the new questionnaire had good psychometric properties for use in studies involving nursing workers. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

    To describe the Professional Practice Environment (PPE) scale, its conceptual development and psychometric evaluation, and its uses in measuring eight characteristics of the professional practice environment in an acute care setting. The 38-item PPE Scale was validated on a sample of 849 professional practice staff at the Massachusetts General Hospital in Boston. Psychometric analysis included: item analysis, principal components analysis (PCA) with varimax rotation and Kaiser normalization, and internal consistency reliability using Cronbach's alpha coefficient. Eight components were shown, confirming the original conceptually derived model's structure and accounting for 61% of explained variance. Cronbach's alpha coefficients for the eight PPE subscales ranged from .78 to .88. Findings showed the 38-item PPE Scale was reliable and valid for use in health outcomes research to examine the professional practice environment of staff working in acute care settings.

    The current study cross-culturally evaluated the psychometric properties of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2)/MMPI-2-Restructured Form Restructured Clinical (RC) Scales in psychiatric settings in Israel with a sample of 100 men and 133 women. Participants were administered the MMPI-2 and were rated by their therapists on a 188-item Patient Description Form. Results indicated that in most instances the RC Scales demonstrated equivalent or better internal consistencies and improved intercorrelation patterns relative to their clinical counterparts. Furthermore, external analyses revealed comparable or improved convergent validity (with the exceptions of Antisocial Behavior [RC4] and Ideas of Persecution [RC6] among men), and mostly greater discriminant validity. Overall, the findings indicate that consistent with previous findings, the RC Scales generally exhibit comparable to improved psychometric properties over the Clinical Scales. Implications of the results, limitations, and recommendations for future research are discussed. © The Author(s) 2014.

    Patients with heart failure can experience thirst distress. However, there is no instrument to measure this in patients with heart failure. The aim of the present study was to develop the Thirst Distress Scale for patients with Heart Failure (TDS-HF) and to evaluate psychometric properties of the scale. The TDS-HF was developed to measure thirst distress in patients with heart failure. Face and content validity was confirmed using expert panels including patients and healthcare professionals. Data on the TDS-HF was collected from patients with heart failure at outpatient heart failure clinics and hospitals in Sweden, the Netherlands and Japan. Psychometric properties were evaluated using data from 256 heart failure patients (age 72±11 years). Concurrent validity of the scale was assessed using a thirst intensity visual analogue scale. Patients did not have any difficulties answering the questions, and time taken to answer the questions was about five minutes. Factor analysis of the scale showed one factor. After psychometric testing, one item was deleted. For the eight item TDS-HF, a single factor explained 61% of the variance and Cronbach's alpha was 0.90. The eight item TDS-HF was significantly associated with the thirst intensity score ( r=0.55, pfailure.

    Full Text Available The experience achieved using the tool “Questionnaires,” available inside the Virtual Campus of an architectural engineering school in northeast Spain, is presented. “Questionnaires” is a mechanism/tool adequate and simple to evaluate the knowledge level achieved by students. This work shows and identifies the control indices of adaptation for questionnaires, such as the Facility Index, the standard deviation, the Discrimination Index, and the Discrimination Coefficient. From these parameters, educational performance is inferred, identified, and predicted. The conclusions of this work will allow the modification of deficient knowledge-evaluation practices and the identification of needs for specific groups or for students with particular requirements, thus making it feasible to apply these parameters with a guarantee of success in similar evaluation processes.

    Full Text Available Abstract Background The MacDQoL is an individualised measure of the impact of macular degeneration (MD on quality of life (QoL. There is preliminary evidence of its psychometric properties and sensitivity to severity of MD. The aim of this study was to carry out further psychometric evaluation with a larger sample and investigate the measure's sensitivity to MD severity. Methods Patients with MD (n = 156: 99 women, 57 men, mean age 79 ± 13 years, recruited from eye clinics (one NHS, one private completed the MacDQoL by telephone interview and later underwent a clinic vision assessment including near and distance visual acuity (VA, comfortable near VA, contrast sensitivity, colour recognition, recovery from glare and presence or absence of distortion or scotoma in the central 10° of the visual field. Results The completion rate for the MacDQoL items was 99.8%. Of the 26 items, three were dropped from the measure due to redundancy. A fourth was retained in the questionnaire but excluded when computing the scale score. Principal components analysis and Cronbach's alpha (0.944 supported combining the remaining 22 items in a single scale. Lower MacDQoL scores, indicating more negative impact of MD on QoL, were associated with poorer distance VA (better eye r = -0.431 p Conclusion The MacDQoL 22-item scale has excellent internal consistency reliability and a single-factor structure. The measure is acceptable to respondents and the generic QoL item, MD-specific QoL item and average weighted impact score are related to several measures of vision. The MacDQoL demonstrates that MD has considerable negative impact on many aspects of QoL, particularly independence, leisure activities, dealing with personal affairs and mobility. The measure may be valuable for use in clinical trials and routine clinical care.

    Cerebral vision disorders (CVDs) are frequent after brain damage and impair the patient's outcome. Yet clinically and psychometrically validated procedures for the anamnesis of CVD are lacking. To evaluate the clinical validity and psychometric qualities of the Cerebral Vision Screening Questionnaire (CVSQ) for the anamnesis of CVD in individuals poststroke. Analysis of the patients' subjective visual complaints in the 10-item CVSQ in relation to objective visual perimetry, tests of reading, visual scanning, visual acuity, spatial contrast sensitivity, light/dark adaptation, and visual depth judgments. Psychometric analyses of concurrent validity, specificity, sensitivity, positive/negative predictive value, and interrater reliability were also done. Four hundred sixty-one patients with unilateral (39.5% left, 47.5% right) or bilateral stroke (13.0%) were included. Most patients were assessed in the chronic stage, on average 36.7 (range = 1-620) weeks poststroke. The majority of all patients (96.4%) recognized their visual symptoms within 1 week poststroke when asked for specifically. Mean concurrent validity of the CVSQ with objective tests was 0.64 (0.54-0.79, P reliability was 0.76 for a 1-week interval between both assessments (all P guides the clinician in the selection of necessary assessments and appropriate neurovisual therapies for the patient. © The Author(s) 2015.

    Full Text Available Sport psychologist needs to understand how psychological factors affect athletic performance of an individual, considering individual differences among athletes. Each specific problem in working with athletes must be considered depending on complex factors: the type (specificity of sport; characteristics of the activity (the training or competition; stages of athletes’ sports development; gender and age differences, etc. Although there are numerous psychological instruments, which assess psychological characteristics of athletes, it is important to select instruments adjusted to athletes, working style of sports psychologist, available time and other constraints. Here, we have formulated a preliminary version of our own battery of questionnaires, named Multi¬di¬men¬sional Inventory of Sport Excellence (MUSI, selecting the items for following psychological characteristics: energizing, main¬tain¬ing attention, directing attention, wide internal / external attention and narrow internal / external attention. In this phase of the stu¬dy, participants were stratified only by gender. Sample of 248 participants was examined, of which 103 male athletes (age 24.52 ± 11.80 years and 145 female athletes (age 16.61 ± 6.69 years, from the Croatian sports clubs, competing in 16 different sports (archery, football, handball, bocce, bowling, cycling, karate, rowing, tennis, volleyball, basketball, synchronized swimming, tri¬a¬t¬h¬lon, table tennis, chess, badminton. Data were collected from March to June 2014 in Rijeka, during the trainings in sports clubs. Results of Principal Component Analysis and the reliabilities type internal consistency showed that each of sub-question¬na¬ires from battery MUSI have satisfactory reliability and construct validity, giving positive guidance for future adaptation of the que¬stion¬naire to specific subpopulations of athletes.

    Neglect poses a significant risk for children throughout their development and is often linked with serious consequences that reach into adulthood. The Child Neglect Questionnaire (CNQ) fills existing gaps by incorporating multiple perspectives from both parents and the child, as well as measuring the complex phenomenon of neglect multidimensionally. Furthermore, this measure addresses the need for an instrument specifically developed for late childhood (ages 10-12), as much of the extant evidence and corresponding measures focus on young children and their mothers. A panel of three psychologists, using Cicchetti's model of child neglect as a theoretical guide, began by selecting items from an existing database. Results of exploratory and confirmatory factor analyses and item response theory demonstrated the unidimensionality of physical, emotional, educational, and supervision neglect as well as a second-order construct of child neglect. Analyses controlling for risk status due to father's substance use disorder, socioeconomic status, and child's ethnicity demonstrated that father's and mother's (parental) neglect, particularly in the child's versions, had sound concurrent and predictive validity. Concurrently, at age 10-12, the child's version of both parents' neglect correlated with their parenting behaviors evaluated by other available measures. Prospectively, from 10-12 years of age to 11-13 years of age, parental neglect predicted child's drug use frequency with coexisting psychological dysregulation, psychiatric symptoms, antisocial behavior, non-normative sexual behavior, involvement with deviant peers and leisure activities thus demonstrating sound predictive validity. Also, internal consistency and inter-rater reliability were excellent. The CNQ, particularly the child's version, may thus be useful for detecting children at high risk for parental neglect. © The Author(s) 2014.

    Evaluation of nursing instructors' clinical teaching performance is a prerequisite to the quality assurance of nursing education. One of the most common procedures for this purpose is using student evaluations. This study was to develop and evaluate the psychometric properties of Nursing Instructors' Clinical Teaching Performance Inventory (NICTPI). The primary items of the inventory were generated by reviewing the published literature and the existing questionnaires as well as consulting with the members of the Faculties Evaluation Committee of the study setting. Psychometric properties were assessed by calculating its content validity ratio and index, and test-retest correlation coefficient as well as conducting an exploratory factor analysis and an internal consistency assessment. The content validity ratios and indices of the items were respectively higher than 0.85 and 0.79. The final version of the inventory consisted of 25 items, and in the exploratory factor analysis, items were loaded on three factors which jointly accounting for 72.85% of the total variance. The test-retest correlation coefficient and the Cronbach's alpha of the inventory were 0.93 and 0.973, respectively. The results revealed that the developed inventory is an appropriate, valid, and reliable instrument for evaluating nursing instructors' clinical teaching performance.

    To conduct a psychometric analysis to determine the adequacy of instruments that measure cognition in Alzheimer's disease trials. Both the Alzheimer's Disease Assessment Scale - Cognition (ADAS-Cog) and the Neuropsychological Test Battery (NTB) are validated outcome measures for clinical trials in Alzheimer's disease and are approved also for regulatory purposes. However, it is not clear how comparable they are in measuring cognitive function. In fact, many recent trials in Alzheimer's disease patients have failed and it has been questioned if ADAS-Cog still is a sensitive measure. The present paper examines the psychometric properties of ADAS-Cog and NTB, based on a post hoc analysis of data from a clinical trial (NCT01024660), which was conducted by AstraZeneca, in mild-to-moderate Alzheimer's disease (AD) patients, with a Mini Mental State Examination (MMSE) Total score 16-24. Acceptability, reliability, different types of validity and ability to detect change were assessed using relevant statistical methods. Total scores of both tests, as well as separate domains of both tests, including the Wechsler Memory Scale (WMS), Rey Auditory Verbal Learning Test (RAVLT) and Delis-Kaplan Executive Function System (D-KEFS) Verbal Fluency Condition, were analyzed. Overall, NTB performed well, with acceptable reliability and ability to detect change, while ADAS-Cog had insufficient psychometric properties, including ceiling effects in 8 out of a total of 11 ADAS-Cog items in mild AD patients, as well as low test-retest reliability in some of the items. Based on a direct comparison on the same patient sample, we see advantages of the NTB compared with the ADAS-Cog for the evaluation of cognitive function in the population of mild-to-moderate AD patients. The results suggest that not all of ADAS-Cog items are relevant for both mild and moderate AD population. This validation study demonstrates satisfactory psychometric properties of the NTB, while ADAS-Cog was found to be

    The clinical learning environment is fundamental to nursing education paths, capable of affecting learning processes and outcomes. Several instruments have been developed in nursing education, aimed at evaluating the quality of the clinical learning environments; however, no systematic review of the psychometric properties and methodological quality of these studies has been performed to date. The aims of the study were: 1) to identify validated instruments evaluating the clinical learning environments in nursing education; 2) to evaluate critically the methodological quality of the psychometric property estimation used; and 3) to compare psychometric properties across the instruments available. A systematic review of the literature (using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines) and an evaluation of the methodological quality of psychometric properties (using the COnsensus-based Standards for the selection of health Measurement INstruments guidelines). The Medline and CINAHL databases were searched. Eligible studies were those that satisfied the following criteria: a) validation studies of instruments evaluating the quality of clinical learning environments; b) in nursing education; c) published in English or Italian; d) before April 2016. The included studies were evaluated for the methodological quality of the psychometric properties measured and then compared in terms of both the psychometric properties and the methodological quality of the processes used. The search strategy yielded a total of 26 studies and eight clinical learning environment evaluation instruments. A variety of psychometric properties have been estimated for each instrument, with differing qualities in the methodology used. Concept and construct validity were poorly assessed in terms of their significance and rarely judged by the target population (nursing students). Some properties were rarely considered (e.g., reliability, measurement error

    Cost-prohibitive factors currently prevent a warranted integration of neuropsychological screenings into routine psychiatric evaluations, as a standard of care. To overcome this challenge, the current study examined the psychometric properties of a new computerized measure-the CNS Screen. One hundred and twenty six psychiatric inpatients completed the CNS Screen, the Montreal Cognitive Assessment (MoCA), and the Quick Inventory of Depressive Symptomatology-Self Rated (QIDS-SR₁₆) on the day of hospital discharge. Statistical analysis established convergent validity with a moderate correlation between the self-administered CNS Screen and the clinician-administered MoCA (r=0.64). Discriminant validity was implicated by a non-significant correlation with the QIDS-SR₁₆. Concurrent validity was supported by a moderate, negative correlation with patients' age (r=-0.62). In addition, consistent with previous findings, patients with psychotic disorders exhibited significantly poorer performance on the CNS Screen than patients with a mood disorder. Similarly, patients with a formal disability status scored significantly lower than other patients. The CNS Screen was well tolerated by all patients. With further development, this type of measure may provide a cost-effective approach to expanding neuropsychological screenings on inpatient psychiatric units. Copyright © 2014 Elsevier Ireland Ltd.

    To develop and psychometrically test the Essentials of Magnetism II in nursing homes. Increasing numbers and complex needs of older people in nursing homes strain the nursing workforce. Fewer adequately trained staff and increased care complexity raise concerns about declining quality. Nurses' practice environment has been reported to affect quality of care and productivity. The Essentials of Magnetism II © measures processes and relationships of practice environments that contribute to productivity and quality of care and can therefore be useful in identifying processes requiring change to pursue excellent practice environments. However, this instrument was not explicitly evaluated for its use in nursing home settings so far. In a preparatory phase, a cross-sectional survey study focused on face validity of the essentials of magnetism in nursing homes. A second cross-sectional survey design was then used to further test the instrument's validity and reliability. Psychometric testing included evaluation of content and construct validity, and reliability. Nurses (N = 456) working at 44 units of three nursing homes were included. Respondent acceptance, relevance and clarity were adequate. Five of the eight subscales and 54 of the 58 items did meet preset psychometric criteria. All essentials of magnetism are considered relevant for nursing homes. The subscales Adequacy of Staffing, Clinically Competent Peers, Patient Centered Culture, Autonomy and Nurse Manager Support can be used in nursing homes without problems. The other subscales cannot be directly applied to this setting. The valid subscales of the Essentials of Magnetism II instrument can be used to design excellent nursing practice environments that support nurses' delivery of care. Before using the entire instrument, however, the other subscales have to be improved. © 2016 John Wiley & Sons Ltd.

    To evaluate the effects of centrally active drugs using a new indigenously developed automated psychometric test system and compare the results with that obtained using pencil- and paper-based techniques. The tests were standardized in 24 healthy participants. Reproducibility of the test procedure was evaluated by performing the tests by a single experimenter on two occasions (interday reproducibility). To evaluate the sensitivity of the tests, the effects of zolpidem (5 mg) and caffeine (500 mg) versus placebo were studied in 24 healthy participants in a randomized, double-blind three-way crossover design. Psychometric tests were performed at baseline and at 1, 2, and 3 h after administration of study medication. The effects of zolpidem and caffeine on the psychomotor performance were most pronounced 1 h after administration. At this time, a significant impairment of performance in the simple reaction test (SRT), choice discrimination test (CDT), digit symbol substitution test (DSST), digit vigilance test (DVT), and card sorting test (CST) was observed with zolpidem. In contrast, caffeine showed a significant improvement in performance in CDT and DVT only. The results suggest that the tests of the computerized system are more sensitive and reliable then the pencil and paper tests in detecting the effects of central acting agents and are suitable for use in clinical areas to conduct studies with patients.

There is scarcity of literature about availability of standardized questionnaires for assessing dietary habits of type 2 diabetics in Saudi Arabia. As dietary habits vary from country to country, therefore, this was an attempt to develop questionnaires that can serve as a baseline. Through intensive literature review, four questionnaires were developed / modified and subsequently tested for psychometric properties. Prior to pilot study, a pre-test was conducted to evaluate the face validity and content validity. The pilot study was conducted from 23 October - 22 November, 2016 to evaluate the questionnaires’ reliability and validity. Systematic random sampling technique was used to collect the data from 132 patients by direct investigation method. Questionnaires assessing diabetes mellitus knowledge (0.891), dietary knowledge (0.869), dietary attitude (0.841) and dietary practices (0.874) had good internal consistency reliability. Factor analysis conducted on dietary attitude questionnaire showed a valid 5 factor solution. Directions of loadings were positive and free from factorial complexity. Relying on the data obtained from type 2 diabetics, these questionnaires can be considered as reliable and valid for the assessment of dietary habits in Saudi Arabia and neighbouring Gulf countries population.

    To develop and psychometrically evaluate an information literacy (IL) self-efficacy survey and an IL knowledge test. In this test-retest reliability study, a 25-item IL self-efficacy survey and a 50-item IL knowledge test were developed and administered to a convenience sample of 53 chiropractic students. Item analyses were performed on all questions. The IL self-efficacy survey demonstrated good reliability (test-retest correlation = 0.81) and good/very good internal consistency (mean κ = .56 and Cronbach's α = .92). A total of 25 questions with the best item analysis characteristics were chosen from the 50-item IL knowledge test, resulting in a 25-item IL knowledge test that demonstrated good reliability (test-retest correlation = 0.87), very good internal consistency (mean κ = .69, KR20 = 0.85), and good item discrimination (mean point-biserial = 0.48). This study resulted in the development of three instruments: a 25-item IL self-efficacy survey, a 50-item IL knowledge test, and a 25-item IL knowledge test. The information literacy self-efficacy survey and the 25-item version of the information literacy knowledge test have shown preliminary evidence of adequate reliability and validity to justify continuing study with these instruments.

    The Hypogonadism Impact of Symptoms Questionnaire Short Form (HIS-Q-SF) is a patient-reported outcome measurement designed to evaluate the symptoms of hypogonadism. The HIS-Q-SF is an abbreviated version including17 items from the original 28-item HIS-Q. To conduct item analyses and reduction, evaluate the psychometric properties of the HIS-Q-SF, and provide guidance on score interpretation. A 12-week observational longitudinal study of hypogonadal men was conducted as part of the original HIS-Q psychometric evaluation. Participants completed the original HIS-Q every 2 weeks. Blood samples were collected to evaluate testosterone levels. Participants completed the Aging Male's Symptoms Scale, the International Index of Erectile Function, the Short Form-12, and the PROMIS Sexual Activity, Satisfaction with Sex Life, Sleep Disturbance, and Applied Cognition Scales (baseline and weeks 6 and 12). Clinicians completed the Clinical Global Impression of Severity and Change scales and a clinical form. Item performance was evaluated using descriptive statistics and Rasch analyses. Reliability (internal consistency and test-retest), validity (concurrent and know groups), and responsiveness were assessed. One hundred seventy-seven men participated (mean age = 54.1 years, range = 23-83). Similar to the full HIS-Q, the final abbreviated HIS-Q-SF instrument includes five domains (sexual, energy, sleep, cognition, and mood) with two sexual subdomains (libido and sexual function). For key domains, test-retest reliability was very good, and construct validity was good for all domains. Known-groups validity was demonstrated for all domain scores, subdomain scores, and total score based on the Clinical Global Impression-Severity. All domains and subdomains were responsive to change based on patient-rated anchor questions. The HIS-Q-SF could be a useful tool in clinical practice, epidemiologic studies, and other academic research settings. Careful consideration was given to the

    Full Text Available The OAV questionnaire has been developed to integrate research on altered states of consciousness (ASC. It measures three primary and one secondary dimensions of ASC that are hypothesized to be invariant across ASC induction methods. The OAV rating scale has been in use for more than 20 years and applied internationally in a broad range of research fields, yet its factorial structure has never been tested by structural equation modeling techniques and its psychometric properties have never been examined in large samples of experimentally induced ASC.The present study conducted a psychometric evaluation of the OAV in a sample of psilocybin (n = 327, ketamine (n = 162, and MDMA (n = 102 induced ASC that was obtained by pooling data from 43 experimental studies. The factorial structure was examined by confirmatory factor analysis, exploratory structural equation modeling, hierarchical item clustering (ICLUST, and multiple indicators multiple causes (MIMIC modeling. The originally proposed model did not fit the data well even if zero-constraints on non-target factor loadings and residual correlations were relaxed. Furthermore, ICLUST suggested that the "oceanic boundlessness" and "visionary restructuralization" factors could be combined on a high level of the construct hierarchy. However, because these factors were multidimensional, we extracted and examined 11 new lower order factors. MIMIC modeling indicated that these factors were highly measurement invariant across drugs, settings, questionnaire versions, and sexes. The new factors were also demonstrated to have improved homogeneities, satisfactory reliabilities, discriminant and convergent validities, and to differentiate well among the three drug groups.The original scales of the OAV were shown to be multidimensional constructs. Eleven new lower order scales were constructed and demonstrated to have desirable psychometric properties. The new lower order scales are most likely better suited to

    Translate the Essentials of Magnetism II© (EOMII; Dutch Nurses' Association, Utrecht, The Netherlands) and assess its psychometric properties in a culture different from its origin. The EOMII, developed in the USA, measures the extent to which organizations/units provide healthy, productive and satisfying work environments. As many healthcare organizations are facing difficulties in attracting and retaining staff nurses, the EOMII provides the opportunity to assess the health and effectiveness of work environments. A three-phased (respectively N = 13, N = 74 and N = 2542) combined descriptive and correlational design was undertaken for translation and evaluation validity and psychometric qualities of the EOMII for Dutch hospitals (December 2009-January 2010). We performed forward-backward translation, face and content validation via cross-sectional survey research, and semi-structured interviews on relevance, clarity, and recognizability of instruments' items. Psychometric testing included principal component analysis using varimax rotation, item-total statistics, and reliability in terms of internal consistency (Cronbach's α) for the total scale and its subscales. Face validity was confirmed. Items were recognizable, relevant and clear. Confirmatory factor analysis indicated that five of eight subscales formed clear factors. Three original subscales contained two factors. Item-total correlations ranged from 0.43 to 0.83. One item correlated weakly (0.24) with its subscale. Cronbach's α for the entire scale was 0.92 and ranged from 0.58 to 0.92 for eight subscales. Dutch-translated EOMII (D-EOMII) demonstrated acceptable reliability and validity for assessing hospital staff nurses' work environment. The D-EOMII can be useful and effective in identifying areas in which change is needed for a hospital to pursue an excellent work environment that attracts and retains well-qualified nurses. © 2013 International Council of Nurses.

    Arterial puncture for arterial blood gases (ABG) analysis can be a risky, painful, difficult-to-perform procedure that is often insufficiently practised and generates stress and discomfort amongst patients and healthcare professionals. Self-efficacy is a key component in the acquisition of procedural skills. Therefore, professionals' self-efficacy in arterial puncture should be measured before attempting the procedure on real patients. To develop and psychometrically assess a self-efficacy scale in arterial puncture. An observational cross-sectional design was used in this study. Faculty of Education Sciences, Nursing and Physiotherapy in a higher education institution in the south of Spain. A convenience sample of 342 nursing students entered and completed the study. All participants met the following inclusion criteria: (1) ≥18years old and (2) enrolled in a nursing degree programme during the 2014/2015 academic year. Participants were 74% female (n=254) and their age ranged from 18 to 50, with a mean age of 21.74years (SD=5.14). The Arterial Puncture Self-Efficacy Scale (APSES) was developed and psychometrically tested. Reliability and content validity were studied. Predictive validity and concurrent validity assessed criterion validity. In addition, principal component analysis and known-group analysis evaluated construct validity. Principal component analysis revealed the two-subscale structure of the final 22-item version of the Arterial Puncture Self-Efficacy Scale (APSES). A total Cronbach's alpha coefficient of 0.97 showed its high reliability. The APSES' content validity index was excellent (S-CVI/Ave=0.95). Predictive and concurrent validity analysis demonstrated the good criterion validity of the tool. Supporting the APSES' sensitivity and specificity, known-groups analysis evidenced significant differences (pgood psychometric properties for measuring self-efficacy in arterial puncture for ABG analysis.

    Full Text Available Objective: To describe the cross-cultural adaptation of the Affective Reactivity Index (ARI to Brazilian Portuguese and to investigate preliminary psychometric properties of the adapted version. Methods: Cross-cultural adaptation was based on the investigation of the theoretical and operational equivalences of the original ARI in the Brazilian context, followed by a process of translation, back-translation, and review by a committee of experts. Data analysis was carried out in a community sample of 133 schoolchildren aged 8 to 17 years to investigate the following characteristics of the ARI: 1 factor structure; 2 internal consistency; 3 construct validity comparing differential relationships between irritability and anxiety dimensions and impairment; and 4 item response theory (IRT parameters. Results: A final Brazilian Portuguese version of the instrument was defined and is presented. Internal consistency was good, and our analysis supported the original single-factor structure of the ARI. Correlations of the ARI with distress-related anxiety dimensions were higher than with phobic-related anxiety dimensions, supporting its construct validity. In addition, higher ARI scores were associated with higher irritability-related impairment. IRT analysis underscored frequency of loss of temper as essential to inform about pathological states of irritability. Conclusion: The Brazilian Portuguese version of the ARI seems to be very similar to the original instrument in terms of conceptual, item, semantic, and operational equivalence. Our preliminary analysis replicates and extends previous evidence confirming promising psychometric properties for the ARI.

    Objective Despite increasing use of the Eating Disorder Examination-Questionnaire (EDE-Q) in bariatric surgery patients, little is known about the utility and psychometric performance of this self-report measure in this clinical group. The primary purpose of the current study was to evaluate the factor structure and construct validity of the EDE-Q in a large series of bariatric surgery candidates. Methods and Procedures Participants were 337 obese bariatric surgery candidates. Participants completed the EDE-Q and a battery of behavioral and psychological measures. Results Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) produced a 12-item, 4-factor structure of the EDE-Q. The four factors, interpreted as Dietary Restraint, Eating Disturbance, Appearance Concerns, and Shape/Weight Overvaluation, were found to be internally consistent and converged with other relevant measures of psychopathology. Discussion Factor analysis of the EDE-Q in bariatric surgery candidates did not replicate the original subscales but revealed an alternative factor structure. Future research must further evaluate the psychometric properties, including the factor structure, of the EDE-Q in this and other diverse populations and consider means of improving this measure's ability to best assess eating-related pathology in bariatric surgery patients.

    Objectives. To evaluate the psychometric properties of the Chinese version of the Patient Perceptions of Empowerment Scale (PPES) and to perform a cross-cultural validity assessment. Methods. In this cross-sectional survey, 554 inpatients in three general hospitals in northern Taiwan were recruited. Principal component analysis was used to examine the factor structure of the scale. Confirmatory factor analyses were conducted on the measurement model of the Chinese version of the PPES. Results. Confirmatory factor analyses supported the presence of a second-order four-factor model (information, decision, individual, and self-management) of the Chinese version of the PPES when used with a Taiwanese inpatient population. The results indicate that the 11-item, second-order, four-factor Chinese version of the PPES provided best goodness-of-fit for the data in this study. Conclusion. The 11-item four-factor Chinese version of the PPES is a self-completion scale. This study demonstrated that the Chinese version of the PPES is a reliable and valid self-report instrument for the assessment of patient perceptions of empowerment in clinical practice. Further adaptation and evaluation of the scale will hopefully stimulate further studies on PPES in the fields of psychometrics in Taiwan. PMID:24971354

    The use of health information technology (HIT) for the support of communication processes and data and information access in acute care settings is a relatively new phenomenon. A means of evaluating the impact of HIT in hospital settings is needed. The purpose of this research was to design and psychometrically evaluate the Impact of Health Information Technology scale (I-HIT). I-HIT was designed to measure the perception of nurses regarding the ways in which HIT influences interdisciplinary communication and workflow patterns and nurses' satisfaction with HIT applications and tools. Content for a 43-item tool was derived from the literature, and supported theoretically by the Coiera model and by nurse informaticists. Internal consistency reliability analysis using Cronbach's alpha was conducted on the 43-item scale to initiate the item reduction process. Items with an item total correlation of less than 0.35 were removed, leaving a total of 29 items. Item analysis, exploratory principal component analysis and internal consistency reliability using Cronbach's alpha were used to confirm the 29-item scale. Principal components analysis with Varimax rotation produced a four-factor solution that explained 58.5% of total variance (general advantages, information tools to support information needs, information tools to support communication needs, and workflow implications). Internal consistency of the total scale was 0.95 and ranged from 0.80-0.89 for four subscales. I-HIT demonstrated psychometric adequacy and is recommended to measure the impact of HIT on nursing practice in acute care settings.

    2010-01-01

    Burnout and work engagement are generally defined as psychological states but the methods used to measure these constructs are more in line with methods used to assess psychological traits. Thus, a new instrument called the Scale of Work Engagement and Burnout (SWEBO) measuring the state mood of burnout and work engagement was developed during the fall of 2007. The purpose of the present study was to evaluate the SWEBO using psychometrical methods. The sample consisted of 2,266 newly graduated Swedish nurses and teachers. Measurement models of both burnout and work engagement were evaluated using confirmatory factor analysis (CFA). Both burnout and work engagement were also tested for measurement invariance across occupation and age. The fit of the measurement model of burnout was satisfactory and it was invariant across both occupation and age. The measurement model of work engagement as initially defined did not fit the data satisfactorily. The model was therefore revised and reanalyzed. The revised model had a satisfactory fit and was invariant across occupation. Analysis of its invariance across age, however, gave ambiguous results that were difficult to interpret. The SWEBO presents a psychometrically sound alternative for measuring burnout and work engagement.

    Self-stigma may feature strongly and be detrimental for people with depression, but the understanding of its nature and prevalence is limited by the lack of psychometrically-validated measures. This study aimed to develop and validate a measure of self-stigma about depression. Items assessing self-stigma were developed from focus group discussions, and were tested and refined over three studies using surveys of 408 university students, 330 members of a depression Internet network, and 1312 members of the general Australian public. Evaluation involved item-level and bivariate analyses, and factor analytic procedures. Items performed consistently across the three surveys. The resulting Self-Stigma of Depression Scale (SSDS) comprised 16 items representing subscales of Shame, Self-Blame, Social Inadequacy, and Help-Seeking Inhibition. Construct validity, internal consistency and test-retest reliability were satisfactory. The SSDS distinguishes self-stigma from perceptions of stigma by others, yields in-depth information about self-stigma of depression, and possesses good psychometric properties. It is a promising tool for the measurement of self-stigma and is likely to be useful in further understanding self-stigma and evaluating stigma interventions.

    Bourke-Taylor, Helen; Pallant, Julie; Cordier, Reinie

    In this article, we evaluate psychometric properties of the Child's Challenging Behaviour Scale, Version 2 (CCBS-2) with mothers of young, typically developing children. A cross-sectional mail survey with Australian mothers (N = 337) included the CCBS-2, the Depression Anxiety Stress Scales, and the Parents' Evaluation of Developmental Status scale. Internal consistency was good, and no gender differences in CCBS-2 scores were significant. Significant results included differences between CCBS-2 scores: among children grouped according to age, among children grouped according to pre- and post-school entry, among mothers grouped according to extent of any symptom type, and between this sample and a previously collected age-matched sample of children with disabilities. Of the properties tested, results support sound psychometrics. The CCBS-2 can be used to differentiate children according to age, school entry, and disability as well as to identify families for potential services in behavior management and mental health.

    The aim of the study is to evaluate the psychometric properties of the Bahasa Melayu version of the Taqwa (piety) questionnaire, used for the measurement of behaviour of Drug Dependency Syndrome (DDS), in Malay patients. A sample of 98 males with a psychiatric diagnosis (DSM-IV-R) as the DDS was randomly selected from Kajang Khafidz Polyclinic Kuala Lumpur, Malaysia. After receiving their agreement to attend the study, they completed the Taqwa (piety) questionnaire. The reliability was assessed by determining the Cronbach's [Formula: see text] to measure the consistency of related questions for all four dimensions (subscales), including individual, social, cognitional, and emotional Taqwa behaviour. In the next step to evaluate the composite reliability, convergent, and discrimination validity, a measurement model was determined via Conformity Factor Analysis (CFA) based on Partial List Square method (Smart- PLS Ver: 2M3). The reliability of four dimensions of the questionnaire was acceptable ([Formula: see text] correlated to each other. However, according to the CFA method, the items with low loading factor (discrimination validity were satisfied in all conformity factor loading that exceeded 0/05. The psychometric properties of the Taqwa questionnaire are acceptable, and the scale is a good instrument for assessing the Islamic attitude, beliefs, and behaviour of the Bahasa Melayu DDS patients.

    Post-conflict Liberia has one of the fastest growing populations on the continent and one of the highest maternal mortality rates among the world. However, in the rural regions, less than half of all births are attended by a skilled birth attendant. There is a need to evaluate the relationship between trained traditional healthcare providers and skilled birth attendants to improve maternal health outcomes. This evaluation must also take into consideration the needs and desires of the patients. The purpose of this pilot study was to establish the validity and reliability of a survey tool to evaluate trust and teamwork in the working relationships between trained traditional midwives and certified midwives in a post-conflict country. A previously established scale, the Trust and Teambuilding Scale, was used with non- and low-literate trained traditional midwives (n=48) in rural Liberia to evaluate trust and teamwork with certified midwives in their communities. Initial results indicated that the scale and response keys were culturally inadequate for this population. A revised version of the scale, the Trust and Teamwork Scale - Liberia, was created and administered to an additional group of non- and low-literate, trained traditional midwives (n=42). Exploratory factor analysis using Mplus for dichotomous variables was used to determine the psychometric properties of the revised scale and was then confirmed with the full sample (n=90). Additional analyses included contrast validity, convergent validity, and Kuder-Richardson reliability. Exploratory factor analysis revealed two factors in the revised Trust and Teamwork Scale - Liberia. These two factors, labeled trust and teamwork, included eleven of the original eighteen items used in the Trust and Teamwork Scale and demonstrated contrast and convergent validity and adequate reliability. The revised scale is suitable for use with non- and low-literate, trained traditional midwives in rural Liberia. Continued cross

    To evaluate the psychometric properties of the Dutch version of the 16-item Subjective Opiate Withdrawal Scale (SOWS). The SOWS measures withdrawal symptoms at the time of assessment. The Dutch SOWS was repeatedly administered to a sample of 272 opioid-dependent inpatients of four addiction treatment centers during rapid detoxification with or without general anesthesia. Examination of the psychometric properties of the SOWS included exploratory factor analysis, internal consistency, test-retest reliability, and criterion validity. Exploratory factor analysis of the SOWS revealed a general pattern of four factors with three items not always clustered in the same factors at different points of measurement. After excluding these items from factor analysis four factors were identified during detoxification (temperature dysregulation, tractus locomotorius, tractus gastro-intestinalis and facial disinhibition). The 13-item SOWS shows high internal consistency and test-retest reliability and good validity at different stages of withdrawal. The 13-item SOWS is a reliable and valid instrument to assess opioid withdrawal during rapid detoxification. Three items were deleted because their content does not correspond directly with opioid withdrawal symptoms. Copyright (c) 2007 S. Karger AG, Basel.

    The objective of the study is to evaluate the psychometric properties of the Gaming Addiction Identification Test (GAIT) and its parent version (GAIT-P), in a representative community sample of adolescents and parents in Västmanland, Sweden. Self-rated and parent-rated gaming addictive symptoms identified by GAIT and GAIT-P were analyzed for frequency of endorsement, internal consistency, concordance, factor structure, prevalence of Internet gaming disorder (IGD), concurrence with the Gaming Addiction Scale for Adolescents, 7-item version (GAS) and the parent version of GAS (GAS-P), and for sex differences. The 12-month prevalence of IGD was found to be 1.3% with GAIT and 2.4% with GAIT-P. Results also indicate promising psychometric results within this population, with high internal consistency, and high concurrent validity with GAS and GAS-P. Concordance between adolescents and parents ratings was high, although moderate in girls. Although exploratory factor analysis indicated poor model fit, it also indicated unidimensionality and high factor loadings in all analyses. GAIT and GAIT-P are suitable for continued use in measuring gaming addiction in adolescents, and, with the additional two items, they now cover all nine IGD criteria. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    To evaluate the psychometric properties of the Spiritual Coping Strategies scale Arabic version (SCS-A) in a sample of nursing students in Saudi Arabia. This study had a cross-sectional design with a convenience sample of 100 nursing students in Saudi Arabia. Using the SCS-A and the Muslim Religiosity Scale for data collection, data were analyzed to establish the reliability and validity of the SCS-A. Good internal consistency reliability (Cronbach's α > .70) and stability reliability (intraclass correlation coefficient > .80) were observed. Two dominant factors were extracted from the scale items, the nonreligious coping strategies and religious coping strategies, which accounted for 35.5% and 32.7% of the variance, respectively. The religious coping subscale exhibited a strong positive correlation with the religious practices subscale of the Muslim Religious Involvement Scale (r = .45, p well as a weak positive correlation with the intrinsic religious beliefs subscale (r = .25, p Scale. The SCS-A exhibited an acceptable validity and reliability, supporting its sound psychometric properties with respect to the responses from Saudi nursing students. © The Author(s) 2016.

    Full Text Available Abstract Background Fast-acting medications for the management of anxiety are important to patients and society. Measuring early onset, however, requires a sensitive and clinically responsive tool. This study evaluates the psychometric properties of a patient-reported Global Anxiety - Visual Analog Scale (GA-VAS. Methods Data from a double-blind, randomized, placebo-controlled study of lorazepam and paroxetine in patients with Generalized Anxiety Disorder were analyzed to assess the reliability, validity, responsiveness, and utility of the GA-VAS. The GA-VAS was completed at clinic visits and at home during the first week of treatment. Targeted psychometric analyses—test-retest reliabilities, validity correlations, responsiveness statistics, and minimum important differences—were conducted. Results The GA-VAS correlates well with other anxiety measures, at Week 4, r = 0.60 (p r = 0.74 (p p p p Conclusions The GA-VAS is capable of validly and effectively capturing a reduction in anxiety as quickly as 24 hours post-dose.

    To psychometrically evaluate the Satisfaction with Life Scale in two cohorts of first-episode psychosis patients in the Danish National Schizophrenia Project and in the Swedish Parachute Project. Four properties of the Satisfaction with Life Scale were examined in the Danish cohort (explorative investigation) and then confirmed in the Swedish cohort: (1) the factor structure; (2) correlations between subscales; (3) internal consistencies of subscales; and (4) main tendencies (arithmetic means) and variations (standard deviations) of subscales. The relations between the Satisfaction with Life Scale and various life conditions were investigated in the Swedish cohort. For both samples, the analysis indicated that the obtained four-dimensional 11-item scale had satisfactory properties. Moderately high scores were obtained in the four subscales: "living," "social relationships," "self and present life" and "work." They correlated positively with each other, the internal consistencies of the subscales were acceptable and the means for the subscales indicated no apparent floor or ceiling effects. The four dimensions obtained seem relevant and presented good face validity. The dimensions were confirmed in the Swedish sample. The Satisfaction with Life Scale shows satisfactory psychometric properties and seems valid and useful among first-episode psychosis patients.

    Objective: To determine some of the neuropsychiatric manifestations of systemic lupus erythematosus (SLE) by applying multimodal neurophysiological and psychometric studies. Patients and methods: Twenty-six SLE patients were evaluated for neurological and psychiatric disorders and compared with 26 healthy controls matched for age, sex, education, and social class. The severity of SLE disease was assessed. Each subject was subjected to the following examinations: laboratory, neurophysiology, magnetic resonance imaging of the brain, transcranial duplex, Modified Mini-mental State Examination, Cognitive Assessment Scale Inventory, Hamilton Depression Scale, and Hamilton Anxiety Scale. Results: The mean age of subjects was 25.9 ± 8.9 years. The most prevalent neurological manifestations were (in order of frequency) anxiety in 17 cases (65.4%), depression in 15 cases (57.7%), headache in 10 cases (38.5%), peripheral neuropathy in 7 cases (26.9%), seizures in 6 cases (23.1%), psychosis in 5 cases (19.2%), dementia in 4 cases (15.4%), radiculopathy in 4 cases (15.4%), myositis in 3 cases (11.5%), and stroke in 2 cases (7.7%). There was a significant affection in amplitude of the ulnar nerve, cognitive function impairment, and electroencephalography changes. There was a significant increased mean velocity and decreased Pulsatility Index of the most studied intracranial vessels in the patients. Conclusion: The use of multimodal neurophysiological, transcranial duplex, and psychometric scales increases the sensitivity for detecting nervous system involvement. PMID:21674025

    To date, very little work has been done on evaluating training in suicide intervention. This study developed and piloted a comprehensive method for evaluating suicide intervention training by applying three studies of immediate training effects on (a) suicide intervention abilities, (b) attitudes to suicide and suicide intervention, and (c) knowledge about suicide. The focus of the evaluation was a broadly used 2-day suicide intervention training program. Changes in suicide intervention abilities were measured by the Suicide Intervention Response Inventory (SIRI) and by performance in simulated suicide intervention situations, scored with the Suicide Intervention Protocol (SIP). Subjects consisted of 19 workshop participants in a pre-post condition and 17 participants in a post-test only condition. Results indicated significant increases in skills in suicide intervention situations. No significant effects were noted on the SIRI. Results from the attitudes and knowledge studies were very preliminary. They are reported here so that others may become aware of the methodology being used and the status of evaluation of the target program. Implications for further research are discussed.

    The aim of this study was to psychometrically evaluate the shortened version of the Spiritual Well-Being Scale (SWBS) in Czech adolescents. A nationally representative sample of 4217 adolescents participated in the 2014 Health Behaviour in School-aged Children survey. The internal consistency of the SWBS was assessed using Cronbach's alpha (α) and Mean Inter-Item Correlation (MIIC) values. The factor structure was evaluated using principal component analyses. After adjustment, our new seven-item version of the scale supports a two-factorial model of the SWBS with satisfactory internal consistency (α = 0.814, MIIC = 0.379). This version of the SWBS is suitable for measuring spiritual well-being in a secularising environment.

    The influence of psychological factors on cigarette dependence often surpasses the direct effects of the nicotine itself. Researcher opinions on the nature and extent of psychological contributors to cigarette dependence vary widely. This study develops and psychometrically tests the Psychological Cigarette Dependence Scale (PCDS) for male smokers in Taiwan. The PCDS was developed using domain identification, individual interviews for item generation, expert reviews, and testing for construct validity and instrument stability. After initial item analysis, the PCDS was tested for concurrent and construct validity and reliability on 256 adult male smokers recruited from community centers, trade and business organizations, private companies, and factories in southern Taiwan. Participants were limited to adult men because female smokers are a small (4.1%) proportion of the female population in Taiwan and thus are difficult to recruit in statistically significant numbers. Exploratory factor analysis showed that lifelong binding and health concerns are the two predominating factors addressed by the 37-item PCDS. The PCDS correlated positively with the Fagerstrom questionnaire (r = .54, p < .01). Cronbach's alpha was .94, and test-retest reliability (intraclass coefficient) was .77 (N = 28). Preliminary evidence suggests that this scale is a valid measure of psychological cigarette dependence. Assessment results may help nursing professionals focus on smoking cessation interventions that are tailored to the patterns and severity of patients' psychological cigarette dependence.

  12. National uranium resource evaluation, preliminary report

    International Nuclear Information System (INIS)

    1976-06-01

    The results of the initial phase of the National Uranium Resource Evaluation (NURE) are reported. NURE is a comprehensive nationwide program to evaluate uranium resources and to identify areas favorable for uranium exploration. Part I presents estimates of uranium ore reserves and potential resources available at costs (not prices) of $10, $15, and $30 per pound U 3 O 8 (uranium oxide). These estimates comprise the national uranium resource position. They are, however, preliminary because limitations of time and available geologic data prevented adequate assessment of some areas that may be favorable for potential resources. Part II presents the potential uranium resources for each of 13 regions, whose boundaries have been drawn chiefly on geologic considerations. The general geology is summarized, and the types of uranium deposits are described. Although limited geologic reconnaissance was done in various parts of the country, the report is based primarily on the compilation and evaluation of data in ERDA files. Mining companies furnished a substantial amount of information on exploration results, development, production, and future plans. Published, manuscript, and open-file reports by government agencies, universities, and research organizations were reviewed. In addition, many individuals affiliated with universities and with state and federal agencies provided supplemental geologic information. This was particularly helpful in the eastern and central states and in Alaska, where information on uranium occurrences is limited

    The main objective of this work is the development and psychometric validation of an instrument to evaluate nurses' adherence to the main recommendations issued for preventing pressure ulcers. An instrument was designed based on the main recommendations for the prevention of pressure ulcers published in various clinical practice guides. Subsequently, it was proceeded to evaluate the face and content validity of the instrument by an expert group. It has been applied to 249 Spanish nurses took part in a cross-sectional study to obtain a psychometric evaluation (reliability and construct validity) of the instrument. The study data were compiled from June 2015 to July 2016. From the results of the psychometric analysis, a final 18-item, 4-factor questionnaire was derived, which explained 60.5% of the variance and presented the following optimal indices of fit (CMIN/DF: 1.40 p < 0.001; GFI: 0.93; NFI: 0.92; CFI: 0.98; TLI: 0.97; RMSEA: 0.04 (90% CI 0.025-0.054). The results obtained show that the instrument presents suitable psychometric properties for evaluating nurses' adherence to recommendations for the prevention of pressure ulcers.

    Significant resources are being invested into eHealth technology to improve health care. Few resources have focused on evaluating the impact of use on patient outcomes A standardized set of metrics used across health systems and research will enable aggregation of data to inform improved implementation, clinical practice, and ultimately health outcomes associated with use of patient-facing eHealth technologies. The objective of this project was to conduct a systematic review to (1) identify existing instruments for eHealth research and implementation evaluation from the patient's point of view, (2) characterize measurement components, and (3) assess psychometrics. Concepts from existing models and published studies of technology use and adoption were identified and used to inform a search strategy. Search terms were broadly categorized as platforms (eg, email), measurement (eg, survey), function/information use (eg, self-management), health care occupations (eg, nurse), and eHealth/telemedicine (eg, mHealth). A computerized database search was conducted through June 2014. Included articles (1) described development of an instrument, or (2) used an instrument that could be traced back to its original publication, or (3) modified an instrument, and (4) with full text in English language, and (5) focused on the patient perspective on technology, including patient preferences and satisfaction, engagement with technology, usability, competency and fluency with technology, computer literacy, and trust in and acceptance of technology. The review was limited to instruments that reported at least one psychometric property. Excluded were investigator-developed measures, disease-specific assessments delivered via technology or telephone (eg, a cancer-coping measure delivered via computer survey), and measures focused primarily on clinician use (eg, the electronic health record). The search strategy yielded 47,320 articles. Following elimination of duplicates and non

    To evaluate the psychometric properties of the D-Catch instrument. A cross-sectional methodological study. Validity and reliability were estimated with confirmatory factor analysis (CFA) and internal consistency and inter-rater reliability, respectively. A sample of 250 nursing documentations was selected. CFA showed the adequacy of a 1-factor model (chronologically descriptive accuracy) with an outlier item (nursing diagnosis accuracy). Internal consistency and inter-rater reliability were adequate. The D-Catch is a valid and reliable instrument for measuring the accuracy of nursing documentation. Caution is needed when measuring diagnostic accuracy since only one item measures this dimension. The D-Catch can be used as an indicator of the accuracy of nursing documentation and the quality of nursing care. © 2015 NANDA International, Inc.

    Full Text Available In this paper the psychometric data of a scale of evaluation of the social abilities (social expression and motor skills are presented. The scale was constructed to investigate social competence and antisocial conduct in adolescence. The process of the scale’s construction is explained; and the data on its internal consistency, its test-retest reliability, and its concurrent validity are presented. The scale was filled out by 325 teachers from different schools in the city of Badajoz (Spain; however, 20 scales were rejected because they were not properly completed. As well, the scale was analyzed, giving as a result 9 factors that explain 59.4% of the total variance. With the results obtained, the position of situational specificity with regard to social abilities is supported.

    The objectives of the present study were to translate and cross-culturally adapt the English version of the Parkinson Fatigue Scale into Turkish, to evaluate its psychometric properties, and to compare them with that of other language versions. A total of 144 patients with idiopathic Parkinson disease were included in the study. The Turkish version of Parkinson Fatigue Scale was evaluated for data quality, scaling assumptions, acceptability, reliability, and validity. The questionnaire response rate was 100% for both test and retest. The percentage of missing data was zero for items, and the percentage of computable scores was full. Floor and ceiling effects were absent. The Parkinson Fatigue Scale provides an acceptable internal consistency (Cronbach's alpha was 0.974 for 1st test and 0.964 for a retest, and corrected item-to-total correlations were ranged from 0.715 to 0.906) and test-retest reliability (Cohen's kappa coefficients were ranged from 0.632 to 0.786 for individuals items, and intraclass correlation coefficient was 0.887 for the overall Parkinson Fatigue Scale Score). An exploratory factor analysis of the items revealed a single factor explaining 71.7% of variance. The goodness-of-fit statistics for the one-factorial confirmatory factor analysis were Tucker Lewis index = 0.961, comparative fit index = 0.971 and root mean square error of approximation = 0.077 for a single factor. The average Parkinson Fatigue Scale Score was correlated significantly with sociodemographic data, clinical characteristics and scores of rating scales. The Turkish version of the Parkinson Fatigue Scale seems to be culturally well adapted and have good psychometric properties. The scale can be used in further studies to assess the fatigue in patients with Parkinson's disease.

    Quality of life is often considered when deciding and evaluating the treatment strategy for patients diagnosed with anal fistula. The purpose of this study was to develop and psychometrically test the Quality of Life in Patients with Anal Fistula Questionnaire. This was an observational cross-sectional study for the development and validation of a psychometric tool. The study was conducted at a general hospital in the southeast of Spain. A convenience sample included 54 patients diagnosed with anal fistula. The reliability of the tool was assessed through its internal consistency (Cronbach α) and temporal stability (Spearman correlation coefficient (r) between test-retest). The content validity index of the items and the scale was calculated. Correlation analysis and an ordinal regression analysis between the developed tool and the Short Form 12 Health Survey examined its concurrent validity. Principal component analysis and known-group analysis using the Kruskal-Wallis test examined its construct validity. The reliability of the developed questionnaire was very high (α = 0.908; r = 0.861; p questionnaire to detect expected differences in patients presenting with different symptomatology. The major limitations of this study were the use of a small sample of Spanish-speaking patients, not including patients in the initial development of the questionnaire, and developing the scoring system using a summation method. The Quality of Life in Patients with Anal Fistula Questionnaire has proven to be a valid, reliable, and concise tool that could contribute to the evaluation of quality of life among patients with an anal fistula.

    The widely used Rosenberg's self-esteem scale (RSES) has not been evaluated for psychometric properties in Sweden. This study aimed at analyzing its factor structure, internal consistency, criterion, convergent and discriminant validity, sensitivity to change, and whether a four-graded Likert-type response scale increased its reliability and validity compared to a yes/no response scale. People with mental illness participating in intervention studies to (1) promote everyday life balance (N = 223) or (2) remedy self-stigma (N = 103) were included. Both samples completed the RSES and questionnaires addressing quality of life and sociodemographic data. Sample 1 also completed instruments chosen to assess convergent and discriminant validity: self-mastery (convergent validity), level of functioning and occupational engagement (discriminant validity). Confirmatory factor analysis (CFA), structural equation modeling, and conventional inferential statistics were used. Based on both samples, the Swedish RSES formed one factor and exhibited high internal consistency (>0.90). The two response scales were equivalent. Criterion validity in relation to quality of life was demonstrated. RSES could distinguish between women and men (women scoring lower) and between diagnostic groups (people with depression scoring lower). Correlations >0.5 with variables chosen to reflect convergent validity and around 0.2 with variables used to address discriminant validity further highlighted the construct validity of RSES. The instrument also showed sensitivity to change. The Swedish RSES exhibited a one-component factor structure and showed good psychometric properties in terms of good internal consistency, criterion, convergent and discriminant validity, and sensitivity to change. The yes/no and the four-graded Likert-type response scales worked equivalently.

    Intuitive eating has been described to represent an adaptive eating behaviour that is characterised by eating in response to physiological hunger and satiety cues, rather than situational and emotional stimuli. The Intuitive Eating Scale-2 (IES-2) has been developed to measure such attitudes and behaviours on four subscales: unconditional permission to eat (UPE), eating for physical rather than emotional reasons (EPR), reliance on internal hunger and satiety cues (RHSC), and body-food choice congruence (B-FCC). The present study aimed at validating the psychometric properties of the German translation of the IES-2 in a large German-speaking sample. A second objective was to assess levels of intuitive eating in participants with an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, or binge eating disorder). The proposed factor structure of the IES-2 could be confirmed for the German translation of the questionnaire. The total score and most subscale scores were negatively related to eating disorder symptomatology, problems in appetite and emotional awareness, body dissatisfaction, and self-objectification. Women with eating disorders had significantly lower values on all IES-2 subscale scores and the total score than women without an eating disorder diagnosis. Women with a binge eating disorder (BED) diagnosis had higher scores on the UPE subscale compared to participants with anorexia nervosa (AN) or bulimia nervosa (BN), and those diagnosed with AN had higher scores on the EPR subscale than individuals with BN or BED. We conclude that the German IES-2 constitutes a useful self-report instrument for the assessment of intuitive eating in German-speaking samples. Further studies are warranted to evaluate psychometric properties of the IES-2 in different samples, and to investigate its application in a clinical setting. Copyright © 2016 Elsevier Ltd.

    Measurement of consumers' satisfaction in psychiatric settings is important because it has been correlated with improved clinical outcomes and administrative measures of high-quality care. These consumer satisfaction measurements are actively used as performance measures required by the accreditation process and for quality improvement activities. Our objectives were (i) to re-evaluate, through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), the structure of an instrument intended to measure consumers' satisfaction with care in psychiatric settings and (ii) to examine and publish the psychometric characteristics, validity and reliability, of the Inpatient Consumer Survey (ICS). To psychometrically test the structure of the ICS, 34 878 survey results, submitted by 90 psychiatric hospitals in 2008, were extracted from the Behavioral Healthcare Performance Measurement System (BHPMS). Basic descriptive item-response and correlation analyses were performed for total surveys. Two datasets were randomly created for analysis. A random sample of 8229 survey results was used for EFA. Another random sample of 8261 consumer survey results was used for CFA. This same sample was used to perform validity and reliability analyses. The item-response analysis showed that the mean range for a disagree/agree five-point scale was 3.10-3.94. Correlation analysis showed a strong relationship between items. Six domains (dignity, rights, environment, empowerment, participation, and outcome) with internal reliabilities between good to moderate (0.87-0.73) were shown to be related to overall care satisfaction. Overall reliability for the instrument was excellent (0.94). Results from CFA provided support for the domains structure of the ICS proposed through EFA. The overall findings from this study provide evidence that the ICS is a reliable measure of consumer satisfaction in psychiatric inpatient settings. The analysis has shown the ICS to provide valid and

    Pain-related stoicism and cautiousness are theorized to be more prevalent in older than younger patients and to lead to greater pain under-reporting and consequently inadequate pain management in older patients. The Pain Attitudes Questionnaire-Revised (PAQ-R), which measures 5 pain-related stoicism (fortitude, concealment, superiority) and cautiousness (self-doubt, reluctance) factors in chronic pain, can help test this hypothesis in advanced cancer but requires validation. We conducted a psychometric evaluation of the PAQ-R in 155 younger (younger than 60 years) and 114 older (aged 60 years and older) patients with advanced cancer. Participants showed disagreement with self-doubt items and floor effects with the subscale. Confirmatory factor analyses revealed good fit of the PAQ-R's 5 factors to younger and older groups' data but collinearity between fortitude and concealment. Multisample confirmatory factor analyses supported partial scalar invariance between age groups. Few hypothesized age-related differences were observed. Younger patients reported higher superiority scores than older patients. Whereas older patients showed greater fortitude and superiority with lower average pain intensity, younger patients showed greater concealment or fortitude with greater worst and average pain intensity. Furthermore, whereas older patients displayed greater superiority with lower interference in relations with others, younger patients displayed greater concealment and superiority with greater interference in walking ability and greater concealment and self-doubt with more interference in relations with others. Cross-validation of the PAQ-R's factor structure and identification of pathways to the factors and effect on pain-related outcomes using multivariate approaches are warranted. This article presents the psychometric properties of a measure of 2 particular pain-related attitudes. The measure can help clarify whether these attitudes adversely influence pain

    To develop and evaluate a new instrument that measures unique aspects of long-term survivorship for people diagnosed with cancer as Adolescent and Young Adult (AYA), not measured by existing tools. A new candidate instrument-the Impact of Cancer for Adolescent and Young Adult (IOC-AYA) cancer survivors-was developed and administered to AYA cancer survivors aged 18-35 years who were 15-29 years old when diagnosed with cancer. Psychometric properties of newly derived scales were assessed. Factor analyses of items derived seven new and specific subscales: Social Life; Uncertainties, Worries and Wonders; Cognitive Function; Sense of Purpose/Life Goals; Identity; Health Behaviors; and Health Literacy. Two separate and conditional subscales were formed: Relationship Concerns (partnered/unpartnered) and Having Children (at least one child/no children). Internal consistency measurements for these subscales ranged from 0.70 to 0.90. Expected associations within and among IOC-AYA subscales and standardized measures of quality of life were observed. Psychometric analyses indicated that this initial version of the IOC-AYA measures distinct and relevant constructs for survivors diagnosed with cancer in adolescence and young adulthood. Future work is needed to confirm the responsiveness to change and further validate the instrument in multiple and representative samples. Use of the IOC-AYA instrument in research and clinical practice will inform the development of psychosocial and supportive care interventions that not only minimize or prevent long-term deleterious effects of cancer but also promote positive adaptation, resilience, and the achievement of age-specific developmental tasks.

    All nurses care for patients with pain, and pain management knowledge and attitude surveys for nurses have been around since 1987. However, no validated knowledge test exists to measure postlicensure clinicians' knowledge of the core competencies of pain management in current complex patient populations. To develop and test the psychometric properties of an instrument designed to measure pain management knowledge of postlicensure nurses. Psychometric instrument validation. Four large Midwestern U.S. hospitals. Registered nurses employed full time and part time August 2015 to April 2016, aged M = 43.25 years; time as RN, M = 16.13 years. Prospective survey design using e-mail to invite nurses to take an electronic multiple choice pain knowledge test. Content validity of initial 36-item test "very good" (95.1% agreement). Completed tests that met analysis criteria, N = 747. Mean initial test score, 69.4% correct (range 27.8-97.2). After revision/removal of 13 unacceptable questions, mean test score was 50.4% correct (range 8.7-82.6). Initial test item percent difficulty range was 15.2%-98.1%; discrimination values range, 0.03-0.50; final test item percent difficulty range, 17.6%-91.1%, discrimination values range, -0.04 to 1.04. Split-half reliability final test was 0.66. A high decision consistency reliability was identified, with test cut-score of 75%. The final 23-item Clinical Pain Knowledge Test has acceptable discrimination, difficulty, decision consistency, reliability, and validity in the general clinical inpatient nurse population. This instrument will be useful in assessing pain management knowledge of clinical nurses to determine gaps in education, evaluate knowledge after pain management education, and measure research outcomes.

    To psychometrically test the London Measure of Unplanned Pregnancy and compare it with the Swedish Pregnancy Planning Scale. The incidence of unplanned pregnancies is an important indicator of reproductive health. The London Measure of Unplanned Pregnancy measures pregnancy planning by taking contraceptive use, timing, intention to become pregnant, desire for pregnancy, partner agreement, and pre-conceptual preparations into account. It has, however, previously not been psychometrically evaluated using confirmatory factor analysis. The Likert-scored single-item Swedish Pregnancy Planning Scale has been developed to measure the woman's own view of pregnancy planning level. Cross-sectional design. In 2012-2013, 5493 pregnant women living in Sweden were invited to participate in the Swedish Pregnancy Planning study, of whom 3327 (61%) agreed to participate and answered a questionnaire. A test-retest pilot study was conducted in 2011-2012. Thirty-two participants responded to the questionnaire on two occasions 14 days apart. Data were analysed using confirmatory factor analysis, Cohen's weighted kappa and Spearman's correlation. All items of the London Measure of Unplanned Pregnancy contributed to measuring pregnancy planning, but four items had low item-reliability. The London Measure of Unplanned Pregnancy and Swedish Pregnancy Planning Scale corresponded reasonably well with each other and both showed good test-retest reliability. The London Measure of Unplanned Pregnancy may benefit from item reduction and its usefulness may be questioned. The Swedish Pregnancy Planning Scale is time-efficient and shows acceptable reliability and construct validity, which makes it more useful for measuring pregnancy planning. © 2017 John Wiley & Sons Ltd.

    Full Text Available Abstract Objective The s allele of the 5-hydroxytryptamine transporter-linked promoter region (5-HTTLPR polymorphism of the serotonin transporter gene has been found to be associated with neuroticism-related traits, affective temperaments and response to selective serotonin reuptake inhibitor (SSRI treatment. The aim of the current study was to develop a psychometric tool that could at least partially substitute for laboratory testing and could predict the presence of the s allele. Methods The study included 138 women of Caucasian origin, mean 32.20 ± 1.02 years old. All subjects completed the Hungarian standardised version of the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A instrument and were genotyped for 5-HTTLPR using PCR. The statistical analysis included the calculation of the Index of Discrimination (D, Discriminant Function Analysis, creation of scales on the basis of the above and then item analysis and calculation of sensitivity and specificity. Results Four indices were eventually developed, but their psychometric properties were relatively poor and their joint application did not improve the outcome. Conclusions We could not create a scale that predicts the 5-HTTLPR genotype with sufficient sensitivity and specificity, therefore we could not substitute a psychometric scale for laboratory genetic testing in predicting genotype, and also possibly affective disorder characterisation and treatment.

    The rate of concussions in adolescents has risen over the last decade, resulting in cognitive and emotional problems. Neurologists recommend cognitive and physical rest during the recovery period, followed by a transitional return-to-classroom protocol. The purpose of the study was to develop and test an instrument that explores the beliefs and roles of school nurses in concussion care management. The instrument was a cross-sectional descriptive survey based on the theory of planned behavior, using Qualtrics®. The psychometric properties of the instrument were assessed through exploratory factor analysis with orthogonal rotation. The reliability of the instrument was assessed for internal consistency reliability using Cronbach's α. Kaiser-Meyer-Olkin for sample adequacy was .8; Cronbach's α strong (.851).

    The objective of this study was to evaluate the validity of the Heartburn Reflux Dyspepsia Questionnaire (HRDQ), a newly developed measure of gastro-oesophageal reflux disease (GORD) symptoms. Specifically, the HRDQ was developed for patients, who still experience symptoms with proton pump inhibitor (PPI) treatment. The psychometric properties of HRDQ were evaluated based on data from two clinical trials of patients with GORD with a partial response to PPIs, one from the UK and one from Denmark and Germany. The HRDQ had good internal consistency (Cronbach's alpha range .83-.88) and test-retest reliability (intraclass correlation coefficient range .71-.90). Convergent and discriminant validity were supported by high correlations with ReQuest™ and ability to differentiate between groups based on ReQuest™ cut-off values. Responsiveness of HRDQ was demonstrated by moderate to high correlations with ReQuest™ change scores and time with symptoms. An HRDQ cut-off value of 0.70 for definition of 'bad day' was also evaluated. Based on existing evidence, the HRDQ is a valid and reliable measure of GORD symptoms that can be used as a study outcome in clinical trials.

    2016-01-01

    The Profile of Music Perception Skills (PROMS) is a recently developed measure of perceptual music skills which has been shown to have promising psychometric properties. In this paper we extend the evaluation of its brief version to three kinds of validity using an individual difference approach. The brief PROMS displays good discriminant validity with working memory, given that it does not correlate with backward digit span (r = .04). Moreover, it shows promising criterion validity (association with musical training (r = .45), musicianship status (r = .48), and self-rated musical talent (r = .51)). Finally, its convergent validity, i.e. relation to an unrelated measure of music perception skills, was assessed by correlating the brief PROMS to harmonic closure judgment accuracy. Two independent samples point to good convergent validity of the brief PROMS (r = .36; r = .40). The same association is still significant in one of the samples when including self-reported music skill in a partial correlation (rpartial = .30; rpartial = .17). Overall, the results show that the brief version of the PROMS displays a very good pattern of construct validity. Especially its tuning subtest stands out as a valuable part for music skill evaluations in Western samples. We conclude by briefly discussing the choice faced by music cognition researchers between different musical aptitude measures of which the brief PROMS is a well evaluated example.

    Informed by our research on student understanding of cosmology, The Big Ideas in Cosmology is an immersive set of web-based learning modules that integrates text, figures, and visualizations with short and long interactive tasks and real cosmological data. This enables the transformation of general education astronomy and cosmology classes from primarily lecture and book-based courses to a more engaging format that builds important STEM skills.During the spring 2014 semester, we field-tested a subset of chapters with the general education astronomy and cosmology classes at Sonoma State University in a flipped-classroom format. We administered pre and post content and attitude assessments in the two flipped classes as well as two lecture classes. The majority of cosmology students had taken astronomy before whereas the astronomy students had not.When switching to an active mode of learning (e.g., flipped classroom instead of lecture), many instructors report pushback from students. We saw this effect from students in course evaluations, who reported dissatisfaction with "having to do more work." However, the students in the flipped section in astronomy made greater gains on the multiple choice content assessment than the students in either of the two lecture sections. On the attitude assessment (the CLASS), the cosmology students made a small shift toward more expert-like opinions. Preliminary results from open-ended content surveys indicate that, prior to instruction, students had difficulty answering 'why' or 'how do we know' questions; that post-instruction, students are less likely to respond "I don't know" or to leave an answer blank; and that students using the modules made gains in their content knowledge.Module development was supported by NASA ROSES E/PO Grant #NNXl0AC89G, the Illinois Space Grant Consortium, the Fermi E/PO program, Sonoma State University's Space Science Education and Public Outreach Group, and Great River Technology

The Nighttime Symptoms of COPD Instrument (NiSCI was designed to measure the occurrence and severity of nighttime symptoms in patients with COPD, the impact of symptoms on nighttime awakenings, and rescue medication use. The objective of this study was to explore item reduction, inform scoring recommendations, and evaluate the psychometric properties of the NiSCI.Methods: COPD patients participating in a Phase III clinical trial completed the NiSCI daily. Item analyses were conducted using weekly mean and single day scores. Descriptive statistics (including percentage of respondents at floor/ceiling and inter-item correlations, factor analyses, and Rasch model analyses were conducted to examine item performance and scoring. Test–retest reliability was assessed for the final instrument using the intraclass correlation coefficient (ICC. Correlations with assessments conducted during study visits were used to evaluate convergent and known-groups validity.Results: Data from 1,663 COPD patients aged 40–93 years were analyzed. Item analyses supported the generation of four scores. A one-factor structure was confirmed with factor analysis and Rasch analysis for the symptom severity score. Test–retest reliability was confirmed for the six-item symptom severity (ICC, 0.85, number of nighttime awakenings (ICC, 0.82, and rescue medication (ICC, 0.68 scores.

    Perceptions of exercise benefits and barriers affect exercise behavior. Because of the clinical course and treatment, dialysis patients differ from the general population in their perceptions of exercise benefits and barriers, especially the latter. At present, no valid instruments for assessing perceived exercise benefits and barriers in dialysis patients are available. Our goal was to develop and test the psychometric properties of the Dialysis patient-perceived Exercise Benefits and Barriers Scale (DPEBBS). A literature review and two focus groups were conducted to generate the initial item pool. An expert panel examined the content validity. Then, 269 Chinese hemodialysis patients were recruited by convenience sampling. Exploratory and confirmatory factor analyses were used to test construct validity. Finally, internal consistency and test-retest reliability were assessed. The expert panel determined that the content validity index was satisfactory. The final 24-item scale consisted of six factors explaining 57% of the total variance in the data. Confirmative factor analysis supported the six-factor structure and a higher-order model. Cronbach's alpha was 0.87 for the total scale, and 0.84 for test-retest reliability. The DPEBBS was a valid and reliable instrument for evaluating dialysis patients' perceived benefits and barriers to exercise. The application value of this scale remains to be investigated by increasing the sample size and evaluating patients undergoing different dialysis modalities and coming from different regions and cultural backgrounds.

    This study evaluated the psychometric properties of the Youth Eating Disorder Examination Questionnaire (YEDE-Q) and its utility for detecting loss of control (LOC) eating (i.e., eating episodes, regardless of size, involving a perceived inability to control what or how much one is eating) among school-age children with overweight or obesity. Identifying eating pathology, particularly LOC eating, in this population may facilitate treatment that improves weight outcomes and reduces eating disorder risk. Children with overweight or obesity (N = 241; 7-11 years) completed the YEDE-Q and abbreviated Child EDE (ChEDE) to assess LOC eating, prior to entering a weight management treatment trial. Confirmatory factor analyses (CFA) were conducted on children's YEDE-Q responses and compared to the standard adult EDE-Q factor structure and newer, alternate factor structures. CFA supported a three-factor structure, which distinguished youth with versus without LOC. The YEDE-Q showed low accuracy for detecting LOC eating as measured by the ChEDE, which served as the gold-standard benchmark (AUC = 0.69). Among children who endorsed LOC eating, more episodes per month were reported on the YEDE-Q than ChEDE (p children with overweight or obesity. Further evaluation of the YEDE-Q and the alternate three-factor structure is warranted. © 2017 Wiley Periodicals, Inc.

    To evaluate the psychometric properties of questions that assess patient perceptions of patient-provider communication and design measures of patient-centered communication (PCC). Participants (adults with colon or rectal cancer living in North Carolina) completed a survey at 2 to 3 months post-diagnosis. The survey included 87 questions in six PCC Functions: Exchanging Information, Fostering Health Relationships, Making Decisions, Responding to Emotions, Enabling Patient Self-Management, and Managing Uncertainty. For each Function we conducted factor analyses, item response theory modeling, and tests for differential item functioning, and assessed reliability and construct validity. Participants included 501 respondents; 46% had a high school education or less. Reliability within each Function ranged from 0.90 to 0.96. The PCC-Ca-36 (36-question survey; reliability=0.94) and PCC-Ca-6 (6-question survey; reliability=0.92) measures differentiated between individuals with poor and good health (i.e., known-groups validity) and were highly correlated with the HINTS communication scale (i.e., convergent validity). This study provides theory-grounded PCC measures found to be reliable and valid in colorectal cancer patients in North Carolina. Future work should evaluate measure validity over time and in other cancer populations. The PCC-Ca-36 and PCC-Ca-6 measures may be used for surveillance, intervention research, and quality improvement initiatives. Copyright © 2017 The Authors. Published by Elsevier B.V.

    Self-reflection (also known as reflection) is an internal process that is difficult to perceive or assess. An instrument that is able to measure self-reflection may serve as a resource for educators to assess the learning process of students and to tailor education approaches to student needs. The aim of this study was to translate the Self-Reflection and Insight Scale (SRIS) into Chinese and evaluate its psychometric properties for use with Taiwanese nursing students. For this cross-sectional study, nursing students were recruited from two nursing schools in southern Taiwan in two phases: Phase 1, which included 361 fourth-year students, and Phase 2, which included 703 fifth-year students. Data were collected in December 2012 and May 2013 using the Chinese version of the SRIS (SRIS-C), Taiwan Critical Thinking Disposition Inventory, and the Perceived Identity as a Nurse Questionnaire, which was developed by the author. In Phase 1, exploratory factor analysis was used to explore the factor structure of the SRIS-C in the fourth-year student participants. In Phase 2, confirmatory factor analysis was used to determine the fitness of the model for the fifth-year student participants. Eight items were deleted from the original SRIS to create the SRIS-C. Thus, the Chinese-version measure had 12 items and two factors (self-reflection and insight) that fit the data well. The Cronbach's alpha coefficients for the total scale and its two subscales were .79, .87, and .83, respectively. The 3-week test-retest reliability was .74. SRIS-C scores correlated significantly with scores on the Taiwan Critical Thinking Disposition Inventory and the Perceived Identity as a Nurse Questionnaire, indicating good convergent validity for the SRIS-C. The current study showed that the SRIS-C has sound psychometric properties. This instrument provides nurse educators with information that may be used to evaluate the self-reflection and insight of students and to develop interventions to

    Modern healthcare institutions are continuously changing, and Self-Directed Learning (SDL) abilities are considered a prerequisite for both nursing students and nurses in order to be proactive about these demanding challenges. To date, no systematic reviews of existing instruments aimed at detecting and critically evaluating SDL abilities have been published. Therefore, the aims of this review are: 1) identify the instruments for assessment of SDL abilities among nursing students and nurses; 2) critically evaluate the methodological studies quality; and 3) compare the psychometric properties of the available instruments. A psychometric-systematic-review was performed. CDSR, CINAHL, ERIC, MEDLINE, PROSPERO, SCOPUS databases were searched without restrictions in time and setting. All primary studies involving nursing students or nurses, written in English and aimed at validating SDL assessment tools, were included. Studies retrieved were evaluated according to the COnsensus-based-Standards for the selection of health Measurement-INstruments (COSMIN) panel. Study inclusion, data extraction and quality assessment were performed by researchers independently. Eleven studies were included and four tools based on Knowles's theory have emerged: 1) the Self-Directed Learning Readiness Scale; 2) the Self-Directed Learning Readiness Scale for Nursing Education; 3) the Self-Rating Scale of Self-Directed Learning, and 4) the Self-Directed Learning Instrument. A few psychometric properties have been considered in each study, from two to four out of the ten required. The quality of the methodologies used was in general, from fair to poor with the exception of one instrument (the Self-Directed-Learning-Instrument). The psychometric proprieties that emerged across the tools were good in general: the Cronbach α was from 0.73 to 0.91; structural validities have also reported good indexes both in the explorative and in the confirmative factor analyses.

    To develop a Meaning in Life Scale for cancer patients in Chinese version and to test the validity and reliability. Meaning in life is a protective factor of psychological well-being and is negatively related to depression and demoralisation among cancer patients. The existing scales measuring meaning in life are mostly designed in English and there is no scale designed for Chinese cancer patients based on Chinese cultural background. Process of instrument development and psychometric evaluation were used. Items were generated from literature review and a focus group interview. Delphi technique was used to test the content validity. Item analysis and exploratory factor analysis were performed with data from 251 cancer patients. The internal consistency of the scale was tested by Cronbach's alpha. A 25-item Meaning in Life Scale in Chinese version with five domains was developed. The five factors explained 62·686% of the variance. The Cronbach's alpha for the total scale was 0·897. The Meaning in Life Scale in Chinese version has acceptable internal consistency reliability and good content validity and acceptable construct validity. The content of the scale reflected the attitudes of cancer patients towards meaning in life based on Chinese cultural background. The Chinese version of Meaning in Life Scale for Cancer Patients appears to be a new scale to assess meaning in life among Chinese cancer patients exactly and the concept of meaning in life presented in this scale provides new ideas of meaning intervention in routine clinical practice. © 2016 John Wiley & Sons Ltd.

    The purpose of this study was to determine whether the muscle appearance satisfaction scale (MASS) shows acceptable psychometric properties in Mexican bodybuilders. A total of 258 Mexican male bodybuilders were recruited. Two self-report questionnaires, including the MASS and drive for muscularity scale (DMS), were administered. Six models of the latent structure of the MASS were evaluated, using confirmatory factor analysis with maximum likelihood, considering robust Satorra-Bentler correction to estimate the fit of the models to the data. Similar to the original MASS, the series of CFA confirmed that the Mexican version was well represented with the 17-item five-factor structure, which showed a good model fit [Satorra-Bentler Chi-square (109, n = 258) = 189.18, p McDonald's omega, which was acceptable for the MASS (0.88), and their subscales (0.80 to 0.89), except for muscle checking scale (0.77). Test-retest reliability analysis showed stability of the MASS total as well as of the subscale scores over a 2-week period (intraclass correlation coefficients = 0.75-0.91). Construct validity was demonstrated by a significant positive correlation between MASS and DMS results (r = 0.75; p = 0.0001). These results were similar to those of previous studies, which demonstrate the scale's usefulness. Our results support the suitability of the MASS and its subscales to measure muscle dysmorphia symptoms in Mexican male bodybuilders.

    Parents who are overwhelmed by the intensity and aversive nature of child negative affect - those who are experiencing flooding - may be less likely to react effectively and instead may focus on escaping the aversive situation, disciplining either overly permissively or punitively to escape quickly from child negative affect. However, there are no validated self-report measures of the degree to which parents experience flooding, impeding the exploration of these relations. Thus, we created and evaluated the Parent Flooding scale (PFS), assessing the extent to which parents believe their children's negative affect during parent-child conflicts is unexpected, overwhelming and distressing. We studied its factorial validity, reliability, and concurrent validity in a community sample of 453 couples with 3- to 7-year-old children (51.9 % girls) recruited via random digit dialing. Confirmatory factor analyses indicated a one-factor solution with excellent internal consistency. Test-retest stability over an average of 5.6 months was high. Concurrent validity was suggested by the associations of flooding with parents' aggression toward their children, overreactive and lax discipline, parenting satisfaction, and parents' anger, as well as with child externalizing behavior and negative affect. Incrementally concurrent validity analyses indicated that flooding was a unique predictor of mothers' and fathers' overreactive discipline and fathers' parent-child aggression and lax discipline, over and above the contributions of parents' anger and children's negative affect. The present results support the psychometric validity of the PFS.

    Documentation of clinical outcomes is increasingly expected in delivery of prosthetic services and devices. However, many outcome measures suitable for use in clinical care and research have not been psychometrically tested with prosthesis users. The aim of this study was to determine test-retest reliability, mode-of-administration (MoA) equivalence, standard error of measurement (SEM), and minimal detectable change (MDC) of standardized, self-report instruments that assess constructs of importance to people with lower limb loss. Prosthesis users (n = 201) were randomly assigned to groups based on MoA (i.e., paper, electronic, or mixed-mode). Participants completed two surveys 2 to 3 d apart. Instruments included the Prosthetic Limb Users Survey of Mobility, Prosthesis Evaluation Questionnaire-Mobility Subscale, Activities-Specific Balance Confidence Scale, Quality of Life in Neurological Conditions-Applied Cognition/General Concerns, Patient-Reported Outcomes Measurement Information System Profile, and Socket Comfort Score. Intraclass correlation coefficients indicated all instruments are appropriate for group-level comparisons and select instruments are suitable for individual-level applications. Several instruments showed evidence of possible floor and ceiling effects. All were equivalent across MoAs. SEM and MDC were quantified to facilitate interpretation of outcomes and change scores. These results can enhance clinicians' and researchers' ability to select, apply, and interpret scores from instruments administered to prosthesis users.

Method: Internal consistency reliability was measured using Cronbach's α coefficient and inter-item correlation. Test-retest was performed to examine the instrument's stability. Exploratory principal component analysis (PCA with oblimin rotation was carried out to evaluate construct validity. Finally, the score on each item of the TCT was correlated with the person's Mini Mental State Examination (MMSE and Barthel Index of activities of daily living scores. Results: A total of 51 persons participated, with a mean age of 86.7 (SD 6.6 years, of whom 46 were women with moderate-to-severe dementia [mean MMSE score 7.5 (SD 6.7]. There were two measurement points 2 weeks apart. The results showed a satisfactory level for internal consistency and a high test-retest reliability (r = 0.76. The corrected item-total correlation ranged between 0.50 and 0.87, and a two-factor structure was revealed at the PCA. ‘Vocalizing' seemed to measure another aspect of communication and was the only item which was negatively loaded. Conclusion: Despite the low sample size in this study, the results revealed the TCT as a reliable and valid instrument, suitable for measuring communication among people with dementia. We suggest clarifying the understanding of ‘vocalizing' before considering removing it from the scale.

    To prepare future nurses who can deliver high quality nursing care to teen mothers, a better understanding of the nursing students' perception of teen mothers is needed. A descriptive cross-sectional study was conducted among 228 nursing students to evaluate the psychometric properties of the Positivity Toward Teen Mothers (PTTM) scale, to explore nursing students' general empathy and attitudes toward teen mothers, and to investigate the predictors of nursing students' attitudes toward teen mothers. Principal component factor analysis with varimax rotation resulted in a 19-item PTTM-Revised scale with Non-judgmental and Supportive subscales. Cronbach's alphas for the subscales were 0.84 and 0.69, respectively, and 0.87 for the total scale. Simultaneous multiple regression models showed that general empathy and having a teen mother in the family or as an acquaintance were significant predictors of positive attitudes toward teen mothers, whereas age was a significant negative predictor. The PTTM-Revised scale is a promising instrument for assessing attitudes toward teen mothers. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The purpose of this study is to develop and evaluate the psychometric properties of the Chinese version of short-form Test of Functional Health Literacy in Adolescents. Assessing health literacy is vital to design health education programme; however, there are no measurement tools exist for use specifically in Chinese adolescents. A non-experimental design was used to test the psychometric properties of the Test of Functional Health Literacy in Adolescents. The short-form Test of Functional Health Literacy in Adolescents was translated and back translated into a Chinese language version. Thirty high school students were recruited to validate the scenario of Test of Functional Health Literacy in Adolescents. Based on the multiple-stage stratified random sampling method, 300 high school students from four counties in Taiwan were invited to participate in this study to evaluate the psychometric properties of Test of Functional Health Literacy in Adolescents. The Functional Health Literacy in Adolescents had good internal consistency reliability and excellent test-retest reliability. Confirmatory factor analysis resulted in a one-factor solution. Contrary to the original version of the Test of Functional Health Literacy in Adolescents, the findings revealed that the 36-item, one-factor model for the Test of Functional Health Literacy in Adolescents is the best-fit model. This is a suitable instrument to assess health literacy levels in Chinese adolescents before health education programmes can be appropriately planned, implemented and evaluated. © 2012 Blackwell Publishing Ltd.

    The CES-D is a commonly used self-report assessment for depressive symptomatology. However, its psychometric properties have not been evaluated in Fiji. This study aims to evaluate the reliability and validity of English language and Fijian vernacular versions in ethnic Fijian adolescent schoolgirls. As part of the HEALTHY Fiji study, ethnic Fijian female adolescents (N = 523) completed the CES-D. Participants selected to respond in English or the local vernacular. Reliability (internal consistency, item-total score correlation, and test-retest estimates), validity (associations with other proxies for depression) and factor structure were assessed. Evaluations considered differences between language versions. In this sample, the CES-D had a Cronbach's α of 0.81 and item-total score correlation coefficients ranged between 0.2 and 0.63. One week test-retest reliability (ICC(2)) was 0.57. CES-D scores were higher among individuals who endorsed feelings of depression and suicidality compared to those who did not. ROC analyses of the CES-D versus binary depression and suicidality variables produced AUCs around 0.70 and did not support a discrete cut-off for significant disturbance. Findings were similar across the two language groups. The CES-D has acceptable reliability and validity among ethnic Fijian female adolescents in English and in the Fijian vernacular language. Findings support its utility as a dimensional measure for depressive symptomatology in this study population. Further examination of its clinical utility for case finding for depression in Fijian school-based and community populations is warranted. © The Author(s) 2013.

    Nighttime symptoms can negatively impact the quality of life of patients with chronic obstructive pulmonary disease (COPD). The Nighttime Symptoms of COPD Instrument (NiSCI) was designed to measure the occurrence and severity of nighttime symptoms in patients with COPD, the impact of symptoms on nighttime awakenings, and rescue medication use. The objective of this study was to explore item reduction, inform scoring recommendations, and evaluate the psychometric properties of the NiSCI. COPD patients participating in a Phase III clinical trial completed the NiSCI daily. Item analyses were conducted using weekly mean and single day scores. Descriptive statistics (including percentage of respondents at floor/ceiling and inter-item correlations), factor analyses, and Rasch model analyses were conducted to examine item performance and scoring. Test-retest reliability was assessed for the final instrument using the intraclass correlation coefficient (ICC). Correlations with assessments conducted during study visits were used to evaluate convergent and known-groups validity. Data from 1,663 COPD patients aged 40-93 years were analyzed. Item analyses supported the generation of four scores. A one-factor structure was confirmed with factor analysis and Rasch analysis for the symptom severity score. Test-retest reliability was confirmed for the six-item symptom severity (ICC, 0.85), number of nighttime awakenings (ICC, 0.82), and rescue medication (ICC, 0.68) scores. Convergent validity was supported by significant correlations between the NiSCI, St George's Respiratory Questionnaire, and Exacerbations of Chronic Obstructive Pulmonary Disease Tool-Respiratory Symptoms scores. The results suggest that the NiSCI can be used to determine the severity of nighttime COPD symptoms, the number of nighttime awakenings due to COPD symptoms, and the nighttime use of rescue medication. The NiSCI is a reliable and valid instrument to evaluate these concepts in COPD patients in clinical

    Full Text Available Abstract Background Despite the achievements of previous research, caregiving assessments in severe mental illness should be crossculturally validated in order to define risk groups or to evaluate family work. This study reports on the psychometric properties of the European version of the Involvement Evaluation Questionnaire (IEQ-EU in Portugal. Methods A Portuguese translation of the IEQ-EU was developed according to the 'European Psychiatric Services: Inputs Linked to Outcome Domains and Needs' (EPSILON group guidelines. We then studied 194 caregivers who were related to patients with schizophrenia spectrum disorders in psychiatric outpatient services. All relatives were assessed using the IEQ-EU. In order to describe the corresponding patients' sample, the majority (n = 162 was evaluated with the World Health Organization Disability Assessment Schedule (WHO-DAS II; 108 patients were also assessed with the Brief Psychiatric Rating Scale (BPRS and the Global Assessment of Functioning (GAF. Results The factor structure of the Portuguese version of the questionnaire was similar to the original; internal consistency was good, with Cronbach's α ranging from 0.71 to 0.87 in the IEQ-EU scales (total score and domains: tension, supervision, worrying, urging; test-retest reliability yielded intraclass correlation coefficients (ICCs from 0.80 to 0.94, concerning the same scores. Ecological validity was confirmed. Most caregiving consequences were reported on the worrying domain of the IEQ-EU. Conclusions Validity and reliability of the Portuguese IEQ-EU translation were established. Specifically the four IEQ-EU subscale domains seem to be valid in Portugal.

    This article looks at a means of objectively evaluating the quality of psychometric tests. This approach enables users to evaluate psychometric tests based on their methodological characteristics, in order to decide which instrument should be used. Reading and spelling assessment tools serve as examples. The paper also provides a review of German psychometric tests for the assessment of reading and spelling skills. This method facilitates the identification of psychometric tests.of high methodological quality which can be used for the assessment of reading and spelling skills. Reading performance should ideally be assessed with the following instruments: ELFE 1-6, LGVT 6-12, LESEN 6-7, LESEN 8-9, or WLLP-R. The tests to be used for the evaluation of spelling skills are DERET 1-2+, DERET 3-4+, WRT 1+, WRT 2+, WRT 3+, WRT 4+ or HSP 1-10.

    2016-01-01

    The study sought to develop and evaluate the psychometric properties of the Parental Attitudes Toward Firearms Survey (PATFS), a self-report measure of parental attitudes about firearms and parenting behavior. The initial item pool was generated based on a literature review and discussion with experts in violence reduction, psychometrics, and public health. Data were collected online from 362 volunteers and subjected to exploratory factor analysis which revealed a 13-item, 3-factor solution accounting for 59.7% of the variance. The 3 conceptual factors (subscales) were interpreted as Firearms Exposure, Parental Control, and Violent Play. The PATFS demonstrated good internal consistency and content and construct validity. The PATFS can be used to investigate parenting attitudes and behaviors specific to firearms and violent play.

    Women's experiences of their bodies during pregnancy may reflect their reactions to concrete physical changes as well as self-representations during the transition to motherhood. However, adequate measures of the body experience during pregnancy are lacking. This study aims to evaluate the psychometric properties of a new measure, the Body Experience during Pregnancy Scale (BEPS). In Study 1, the BEPS was administered to 423 pregnant women. In Study 2, 373 pregnant women completed the BEPS, as well as questionnaires assessing body shame, disrupted body boundaries, and well-being. Three BEPS subscales emerged from Study 1: body agency, body estrangement, and body visibility. In Study 2, a confirmatory factor analysis replicated the scale's structure. The factors were significantly correlated with measures of body shame, disrupted body boundaries, and well-being. The results of the present analyses suggest that the BEPS has good psychometric properties, making it useful in future research. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background A high quality decision requires that patients who meet clinical criteria for surgery are informed about the options (including non-surgical alternatives and receive treatments that match their goals. The aim of this study was to evaluate the psychometric properties and clinical sensibility of a patient self report instrument, to measure the quality of decisions about total joint replacement for knee or hip osteoarthritis. Methods The performance of the Hip/Knee Osteoarthritis Decision Quality Instrument (HK-DQI was evaluated in two samples: (1 a cross-sectional mail survey with 489 patients and 77 providers (study 1; and (2 a randomized controlled trial of a patient decision aid with 138 osteoarthritis patients considering total joint replacement (study 2. The HK-DQI results in two scores. Knowledge items are summed to create a total knowledge score, and a set of goals and concerns are used in a logistic regression model to develop a concordance score. The concordance score measures the proportion of patients whose treatment matched their goals. Hypotheses related to acceptability, feasibility, reliability and validity of the knowledge and concordance scores were examined. Results In study 1, the HK-DQI was completed by 382 patients (79% and 45 providers (58%, and in study 2 by 127 patients (92%, with low rates of missing data. The DQI-knowledge score was reproducible (ICC = 0.81 and demonstrated discriminant validity (68% decision aid vs. 54% control, and 78% providers vs. 61% patients and content validity. The concordance score demonstrated predictive validity, as patients whose treatments were concordant with their goals had more confidence and less regret with their decision compared to those who did not. Conclusions The HK-DQI is feasible and acceptable to patients. It can be used to assess whether patients with osteoarthritis are making informed decisions about surgery that are concordant with their goals.

    The primary objective of this study was to determine the structural and known-group validity as well as the inter-rater reliability of a test battery to evaluate the motor control of the craniofacial region. Seventy volunteers without TMD and 25 subjects with TMD (Axes I) per the DC/TMD were asked to execute a test battery consisting of eight tests. The tests were video-taped in the same sequence in a standardised manner. Two experienced physical therapists participated in this study as blinded assessors. We used exploratory factor analysis to identify the underlying component structure of the eight tests. Internal consistency (Cronbach's α), inter-rater reliability (intra-class correlation coefficient) and construct validity (ie, hypothesis testing-known-group validity) (receiver operating curves) were also explored for the test battery. The structural validity showed the presence of one factor underlying the construct of the test battery. The internal consistency was excellent (0.90) as well as the inter-rater reliability. All values of reliability were close to 0.9 or above indicating very high inter-rater reliability. The area under the curve (AUC) was 0.93 for rater 1 and 0.94 for rater two, respectively, indicating excellent discrimination between subjects with TMD and healthy controls. The results of the present study support the psychometric properties of test battery to measure motor control of the craniofacial region when evaluated through videotaping. This test battery could be used to differentiate between healthy subjects and subjects with musculoskeletal impairments in the cervical and oro-facial regions. In addition, this test battery could be used to assess the effectiveness of management strategies in the craniofacial region. © 2017 John Wiley & Sons Ltd.

    The investigation of learning approaches in the clinical workplace context has remained an under-researched area. Despite the validation of learning approach instruments and their applications in various clinical contexts, little is known about the extent to which an individual item, that reflects a specific learning strategy and motive, effectively contributes to characterizing students' learning approaches. This study aimed to measure nursing students' approaches to learning in a clinical practicum using the Approaches to Learning at Work Questionnaire (ALWQ). Survey research design was used in the study. A sample of year 3 nursing students (n = 208) who undertook a 6-week clinical practicum course participated in the study. Factor analyses were conducted, followed by an item response theory analysis, including model assumption evaluation (unidimensionality and local independence), item calibration and goodness-of-fit assessment. Two subscales, deep and surface, were derived. Findings suggested that: (a) items measuring the deep motive from intrinsic interest and deep strategies of relating new ideas to similar situations, and that of concept mapping served as the strongest discriminating indicators; (b) the surface strategy of memorizing facts and details without an overall picture exhibited the highest discriminating power among all surface items; and, (c) both subscales appeared to be informative in assessing a broad range of the corresponding latent trait. The 21-item ALWQ derived from this study presented an efficient, internally consistent and precise measure. Findings provided a useful psychometric evaluation of the ALWQ in the clinical practicum context, added evidence to the utility of the ALWQ for nursing education practice and research, and echoed the discussions from previous studies on the role of the contextual factors in influencing student choices of different learning strategies. They provided insights for clinical educators to measure

    The Clinical Global Impression for Schizoaffective Disorder scale is a new rating scale adapted from the Clinical Global Impression scale for use in patients with schizoaffective disorder. The psychometric characteristics of the Clinical Global Impression for Schizoaffective Disorder are described. Content validity was assessed using an investigator questionnaire. Inter-rater reliability was determined with 12 sets of videotaped interviews rated independently by two trained individuals. Test-retest reliability was assessed using 30 randomly selected raters from clinical trials who evaluated the same videos on separate occasions two weeks apart. Convergent and divergent validity and effect size were evaluated by comparing scores between the Clinical Global Impression for Schizoaffective Disorder and the Positive and Negative Syndrome Scale, 21-item Hamilton Rating Scale for Depression, and Young Mania Rating Scale scales using pooled patient data from two clinical trials. Clinical Global Impression for Schizoaffective Disorder scores were then linked to corresponding Positive and Negative Syndrome Scale scores. Content validity was strong. Inter-rater agreement was good to excellent for most scales and subscales (intra-class correlation coefficient ≥ 0.50). Test-retest showed good reproducibility, with intraclass correlation coefficients ranging from 0.444 to 0.898. Spearman correlations between Clinical Global Impression for Schizoaffective Disorder domains and corresponding symptom scales were 0.60 or greater, and effect sizes for Clinical Global Impression for Schizoaffective Disorder overall and domain scores were similar to Positive and Negative Syndrome Scale Young Mania Rating Scale, and 21-item Hamilton Rating Scale for Depression scores. Raters anticipated that the scale might be less effective in distinguishing negative from depressive symptoms, and, in fact, the results here may reflect that clinical reality. Multiple lines of evidence support the

    The Alzheimer's Disease Assessment Scale Cognitive Behavior Section (ADAS-cog), a measure of cognitive performance, has been used widely in Alzheimer's disease trials. Its key role in clinical trials should be supported by evidence that it is both clinically meaningful and scientifically sound. Its conceptual and neuropsychological underpinnings are well-considered, but its performance as an instrument of measurement has received less attention. Objective To examine the traditional psychometric properties of the ADAS-cog in a large sample of people with Alzheimer's disease. Data from three clinical trials of donepezil (Aricept) in mild-to-moderate Alzheimer's disease (n=1421; MMSE 10-26) were analysed at both the scale and component level. Five psychometric properties were examined using traditional psychometric methods. These methods of examination underpin upcoming Food and Drug Administration recommendations for patient rating scale evaluation. At the scale-level, criteria tested for data completeness, scaling assumptions (eg, component total correlations: 0.39-0.67), targeting (no floor or ceiling effects), reliability (eg, Cronbach's α: = 0.84; test-retest intraclass correlations: 0.93) and validity (correlation with MMSE: -0.63) were satisfied. At the component level, 7 of 11 ADAS-cog components had substantial ceiling effects (range 40-64%). Performance was satisfactory at the scale level, but most ADAS-cog components were too easy for many patients in this sample and did not reflect the expected depth and range of cognitive performance. The clinical implication of this finding is that the ADAS-cog's estimate of cognitive ability, and its potential ability to detect differences in cognitive performance under treatment, could be improved. However, because of the limitations of traditional psychometric methods, further evaluations would be desirable using additional rating scale analysis techniques to pinpoint specific improvements.

    There are few tools to quantify the impact of cough in cystic fibrosis (CF). The psychometric properties of the Leicester Cough Questionnaire (LCQ) and Respiratory Symptoms in CF (ReS-CF) tool were investigated in adults with CF. Validity and reliability were assessed in clinically stable participants who completed the questionnaires twice, along with the Cystic Fibrosis Questionnaire - Revised (CFQ-R). Responsiveness was assessed by change in questionnaires following treatment for an acute respiratory exacerbation. Correlations between the LCQ and CFQ-R respiratory domain were moderate (n=59, r s =0.78, p<0.001). Correlations between ReS-CF and CFQ-R respiratory domain were fair (r s =-0.50, p<0.001). The LCQ total score was repeatable (ICC 0.92, 95%CI 0.87-0.96, n=50). In those reporting improvement in symptoms following treatment (n=36), LCQ total score had a mean change of 4.6 (SD 3.7) and effect size of 1.2. The LCQ and ReS-CF appear to be valid, reliable and responsive in CF. www.anzctr.org.au: ACTRN12615000262505. Copyright © 2016 European Cystic Fibrosis Society. Published by Elsevier B.V.

    Two patient-reported outcome (PRO) questionnaires, the Hidradenitis Suppurativa Symptom Assessment (HSSA) and Hidradenitis Suppurativa Impact Assessment (HSIA), were developed to measure signs, symptoms and impacts of HS in treatment efficacy studies. In accordance with FDA guidelines and published best practices, four stages of research were conducted to create the questionnaires: concept elicitation, questionnaire construction, content evaluation and psychometric evaluation. Subjects (N = 20) who participated in the concept elicitation stage reported 15 unique HS-related signs and symptoms and 51 impacts. Following this, eight sign and symptom concepts and 21 impacts were selected for construction of the HSSA and HSIA, respectively. During content evaluation, cognitive debriefing interviews with HS subjects (N = 20) confirmed subjects could read, comprehend and meaningfully respond to both questionnaires. Modifications made after this stage of work resulted in a nine-item HSSA and a 17-item HSIA. The HSSA and HSIA were subsequently entered into a US-based observational study (N = 40), and the scores produced by each were found to be reliable, construct valid, and able to distinguish among clinically distinct groups. The HSSA and HSIA are content-valid, HS-specific, PRO questionnaires with demonstrated ability to generate reliable, valid scores when administered to patients with HS in a research setting.

    Full Text Available To report piloting and initial validation of the VQoL_CYP, a novel age-appropriate vision-related quality of life (VQoL instrument for self-reporting by children with visual impairment (VI.Participants were a random patient sample of children with VI aged 10-15 years. 69 patients, drawn from patient databases at Great Ormond Street Hospital and Moorfields Eye Hospital, United Kingdom, participated in piloting of the draft 47-item VQoL instrument, which enabled preliminary item reduction. Subsequent administration of the instrument, alongside functional vision (FV and generic health-related quality of life (HRQoL self-report measures, to 101 children with VI comprising a nationally representative sample enabled further item reduction and evaluation of psychometric properties using Rasch analysis. Construct validity was assessed through Pearson correlation coefficients.Item reduction through piloting (8 items removed for skewness and individual item response pattern and validation (1 item removed for skewness and 3 for misfit in Rasch produced a 35-item scale, with fit values within acceptable limits, no notable differential item functioning, good measurement precision, ordered response categories and acceptable targeting in Rasch. The VQoL_CYP showed good construct validity, correlating strongly with HRQoL scores, moderately with FV scores but not with acuity.Robust child-appropriate self-report VQoL measures for children with VI are necessary for understanding the broader impacts of living with a visual disability, distinguishing these from limited functioning per se. Future planned use in larger patient samples will allow further psychometric development of the VQoL_CYP as an adjunct to objective outcomes assessment.

    Estimates of unplanned pregnancy worldwide are of concern, especially in low and middle-income countries, including Brazil. Although the contraceptive prevalence rate is high in Brazil, almost half of all pregnancies are reported as unintended. The only source of nationally representative data about pregnancy intention is the Demographic and Health Survey, as with many other countries. In more recent years, however, it has been realized that concept of unintended pregnancy is potentially more complex and requires more sophisticated measurement strategies, such as the London Measure of Unplanned Pregnancy (LMUP). The LMUP has been translated and validated in other languages, but not Portuguese yet. In this study, we evaluate the psychometric properties of the LMUP in the Portuguese language, Brazilian version. A Brazilian Portuguese version of the LMUP was produced via translation and back-translation. After piloting, the mode of administration was changed from self-completion to interviewer-administration. The measure was field tested with pregnant, postpartum, and postabortion women recruited at maternity and primary health care services in Sao Paulo city. Reliability (internal consistency) was assessed using Cronbach's alpha and item-total correlations. Construct validity was assessed using principal components analysis and hypothesis testing. Scaling was assessed with Mokken analysis. 759 women aged 15-44 completed the Brazilian Portuguese LMUP. There were no missing data. The measure was acceptable and well targeted. Reliability testing demonstrated good internal consistency (alpha = 0.81, all item-rest correlations >0.2). Validity testing confirmed that the measure was unidimensional and that all hypotheses were met: there were lower LMUP median scores among women in the extreme age groups (p Portuguese LMUP is a valid and reliable measure of pregnancy planning/intention that is now available for use in Brazil.

    Full Text Available Background: Although there are different tools in a coping context, lots of them are general and not applicable in every stressful situation such as transplant. Aim: The aim of this study is to develop and psychometrically evaluate a coping tool with kidney transplant in the Iranian context and culture. Method: In this sequential exploratory study, based on theoretical and practical definitions of constructs for the concept of coping, the initial pool was extracted with 93 items. Face and content validity qualitative and quantitative were calculated. In order to assess the construct validity, exploratory factor analysis was applied. Using Cronbach's alpha and retesting, the consistency of the questionnaire was calculated Results: In the quantitative face validity, all the items whose item impact was more than 1.5 were retained. Seven items were merged during the qualitative content validity since they overlapped each other, making the number of items equal to 80 at this stage. The quantitative content validity was determined by calculating the content validity index (CVI as 0.9 and factor analysis was performed for all the 80 items. The items decreased to 69 using factor analysis and were classified under 5 categories of understanding the necessity of self-care, intelligent acceptance of changes, conscious enduring of problems, understanding supportive encouragements and spiritual enduring. Finally, the reliability of the questionnaire equaled 0.94 using Cronbach alpha. Implications for Practice: This tool, with understanding and careful testing of the coping degree of transplant patients, could help health service providers to present their services and play their preventive, caring and therapeutic roles to patients.

    Evidence-based practice and research utilisation has become a commonly used concept in health care. The Research Utilization Questionnaire (RUQ) has been recognised to be a widely used instrument measuring the perception of research utilisation among nursing staff in clinical practice. Few studies have however analysed the psychometric properties of the RUQ. The aim of this study was to examine the psychometric properties of the Swedish version of the three subscales in RUQ using a Rasch measurement model. This study has a cross-sectional design using a sample of 163 staff (response rate 81%) working in one nursing home in Sweden. Data were collected using the Swedish version of RUQ in 2012. The three subscales Attitudes towards research, Availability of and support for research use and Use of research findings in clinical practice were investigated. Data were analysed using a Rasch measurement model. The results indicate presence of multidimensionality in all subscales. Moreover, internal scale validity and person response validity also provide some less satisfactory results, especially for the subscale Use of research findings. Overall, there seems to be a problem with the negatively worded statements. The findings suggest that clarification and refining of items, including additional psychometric evaluation of the RUQ, are needed before using the instrument in clinical practice and research studies among staff in nursing homes. © 2017 Nordic College of Caring Science.

    Full Text Available Background and purpose: Using valid and reliable instruments is an important way for collecting data in qualitative researches. This paper is a report of a study conducted to examine the extent of psychometric properties of the scales in research papers published in Journal of Advanced Nursing.Methods: In this study, the Journal of Advanced Nursing was chosen for systematic review. All articles which were published during 2007-2009 in this journal were collected and articles related to instrument development were selected. Each article was completely reviewed to identify the methods of instrument validation and reliability.Results: From 980 articles published in Journal of Advanced Nursing during 2007-2009, 41 (4.18% articles were about research methodology. In these, 12 articles (29.27% were related to developing an instrument. In this study, review of 12 articles that published in Journal of Advanced Nursing, 2007-2009, showed that some of the articles did not measure psychometric properties properly, thus some of the developed scales need to measure other types of necessary validity. In addition, reliability testing needs to be performed on each instrument used in a study before other statistical analysis are performed. From 12 articles, all of the articles measured and reported Cronbach’s alpha, but four of them did not measure test-retest.Conclusions: Although researchers put a great emphasis on methodology and statistical analysis, they pay less attention to the psychometric properties of their new instruments. The authors of this article hope to draw the attention of researcher to the importance of measuring psychometric properties of new instruments.Keywords: PSYCHOMETRIC, SCALES, CRITICAL REVIEW

    Full Text Available Abstract Background Continuity of care is regarded as a core quality element in healthcare. Continuity can be related to one or more specific caregivers but also applies to collaboration within a team or across boundaries of healthcare. Measuring continuity is important to identify problems and evaluate quality improvement of interventions. This study aimed to assess the feasibility and psychometric properties of a Norwegian version of the Nijmegen Continuity Questionnaire (NCQ. Methods The NCQ was developed in The Netherlands. It measures patients’ experienced continuity of care across multiple care settings and as a multidimensional concept regardless of morbidity. The NCQ comprises 28 items categorised into three subscales; two personal continuity scales, “care giver knows me” and “shows commitment”, asked regarding the patient’s general practitioner (GP and the most important specialist; and one “team/cross boundary continuity” scale, asked regarding primary care, specialised care and cooperation between GP and specialist, with a total of seven factors. The NCQ was translated and adapted to Norwegian (NCQ-N and distributed among patients referred to somatic rehabilitation (N = 984, response rate 34.5%. Confirmatory factor analyses (CFA, Cronbach’s alpha, intra-class correlation (ICC and Bland–Altman plots were used to assess psychometric properties. Results All patients (N = 375 who had responded to all parts of the NCQ-N were included in CFA. The CFA fit indices (CFI 0.941, RMSEA 0.064 (95% CI 0.059–0.070, SRMR 0.041 support a seven-factor structure in the NCQ-N based on the three subscales of the original NCQ. Cronbach’s alpha showed internal consistency (0.84–0.97, and was highest for the team/cross-boundary subscales. The NCQ-N showed overall high reliability with ICC 0.84–91 for personal continuity factors and 0.67–0.91 for team factors, with the lowest score for team continuity within primary care

    Patient communication is a key skill for nurses involved in clinical care. Its measurement is a complex phenomenon that can be addressed through attitude evaluation. To develop and psychometrically test a measure of nurses' attitudes towards communication with patients (ACO), to study the relationship between these dimensions, and to analyse nursing attitudes. To develop and psychometrically test the ACO questionnaire. All hospitals in the province of Valencia were invited by e-mail to distribute the ACO instrument. Ten hospitals took part in the study. The study population was composed of a convenience sample of 400 hospital nurses on general or special services. The inclusion criteria were nurses at the selected centres who had previously provided an informed consent to participate. A literature review and expert consultation (N = 10) was used to develop the content of the questionnaire. The 62-item version of the instrument was applied to a convenience sample of 400 nurses between May 2015 and March 2016. Factor structure was evaluated with exploratory and confirmatory factor analysis (EFA, CFA), and reliability was evaluated with Cronbach's alpha, composite reliability (CR), and average variance extracted (AVE). The final instrument (ACO), composed of 25 items grouped into three attitude dimensions (cognitive, affective and behavioural), had good psychometric properties. In the study sample, nurses had a favourable attitude towards communication. The cognitive and affective dimensions of the ACO should be able to predict the behaviour dimension. The ACO is useful for evaluating current clinical practices, identifying educational needs and assessing the effectiveness of communication training or other interventions intended to improve communication.

    Pressure ulcers continue to be a significant problem in hospitals, nursing homes and community care settings. Pressure ulcer incidence is widely accepted as an indicator for the quality of care. Negative attitudes towards pressure ulcer prevention may result in suboptimal preventive care. A reliable and valid instrument to assess attitudes towards pressure ulcer prevention is lacking. Development and psychometric evaluation of the Attitude towards Pressure ulcer Prevention instrument (APuP). Prospective psychometric instrument validation study. A literature review was performed to design the instrument. Content validity was evaluated by nine European pressure ulcer experts and five experts in psychometric instrument validation in a double Delphi procedure. A convenience sample of 258 nurses and 291 nursing students from Belgium and The Netherlands participated in order to evaluate construct validity and stability reliability of the instrument. The data were collected between February and May 2008. A factor analysis indicated the construct of a 13 item instrument in a five factor solution: (1) attitude towards personal competency to prevent pressure ulcers (three items); (2) attitude towards the priority of pressure ulcer prevention (three items); (3) attitude towards the impact of pressure ulcers (three items); (4) attitude towards personal responsibility in pressure ulcer prevention (two items); and (5) attitude towards confidence in the effectiveness of prevention (two items). This five factor solution accounted for 61.4% of the variance in responses related to attitudes towards pressure ulcer prevention. All items demonstrated factor loadings over 0.60. The instrument produced similar results during stability testing [ICC=0.88 (95% CI=0.84-0.91, Ppressure ulcer prevention in patient care, education, and research.

    The Short Opiate Withdrawal Scale (SOWS)-Gossop is a 10-item questionnaire developed to evaluate opioid withdrawal symptom severity. The scale was derived from the original 32-item Opiate Withdrawal Scale in order to reduce redundancy while providing an equally sensitive measure of opioid withdrawal symptom severity appropriate for research and clinical practice. The objective of this study was to examine the psychometric properties and provide score interpretation guidelines for the SOWS-Gossop 10-item version. Blinded, pooled data from two trials assessing the efficacy of lofexidine hydrochloride in reducing withdrawal symptoms in patients undergoing opioid detoxification were used to evaluate the quantitative psychometric properties and score interpretation of the SOWS-Gossop. Five hundred fifty-five (N=555) observations were available at baseline with numbers decreasing to n=213 at day 7. Mean (standard deviation) SOWS-Gossop scores were 10.4 (6.86) at baseline, 8.7 (6.49) on day 1, 10.5 (7.21) on day 2, and 3.1 (3.95) on day 7. Confirmatory factor analysis indicated that the SOWS-Gossop items loaded on a single factor consistent with a single total score. Intra-class correlations (95% confidence interval) were 0.78 (0.70-0.85) between baseline and day 1, 0.84 (0.79-0.89) between days 4 and 5, and 0.88 (0.83-0.91) between days 6 and 7, demonstrating good test-retest reliability. Mean SOWS-Gossop scores varied significantly (popioid withdrawal and has excellent psychometric properties. The SOWS-Gossop is an appropriate, precise, and sensitive measure to evaluate the symptoms of acute opioid withdrawal in research or clinical settings. Copyright © 2016 Elsevier Ltd.

    Impaired mobility is a prevalent condition among care-dependent persons living in nursing homes. Therefore, competence development of nursing staff in mobility care is important. This study aimed to develop and initially test the Kinaesthetics Competence Self-Evaluation (KCSE) scale for assessing nursing staff's competence in mobility care. The KCSE scale was developed based on an analysis of the concept of nurses' competence in kinaesthetics. Kinaesthetics is a training concept that provides theory and practice about movement foundations that comprise activities of daily living. The scale contains 28 items and four subscales (attitude, dynamic state, knowledge and skills). Content validity was assessed by determining the content validity index within two expert panels. Internal consistency and construct validity were tested within a cross-sectional study in three nursing homes in the German-speaking region of Switzerland between September and November 2015. The content validity index for the entire scale was good (0.93). Based on a sample of nursing staff ( n  = 180) the internal consistency results were good for the whole scale (Cronbach's alpha = 0.91) and for the subscales knowledge and skills (α = 0.91, 0.86), acceptable for the subscale attitude (α = 0.63) and weak for the subscale dynamic state (α = 0.54). Most items showed acceptable inter-item and item-total correlations. Based on the exploratory factor analysis, four factors explaining 52% of the variance were extracted. The newly developed KCSE scale is a promising instrument for measuring nursing staff's attitude, dynamic state, knowledge, and skills in mobility care based on kinaesthetics. Despite the need for further psychometric evaluation, the KCSE scale can be used in clinical practice to evaluate competence in mobility care based on kinaesthetics and to identify educational needs for nursing staff.

    With the integration of the evaluation of patient satisfaction in the overall assessment of healthcare services, authorities can be assured about the alignment of these services with patient needs and the suitability of care provided at the local level. This study was conducted in 2013 in Zahedan, Iran, in order to assess the psychometric properties of the Iranian version of the mackey childbirth satisfaction rating scale (MCSRS). For this study, a methodological design was used. After translating the MCSRS and confirming its initial validity, the questionnaires were distributed among women with uncomplicated pregnancies and no prior history of cesarean section. The participants had given birth to healthy, full-term, singletons (with cephalic presentation) via normal vaginal delivery at hospitals within the past six months. Cronbach's alpha and test-retest (via the intraclass correlation coefficient) were applied to analyze the internal consistency and reliability of the scale. Moreover, the validity of the scale was tested via exploratory factor analysis, confirmatory factor analysis, and convergent validity. The MCSRS consists of six subscales. Through the process of validation, two partner-related items ("partner" subscale) of the scale were excluded due to cultural barriers and hospital policies. Cronbach's alpha for the total scale was 0.78. It ranged between 0.70 and 0.86 for five subscales, and was 0.31 for the "baby" subscale. Factor analysis confirmed the subscales of "nurse," "physician," and "baby," which were identified in the original scale. However, in the translated version, the "self" subscale was divided into two separate dimensions. The six subscales explained 70.37% of the variance. Confirmatory factor analysis indicated a good fitness for the new model. Convergent validity showed a significant correlation between the MCSRS and the SERVQUAL scale (r = 0.72, P < 0.001). Moreover, the Farsi version of the MCSRS showed excellent repeatability (r = 0

    Psychometrics provide the mathematical underpinnings for psychological assessment. From the late 19th century, a plethora of methodological research achievements equipped researchers and clinicians with efficient tools whose practical value becomes more evident in the era of the internet and big data. Nowadays, powerful probabilistic models exist for most types of data and research questions. As the usability of the psychometric scales is better comprehended, there is an increased interest in applied research outcomes. Paradoxically, while the interest in applications for psychometric scales increases, publishing research on the development and/or evaluation of those scales per se, is not welcomed by many relevant journals. This special issue in psychometrics is therefore a great opportunity to briefly review the main ideas and methods used in psychometrics, and to discuss the challenges in contemporary applied psychometrics.

    To examine the psychometrics of the Affiliate Stigma Scale using rigorous psychometric analysis: classical test theory (CTT) (traditional) and Rasch analysis (modern). Differential item functioning (DIF) items were also tested using Rasch analysis. Caregivers of relatives with mental illness (n = 453; mean age: 53.29 ± 13.50 years) were recruited from southern Taiwan. Each participant filled out four questionnaires: Affiliate Stigma Scale, Rosenberg Self-Esteem Scale, Beck Anxiety Inventory, and one background information sheet. CTT analyses showed that the Affiliate Stigma Scale had satisfactory internal consistency (α = 0.85-0.94) and concurrent validity (Rosenberg Self-Esteem Scale: r = -0.52 to -0.46; Beck Anxiety Inventory: r = 0.27-0.34). Rasch analyses supported the unidimensionality of three domains in the Affiliate Stigma Scale and indicated four DIF items (affect domain: 1; cognitive domain: 3) across gender. Our findings, based on rigorous statistical analysis, verified the psychometrics of the Affiliate Stigma Scale and reported its DIF items. We conclude that the three domains of the Affiliate Stigma Scale can be separately used and are suitable for measuring the affiliate stigma of caregivers of relatives with mental illness.

    The purpose of the study was to develop and psychometrically test the Nurses Clinical Reasoning Scale. Clinical reasoning is an essential skill for providing safe and quality patient care. Identifying pre-graduates' and nurses' needs and designing training courses to improve their clinical reasoning competence becomes a critical task. However, there is no instrument focusing on clinical reasoning in the nursing profession. Cross-sectional design was used. This study included the development of the scale, a pilot study that preliminary tested the readability and reliability of the developed scale and a main study that implemented and tested the psychometric properties of the developed scale. The Nurses Clinical Reasoning Scale was developed based on the Clinical Reasoning Model. The scale includes 15 items using a Likert five-point scale. Data were collected from 2013-2014. Two hundred and fifty-one participants comprising clinical nurses and nursing pre-graduates completed and returned the questionnaires in the main study. The instrument was tested for internal consistency and test-retest reliability. Its validity was tested with content, construct and known-groups validity. One factor emerged from the factor analysis. The known-groups validity was confirmed. The Cronbach's alpha for the entire instrument was 0·9. The reliability and validity of the Nurses Clinical Reasoning Scale were supported. The scale is a useful tool and can be easily administered for the self-assessment of clinical reasoning competence of clinical nurses and future baccalaureate nursing graduates. Study limitations and further recommendations are discussed. © 2015 John Wiley & Sons Ltd.

    The Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 instrument (MDF-Fibro-17) has been developed for use in fibromyalgia (FM) clinical studies and includes 5 domains: Global Fatigue Experience, Cognitive Fatigue, Physical Fatigue, Motivation, and Impact on Function. Psychometric properties of the MDF-Fibro-17 needed to demonstrate the appropriateness of using this instrument in clinical studies are presented. Psychometric analyses were conducted to evaluate the factor structure, reliability, validity, and responsiveness of the MDF-Fibro-17 using data from a Phase 2 clinical study of FM patients (N = 381). Confirmatory factor analyses (CFA) were performed to ensure understanding of the multidimensional domain structure, and a secondary factor analysis of the domains examined the appropriateness of calculating a total score in addition to domain scores. Longitudinal psychometric analyses (test-retest reliability and responder analysis) were also conducted on the data from Baseline to Week 6. The CFA supported the 17-item, 5 domain structure of this instrument as the best fit of the data: comparative fit index (CFI) and non-normed fit index (NNFI) were 0.997 and 0.992 respectively, standardized root mean square residual (SRMR) was 0.010 and the root mean square error of approximation (RMSEA) was 0.06. In addition, total score (CFI and NNFI both 0.95) met required standards. For the total and 5 domain scores, reliability and validity data were acceptable: test-retest and internal consistency were above 0.9; correlations were as expected with the Global Fatigue Index (GFI) (0.62-0.75), Fibromyalgia Impact Questionnaire (FIQ) Total (0.59-0.71), and 36-Item Short Form Health Survey (SF-36) vitality (VT) (0.43-0.53); and discrimination was shown using quintile scores for the GFI, FIQ Total, and Pain Numeric Rating Scale (NRS) quartiles. In addition, sensitivity to change was demonstrated with an overall mean responder score of -2.59 using anchor-based methods

    Introduction Postpartum depression (PPD) is a prevalent condition with a serious impact. The early identification of women at risk for developing PPD allows for primary prevention and the delivery of timely appropriate referrals. This study investigated the validity and reliability of the postnatal version of the Postpartum Depression Predictors Inventory-Revised (PDPI-R), an instrument widely studied internationally, in Portuguese women. Methods The sample consisted of 204 women who participated in an online cross-sectional survey. Participants completed the European Portuguese versions of the PDPI-R, the Edinburgh Postnatal Depression Scale (EPDS), and the Postnatal Negative Thoughts Questionnaire at 1-2 months postpartum. Additionally, ROC analyses were performed to conduct an exploratory analysis of the instruments' predictive validity. Results The prevalence rates of clinical postpartum depressive symptoms were 27.5 and 14.2% using the cut-off scores of 9 and 12, respectively, on the EPDS. The European Portuguese postnatal version of the PDPI-R demonstrated acceptable reliability and satisfactory construct and convergent validity. When using the EPDS > 9 cut-off score, the exploratory analyses yielded a sensitivity of 76.8% and a specificity of 73.0% with a cut-off score of 5.5 [area under the curve = 0.816]. Discussion These preliminary findings encourage the use of the postnatal version of the PDPI-R as a screening tool to identify Portuguese women at high risk for developing PPD. Subsequent assessments are needed to support the routine application of the PDPI-R both in research and for clinical purposes.

    The purpose of this study was to develop a Portuguese version of the Epilepsy Surgery Inventory (ESI-55) and to assess its psychometric properties. Sixty patients with temporal lobe epilepsy related to unilateral mesial temporal sclerosis who underwent presurgical evaluation at the Universidade Federal de São Paulo (UNIFESP) formed the sample for this study. The psychometric properties of the ESI-55 included: reliability, validity, and responsiveness. Internal consistency was high in all domains (Cronbach's alpha ranging from 0.76 for Social Function to 0.88 for Physical Function) except Overall Quality of Life (alpha=0.45). Test-retest reliability after 1 week was good, with the intraclass correlation coefficient ranging from 0.79 (Energy/Fatigue) to 0.92 (Role Limitations due to Emotional Problems). Interrater reliability ranged from 0.84 (Cognitive Function) to 0.94 (Role Limitations due to Physical Problems). For construct validity, we verified a high correlation between the ESI-55 and Health Assessment Questionnaire-8 for the Physical Function domain (Pearson linear correlation=-0.84), and a moderate correlation for the Pain domain (P=-0.58), but for the other subscales no correlation was detected. Beck Depression Inventory and ESI-55 domains were highly statistically correlated (ANOVA: P0.05). With respect to demographic characteristics, a statistically significant correlation was observed for the variable educational level (Student t, PESI-55 scores. There was a high correlation between seizure frequency and ESI-55 domains for clinical variables (ANOVA, Pgroup in three domains--Health Perception (1.24), Emotional Well-Being (1.32), and Energy/Fatigue (1.48)-as reflected by the standard response mean and the effect size of the sample. Our results support the psychometric properties of the Portuguese version of the ESI-55 as a measure of health-related quality of life.

    Full Text Available Abstract Background The Problem Areas in Diabetes (PAID survey is a measure of diabetes-related stress for which reported use has been in largely Caucasian populations. Our purpose was to assess the psychometric properties of the PAID in Southern rural African American women with Type 2 diabetes. Methods A convenience sample of African American women (N = 131 ranging from 21–50 years of age and diagnosed with Type 2 diabetes were recruited for a survey study from two rural Southern community health centers. Participants completed the PAID, Center for Epidemiological Studies-Depression Scale (CES-D, and the Summary of Diabetes Self-Care Activities Scale (SDSCA. Factor analysis, Cronbach's coefficient alpha, and construct validation facilitated psychometric evaluation. Results A principle component factor analysis of the PAID yielded two factors, 1 a lack of confidence subscale, and 2 a negative emotional consequences subscale. The Lack of Confidence and Negative Emotional Consequences subscales, but not the overall PAID scale, were associated with glycemic control and body mass index, respectively. Relationships with measures of depression and diabetes self-care supported construct validity of both subscales. Both subscales had acceptable (alpha = 0.85 and 0.94 internal consistency measures. Conclusion A psychometrically sound two-factor solution to the PAID survey is identified in Southern, rural African American women with Type 2 diabetes. Lack of confidence in and negative emotional consequences of diabetes self-care implementation provide a better understanding of determinants of glycemic control and weight than an aggregate of the two scales.

    To evaluate the psychometric properties of the Spanish Brief Religious Coping Scale (S-BRCS). A descriptive correlational design was used to conduct the study among a convenience sample of 121 Mexican Americans with diabetes. The positive and negative religious coping subscales had Cronbach’s alphas of .85 and .86, respectively. All interitem and item-to-total correlations for each subscale were above the recommended criteria of .30. Factor loadings of the positive subscale using oblique (oblimin) and orthogonal (varimax) rotation ranged from .71 to .86 and from .72 to .86, respectively.Factor loadings of the negative subscale using oblimin and varimax rotation ranged from .64 to .83 and from .63 to .83,respectively. The S-BRCS was found to be a valid and reliable instrument to measure religious coping among Spanish-speaking Mexican Americans with type 2 diabetes. IMPLICATIONS FOR FURTHER RESEARCH AND PRACTICE: Further psychometric evaluation of the S-BRCS among larger sample of Mexican Americans and other Hispanic ethnic groups is warranted. The S-BRCS has the potential to become a standard instrument that can be used by clinicians who work with Hispanic clients with diabetes mellitus to provide culturally competent diabetes care.

    Full Text Available The Positive–Negative Sex-Role Inventory (PN-SRI assesses gender identity. The aim of this study was to evaluate the validity and reliability of a Swedish version of the PN-SRI in a population of 70-year-olds within the Gothenburg H70-study in Sweden. The overarching objective of testing the PN-SRI within the H70-study was to evaluate its usability to further study gender identity in large population-based samples of older adults. A total of 1124 individuals participated in the psychometric testing. A sub-sample of these (n = 406 provided a comprehensive survey regarding societal norms on femininity and masculinity. Reliability and validity tests were performed using Cronbach’s Alpha and factor analyses. The Cronbach’s α coefficients (0.734–0.787 indicated a satisfactory level of internal consistency, and the four-factor model (Model 2 fitted the data at an acceptable level (root-mean-square error of approximation, RMSEA = 0.068, standardized root-mean-square residual, SRMR = 0.07. This cross-cultural adaptation of the PN-SRI indicates that it may be applicable in a Swedish research setting comprising older adults. Future research is needed to further test the psychometric properties of this scale. Adding the PN-SRI to population-based studies will contribute to providing a nuanced way of analyzing differences and similarities among men and women.

Methods: From October 21, 2015 to December 31, 2016, we administered the Italian PDI to all patients hospitalized in an acute psychiatric ward, who provided their consent and completed it at discharge (n=165. We performed Cronbach’s alpha coefficient and principal factor analysis. We administered other scales concomitantly to analyze the concurrent validity of PDI. We applied stepwise multiple linear regression to identify the patients’ demographic and clinical variables related to the PDI score. Results: Our response rate was 93%, with excellent internal consistency (Cronbach’s alpha coefficient=0.94. The factorial analysis showed three factors with eigenvalue >1, which explained >80% of total variance: 1 “loss of self-identity and anxiety for the future”, 2

    To develop an evaluation system of clinical competencies for the practicum of nursing students based on the Nursing Interventions Classification (NIC). Psychometric validation study: the first two phases addressed definition and content validation, and the third phase consisted of a cross-sectional study for analyzing reliability. The study population was undergraduate nursing students and clinical tutors. Through the Delphi technique, 26 competencies and 91 interventions were isolated. Cronbach's α was 0.96. Factor analysis yielded 18 factors that explained 68.82% of the variance. Overall inter-item correlation was 0.26, and total-item correlation ranged between 0.66 and 0.19. A competency system for the nursing practicum, structured on the NIC, is a reliable method for assessing and evaluating clinical competencies. Further evaluations in other contexts are needed. The availability of standardized language systems in the nursing discipline supposes an ideal framework to develop the nursing curricula. © 2015 Sigma Theta Tau International.

    It is obvious that unhealthy nutritional behaviors have caused the increasing incidence of diabetes. This study aimed to design the Measure of Nutritional Perceptions and Behaviors in diabetic men and to evaluate its psychometric properties. A questionnaire was developed within 7 factors. Three methods of face validity, content validity, and construct validity were employed to ensure the validity of the scale. 206 men with diabetes completed the questionnaires. Internal was used to evaluate the reliability of the scale. The mean age of men was 58.26 (9.74) years. Results showed that each item in the final questionnaire was highly correlated with the total score of each dimension Pnutritional behaviors were desired and the overall structure of the questions was confirmed. This questionnaire can be used to identify individuals at risk for unhealthy nutritional behaviors and also to conduct and evaluate the impact of educational interventions. Copyright © 2017.

    This study investigated the use of a pulsed Holmium:YAG ((lambda) equals 2.09 micrometers ) laser- fiber microsurgical system for laser stapedotomy. This system ablates human stapes bones effectively with minimal thermal damage. The study was designed to determine the effectiveness of the Ho:YAG laser (Schwartz Electro Optics, Inc., Orlando, FL) for stapedotomy and to evaluate temperature changes within the cochlea during the ablation process. Human cadaveric temporal bones were obtained and the stapes portion of the ossicular chain was removed. A 200 micrometers diameter low OH quartz fiber was used to irradiate these stapes bones in an air environment. The laser was pulsed at 2 Hz, 250 microsecond(s) ec pulse width and an irradiance range of 100 - 240 J/cm2 was used to ablate holes in the stapes footplate. The resultant stapedotomies created had smooth 300 micrometers diameter holes with a minimum of circumferential charring. Animal studies in-vivo were carried out in chinchillas to determine the caloric spread within the cochlea. A 0.075 mm Type T thermocouple was placed in the round window. Average temperature change during irradiation of the stapes footplate recorded in the round window was 3.6 degree(s)C. The data suggest that stapedotomy using the Ho:YAG laser can result in a controlled ablation of the stapes footplate with minimal thermal damage to the surrounding stapes. Optical coupling using fiberoptic silica fibers is an ideal method for delivering laser energy to the stapes during stapedotomy.

    Charcot-Marie-Tooth Neuropathy Score second version (CMTNSv2) is a validated clinical outcome measure developed for use in clinical trials to monitor disease impairment and progression in affected CMT patients. Currently, all items of CMTNSv2 have identical contribution to the total score. We used Rasch analysis to further explore psychometric properties of CMTNSv2, and in particular, category response functioning, and their weight on the overall disease progression. Weighted category responses represent a more accurate estimate of actual values measuring disease severity and therefore could potentially be used in improving the current version. © 2014 Peripheral Nerve Society.

    Full Text Available Abstract Background Social phobia (social anxiety disorder - SAD is a rather common but often undetected and undertreated psychiatric condition in youths. Screening of SAD in young individuals in community samples is thus important in preventing negative outcomes. The present study is the first report on the psychometric properties of the Social Phobia Screening Questionnaire for Children and adolescents (SPSQ-C. Methods The SPSQ-C was administered to a community sample of high-school students. Test-retest reliability over three weeks was evaluated (n = 127 and internal consistency was calculated for items measuring level of fear in eight social situations. To measure concurrent validity, subjects who reported SAD on at least one occasion and randomly selected non-cases were blindly interviewed with the Structured Clinical Interview for DSM-IV Axis-I disorders (SCID-I, as gold standard (n = 51. Results A moderate test-retest reliability, r = .60 (P Conclusion The SPSQ-C is a short and psychometrically sound questionnaire for screening of SAD in adolescents, with the advantage of being based on the DSM-IV criteria.

    The Sleep Condition Indicator (SCI) and Insomnia Severity Index (ISI) are commonly used instruments to assess insomnia. We evaluated their psychometric properties, particularly their discriminant validity against structured clinical interview (according to DSM-5 and ICSD-3), and their concurrent validity with measures of sleep and daytime functioning. A total of 158 young adults, 16% of whom were diagnosed with DSM-5 insomnia disorder and 13% with ICSD-3 Chronic Insomnia by structured interview, completed the ISI and SCI twice in 7-14 days, in addition to measures of sleep and daytime function. The Chinese version of the SCI was validated with good psychometric properties (ICC = 0.882). A cutoff of ≥8 on the ISI, ≤5 on the SCI short form, and ≤21 on the SCI achieved high discriminant validity (AUC > 0.85) in identifying individuals with insomnia based on both DSM-5 and ICSD-3 criteria. The SCI and ISI had comparable associations with subjective (0.18 sleep (0.31 disorder. Moreover, they showed good concordance with measures of daytime dysfunction, as well as subjective and objective sleep. The SCI and ISI are recommended for use in clinical and research settings.

    To describe the psychometric evaluation and item response theory calibration of the PROMIS Pediatric Life Satisfaction item banks, child-report, and parent-proxy editions. A pool of 55 life satisfaction items was administered to 1992 children 8-17 years old and 964 parents of children 5-17 years old. Analyses included descriptive statistics, reliability, factor analysis, differential item functioning, and assessment of construct validity. Thirteen items were deleted because of poor psychometric performance. An 8-item short form was administered to a national sample of 996 children 8-17 years old, and 1294 parents of children 5-17 years old. The combined sample (2988 children and 2258 parents) was used in item response theory (IRT) calibration analyses. The final item banks were unidimensional, the items were locally independent, and the items were free from impactful differential item functioning. The 8-item and 4-item short form scales showed excellent reliability, convergent validity, and discriminant validity. Life satisfaction decreased with declining socio-economic status, presence of a special health care need, and increasing age for girls, but not boys. After IRT calibration, we found that 4- and 8-item short forms had a high degree of precision (reliability) across a wide range (>4 SD units) of the latent variable. The PROMIS Pediatric Life Satisfaction item banks and their short forms provide efficient, precise, and valid assessments of life satisfaction in children and youth.

The three-item Brief Adolescent Gambling Screen (BAGS was derived from the nine-item Gambling Problem Severity Subscale (GPSS of the Canadian Adolescent Gambling Inventory (CAGI using a secondary analysis of existing CAGI data. The sample of 105 adolescents included 49 females and 56 males from Canada who completed the CAGI, a self-administered measure of DSM-IV diagnostic criteria for Pathological Gambling, and a clinician-administered diagnostic interview including the DSM-IV diagnostic criteria for Pathological Gambling (both of which were adapted to yield DSM-5 Gambling Disorder diagnosis. A stepwise multivariate discriminant function analysis selected three GPSS items as the best predictors of a diagnosis of Gambling Disorder. The BAGS demonstrated satisfactory estimates of reliability, validity and classification accuracy and was equivalent to the nine-item GPSS of the CAGI and the BAGS was more accurate than the SOGS-RA. The BAGS estimates of classification accuracy include hit rate = 0.95, sensitivity = 0.88, specificity = 0.98, false positive rate = 0.02, and false negative rate = 0.12. Since these classification estimates are preliminary, derived from a relatively small sample size, and based upon the same sample from which the items were selected, it will be important to cross-validate the BAGS with larger and more diverse samples. The BAGS should be evaluated for use as a screening tool in both clinical and school settings as well as epidemiological surveys.

    This study aimed to investigate the factor structure and psychometric properties of a Polish version of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015). Data were collected from 721 individuals residing in various regions of Poland. There were two subsamples (n=336, age M=34.95, SD=10.83; and n=385, age M=35.38, SD=10.83). Both principal-axis and confirmatory factor analyses supported the one-dimensional structure of BAS-2 scores. Moreover, full scalar invariance of the BAS-2 in Poland across sex was demonstrated. Scores on the Polish BAS-2 had adequate internal consistency. Convergent validity was demonstrated through significant correlations between BAS-2 scores and variables related to body image (body and appearance self-conscious emotions), well-being (self-esteem, positive affect, and positive orientation), and body mass index. These results indicate that the Polish BAS-2 is an appropriate and psychometrically-sound measure of body appreciation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This article describes the systematic construction and psychometric analysis of a knowledge assessment instrument for phase II cardiac rehabilitation (CR) patients measuring risk modification disease management knowledge and behavioral outcomes derived from national standards relevant to secondary prevention and management of cardiovascular disease. First, using adult curriculum based on disease-specific learning outcomes and competencies, a systematic test item development process was completed by clinical staff. Second, a panel of educational and clinical experts used an iterative process to identify test content domain and arrive at consensus in selecting items meeting criteria. Third, the resulting 31-question instrument, the Cardiac Knowledge Assessment Tool (CKAT), was piloted in CR patients to ensure use of application. Validity and reliability analyses were performed on 3638 adults before test administrations with additional focused analyses on 1999 individuals completing both pretreatment and posttreatment administrations within 6 months. Evidence of CKAT content validity was substantiated, with 85% agreement among content experts. Evidence of construct validity was demonstrated via factor analysis identifying key underlying factors. Estimates of internal consistency, for example, Cronbach's α = .852 and Spearman-Brown split-half reliability = 0.817 on pretesting, support test reliability. Item analysis, using point biserial correlation, measured relationships between performance on single items and total score (P knowledge instrument specifically designed for an adult CR population was systematically developed and tested in a large representative patient population, satisfying psychometric parameters, including validity and reliability.

    Moral distress is a kind of suffering that nurses may experience when they act in ways that are considered inconsistent with moral values, leading to a perceived compromise of moral integrity. Consequences are mostly negative and include physical and psychological symptoms, in addition to organizational implications. To psychometrically test the Moral Distress Risk Scale. A methodological study was realized. Data were submitted to exploratory factorial analysis through the SPSS statistical program. Participants and research context: In total, 268 nurses from hospitals and primary healthcare settings participated in this research during the period of March to June of 2016. Ethical considerations: This research has ethics committee approval. The Moral Distress Risk Scale is composed of 7 factors and 30 items; it shows evidence of acceptable reliability and validity with a Cronbach's α = 0.913, a total variance explained of 59%, a Kaiser-Meyer-Olkin = 0.896, and a significant Bartlett <0.001. Concerns about moral distress should be beyond acute care settings, and a tool to help clarify critical points in other healthcare contexts may add value to moral distress speech. Psychometric results reveal that the Moral Distress Risk Scale can be applied in different healthcare contexts.

    The aim of this study was to develop an instrument (University of Auckland General Practice Report of Educational Environment: UAGREE) with robust psychometric properties that measured the educational environment of undergraduate primary care. The questions were designed to incorporate measurements of the teaching of cultural competence. Following a structured consensus process and an initial pilot, a list of 55 questions was developed. All Year 5 and 6 students completing a primary care attachment at Auckland University were invited to complete the questionnaire. The results were analysed using exploratory factor analysis and confirmatory factor analysis resulting in a 16-item instrument. Three factors were identified explaining 53% of the variance. The items' reliability within the factors were high (Learning: 0.894; Teaching: 0.871; Cultural competence: 0.857). Multiple groups analysis by gender; and separately across ethnic groups did not find significant differences between groups. UAGREE is a specific instrument measuring the undergraduate primary care educational environment. Its questions fit within established theoretical educational environment frameworks and the incorporation of cultural competence questions reflects the importance of teaching cultural competence within medicine. The psychometric properties of UAGREE suggest that it is a reliable and valid measure of the primary care education environment.

    Full Text Available Learned helplessness (LH is defined as a passive behavior characterized by an inability to learn that may affect the academic success of students. Conversely, students who show good motivation skills, optimism and perseverance are more focused on tasks and ‘mastery oriented’ (derived from Mastery Orientation, MO. The purpose of this study was to develop a self-report measurement of LH and MO - the Learned Helplessness Questionnaire (LHQ - for the Italian scholastic context. We translated and adapted a student self-evaluation register, the Student behaviour checklist, and administered the questionnaire to Italian students in order to provide a preliminary factor structure. Exploratory factor analyses conducted support a two-factor model and acceptable internal reliability of the Italian LHQ.The results encourage the conduction of further analysis to assess the psychometric characteristics of the LHQ in depth.

    Despite the expanding use of undergraduate student peer counseling interventions aimed at reducing college student drinking, few programs evaluate peer counselors' competency to conduct these interventions. The present research describes the development and psychometric assessments of the Peer Proficiency Assessment (PEPA), a new tool for examining Motivational Interviewing adherence in undergraduate student peer delivered interventions. Twenty peer delivered sessions were evaluated by master and undergraduate student coders using a cross-validation design to examine peer based alcohol intervention sessions. Assessments revealed high inter-rater reliability between student and master coders and good correlations between previously established fidelity tools. Findings lend support for the use of the PEPA to examine peer counselor competency. The PEPA, training for use, inter-rater reliability information, construct and predictive validity, and tool usefulness are described.

    This study examined the psychometric properties of a Spanish translation of the Body and Appearance Self-Conscious Emotions Scale (BASES; Castonguay et al., 2014) in a sample of university Spanish students. A total of 815 participants enrolled in two public universities located in Almería and Elche, Spain, completed the BASES along with measures of social physique anxiety and positive/negative affect. Exploratory and confirmatory factor analyses showed that one item failed to load clearly on the hypothesized factor (guilt). Once it was removed, results supported the hypothesized four-factor structure. Evidence of invariance of the four-factor structure across sex was obtained. Scores on the BASES showed adequate internal consistency and acceptable convergent validity. Compared to men, women reported significantly higher body and appearance-related guilt and shame, and significant lower authentic and hubristic pride. Preliminary evidence supporting the validity and reliability of the Spanish translation of the BASES is provided. Copyright © 2018 Elsevier Ltd. All rights reserved.

    This study evaluated the psychometric properties of the Filipino versions of the Duke University Religion Index (DUREL-F) and the Spiritual Coping Strategies scale (SCS-F) for hemodialysis (HD) patients in the Philippines. A convenient sample of 162 HD patients was included in this descriptive, cross-sectional study. The DUREL-F and SCS-F exhibited acceptable internal consistency and stability reliability, as well as excellent content and construct validity. The findings confirmed the soundness of the psychometric properties of the two scales. Thus, they can be used for timely and accurate assessment of religiosity and spiritual coping utilization among Filipino patients receiving HD.

    Full Text Available In 698 respondents selected from the community, the authors examined the psychometric properties of the Dutch version of the Responses to Positive Affect questionnaire (RPA; Feldman, Joormann, & Johnson, 2008 which measures ruminative and dampening thoughts in response to positive affect. In a first sample ('n' = 170, exploratory factor analyses largely replicated the 3-factor model obtained by Feldman et al. (2008 with the following factors: Dampening, Self-focused positive rumination, and Emotion-focused positive rumination. The 3-factor model revealed in the first sample was confirmed using confirmatory factor analyses in a second independent sample of 528 respondents. All subscales showed adequate internal consistency and evidence of convergent and incremental validity with concurrent measures of depressive rumination, depressive symptoms, trait hypomania, and positive and negative affect. Results underscore the value of assessing responses to positive as well as negative affect in the study of mood disorders.

    Background and aims Research examining problematic mobile phone use has increased markedly over the past 5 years and has been related to "no mobile phone phobia" (so-called nomophobia). The 20-item Nomophobia Questionnaire (NMP-Q) is the only instrument that assesses nomophobia with an underlying theoretical structure and robust psychometric testing. This study aimed to confirm the construct validity of the Persian NMP-Q using Rasch and confirmatory factor analysis (CFA) models. Methods After ensuring the linguistic validity, Rasch models were used to examine the unidimensionality of each Persian NMP-Q factor among 3,216 Iranian adolescents and CFAs were used to confirm its four-factor structure. Differential item functioning (DIF) and multigroup CFA were used to examine whether males and females interpreted the NMP-Q similarly, including item content and NMP-Q structure. Results Each factor was unidimensional according to the Rach findings, and the four-factor structure was supported by CFA. Two items did not quite fit the Rasch models (Item 14: "I would be nervous because I could not know if someone had tried to get a hold of me;" Item 9: "If I could not check my smartphone for a while, I would feel a desire to check it"). No DIF items were found across gender and measurement invariance was supported in multigroup CFA across gender. Conclusions Due to the satisfactory psychometric properties, it is concluded that the Persian NMP-Q can be used to assess nomophobia among adolescents. Moreover, NMP-Q users may compare its scores between genders in the knowledge that there are no score differences contributed by different understandings of NMP-Q items.

    Full Text Available Abstract Background Negative affect and difficulties in its regulation have been connected to several adverse psychological consequences. While several questionnaires exist, it would be important to have a theory-based measure that includes clinically relevant items and shows good psychometric properties in healthy and patient samples. This study aims at developing such a questionnaire, combining the two Gross [1] scales Reappraisal and Suppression with an additional response-focused scale called Externalizing Behavioral Strategies covering clinically relevant items. Methods The samples consisted of 684 students (mean age = 23.3, SD = 3.5; 53.6% female and 369 persons with mixed mental disorders (mean age = 36.0 SD = 14.6; 71.2% female. Items for the questionnaire were derived from existing questionnaires and additional items were formulated based on suggestions by clinical experts. All items start with “When I don’t feel well, in order to feel better…”. Participants rated how frequently they used each strategy on a 5-point Likert scale. Confirmatory Factor Analyses were conducted to verify the factor structure in two separate student samples and a clinical sample. Group comparisons and correlations with other questionnaires were calculated to ensure validity. Results After modification, the CFA showed good model fit in all three samples. Reliability scores (Cronbach’s α for the three NARQ scales ranged between .71 and .80. Comparisons between students and persons with mental disorders showed the postulated relationships, as did comparisons between male and female students and persons with or without Borderline Personality Disorder. Correlations with other questionnaires suggest the NARQ’s construct validity. Conclusions The results indicate that the NARQ is a psychometrically sound and reliable measure with practical use for therapy planning and tracking of treatment outcome across time. We advocate the integration

    Full Text Available Abstract Background Caring for a child with a chronic condition, such as sickle cell disease, can have a significant impact on parents and families. In order to provide comprehensive care and support to these families, psychometrically sound instruments are needed as an initial step in measuring the impact of chronic diseases on parents and families. We sought to evaluate the psychometric properties of the PedsQL™ Family Impact Module in populations of children with and without sickle cell disease. In addition, we sought to determine the correlation between parent's well being and their proxy report of their child's health-related quality of life (HRQL. Methods We conducted a cross-sectional study of parents of children with and without sickle cell disease who presented to an urban hospital-based sickle cell disease clinic and an urban primary care clinic. We assessed the HRQL and family functioning of both groups of parents utilizing the PedsQL™ Family Impact Module. The reliability, validity and factor structure of the instrument were determined and scores from the instrument were correlated with scores from parent-proxy report of their child's HRQL using the PedsQL™ 4.0 Generic Core Scales. Results Parents of 170 children completed the module (97 parents of children with sickle cell disease and 73 parents of children without sickle cell disease. The Family Impact Module had high ceiling effects but was reliable (Cronbach's alpha > 0.80 in all scales. The empirical factor structure was generally consistent with the theoretical factor structure and supported construct validity. The Family Impact Module discriminated between parents of children with severe sickle cell disease from parents of children with mild disease or no disease in the areas of communication and worry. There were no significant differences across any of the subscales between parents of children with mild sickle cell disease and those with no disease. Parents with higher

    Full Text Available This paper offers a critical assessment of the psychometric properties of a standard higher education end-of-course evaluation. Using both exploratory factor analysis (EFA and Rasch modeling, the authors investigate the (a an overall assessment of dimensionality using EFA, (b a secondary assessment of dimensionality using a principal components analysis (PCA of the residuals when the items are fit to the Rasch model, and (c an assessment of item-level properties using item-level statistics provided when the items are fit to the Rasch model. The results support the usage of the scale as a supplement to high-stakes decision making such as tenure. However, the lack of precise targeting of item difficulty to person ability combined with the low person separation index renders rank-ordering professors according to minuscule differences in overall subscale scores a highly questionable practice.

    Discrepancy in quality of health care for patients with diverse backgrounds contributes to health outcome disparities. BSN students reveal surprise regarding the presence of health care disparities. Critical social theory guided this study. The psychometric properties of the Perception of Prejudice in Health Care Scale–Modified (PPHC-M) were evaluated,and the relationship between perceived discrimination in health care delivery and cultural sensitivity awareness was explored. A descriptive, cross-sectional survey of 146 Midwest BSN students was conducted using Cultural Competence Assessment (CCA), PPHC-M, and the Marlowe–Crowne Social Desirability Scale. PPHC-M demonstrated reliability(α = .781.) Cronbach’s alphas for General Perception of Prejudice (GPP) and Personal Experience of Prejudice (PEP) were.759 and .756, respectively. Construct validity was supported by contrasted groups. The PPHC was not significantly correlated with the CCA scores. PPHC-M shows promise in measuring perceived prejudice in health care.

    As quality of work-life (QWL) among nurses affects both patient care and institutional standards, assessment regarding QWL for the profession is important. Work-related Quality of Life Scale (WRQOLS) is a reliable QWL assessment tool for the nursing profession. To develop a Chinese version of the WRQOLS-2 and to examine its psychometric properties as an instrument to assess QWL for the nursing profession in China. Forward and back translating procedures were used to develop the Chinese version of WRQOLS-2. Six nursing experts participated in content validity evaluation and 352 registered nurses (RNs) participated in the tests. After a two-week interval, 70 of the RNs were retested. Structural validity was examined by principal components analysis and the Cronbach's alphas calculated. The respective independent sample t-test and intra-class correlation coefficient were used to analyze known-group validity and test-retest reliability. One item was rephrased for adaptation to Chinese organizational cultures. The content validity index of the scale was 0.98. Principal components analysis resulted in a seven-factor model, accounting for 62% of total variance, with Cronbach's alphas for subscales ranging from 0.71 to 0.88. Known-group validity was established in the assessment results of the participants in permanent employment vs. contract employment (t = 2.895, p < 0.01). Good test-retest reliability was observed (r = 0.88, p < 0.01). The translated Chinese version of the WRQOLS-2 has sufficient validity and reliability so that it can be used to evaluate the QWL among nurses in mainland China.

    Cultural competence of healthcare professionals (HCPs) is recognized as a strategy to reduce cultural disparities in healthcare. However, standardised, valid and reliable instruments to assess HCPs' cultural competence are notably lacking. The present study aims to 1) identify the core components of cultural competence from a healthcare perspective, 2) to develop a self-report instrument to assess cultural competence of HCPs and 3) to evaluate the psychometric properties of the new instrument. The conceptual model and initial item pool, which were applied to the cross-cultural competence instrument for the healthcare profession (CCCHP), were derived from an expert survey (n = 23), interviews with HCPs (n = 12), and a broad narrative review on assessment instruments and conceptual models of cultural competence. The item pool was reduced systematically, which resulted in a 59-item instrument. A sample of 336 psychologists, in advanced psychotherapeutic training, and 409 medical students participated, in order to evaluate the construct validity and reliability of the CCCHP. Construct validity was supported by principal component analysis, which led to a 32-item six-component solution with 50% of the total variance explained. The different dimensions of HCPs' cultural competence are: Cross-Cultural Motivation/Curiosity, Cross-Cultural Attitudes, Cross-Cultural Skills, Cross-Cultural Knowledge/Awareness and Cross-Cultural Emotions/Empathy. For the total instrument, the internal consistency reliability was .87 and the dimension's Cronbach's α ranged from .54 to .84. The discriminating power of the CCCHP was indicated by statistically significant mean differences in CCCHP subscale scores between predefined groups. The 32-item CCCHP exhibits acceptable psychometric properties, particularly content and construct validity to examine HCPs' cultural competence. The CCCHP with its five dimensions offers a comprehensive assessment of HCPs' cultural competence, and has the

    Since the use of the questionnaire to evaluate adherence to HIV therapy (acronym CEAT-VIH) has increased in the last decade and translation into new language versions has been requested, summarizing information regarding the psychometric properties of the instrument may be useful for researchers and practitioners. The purpose of this work was to review the psychometric properties of the questionnaire CEAT-VIH, available from published studies and research reports. Medline, PsycINFO, Google Scholar and Google; the searched period was from 2001 to 2012. Forty-eight research materials referring to the questionnaire CEAT-VIH were initially gathered from academic databases and direct contact with researchers, before being analyzed. From the initial pool of material compiled (i.e., abstracts, technical reports or database files, dissertations or complete articles), only 20 comprised original data. The selected research material described a variety of information in terms of the psychometric properties of the questionnaire. The results from the primary studies were then summarized in tables for evaluation, description and comparison. Thirteen out of 16 studies reported a Cronbach's alpha value of above 0.70, supporting the internal consistency reliability of the CEAT-VIH questionnaire. No floor or ceiling effects were observed. Hypothesized relationships between the CEAT-VIH score and adherence-related variables (e.g., viral load, CD4+, compliance evaluated by physician or pharmacist, complexity of treatment and pill numbers) were observed, indicating validity evidence. Thus, variables expected to act as psychological risk factors for low adherence (e.g., stress, depression and anxiety) or protector factor (e.g., social support) to good adherence were observed. The scores of the questionnaire were also related to quality of life outcomes. Moreover, patients that received adherence intervention showed increased CEAT-VIH adherence scores.

    Full Text Available This pilot study aimed to evaluate and examine an instrument that integrates relevant aspects of cross-sectoral (in- and outpatients mental health care, is simply to use and shows satisfactory psychometric properties. The development of the scale comprised literature research, held 14 focus groups and 12 interviews with patients and health care providers, item-pool generation, content validation by a scientific expert panel, and face validation by 90 patients. The preliminary scale was tested on 385 patients across seven German hospitals with cross-sectoral mental health care (CSMHC as part of their treatment program. Psychometric properties of the scale were evaluated using genuine and transformed data scoring. To check reliability and postdictive validity of the scale, Cronbach’s α coefficient and multivariable linear regression were used. This development process led to the development of an 18-item scale called the “Scale for Evaluation of Psychiatric Integrative and Continuous Care (SEPICC” with a two-point and five-point response options. The scale consists of two sections. The first section assesses the presence or absence of patients’ experiences with various CSMHC’ relevant components such as home treatment, flexibility of treatments’ switching, case management, continuity of care, cross-sectoral therapeutic groups, and multidisciplinary teams. The second section evaluates the patients’ opinions about these relevant components. Using raw and transformed scoring resulted into comparable results. However, data distribution using transformed scoring showed a smaller deviation from normality. For the overall scale, the Cronbach’s α coefficient was 0.82. Self-reported experiences with relevant components of the CSMHC were positively associated with the patients approval of these components. In conclusion, the new scale provides a good starting point for further validation. It can be used as a tool to evaluate CSMHC

    Full Text Available Abstract Background Prior studies on social capital and health have assessed social capital in residential neighbourhoods and communities, but the question whether the concept should also be applicable in workplaces has been raised. The present study reports on the psychometric properties of an 8-item measure of social capital at work. Methods Data were derived from the Finnish Public Sector Study (N = 48,592 collected in 2000–2002. Based on face validity, an expert unfamiliar with the data selected 8 questionnaire items from the available items for a scale of social capital. Reliability analysis included tests of internal consistency, item-total correlations, and within-unit (interrater agreement by rwg index. The associations with theoretically related and unrelated constructs were examined to assess convergent and divergent validity (construct validity. Criterion-related validity was explored with respect to self-rated health using multilevel logistic regression models. The effects of individual level and work unit level social capital were modelled on self-rated health. Results The internal consistency of the scale was good (Cronbach's alpha = 0.88. The rwg index was 0.88, which indicates a significant within-unit agreement. The scale was associated with, but not redundant to, conceptually close constructs such as procedural justice, job control, and effort-reward imbalance. Its associations with conceptually more distant concepts, such as trait anxiety and magnitude of change in work, were weaker. In multilevel models, significantly elevated age adjusted odds ratios (ORs of poor self-rated health (OR = 2.42, 95% confidence interval (CI: 2.24–2.61 for the women and OR = 2.99, 95% CI: 2.56–3.50 for the men were observed for the employees in the lowest vs. highest quartile of individual level social capital. In addition, low social capital at the work unit level was associated with a higher likelihood of poor self-rated health

    The Motor tic, Obsessions and compulsions, Vocal tic Evaluation Survey (MOVES) is a self-report scale suggested as a severity scale for tics and related sensory phenomena observed in Gilles de la Tourette syndrome (GTS) and recommended as a screening instrument by the Committee on Rating Scale Development of the International Parkinson's Disease and Movement Disorder Society. To cross-culturally adapt a French version of the MOVES and to evaluate its psychometric properties. After the cross-cultural adaptation of the MOVES, we assessed its psychometric properties in 53 patients aged 12-16 years and in 54 patients aged 16 years and above: reliability and construct validity (relationships between items and scales), internal consistency and concurrent validity with the Yale Global Tic Severity Scale (YGTSS) and the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) or the auto-Yale-Brown scale. The results showed very good acceptability with response rates greater than 92%, good internal consistency (Cronbach's alpha ranging from 0.62 and 0.89) and good test-retest reliability (ICCs ranging from 0.59 to 0.91). Concurrent validity with the YGTSS, CY-BOCS and auto-Yale-Brown scales showed strong expected correlations. The cut-off points tested for diagnostic performance gave satisfactory values of sensitivity, specificity, and positive and negative predictive values. Our study provides evidence of the good psychometric properties of the French version of the MOVES. The cross-cultural adaptation of this specific instrument will allow investigators to include French-speaking persons with GTS aged 12 years and over in national and international collaboration research projects.

    Full Text Available Body checking is considered an expression of an excessive preoccupation with appearance. The first aim of this study was to evaluate the psychometric properties of a Brazilian Portuguese version of the Body Checking Questionnaire (BCQ. Additionally, we wanted to examine the questionnaire's associations with body avoidance behaviour, body mass index, dietary habits, and the intensity, frequency, and length of physical exercise. Finally, we also examined the differences between the total BCQ score and the individual BCQ factor scores. Differences between active and sedentary persons and between non-dieters and those on weight-loss diets were also analyzed. For the psychometric study, 546 female public university students from four different courses were surveyed. Two minor samples of university students and eating disorders women were also recruited. In the second part of the study, 403 women were recruited from weight-loss programs, gyms, and a university. All participants were verbally invited to participate in the research and voluntarily took part. Confirmatory factor analysis showed a good fit to the original model of the Brazilian BCQ that retained all 23 items. Satisfactory evidence of construct validity and internal consistency were also generated through analysis of factor loadings, t-values, Cronbach's alpha, and construct reliability tests. The results also showed associations among body checking and body avoidance, body satisfaction, social anxiety, body mass index, and the frequency and intensity of physical exercise. Significant differences were found between non-dieters and weight-loss dieters for all BCQ factors and the total BCQ score. For physically active and sedentary persons, a significant difference was only observed for idiosyncratic checking behaviour. In conclusion, the BCQ appears to be a valid and reliable scale for Brazilian research, and the associations and differences found in this study suggest that women at gyms

    The Clinician-Administered PTSD Scale (CAPS) is an extensively validated and widely used structured diagnostic interview for posttraumatic stress disorder (PTSD). The CAPS was recently revised to correspond with PTSD criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). This article describes the development of the CAPS for DSM-5 (CAPS-5) and presents the results of an initial psychometric evaluation of CAPS-5 scores in 2 samples of military veterans (Ns = 165 and 207). CAPS-5 diagnosis demonstrated strong interrater reliability (к = .78 to 1.00, depending on the scoring rule) and test-retest reliability (к = .83), as well as strong correspondence with a diagnosis based on the CAPS for DSM-IV (CAPS-IV; к = .84 when optimally calibrated). CAPS-5 total severity score demonstrated high internal consistency (α = .88) and interrater reliability (ICC = .91) and good test-retest reliability (ICC = .78). It also demonstrated good convergent validity with total severity score on the CAPS-IV (r = .83) and PTSD Checklist for DSM-5 (r = .66) and good discriminant validity with measures of anxiety, depression, somatization, functional impairment, psychopathy, and alcohol abuse (rs = .02 to .54). Overall, these results indicate that the CAPS-5 is a psychometrically sound measure of DSM-5 PTSD diagnosis and symptom severity. Importantly, the CAPS-5 strongly corresponds with the CAPS-IV, which suggests that backward compatibility with the CAPS-IV was maintained and that the CAPS-5 provides continuity in evidence-based assessment of PTSD in the transition from DSM-IV to DSM-5 criteria.

    Objective. To translate the revised Michigan Diabetes Knowledge Test into the Arabic language and examine its psychometric properties. Setting. Of the 139 participants recruited through King Fahad Medical City in Riyadh, Saudi Arabia, 34 agreed to the second-round sample for retesting purposes. Methods. The translation process followed the World Health Organization's guidelines for the translation and adaptation of instruments. All translations were examined for their validity and reliability. Results. The translation process revealed excellent results throughout all stages. The Arabic version received 0.75 for internal consistency via Cronbach's alpha test and excellent outcomes in terms of the test-retest reliability of the instrument with a mean of 0.90 infraclass correlation coefficient. It also received positive content validity index scores. The item-level content validity index for all instrument scales fell between 0.83 and 1 with a mean scale-level index of 0.96. Conclusion. The Arabic version is proven to be a reliable and valid measure of patient's knowledge that is ready to be used in clinical practices. PMID:27995149

    This study examined the psychometric properties of the 19-item Thought–Action Fusion (TAF) Scale, a measure of maladaptive cognitive intrusions, in a large clinical sample (N = 700). An exploratory factor analysis (n = 300) yielded two interpretable factors: TAF Moral (TAF-M) and TAF Likelihood (TAF-L). A confirmatory bifactor analysis was conducted on the second portion of the sample (n = 400) to account for possible sources of item covariance using a general TAF factor (subsuming TAF-M) alongside the TAF-L domain-specific factor. The bifactor model provided an acceptable fit to the sample data. Results indicated that global TAF was more strongly associated with a measure of obsessive-compulsiveness than measures of general worry and depression, and the TAF-L dimension was more strongly related to obsessive-compulsiveness than depression. Overall, results support the bifactor structure of the TAF in a clinical sample and its close relationship to its neighboring obsessive-compulsiveness construct. PMID:22315482

    Full Text Available BACKGROUND: Self-efficacy has been shown to be a predictor of many health-related behaviors, including the practice of pelvic floor exercises with a focus on prevention or cure. OBJECTIVES: To describe the process of construction and the psychometric properties of the scale of self-efficacy for the practice of pelvic floor exercises (EAPEAP. METHOD: A cross-sectional study of validation was carried out with 81 from community and 96 postpartum women, 54.8% of them complained of urinary leakage. An exploratory factor analysis and internal consistency analysis was performed. To check predictive capacity, we analyzed the adherence at 3 months post - intervention and compared the scores of self-efficacy between adherent and non-adherent women. Reliability was analyzed by split half procedure. RESULTS: The instrument showed α=0.923, and revealed three factors: performance expectation considering the action, performance expectation considering the preparation for action and outcome expectations. These factors accounted for 65.32% of the total variance. The instrument was able to differentiate between women who adhere and have not adhered to the exercises (U=352, p=0.013 and there was strong correlation between the two halves of the instrument (rho=0.889, p<0.001. CONCLUSION: The scale is a valid and reliable tool to measure self-efficacy to practice pelvic floor exercises.

    The twenty-one item Stress Measurement of Female Marriage Immigrants (SMFMI) was developed to assess stress of female marriage immigrants in Korea. This study reports the psychometric properties of a revised SMFMI (SMFMI-R) for application with female marriage immigrants to Korea who were raising children. Participants were 190 female marriage immigrants from China, Vietnam, the Philippines, and other Asian countries, who were recruited using convenience sampling between November 2013 and December 2013. Survey questionnaires were translated into study participants' native languages (Chinese, Vietnamese, and English). Principal component analysis yielded nineteen items in four factors (family, parenting, cultural, and economic stress), explaining 63.5% of the variance, which was slightly better than the original scale. Confirmatory factor analysis indicated adequate fit for the four-factor model. Based on classic test theory and item response theory, strong support was provided for item discrimination, item difficulty, and internal consistency (Cronbach's alpha = 0.923). SMFMI-R scores were negatively associated with Korean proficiency and subjective economic status. The SMFMI-R is a valid, reliable, and comprehensive measure of stress for female marriage immigrants and can provide useful information to develop intervention programs for those who may be at risk for emotional stress.

    Intuitive eating is based on a strong physical connection with the body, aligned to internal cues of hunger and satiety, and a low preoccupation with food. The aim of this study was to provide a German version of the Intuitive Eating Scale-2 (IES-2) and to examine its psychometric properties with data collected from 532 participants aged 18-91 years. The IES-2 was translated into German following the World Health Organization guidelines (2016). Cronbach's alpha as a measure of internal consistency was 0.89 for the IES-2 total score, as well as 0.73 - 0.92 for the IES-2 subscale scores. For group differences, the results were as hypothesized: men had higher IES-2 scores than women, and participants with under- and average weight showed higher IES-2 scores than participants with overweight and obesity. Participants without a dieting history had higher IES-2 scores than former or current dieters. In line with our hypotheses regarding construct validity, the IES-2 score had negative associations with emotional eating, restraint eating, external eating, binge eating and eating disorder symptomatology, as well as positive associations with self-efficacy and mental health-related quality of life. Second-order confirmatory factor analysis replicated the four-factor solution, with intuitive eating as a higher-order factor. These findings demonstrate that the German version of the IES-2 is a useful tool to assess intuitive eating in the general German population. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The Guides of Good Practices (GGP) are necessary tools in the universal healthcare and in the clinical management, providing the user/patient with a major quality in the assistance, in order to optimize and reinforce an individualized attention into action, taking into account the best scientific evidence. The literature provides different references to the development of the GGP, but there is little knowledge about the attitude of professionals towards them, since most of the studies that exist are qualitative. Therefore, the aim of this work is to construct and validate a Likert scale which could assess the attitude of the nurse towards GGP. The methodology used was quantitative, descriptive, cross, opinion, anonymous and also it could validate a scale via the following measurements: content validation by experts, correlation between items, external reliability, internal consistency, stability and exploratory factor analysis. The result was a scale consisting of 20 items that refer to the attitude toward the GGP, with a percentage of agreement among experts over 75 % on all the items, and a significant Pearson correlation between the pre-test and post-test in all variables, but for three. The internal consistency measured by Cronbach's alpha was 0.878. These results are acceptable in terms of the psychometric characteristics of the instrument, with easy and fast administration and simple in their interpretation, allowing quantifying and generating knowledge about the attitudes of nurses towards GGP.

    Women's ability to broadly conceptualize beauty (i.e., perceive many looks, appearances, body sizes/shapes, and inner characteristics as beautiful) has been identified as a facet of positive body image in qualitative research. A scale is needed to be able to assess this construct within quantitative research. Therefore, we developed the Broad Conceptualization of Beauty Scale (BCBS), which measures the extent women define female beauty widely within external and internal characteristics, and examined its psychometric properties among four community samples totaling 1086 women. Exploratory and confirmatory factor analyses revealed a unidimensional structure with nine items. The internal consistency, test-retest reliability, and construct (convergent, discriminant, and incremental) validity of its scores were upheld. Researchers and clinicians can use the BCBS alone to assess women's perceptions of female beauty, or they can use the BCBS alongside women's perceptions of self-beauty to more comprehensively explore women's ability to broadly conceptualize beauty for others and themselves.

    Rationale The Drug Effects Questionnaire (DEQ) is widely used in studies of acute subjective response (SR) to a variety of substances, but the format of the DEQ varies widely across studies, and details of its psychometric properties are lacking. Thus, the field would benefit from demonstrating the reliability and validity of the DEQ for use across multiple substances. Objective The current study evaluated the psychometric properties of several variations of DEQ items, which assessed the extent to which participants (1) feel any substance effect(s), (2) feel high, (3) like the effects, (4) dislike the effects, and (5) want more of the substance using 100mm Visual Analog Scales. Methods DEQ data from three placebo-controlled studies were analyzed to examine SR to amphetamine, nicotine, and alcohol. We evaluated the internal structure of the DEQ for use with each substance as well as relationships between scale items, measures of similar constructs, and substance-related behaviors. Results Results provided preliminary psychometric support for items assessing each DEQ construct (FEEL, HIGH, DISLIKE, LIKE, and MORE). Conclusions Based on the study results, we identify several common limitations of extant variants of the DEQ and recommend an improved version of the measure. The simplicity and brevity of the DEQ combined with its promising psychometric properties support its use in future SR research across a variety of substances. PMID:23271193

    Full Text Available Background: The lack of reliable, valid and adequately standardized measures of mental illnesses in sub-Saharan Africa is a key challenge for epidemiological studies on mental health.  We evaluated the psychometric properties and feasibility of using a computerized version of the Major Depression Inventory (MDI in an epidemiological study in rural Kenya. Methods: We surveyed 1496 participants aged 13-24 years in Kilifi County, on the Kenyan coast. The MDI was administered using a computer-assisted system, available in three languages. Internal consistency was evaluated using both Cronbach’s alpha and the Omega Coefficient. Confirmatory factor analysis was performed to evaluate the factorial structure of the MDI. Results:  Internal consistency using both Cronbach’s Alpha (α= 0.83 and the Omega Coefficient (0.82; 95% confidence interval 0.81- 0.83 was above acceptable thresholds. Confirmatory factor analysis indicated a good fit of the data to a unidimensional model of MDI (χ2 (33, N = 1409 = 178.52 p < 0.001, TLI = 0.947, CFI = 0.961, and Root Mean Square Error of Approximation, RMSEA = .056, and this was confirmed using Item Response Models (Loevinger’s H coefficient 0.38 that proved the MDI was a unidimensional scale. Equivalence evaluation indicated invariance across sex and age groups. In our population, 3.6% of the youth presented with scores suggesting major depression using the ICD-10 scoring algorithm, and 8.7% presented with total scores indicating presence of depression (mild, moderate or severe.  Females and older youth were at the highest risk of depression. Conclusions: The MDI has good psychometric properties.  Given its brevity, relative ease of usage and ability to identify at-risk youth, it may be useful for epidemiological studies of depression in Africa.  Studies to establish clinical thresholds for depression are recommended. The high prevalence of depressive symptoms suggests that depression may be an important

    Full Text Available Music listening may serve many adaptive functions in everyday life. However, studies examining the relationship between the functions of music listening (FML and wellbeing outcomes have produced mixed findings. The purpose of this study is to develop a new measure to assess music listening functions that is psychometrically robust, and suitable for outcomes-based research on music listening and wellbeing. Scale items were developed based on a literature review and a prior qualitative enquiry. The items were reviewed by four content experts in music psychology and scale development. Scale structure was investigated by EFA and CFA in two large samples of participants (N = 1,191, 17–66 years, M = 22.04, SD = 6.23, 326 males. Tests of dimensionality revealed a 46-item scale with 11 factors for the Adaptive Functions of Music Listening (AFML scale. Namely, Stress Regulation, Anxiety Regulation, Anger Regulation, Loneliness Regulation, Rumination, Reminiscence, Strong Emotional Experiences, Awe and Appreciation, Cognitive Regulation, Identity, and Sleep FML. The scale and its subscales possess good internal consistency and construct validity. In line with theory and research on gender differences in FML, scores on factors representing affect regulation FML were significantly higher among female respondents. Supporting the concurrent validity of the AFML scale, factors were positively correlated with an existing measure of the FML—the Music USE questionnaire. Further evidence of construct validity derives from positive associations between affect regulation factor scores and level of reappraisal, and lack of association with suppression, as measured by the Emotion Regulation Questionnaire. Consistent with the view that adaptive FML are positively related to wellbeing, a number of factors, affect regulation factors in particular, were significantly positively correlated with subjective, psychological, and social wellbeing measures across two cross

    In epidemiological surveillance of mental health there is good reason to also include scales that measure the presence of well-being rather than merely symptoms of ill health. The Mental Health Continuum-Short Form (MHC-SF) is a self-reported scale to measure emotional, psychological and social well-being and conduct categorical diagnosis of positive mental health. This particular instrument includes the three core components of the World Health Organization's definition of mental health and had previously not been psychometrically evaluated on adolescents in China. In total 5,399 students (51.1% female) from schools in the urban areas of Weifang in China were included in the study (mean age = 15.13, SD = 1.56). Participants completed a comprehensive questionnaire with several scales, among them the MHC-SF. Statistical analyses to evaluate reliability, structural validity, measurement invariance, presence of floor and ceiling effects and to some extent external validity of the MHC-SF were carried out. The Cronbach's α coefficients for sub-scales as well as the total scale were all above 0.80 indicating good reliability. Confirmative factor analysis confirmed the three-dimensional structure of the Chinese version of MHC-SF and supported the configural and metric invariance across gender and age. Noteworthy ceiling effects were observed for single items and sub-scales although not for the total scale. More importantly, observed floor effects were negligible. The stronger correlation found between MHC-SF and Minneapolis-Manchester Quality of Life Instrument (as measure of positive mental health) than between MHC-SF and Hospital Anxiety Depression Scale (as measure of mental illness and distress) yielded support for external validity. In conclusion, the main findings of this study are in line with studies from other countries that evaluated the psychometric properties of the MHC-SF and show that this instrument, that includes the three core components of the

    High-pressure Freon blasting techniques are being evaluated for applications involving the removal of non-adherent radioactive particulate contamination at SRP. Very little waste is generated by this technique because the used Freon can be easily distilled and reused. One of the principle advantages of this technique is that decontaminated electrical equipment can be returned to service immediately without drying, unlike high-pressure water blasting techniques. Preliminary scoutin tests evaluating high-pressure Freon blasting for decontamination at SRP were carried out at Quadrex Co., Oak Ridge, TN, October 12 and 13. DWPF-type contamination (raw sludge plus volatiles) and separations area-type contamination (diluted boiling point (47.6 0 C) allow it to rapidly separate from higher boiling contaminants via distillation with filtration to remove particulate material, and distillation with condensation, the solvent may be recovered for indefinite reuse while reducing the radioactive waste to a minimum. 3 references, 5 figures, 6 tables

    The purpose of the study was to report initial data on the psychometric properties of the Brief Fear of Negative Evaluation Scale. The scale was applied to a nonclinical sample of 250 (137 women, 113 men) Turkish undergraduate students selected randomly from Middle East Technical University. Their mean age was 20.4 yr. (SD= 1.9). The factor structure of the Turkish version, its criterion validity, and internal reliability coefficients were assessed. Although maximum likelihood factor analysis initially indicated that the scale had only one factor, a forced two-factor solution accounted for more variance (61%) in scale scores than a single factor. The straightforward items loaded on the first factor, and the reverse-coded items loaded on the second factor. The total score was significantly positively correlated with scores on the Revised Cheek and Buss Shyness Scale and significantly negatively correlated with scores on the Rosenberg Self-Esteem Scale. Factor 1 (straightforward items) correlated more highly with both Shyness and Self-esteem than Factor 2 (reverse-coded items). Internal consistency estimate was .94 for the Total scores, .91 for the Factor 1 (straightforward items), and .87 for the Factor 2 (reverse-coded items). No sex differences were evident for Fear of Negative Evaluation.

    Background Cultural competence of healthcare professionals (HCPs) is recognized as a strategy to reduce cultural disparities in healthcare. However, standardised, valid and reliable instruments to assess HCPs’ cultural competence are notably lacking. The present study aims to 1) identify the core components of cultural competence from a healthcare perspective, 2) to develop a self-report instrument to assess cultural competence of HCPs and 3) to evaluate the psychometric properties of the new instrument. Methods The conceptual model and initial item pool, which were applied to the cross-cultural competence instrument for the healthcare profession (CCCHP), were derived from an expert survey (n = 23), interviews with HCPs (n = 12), and a broad narrative review on assessment instruments and conceptual models of cultural competence. The item pool was reduced systematically, which resulted in a 59-item instrument. A sample of 336 psychologists, in advanced psychotherapeutic training, and 409 medical students participated, in order to evaluate the construct validity and reliability of the CCCHP. Results Construct validity was supported by principal component analysis, which led to a 32-item six-component solution with 50% of the total variance explained. The different dimensions of HCPs’ cultural competence are: Cross-Cultural Motivation/Curiosity, Cross-Cultural Attitudes, Cross-Cultural Skills, Cross-Cultural Knowledge/Awareness and Cross-Cultural Emotions/Empathy. For the total instrument, the internal consistency reliability was .87 and the dimension’s Cronbach’s α ranged from .54 to .84. The discriminating power of the CCCHP was indicated by statistically significant mean differences in CCCHP subscale scores between predefined groups. Conclusions The 32-item CCCHP exhibits acceptable psychometric properties, particularly content and construct validity to examine HCPs’ cultural competence. The CCCHP with its five dimensions offers a comprehensive

    Full Text Available Orientation: The positive organisational behaviour movement emphasises the advantages of psychological strengths in business. The psychological virtues of positive emotional experiences can potentially promote human strengths to the advantages of business functioning and the management of work conditions. This is supported by Fredrickson’s broaden-and-build theory that emphasises the broadening of reactive thought patterns through experiences of positive emotions. Research purpose: A preliminary psychometric evaluation of a positive measurement of dimensions of emotional experiences in the workplace, by rephrasing the Kiefer and Barclay Toxic Emotional Experiences Scale. Motivation for the study: This quantitative Exploratory Factor Analysis investigates the factorial structure and reliability of the Positive Emotional Experiences Scale, a positive rephrased version of the Toxic Emotional Experiences Scale. Research approach, design and method: This Exploratory Factor Analysis indicates an acceptable three-factor model for the Positive Emotional Experiences Scale. These three factors are: (1 psychological recurrent positive state, (2 social connectedness and (3 physical refreshed energy, with strong Cronbach’s alphas of 0.91, 0.91 and 0.94, respectively. Main findings: The three-factor model of the Positive Emotional Experiences Scale provides a valid measure in support of Fredrickson’s theory of social, physical and psychological endured personal resources that build positive emotions. Practical/Managerial implications: Knowledge gained on positive versus negative emotional experiences could be applied by management to promote endured personal resources that strengthen positive emotional experiences. Contribution/value-add: The contribution of this rephrased Positive Emotional Experiences Scale provides a reliable measure of assessment of the social, physical and endured psychological and personal resources identified in Fredrickson

    Copping, Campbell, and Muncer (2014) have recently published an article critical of the psychometric approach to the assessment of life history (LH) strategy. Their purported goal was testing for the convergent validation and examining the psychometric structure of the High-K Strategy Scale (HKSS). As much of the literature on the psychometrics of human LH during the past decade or so has emanated from our research laboratory and those of close collaborators, we have prepared this detailed response. Our response is organized into four main sections: (1) A review of psychometric methods for the assessment of human LH strategy, expounding upon the essence of our approach; (2) our theoretical/conceptual concerns regarding the critique, addressing the broader issues raised by the critique regarding the latent and hierarchical structure of LH strategy; (3) our statistical/methodological concerns regarding the critique, examining the validity and persuasiveness of the empirical case made specifically against the HKSS; and (4) our recommendations for future research that we think might be helpful in closing the gap between the psychometric and biometric approaches to measurement in this area. Clearly stating our theoretical positions, describing our existing body of work, and acknowledgintheir limitations should assist future researchers in planning and implementing more informed and prudent empirical research that will synthesize the psychometric approach to the assessment of LH strategy with complementary methods.

    on the field-testing and psychometric evaluation of the item bank for cognitive functioning (CF). METHODS: In previous phases (I-III), 44 candidate items were developed measuring CF in cancer patients. In phase IV, these items were psychometrically evaluated in a large sample of international cancer patients...... model, showing an acceptable fit. Although several items showed DIF, these had a negligible impact on CF estimation. Measurement precision of the item bank was much higher than the two original QLQ-C30 CF items alone, across the whole continuum. Moreover, CAT measurement may on average reduce study...... sample sizes with about 35-40% compared to the original QLQ-C30 CF scale, without loss of power. CONCLUSION: A CF item bank for CAT measurement consisting of 34 items was established, applicable to various cancer patients across countries. This CAT measurement system will facilitate precise and efficient...

    To develop and psychometrically evaluate a questionnaire based on the outcome "Knowledge: Breast-feeding" of the Nursing Outcomes Classification (NOC) to determine the knowledge of parents on breast-feeding. The NOC outcome "Knowledge: Breast-feeding" allows for nurses/midwives to assess the efficacy of interventions aimed to improve the knowledge on breast-feeding in parents thought the clinical interview/observation. However, the use of self-administered questionnaires by patients could facilitate its evaluation. Two-phased study: (1) Development of the questionnaire based on experts' opinions; (2) Methodological design to assess its psychometric properties. The availability of tools that enable the determination of the knowledge of patients would facilitate nurses/midwives to set objectives, individualize interventions, and measure their effectiveness. © 2015 NANDA International, Inc.

    With China's rapid economic growth in the past few decades, there is currently an emerging focus on happiness. Cross-cultural validity studies have indicated that the four-item Subjective Happiness Scale (SHS) has high internal consistency and stable reliability. However, the psychometric characteristics of the SHS in broader Chinese community samples are unknown. We evaluated the factor structure and psychometric properties of the SHS in the Hong Kong general population. The Chinese SHS was derived using forward-backward translation. Of the Cantonese-speaking participants aged ≥15 years, 2,635 were randomly selected from the random sample component of the FAMILY Cohort, a territory-wide cohort study in Hong Kong. In addition to the SHS, a single-item overall happiness scale, the Patient Health Questionnaire-9 (PHQ-9), the Family Adaptation, Partnership, Growth, Affection, Resolve (APGAR) scale, and the Medical Outcomes Study 12-item short-form version 2 (SF-12) mental and physical health scales were administered. Exploratory and confirmatory factor analyses supported a single factor with high loadings for the four SHS items. Multiple group analyses indicated factor invariance across sex and age groups. Cronbach's alpha was 0.82, and 2-week test-retest reliability (n = 191) was 0.70. The SHS correlated significantly with single-item overall happiness (Spearman's rho [ρ] = 0.57), Family APGAR (ρ = 0.26), PHQ-9 (ρ = -0.34), and mental health-related quality of life (ρ = 0.40) but showed a lower correlation with physical health (ρ = 0.15). A regression model that included the PHQ-9 and Family APGAR scores explained 37% of the variance in SF-12 mental health scores; adding the SHS raised the variance explained to 41 %. Our results support the reliability and validity of the SHS as a relevant component in the measurement battery for mental well-being in a Chinese general population.

    Low adherence in recent HIV prevention clinical trials highlights the need to better understand, measure, and support product use within clinical trials. Conventional self-reported adherence instruments within HIV prevention trials, often relying on single-item questions, have proven ineffective. While objective adherence measures are desirable, none currently exist that apply to both active and placebo arms. Scales are composed of multiple items in the form of questions or statements that, when combined, measure a more complex construct that may not be directly observable. When psychometrically validated, such measures may better assess the multiple factors contributing to adherence/non-adherence. This study aimed to develop and psychometrically evaluate tools to screen and monitor trial participants' adherence to HIV prevention products within the context of clinical trial research. Based on an extensive literature review and conceptual framework, we identified and refined 86 items assessing potential predictors of adherence and 48 items assessing adherence experience. A structured survey, including adherence items and other variables, was administered to former ASPIRE and Ring Study participants and similar non-trial participants (n = 709). We conducted exploratory factor analyses (EFA) to identify a reduced set of constructs and items that could be used at screening to predict potential adherence, and at follow-up to monitor and intervene on adherence. We examined associations with other variables to assess content and construct validity. The EFA of screener items resulted in a 6-factor solution with acceptable to very good internal reliability (α: .62-.84). Similar to our conceptual framework, factors represent trial-related commitment (Distrust of Research and Commitment to Research); alignment with trial requirements (Visit Adherence and Trial Incompatibility); Belief in Trial Benefits and Partner Disclosure. The EFA on monitoring items resulted in 4

    We evaluated the psychometric properties of the Korean version of the Self-Efficacy for Exercise Scale (SEE-K). The SEE-K consists of nine items and was translated into Korean using the forward-backward translation method. We administered it to 212 community-dwelling older adults along with measures of outcome expectation for exercise, quality of life, and physical activity. The validity was determined using confirmatory factor analysis and Rasch analysis with INFIT and OUTFIT statistics, which showed acceptable model fit. The concurrent validity was confirmed according to positive correlations between the SEE-K, outcome expectation for exercise, and quality of life. Furthermore, the high physical activity group had higher SEE-K scores. Finally, the reliability of the SEE-K was deemed acceptable based on Cronbach's alpha, coefficients of determination, and person and item separation indices with reliability. Thus, the SEE-K appears to have satisfactory validity and reliability among older adults in South Korea. Copyright © 2015 Elsevier Inc. All rights reserved.

    This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions - Improvement (CGI-I) scale. Cronbach's alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment. Copyright © 2017.

    Self-management of osteoarthritis (OA) of the knee is important for treating this chronic disease. This study developed and psychometrically tested a new instrument for measuring adult patients' self-management needs of knee osteoarthritis (SMNKOA). The theoretical framework of self-care guided the development of the 35-item SMNKOA scale. Participants ( N = 372) were purposively sampled from orthopedic clinics at medical centers in Taiwan. The content validity index was 0.83. Principal components analysis identified a three-factor solution, accounting for 53.19% of the variance. The divergent validity was -0.67; convergent validity was -0.51. Cronbach's alpha was .95, Pearson's correlation coefficient was .88, and the intraclass correlation coefficient was .95. The scale's reliability and validity supports the SMNKOA, as a tool to measure self-management needs of adults with knee OA. Nurses and other health care providers can use this instrument to evaluate knee OA patients and identify strategies for improving health-related outcomes and patient education.

    In recent years Serious Games have evolved substantially, solving problems in diverse areas. In particular, in Cognitive Rehabilitation, Serious Games assume a relevant role. Traditional cognitive therapies are often considered repetitive and discouraging for patients and Serious Games can be used to create more dynamic rehabilitation processes, holding patients' attention throughout the process and motivating them during their road to recovery. This paper reviews Serious Games and user interfaces in rehabilitation area and details a Serious Games platform for Cognitive Rehabilitation that includes a set of features such as: natural and multimodal user interfaces and social features (competition, collaboration, and handicapping) which can contribute to augment the motivation of patients during the rehabilitation process. The web platform was tested with healthy subjects. Results of this preliminary evaluation show the motivation and the interest of the participants by playing the games.

    This Preliminary Safety Evaluation (PSE) describes and analyzes the installation and operation of the Plutonium Stabilization and Packaging System (SPS) at the Plutonium Finishing Plant (PFP). The SPS is a combination of components required to expedite the safe and timely storage of Plutonium (Pu) oxide. The SPS program will receive site Pu packages, process the Pu for storage, package the Pu into metallic containers, and safely store the containers in a specially modified storage vault. The location of the SPS will be in the 2736- ZB building and the storage vaults will be in the 2736-Z building of the PFP, as shown in Figure 1-1. The SPS will produce storage canisters that are larger than those currently used for Pu storage at the PFP. Therefore, the existing storage areas within the PFP secure vaults will require modification. Other modifications will be performed on the 2736-ZB building complex to facilitate the installation and operation of the SPS

    The removal of hydrogen isotopes from flowing gas streams is an important aspect of CTR technology for both decontamination and tritium recovery from plasma exhausts. Several getters have been evaluated for their tritium scrubbing potential at the parts per billion level. Measurements of total capacity and dynamic response have been made for barium, erbium, palladium dispersed on molecular sieve, General Electric H-36 (zirconium alloy), Union Carbide Y-993 (PdMnO 2 ), Societa Apparecchi Electtrici e Scientifici Getters ST101 (Zr--Al), ST171, and ST181, and a Sandia developed organic material, dimerized phenyl propargyl ether (DPPE). Preliminary flow studies were conducted by passing mixtures of either hydrogen or deuterium diluted with argon through packed beds containing the getter and periodically sampling the effluent with a gas chromatograph sensitive to 500 ppB H 2 . The results of this work, similar flow experiments using tritium and total capacity measurements are presented in the text

    The objectives of this systematic review were 1) to identify studies that assess the psychometric performance of the English-language version of 35 generic multidimensional patient-reported outcome measures (PROMs) for children and young people in general populations and evaluate their quality and 2) to summarize the psychometric properties of each PROM. MEDLINE, EMBASE, and PsycINFO were searched. The methodological quality of the articles was assessed using the COnsensus-based Standards for selection of health Measurement INstruments checklist. For each PROM, extracted evidence of content validity, construct validity, internal consistency, test-retest reliability, proxy reliability, responsiveness, and precision was judged against standardized reference criteria. We found no evidence for 14 PROMs. For the remaining 21 PROMs, 90 studies were identified. The methodological quality of most studies was fair. Quality was generally rated higher in more recent studies. Not reporting how missing data were handled was the most common reason for downgrading the quality. None of the 21 PROMs has had all psychometric properties evaluated; data on construct validity and internal consistency were most frequently reported. Overall, consistent positive findings for at least five psychometric properties were found for Child Health and Illness Profile, Healthy Pathways, KIDSCREEN, and Multi-dimensional Student Life Satisfaction Scale. None of the PROMs had been evaluated for responsiveness to detect change in general populations. Further well-designed studies with transparent reporting of methods and results are required.

    A preliminary evaluation of removing spent nuclear fuel (SNF) from 13 shutdown nuclear power reactor sites was conducted. At these shutdown sites the nuclear power reactors have been permanently shut down and the sites have been decommissioned or are undergoing decommissioning. The shutdown sites were Maine Yankee, Yankee Rowe, Connecticut Yankee, Humboldt Bay, Big Rock Point, Rancho Seco, Trojan, La Crosse, Zion, Crystal River, Kewaunee, San Onofre, and Vermont Yankee. The evaluation was divided into four components: (1) characterization of the SNF and greater-than-Class C low-level radioactive waste (GTCC waste) inventory, (2) a description of the on-site infrastructure and conditions relevant to transportation of SNF and GTCC waste, (3) an evaluation of the near-site transportation infrastructure and experience relevant to shipping transportation casks containing SNF and GTCC waste, including identification of gaps in information, and (4) an evaluation of the actions necessary to prepare for and remove SNF and GTCC waste. Every site was found to have at least one off-site transportation mode option for removing its SNF and GTCC waste; some have multiple options. Experience removing large components during reactor decommissioning provided an important source of information used to identify the transportation mode options for the sites. Especially important in conducting the evaluation were site visits, through which information was obtained that would not have been available otherwise. Extensive photographs taken during the site visits proved to be particularly useful in documenting the current conditions at or near the sites. It is expected that additional site visits will be conducted to add to the information presented in the evaluation.

    The probabilistic seismic hazard analysis (PSHA) is a methodology by which one evaluates the probability of exceeding different parameters of the ground motions (the maximum ground acceleration - PGA and the ground response spectrum - SA) as effect of the seismic action, on a given site at a future time moment. Due to the large uncertainties in the geological, geophysical, seismological input data, as well as, in the models utilised, various interpretation schemes are applied in the PSHA analyses. This interpretation schemes lead to opinion discrepancies among specialists which finally lead to disagreements in estimating the values of the seismic design for a given site. In order to re-evaluate the methodology and to improve the PSHA result stability, U.S. Nuclear Regulatory Commission (NRC), U.S. Department of Energy (DOE) and Electric Power Research Institute (EPRI) sponsored a project for defining methodological guides of performing PSHA analyses. The project was implemented by a panel of 7 experts, the Senior Seismic Hazard Analysis Committee - SSHAC. This paper presents a preliminary evaluation of the seismic hazard for the Cernavoda NPP site by application of the methodology mentioned, by taking into account the possible sources which could affect the site (the Vrancea focus, Galati - Tulcea fault, Sabla - Dulovo fault and local earthquakes)

    The cost of oil sands projects varies significantly. While costs have escalated considerably over the past few years, oil prices have gone significantly higher. This report provided an economic evaluation of the current fiscal terms applicable to Alberta oil sands. The analysis was done to evaluate the profitability of oil sand projects to investors under current conditions based on the generic royalty regime based on bitumen values. The objective of the royalty review was to determine whether Albertans received a fair share from their oil and gas resources. It discussed the wide variety of oil sands projects in Alberta using five case studies as examples. Cases involving steam assisted gravity drainage (SAGD) operations were assessed for both the Athabasca Mine and Cold Lake. The report provided a discussion of the economic assumptions including economic cases as well as production, costs and price data. It then provided the preliminary results of the economic-fiscal evaluation from the investor perspective including profitability indicators; international comparisons; internal rate of return; and net present value. The government perspective was also discussed with reference to attractiveness indicators; royalties as a percentage of bitumen values; and non-discounted and discounted government take. A royalty and tax feature analysis was also provided. Several issues for possible further review were also presented. tabs

    Full Text Available BACKGROUND: The current investigation examined the psychometric properties of the Internalized Stigma of Mental Illness (ISMI scale in a sample of patients with mental illness. In addition to the internal consistency, test-retest reliability, and concurrent validity that previous studies have tested for the ISMI, we extended the evaluation to its construct validity and measurement invariance using confirmatory factor analysis (CFA. METHODS: Three hundred forty-seven participants completed two questionnaires (i.e., the ISMI and the Depression and Somatic Symptoms Scale [DSSS], and 162 filled out the ISMI again after 50.23±31.18 days. RESULTS: The results of this study confirmed the frame structure of the ISMI; however, the Stigma Resistance subscale in the ISMI seemed weak. In addition, internal consistency, test-retest reliability, and concurrent validity were all satisfactory for all subscales and the total score of the ISMI, except for Stigma Resistance (α = 0.66; ICC = 0.52, and r = 0.02 to 0.06 with DSSS. Therefore, we hypothesize that Stigma Resistance is a new concept rather than a concept in internalized stigma. The acceptable fit indices supported the measurement invariance of the ISMI across time, and suggested that people with mental illness interpret the ISMI items the same at different times. CONCLUSION: The clinical implication of our finding is that clinicians, when they design interventions, may want to use the valid and reliable ISMI without the Stigma Resistance subscale to evaluate the internalized stigma of people with mental illness.

    This report fulfills the M2 milestone M2FT-13PN0912022, “Stranded Sites De-Inventorying Report.” In January 2013, the U.S. Department of Energy (DOE) issued the Strategy for the Management and Disposal of Used Nuclear Fuel and High-Level Radioactive Waste (DOE 2013). Among the elements contained in this strategy is an initial focus on accepting used nuclear fuel from shutdown reactor sites. This focus is consistent with the recommendations of the Blue Ribbon Commission on America’s Nuclear Future, which identified removal of stranded used nuclear fuel at shutdown sites as a priority so that these sites may be completely decommissioned and put to other beneficial uses (BRC 2012). Shutdown sites are defined as those commercial nuclear power reactor sites where the nuclear power reactors have been shut down and the site has been decommissioned or is undergoing decommissioning. In this report, a preliminary evaluation of removing used nuclear fuel from 12 shutdown sites was conducted. The shutdown sites were Maine Yankee, Yankee Rowe, Connecticut Yankee, Humboldt Bay, Big Rock Point, Rancho Seco, Trojan, La Crosse, Zion, Crystal River, Kewaunee, and San Onofre. These sites have no other operating nuclear power reactors at their sites and have also notified the U.S. Nuclear Regulatory Commission that their reactors have permanently ceased power operations and that nuclear fuel has been permanently removed from their reactor vessels. Shutdown reactors at sites having other operating reactors are not included in this evaluation.

    The purpose of Thermal Insulation Characterization Testing is to provide physical data to support certain assumptions and calculational techniques used in the criticality safety calculations in Section 6 of the Safety Analysis Reports for Packaging (SARPs) for drum-type packaging for Department of Energy's (DOE) Oak Ridge Y-12 Plant, managed by Martin Marietta Energy Systems, Inc. Results of preliminary data evaluation regarding the fire-test condition reveal that realistic weight loss consideration and residual material characterization in developing calculational models for the hypothetical accident condition is necessary in order to prevent placement of unduly conservative restrictions on shipping requirements as a result of overly conservative modeling. This is particularly important for fast systems. Determination of the geometric arrangement of residual material is of secondary importance. Both the methodology used to determine the minimum thermal insulation mass remaining after the fire test and the treatment of the thermal insulation in the criticality safety calculational models requires additional evaluation. Specific testing to be conducted will provide experimental data with which to validate the mass estimates and calculational modeling techniques for extrapolation to generic drum-type containers

    Full Text Available Abstract Background The 20-item Subjective Well-Being Under Neuroleptic Treatment Scale (SWN-20 is a self-report scale developed in order to assess the well-being of patients receiving antipsychotic medication independent of the improvement in their psychotic symptoms. The current study reports on the reliability and the psychometric properties of the Greek translation of the SWN-20. Methods A total of 100 inpatients or outpatients with schizophrenia (79 males and 21 females, aged 42.6 ± 11.35 years old from 3 different facilities were assessed with the Positive and Negative Symptoms Scale (PANSS, the Calgary Depression Scale and the Simpson-Angus Scale, and completed the SWN-20. The statistical analysis included the calculation of Pearson product moment correlation coefficient, the Cronbach α and factor analysis with Varimax normalised rotation. Results The SWN-20 had an α value equal to 0.79 and all the items were equal. The factor analysis revealed the presence of seven factors explaining 66% of total variance. The correlation matrix revealed a moderate relationship of the SWN-20 and its factors with the PANSS-Negative (PANSS-N, PANSS-General Psychopathology (PANSS-G, the Simpson-Angus and the Calgary scales, and no relationship to age, education and income class. Discussion The Greek translation of the SWN-20 is reliable, with psychometric properties close to the original scale.

    The Swedish Social Insurance Administration has developed a new assessment tool for sickness insurance. This study is a part of the initial evaluation of the application, called the Assessment of Work Performance, Structured Activities, and focuses on evaluation of the psychometric properties of social validity, content validity, and utility. This was a qualitative study using semi-structured telephone interviews with occupational therapists. A convenience sample was used and participants who fulfilled inclusion criteria (n = 15) were interviewed. Data were analyzed using content analysis with a directed approach. The results indicate that the application provides valuable information and that it is socially valid. Assessors found work tasks suitable for a diverse group of clients and reported that clients accepted the assessments. Improvements were suggested, for example, expanding the application with more work tasks. The instrument has benefits; however, further development is desired. The use of a constructed environment in assessments may be a necessary option to supplement a real environment. But depending on organizational factors such as time and other resources, the participants had different opportunities to do so. Further evaluations regarding ecological validity are essential to ensure that assessments are fair and realistic when using constructed environments. Implications for rehabilitation This study indicates that assessment in a constructed environment can provide a secure and protected context for clients being assessed. Psychometric evaluations are a never-ending process and this assessment instrument needs further development. However, this initial evaluation provides guidance in development of the instrument but also what studies to give priority to. It is important to evaluate social validity in order to ensure that clients and assessors perceive assessment methods fair and meaningful. In this study, participants found the work tasks

    The present study applied item response theory to examine the psychometric properties of the Asian Adolescent Depression Scale and to construct a short form among 1,084 teenagers recruited from secondary schools in Hong Kong. Findings suggested that some items of the full form reflected higher levels of severity and were more discriminating than others, and the Asian Adolescent Depression Scale was useful in measuring a broad range of depressive severity in community youths. Differential item functioning emerged in several items where females reported higher depressive severity than males. In the short form construction, preliminary validation suggested that, relative to the 20-item full form, our derived short form offered significantly greater diagnostic performance and stronger discriminatory ability in differentiating depressed and nondepressed groups, and simultaneously maintained adequate measurement precision with a reduced response burden in assessing depression in the Asian adolescents. Cultural variance in depressive symptomatology and clinical implications are discussed.

    Background Despite its importance as a paradigmatic personality disorder, little is known about the measurement invariance of the DSM-IV borderline personality disorder (BPD) criteria ; that is, whether the criteria assess the disorder equivalently across different groups. Method BPD criteria were evaluated at interview in 2794 young adult Norwegian twins. Analyses, based on item-response modeling, were conducted to test for differential age and sex moderation of the individual BPD criteria characteristics given factor-level covariate effects. Results Confirmatory factor analytic results supported a unidimensional structure for the nine BPD criteria. Compared to males, females had a higher BPD factor mean, larger factor variance and there was a significant age by sex interaction on the factor mean. Strong differential sex and age by sex interaction effects were found for the ‘ impulsivity ’ criterion factor loading and threshold. Impulsivity related to the BPD factor poorly in young females but improved significantly in older females. Males reported more impulsivity compared to females and this difference increased with age. The ‘ affective instability ’ threshold was also moderated, with males reporting less than expected. Conclusions The results suggest the DSM-IV BPD ‘ impulsivity ’ and ‘ affective instability ’ criteria function differentially with respect to age and sex, with impulsivity being especially problematic. If verified, these findings have important implications for the interpretation of prior research with these criteria. These non-invariant age and sex effects may be identifying criteria-level expression features relevant to BPD nosology and etiology. Criterion functioning assessed using modern psychometric methods should be considered in the development of DSM-V. PMID:19400977

    This study aims to develop a valid and reliable chronic kidney disease self-management instrument (CKD-SM) for assessing early stage chronic kidney disease patients' self-management behaviours. Enhancing early stage chronic kidney disease patients' self-management plays a key role in delaying the progression of chronic kidney disease. Healthcare provider understanding of early stage chronic kidney disease patients' self-management behaviours can help develop effective interventions. A valid and reliable instrument for measuring chronic kidney disease patients' self-management behaviours is needed. A cross-sectional descriptive study collected data for principal components analysis with oblique rotation. Mandarin- or Taiwanese-speaking adults with chronic kidney disease (n=252) from two medical centres and one regional hospital in Southern Taiwan completed the CKD-SM. Construct validity was evaluated by exploratory factor analysis. Internal consistency and test-retest reliability were estimated by Cronbach's alpha and Pearson correlation coefficients. Four factors were extracted and labelled self-integration, problem-solving, seeking social support and adherence to recommended regimen. The four factors accounted for 60.51% of the total variance. Each factor showed acceptable internal reliability with Cronbach's alpha from 0.77-0.92. The test-retest correlations for the CKD-SM was 0.72. The psychometric quality of the CKD-SM instrument was satisfactory. Research to conduct a confirmatory factor analysis to further validate this new instrument's construct validity is recommended. The CKD-SM instrument is useful for clinicians who wish to identify the problems with self-management among chronic kidney disease patients early. Self-management assessment will be helpful to develop intervention tailored to the needs of the chronic kidney disease population. © 2013 Blackwell Publishing Ltd.

    Full Text Available The aim of the current study was to evaluate the psychometric characteristics (i.e., the validity and the reliability of the Short Inventory on Stress and Well-being (S-ISW, in particular the part of the S-ISW that measures well-being. The S-ISW is developed by ISW Limits in both Dutch and French and measures the following well-being indicators: strain, motivation and negative acts at work, which can be considered as possible outcome variables or employees’ reactions to the perceived work situation. Four samples (N1 = 17,781; N2 = 462; N3 = 264; N4 = 3596 were used to perform analyses, with longitudinal data available for Sample 2 and 3. The results supported the three-factor structure of the S-ISW (factor validity and the invariance of this factor structure between the Dutch and the French S-ISW. Furthermore, we established the content similarity of strain and motivation with negative stress and positive stress, respectively, supporting the construct validity of the S-ISW. The predictive validity of the well-being indicators was established using measures of absenteeism and doctor consultations. Finally, the S-ISW was reliable, as the indicators of well-being showed high test-retest reliability and adequate internal consistency. The part of the S-ISW that measures well-being is thus both valid and reliable, and may be a helpful instrument in conducting research to aid organizations in the development of their well-being policy.

    Satisfaction with continuing education can be defined as positive attitudes towards educational programs, which has potential to strengthen learning outcomes. A multi-dimensional construct may enhance continuing education program evaluation processes. The objective is to describe the development and psychometric testing of the 'affective - behavioral - cognitive - satisfaction questionnaire' (ABC-SAT) for assessing participants' satisfaction with a continuing education program for nurses in infection control. The multi-staged development of a satisfaction questionnaire comprised of three subscales. The pilot tool was administered to a nationwide sample of 126 infection control nurses to assess satisfaction after participating in a continuing education program. Satisfaction scores were calculated and psychometric testing was performed to determine reliability, using Cronbach's alpha, face validity, objectivity, and economy. A principle component analysis using varimax rotation and Kaiser normalization was performed. The analysis led to a three-factor solution of the questionnaire with 11 items, explaining 61.4% of the variance. Internal consistency of three scales using Cronbach's alpha was 0.83, 0.60, and 0.66, respectively. Selectivity coefficients varied between 0.39 and 0.70. Participants needed approximately three minutes to complete the questionnaire. Initial findings refer to a satisfying scale structure and internal consistency of the 3-dimensional ABC-SAT questionnaire. Further research is required to confirm the questionnaires' psychometric properties. Copyright © 2018 Elsevier Ltd. All rights reserved.

    This report describes a preliminary evaluation of the shielding design of FY98 KALIMER. The KALIMER shielding design includes the Inner Fixed Shield of a stainless cylinder located inside the support barrel; the Radial PSDRS Shields which are three B{sub 4}C cylinders located outside the support barrel at core level; the Lower IHX shield of a cylindrical B{sub 4}C plate located above the flow guide; and Inner and Outer IHX shields of B{sub 4}C cylinders located inside and outside of the support barrel, respectively. The DORT3.1 two-dimensional transport code was used to evaluate the KALIMER shielding design. The reactor system was represented by four axial zones, each of which was modeled in the R-Z geometry. The KAFAX-F22 library was used in the analyses, which was generated from the JEF-2.2 of OECD/NEA files for LMR applications by KAERI. The performance of the KALIMER shielding design is compared against the shielding design criteria. The results indicate that the support barrel, upper grid plate, and other reactor structures meet the maximum neutron fluence and DPA limits established in the shielding design criteria. Activities of the air effluent in the PSDRS were also evaluated and are shown to satisfy the maximum permissible concentration (MPC) limits in 10 CFR Part 20. In the future, the validation of the DORT model by a detailed three dimensional calculation such as MCNP and the justification of the current shielding design limits are needed.

    Meal pattern is an important variable in both obesity treatment and treatment for eating disorders. Momentary assessment and eating diaries are highly valid measurement methods but often cumbersome and not always feasible to use in clinical practice. The aim of this study was to design and evaluate a self-report instrument for measuring meal patterns. The Pattern of eating item from the Eating Disorder Examination (EDE) interview was adapted to self-report format to follow the same overall structure as the Eating Disorder Examination Questionnaire. The new instrument was named the Meal Patterns Questionnaire (MPQ) and was compared with the EDE in a student sample (n=105) and an obese sample (n=111). The individual items of the MPQ and the EDE showed moderate to high correlations (rho=.63-89) in the two samples. Significant differences between the MPQ and EDE were only found for two items in the obese sample. The total scores correlated to a high degree (rho=.87/.74) in both samples and no significant differences were found in this variable. The MPQ can provide an overall picture of a person's eating patterns and is a valid way to collect data regarding meal patterns. The MPQ may be a useable tool in clinical practice and research studies when more extensive instruments cannot be used. Future studies should evaluate the MPQ in diverse cultural populations and with more ecological assessment methods. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To evaluate the preliminary validity and reliability of the myTREEHOUSE Self-Concept Assessment for children with cerebral palsy (CP) aged 8 to 12 years. The myTREEHOUSE Self-Concept Assessment includes 26 items divided into eight domains, assessed across three Performance Perspectives (Personal, Social, and Perceived) and an additional Importance Rating. Face and content validity was assessed by semi-structured interviews with seven expert professionals regarding the assessment construct, content, and clinical utility. Reliability was assessed with 50 children aged 8 to 12 years with CP (29 males, 21 females; mean age 10y 2mo; Gross Motor Function Classification System [GMFCS] level I=35, II=8, III=5, IV=1; mean Wechsler Intelligence Scale for Children - Fourth Edition [WISC-IV]=104), whose data was used to calculate internal consistency of the scale, and a subset of 35 children (20 males, 15 females; mean age 10y 5mo; GMFCS level I=26, II=4, III=4, IV=1; mean WISC-IV=103) who participated in test-retest reliability within 14 to 28 days. Face and content validity was supported by positive expert feedback, with only minor adjustments suggested to clarify the wording of some items. After these amendments, strong internal consistency (Cronbach's α 0.84-0.91) and moderate to good test-retest reliability (intraclass correlation coefficient 0.64-0.75) was found for each component. The myTREEHOUSE Self-Concept Assessment is a valid and reliable assessment of self-concept for children with CP aged 8 to 12 years. © 2017 Mac Keith Press.

The immunogenicity of these two vaccines, named Ad5.ZIKV-Efl and ZIKV-rEfl, was tested in C57BL/6 mice. Prime/boost immunization regimen was associated with induction of a ZIKV-specific antibody response, which provided neutralizing immunity. Moreover, protection was evaluated in seven-day-old pups after virulent ZIKV intraperitoneal challenge. Pups born to mice immunized with Ad5.ZIKV-Efl were all protected against lethal challenge infection without weight loss or neurological signs, while pups born to dams immunized with MNA-ZIKV-rEfl were partially protected (50%. No protection was seen in pups born to phosphate buffered saline-immunized mice. This study illustrates the preliminary efficacy of the E ZIKV antigen vaccination in controlling ZIKV infectivity, providing a promising candidate vaccine and antigen format for the prevention of Zika virus disease.

The medical therapy reactor (MTR) has a maximum power level of 10 MW(thermal) and utilizes 45 wt% uranium in UZrH, 20 wt% 235 U enriched hydride fuel matrix with 1 wt% erbium, which is a burnable poison and provides prompt negative reactivity feedback. The facility has five beam ports for patient treatment and advanced neutron beam research and is capable of 2,000 to 10,000 treatments per year, assuming single 8h/day, 5 day/week operation. The epithermal treatment flux from the beam ports is large, enabling single-session treatment of brain cancers of <10-min duration, with minimal fast neutron and gamma contaminants. The reactor core is designed with sufficient excess reactivity to yield a core lifetime equal to a facility lifetime of 30 yr. A preliminary safety evaluation was performed using the RELAP5 thermal-hydraulic code. The analysis addressed accidents in several major categories, including a pump coastdown, a loss of secondary heat sink, and a $0.5 step reactivity insertion

    The risk that a worker has found on the job is a function of the hazards present and his exposure level to those hazards. Exposure and risk assessment is therefore the heart of all occupational health and industrial hygiene programs involving a continuous process of information gathering. The use of a systematic method to characterize workplace exposures to chemical, physical and biological risks is a fundamental part of this process. This study aims to carry out a preliminary evaluation in a radioactive facility, identifying potential exposures and consequently the existing occupational hazards (risk/agent) in the workplace which the employee is subject. The study is based on proposal to carry out a basic characterization of the facility, which could be the first step in the investigation of occupational exposure. For this study was essential to know the workplace, potential risks and agents; workforce profile including assignment of tasks, sources of exposure processes, and control measures. The main tool used in this study was based on references, records, standards, procedures, interviews with the workers and with management. Since the basic characterization of the facility has been carried out, consequently the potential exposure to the agents of risks to workers has been identified. The study provided an overview of the perception of risk founded at facility studied. It is expected to contribute with the occupational health program resources for welfare of the worker. (author)

    This paper reports on the design of a prototype in-vivo Stokes polarimetry probe for skin lesion evaluation, and preliminary results from skin phantom and clinical trials of this device. The probe releases a single millisecond-long pulse from a laser diode with either linear or circular polarization. It then captures the resulting backscattered far-field polarization speckle and calculates the Stokes parameters. This probe was designed with three novel innovations in mind. First, the Stokes vector is captured quickly, using low-cost components without the use of moving parts. Second, a compact collimated laser diode was used as the light source. Third, the device and detector geometry were designed to produce and capture a uniform speckle field. In the first clinical trial of this device, measurements were taken from a variety of skin lesions, both cancerous and benign. The Stokes vector was measured and used to calculate the degree of polarization (DOP), the azimuth angle, and the ellipticity angle of the polarization ellipse for two input light polarizations. Among other findings, the DOP for circular polarized input light was consistently lower than the DOP for linear polarized input light. These findings indicate the potential for a fast and low-cost in-vivo skin cancer screening tool, and encourages the continuing development of this probe's techniques.

    The National Ecological Observatory Network (NEON) is an ambitious National Science Foundation sponsored project intended to accumulate and disseminate ecologically informative sensor data from sites among 20 distinct biomes found within the United States and Puerto Rico over a period of at least 30 years. These data are expected to provide valuable insights into the ecological impacts of climate change, land-use change, and invasive species in these various biomes, and thereby provide a scientific foundation for the decisions of future national, regional, and local policy makers. NEON's objectives are of substantial national and international importance, yet they must be achieved with limited resources. Sandia National Laboratories was therefore contracted to examine four areas of significant systems engineering concern; specifically, alternatives to commercial electrical utility power for remote operations, approaches to data acquisition and local data handling, protocols for secure long-distance data transmission, and processes and procedures for the introduction of new instruments and continuous improvement of the sensor network. The results of these preliminary systems engineering evaluations are presented, with a series of recommendations intended to optimize the efficiency and probability of long-term success for the NEON enterprise.

    Background An instrument should have been developed to measure participation as one possible criterion to evaluate inclusion of elderly people with intellectual disability. The ICF was utilized, because participation is one part of health related functioning, respectively disability. Furthermore ICF includes environmental factors (contextual factors) and attaches them an essentially influence on health related functioning, in particular on participation. Thus ICF Checklist additionally identifies environmental barriers for elimination. Methodology A linking process with VINELAND-II yielded 138 ICF items for the Checklist. The sample consists of 50 persons with a light or moderate intellectual disability. Two-thirds are female and the average age is 68. They were directly asked about their perceived quality of life. Additionally, proxy interviews were carried out with responsible staff members concerning necessary support and behavioral deviances. The ICF Checklist was administered twice, once (t2) the current staff member should rate health related functioning at the given time and in addition, a staff member who knows the person at least 10 years before (t1) should rate the former functioning. Content validity was investigated with factor analysis and criterion validity with correlational analysis related to supports need, behavioral deviances and perceived quality of life. Quantitative analysis was validated by qualitative content analysis of patient documentation. Results Factor analysis shows logical variable clusters across the extracted factors but neither interpretable factors. The Checklist is reliable, valid related to the chosen criterions and shows the expected age-related shifts. Qualitative analysis corresponds with quantitative data. Consequences/Conclusion ICF Checklist is appropriate to manage and evaluate patient-centered care. © Georg Thieme Verlag KG Stuttgart · New York.

  17. Psychometrics in action, science as practice.

    2017-07-27

    Practitioners in health sciences education and assessment regularly use a range of psychometric techniques to analyse data, evaluate models, and make crucial progression decisions regarding student learning. However, a recent editorial entitled "Is Psychometrics Science?" highlighted some core epistemological and practical problems in psychometrics, and brought its legitimacy into question. This paper attempts to address these issues by applying some key ideas from history and philosophy of science (HPS) discourse. I present some of the conceptual developments in HPS that have bearing on the psychometrics debate. Next, by shifting the focus onto what constitutes the practice of science, I discuss psychometrics in action. Some incorrectly conceptualize science as an assemblage of truths, rather than an assemblage of tools and goals. Psychometrics, however, seems to be an assemblage of methods and techniques. Psychometrics in action represents a range of practices using specific tools in specific contexts. This does not render the practice of psychometrics meaningless or futile. Engaging in debates about whether or not we should regard psychometrics as 'scientific' is, however, a fruitless enterprise. The key question and focus should be whether, on what grounds, and in what contexts, the existing methods and techniques used by psychometricians can be justified or criticized.

    To conduct a systematic review of the psychometric properties (reliability, validity and responsiveness) of self-report questionnaires used to assess symptoms and functional limitations of individuals with rotator cuff (RC) disorders. A systematic search in three databases (Cinahl, Medline and Embase) was conducted. Data extraction and critical methodological appraisal were performed independently by three raters using structured tools, and agreement was achieved by consensus. A descriptive synthesis was performed. One-hundred and twenty articles reporting on 11 questionnaires were included. All questionnaires were highly reliable and responsive to change, and showed construct validity; seven questionnaires also shown known-group validity. The minimal detectable change ranged from 6.4% to 20.8% of total score; only two questionnaires (American Shoulder and Elbow Surgeon questionnaire [ASES] and Upper Limb Functional Index [ULFI]) had a measurement error below 10% of global score. Minimal clinically important differences were established for eight questionnaires, and ranged from 8% to 20% of total score. Overall, included questionnaires showed acceptable psychometric properties for individuals with RC disorders. The ASES and ULFI have the smallest absolute error of measurement, while the Western Ontario RC Index is one of the most responsive questionnaires for individuals suffering from RC disorders. All included questionnaires are reliable, valid and responsive for the evaluation of individuals with RC disorders. As all included questionnaires showed good psychometric properties for the targeted population, the choice should be made according to the purpose of the evaluation and to the construct being evaluated by the questionnaire. The WORC, a RC-specific questionnaire, appeared to be more responsive. It should therefore be used to evaluate change in time. If the evaluation is time-limited, shorter questionnaires or short versions should be considered (such as

To confirm the factor structure of the Spanish version of the MPI-SCI (MPI-SCI-S, Multidimensional Pain Inventory in the SCI population) and to test its internal consistency and construct validity in a Spanish population. Guttmann Institute, Barcelona, Spain. The MPI-SCI-S along with Spanish measures of pain intensity (Numerical Rating Scale), pain interference (Brief Pain Inventory), functional independence (Functional Independence Measure), depression (Beck Depression Inventory), locus of control (Multidimensional health Locus of Control), support (Functional Social Support Questionnaire (Duke-UNC)), psychological well-being (Psychological Global Well-Being Index) and demographic/injury characteristics were assessed in persons with spinal cord injury (SCI) and chronic pain (n=126). Confirmatory factor analysis suggested an adequate factor structure for the MPI-SCI-S. The internal consistency of the MPI-SCI-S subscales ranged from acceptable (r=0.66, Life Control) to excellent (r=0.94, Life Interference). All MPI-SCI-S subscales showed adequate construct validity, with the exception of the Negative and Solicitous Responses subscales. The Spanish version of the MPI-SCI is adequate for evaluating chronic pain impact following SCI in a Spanish-speaking population. Future studies should include additional measures of pain-related support in the Spanish-speaking SCI population.

    Treatment satisfaction is recognized as an essential aspect in the evaluation of an intervention's effectiveness, but there is no measure that provides for its comprehensive assessment with regard to behavioral interventions. Informed by a conceptualization generated from a literature review, we developed a measure that covers several domains of satisfaction with behavioral interventions. In this paper, we briefly review its conceptualization and describe the Multi-Dimensional Treatment Satisfaction Measure (MDTSM) subscales. Satisfaction refers to the appraisal of the treatment's process and outcome attributes. The MDTSM has 11 subscales assessing treatment process and outcome attributes: treatment components' suitability and utility, attitude toward treatment, desire for continued treatment use, therapist competence and interpersonal style, format and dose, perceived benefits of the health problem and everyday functioning, discomfort, and attribution of outcomes to treatment. The MDTSM was completed by persons (N = 213) in the intervention group in a large trial of a multi-component behavioral intervention for insomnia within 1 week following treatment completion. The MDTSM's subscales demonstrated internal consistency reliability (α: .65 - .93) and validity (correlated with self-reported adherence and perceived insomnia severity at post-test). The MDTSM subscales can be used to assess satisfaction with behavioral interventions and point to aspects of treatments that are viewed favorably or unfavorably. © 2017 Wiley Periodicals, Inc.

    Full Text Available The goals of this research were to evaluate the Bosnian-Croatian-Serbian (BCS translation of the BIDR-6 scale, develop its short form, and to present its initial convergent/discriminative validation. The sample included 827 participants. MIRT CFA analysis revealed that fourfactor model (containing 32/40 items fits the data best, with Self-Deceptive Enhancement (SDE and Impression Management (IM both splitting into the denial (SD-D and IM-D and enhancement (SD-E and IM-E factors. Fit and item properties were generally mediocre. SD-D and IM-E subscales were the strongest sources of misfit, thus SD-E and IM-D subscales were retained in the short form, which had good fit and replicated almost all main patterns of associations with other variables of interest (e.g., HEXACO personality traits typically reported for the full SDE and IM scales in other research. Thus, 17-item BIDR-6 short form, containing only SD-E and IM-D subscales, is recommended for use in the BCS speaking area.

    The Turkish version of the Perceived Stress Scale (T-PSS-10) measures the extent to which situations in one's life are appraised as stressful. The purpose of this study was to evaluate the measurement structure of T-PSS-10. Two-hundred and thirty-five Turkish university students (93 men and 142 women) completed the T-PSS-10, the Patient Health Questionnaire-9 (PHQ-9), the General Anxiety Disorder 7-Item Scale (GAD-7), and the Inventory of Common Problems (ICP). Confirmatory factor analysis results indicated that a one-factor model did not fit the data, whereas a two-factor correlated model (stress related self-efficacy beliefs, stress related feelings of helplessness) provided a better fit between the model and the data. Significant moderate correlations were found for the stress-related self-efficacy beliefs and stress-related feelings of helplessness factors with depression, anxiety, academic difficulty, relationship problems and health problems. The internal consistency reliability coefficients for the stress-related self-efficacy beliefs and stress-related feelings of helplessness factors were 0.68 and 0.85, respectively. This study provided support for the reliability and validity of T-PSS-10 suggesting that it can be used as a screening instrument by health professionals working with Turkish college students.

    Musical training positively influences the cortical plasticity of the brain and has proven to be effective in treating chronic tinnitus. A neuro-music therapy concept, the "Heidelberg Neuro-Music Therapy" treatment was developed and evaluated. A prospective, cross-sectional design was used. N = 135 patients (mean age 47 years) with chronic, tonal tinnitus attended a standardized protocol for Neuro-Music Therapy (either "standard therapy" ST or "compact therapy" CT). The results were compared to a cognitive behavioral placebo music therapy procedure (PT). Tinnitus distress was assessed using the German version of the Tinnitus-Questionnaire (TQ) at admission, at discharge and six months after therapy. Changes were assessed statistically and by means of clinical significance. TQ scores significantly improved - independent of group allocation. But more than 80% of the music therapy patients (both ST and CT) revealed a reliable improvement ("responder") compared to 44% in the PT group. Therapy impact seems to be lasting since TQ scores remained stable until follow-up at six months. The "Heidelberg Neuro-Music Therapy" is a method with fast onset and long lasting effect for patients with "tonal" tinnitus. A number of potential working factors accounting for the treatment success are highlighted.

    Full Text Available Background: Kushta is an important solid dosage form of Unani system of medicine used to treat various ailments. Very small particle size of kushta is responsible for its rapid absorption in body leading to instant therapeutic actions. Kushta tutia (KT is one such renowned formulation used by hakims for successful management of various disorders. However, there is lack of scientific work on KT. Objectives: The present study was performed to evaluate KT physicochemically by testifying it on classical tests along with modern scientific techniques. Materials and Methods: Tutia was first detoxified as per classical literature. It was triturated with water and dried, afterwards subjected to calcination in furnace rather than cow dung cakes due to isolation of material being heated and better temperature control. Finished product was evaluated for physicochemical characteristics including preliminary tests mentioned in classical literature. Results: Floating and finger test were positive. Curd test showed no discoloration after 48 h. These findings indicate correct preparation of KT according to classical literature. Bulk density (0.96 ± 0.00 g/ml; tapped density (1.53 ± 0.00 g/ml; Hausner ratio (0.62 ± 0.00, compressibility index (37.52 ± 0.19%; loss of weight on drying (0.08 ± 0.00%; pH of 1 and 10% (5.20 ± 0.00 and 5.62 ± 0.00, respectively; total ash, acid insoluble ash, and water soluble ash values 95.75 ± 0.09, 6.57 ± 0.02, and 45.02 ± 0.20%, respectively; and extractive values 0.85 ± 0.02% were reported in KT. Conclusion: Since this work has not been reported earlier, the results obtained could be considered as the standard for KT for future studies.

    Women diagnosed with early stage (I or II) breast cancer face a highly challenging decision - whether or not to undergo adjuvant chemotherapy. We developed a decision quality instrument for chemotherapy for early stage breast cancer and sought to evaluate its performance. Cross-sectional, mailed survey of recent breast cancer survivors, providers, and healthy controls and a retest survey of survivors. The decision quality instrument includes questions on knowledge and personal goals. It results in a knowledge score and concordance score, which reflects the percentage of patients who received treatments that match their goals. Hypotheses related to acceptability, feasibility, validity, and reliability of the survey instrument were examined. Responses were received from 352 patients, 89 providers and 35 healthy controls. The decision quality instrument was feasible to implement with few missing data. The knowledge scores had good retest reliability (intraclass correlation coefficient (ICC) =0.75). Knowledge scores discriminated between providers and patients (mean difference 31.1%, 95% CI 26.9, 35.3) and between patients and healthy controls (mean difference 11.2, 95% CI 5.4, 17.1). Most providers reported that the knowledge items covered essential content. Two of the five goal items had a ceiling effect, and one goal had low content validity. The goal items had moderate retest reliability (ICC's 0.57 to 0.78). In the multivariable model of treatment, none of the patient goals was associated with receipt of chemotherapy. Age and hormone receptor status were the only variables independently associated with chemotherapy. Most patients (77.6%) had treatment concordant with that predicted by the model. Patients who had concordant treatment had similar levels of confidence and regret as those who did not. The Decision Quality Instrument is a reliable and valid measure of patient knowledge about chemotherapy, but its ability to measure concordance with patient goals is

    Psychometrically sound measures of e-cigarette dependence are lacking. We modified the PROMIS Nicotine Dependence Item Banks for use with e-cigarettes and evaluated the psychometrics of the 22-, 8- and 4-item adapted versions. 1009 adults who reported using e-cigarettes at least weekly completed an anonymous survey in Summer 2016 (50.2% male, 77.1% White, mean age 35.81 [10.71], 66.4% daily e-cigarette users, 72.6% current cigarette smokers). Psychometric analyses included confirmatory factor analysis, internal consistency, measurement invariance, examination of mean-level differences, convergent validity, and test-criterion relationships with e-cigarette use outcomes. All PROMIS-E versions had confirmable, internally consistent latent structures that were scalar invariant by sex, race, e-cigarette use (non-daily/daily), e-liquid nicotine content (no/yes), and current cigarette smoking status (no/yes). Daily e-cigarette users, nicotine e-liquid users, and cigarette smokers reported being more dependent on e-cigarettes than their counterparts. All PROMIS-E versions correlated strongly with one another, evidenced convergent validity with the Penn State E-cigarette Dependence Index and time to first e-cigarette use in the morning, and evidenced test-criterion relationships with vaping frequency, e-liquid nicotine concentration, and e-cigarette quit attempts. Similar results were observed when analyses were conducted within subsamples of exclusive e-cigarette users and duals-users of cigarettes and e-cigarettes. Each PROMIS-E version evidenced strong psychometric properties for assessing e-cigarette dependence in adults who either use e-cigarette exclusively or who are dual-users of cigarettes and e-cigarettes. However, results indicated little benefit of the longer versions over the 4-item PROMIS-E, which provides an efficient assessment of e-cigarette dependence. The availability of the novel, psychometrically sound PROMIS-E can further research on a wide range of

    Impairments in attention are commonly seen in individuals with traumatic brain injury (TBI). While visual attention assessment measurements have been rigorously developed and frequently used in cognitive neurorehabilitation, there is a paucity of auditory attention assessment measurements for patients with TBI. The purpose of this study was to field test a researcher-developed Music-based Attention Assessment (MAA), a melodic contour identification test designed to assess three different types of attention (i.e., sustained attention, selective attention, and divided attention), for patients with TBI. Additionally, this study aimed to evaluate the readability and comprehensibility of the test items and to examine the preliminary psychometric properties of the scale and test items. Fifteen patients diagnosed with TBI completed 3 different series of tasks in which they were required to identify melodic contours. The resulting data showed that (a) test items in each of the 3 subtests were found to have an easy to moderate level of item difficulty and an acceptable to high level of item discrimination, and (b) the musical characteristics (i.e., contour, congruence, and pitch interference) were found to be associated with the level of item difficulty, and (c) the internal consistency of the MAA as computed by Cronbach's alpha was .95. Subsequent studies using a larger sample of typical participants, along with individuals with TBI, are needed to confirm construct validity and internal consistency of the MAA. In addition, the authors recommend examination of criterion validity of the MAA as correlated with current neuropsychological attention assessment measurements.

    The quality standards of the Dutch Society of Intensive Care require monitoring of the satisfaction of patient's relatives with respect to care. Currently, no suitable instrument is available in the Netherlands to measure this. This study describes the development and psychometric evaluation of the questionnaire-based Consumer Quality Index 'Relatives in Intensive Care Unit' (CQI 'R-ICU'). The CQI 'R-ICU' measures the perceived quality of care from the perspective of patients' relatives, and identifies aspects of care that need improvement. The CQI 'R-ICU' was developed using a mixed method design. Items were based on quality of care aspects from earlier studies and from focus group interviews with patients' relatives. The time period for the data collection of the psychometric evaluation was from October 2011 until July 2012. Relatives of adult intensive care patients in one university hospital and five general hospitals in the Netherlands were approached to participate. Psychometric evaluation included item analysis, inter-item analysis, and factor analysis. Twelve aspects were noted as being indicators of quality of care, and were subsequently selected for the questionnaire's vocabulary. The response rate of patients' relatives was 81% (n = 455). Quality of care was represented by two clusters, each showing a high reliability: 'Communication' (α = .80) and 'Participation' (α = .84). Relatives ranked the following aspects for quality of care as most important: no conflicting information, information from doctors and nurses is comprehensive, and health professionals take patients' relatives seriously. The least important care aspects were: need for contact with peers, nuisance, and contact with a spiritual counsellor. Aspects that needed the most urgent improvement (highest quality improvement scores) were: information about how relatives can contribute to the care of the patient, information about the use of meal-facilities in the hospital, and

    This report presents a preliminary evaluation of removing used nuclear fuel (UNF) from 12 shutdown nuclear power plant sites. At these shutdown sites the nuclear power reactors have been permanently shut down and the sites have been decommissioned or are undergoing decommissioning. The shutdown sites are Maine Yankee, Yankee Rowe, Connecticut Yankee, Humboldt Bay, Big Rock Point, Rancho Seco, Trojan, La Crosse, Zion, Crystal River, Kewaunee, and San Onofre. The evaluation was divided into four components: characterization of the UNF and greater-than-Class C low-level radioactive waste (GTCC waste) inventory; a description of the on-site infrastructure and conditions relevant to transportation of UNF and GTCC waste; an evaluation of the near-site transportation infrastructure and experience relevant to shipping transportation casks containing UNF and GTCC waste, including identification of gaps in information; and, an evaluation of the actions necessary to prepare for and remove UNF and GTCC waste. The primary sources for the inventory of UNF and GTCC waste are the U.S. Department of Energy (DOE) RW-859 used nuclear fuel inventory database, industry sources such as StoreFUEL and SpentFUEL, and government sources such as the U.S. Nuclear Regulatory Commission. The primary sources for information on the conditions of site and near-site transportation infrastructure and experience included observations and information collected during visits to the Maine Yankee, Yankee Rowe, Connecticut Yankee, Humboldt Bay, Big Rock Point, Rancho Seco, Trojan, La Crosse, and Zion sites; information provided by managers at the shutdown sites; Facility Interface Data Sheets compiled for DOE in 2005; Services Planning Documents prepared for DOE in 1993 and 1994; industry publications such as Radwaste Solutions; and Google Earth. State and Regional Group representatives, a Tribal representative, and a Federal Railroad Administration representative participated in six of the shutdown site

    A preliminary evaluation of removing spent nuclear fuel (SNF) from 13 shutdown nuclear power plant sites was performed. At these shutdown sites the nuclear power reactors have been permanently shut down and the sites have been decommissioned or are undergoing decommissioning. The shutdown sites were Maine Yankee, Yankee Rowe, Connecticut Yankee, Humboldt Bay, Big Rock Point, Rancho Seco, Trojan, La Crosse, Zion, Crystal River, Kewaunee, San Onofre, and Vermont Yankee. The evaluation was divided into four components: Characterization of the SNF and greater-than-Class C low-level radioactive waste (GTCC waste) inventory A description of the on-site infrastructure at the shutdown sites An evaluation of the near-site transportation infrastructure and transportation experience at the shutdown sites An evaluation of the actions necessary to prepare for and remove SNF and GTCC waste. The primary sources for the inventory of SNF and GTCC waste were the U.S. Department of Energy (DOE) spent nuclear fuel inventory database, industry publications such as StoreFUEL, and government sources such as the U.S. Nuclear Regulatory Commission. The primary sources for information on the conditions of on-site infrastructure and near-site transportation infrastructure and experience included information collected during site visits, information provided by managers at the shutdown sites, Facility Interface Data Sheets compiled for DOE in 2005, Services Planning Documents prepared for DOE in 1993 and 1994, industry publications such as Radwaste Solutions, and Google Earth. State staff, State Regional Group representatives, a Tribal representative, and a Federal Railroad Administration representative have participated in nine of the shutdown site visits. Every shutdown site was found to have at least one off-site transportation mode option for removing its SNF and GTCC waste; some have multiple options. Experience removing large components during reactor decommissioning provided an

    Intuitive eating is an adaptive dietary behavior that emphasizes eating in response to physiological hunger and satiety cues. The Intuitive Eating Scale-2 (IES-2) measures such attitudes and behaviors. The aim of the present study was to adapt the IES-2 to the French context and to test its psychometric properties in 335 women and 297 men participating in the NutriNet-Santé study. We evaluated the construct validity of the IES-2 by testing hypotheses with regard to its factor structure, relationships with scores of the revised 21-item Three Factor Eating Questionnaire and the Center for Epidemiologic Studies Depression scale, and differences between "a priori" relevant subgroups. First, the exploratory factor analysis revealed three main dimensions: Eating for Physical Rather than Emotional Reasons, Reliance on Hunger and Satiety Cues, and Unconditional Permission to Eat. Second-order confirmatory factor analysis upheld the 3-factor solution influenced by a broader intuitive eating dimension. IES-2 total score was negatively related to cognitive restraint (r = -0.31, P < 0.0001), emotional eating (r = -0.58, P < 0.0001), uncontrolled eating (r = -0.40, P < 0.0001), and depressive symptoms (r = -0.20, P < 0.0001). IES-2 subscales showed similar correlations. Women had lower scores than did men for the IES-2 total scale (3.3 in women vs. 3.5 in men, P < 0.0001), Eating for Physical Reasons, and Unconditional Permission to Eat subscales. Current or former dieters had lower scores on the IES-2 total scale and on all subscales than did those who had never dieted (all P < 0.01). Finally, results showed satisfactory reliability for the IES-2 total scores (internal consistency = 0.85 and test-retest reliability = 0.79 over a mean 8-week period) and for its subscales. Thus, the French IES-2 can be considered a useful instrument for assessing adult intuitive eating behaviors in empirical and epidemiological studies in the

    The 12-item short-form health survey (SF-12) was developed as a shorter alternative to the SF-36 for use in large-scale studies as an applicable instrument for measuring health-related quality of life. The main purpose of this study was to evaluate the psychometric properties of the Tunisian version of the SF-12. A stratified representative sample (N = 3,582) of the general Tunisian population aged 18 years and over was interviewed. SF-12 summary scores were derived using the standard US algorithm. Factor analysis was used to confirm the hypothesized component structure of the SF-12 items. Reliability was estimated using internal consistency, and construct validity was investigated with "known groups" validity testing and via convergent and divergent validity. SF-12 summary scores distinguished well, and in the expected manner, between groups of respondents on the basis of gender, age, education and socioeconomic status, thus providing evidence of construct validity. Mean scores in the total sample were 50.11 (SD 8.53) for the physical component summary (PCS) score and 47.96 (SD 9.82) for the mental component summary (MCS) score. The results showed satisfactory internal consistency and acceptable convergent validity for both summary scores. Cronbach's α coefficient for PCS-12 and MCS-12 was 0.73 and 0.72, respectively. Known groups comparison showed that the SF-12 discriminated well between groups of respondents on the basis of gender, age, education and socioeconomic status. In addition, no floor or ceiling effects at baseline were observed. The PCA confirmed the two-factor structure of the SF-12 items. Items belonging to the physical component correlated more strongly with the PCS-12 than those with the MCS-12. Similarly, items belonging to the mental component correlated more strongly with the MCS-12 than those with the PCS-12. The findings suggest that the SF-12 appears to be a valid and reliable measure that can be used for measuring of population health

    Full Text Available The purpose of this study was to research the psychometrical parameters and the clinical-dynamic features of patients with schizophrenia in depending on their constitutionally-morphological type.Material and methods. The examination of 86 patients with schizophrenia who are hospitalized at Department of endogenous mental disorders of Mental Health Research Institute was conducted. The study included patients of age from 18 to 65 years old with prescription of catamnesis at least 1 year and whose state at the time of examination corresponded to the diagnostic criteria for schizophrenia from the ICD-10 (International Classification of Diseases 10th Revision. The examination included filling in a modified version of Basic Card of Standardized Description of the Patient with Schizophrenia and his Relative, Positive and Negative Syndrome Scale (PANSS, Clinical Global Impression Scale (CGI. In addition to that patients were examined using anthropometrical method by V.V. Bunak. Statistical significance of differences in the data was evaluated using the Kruskal – Wallis test by ranks, the Mann – Whitney U-test, and Pearson’s chi-squared test. The correlation analysis was performed by the Spearman’s rank correlation test. The K-Means Cluster Analysis was used to determine of the qualitative interrelation and conjugation between the clinical characteristics of the examined.The results of the study revealed that many parameters of the functioning in these patient groups have statistically significant differences. Use of the K-Means Cluster Analysis was allowed to reveal the internal structure of the data, to group the individual observations according to their degree of similarity.Conclusions. The obtained data leads to the assumption that the constitutionally-morphological type of patients has an impact on the clinical course of schizophrenia, as well as their adaptation abilities. Asthenic constitutionally-morphological type is a factor of

    In recent years, there has been increased interest in measuring the climate for infection prevention; however, reliable and valid instruments are lacking. This study tested the psychometric properties of the Leading a Culture of Quality for Infection Prevention (LCQ-IP) instrument measuring the infection prevention climate in a sample of 972 infection preventionists from acute care hospitals. An exploratory principal component analysis showed that the instrument had structural validity and captured 4 factors related to the climate for infection prevention: Psychological Safety, Prioritization of Quality, Supportive Work Environment, and Improvement Orientation. LCQ-IP exhibited excellent internal consistency, with a Cronbach α of .926. Criterion validity was supported with overall LCQ-IP scores, increasing with the number of evidence-based prevention policies in place (P = .047). This psychometrically sound instrument may be helpful to researchers and providers in assessing climate for quality related to infection prevention. © The Author(s) 2015.

    Body functionality has been identified as an important dimension of body image that has the potential to be useful in the prevention and treatment of negative body image and in the enhancement of positive body image. Specifically, cultivating appreciation of body functionality may offset appearance concerns. However, a scale assessing this construct has yet to be developed. Therefore, we developed the Functionality Appreciation Scale (FAS) and examined its psychometric properties among three online community samples totalling 1042 women and men (ns=490 and 552, respectively). Exploratory factor analyses revealed a unidimensional structure with seven items. Confirmatory factor analysis upheld its unidimensionality and invariance across gender. The internal consistency, test-retest reliability, criterion-related, and construct (convergent, discriminant, incremental) validity of its scores were upheld. The FAS is a psychometrically sound measure that is unique from existing positive body image measures. Scholars will find the FAS applicable within research and clinical settings.

    To explore the relationship between scores on the Test Your Memory (TYM) battery and findings from a more exhaustive neurocognitive assessment. The TYM and fourteen psychometric tests were administered to 84 subjects aged 50 or older who attended an outpatient neurology clinic due to cognitive symptoms. Each patient's cognitive state was determined independently from his/her score on the TYM (CDR 0, n=25; CDR 0.5, n=45; CDR 1, n=14). We analysed concurrent validity of TYM scores and results from the psychometric tests, as well as the degree of concordance between the two types of measurement, by contrasting normalised data from each instrument. Although the intraclass correlation coefficient was 0.67 (confidence interval 95%, 0.53-0.77), analysis of the Bland-Altman plot and the curve on the survival-agreement plot (Luiz et al. method) demonstrates that the individual distances between the two methods exhibit excessive dispersion from a clinical viewpoint. TYM-based predictions of the mean z-score on psychometric tests differed substantially from real results in 30% of the subjects. Concordance of 95% can only be achieved by accepting absolute inter-instrument differences of up to 0.87 as identical values. Furthermore, the TYM underestimates cognitive performance for low values and overestimates it for high values. The TYM is a cognitive screening test which should not be used to predict results on psychometric tests or to detect cognitive changes in clinical trials.

    Emotion regulation is thought to play an important role in adaptation to cancer. However, the emotion regulation questionnaire (ERQ), a widely used instrument to assess emotion regulation, has not yet been validated in this context. This study addresses this gap by examining the psychometric properties of the ERQ in a sample of Portuguese women with cancer. The ERQ was administered to 204 women with cancer (mean age = 48.89 years, SD = 7.55). Confirmatory factor analysis and item response theory analysis were used to examine psychometric properties of the ERQ. Confirmatory factor analysis confirmed the 2-factor solution proposed by the original authors (expressive suppression and cognitive reappraisal). This solution was invariant across age and type of cancer. Item response theory analyses showed that all items were moderately to highly discriminant and that items are better suited for identifying moderate levels of expressive suppression and cognitive reappraisal. Support was found for the internal consistency and test-retest reliability of the ERQ. The pattern of relationships with emotional control, alexithymia, emotional self-efficacy, attachment, and quality of life provided evidence of the convergent and concurrent validity for both dimensions of the ERQ. Overall, the ERQ is a psychometrically sound approach for assessing emotion regulation strategies in the oncological context. Clinical implications are discussed.

    Full Text Available Background: Designing a valid and reliable questionnaire that allows a fair evaluation of sexual knowledge and attitudes and develop a proper sexual educational program is necessary. Objective: The present study was designed to develop and psychometric evaluation of the sexual knowledge and attitudes scale for premarital couples. Materials and Methods: An exploratory mixed method study was conducted in two phases; in the first, in order to develop a questionnaire an item pool was generated on sexual knowledge and attitudes through focus group discussions and individual interviews. In the second phase, the psychometric properties of the questionnaire were examined. For this purpose, face validity, content validity as well as construct validity were conducted. Reliability was assessed by the Cronbach’s alpha coefficient to assess internal consistency and test-retest reliability. Results: In the first phase an item pool with 88 questions was generated (sexual knowledge 45 items and sexual attitudes 43 items. In the second phase, the number of final items reduced to 33 and 34 items of sexual knowledge and sexual attitudes respectively, through exploratory factor analysis (EFA. Five factors for sexual knowledge and six factors for sexual attitudes identified by EFA. The Cronbach’s alpha coefficient for two sections was 0.84 and 0.81 respectively. The test- retest correlations for sexual knowledge and sexual attitude was 0.74 and 0.82 respectively. Conclusion: The findings suggest that the Sexual Knowledge and Attitudes Scale for Premarital Couples is a valid and reliable instrument. Further studies are needed to establish stronger psychometric properties for the questionnaire.

    The development of clinical reasoning skills in recognising and responding to clinical deterioration is essential in pre-registration nursing education. Simulation has been increasingly used by educators to develop this skill. To develop and evaluate the psychometric properties of a Clinical Reasoning Evaluation Simulation Tool (CREST) for measuring clinical reasoning skills in recognising and responding to clinical deterioration in a simulated environment. A scale development with psychometric testing and mixed methods study. Nursing students and academic staff were recruited at a university. A three-phase prospective study was conducted. Phase 1 involved the development and content validation of the CREST; Phase 2 included the psychometric testing of the tool with 15 second-year and 15 third-year nursing students who undertook the simulation-based assessment; Phase 3 involved the usability testing of the tool with nine academic staff through a survey questionnaire and focus group discussion. A 10-item CREST was developed based on a model of clinical reasoning. A content validity of 0.93 was obtained from the validation of 15 international experts. The construct validity was supported as the third-year students demonstrated significantly higher (preasoning scores than the second-year students. The concurrent validity was also supported with significant positive correlations between global rating scores and almost all subscale scores, and the total scores. The predictive validity was supported with an existing tool. The internal consistency was high with a Cronbach's alpha of 0.92. A high inter-rater reliability was demonstrated with an intraclass correlation coefficient of 0.88. The usability of the tool was rated positively by the nurse educators but the need to ease the scoring process was highlighted. A valid and reliable tool was developed to measure the effectiveness of simulation in developing clinical reasoning skills for recognising and responding to

    Older adults with chronic disease are more vulnerable to abuse. Early and accurate detection of the elderly abuse phenomenon can help identify health-promoting solutions for the elderly, their family, and society. The purpose of this study was to design and evaluate the psychometric properties of a questionnaire on elderly abuse by family caregivers among older adults on hemodialysis. Qualitative and quantitative research methodologies were used to develop the questionnaire. The item pool was compiled from literature reviews and the Delphi method. The literature reviews comprised 22 studies. The psychometric properties of the questionnaire were verified using face, content, and construct validity, and the reliability was tested using Cronbach's alpha reliability. A 57-item questionnaire was developed after the psychometric evaluation. The Kaiser-Meyer-Olkin index and Bartlett's test of sphericity showed reliable results. Seven components from the exploratory content analysis including psychological misbehavior, authority deprivation, physical misbehavior, financial misbehavior, being abandoned, caring neglect, and emotional misbehavior explained 74.769% of the total variance. Cronbach's alpha was 0.98 and the interclass correlation coefficient was r =0.91 responding to the items twice ( p <0.001), which shows a high level of tool stability. This study developed a questionnaire to assess elderly abuse by family caregivers among older adults on hemodialysis. It is recommended as a mini scale that can be used both in statistical and practical studies, and that is valid and reliable. Nurses or other health care providers can use it in health centers, dialysis centers, or at the house of the patient.

    The European Organisation of Research and Treatment of Cancer (EORTC) Quality of Life Group is developing computerized adaptive testing (CAT) versions of all EORTC Quality of Life Questionnaire (QLQ-C30) scales with the aim to enhance measurement precision. Here we present the results on the field-testing and psychometric evaluation of the item bank for cognitive functioning (CF). In previous phases (I-III), 44 candidate items were developed measuring CF in cancer patients. In phase IV, these items were psychometrically evaluated in a large sample of international cancer patients. This evaluation included an assessment of dimensionality, fit to the item response theory (IRT) model, differential item functioning (DIF), and measurement properties. A total of 1030 cancer patients completed the 44 candidate items on CF. Of these, 34 items could be included in a unidimensional IRT model, showing an acceptable fit. Although several items showed DIF, these had a negligible impact on CF estimation. Measurement precision of the item bank was much higher than the two original QLQ-C30 CF items alone, across the whole continuum. Moreover, CAT measurement may on average reduce study sample sizes with about 35-40% compared to the original QLQ-C30 CF scale, without loss of power. A CF item bank for CAT measurement consisting of 34 items was established, applicable to various cancer patients across countries. This CAT measurement system will facilitate precise and efficient assessment of HRQOL of cancer patients, without loss of comparability of results.

    A pediatric chronic health condition not only influences a child's life, but also has impacts on parent health-related quality of life (HRQOL) and family functioning. To provide care and social support to these families, a psychometrically well-developed instrument for measuring these impacts is of great importance. The present study is aimed to evaluate the psychometric properties of the Chinese version of the PedsQL™ Family Impact Module. The cross-cultural adaptation of the PedsQL™ Family Impact Module was performed following the PedsQL™ Measurement Model Translation Methodology. The Chinese version of the PedsQL™ Family Impact Module was administered to 136 parents of children with asthma and 264 parents of children with heart disease from four Triple A hospitals. The psychometric properties such as feasibility, internal consistency reliability, item-subscale correlations and construct validity were evaluated. The percentage of missing item responses was less than 0.1% for both asthma and heart disease sample groups. The Chinese version of the PedsQL™ Family Impact Module showed ceiling effects but had acceptable reliability (Cronbach's Alpha Coefficients were higher than 0.7 in all the subscales except "Daily Activities" in the asthma sample group). There were higher correlation coefficients between items and their hypothesized subscales than those with other subscales. The asthma sample group reported higher parent HRQOL and family functioning than the heart disease sample group. In the heart disease sample group, parents of outpatients reported higher parent HRQOL and family functioning than parents of inpatients. Confirmatory factor analysis showed that the instrument had marginally acceptable construct validity with some Goodness-of-Fit indices not reaching the standard indicating acceptable model fit. The Chinese version of the PedsQL™ Family Impact Module has adequate psychometric properties and could be used to assess the impacts of

People with OCD are more likely to report impaired social and occupational functioning. Although effective treatments of the OCD exist, many sufferers from this disorder are continuously misdiagnosed. Therefore, improving the assessment of the OCD remains an important area of scientific research. The main goal of the study is the initial verification of psychometric properties in the Polish version of the Obsessive-Compulsive Inventory-Revised (OCI-R in a college student sample. Material and Methods: A group of students completed a battery of measures consisting of obsessive-compulsive symptoms (The OCI-R, The Yale-Brown Obsessive Compulsive Scale, depression (The Beck Depression Inventory and anxiety trait (The State-Trait Anxiety Inventory. Results: A confirmatory factor analysis, conducted on data from 334 university students, supported a solid and replicable 6-fold factor structure of the OCI-R. Further analyses on test-retest reliability (following a 1-month interval, convergent and divergent validity of the OCI-R were respectively conducted in a group of 137 students who had completed a battery of measures mentioned above. The results showed adequate testretest reliability for the full scale and subscales cores, high internal consistency and confirmed satisfactory convergent and divergent validity. Conclusions: The study constitutes the first phase of work on a Polish version of measurement for obsessive-compulsive symptoms. Satisfactory results obtained in a non-clinical sample allow to recognize this method to be promising for further research. Int J Occup Med Environ Health 2016;29(6:1011–1021

    School bullying is a growing problem. The current study is aimed at culturally adapting and assessing the psychometric properties of a brief scale to measure bullying. A cross-cultural adaptation of the brief scale -Adolescent Peer Relations Instrument-Bullying (APRI)- was performed using the translation and back-translation technique. The Spanish version of APRI questionnaire was administered to a sample of 1,428 schoolchildren aged 12-14years in the region of Mar Menor in Murcia (Spain). Exploratory factor analysis, with oblique rotation, was used to assess the validity of the internal structure, the Cronbach's alpha to analyse their consistency, and the Kruskal-Wallis test to check their ability to discriminate between subjects with varying degrees of bullying according to Kidscreen-52 scale of social acceptability RESULTS: Two factors were identified in the adapted version of APRI (physical victimisation and verbal/social victimisation), similar to those in the original scale. The questionnaire has high internal consistency (Cronbach's alpha=0.94) and discrimination capacity (P<01), with significant effect sizes between degrees of bullying. The internal structure of the APRI Spanish version is similar to the original, and its scores confirm high reliability and construct validity. Further studies need to be performed with broader age ranges and confirmatory analysis techniques, to ratify the equivalence of the adapted version with the original version.

    Defining 'effectiveness' in the context of community mental health teams (CMHTs) has become increasingly difficult under the current pattern of provision required in National Health Service mental health services in England. The aim of this study was to establish the characteristics of multi-professional team working effectiveness in adult CMHTs to develop a new measure of CMHT effectiveness. The study was conducted between May and November 2010 and comprised two stages. Stage 1 used a formative evaluative approach based on the Productivity Measurement and Enhancement System to develop the scale with multiple stakeholder groups over a series of qualitative workshops held in various locations across England. Stage 2 analysed responses from a cross-sectional survey of 1500 members in 135 CMHTs from 11 Mental Health Trusts in England to determine the scale's psychometric properties. Based on an analysis of its structural validity and reliability, the resultant 20-item scale demonstrated good psychometric properties and captured one overall latent factor of CMHT effectiveness comprising seven dimensions: improved service user well-being, creative problem-solving, continuous care, inter-team working, respect between professionals, engagement with carers and therapeutic relationships with service users. The scale will be of significant value to CMHTs and healthcare commissioners both nationally and internationally for monitoring, evaluating and improving team functioning in practice. © 2015 John Wiley & Sons Ltd.

    The Self-Assessment of Psoriasis Symptoms - Clinical Trials (SAPS-CT) and SAPS - Real World (SAPS-RW) were simultaneously created to assess the experience of plaque psoriasis in two unique contexts. Qualitative and quantitative research was conducted in four phases namely concept elicitation, questionnaire construction, content evaluation and psychometric evaluation. Following concept elicitation, 18 concepts were selected to inform questionnaire construction of the SAPS-CT and SAPS-RW. To accommodate each context of use, the SAPS-CT asks respondents to rate the target symptom 'at its worst' in the 24 h prior to assessment, while the SAPS-RW asks respondents to rate the target symptom "on average" in the 7 days prior to assessment. Cognitive debriefing confirmed that patients could comprehend and provide meaningful responses to both versions and, after minor modifications, resulted in 11-item questionnaires administered in an observational study (N = 200). Results from the observational study informed further item reduction (SAPS-RW to six items and SAPS-CT to nine items) and demonstrated that scores from each were reliable (Cronbach's α > 0.90, test-retest intraclass correlation coefficient >0.70), construct valid and able to differentiate among clinically distinct groups. The SAPS-CT and SAPS-RW are content-valid PRO questionnaires capable of producing psychometrically sound scores when administered chronic to plaque psoriasis patients.

    The Western Ontario Meniscal Evaluation Tool (WOMET) is a questionnaire designed to evaluate the health-related quality of life (HRQOL) of patients with meniscal pathology. Our study aims to culturally adapt and validate the WOMET into a Chinese version. We translated the WOMET into Chinese. Then, a total of 121 patients with meniscal pathology were invited to participate in this study. To assess the test-retest reliability, the Chinese version WOMET was completed twice at 7-day intervals by the participants. The construct validity was assessed using Pearson's correlation coefficient or Spearman's correlation to test for correlations among the Chinese version WOMET and the eight domains of Short Form-36 (SF-36), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the International Knee Documentation Committee (IKDC) score. Responsiveness was tested by comparison of the preoperative and postoperative scores of the Chinese version WOMET. The test-retest reliability of the overall scale and different domains were all found to be excellent. The Cronbach's α was 0.90. The Chinese version WOMET correlated well with other questionnaires which suggested good construct validity. We observed no ceiling and floor effects of the Chinese version WOMET. We also found good responsiveness for the effect size, and the standardized response mean values were 0.86 and 1.11. The Chinese version of the WOMET appears to be reliable and valid in evaluating patients with meniscal pathology.

    The applicability and validity of many patient-reported outcome measures in the high-functioning population are not well understood. To compare the psychometric properties of the modified Harris Hip Score (mHHS), the Hip Outcome Score activities of daily living subscale (HOS-ADL) and sports (HOS-sports), and the Lower Extremity Computerized Adaptive Test (LE CAT). The hypotheses was that all instruments would perform well but that the LE CAT would show superiority psychometrically because a combination of CAT and a large item bank allows for a high degree of measurement precision. Cohort study (diagnosis); Level of evidence, 2. Data were collected from 472 advanced-age, active participants from the Huntsman World Senior Games in 2012. Validity evidences were examined through item fit, dimensionality, monotonicity, local independence, differential item functioning, person raw score to measure correlation, and instrument coverage (ie, ceiling and floor effects), and reliability evidences were examined through Cronbach alpha and person separation index. All instruments demonstrated good item fit, unidimensionality, monotonicity, local independence, and person raw score to measure correlations. The HOS-ADL had high ceiling effects of 36.02%, and the mHHS had ceiling effects of 27.54%. The LE CAT had ceiling effects of 8.47%, and the HOS-sports had no ceiling effects. None of the instruments had any floor effects. The mHHS had a very low Cronbach alpha of 0.41 and an extremely low person separation index of 0.08. Reliabilities for the LE CAT were excellent and for the HOS-ADL and HOS-sports were good. The LE CAT showed better psychometric properties overall than the HOS-ADL, HOS-sports, and mHHS for the senior population. The mHHS demonstrated pronounced ceiling effects and poor reliabilities that should be of concern. The high ceiling effects for the HOS-ADL were also of concern. The LE CAT was superior in all psychometric aspects examined in this study. Future

    Internet Gaming Disorder (IGD) is in the early stages of recognition as a disorder, following its inclusion in the Diagnostic and Statistical Manual for Mental Disorders (DSM-5; American Psychiatric Association(1)) as a condition for further study. Existing measures of Internet gaming pathology are limited in their ability to measure IGD as defined in the DSM-5. We present the initial development and validation of a new measure derived from the proposed DSM-5 criteria for IGD, the Personal Internet Gaming Disorder Evaluation-9 (PIE-9). A student sample (n = 119) and a community sample (n = 285), sourced through a variety of online gaming forums, completed an online survey comprising the new measure, existing measures of IGD, and a range of health and demographic questions. Exploratory and confirmatory factor analysis supported a single factor structure for the 9-item PIE-9. Internal consistency (α = 0.89) and test-retest reliability (intraclass correlation [ICC] = 0.77) were high. Convergent validity was demonstrated with similar gaming addiction measures. Predictive validity was established through significant differences in distress and disability between those who met the criteria for IGD and those who did not. The distress and disability associated with meeting IGD criteria fell within the range of other common DSM-5 disorders. Preliminary testing of the PIE-9 has demonstrated that it is an efficient and straightforward measure for use in further research of IGD, and as a potential screening measure in clinical practice.

    Background The Maslach Burnout Inventory (MBI) is the mainstream measure for burnout. However, its psychometric properties have been questioned, and alternative measurement models of the inventory have been suggested. Aims Different models for the number of items and factors of the MBI-HSS, the version of the Inventory for the Human Service sector, were tested in order to identify the most appropriate model for measuring burnout in Italy. Methods The study dataset consisted of a sample of 925 nurses. Ten alternative models of burnout were compared using confirmatory factor analysis. The psychometric properties of items and reliability of the MBI-HSS subscales were evaluated. Results Item malfunctioning may confound the MBI-HSS factor structure. The analysis confirmed the factorial structure of the MBI-HSS with a three-dimensional, 20-item assessment. Conclusions The factorial structure underlying the MBI-HSS follows Maslach’s definition when items are reduced from the original 22 to a 20-item set. Alternative models, either with fewer items or with an increased number of latent dimensions in the burnout structure, do not yield better results to justify redefining the item set or theoretically revising the syndrome construct.

    Health care professionals are coming under increased pressure to empirically monitor patient outcomes across settings as a means of improving clinical practice. Within the psychiatric and primary care communities, many have begun utilizing brief psychometric measures of psychological functioning to accomplish these goals. The purpose of this study was to evaluate the psychometric properties and clinical utility of the Depression, Anxiety, and Stress Scales-21-item version (DASS-21), and contribute normative data to facilitate interpretation using a sample of U.S. adults (N = 503). Item-scale convergence was generally supported, although assumptions of item-scale divergence were not met. Only 86%, 50%, and 43% of Depression, Anxiety, and Stress items, respectively, correlated significantly greater with their hypothesized scales than other scales. Internal consistency reliability was acceptable for all scales and comparable to existing research (αs = .91, .80, and .84 for Depression, Anxiety, and Stress, respectively). Scale-level correlations were greater than what has been reported elsewhere (range of rs = .68 to .73), and principal components analysis supported the extraction of only one component accounting for 47% of the item-level variance. However, confirmatory factor analysis (CFA) favored a three-factor structure when compared to a one-factor model. The implications for the health care professions are discussed.

    The aim of the present longitudinal study was the psychometric evaluation of the Substance Use Risk Profile Scale (SURPS). We analyzed data from N = 2,022 adolescents aged 13 to 15 at baseline assessment and 2 years later (mean interval 2.11 years). Missing data at follow-up were imputed (N = 522). Psychometric properties of the SURPS were analyzed using confirmatory factor analysis. We examined structural as well as convergent validity with other personality measurements and drinking motives, and predictive validity for substance use at follow-up. The hypothesized 4-factorial structure (i.e., anxiety sensitivity, hopelessness, impulsivity [IMP], and sensation seeking [SS]) based on all 23 items resulted in acceptable fit to empirical data, acceptable internal consistencies, low to moderate test-retest reliability coefficients, as well as evidence for factorial and convergent validity. The proposed factor structure was stable for both males and females and, to lesser degree, across languages. However, only the SS and the IMP subscales of the SURPS predicted substance use outcomes at 16 years of age. The SURPS is unique in its specific assessment of traits related to substance use disorders as well as the resulting shortened administration time. Test-retest reliability was low to moderate and comparable to other personality scales. However, its relation to future substance use was limited to the SS and IMP subscales, which may be due to the relatively low-risk substance use pattern in the present sample.

    This study describes the development and psychometric evaluation of HPV Clinical Trial Survey for Parents with Children Aged 9 to 15 (CTSP-HPV) using traditional instrument development methods and community engagement principles. An expert panel and parental input informed survey content and parents recommended study design changes (e.g., flyer wording). A convenience sample of 256 parents completed the final survey measuring parental willingness to consent to HPV clinical trial (CT) participation and other factors hypothesized to influence willingness (e.g., HPV vaccine benefits). Cronbach's a, Spearman correlations, and multiple linear regression were used to estimate internal consistency, convergent and discriminant validity, and predictively validity, respectively. Internal reliability was confirmed for all scales (a ≥ 0.70.). Parental willingness was positively associated (p < 0.05) with trust in medical researchers, adolescent CT knowledge, HPV vaccine benefits, advantages of adolescent CTs (r range 0.33-0.42), supporting convergent validity. Moderate discriminant construct validity was also demonstrated. Regression results indicate reasonable predictive validity with the six scales accounting for 31% of the variance in parents' willingness. This instrument can inform interventions based on factors that influence parental willingness, which may lead to the eventual increase in trial participation. Further psychometric testing is warranted. © 2015 Wiley Periodicals, Inc.

    Objective The main objective of this work was to translate the English version of ASSET (A Shortened Stress Evaluation Tool) into the Portuguese version and to validate its psychometric properties. Additionally, this work tested the convergent validity of the instrument. Methods The translation and retroversion were conducted by experts and submitted to the authors for approval. Within an observational, cross-sectional study, regarding mental health at the workplace, ASSET together with other scales was applied to a sample of 405 participants. The psychometric validity of the subscales was studied using confirmatory factorial analysis. Results The factorial structure of ASSET is globally supported by the results, with the Perceptions of Your Job and Attitudes Towards your Organisation subscales requiring slight adjustments in the item structure and the Your Health subscales replicating the original structure. The convergent validity also supports the ASSET, showing that all subscales are significantly correlated with variables used to test convergence. Conclusions Globally, the results constitute an important contribution to ASSET and open the possibility of its usage among Portuguese-speaking countries. The results provide an evidence on the validity of the instrument and, in particular, of the mental and physical health subscales. PMID:29440211

    To estimate the psychometric properties of a culturally adapted version of the Young Children's Participation and Environment Measure (YC-PEM) for use among Singaporean families. This is a prospective cohort study. Caregivers of 151 Singaporean children with (n = 83) and without (n = 68) developmental disabilities, between 0 and 7 years, completed the YC-PEM (Singapore) questionnaire with 3 participation scales (frequency, involvement, and change desired) and 1 environment scale for three settings: home, childcare/preschool, and community. Setting-specific estimates of internal consistency, test-retest reliability, and construct validity were obtained. Internal consistency estimates varied from .59 to .92 for the participation scales and .73 to .79 for the environment scale. Test-retest reliability estimates from the YC-PEM conducted on two occasions, 2-3 weeks apart, varied from .39 to .89 for the participation scales and from .65 to .80 for the environment scale. Moderate to large differences were found in participation and perceived environmental support between children with and without a disability. YC-PEM (Singapore) scales have adequate psychometric properties except for low internal consistency for the childcare/preschool participation frequency scale and low test-retest reliability for home participation frequency scale. The YC-PEM (Singapore) may be used for population-level studies involving young children with and without developmental disabilities.

    The Shoulder Pain Disability Index (SPADI) is a recently published but widely used outcome measure. This study included 136 patients with shoulder disorders. SPADI was first translated and back-translated and then subjected to psychometric validation. Participants completed the Spanish versions of the SPADI, general health (SF-12), the Simple Shoulder Test (SST), Disability of Arm, Shoulder, and Hand (DASH) questionnaires and a pain intensity visual analog scale (VAS). The factors explained 62.8 % of the variance, with an internal consistency of α = 0.916 and 0.860, respectively. The confirmatory factor analysis showed a Comparative Fit Index of 0.82 and a Normed Fit Index of 0.80. The Root Mean Square Error of Aproximation was 0.12. The x (2) test for the 2-factor model was significant (x (2) = 185.41, df = 62, p validity analysis, strong positive correlations were observed between Spanish Version of the SPADI and DASH (pain: r = 0.80; p Spanish Version of the SPADI and VAS (pain: r = 0.67; p Spanish Version of the SPADI and SST-Sp (pain: r = -0.71; p Spanish Version of the SPADI was only weakly correlated with physical and mental components of SF-12 (both r = 0.40; p Spanish version of SPADI demonstrated satisfactory psychometric properties in a patient sample in the hospital setting.

    The 10-item version of Perceived Stress Scale (PSS-10) is a widely used tool to measure stress. The Malay version of the PSS-10 has been validated among Malaysian Medical Students. However, studies have not been conducted to assess its validity in occupational settings. The aim of this study is to assess the psychometric properties of the Malay version of the PSS-10 in two occupational setting in Malaysia. This study was conducted among 191 medical residents and 513 railway workers. An exploratory factor analysis was performed using the principal component method with varimax rotation. Correlation analyses, Kaiser-Meyer-Olkin, Bartlett's test of Sphericity and Cronbach's alpha were obtained. Statistical analysis was carried out using statistical package for the social sciences version 16 (SPSS, Chicago, IL, USA) software. Analysis yielded two factor structure of the Malay version of PSS-10 in both occupational groups. The two factors accounted for 59.2% and 64.8% of the variance in the medical residents and the railway workers respectively. Factor loadings were greater than 0.59 in both occupational groups. Cronbach's alpha co-efficient was 0.70 for medical residents and 0.71 for railway workers. The Malay version of PSS-10 had adequate psychometric properties and can be used to measure stress among occupational settings in Malaysia.

    Past studies have demonstrated that the Brief Negative Symptom Scale (BNSS) has excellent psychometric properties in patients with schizophrenia. In the current study, we extended this literature by examining psychometric properties of the BNSS in outpatients diagnosed with bipolar disorder (n=46), outpatients with schizophrenia (n=50), and healthy controls (n=27). Participants completed neuropsychological testing and a clinical interview designed to assess negative, positive, disorganized, mood, and general psychiatric symptoms. Results indicated differences among the 3 groups in the severity of all BNSS items, with SZ and BD scoring higher than CN; however, SZ and BD only differed on blunted affect and alogia items, not anhedonia, avolition, or asociality. BD patients with a history of psychosis did not differ from those without a history of psychosis on negative symptom severity. The BNSS had excellent internal consistency in SZ, BD, and CN groups. Good convergent and discriminant validity was apparent in SZ and BD groups, as indicated by relationships between the BNSS and other clinical rating scales. These findings support the validity of the BNSS in broadly defined serious mental illness populations. Copyright © 2015 Elsevier B.V. All rights reserved.

    Supercapacitors are identified since years as a new technology enabling energy storage together with high power delivery capability to the system. A recent ESA study [1] led by Astrium has demonstrated the interest of these devices for space application, providing that reliability and end of life performances are demonstrated. A realistic commercial on the shelf (COTS) approach (or with limited design modification approved by potential suppliers) has been favoured (as for batteries). This paper presents preliminary test results done by Astrium on COTS supercapacitors: accelerated life tests, calendar life tests, technology analyses. Based on these results, assessment and lessons learnt are drawn in view of future exhaustive supercapacitor validation and future qualification.

    The 12-item brief version of the Fear of Negative Evaluation Scale (BFNE) is one of the most widely used instruments to assess fear of negative evaluation. Recent evidence strongly supports the version composed of 8 straightforward items (BFNE-S), which possessesstronger psychometric properties. The purpose of the current study is to examine the psychometric prop-erties of the Chinese versions of the BFNE and BFNE-S for middle school students. A total of 1009 middle school students were recruited in this study. The BFNE, the BFNE-S, the Friedman-Bendas Text Anxiety Scale (FBTAS), and the Social Anxiety Scale (SAS) were administered to 497 participants, and 52 participants were re-tested after four weeks. The BFNE, the BFNE-S, the Rosenberg Self-Esteem Scale (RSES), and the Balanced Inventory of Desirable Responding (BIDR) wereadministered to 492 participants. The BFNE and BFNE-S significantly cor-related with all the scales, supporting their convergent, divergent and concurrent validity. The Cronbach's alpha of the BFNE (BFNE-S) was 0.864 (0.867) with 497 par-ticipants and 0.886 (0.844) with 492 participants, and the test-retest reliability coefficient was 0.791 (0.855) (ICC). Although the EFA identified a two-factor solution in which the 8 straightfor-ward items loaded on one factor and the 4 reversed items loaded on the other, the CFA, using a random intercept model to control the wording effect, supported a unidimensional factor struc-ture of the BFNE. Both EFA and CFA supported the unidimensional assumption of the BFNE-S. The correlations of the BFNE and BFNE-S were 0.929 and 0.952 in two samples. The Chinese versions of the BFNE and BFNE-S demonstrate adequate psychometric properties for assessing fear of negative evaluation. The results support their use among the Chinese middle school students. Considering its greater parsimony and excellent reliability and validity, the BFNE-S is a better tool.

    Measuring the quality of care as experienced by patients is increasingly recognised as a way of improving healthcare services. However, disease-specific measures that take the patient journey into account are needed. This paper presents the development of such a measure for patients with heart disease and details the psychometric evaluation. The questionnaire was developed based on a literature review, qualitative interviews and a pilot-test. The psychometric evaluation of the measure was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), Cronbach's alpha coefficient and differential item functioning analysis with data from a population-based survey. Denmark in 2013-2014. Nineteen heart patients, four relatives and eight health professionals participated in qualitative interviews in the development phase, and 15 patients participated in the pilot-test. The questionnaire was subsequently sent to a random sample of 5000 heart patients who were diagnosed in 2013. The comprehensive development phase and pilot-testing contributed to high content validity of the questionnaire. Eligible questionnaire responses were received from 2496 patients. EFA indicated a nine-factor model: communication at the hospital, communication with the general practitioner, information on disease and treatment, information on psychosocial aspects, rehabilitation/support, organisation, medication, involvement of relatives and consideration of comorbidity. CFA confirmed the proposed factor structure (eg, goodness-of-fit index=0.88, adjusted goodness-of-fit index=0.86, root mean square error of approximation=0.05), and Cronbach's alpha coefficient revealed good internal consistency of the factors (range: 0.69-0.93). The results suggest that this disease-specific patient-reported experience measure is of good quality when measuring the quality of care among heart patients. The inclusion of patients in the development phase contributed to high content validity

    Full Text Available The 12-item brief version of the Fear of Negative Evaluation Scale (BFNE is one of the most widely used instruments to assess fear of negative evaluation. Recent evidence strongly supports the version composed of 8 straightforward items (BFNE-S, which possessesstronger psychometric properties. The purpose of the current study is to examine the psychometric prop-erties of the Chinese versions of the BFNE and BFNE-S for middle school students.A total of 1009 middle school students were recruited in this study. The BFNE, the BFNE-S, the Friedman-Bendas Text Anxiety Scale (FBTAS, and the Social Anxiety Scale (SAS were administered to 497 participants, and 52 participants were re-tested after four weeks. The BFNE, the BFNE-S, the Rosenberg Self-Esteem Scale (RSES, and the Balanced Inventory of Desirable Responding (BIDR wereadministered to 492 participants. The BFNE and BFNE-S significantly cor-related with all the scales, supporting their convergent, divergent and concurrent validity.The Cronbach's alpha of the BFNE (BFNE-S was 0.864 (0.867 with 497 par-ticipants and 0.886 (0.844 with 492 participants, and the test-retest reliability coefficient was 0.791 (0.855 (ICC. Although the EFA identified a two-factor solution in which the 8 straightfor-ward items loaded on one factor and the 4 reversed items loaded on the other, the CFA, using a random intercept model to control the wording effect, supported a unidimensional factor struc-ture of the BFNE. Both EFA and CFA supported the unidimensional assumption of the BFNE-S. The correlations of the BFNE and BFNE-S were 0.929 and 0.952 in two samples.The Chinese versions of the BFNE and BFNE-S demonstrate adequate psychometric properties for assessing fear of negative evaluation. The results support their use among the Chinese middle school students. Considering its greater parsimony and excellent reliability and validity, the BFNE-S is a better tool.

    In-depth interviews and focus group discussions were conducted to inform the development of an instrument to measure the health-related quality of life of children living with HIV. The QOL-CHAI instrument consists of four generic core scales of the "Pediatric Quality of Life Inventory" and two HIV-targeted scales-"symptoms" and "discrimination." A piloting exercise involving groups of children living with HIV and HIV-negative children born to HIV-infected parents provided evidence for the acceptable psychometric properties and usability of the instrument. It is expected that the QOL-CHAI can serve well as a brief, standardized, and culturally appropriate instrument for assessing health-related quality of life of Indian children living with HIV.

    2018-06-01

    Individuals with fragile X syndrome (FXS), especially those co-diagnosed with autism spectrum disorder (ASD), face many sensory processing challenges. However, sensory processing measures informed by neurophysiology are lacking. This paper describes the development and psychometric properties of a parent/caregiver report, the Brain-Body Center Sensory Scales (BBCSS), based on Polyvagal Theory. Parents/guardians reported on 333 individuals with FXS, 41% with ASD features. Factor structure using a split-sample exploratory-confirmatory design conformed to neurophysiological predictions. Internal consistency, test-retest, and inter-rater reliability were good to excellent. BBCSS subscales converged with the Sensory Profile and Sensory Experiences Questionnaire. However, data also suggest that BBCSS subscales reflect unique features related to sensory processing. Individuals with FXS and ASD features displayed more sensory challenges on most subscales.

    The Social Interaction Anxiety Scale and Social Phobia Scale are widely used measures of social anxiety. Using data from individuals with social anxiety disorder (n = 435) and nonanxious controls (n = 86), we assessed the psychometric properties of two independently developed short forms of these scales. Indices of convergent and discriminant validity, diagnostic specificity, sensitivity to treatment, and readability were examined. Comparisons of the two sets of short forms to each other and the original long forms were conducted. Both sets of scales demonstrated adequate internal consistency in the patient sample, showed expected patterns of correlation with measures of related and unrelated constructs, adequately discriminated individuals with social anxiety disorder from those without, and showed decreases in scores over the course of cognitive-behavioral therapy and/or pharmacotherapy. However, some significant differences in scale performance were noted. Implications for the clinical assessment of social anxiety are discussed. © The Author(s) 2014.

    Full Text Available “Reading the Mind in the Eyes” test (RMET is one of the most popular and widely used measures of individual differences in Theory of Mind (ToM capabilities. Despite demonstrating good validity in differentiating various clinical groups exhibiting ToM deficits from unimpaired controls, previous studies raised the question of the RMET’s homogeneity, latent structure, and reliability. The aim of this study is to provide evidence on psychometric properties, latent structure, and validity of the newly adapted Serbian version of the RMET. In total, 260 participants (61.9% females took part in the study. The sample consisted of both unimpaired controls (76.5%, and a clinical group of participants that are believed to demonstrate ToM deficits (23.5%, namely, persons diagnosed with schizophrenia and bipolar disorder (54.1% females. RMET has demonstrated fair psychometric properties (KMO = .723; α = .747; H1 = .076; H5 = .465, successfully differentiating between clinical group and control [F (1,254 = 26.175, p <.001, η2 p = .093], while typical gender differences in performance were found only in control group. Tests of several models based on the previous literature revealed that the affect-specific factors underlying performance on RMET demonstrate poor fit. The best fitting model obtained included reduced scale with a single-factor underlying the test’s performance (TLI = .953, CFI = .958, RMSEA = .020. Based on the fit parameters we propose 18-item short-form of the Serbian version of RMET (KMO = .797; α = .728; H1 = .129; H5 = .677 for economic, reliable and valid measurement of ToM abilities.

    The Purdue Pharmacist Directive Guidance (PPDG) Scale was developed to assess patients' perceptions of the level of pharmacist-provided (1) instruction and (2) feedback and goal-setting-2 aspects of pharmaceutical care. Calculations of its psychometric properties stemming from SPSS and R were similar, but distinct differences were apparent. Using SPSS and R software packages, researchers aimed to examine the construct validity of the PPDG using a higher order factoring procedure; in tandem, McDonald's omega and Cronbach's alpha were calculated as means of reliability analyses. Ninety-nine patients with either type I or type II diabetes, aged 18 years or older, able to read and write English, and who could provide written-informed consent participated in the study. Data were collected in 8 community pharmacies in New Mexico. Using R, (1) a principal axis factor analysis with promax (oblique) rotation was conducted, (2) a Schmid-Leiman transformation was attained, and (3) McDonald's omega and Cronbach's alpha were computed. Using SPSS, subscale findings were validated by conducting a principal axis factor analysis with promax rotation; strict parallels and Cronbach's alpha reliabilities were calculated. McDonald's omega and Cronbach's alpha were robust, with coefficients greater than 0.90; principal axis factor analysis with promax rotation revealed construct similarities with an overall general factor emerging from R. Further subjecting the PPDG to rigorous psychometric testing revealed stronger quantitative support of the overall general factor of directive guidance and subscales of instruction and feedback and goal-setting.

    Headache disorders are both common and burdensome but, given the many people affected, provision of health care to all is challenging. Structured headache services based in primary care are the most efficient, equitable and cost-effective solution but place responsibility for managing most patients on health-care providers with limited training in headache care. The development of practical management aids for primary care is therefore a purpose of the Global Campaign against Headache. This manuscript presents an outcome measure, the Headache Under-Response to Treatment (HURT) questionnaire, describing its purpose, development, psychometric evaluation and assessment for clinical utility. The objective was a simple-to-use instrument that would both assess outcome and provide guidance to improving outcome, having utility across the range of headache disorders, across clinical settings and across countries and cultures. After literature review, an expert consensus group drawn from all six world regions formulated HURT through item development and item reduction using item-response theory. Using the American Migraine Prevalence and Prevention Study's general-population respondent panel, two mailed surveys assessed the psychometric properties of HURT, comparing it with other instruments as external validators. Reliability was assessed in patients in two culturally-contrasting clinical settings: headache specialist centres in Europe (n = 159) and primary-care centres in Saudi Arabia (n = 40). Clinical utility was assessed in similar settings (Europe n = 201; Saudi Arabia n = 342). The final instrument, an 8-item self-administered questionnaire, addressed headache frequency, disability, medication use and effect, patients' perceptions of headache "control" and their understanding of their diagnoses. Psychometric evaluation revealed a two-factor model (headache frequency, disability and medication use; and medication efficacy and headache control), with

    This study aims at evaluating the psychometric properties of the antisocial personality disorder (ASPD) criteria in a large sample of patients, most of whom had one or more personality disorders (PD). PD diagnoses were assessed by experienced clinicians using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Axis II PDs. Analyses were performed within an item response theory framework. Results of the analyses indicated that ASPD is a unidimensional construct that can be measured reliably at the upper range of the latent trait scale. Differential item functioning across gender was restricted to two criteria and had little impact on the latent ASPD trait level. Patients fulfilling both the adult ASPD criteria and the conduct disorder criteria had similar latent trait distributions as patients fulfilling only the adult ASPD criteria. Overall, the ASPD items fit the purpose of a diagnostic instrument well, that is, distinguishing patients with moderate from those with high antisocial personality scores.

    To prevent complications from peripheral vascular access device (PVAD) therapy, the Infusion Nurses Society (INS) developed 2 scales to measure the extent and severity of phlebitis and infiltration in PVADs. This study evaluated the psychometric properties of these scales to validate them with respect to their interrater reliability, concurrent validity, feasibility, and acceptability. A total of 182 patients at 2 sites were enrolled, and 416 observations of PVAD sites were made. Two nurses independently rated each PVAD site for the presence or absence of phlebitis and/or infiltration by using the INS scales. The interrater reliability was calculated, as was the agreement of the observed versus charted incidence of phlebitis and infiltration (concurrent validity) and the ease of use of the scales (feasibility, acceptability). Interrater reliability for both the Phlebitis and Infiltration scales and concurrent validity were found to be statistically significant (P Phlebitis and Infiltration scales have been shown to be easy to use, valid, and reliable scales.

  20. Preliminary evaluation of DOE-NEPA monitoring system

    International Nuclear Information System (INIS)

    1981-01-01

    The objective of this analysis was to perform a preliminary investigation of the problems involved in designing a Department of Energy-National Environmental Policy Act (DOE-NEPA) compliance monitoring system. The requirement for such a system arose from the Council on Environmental Quality (CEQ-NEPA regulation effective July 30, 1979. The CEQ regulation uses the term monitoring to denote any method by which the lead agency can assure implementation of Environmental Impact Statement (EIS) and Record of Decision (ROD) environmental mitigation commitments. Monitoring is required for mitigation measures in important cases and may be carried out at agency discretion for all other cases. No definition of important is given in the regulation. The NEPA intent is that all environmental information and planning be incorporated into the decision process as early as possible. In keeping with this concept, any monitoring or enforcement program for a mitigation measure is expected to be adopted and briefly and concisely described in the ROD. Information is presented in four chapters entitled: federal and state compliance monitoring surveys; EIS information analysis; enforcement mechanisms; and administrative practice

    The amount of functioning renal parenchyma can be estimated by MRI by considering the ratio between the mean intensities of cortical and medullar zones of the kidney. Fifty-six patients and 5 healthy volunteers were studied by MRI in our department. Scanning was performed with a superconductive magnet system operating at 0.5 Tesla. Pulse sequence was Spin-Echo with TR 300/TE 30 ms. The cortimedullary ratio (CMR) and differentiation (CMD) were standardized and related with creatine blood levels. CMR data ranged from 1.05 to 3.00, while CMD data ranged from 0.04 to 0.50. High values (good cortico-medullary contrast) were observed in subjects with normal renal function. Patients with renal diseases had low CMR and CMD, proportionally to the degree of renal failure, as proved by laboratory findings. Our preliminary study seems to demonstrate that MRI is an useful technique in the follow-up of patients with chronic renal disease. 19 refs.

    We aim to provide data on a diabetes technology simulation course (DTSC) that instructs internal medicine residents in the use of continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring system (CGMS) devices. The DTSC was implemented during calendar year 2012 and conducted in the institution's simulation center. It consisted of a set of prerequisites, a practicum, and completion of a web-based inpatient CSII-ordering simulation. DTSC participants included only those residents in the outpatient endocrinology rotation. Questionnaires were used to determine whether course objectives were met and to assess the satisfaction of residents with the course. Questionnaires were also administered before and after the endocrine rotation to gauge improvement in familiarity with CSII and CGMS technologies. During the first year, 12 of 12 residents in the outpatient endocrinology rotation completed the DTSC. Residents reported that the course objectives were fully met. The mean satisfaction score with the course ranged from 4.0 to 4.9 (maximum, 5), with most variables rated above 4.5. Self-reported familiarity with the operation of CSII and CGMS devices increased significantly in the postrotation survey compared with that on the prerotation survey (both p technologies. In light of these preliminary findings, the course will continue to be offered, with further data accrual. Future work will involve piloting the DTSC approach among other types of providers, such as residents in other specialties or inpatient nursing staff. © 2013 Diabetes Technology Society.

    Full Text Available Abstract Background Complaints of Arm Neck and Shoulder (CANS represent a wide range of complaints, which can differ in severity from mild, periodic symptoms to severe, chronic and debilitating conditions. They are thought to be associated with both physical and psychosocial risk factors. The measurement and identification of the various risk factors for these complaints is an important step towards recognizing (a high risk subgroups that are relevant in profiling CANS; and (b also for developing targeted and effective intervention plans for treatment. The purpose of the present study was to investigate the prevalence of CANS in a Dutch population of computer workers and to develop a questionnaire aimed at measuring workplace physical and psychosocial risk factors for the presence of these complaints. Methods To examine potential workplace risk factors for the presence of CANS, the Maastricht Upper Extremity Questionnaire (MUEQ, a structured questionnaire, was developed and tested among 264 computer office workers of a branch office of the national social security institution in the Netherlands. The MUEQ holds 95 items covering demographic characteristics, in addition to seven main domains assessing potential risk factors with regard to (1 work station, (2 posture during work, (3 quality of break time, (4 job demands, (5 job control, and (6 social support. The MUEQ further contained some additional questions about the quality of the work environment and the presence of complaints in the neck, shoulder, upper and lower arm, elbow, hand and wrist. The prevalence rates of CANS in the past year were computed. Further, we investigated the psychometric properties of the MUEQ (i.e. factor structure and reliability. Results The one-year prevalence rate of CANS indicated that 54% of the respondents reported at least one complaint in the arm, neck and/or shoulder. The highest prevalence rates were found for neck and shoulder symptoms (33% and 31

    The current study sought to establish the psychometric properties of the revised Sibling Cancer Needs Instrument (SCNI) when completed by young people who have a brother or sister with cancer. The participants were 106 young people aged between 12 and 24 who had a living brother or sister diagnosed with any type or stage of cancer in the last 5 years. They were recruited from multiple settings. The initial step in determining the dimensional structure of the questionnaire was exploratory factor analysis and further assessment followed using Rasch analysis. Construct validity and test-retest reliability (n = 17) were also assessed. The final SCNI has 45 items and seven domains: information; practical assistance; "time out" and recreation; feelings; support (friends and other young people); understanding from my family; and sibling relationship. There was a reasonable spread of responses across the scale for every item. Rasch analysis results suggested that overall, respondents used the scale consistently. Support for construct validity was provided by the correlations between psychological distress and the SCNI domains. The internal consistency was good to excellent; Cronbach's alphas ranged from 0.78 to 0.94. The test-retest reliability of the overall measure is 0.88. The SCNI is the first measure of psychosocial unmet needs which has been developed for young people who have a brother or sister with cancer. The sound psychometric properties allow the instrument to be used with confidence. The measure will provide a substantial clinical benefit in highlighting the unmet needs of this population to assist with the prioritisation of targeted supportive care services and evaluating the impact of interventions targeted at siblings.

    The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) is considered a valid instrument for use in Brazil. However, the previous Brazilian validation study included only 30 lung cancer patients and only measured test-retest reliability. The aim of this study was to evaluate the psychometric properties of the EORTC QLQ-C30 in a sample of cancer patients at different educational levels who completed the instrument administered by an interviewer. Data from six prospective studies conducted by the same group of researchers were combined in this study (N = 986). Reliability was assessed using Cronbach's alpha coefficient, all values of which were >0.7, with the exception of cognitive functioning, social functioning, and nausea and vomiting (α = 0.57, α = 0.69, and α = 0.68, respectively). In multi-trait scaling analysis, convergent and divergent validity were considered adequate (validity indices were 91.6 and 97.4%). In general, moderate to strong correlations were found between the subscales of the EORTC QLQ-C30 and its respective dimensions from the WHOQOL-bref, the hospital anxiety and depression scale, and the Edmonton Symptom Assessment System (ESAS) instruments. In addition, the EORTC QLQ-C30 was able to differentiate groups of patients with distinct performance statuses and types of treatment (known-group validation). Statistical analyses were also performed on educational status, yielding similar results. Detailed psychometric property data using the EORTC QLQ-C30 in Brazil are added by this study. In addition, we demonstrated that this instrument is in general reliable and valid regardless of the patient educational level.

    Highlights: • The basic information of a Chinese SCWR concept CSR1000 is introduced. • An innovative passive safety system is proposed for CSR1000. • 6 Transients and 3 accidents are analysed with system code SCTRAN. • The passive safety systems greatly mitigate the consequences of these incidents. • The inherent safety of CSR1000 is enhanced. - Abstract: This paper describes the preliminary safety analysis of the Chinese Supercritical water cooled Reactor (CSR1000), which is proposed by Nuclear Power Institute of China (NPIC). The two-pass core design applied to CSR1000 decreases the fuel cladding temperature and flattens the power distribution of the core at normal operation condition. Each fuel assembly is made up of four sub-assemblies with downward-flow water rods, which is favorable to the core cooling during abnormal conditions due to the large water inventory of the water rods. Additionally, a passive safety system is proposed for CSR1000 to increase the safety reliability at abnormal conditions. In this paper, accidents of “pump seizure”, “loss of coolant flow accidents (LOFA)”, “core depressurization”, as well as some typical transients are analysed with code SCTRAN, which is a one-dimensional safety analysis code for SCWRs. The results indicate that the maximum cladding surface temperatures (MCST), which is the most important safety criterion, of the both passes in the mentioned incidents are all below the safety criterion by a large margin. The sensitivity analyses of the delay time of RCPs trip in “loss of offsite power” and the delay time of RMT actuation in “loss of coolant flowrate” were also included in this paper. The analyses have shown that the core design of CSR1000 is feasible and the proposed passive safety system is capable of mitigating the consequences of the selected abnormalities

    Polyhexamethylene guanidine hydrochloride (PHMGH) is used worldwide as an antimicrobial agent with broad spectra of activity and also for treating pool water. This non-GLP preliminary study aims at investigating in a subchronic toxicity study possible effects at supra-optimal doses of this biocide. Both acute and subchronic toxicity studies were conducted. LD(50) for PHMGH was estimated to be 600 mg/kg (ie LC(50) 2 ml of 7.5% solution) when administered as a single dose by gavage via a stomach tube in accordance with the expected route of administration. The acute studies showed that the median lethal dose (LD(50)) of 600 mg/kg was accompanied by signs of neurotoxicity. Haematological and biochemical parameters of subchronic toxicity studies were non-significant. Subchronic doses of 0.006 mg/kg, 0.012 mg/kg and 0.036 mg/kg were administered. 20% of the animals at a dose of 0.006 mg/kg and 0.036 mg/kg showed mild degrees of hydropic changes in proximal tubules while 10% of animals at all the doses had their liver tissues showing local areas of mild pericentral hepatocytes degeneration. PHMGH did not produce any major organ defect with regard to the kidney, heart, and liver. The LD(50) was much higher than the recommended dosage by a factor of about 50,000. The recommended residual concentration is far less than the median lethal dose using rats as test subjects. These results could serve as a basis for investigating the full toxicological profile if it is to be used for the treatment of raw water to make it potable. © The Author(s) 2014.

    Full Text Available This study sought to establish the psychometric properties of a Coping Strategies Inventory Short Form (CSISF by examining coping skills in the Jackson Heart Study cohort. We used exploratory and confirmatory factor analysis, Pearson’s correlation, and Cronbach Alpha to examine reliability and validity in the CSI-SF that solicited responses from 5302 African American men and women between the ages of 35 and 84. One item was dropped from the 16-item CSI-SF, making it a 15-item survey. No significant effects were found for age and gender, strengthening the generalizability of the CSI-SF. The internal consistency reliability analysis revealed reliability between alpha = 0.58-0.72 for all of the scales, and all of the fit indices used to examine the CSI-SF provided support for its use as an adequate measure of coping. This study provides empirical support for utilizing this instrument in future efforts to understand the role of coping in moderating health outcomes.

    Disputes exist regarding the psychometric properties of the Oswestry Disability Index (ODI). The present study was to examine the reliability, validity, and dimensionality of a Chinese version of the ODI version 2.1 in a sample of 225 adult orthopedic outpatients with chronic low back pain [mean age (SD): 40.7 (11.4) years]. We conducted reliability analysis, exploratory bifactor analysis, confirmatory factor analysis, and Mokken scale analysis of the ODI. To validate the ODI, we used the Short-Form 36 questionnaire (SF-36) and visual analog scale (VAS). The reliability, and discriminant and construct validities of the ODI was good. The fit statistics of the unidimensional model of the ODI were inadequate. The ODI was a weak Mokken scale (H s  = 0.31). The ODI was a reliable and valid scale suitable for measurement of disability in patients with low back pain. But the ODI seemed to be multidimensional that was against the use of the raw score of the ODI as a measurement of disability.

    Resilience refers to the ability to effectively cope and positively adapt after adversity or trauma. This study investigated the factor structure and psychometric properties of the Chinese version of the Resilience Scale (RS) for college students with Wenchuan earthquake exposure. A total of 888 Chinese college students with Wenchuan earthquake exposure completed a set of scales, including the RS, the Post-traumatic Stress Disorder Self-rating Scale, the Zung Self-rating Depression Scale, the Zung Self-rating Anxiety Scale, and the Eysenck Personality Questionnaire Short Scale for Chinese. The internal consistency and concurrent validity were investigated. Sex and regional differences were also examined. The results of exploratory factor analysis and confirmatory factor analysis showed that the 4-factor structure was suitable for both Chinese samples 1 and 2. The Cronbach α coefficient was .94 (P split-half reliability coefficient was .92 (P disorder (r = -0.21; P < .01), depression (r = -0.45; P < .01), anxiety(r = -0.34; P < .01), and neuroticism (r = -0.23; P < .01), and correlated positively with extraversion (r = 0.23; P < .01). Men showed higher resilience scores than women, and people living in the high earthquake-exposure areas reported higher level of resilience than those from low earthquake-exposure areas. The Chinese version of the RS was demonstrated to be a reliable and valid measurement in assessing resilience for Wenchuan earthquake survivors. Copyright © 2012 Elsevier Inc. All rights reserved.

    Although there are widely accepted and utilized models and frameworks for nondirective counseling (NDC), there is little in the way of tools or instruments designed to assist in determining whether or not a specific episode of counseling is consistent with the stated model or framework. The Counseling Progress and Depth Rating Instrument (CPDRI) was developed to evaluate counselor integrity in the use of Egan's skilled helper model in online counseling. The instrument was found to have sound internal consistency, good interrater reliability, and good face and convergent validity. The CPDRI is, therefore, proposed as a useful tool to facilitate investigation of the degree to which counselors adhere to and apply a widely used approach to NDC.

    To develop the Korean version of the Participation and Environment Measure for Children and Youth (KPEM-CY) and examine its psychometric properties. The PEM-CY was cross-culturally translated into Korean using a specific guideline: pre-review of participation items, forward/backward translation, expert committee review, pre-test of the KPEM-CY and final review. To establish internal consistency, test-retest reliability and construct validity of the KPEM-CY, 80 parents of children with disabilities aged 5-13 years were recruited in South Korea. Across the home, school and community settings, 76% of participation items and 29% of environment items were revised to improve their fit with Korean culture. Internal consistency was moderate to excellent (0.67-0.92) for different summary scores. Test-retest reliability was excellent (>0.75) in the summary scores of participation frequency and extent of involvement across the three settings and moderate to excellent (0.53-0.95) in all summary scores at home. Child's age, type of school and annual income were the factors that significantly influenced specific dimensions of participation and environment across all settings. Results indicated that the KPEM-CY is equivalent to the original PEM-CY and has initial evidence of reliability and validity for use with Korean children with disabilities. Implications for rehabilitation Because 'participation' is a key outcome of the rehabilitation, measuring comprehensive participation of children with disabilities is necessary. The PEM-CY is a parent-report survey measure to assess comprehensive participation of children and youth and environment, which affect their participation, at home, school and in the community. A cross-cultural adaptation process is mandatory to adapt the measurement tool to a new culture or country. The Korean PEM-CY has both reliability and validity and can therefore generate useful clinical data for Korean children with disabilities.

    Recent increases in the number of online gambling sites have made gambling more available, which may contribute to an increase in gambling problems. At the same time, online gambling provides opportunities to introduce measures intended to prevent problem gambling. GamTest is an online test of gambling behavior that provides information that can be used to give players individualized feedback and recommendations for action. The aim of this study is to explore the dimensionality of GamTest and validate it against the Problem Gambling Severity Index (PGSI) and the gambler's own perceived problems. A recent psychometric approach, exploratory structural equation modeling (ESEM) is used. Well-defined constructs are identified in a two-step procedure fitting a traditional exploratory factor analysis model as well as a so-called bifactor model. Using data collected at four Nordic gambling sites in the autumn of 2009 (n = 10,402), the GamTest ESEM analyses indicate high correspondence with the players' own understanding of their problems and with the PGSI, a validated measure of problem gambling. We conclude that GamTest captures five dimensions of problematic gambling (i.e., overconsumption of money and time, and monetary, social and emotional negative consequences) with high reliability, and that the bifactor approach, composed of a general factor and specific residual factors, reproduces all these factors except one, the negative consequences emotional factor, which contributes to the dominant part of the general factor. The results underscore the importance of tailoring feedback and support to online gamblers with a particular focus on how to handle emotions in relation to their gambling behavior.

    A questionnaire was developed and validated which assesses factors influencing career choices of medical students and their perception of possibilities in general practice. The first questionnaire version, which was developed based on a systematic literature review, was checked for comprehensibility and redundancy using concurrent think aloud. The revised version was filled out by a pilot sample of medical students and the factor structure was assessed using principal component analysis (PCA). The final version was filled out in an online survey by medical students of all 5 Medical Faculties in the federal state of Baden-Wuerttemberg. The factor structure was validated with a confirmatory factor analysis (CFA). Reliability was assessed as internal consistency using Cronbach's α. The questionnaire comprises 2 parts: ratings of (A) the individual importance and of (B) the possibilities in general practice on 5-point scales. The first version comprising 118 items was shortened to 63 items after conducting interviews using concurrent think aloud. A further 3 items giving no information were removed after piloting the questionnaire on 179 students. The 27 items of part A were structured in 7 factors (PCA): image, personal ambition, patient orientation, work-life balance, future perspectives, job-related ambition, and variety in job. This structure had a critical fit in the CFA applied to the final version filled out by 1 299 students. Internal consistency of the factors was satisfactory to very good (Cronbach's α=0.55-0.81). The questionnaire showed good psychometric properties. Further, not assessed factors influence career choice resulting in unexplained variance in our dataset and the critical fit of the model. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available The current study investigated the psychometric properties of the Persian translation of the Mate Retention Inventory–Short Form (MRI-SF in Iran. We also investigated sex differences in the use of mate retention tactics and investigated the relationships between mate retention behaviors and a number of related cultural constructs. Participants (N = 308 ranged in age from 18 to 57 years. All participants were in a committed romantic relationship, with mean relationship length of 63.5 months (SD = 73.8. Participants completed the Persian translation of the MRI-SF and measures of religiosity, relationship satisfaction, self-esteem, and socioeconomic status. Cultural measures specific to Iran were also included, such as Mahr (for married individuals, self-perceived Qeiratiness (for men, and self-perceived jealousy (for women. Mahr is a mandatory amount of money or possessions paid or promised to be paid by the groom to the bride at the time of the marriage contract. Qeirati is a male-specific adjective in Persian meaning protective against unwanted attention toward a man’s romantic partner. Female jealousy is usually regarded the counterpart of male Qeiratiness in Iranian culture. The 19 mate retention tactics formed a two-component structure, consistent with previous research. Results demonstrate adequate internal consistency of 2-item assessments of mate retention tactics. Observed sex differences accorded with previous mate retention research and are discussed in reference to evolutionary perspectives on human mating. Several significant associations emerged between mate retention tactics and Iranian culture-specific variables and are discussed from a cross-cultural perspective.

  8. Preliminary evaluation of alterant geophysical tomography in welded tuff

    1985-01-01

    The ability of alterant geophysical tomography to delineate flow paths in a welded tuff rock mass has been preliminarily evaluated based on the results of a field experiment. Electromagnetic measurements were made before, during and after a water-based, dye tracer flowed through the rock mass. Alterant geophysical tomographs were generated and compared with independent evidence - borescope logs, neutron logs and dyed rock samples. Anomalies present in the tomograph match the location and orientation of fractures mapped with a borescope. The location of tracer-stained fractures coincides with the location of some image anomalies; other geophysical anomalies exist where tracer-stained fractures were not observed, perhaps due to poor core recovery. Additional drilling to locate stained flow paths and other experiments are planned so that the applicability of the technique can be further evaluated

    2009-09-01

    The work aimed at analyzing results of kinesitherapeutic procedures in patients with cervical vertigo as well as evaluating a mobility range of the cervical spine. The study was conducted on 23 people, including 17 women and 6 men suffering from cervical vertigo, at the age of 23-73 (the average age of 49.5). All the patients had an individually selected cycle of kinesitherapeutic exercises through the period of 2 months. The objective efficiency evaluation of the applied therapy was made on the grounds of the videonystagmographic examination (VNG). Additionally, the range of active mobility of the cervical spine was analyzed and the evaluation of vertigo according to Silvoniemi's criteria was performed. After a 2-month therapy 4 patients (17.4%) out of the examined material showed a total lack of vertigo, 15 patients (65.2%) demonstrated a meaningful decrease in the vertigo intensity, also in the frequency of their occurrence in 14 cases (60.8%). Only 3 patients did not show any decrease in vertigo whereas in 1 patient a slight increase in the intensity was indicated. On the basis of a subjective evaluation of the vertigo increase according to the 5-stage Silvoniemi's scale it was proved that a mean point assessment claimed by the patients at the beginning of the therapy amounts to 3.0 points whereas after the therapy it was as follows: 1.43 pt after 2 weeks, 1.17 pt after 1 month and 1.13 pt after 2 months of kinesitherapy. It is extremely difficult to fully eliminate the symptoms of cervical vertigo (in the studied material in 4 cases--17.3%) because the causes of their occurrence, which are connected with excessive tension and degeneration in the cervical spine, cannot usually be eradicated. Additionally, as a diagnostic means, the videonystagmographic examination (VNG) accompanied by the positioning tests and the cervical rotation test facilitates precise and objective monitoring of the progress in treatment and rehabilitation of vertigo.

    1995-02-01

    We have conducted an evaluation of two high efficiency steel filters in the exhaust of an uranium oxide grit blaster at the Y-12 Plant in Oak Ridge Tennessee. The filters were installed in a specially designed filter housing with a reverse air-pulse cleaning system for automatically cleaning the filters in-place. Previous tests conducted on the same filters and housing at LLNL under controlled conditions using Arizona road dust showed good cleanability with reverse air pulses. Two high efficiency steel filters, containing 64 pleated cartridge elements housed in the standard 2` x 2` x 1` HEPA frame, were evaluated in the filter test housing using a 1,000 cfm slip stream containing a high concentration of depleted uranium oxide dust. One filter had the pleated cartridges manufactured to our specifications by the Pall Corporation and the other by Memtec Corporation. Test results showed both filters had a rapid increase in pressure drop with time, and reverse air pulses could not decrease the pressure drop. We suspected moisture accumulation in the filters was the problem since there were heavy rains during the evaluations, and the pressure drop of the Memtec filter decreased dramatically after passing clean, dry air through the filter and after the filter sat idle for one week. Subsequent laboratory tests on a single filter cartridge confirmed that water accumulation in the filter was responsible for the increase in filter pressure drop and the inability to lower the pressure drop by reverse air pulses. No effort was made to identify the source of the water accumulation and correct the problem because the available funds were exhausted.

    Purpose. To evaluate an innovative surgical technique for phaco-ersatz, a cataract surgery designed to restore accommodation. Techniques for very small capsulorhexis as well as the refilling procedure were developed. This study evaluates the feasibility and reproducibility of the surgical technique. Methods. The right eye of 8 NZW rabbits (~ 2 Kg) were operated following the ARVO Statements for the Use of Animals in Ophthalmic and Vision Research. The surgery is begun by making a small peripheral capsulorhexis of about 1 mm using. The lens content is then removed. The lens is then refilled with a novel in situ polymerizable gel and the corneal incision is closed using one 10/0 Nylon interrupted stitch. Results. The capsulorhexis technique was succesfully performed and reproducible in all animals. The average size of the capsulorhexis opening was 1. 2 mm (+/-0.14). Lens material removal and refilling of the capsular bag with an in situ polymerizable material was also performed in each trial study. Conclusion. This surgical technique seemed feasible and reproducible.

For example, the use of computerized audits has increased, cooling and baseload measures have been added, weatherization approaches tailored to the unique construction characteristics of mobile homes have been developed, the weatherization of large multifamily buildings has expanded and become more sophisticated, the flexibility to improve 'energy-related' health and safety has been provided, and leveraging with utilities, other state programs, and owners of large multifamily buildings has increased considerably. The Department of Energy tasked ORNL with planning the new evaluation in light of its experience in conducting the previous national evaluation and the metaevaluations. This preliminary evaluation plan, developed by ORNL, documents how the new national evaluation will be performed. In the remaining portion of this section, the purpose and fundamental questions the evaluation will address are identified and how these questions were derived is discussed.

  18. SELECTION AND PRELIMINARY EVALUATION OF ALTERNATIVE REDUCTANTS FOR SRAT PROCESSING

    Energy Technology Data Exchange (ETDEWEB)

    Stone, M.; Pickenheim, B.; Peeler, D.

    2009-06-30

    Defense Waste Processing Facility - Engineering (DWPF-E) has requested the Savannah River National Laboratory (SRNL) to perform scoping evaluations of alternative flowsheets with the primary focus on alternatives to formic acid during Chemical Process Cell (CPC) processing. The reductants shown below were selected for testing during the evaluation of alternative reductants for Sludge Receipt and Adjustment Tank (SRAT) processing. The reductants fall into two general categories: reducing acids and non-acidic reducing agents. Reducing acids were selected as direct replacements for formic acid to reduce mercury in the SRAT, to acidify the sludge, and to balance the melter REDuction/OXidation potential (REDOX). Non-acidic reductants were selected as melter reductants and would not be able to reduce mercury in the SRAT. Sugar was not tested during this scoping evaluation as previous work has already been conducted on the use of sugar with DWPF feeds. Based on the testing performed, the only viable short-term path to mitigating hydrogen generation in the CPC is replacement of formic acid with a mixture of glycolic and formic acids. An experiment using glycolic acid blended with formic on an 80:20 molar basis was able to reduce mercury, while also targeting a predicted REDuction/OXidation (REDOX) of 0.2 expressed as Fe{sup 2+}/{Sigma}Fe. Based on this result, SRNL recommends performing a complete CPC demonstration of the glycolic/formic acid flowsheet followed by a design basis development and documentation. Of the options tested recently and in the past, nitric/glycolic/formic blended acids has the potential for near term implementation in the existing CPC equipment providing rapid throughput improvement. Use of a non-acidic reductant is recommended only if the processing constraints to remove mercury and acidify the sludge acidification are eliminated. The non-acidic reductants (e.g. sugar) will not reduce mercury during CPC processing and sludge acidification would

    Clinicians need brief and valid instruments to monitor the psychosocial impact of weight gain in persons with psychiatric disorders. We examined the psychometric properties of the Spanish version of the Body Weight, Image and Self-Esteem Evaluation (B-WISE) questionnaire in patients with severe mental disorders. The data come from a naturalistic, cross-sectional, validation study conducted at 6 centres in Spain. A total of 211 outpatients with severe mental disorders, 118 with schizophrenia and 93 with bipolar disorder, were evaluated using the B-WISE, the Visual Analogue Scale for Weight and Body Image, and the Clinical Global Impression-Severity (CGI-S). The body mass index was also obtained. The principal component analysis confirms 3 components explaining 50.93% of the variance. The Cronbach α values for B-WISE scales ranged between .55 and .73. Significant Pearson correlations were found between B-WISE total score and CGI-S (r = -0.25; P Body Image (r = 0.47; P Body mass index categorization significantly influenced total B-WISE scores (F = 3.586, P < .050). The B-WISE score corresponding to the 5th and 10th percentiles was 22. We were able to demonstrate that the Spanish version of the B-WISE is a valid instrument for assessing psychosocial impact of weight gain in patients with severe mental disorders in daily clinical practice.

    Full Text Available The first part of this investigation explored the multidimensional nature of product meaning, referring to the variety of connotations and functions a consumer associates with a particular product category. The subsequent experiment examined the moderation effects of product meaning and other attributes of the user on (a the affective evaluation of an obstructed use interaction, and (b the transfer of emotion between devices presented as being either of the same or a different brand. Although the failure experience essentially caused frustration, this reaction varied substantially among consumers depending on product meaning, age, and gender. The results also showed that the emotion dimensions of pleasure, arousal, and dominance were affected in distinct ways, and that, in addition to the consumer variables, transfer was mainly dependent on the brand relation. Nevertheless, user frustration did not cause general brand aversion, indicating that poor designs do not unconditionally threaten the customer relationship.

  1. Preliminary Evaluation of Nonlinear Effects on TCA Flutter

    Arslan, Alan E.; Hartwich, Peter M.; Baker, Myles L.

    1998-01-01

    The objective of this study is to investigate the effect of nonlinear aerodynamics, especially at high angles-of-attack with leading-edge separation, on the TCA flutter properties at transonic speeds. In order to achieve that objective, flutter simulations with Navier-Stokes CFD must be performed. To this end, time-marching Navier-Stokes solutions are computed for the TCA wing/body configuration at high angles-of-attack in transonic flight regimes. The approach is to perform non-linear flutter calculations on the TCA at two angles-of-attack, the first one being a case with attached flow (a=2.8 degrees) and the second one being a high angle-of-attack case with a wing leading edge vortex (a=12.11 degrees). Comparisons of the resulting histories and frequency damping information for both angles-of-attack will evaluate the impact of high-alpha aerodynamics on flutter.

    Sterilization of critical and semicritical instruments used in patient care must undergo a terminal process of sterilization. Use of chemical and physical indicators are important in providing information on the sterilizer's performance during each cycle. Regular and periodic monitoring of sterilizers using biological indicators is necessary in periodically validating performance of sterilizers. Data loggers or independent digital parametric indicators are innovative devices that provide more information than various classes chemical indicators. In this study we evaluated a prototype of an independent digital parametric indicator's use in autoclaves. The purpose of this study was to evaluate the performance of an independent digital indicator/data logger prototype (DS1922F) that could be used for multiple cycles within an autoclave.MG Materials and methods: Three batches of the DS1922F (150 samples) were used in this study that was conducted in a series. The first batch was challenged with 300 sterilization cycles within an autoclave and the data loggers evaluated to study failures and the reason for failure, make corrections and improve the prototype design. After changes made based on studying the first batch, the second batch of the prototype (150 samples) were challenged once again with 300 sterilization cycles within an autoclave and failure studied again in further improvement of the prototype. The final batch (3rd batch) of the prototype (150 samples) was challenged again but with 600 cycles to see how long they would last. Kaplan-Meier survival analysis analyses of all three batches was conducted (α = 0.05) and failed samples qualitatively studied in understanding the variables involved in the failure of the prototype, and in improving quality. Each tested batch provided crucial information on device failure and helped in improvement of the prototype. Mean lifetime survival of the final batch (Batch 3) of prototype was 498 (480, 516) sterilization cycles

    Fatigue is a debilitating condition suffered by many as the result of chronic disease, yet relatively little is known about its biological basis or how to effectively manage its effects. This study sought to evaluate chronic fatigue by using lupus-prone mice and testing them at three different time periods. Lupus-prone mice were chosen because fatigue affects over half of patients with Systemic Lupus Erythematosus. Eleven MLR⁺/(+) (genetic controls) and twelve MLR/MpJ-Fas/J (MRL/lpr; lupus-prone) mice were tested three times: once at 12, 16 and 20 weeks of age. All mice were subjected to a variety of behavioral tests including: forced swim, post-swim grooming, running wheel, and sucrose consumption; five of the MLR⁺/(+) and five of the MLR/lpr mice were also tested on a fixed ratio-25 operant conditioning task. MRL/lpr mice showed more peripheral symptoms of lupus than controls, particularly lymphadenopathy and proteinuria. Lupus mice spent more time floating during the forced swim test and traveled less distance in the running wheel at each testing period. There were no differences between groups in post-swim grooming or in number of reinforcers earned in the operant conditioning task indicating the behavioral changes were not likely due simply to muscle weakness or motivation. Correlations between performance in the running wheel, forced swim test and sucrose consumption were conducted and distance traveled in the running wheel was consistently negatively correlated with time spent floating. Based on these data, we conclude that the lupus-prone mice were experiencing chronic fatigue and that running wheel activity and floating during a forced swim test can be used to evaluate fatigue, although these data cannot rule out the possibility that both fatigue and a depressive-like state were mediating these effects.

    Understanding of the physical, functional and psychosocial health problems and needs of cancer survivors requires cross-national and cross-cultural standardization of health-related quality of life (HRQoL) questionnaires that capture the full range of issues relevant to cancer survivors. To our knowledge, only one study has investigated in a comprehensive way whether a questionnaire used to evaluate HRQoL in cancer patients under active treatment is also reliable and valid when used among (long-term) cancer survivors. In this study we evaluated, in an international context, the psychometrics of HRQoL questionnaires for use among long-term, disease-free, survivors of testicular and prostate cancer. In this cross-sectional study, we recruited long-term survivors of testicular and prostate cancer from Northern and Southern Europe and from the United Kingdom who had participated in two phase III EORTC clinical trials. Participants completed the SF-36 Health Survey, the EORTC QLQ-C30 questionnaire, the QLQ-PR25 (for prostate cancer) or the QLQ-TC26 (for testicular cancer) questionnaires, and the Impact of Cancer questionnaire. Testicular cancer survivors also completed subscales from the Nordic Questionnaire for Monitoring the Age Diverse Workforce. Two hundred forty-two men (66% response rate) were recruited into the study. The average time since treatment was more than 10 years. Overall, there were few missing questionnaire data, although scales related to sexuality, satisfaction with care and relationship concerns of men without partners were missing in more than 10% of cases. Debriefing showed that in general the questionnaires were accepted well. Many of the survivors scored at the upper extremes of the questionnaires, resulting in floor and ceiling effects in 64% of the scales. All of the questionnaires investigated met the threshold of 0.70 for group level reliability, with the exception of the QLQ-TC26 (mean reliability .64) and the QLQ-PR25 (mean reliability

    The aim of this study was to describe the psychometric evaluation of the Orofacial Pain Scale for Non-Verbal Individuals (OPS-NVI) as a screening tool for orofacial pain in people with dementia. The OPS-NVI has recently been developed and needs psychometric evaluation for clinical use in people with dementia. The pain self-report is imperative as a reference standard and can be provided by people with mild-to-moderate cognitive impairment. The presence of orofacial pain during rest, drinking, chewing and oral hygiene care was observed in people with mild cognitive impairment (MCI) and dementia using the OPS-NVI. Participants who were considered to present a reliable self-report were asked about pain presence, and in all participants, the oral health was examined by a dentist for the presence of potential painful conditions. After item-reduction, inter-rater reliability and criterion validity were determined. The presence of orofacial pain in this population was low (0%-10%), resulting in an average Positive Agreement of 0%-100%, an average Negative Agreement of 77%-100%, a sensitivity of 0%-100% and a specificity of 66%-100% for the individual items of the OPS-NVI. At the same time, the presence of oral problems, such as ulcers, tooth root remnants and caries was high (64.5%). The orofacial pain presence in this MCI and dementia population was low, resulting in low scores for average Positive Agreement and sensitivity and high scores for average Negative Agreement and specificity. Therefore, the OPS-NVI in its current form cannot be recommended as a screening tool for orofacial pain in people with MCI and dementia. However, the inter-rater reliability and criterion validity of the individual items in this study provide more insight for the further adjustment of the OPS-NVI for diagnostic use. Notably, oral health problems were frequently present, although no pain was reported or observed, indicating that oral health problems cannot be used as a new reference

    The Students' Resilience and Interpersonal Skills Development Education (STRIDE) is a preventive drug education programme. The rational of this programme is that preventive drug education has to begin early in age, before the development of social attitudes and behaviour of students. A pre and a post intervention surveys were performed to evaluate the impact of this programme. Nine schools from three states were identified to participate in the intervention. These schools were selected based on their locations in high-drug-use areas (where the prevalence of drug use exceeds 0.5% of the student population). The new intervention curriculum was put into practice for three months in the nine schools. The overall scores obtained by each respondent to assess their knowledge on drugs and its implications were analysed. The results showed that the programme made a positive impact from the pre to post intervention programme by using the Wilcoxon Signed Rank Test (p < 0.05). A high percentage of the questions showed significant evidence through the McNemar matched pair Chi-Squared test with Bonferonni correction that there were positive shifts in the answers by comparing the pre and post intervention results (p < 0.05). Recommendations have been discussed with the Ministry of Education to integrate this programme into the national primary school curriculum.

    Phytochemicals are natural bioactive compounds found in plants, such as vegetables, fruits, medicinal plants, flowers, leaves and roots that work with nutrients and fibers to protect against various human diseases. Gynura procumbens or locally known as Sambung Nyawa is a plant species widely planted in many warmer regions. It is a perennial plant of the Asteraceae family, which may grow to 100 cm high with oval-shaped, leaves to 10 cm long and have a rather fleshy feel. Gynura procumbens has been used for the treatment of eruptive fevers, rash and kidney disease. The leaves of this plant continue to be used as folk medicine to control diabetes mellitus and hyperlipidaemia. The aim of this research was to evaluate the presence of phytochemicals constituents in different solvent extracts of Gynura procumbens leaves. Qualitative phytochemicals screening of hexane, chloroform, methanol and water extracts were carried out for the detection of terpenoids, alkaloids, flavonoids, tannins, saponins, steroids, lipids, coumarin, cardiac glycosides and anthraquinones. The phytochemicals screening showed positive results for terpenoids, alkaloids, flavonoids, tannins, saponins, lipids, coumarin and anthraquinones in methanol and water extracts of Gynura procumbens. The diversity of phytochemicals present suggests that Gynura procumbens leaves could serve as a source of useful drugs. (author)

    The anticipated transient without scram (ATWS) is defined as an abnormal transient with failure of scram actuation. It is one of the “worst case” accident based on the United States Nuclear Regulatory Commission (U.S.NRC). Consideration frequently motivates the NRC to take regulatory action. An evaluation of this event is also a general requirement due to a potential safety issue that may lead to core damage under postulated condition. This paper estimated the set-points sensitivity test of the diverse protection system (DPS) related with unprotected events of the prototype generation-IV sodium cooled fast reactor (PGSFR) including unprotected transient over power (UTOP) and unprotected loss of flow (ULOF) by MARS-LMR code. The variation of the power to flow (P/Q) of UTOP and ULOF is illustrated to conduct the set-points sensitivity test of DPS. Also we estimated the effect of the DPS introduction after selecting UTOP, ULOF event as the unprotected events which are predicted to aggravate the events. This paper estimated the set-points sensitivity test of DPS related with unprotected events of PGSFR including UTOP and ULOF by MARS-LMR code. The results indicated that there is no significant difference in both RPS and DPS about the initiating time of each event. Therefore, this study found that the urgent manage for safety of the reactor when RPS failed is possible by the applying DPS

    Procrastination is a prevalent self-regulatory failure associated with stress and anxiety, decreased well-being, and poorer performance in school as well as work. One-fifth of the adult population and half of the student population describe themselves as chronic and severe procrastinators. However, despite the fact that it can become a debilitating condition, valid and reliable self-report measures for assessing the occurrence and severity of procrastination are lacking, particularly for use in a clinical context. The current study explored the usefulness of the Swedish version of three Internet-administered self-report measures for evaluating procrastination; the Pure Procrastination Scale, the Irrational Procrastination Scale, and the Susceptibility to Temptation Scale, all having good psychometric properties in English. In total, 710 participants were recruited for a clinical trial of Internet-based cognitive behavior therapy for procrastination. All of the participants completed the scales as well as self-report measures of depression, anxiety, and quality of life. Principal Component Analysis was performed to assess the factor validity of the scales, and internal consistency and correlations between the scales were also determined. Intraclass Correlation Coefficient, Minimal Detectable Change, and Standard Error of Measurement were calculated for the Irrational Procrastination Scale. The Swedish version of the scales have a similar factor structure as the English version, generated good internal consistencies, with Cronbach's α ranging between .76 to .87, and were moderately to highly intercorrelated. The Irrational Procrastination Scale had an Intraclass Correlation Coefficient of .83, indicating excellent reliability. Furthermore, Standard Error of Measurement was 1.61, and Minimal Detectable Change was 4.47, suggesting that a change of almost five points on the scale is necessary to determine a reliable change in self-reported procrastination severity.

    The effectiveness of cognitive-behaviour therapy with young people may be influenced by a young person's capacity for self-reflection and insight. Clinicians who assess clients' proficiencies in these cognitive capacities can better tailor cognitive and behavioural techniques to the client, facilitating engagement and enhancing treatment outcome. It is therefore important that sound instruments for assessing self-reflection and insight in young people are available. The aim of the current study was to translate and adapt the Self-Reflection and Insight Scale (SRIS) for use with a child and adolescent population (Study 1), and to evaluate the psychometric properties of the resulting measure, the Self-Reflection and Insight Scale for Youth (SRIS-Y; Study 2). In Study 1 (n=145), the comprehensibility of the SRIS-Y was assessed in a community sample of children and adolescents. Study 2 (n=215) then explored the reliability and structural, convergent, and divergent validity of the SRIS-Y. The SRIS-Y was found to be comprehensible to young people, and had good reliability and structural validity. It appears that the SRIS-Y is a sound instrument for assessing therapy-relevant cognitive capacities in young people, of potential benefit in both research and clinical contexts. Future research foci include the predictive validity of the instrument.

    A requisite step for testing cognitive theories regarding the role of self-concept in schizophrenia is the development of measures that follow a cognitive conceptualization and better capture the multifaceted nature of this construct. The purpose of this study was to examine the psychometric properties a new self-concept measure, the Beck Self-Esteem Scale-Short Form (BSES-SF), based on a sample of 204 individuals with schizophrenia or schizoaffective disorder. We evaluated the BSES-SF's dimensionality, internal consistency reliability, and construct and divergent validity using confirmatory factor analysis, Cronbach's alpha, Pearson correlations, independent samples t-tests, and one-way analysis of variance. Findings indicate that the 10-item BSES-SF is a reliable and valid measure of self-concept that is appropriate for a broad group of individuals with schizophrenia spectrum disorders. Following cognitive theory, the scale demonstrated significant relationships with delusion severity, motivation, and depression, further signifying its utility for research and practice efforts that are designed to address psychopathology in schizophrenia.

    The clinician-rated, 16-item Quick Inventory of Depressive Symptomatology (QIDS-C16) has been extensively evaluated in patients with major depressive disorder (MDD). This report assesses the psychometric properties of the QIDS-C16 in outpatients with bipolar disorder (BD, N = 405) and MDD (N = 547) and in bipolar patients in the depressed phase only (BD-D) (N = 99) enrolled in the Texas Medication Algorithm Project (TMAP) using classical test theory (CTT) and the Samejima graded item response theory (IRT) model. Values of coefficient alpha were very similar in BD, MDD, and BD-D groups at baseline (alpha = 0.80-0.81) and at exit (alpha = 0.82-0.85). The QIDS-C16 was unidimensional for all three groups. MDD and BD-D patients (n = 99) had comparable symptom levels. The BD-D patients (n = 99) had the most, and bipolar patients in the manic phase had the least depressive symptoms at baseline. IRT analyses indicated that the QIDS-C16 was most sensitive to the measurement of depression for both MDD patients and for BD-D patients in the average range. The QIDS-C16 is suitable for use with patients with BD and can be used as an outcome measure in trials enrolling both BD and MDD patients. John Wiley & Sons, Ltd

    The Memorial Anxiety Scale for Prostate Cancer (MAX-PC) was developed to identify and assess cancer-specific anxiety among men with prostate cancer (PCa); however, there is no Chinese version. The aim of our study was to translate the English version of MAX-PC into Chinese and evaluate the psychometric properties of it. The study cohort comprised 254 participants. Internal consistency including the Cronbach's alpha coefficient and item-total correlations were used to measure the reliability of the scale. Factor structure was analyzed by exploratory factor analysis and concurrent validity by comparing MAX-PC scores with anxiety subscale scores of the Hospital Anxiety and Depression Scale (HADS). Divergent validity was assessed by correlating MAX-PC with HADS depression subscale, while discriminant ability by comparing differences in MAX-PC scores between different patient groups. The Chinese version of MAX-PC demonstrated good reliability; the Cronbach's alpha coefficient for the total and three subscales (prostate cancer anxiety, PSA anxiety, and fear of recurrence) being 0.94, 0.93, 0.82, and 0.85, respectively. Exploratory factor analysis supported the three-factor structure of the scale established in the original version. Despite the somewhat underperformed divergent validity, the scale demonstrated good concurrent validity with a strong correlation with the HADS anxiety subscale (r = 0.71, p anxiety in Chinese PCa patients.

    Conceptual models for sedimentary rock settings that could be used in future evaluation and suitability studies are being examined through the DOE Repository Technology Program. One area of concern for the hydrologic aspects of these models is discrete fracture flow analysis as related to the estimation of the size of the representative elementary volume, evaluation of the appropriateness of continuum assumptions and estimation of the large-scale permeabilities of sedimentary rocks. A basis for preliminary analysis of flow in fracture systems of the types that might be expected to occur in low permeability sedimentary rocks is presented. The approach used involves numerical modeling of discrete fracture flow for the configuration of a large-scale hydrologic field test directed at estimation of the size of the representative elementary volume and large-scale permeability. Analysis of fracture data on the basis of this configuration is expected to provide a preliminary indication of the scale at which continuum assumptions can be made

    Evaluation recommendations are sometimes included in evaluation reports to highlight specific actions to be taken to improve a program or to make other changes to its operational context. This preliminary study sought to examine evaluation recommendations drawn from 25 evaluation reports published by Canadian federal government departments and agencies, in order to examine the evaluation issues covered and the focus of the recommendations. Our results show that in keeping with policy requirements, the evaluation recommendations focused on program relevance, effectiveness and efficiency and economy. Furthermore, a significant number of recommendations also focused on the implementation of more rigorous performance measurement strategies. The focus of the recommendations did not vary by publication date, recommendation type, and organizational sector. The findings also show that for the most part, the management responses produced as part of the broader evaluation process support the recommendations included in the report and identify specific timelines for implementation.

    To evaluate the implementation of intervention components of the Louisiana Health study, which was a multicomponent childhood obesity prevention program conducted in rural schools. Content analysis. Process evaluation assessed implementation in classrooms, gym classes, and cafeterias. Classroom teachers (n  =  232), physical education teachers (n  =  53), food service managers (n  =  33), and trained observers (n  =  9). Five process evaluation measures were created: Physical Education Questionnaire (PEQ), Intervention Questionnaire (IQ), Food Service Manager Questionnaire (FSMQ), Classroom Observation (CO), and School Nutrition Environment Observation (SNEO). Interrater reliability and internal consistency were assessed on all measures. Analysis of variance and χ(2) were used to compare differences across study groups on questionnaires and observations. The PEQ and one subscale from the FSMQ were eliminated because their reliability coefficients fell below acceptable standards. The subscale internal consistencies for the IQ, FSMQ, CO, and SNEO (all Cronbach α > .60) were acceptable. After the initial 4 months of intervention, there was evidence that the Louisiana Health intervention was being implemented as it was designed. In summary, four process evaluation measures were found to be sufficiently reliable and valid for assessing the delivery of various aspects of a school-based obesity prevention program. These process measures could be modified to evaluate the delivery of other similar school-based interventions.

    Beta-spodumene was investigated as a candidate material for use in fusion reactor environments. Properties which support the use of beta-spodumene include good thermal shock resistance, a very low coefficient of thermal expansion, a low-Z composition which would result in minimum impact on the plasma, and flexibility in fabrication processes. Specimens were irradiated in the Advanced Test Reactor (ATR) to a fluence of 5.3 x 10 22 n/m 2 , E > MeV, and 4.9 x 10 23 n/m 2 thermal fluence in order to obtain a preliminary evaluation of the impact of irradiation on the material. Preliminary data indicate that the mechanical properties of beta-spodumene are little affected by irradiation. Gas production and release have also been investigated. (orig.)

    Brief assessments have the potential to be widely adopted as outcome measures in research but also routine clinical practice. Existing brief rating scales that assess symptoms of schizophrenia or psychosis have a number of limitations including inability to capture five symptom domains of psychosis and a lack of clearly defined operational anchor points for scoring. We developed a new brief rating scale for five symptom domains of psychosis with clearly defined operational anchor points - the Brief Evaluation of Psychosis Symptom Domains (BE-PSD). To examine the psychometric properties of the BE-PSD, fifty patients with schizophrenia or schizoaffective disorder were included in this preliminary cross-sectional study. To test the convergent and discriminant validity of the BE-PSD, correlational analyses were employed using the consensus Positive and Negative Syndrome Scale (PANSS) five-factor model. To examine the inter-rater reliability of the BE-PSD, single measures intraclass correlation coefficients (ICCs) were calculated for 11 patients. The BE-PSD domain scores demonstrated high convergent validity with the corresponding PANSS factor score (rs = 0.81-0.93) as well as good discriminant validity, as evidenced by lower correlations with the other PANSS factors (rs = 0.23-0.62). The BE-PSD also demonstrated excellent inter-rater reliability for each of the domain scores and the total scores (ICC(2,1) = 0.79-0.96). The present preliminary study found the BE-PSD measure to be valid and reliable; however, further studies are needed to establish the psychometric properties of the BE-PSD because of the limitations such as the small sample size and lacking data on test-retest reliability or sensitivity to change.

    The reliability and factor structure of the General Health Questionnaire-12 (GHQ-12) and the Rosenberg Self-Esteem scale (RSE) were evaluated in samples of Hungarian and Slovak early adolescents. The principal component analyses support the two-factor solution for GHQ-12 with subscales "depression/anxiety" and "social dysfunction". Similarly, the RSE appears to be an instrument with a two-factor structure with subscales "negative self-esteem" and "positive self-esteem" in both samples. Reliab...

    This study validated a Chinese adaptation of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CCA), a self-report instrument that evaluates two emotion regulation (ER) strategies, based on the process model of ER. The ERQ-CCA was evaluated using a sample of 1381 Chinese children aged between 7 and 12 years. The internal consistencies of the two factors indicated adequate reliability. Confirmatory factor analysis (CFA) revealed good support as the structure proved to be identical with that of the original instrument. Multigroup CFA supported an invariant factor solution of the ERQ-CCA across several demographic variations (gender, age, registered permanent residence and migrant status) in different groups. Test-retest correlations over a 2-month period were calculated using a subsample of children (N = 70). Convergent validity was evaluated in relation to the model dimensions of the ERQ-CCA, Chinese version of the Children's Depression Inventory, and Chinese version of the Eysenck Personality Questionnaire for Children and Adolescents. Results indicated that the ERQ-CCA has generally satisfactory reliability and validity in investigating the use of two ER strategies during the middle childhood developmental period. © 2015 International Union of Psychological Science.

    Burn as a traumatic life incident manifests severe pain and psychological problems. Specific instruments are needed to evaluate burn patients' psychological issues related to the injury. The aim of this study was to translate and evaluate the reliability and validity of the Persian versions of Impact of Burn Specific Pain Anxiety scale (BSPAS) and Impact of Event Scale (IES). In this cross-sectional study, convenience sampling method was utilized to select 55 Iranian hospitalized burn patients. Combined translation was utilized for translating scales. Alpha cronbach, item-total correlation, convergent and discriminative validity were evaluated. The Cronbach's α for both BSPAS- and IES-Persian version was 0.96. Item-total correlation coefficients ranged from 0.70 to 0.90. Convergent construct validity was confirmed by indicating high correlation between the scales designed to measure the same concepts. The mean score of BSPAS- and IES-Persian version was lower for individuals with a lower TBSA burn percentage which assessed discriminative construct validity of scales. BSPAS- and IES-Persian version showed high internal consistency and good validity for the assessment of burn psychological outcome in hospitalized burn patients. Future studies are needed to determine repeatability, factor structure, sensitivity and specificity of the scales. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    Purpose: In the course of radiotherapy oncological patients often experience considerable psychosocial distress. For its measurement however, no specific questionnaire is available. The stress index radiooncology (SIRO), which is based upon the results of extensive preliminary studies, will be made available as a screening-instrument to facilitate measurement of psychosocial distress of cancer patients, including radiotherapy-induced distress. The aim of this study is, to psychometrically evaluate the preliminary version of the questionnaire, to transfer it to the final version (SIRO) and to gain information about the psychosocial distress of radiooncological patients at the beginning of radiotherapy. Patients and Methods: 104 cancer patients (18 to 85 years) with different diagnoses have been included in the study (Table 1). The data have been assessed by means of the preliminary version of the new questionnaire SIRO, the HADS, EORTC QLQ-C30 and LS. With 25 patients semistructured clinical interviews have been conducted.

    Patients with Parkinson's disease (PD) can show impaired self-awareness of motor deficits (ISAm). We developed a new scale that measures ISAm severity of hyper- and hypokinetic movements in PD during medication on state and defined its psychometric criteria. Included were 104 right-handed, non-depressed, non-demented patients. Concerning ISAm, 38 motor symptoms were assessed using seven tasks, which were performed and self-rated concerning presence of deficit (yes/no) by all patients. The whole procedure was videotaped. Motor symptoms were then evaluated by two independent experts, blinded for patient's ratings, concerning presence, awareness of deficit, and severity. Exploratory principal component analysis (promax rotation) was applied to reduce items. Principal axis factoring was conducted to extract factors. Reliability was examined regarding internal consistency, split-half reliability, and interrater reliability. Validity was verified by applying two additional measures of ISAm. Of the initial 38 symptoms, 15 remained, assessed in five motor tasks and merged to a total severity score. Factor analysis resulted in a four factor solution (dyskinesia, resting tremor right hand, resting tremor left hand, bradykinesia). For all subscales and the total score, measures of reliability (values 0.64-0.89) and validity (effect sizes>0.3) were satisfactory. Descriptive results showed that 66% of patients had signs of ISAm (median 2, range 0-15), with ISAm being most distinct for dyskinesia. We provide the first validation of a test for ISAm in PD. Using this instrument, future studies can further analyze the pathophysiology of ISAm, the psychosocial sequelae, therapeutic strategies and compliance with therapy.

    TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire) is a self-rated instrument that measures five affective temperaments: depressive, cyclothymic, hyperthymic, irritable, and anxious. The aim of our study was to examine the psychometric characteristics of the Slovenian TEMPS-A and to ascertain if temperament profile is related to the professions chosen by Slovenian students. 892 Slovenian university students in six different professional fields (economics, geography, engineering, law, sports pedagogy and nursing) were included in our study. Cronbach's reliability coefficients denoted acceptable internal consistency of the subscales. Principal component analysis revealed relatively good internal structure of the instrument. Nursing and geography students scored the highest on depressive temperament. Sports pedagogues as well as engineers demonstrated the most firm personality structure with distinctive hyperthymic temperament. Law students revealed the most irritable temperament, while nursing and law students scored the highest on anxious temperament. Sample of Slovenian students is not representative for general population. The structure of the sample was crucial as well, as it comprised mainly of younger students who just started their study. The Slovenian version of the TEMPS-A proved to have relatively good internal consistency and internal structure. The questionnaire verified as a reliable and valid instrument and generally in line with previous studies. This study strengthens the perspective that professional areas could be associated with distinct affective temperament profile that could influence career decisions. The findings in students of economics, geography, and sport pedagogy are new as they have not been previously investigated by TEMPS researchers. The results open new possibilities for future research. Copyright © 2012 Elsevier B.V. All rights reserved.

The current study aimed to investigate the psychometric properties of the Danish version of the Theory-of-Mind Storybook Frederik (ToM-Frederik. Methods We assessed whether ToM-Frederik scores differed between a group of 41 typically developing (TD children and a group of 33 children with High functioning Autism Spectrum Disorder (HFASD. A lower mean ToM-Frederik score was expected in the HFASD group. To determine the convergent validity of ToM-Frederik, potential associations with Strange Stories and Animated Triangles (AT were analyzed. Furthermore, potential associations between ToM-Frederik and the Social Responsiveness Scale (SRS and between ToM-Frederik and the Social Emotional Evaluation (SEE Total score were analyzed. Results A significantly higher ToM-Frederik score was observed in the TD group compared to the HFASD group. Furthermore, the convergent validity of ToM-Frederik as a measure of ToM was supported by significant and positive associations with the Strange Stories and the AT scores in the HFASD group, whereas ToM-Frederik was significantly correlated with Strange Stories, but not with AT in the TD group. ToM-Frederik was not significantly associated with SRS in neither the HFASD nor the TD group.Conclusion The findings are supportive of ToM-Frederik as a valid indicator of deficits at the group level in children with HFASD between 7 and 14 years of age. Furthermore, the convergent validity is supported.

    The purpose of the study was to examine the reliability and validity of the Adherence to Refills and Medications Scale-Korean (ARMS-K) among Korean adults with type 2 diabetes. The Korean translated ARMS-K was back-translated to ensure translation equivalency. A cross-sectional survey was used to evaluate the psychometric properties with exploratory factor analysis for validity and Cronbach's alpha coefficients for reliability. The factor analysis of construct validity identified 3 dimensions of the ARMS-K, explaining 54.7% of the total variance. The internal consistency reliability for the total instrument was acceptable with a Cronbach's alpha of .801. There was good correlation between the ARMS-K and 8-item Morisky Medication Adherence Scale-Korean version (r = -0.698), indicating that these scales measure theoretically related constructs as evidence of convergent validity. As evidence of known groups validity, there was a significant association between the ARMS-K score and glycemic control (P = .048), indicating that the good glycemic controlled group was more likely to have a higher rate of adherence to refills and medications than the poor glycemic controlled group. These results support the cross-cultural applicability of the concepts underlying the ARMS-K. The ARMS-K can be used not only to assess adherence to refills and medications in Koreans with diabetes but also to examine the potential role of adherence to refills and medications in enhanced glycemic control of people with diabetes in a variety of clinical settings. © 2016 The Author(s).

    Patients with diabetes and of lower socioeconomic status have difficulty adhering to dietary recommendations. Practical and effective tools assessing self-management behaviors are needed to help evaluate interventions tailored to the needs of individual patients or population groups. This study examined the psychometric properties of a short 11-item version of the Personal Diabetes Questionnaire scale (PDQ-11) using data from the Public-Private Partnership to Improve Diabetes Education trial. Patients (n=411) with type 2 diabetes from ten safety net primary care clinics in the Mid-Cumberland Region of Tennessee completed the PDQ-11, the Summary of Diabetes Self-Care Activities (SDSCA), the Perceived Diabetes Self-Management Scale (PDSMS), and the Adherence to Refills and Medications Scale (ARMS). Statistical analyses were conducted to explore the subscale structure of the PDQ-11, and the internal consistency and validity of its subscales. Exploratory factor analysis of the PDQ-11 revealed four components (Cronbach's α=0.50 to 0.81): Eating Behavior Problems; Use of Information for Dietary Decision Making; Calorie Restriction; and Activity and Exercise. Eating Behavior Problems and Use of Information for Dietary Decision Making had the strongest associations with the diet subscales of the SDSCA and were also correlated with the PDSMS and the ARMS scores (all ps<0.001). Different PDQ-11 subscales were correlated with BMI (Calorie Restriction Activity and Exercise) and blood pressure (Eating Behavior Problems). The PDQ-11 is a useful measure of dietary behaviors in patients with type 2 diabetes; its use may help providers tailor individual nutrition intervention strategies to patients.

    Full Text Available Background: This paper presents design and results from preliminary evaluation of Tangible Geometric Games (TAG-Games for cognitive assessment in young children. The TAG-Games technology employs a set of sensor-integrated cube blocks, called SIG-Blocks, and graphical user interfaces for test administration and real-time performance monitoring. TAG-Games were administered to children from 4 to 8 years of age for evaluating preliminary efficacy of this new technology-based approach.Methods: Five different sets of SIG-Blocks comprised of geometric shapes, segmented human faces, segmented animal faces, emoticons, and colors, were used for three types of TAG-Games, including Assembly, Shape Matching, and Sequence Memory. Computational task difficulty measures were defined for each game and used to generate items with varying difficulty. For preliminary evaluation, TAG-Games were tested on 40 children. To explore the clinical utility of the information assessed by TAG-Games, three subtests of the age-appropriate Wechsler tests (i.e., Block Design, Matrix Reasoning, and Picture Concept were also administered.Results: Internal consistency of TAG-Games was evaluated by the split-half reliability test. Weak to moderate correlations between Assembly and Block Design, Shape Matching and Matrix Reasoning, and Sequence Memory and Picture Concept were found. The computational measure of task complexity for each TAG-Game showed a significant correlation with participants' performance. In addition, age-correlations on TAG-Game scores were found, implying its potential use for assessing children's cognitive skills autonomously.

    The aim of this study was to validate a Persian version of the Cardiac Depression Scale (CDS) in Iranian patients with acute myocardial infarction (AMI). The CDS was forward translated from English into Persian and back-translated to English. Validity was assessed using face, content, and construct validity. Also Cronbach's alpha (α), theta (), and McDonald's omega coefficient were used to evaluate the reliability. Construct validity of the scale showed two factors with eigenvalues greater than one. The Cronbach's α, , McDonald's omega, and construct reliability were greater than .70. The Persian version of the CDS has a two-factor structure (i.e., death anxiety and life satisfaction) and has acceptable reliability and validity. Therefore, the validated instrument can be used in future studies to assess depression in patients with AMI in Iranians.
