    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 acknowledging their 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.

    Introduction: Standardized assessments are widely used by speech pathologists in clinical and research settings to evaluate the language abilities of school-aged children and inform decisions about diagnosis, eligibility for services and intervention. Given the significance of these decisions, it is important that assessments have sound psychometric properties. Objective: The aim of this systematic review was to examine the psychometric quality of currently available comprehensive language assessments for school-aged children and identify assessments with the best evidence for use. Methods: Using the PRISMA framework as a guideline, a search of five databases and a review of websites and textbooks was undertaken to identify language assessments and published material on the reliability and validity of these assessments. The methodological quality of selected studies was evaluated using the COSMIN taxonomy and checklist. Results: Fifteen assessments were evaluated. For most assessments evidence of hypothesis testing (convergent and discriminant validity) was identified; with a smaller number of assessments having some evidence of reliability and content validity. No assessments presented with evidence of structural validity, internal consistency or error measurement. Overall, all assessments were identified as having limitations with regards to evidence of psychometric quality. Conclusions: Further research is required to provide good evidence of psychometric quality for currently available language assessments. Of the assessments evaluated, the Assessment of Literacy and Language, the Clinical Evaluation of Language Fundamentals-5th Edition, the Clinical Evaluation of Language Fundamentals-Preschool: 2nd Edition and the Preschool Language Scales-5th Edition presented with most evidence and are thus recommended for use.

    The underwater sound produced during construction of the Port of Rotterdam harbor extension (Maasvlakte 2) was measured, with emphasis on the contribution of the trailing suction hopper dredgers during their various activities: dredging, transport, and discharge of sediment. Measured source levels of the dredgers, estimated source levels of other shipping, and time-dependent position data from a vessel-tracking system were used as input for a propagation model to generate dynamic sound maps. Various scenarios were studied to assess the risk of possible effects of the sound from dredging activities on marine fauna, specifically on porpoises, seals, and fish.

    A valid and reliable nursing culture assessment tool aimed at capturing general aspects of nursing culture is needed for use in health care settings to assess and then reshape indicated troubled areas of the nursing culture. This article summarizes the Nursing Culture Assessment Tool's (NCAT) development and reports on a cross-sectional, exploratory investigation of its psychometric properties. The research aims were to test the tool's psychometric properties; discover its dimensionality; and refine the item structure to best represent the construct of nursing culture, an occupational subset of organizational culture. Empirical construct validity was tested using a sample of licensed nurses and nursing assistants (n = 340). Exploratory and confirmatory factor analysis (CFA) and logistical regression yielded a 6-factor, 19-item solution. Evidence supports the tool's validity for assessing nursing culture as a basis for shaping the culture into one that supports change, thereby accelerating, improving, and advancing nursing best practices and care outcomes.

    To describe the weaknesses of the current psychometric approach to assessment as a scientific model. The current psychometric model has played a major role in improving the quality of assessment of medical competence. It is becoming increasingly difficult, however, to apply this model to modern assessment methods. The central assumption in the current model is that medical competence can be subdivided into separate measurable stable and generic traits. This assumption has several far-reaching implications. Perhaps the most important is that it requires a numerical and reductionist approach, and that aspects such as fairness, defensibility and credibility are by necessity mainly translated into reliability and construct validity. These approaches are more and more difficult to align with modern assessment approaches such as mini-CEX, 360-degree feedback and portfolios. This paper describes some of the weaknesses of the psychometric model and aims to open a discussion on a conceptually different statistical approach to quality of assessment. We hope that the discussion opened by this paper will lead to the development of a conceptually different statistical approach to quality of assessment. A probabilistic or Bayesian approach would be worth exploring.

    A program of research is needed that assesses the psychometric properties of instruments designed to quantify students' achievement goal orientations to clarify inconsistencies across previous studies and to provide a stronger basis for future research. We conducted traditional psychometric and modern Rasch-model analyses of the Achievement Goals Questionnaire (AGQ, Elliot & McGregor, 2001) and the Patterns of Adaptive Learning Scale (PALS, Midgley et al., 2000) to provide an in-depth analysis of the two most popular instruments in educational psychology. For Study 1, 217 undergraduate students enrolled in educational psychology courses participated. Thirty-four were male and 181 were female (two did not respond). Participants completed the AGQ in the context of their educational psychology class. For Study 2, 126 undergraduate students enrolled in educational psychology courses participated. Thirty were male and 95 were female (one did not respond). Participants completed the PALS in the context of their educational psychology class. Traditional psychometric assessments of the AGQ and PALS replicated previous studies. For both, reliability estimates ranged from good to very good for raw subscale scores and fit for the models of goal orientations were good. Based on traditional psychometrics, the AGQ and PALS are valid and reliable indicators of achievement goals. Rasch analyses revealed that estimates of reliability for items were very good but respondent ability estimates varied from poor to good for both the AGQ and PALS. These findings indicate that items validly and reliably reflect a group's aggregate goal orientation, but using either instrument to characterize an individual's goal orientation is hazardous.

    Recovery is supported by relationships that are characterized by human centeredness, empowerment and a hopeful approach. The Recovery Promoting Relationships Scale (RPRS; Russinova, Rogers, & Ellison, 2006) assesses consumer-provider relationships from the consumer perspective. Here we present the adaptation and psychometric assessment of a Hebrew version of the RPRS. The RPRS was translated to Hebrew (RPRS-Heb) using multiple strategies to assure conceptual soundness. Then 216 mental health consumers were administered the RPRS-Heb as part of a larger project initiative implementing illness management and recovery intervention (IMR) in community settings. Psychometric testing included assessment of the factor structure, reliability, and validity using the Hope Scale, the Working Alliance Inventory, and the Recovery Assessment Scale. The RPRS-Heb factor structure replicated the two factor structures found in the original scale with minor exceptions. Reliability estimates were good: Cronbach's alpha for the total scale was 0.94. An estimate of 0.93 for the Recovery-Promoting Strategies factor, and 0.86 for the Core Relationship. Concurrent validity was confirmed using the Working Alliance Scale (rp = .51, p relationships with Hebrew speaking population.

    Highlights: • A psychometric model to evaluate ‘safety climate’ at nuclear research facilities. • The model presented evidences of good psychometric qualities. • The model was applied to nuclear research facilities in Brazil. • Some ‘safety culture’ weaknesses were detected in the assessed organization. • A potential tool to develop safety management programs in nuclear facilities. - Abstract: A safe and reliable operation of nuclear power plants depends not only on technical performance, but also on the people and on the organization. Organizational factors have been recognized as the main causal mechanisms of accidents by research organizations through USA, Europe and Japan. Deficiencies related with these factors reveal weaknesses in the organization’s safety culture. A significant number of instruments to assess the safety culture based on psychometric models that evaluate safety climate through questionnaires, and which are based on reliability and validity evidences, have been published in health and ‘safety at work’ areas. However, there are few safety culture assessment instruments with these characteristics (reliability and validity) available on nuclear literature. Therefore, this work proposes an instrument to evaluate, with valid and reliable measures, the safety climate of nuclear research facilities. The instrument was developed based on methodological principles applied to research modeling and its psychometric properties were evaluated by a reliability analysis and validation of content, face and construct. The instrument was applied to an important nuclear research organization in Brazil. This organization comprises 4 research reactors and many nuclear laboratories. The survey results made possible a demographic characterization and the identification of some possible safety culture weaknesses and pointing out potential areas to be improved in the assessed organization.

    To develop an instrument for the assessment of safe nursing care (ASNC) within the Iranian context and psychometrically evaluate its reliability and validity. There is a need for a valid and reliable instrument to assess how nurses employ the components of safe nursing care in clinical practice in non-Western countries. This methodological study was conducted in two phases: (1) a qualitative phase of instrument development, and (2) a quantitative phase of psychometric evaluation of the assessment of safe nursing care (ASNC). The instrument's content validity was assessed by experts in the field of safe nursing care. The reliability of this instrument was examined using internal consistency reliability and intra-rater reliability analysis. Exploratory factor analysis was then conducted to establish the instrument's initial construct validity. The instrument developed was a questionnaire with 32 items. The Cronbach's alpha of the scale was 0.92, and Intra-class Correlation Coefficient for intra-rater reliability was 0.78. Exploratory factor analysis resulted in a four-factor solution: (1) evaluation of nursing skills, (2) assessing the patient's psychological needs, (3) assessing the patient's physical need, and (4) Assessing nurses' teamwork. The four factors accounted for 63.54% of the observed variance. The ASNC can be applied to a wide variety of settings because of the broad range of methods utilised to generate items and domains, its comprehensive consideration of the principles of safe care, and its initial reliability and validity. The ASNC can help nurse managers assess whether clinical nurses are prepared to apply their safe care skills in clinical practice. It can also be used by clinical nurses to assess their own and peers' practice to detect potential areas for improvement in nursing care and help nurse managers with planning appropriate quality improvement programmes. © 2016 John Wiley & Sons Ltd.

    2016-11-14

    The psychometric properties of the Learning, Executive, and Attention Functioning (LEAF) scale were investigated in an outpatient clinical pediatric sample. As a part of clinical testing, the LEAF scale, which broadly measures neuropsychological abilities related to executive functioning and learning, was administered to parents of 118 children and adolescents referred for psychological testing at a pediatric psychology clinic; 85 teachers also completed LEAF scales to assess reliability across different raters and settings. Scores on neuropsychological tests of executive functioning and academic achievement were abstracted from charts. Psychometric analyses of the LEAF scale demonstrated satisfactory internal consistency, parent-teacher inter-rater reliability in the small to large effect size range, and test-retest reliability in the large effect size range, similar to values for other executive functioning checklists. Correlations between corresponding subscales on the LEAF and other behavior checklists were large, while most correlations with neuropsychological tests of executive functioning and achievement were significant but in the small to medium range. Results support the utility of the LEAF as a reliable and valid questionnaire-based assessment of delays and disturbances in executive functioning and learning. Applications and advantages of the LEAF and other questionnaire measures of executive functioning in clinical neuropsychology settings are discussed.

    The growing literature relating to job satisfaction among nurses concludes that more research is required to understand the organizational, professional, and personal variables that improve nurse satisfaction and retention. This study developed and psychometrically tested a nurse satisfaction questionnaire, suitable for the nurses' working conditions in Greece. A cross-sectional survey, in Greek, was conducted in three public hospitals. Two-hundred and twenty-five Greek nurses evaluated the psychometric properties of the Greek Nurses' Job Satisfaction Scale (GNJSS). The 18-item questionnaire showed a high degree of internal consistency (Cronbach's alpha = 0.907) and revealed four factors that are consistent with the predetermined subscales and the conceptual base of the GNJSS. The factors, which explain 62.420% of variance, are associated with interaction and recognition, leadership style and organizational policies, self-growth and responsibility, and remuneration and work itself. Although it would be useful to carry out further analyses to assess time-based properties of reliability, the GNJSS questionnaire is a reliable and valid instrument to assess nurses' job satisfaction.

    Full Text Available Introduction: Hyperacusis is defined as a reduction in tolerance to ordinary environmental sounds. Hyperacusis can occur in individuals of all age groups, making daily life difficult for the sufferers. Although there is no objective test to accurately diagnose hyperacusis, questionnaires are useful for the assessment of hyperacusis. The aim of this study was to explore the reduced sound tolerance in university students using a hyperacusis questionnaire (HQ. Materials and Methods: A total of 536 university students (300 females and 236 males aged between 18 and 25 years, with a mean age of 21.34 ± 1.87 years, were assessed using an HQ developed by Khalfa. The mean total score of all the participants was 16.34 ± 7.91, and 5.78% of the participants had total scores indicating hyperacusis, where a majority of them were females. Results: Females had significantly higher scores than men in terms of both the total and the attentional and emotional dimensions. The scores of the participants who reported noise exposure or a decrease in their tolerance to noise were significantly higher than those of the other participants. Even among young adults, there was a group of participants suffering from some problems related to decreased tolerance to everyday sounds. Discussion: Although the Turkish translation of the HQ seems to be a reliable tool for evaluating hyperacusis in young adults, further work with various populations of different age groups is required to establish validity and to assess the psychometric qualities of the Turkish form.

    Yanagihashi, R.; Ohira, Masayoshi; Kimura, Teiji; Fujiwara, Takayuki

    The psycho-physiological effects of several sound stimulations were investigated to evaluate the relationship between a psychological parameter, such as subjective perception, and a physiological parameter, such as the heart rate variability (HRV). Eight female students aged 21-22 years old were tested. Electrocardiogram (ECG) and the movement of the chest-wall for estimating respiratory rate were recorded during three different sound stimulations; (1) music provided by a synthesizer (condition A); (2) birds twitters (condition B); and (3) mechanical sounds (condition C). The percentage power of the low-frequency (LF; 0.05<=0.15 Hz) and high-frequency (HF; 0.15<=0.40 Hz) components in the HRV (LF%, HF%) were assessed by a frequency analysis of time-series data for 5 min obtained from R-R intervals in the ECG. Quantitative assessment of subjective perception was also described by a visual analog scale (VAS). The HF% and VAS value for comfort in C were significantly lower than in either A and/or B. The respiratory rate and VAS value for awakening in C were significantly higher than in A and/or B. There was a significant correlation between the HF% and the value of the VAS, and between the respiratory rate and the value of the VAS. These results indicate that mechanical sounds similar to C inhibit the para-sympathetic nervous system and promote a feeling that is unpleasant but alert, also suggesting that the HRV reflects subjective perception.

    Description, explanation and prediction of changes occurring in old age, which are based on intervention, are outlined as a basic goal in gerontological research. Appropriate psychological assessment techniques are necessary to reach this goal. The Nuremberg Gerontopsychological Inventory (NAI) is introduced as a set of psychological measurements which enable reliable, valid and sensitive evaluation of intervention-induced changes in old age. Four independent assessment levels, i.e. standardized performance tests, observer-ratings, self-ratings and a personality rating are the core components of this inventory. All assessment techniques are adapted for elderly subjects. Standard scores are available for the age range 55-90 years. Interrelations between the applied independent assessment levels are reported and taken to link different aspects of intervention-induced changes. Measuring psychological performance thus gains practical significance, e.g. in terms of activities-of-daily-living. From 14 independent studies the drug sensitivity of the applied measurements is shown. Finally, some recommendations for future psychometrical research are given.

    Researchers and clinicians suggest that excessive tanning may be a behavioral addiction. Given the significance of craving in substance use, craving may be a useful construct to assess in those who tan. We designed this study to assess the psychometric properties of an alcohol craving measure adapted to measure past-week craving to tan. Undergraduate students (n = 421) who reported past-month tanning completed a battery of questionnaires that assessed demographics, tanning-related characteristics, and psychopathology, in addition to the Craving to Tan Questionnaire (CTQ). Analyses provided support for a single factor CTQ with good internal consistency, construct validity and convergent validity. CTQ scores were significantly higher among problematic versus non-problematic and dependent versus non-dependent tanners. CTQ scores were also associated with several tanning-related characteristics, such money spent on tanning in a typical month, frequency of tanning, and frequency of tanning-related problems. Additional analyses found that past-week craving to tan was significantly associated with greater obsessive compulsive and body dysmorphic symptoms. It may be useful in clinical settings to identify those experiencing problems with tanning and in research to further clarify the conceptualization of addiction-like tanning. However, the CTQ needs further evaluation.

    This study evaluated the psychometric properties of the Codependency Assessment Tool (CODAT) developed by C. Hughes Hammer, D. S. Martsolf, and R. A. Zeller (1998a, 1998b) for Turkish students and investigated the relationship of codependency with attachment styles and family problems. After the translation of the CODAT, Beck Depression Inventory, Experiences in Close Relationships-Revised, and Family Problems of Young Adulthood Evaluation Scale, each was administrated to Turkish female nurse students (n = 400). Factor analysis and Cronbach's alpha values were then computed. Five-factor solution revealed a similar factor structure for the Turkish version of CODAT compared with that of the original tool. Five factors explained 48.38% of the variance. All of the items (with one exception) loaded on their original factors. Cronbach's alpha values for factors ranged between .62 and .78. For the total score, Cronbach's alpha was found to be .75. After statistically controlling for the effects of depressive symptoms, analysis of covariance (ANCOVA) was conducted to investigate if the attachment styles and family problems would change depending on codependency levels. For ANCOVAs, CODAT scores were treated at three levels. Students with higher CODAT scores had more attachment-related anxiety and reported more family problems after controlling for the effects of depressive symptoms. Our research results support the internal consistency and validity of the Turkish version of CODAT.

This systematic review was designed to evaluate the standards in pathological video-gaming instrumentation, according to Cicchetti (1994) and Groth-Marnat's (2009) criteria and guidelines for sound psychometric assessment. A total of 63 quantitative studies, including eighteen instruments and representing 58,415 participants, were evaluated. Results indicated that reviewed instrumentation may be broadly characterized as inconsistent. Strengths of available measures include: (i) short length and ease of scoring, (ii) excellent internal consistency and convergent validity, and (iii) potentially adequate data for development of standardized norms for adolescent populations. However, key limitations included: (a) inconsistent coverage of core addiction indicators, (b) varying cut-off scores to indicate clinical status, (c) a lack of a temporal dimension, (d) untested or inconsistent dimensionality, and (e) inadequate data on predictive validity and inter-rater reliability. An emerging consensus suggests that pathological video-gaming is commonly defined by (1) withdrawal, (2) loss of control, and (3) conflict. It is concluded that a unified approach to assessment of pathological video-gaming is needed. A synthesis of extant research efforts by meta-analysis may be difficult in the context of several divergent approaches to assessment. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Darrow, Sabrina M; Callaghan, Glenn C; Bonow, Jordan T; Follette, William C

    2014-04-01

    The evidence based assessment (EBA) movement stresses the importance of psychological measures with strong psychometric properties and clinical utility. The Functional Idiographic Assessment Template system (FIAT; Callaghan, 2006) is a functional analytic behavioral approach to the assessment of interpersonal functioning for use with therapies like Functional Analytic Psychotherapy (FAP; Kohlenberg & Tsai, 1991). While research has begun to demonstrate the clinical utility of the FIAT, its psychometric properties have not been explored. The present study examines the Functional Idiographic Assessment Template-Questionnaire (FIAT-Q), a self-report measure contained in the FIAT. Two different approaches are used to explore the psychometric properties and structure of the FIAT-Q, and test-retest reliability is examined. These methods are discussed along with the use of the FIAT-Q as an alternative to nosological assessment of client behaviors.

  17. Social competence in pediatric brain tumor survivors: evaluating the psychometric properties of assessment tools.

    Science.gov (United States)

    Schulte, Fiona; Barrera, Maru

    2014-02-01

    This study was conducted to identify and describe the instruments that have been used to measure social competence in pediatric brain tumor patients and to summarize the psychometric properties of the most common instruments used to measure social competence in pediatric brain tumor patients. The following psychometric properties were assessed: (a) construct validity; (b) internal consistency reliability; (c) test retest and inter-rater reliability; and (d) responsiveness. Measures were evaluated based on published criteria for psychometric suitability. Ten studies met inclusion criteria for the current review. Based on review of these studies, the Social Skills Rating System (SSRS) yielded the most comprehensive data on psychometric properties. Psychometric properties for the SSRS were considered to be adequate in a pediatric brain tumor population. Specifically, the SSRS meets criteria for construct validity, internal consistency and responsiveness. Other commonly used measures included the CBCL/YSR, the PedsQL4.0 and the Revised Class Play each with sufficient psychometric properties. The SSRS is an appropriate tool to measure social competence in pediatric brain tumor patients. Data for inter-rater reliability and responsiveness in this population is still lacking.

  18. A Psychometric Review of Measures Assessing Discrimination Against Sexual Minorities.

    2016-08-01

    Discrimination against sexual minorities is widespread and has deleterious consequences on victims' psychological and physical wellbeing. However, a review of the psychometric properties of instruments measuring lesbian, gay, and bisexual (LGB) discrimination has not been conducted. The results of this review, which involved evaluating 162 articles, reveal that most have suboptimal psychometric properties. Specifically, myriad scales possess questionable content validity as (1) items are not created in collaboration with sexual minorities; (2) measures possess a small number of items and, thus, may not sufficiently represent the domain of interest; and (3) scales are "adapted" from measures designed to examine race- and gender-based discrimination. Additional limitations include (1) summed scores are computed, often in the absence of scale score reliability metrics; (2) summed scores operate from the questionable assumption that diverse forms of discrimination are necessarily interrelated; (3) the dimensionality of instruments presumed to consist of subscales is seldom tested; (4) tests of criterion-related validity are routinely omitted; and (5) formal tests of measures' construct validity are seldom provided, necessitating that one infer validity based on the results obtained. The absence of "gold standard" measures, the attendant difficulty in formulating a coherent picture of this body of research, and suggestions for psychometric improvements are noted.

    2015-07-01

    Various instruments are used to assess both individual and multiple cancer symptoms. We evaluated the psychometric properties of cancer multisymptom assessment instruments. An Ovid MEDLINE search was done. All searches were limited to adults and in English. All instruments published from 2005 to 2014 (and with at least one validity test) were included. We excluded those who only reported content validity. Instruments were categorized by the three major types of symptom measurement scales employed as follows: visual analogue (VAS), verbal rating (VRS), and numerical rating (NRS) scales. They were then examined in two areas: (1) psychometric thoroughness (number of tests) and (2) psychometric strength of evidence (validity, reliability, generalizability). We also assigned an empirical global psychometric quality score (which combined the concepts of thoroughness and strength of evidence) to rank the instruments. We analyzed 57 instruments (17 original, 40 modifications). They varied in types of scales used, symptom dimensions measured, and time frames evaluated. Of the 57, 10 used VAS, 28 VRS, and 19 NRS. The Edmonton Symptom Assessment System (ESAS), ESAS-Spanish, Hospital Anxiety and Depression Scale (HADS), Profile of Mood States (POMS), Symptom Distress Scale (SDS), M.D. Anderson Symptom Inventory (MDASI)-Russian, and MDASI-Taiwanese were the most comprehensively tested for validity and reliability. The ESAS, ESAS-Spanish, ASDS-2, Memorial Symptom Assessment Scale (MSAS)-SF, POMS, SDS, MDASI (and some translations), and MDASI-Heart Failure all showed good validity and reliability. The MDASI appeared to be the best overall from a psychometric perspective. This was followed by the ESAS, ESAS-Spanish, POMS, SDS, and some MDASI translations. VRS-based instruments were most common. There was a wide range of psychometric rigor in validation. Consequently, meta-analysis was not possible. Most cancer multisymptom assessment instruments need further extensive validation

    2014-02-01

    To examine the usefulness of temporal measures of motor activity during psychometric assessment on two different assessment days, 1 week apart with a scope to help the early identification of hyperactivity. Actigraph measures at the ankle and the waist were compared on the first and the second days of psychometric assessment in a total of 169 children (93 children in ADHD group; 76 children in Non-ADHD group) aged 3 years and 4 years. There was a significant interaction effect between group and time on the activity level at the waist. Although the activity level of the waist in the children with ADHD did not significantly differ between Day 1 and Day 2, the activity level of the children without ADHD declined significantly from Day 1 to 2. A total of 70% of children were correctly classified into ADHD or Non-ADHD groups based only on Day 2 waist activity data. The temporal consistency of hyperactivity in young children with ADHD during psychometric assessment is confirmed, indicating that objective measures of motor activity at the waist over different days of psychometric assessment can provide additional information for the stability of hyperactivity. © 2013 The Authors.

    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.

  12. Assessing the Psychometric Properties of Alternative Items for Certification.

    Science.gov (United States)

    Krogh, Mary Anne; Muckle, Timothy

    Alternative items were added as scored items to the National Certification Examination for Nurse Anesthetists (NCE) in 2010. A common concern related to the new items has been their measurement attributes. This study was undertaken to evaluate the psychometric impact of adding these items to the examination. Candidates had a significantly higher ability estimate in alternative items than in multiple choice questions and 6.7 percent of test candidates performed significantly differently in alternative item formats. The ability estimates of multiple choice questions correlated at r = .58. The alternative items took significantly longer time to answer than standard multiple choice questions and discriminated to a higher degree than MCQs. The alternative items exhibited unidimensionality to the same degree as MCQs and the BIC confirmed the Rasch model as acceptable for scoring. The new item types were found to have acceptable attributes for inclusion in the certification program.

    The Jefferson Scale of Attitude toward Physician-Nurse Collaboration (JSAPNC) has been used to measure the attitude regarding collaboration between nurses and physicians. The aim of this preliminary study was to test the reliability and validity of an Arabic version of the questionnaire and adapt it for use in Palestine. Forward-backward translation of guidelines provided in the literature was followed. Content validity was examined by nine health experts and reliability was assessed with Cronbach's coefficient alpha; test-retest reliability. Construct validity was explored with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) by means of survey among 414 physicians and nurses worked at Shifa Medical Complex in the Gaza Strip in 2015. Response rate was 65% and Cronbach's coefficient alpha was 73.2 for the entire sample. Test-retest reliability was 0.79 measured by Pearson correlation. Factor analysis with Varimax rotation revealed four factors explained 60.5% of the variance in the responses labeled as physician-nurse collaboration, doctor's authority, Shared education and Nursing role in-patient care. Goodness of fit indices from the CFA showed a satisfactory model of fit; Comparative Fit Index (CFI) = 0.89; Root Mean Square Error of Approximation (RMSEA) = 0.06; Standardized Root Mean Square Residual (SRMR) = 0.03; and Hoelter index = 206. The Arabic version of JSAPNC is psychometrically sound tool with satisfactory measurement characteristics including validity and internal consistency reliability. Future research is required to replicate these findings with larger and representative sample. Generalization to Arab speaking countries can be considered but with caution.

    Although assessment of palliative patients' needs is a key issue in palliative care, a suitable instrument for identification of such needs is not available in Central European countries. Our objectives were to produce an adequate tool for identifying the importance and satisfaction of palliative patients' needs and to verify its psychometric properties. The patient needs assessment in palliative care (PNAP) instrument was constructed based on a literature review and qualitative research (focus groups, n = 5). The psychometric properties of the questionnaire were verified by a cross-sectional study. The convergent validity of the questionnaire was determined by confirmatory factor analysis. Furthermore, internal consistency, test-retest reliability, and construct validity were also tested. The qualitative research group comprised 30 participants (27 experts in palliative care, 1 patient, and 2 family members). Psychometric properties were evaluated in a group of 349 hospital inpatients terminally ill with chronic disease or cancer and receiving palliative care. Based on the qualitative data analysis, a questionnaire was constructed that contained 42 items grouped into 5 domains. When testing the psychometric properties of the questionnaire, a new model containing 40 items in 7 domains was produced. Cronbach's α for the entire PNAP questionnaire was 0.89 on the importance scale and 0.80 on the satisfaction scale. Test-retest reliability was higher than 0.7 for all domains in both scales. The results of tests on the psychometric properties of the PNAP questionnaire showed at least satisfactory validity and reliability, and it can be employed to assess the needs of palliative care patients in Central European countries.

  17. Sensitivity and validity of psychometric tests for assessing driving impairment: effects of sleep deprivation.

    Directory of Open Access Journals (Sweden)

    Stefan Jongen

    Full Text Available To assess drug induced driving impairment, initial screening is needed. However, no consensus has been reached about which initial screening tools have to be used. The present study aims to determine the ability of a battery of psychometric tests to detect performance impairing effects of clinically relevant levels of drowsiness as induced by one night of sleep deprivation.Twenty four healthy volunteers participated in a 2-period crossover study in which the highway driving test was conducted twice: once after normal sleep and once after one night of sleep deprivation. The psychometric tests were conducted on 4 occasions: once after normal sleep (at 11 am and three times during a single night of sleep deprivation (at 1 am, 5 am, and 11 am.On-the-road driving performance was significantly impaired after sleep deprivation, as measured by an increase in Standard Deviation of Lateral Position (SDLP of 3.1 cm compared to performance after a normal night of sleep. At 5 am, performance in most psychometric tests showed significant impairment. As expected, largest effect sizes were found on performance in the Psychomotor Vigilance Test (PVT. Large effects sizes were also found in the Divided Attention Test (DAT, the Attention Network Test (ANT, and the test for Useful Field of View (UFOV at 5 and 11 am during sleep deprivation. Effects of sleep deprivation on SDLP correlated significantly with performance changes in the PVT and the DAT, but not with performance changes in the UFOV.From the psychometric tests used in this study, the PVT and DAT seem most promising for initial evaluation of drug impairment based on sensitivity and correlations with driving impairment. Further studies are needed to assess the sensitivity and validity of these psychometric tests after benchmark sedative drug use.

  18. Psychometric Properties of “Community Assessment of Psychic Experiences”: Review and Meta-analyses

    Mark, Winifred; Toulopoulou, Timothea

    2016-01-01

    The Community Assessment of Psychic Experiences (CAPE) has been used extensively as a measurement for psychosis proneness in clinical and research settings. However, no prior review and meta-analysis have comprehensively examined psychometric properties (reliability and validity) of CAPE scores across different studies. To study CAPE’s internal reliability—ie, how well scale items correlate with one another—111 studies were reviewed. Of these, 18 reported unique internal reliability coefficients using data at hand, which were aggregated in a meta-analysis. Furthermore, to confirm the number and nature of factors tapped by CAPE, 17 factor analytic studies were reviewed and subjected to meta-analysis in cases of discrepancy. Results suggested that CAPE scores were psychometrically reliable—ie, scores obtained could be attributed to true score variance. Our review of factor analytic studies supported a 3-factor model for CAPE consisting of “Positive”, “Negative”, and “Depressive” subscales; and a tripartite structure for the Negative dimension consisting of “Social withdrawal”, “Affective flattening”, and “Avolition” subdimensions. Meta-analysis of factor analytic studies of the Positive dimension revealed a tridimensional structure consisting of “Bizarre experiences”, “Delusional ideations”, and “Perceptual anomalies”. Information on reliability and validity of CAPE scores is important for ensuring accurate measurement of the psychosis proneness phenotype, which in turn facilitates early detection and intervention for psychotic disorders. Apart from enhancing the understanding of psychometric properties of CAPE scores, our review revealed questionable reporting practices possibly reflecting insufficient understanding regarding the significance of psychometric properties. We recommend increased focus on psychometrics in psychology programmes and clinical journals. PMID:26150674

    Full Text Available Since about 90% of schools, colleges, and departments of education are currently using portfolios of one form or another as decision-making tools for standards-based decisions regarding certification or licensure (as well as NCATE accreditation, it is appropriate to explore the legal and psychometric aspects of this assessment device. The authors demonstrate that portfolios being used in a high-stakes context are technically testing devices and therefore need to meet psychometric standards of validity, reliability, fairness, and absence of bias. These standards, along with federal law, form the cornerstone for legal challenges to high-stakes decisions when students are denied a diploma or license based on the results of the assessment. The conclusion includes a list of requirements and caveats for using portfolios for graduation and certification decisions in a standards-based environment that help institutions reduce exposure to potential litigation.

    Systematic pain assessment using reliable and valid pain scales is the foundation for optimal pain management in children. To evaluate the available scales for pain assessment in Chinese children, we systematically evaluated the psychometric properties of pain measurements used in Chinese children. We searched Chinese- and English-language databases from their inception to September 2013. Studies were eligible for inclusion if the psychometric properties of pain measures were examined in Chinese children (aged 0-18 years). Two bilingual reviewers independently evaluated the psychometric properties of the identified pain scales by a revised 11-item coding system. In all, 6 studies involving 775 participants were included in this review with six pain scales examined, including the Face, Legs, Activity, Cry, and Consolability (FLACC) Scale, COMFORT-Behavior Scale, Asian Version of Oucher Scale, Pain Observation Scale for Young Children (POCIS), Neonatal Facial Coding System (NFCS) and Pain Assessment Scale for Preterm Infants (PASPI). The FLACC, COMFORT-Behavior Scale, and PASPI had very good psychometric qualities when administered in Chinese children; the Asian Version of Oucher Scale and POCIS showed acceptable to good psychometric qualities; and the NFCS had unacceptable psychometric qualities. Further psychometric testing of these observational measures and self-report pain scales in particular are needed among Chinese children of various age groups and in different pain situations.

    Sprague, R. A.

    1994-02-01

    This document reports efforts on two main goals: to study the short-term ionospheric variability and to study the effects of this variability on high frequency (HF) skywave field strength. To achieve the first goal, ionospheric soundings are being done at 5-minute intervals at San Diego, CA, and at Logan, UT. This time interval was chosen to adequately resolve variations produced by locally generated gravity waves. To study the effects of short-term ionospheric variability on high frequency communications, a circuit is being established to measure the variability of the received HF signal strength. The chosen circuit will have the transmitter located in Forsyth, MT, and the receiver in Imperial Beach, CA (approximately 20 miles south of NRaD).

This study aimed to assess the psychometric properties of a newly developed WSC scale for use in work environments, where bonding social capital is important. We assessed the psychometric properties of a newly developed 6-item scale to measure bonding WSC using two data sources. Participants were 1,650 randomly selected workers who completed an online survey. Exploratory factor analyses were conducted. We examined the item-item and item-total correlations, internal consistency, and associations between scale scores and a previous 8-item measure of WSC. We evaluated test-retest reliability by repeating the survey with 900 of the respondents 2 weeks later. The overall scale reliability was quantified by an intraclass coefficient and the standard error of measurement. We evaluated convergent validity by examining the association with several relevant workplace psychosocial factors using a dataset from workers employed by an electrical components company (n = 2,975). The scale was unidimensional. The item-item and item-total correlations ranged from 0.52 to 0.78 (p psychometric properties.

    There is a need for a psychometrically sound measure of the stigma experienced by diverse persons living with HIV/AIDS (PLHA). The goal of this study was to develop and evaluate a multidimentional measure of internalized HIV stigma that captures stigma related to treatment and other aspects of the disease among sociodemographically diverse PLHA. We developed a 28-item measure of internalized HIV stigma composed of four scales based on previous qualitative work. Internal consistency reliabilit...

    Psychometric instruments are commonly applied in psychotherapeutic research and care for the baseline assessment of symptoms, the planning of therapeutic interventions, the assessment of the longitudinal course of symptoms and outcomes of therapeutic interventions as well as quality management of care. Psychometric properties as well as economic aspects should be considered in the selection of specific instruments. It is assumed that users of psychometric instruments face a great variety of instruments and related information. For that reason, it seems challenging to absorb the current knowledge and to integrate it into clinical practice and research. Thus, it is likely that well-known, established and easily accessible instruments are commonly used, while new developed instruments might not be disseminated in research and healthcare. Based on available international review models, the working group "Psychometrics and Psychodiagnostics" of the German College of Psychosomatic Medicine (DKPM) has developed and tested a review model specifically tailored for psychotherapeutic research and care. The different steps of development, as well as the final review model based on the consensus of the working group are presented. The review model contains 6 generic terms (reliability, validity, objectivity, reference groups and aspects of application) with 21 different criteria to be assessed with 0-3 asterisks (*). The criteria are clearly operationalized and the practical use of the review model is explained and discussed. With the review model for the assessment of psychometric instruments a well-defined evaluation system is made available for research and clinical practice which has been developed by an expert group. The review model facilitates systematic, transparent and comparative evaluation of psychometric instruments along clearly defined criteria. It also supports the selection of psychometric instruments in research and care. Next, the working group aims at

    To establish the psychometric properties of the Family Satisfaction in the Intensive Care Unit 24-item (FS-ICU-24) questionnaire in the United Kingdom. The Family-Reported Experiences Evaluation study recruited family members of patients staying at least 24 hours in 20 participating intensive care units. Questionnaires were evaluated for nonresponse, floor/ceiling effects, redundancy, and construct validity. Internal consistency was evaluated with item-to-own scale correlations and Cronbach α. Confirmatory and exploratory factor analyses were used to explore the underlying structure. Twelve thousand three hundred forty-six family members of 6380 patients were recruited and 7173 (58%) family members of 4615 patients returned a completed questionnaire. One family member per patient was included in the psychometric assessment. Six items had greater than 10% nonresponse; 1 item had a ceiling effect; and 11 items had potential redundancy. Internal consistency was high (Cronbach α, overall .96; satisfaction with care, .94; satisfaction with decision making, .93). The 2-factor solution was not a good fit. Exploratory factor analysis indicated that satisfaction with decision making encompassed 2 constructs-satisfaction with information and satisfaction with the decision-making process. The Family Satisfaction in the Intensive Care Unit 24-item questionnaire demonstrated good psychometric properties in the United Kingdom setting. Construct validity could be improved by use of 3 domains and some scope for further improvement was identified. Copyright © 2016 Elsevier Inc. All rights reserved.

    Decision making is a widespread research topic and plays a crucial role in neuroscience as well as in other research and application fields of, for example, biology, medicine and economics. The most basic implementation of decision making, namely binary discrimination, is successfully interpreted by means of signal detection theory (SDT), a statistical model that is deeply linked to physics. An additional, widespread tool to investigate discrimination ability is the psychometric function, which measures the probability of a given response as a function of the magnitude of a physical quantity underlying the stimulus. However, the link between psychometric functions and binary discrimination experiments is often neglected or misinterpreted. Aim of the present paper is to provide a detailed description of an experimental investigation on a prototypical discrimination task and to discuss the results in terms of SDT. To this purpose, we provide an outline of the theory and describe the implementation of two behavioural experiments in the visual modality: upon the assessment of the so-called psychometric function, we show how to tailor a binary discrimination experiment on performance and decisional bias, and to measure these quantities on a statistical base. Attention is devoted to the evaluation of uncertainties, an aspect which is also often overlooked in the scientific literature.

    Muddled about what makes music? Stuck on the study of harmonics? Dumbfounded by how sound gets around? Now you no longer have to struggle to teach concepts you really don t grasp yourself. Sound takes an intentionally light touch to help out all those adults science teachers, parents wanting to help with homework, home-schoolers seeking necessary scientific background to teach middle school physics with confidence. The book introduces sound waves and uses that model to explain sound-related occurrences. Starting with the basics of what causes sound and how it travels, you'll learn how musical instruments work, how sound waves add and subtract, how the human ear works, and even why you can sound like a Munchkin when you inhale helium. Sound is the fourth book in the award-winning Stop Faking It! Series, published by NSTA Press. Like the other popular volumes, it is written by irreverent educator Bill Robertson, who offers this Sound recommendation: One of the coolest activities is whacking a spinning metal rod...

    In this article we present some of the more important findings from research aimed at the validation and normalisation of the Family Assessment Questionnaire (Dyadic Questionnaire, Family Questionnaire, Self-Estimation Questionnaire), which is the Polish adaptation of Manfred Cierpka's and Gabriele Frevert's "Familienboegen". In the presented study 1511 individuals from 557 families took part. Of these 658 individuals (including 162 children) came from 248 families which had no clinical health or adjustment problems, while 853 individuals (including 305 children) came from 309 families with problems due to schizophrenia, anorexia nervosa, coronary heart disease or family crisis. A new method of analysing raw results from the questionnaire scales was formulated and verified. This method was based on the criterium of sufficient satisfaction regarding the aspect of family life measured by the scale. The original scales of all the questionnaires (Task Completion, Role Performance, Communication, Emotionality, Affective Involvement, Control, and Values and norms) were characterised by average or low reliability; the general scales were characterised by high reliability (the Dyadic Questionnaire with very high reliability). As a result of factor analysis new scales were created with acceptable or high reliability. These were the scale of Positive statements, the scale of Negative statements in the dyadic and family questionnaires, and the scales of kindness, care and resentment in the Self-Estimation Questionnaire. The general scales and the factor scales generally significantly differentiated between the sub-samples selected due to the type of family problems present and relationship. On the other hand the 7 original scales did so only sporadically or weakly. Better results were obtained by families without health or adjustment problems while the worst results were obtained by families in crisis.

    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.

    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.

    No tools to assess women's general sexual and reproductive health needs have been validated in the Iranian context. This study in Sari in Mazandaran province of the Islamic Republic of Iran was conducted to evaluate the psychometric properties of a Persian version of the Sexual and Reproductive Health Needs Assessment Questionnaire (first developed for the International Organization for Migration and United Nations Population Fund). The Persian version of the questionnaire was found to have adequate face and content validity (quantitative and qualitative) for assessing sexual and reproductive health needs among women (content validity index = 0.88). The test-retest reliability showed that, except for the domain of sexually transmitted infections, all domains of the questionnaire had an acceptable reliability (intra-class correlation coefficients > 0.5). This questionnaire is a valid tool for assessing the sexual and reproductive health needs of Iranian women and planning/designing strategies to meet them.

    The APZ questionnaire was developed in order to explore hypotheses on ASCs. First -- in a series of 11 experiments using different induction methods on N = 393 healthy subjects -- the hypothesis was tested that ASCs have major dimensions in common irrespective of the mode of their induction. In the International Study on Altered States of Consciousness (ISASC) the external validity of the experimental results was assessed. The ISASC was carried out on a total of N = 1133 subjects in six countries. The main results of the experimental studies were corroborated in the field studies. The results can be summarized as follows: the common denominator of ASCs is described by three oblique dimensions, designated as "Oceanic Boundlessness (OSE)", "Dread of Ego Dissolution (AIA)" and "Visionary Restructuralization (VUS)". The reliability and validity of the scales are satisfactory. Tested versions of the APZ scales are available in English (UK, USA), German, Italian and Portuguese. Psychometrically as yet untested versions exist in Dutch, Finnish, French, Greek, Spanish and Russian. The APZ questionnaire has become the international standard for the assessment of ASCs, thus helping to integrate research. A psychometrically improved version exists in German (OAV questionnaire). The BETA questionnaire, which measures the dimensions "Vigilance Reduction (VIR)" and "Auditive Alteration (AVE)" is also available in German. These dimensions are most likely etiology-dependent.

    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.

    Patients with schizophrenia tend to have deficits in advanced Theory of Mind (ToM). The "Reading the mind in the eyes" test (RMET), the Faux Pas Task, and the Strange Stories are commonly used for assessing advanced ToM. However, most of the psychometric properties of these 3 measures in patients with schizophrenia are unknown. The aims of this study were to validate the psychometric properties of the 3 advanced ToM measures in patients with schizophrenia, including: (1) test-retest reliability; (2) random measurement error; (3) practice effect; (4) concurrent validity; and (5) ecological validity. We recruited 53 patients with schizophrenia, who completed the 3 measures twice, 4 weeks apart. The Revised Social Functioning Scale-Taiwan short version (R-SFST) was completed within 3 days of first session of assessments. We found that the intraclass correlation coefficients of the RMET, Strange Stories, and Faux Pas Task were 0.24, 0.5, and 0.76. All 3 advanced ToM measures had large random measurement error, trivial to small practice effects, poor concurrent validity, and low ecological validity. We recommend that the scores of the 3 advanced ToM measures be interpreted with caution because these measures may not provide reliable and valid results on patients' advanced ToM abilities.

    Full Text Available Abstract Background Little research has assessed the degree of severity and ordering of different types of sexual behaviors for HIV/STI infection in a measurement scale. The purpose of this study was to apply the Rasch model on psychometric assessment of an HIV/STI sexual risk scale among men who have sex with men (MSM. Methods A cross-sectional study using respondent driven sampling was conducted among 351 MSM in Shenzhen, China. The Rasch model was used to examine the psychometric properties of an HIV/STI sexual risk scale including nine types of sexual behaviors. Results The Rasch analysis of the nine items met the unidimensionality and local independence assumption. Although the person reliability was low at 0.35, the item reliability was high at 0.99. The fit statistics provided acceptable infit and outfit values. Item difficulty invariance analysis showed that the item estimates of the risk behavior items were invariant (within error. Conclusions The findings suggest that the Rasch model can be utilized for measuring the level of sexual risk for HIV/STI infection as a single latent construct and for establishing the relative degree of severity of each type of sexual behavior in HIV/STI transmission and acquisition among MSM. The measurement scale provides a useful measurement tool to inform, design and evaluate behavioral interventions for HIV/STI infection among MSM.

    Psychometric properties of an instrument for assessing cyber-sex addiction. Cyber-sex addiction is a «new pathology» whose prevalence has grown rapidly in recent years. Therefore, it is important to have validated assessment instruments. The aim of this study was the adaptation and validation of the Internet Sex Screening Test (ISST) for its use in a Spanish population. The instrument was administered to 1239 Spanish college students. The results yielded five components that account for 47.5% of the variance. Internal consistency was .88 and temporal stability was .84. Moreover, the instrument had adequate convergent and discriminant validity and was related to other behaviors such as the use of pornography, internet addiction, number of hours online and sexual frequency. Therefore, this tool is proposed as an appropriate measure to assess cyber-sex addiction.

    This study investigated the psychometric properties of the Work/Life Balance Self-Assessment scale among nurse faculty involved in doctoral education. A national random sample of 554 respondents completed the Work/Life Balance Self-Assessment scale, which addresses 3 factors: work interference with personal life (WIPL), personal life interference with work (PLIW), and work/personal life enhancement (WPLE). A principal components analysis with varimax rotation revealed 3 internally consistent aspects of work-life balance, explaining 40.5% of the variance. The Cronbach's alpha coefficients for reliability of the scale were .88 for the total scale and for the subscales, .93 (WIPL), .85 (PLIW), and .69 (WPLE). The Work/Life Balance Self-Assessment scale appears to be a reliable and valid instrument to examine work-life balance among nurse faculty.

    This study examined recognition of Alzheimer's disease symptoms among Korean Americans (KAs) and assessed psychometric properties of the Alzheimer's Disease Symptom Recognition Scale (ADSRS). A cross-sectional survey collected data from 209 KAs, using a self-administered questionnaire. Results show that KAs recognized symptoms related to memory and cognitive functioning well, but had very limited recognition of neuropsychiatric symptoms. Psychometric analysis of ADSRS identified 4 factors in their symptom recognition. Findings suggest a need to raise awareness of Alzheimer's symptoms over the course of the disease. Assessment using ADSRS can be incorporated in communication in the practice context and public outreach.

    To assess the psychometric properties of a Likert-formatted assessment instrument after altering the responses to a dichotomous format. This methodological study used a 15-item instrument to obtain data from 183 participants who responded in both Likert and dichotomous formats. Response sets from each format were compared. Each response set underwent factor analysis, Kuder-Richardson 20, Cronbach's α coefficient, item-total correlation, and parallel form equivalence tests. Factor loads of the instrument varied between .362 and .754 when responses were Likert-formatted and between .370 and .713 when responses were dichotomous. The Cronbach's α coefficient with Likert-formatted responses was .858; the Kuder-Richardson 20 coefficient of the dichotomous responses was .827. Parallel form equivalences were significant at the level of r = .753. The instrument had valid results when either Likert or dichotomous responses were obtained. © 2014 Wiley Periodicals, Inc.

    International behavioral research requires instruments that are not culturally-biased to assess sensation seeking. In this study we described a culturally adapted version of the Brief Sensation Seeking Scale for Chinese (BSSS-C) and its psychometric characteristics. The adapted scale was assessed using an adult sample (n=238) with diverse educational and residential backgrounds. The BSSS-C (Cronbach alpha=0.90) was correlated with the original Brief Sensation Seeking Scale (r = 0.85, p<0.01) and fitted the four-factor model well (CFI=0.98, SRMR=0.03). The scale scores significantly predicted intention to and actual engagement in a number of health risk behaviors, including alcohol consumption, cigarette smoking, and sexual risk behaviors. In conclusion, the BSSS-C has adequate reliability and validity, supporting its utility in China and potential in other developing countries.

    This scale development employed Duval and Wicklund's (1972), Carver's (1979), and Zaborowski's (1987) theories on self-consciousness. The aim of the study was to create a new method to assess the self-consciousness construct, in an effort to operationally express self-consciousness, while circumventing existing metric and other impediments. Initially, 38 pilot interviews were conducted with undergraduate psychology students, and two studies followed, one on 494 participants and one on 248 participants. Exploratory factor analysis models, equivalence testing, followed by a third confirmatory factor analysis study on a separate sample of 216 participants, resulted in a final 24-item scale. A four-factor structure of two public and two private self-consciousness dimensions emerged. The Scale for Self-Consciousness Assessment (SSCA) can be of use in various areas of psychological research, possibly in concurrent use with other constructs of interest, due to its theoretical and research importance and its adequate psychometric properties.

The Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index, and other clinical measures were collected during the clinical trial. We evaluated internal consistency/reliability, construct validity, and responsiveness to change for the SF-36 and FACIT-Fatigue. Results The SF-36 (Cronbach alpha, 0.74-0.92 and FACIT-Fatigue (Cronbach alpha, 0.82-0.86 both had good internal consistency/reliability. At baseline, SF-36 and FACIT-Fatigue scores correlated significantly with Ankylosing Spondylitis Quality of Life scores (r = -0.36 to -0.66 and r = -0.70, respectively; all p Conclusions The SF-36 is a reliable, valid, and responsive measure of health-related quality of life and the FACIT-Fatigue is a brief and psychometrically sound measure of the effects of fatigue on patients with AS. These PROs may be useful in evaluating effectiveness of new treatments for AS. Trial Registration ClinicalTrials.gov: NCT00085644 and NCT00195819

    Full Text Available Background: The objective of this study was to assess psychometric properties of the Polish version of the Meister questionnaire for subjective assessment of work-related mental load among nurses. Material and Methods: A group of 211 nurses (mean age, 43.1±7.26 participated in our study. In the process of adaptation stability (test-retest reliability and factorial validity were assessed. The Maslach Burnout Inventory (MBI was used as a tool for assessing construct validity. Results: Factor analysis of the questionnaire confirmed a very good fit between input data and factor model (Kaiser-Mayer-Olkin measure of 0.83. Selected variables, including overload, monotony, and non-specific load, explained 57%, 41%, and 66% of the variance, respectively. The analysis proved high validity of the tool, Cronbach alpha was 0.83 for the total score. The correlation factor for questions and scores in subscales was high. Repeated measurements resulted in similar outcomes, which proved the stability of this measure. The analysis of construct validity showed that overload, monotony, and non-specific load presented positive correlation with emotional exhaustion and depersonalisation. Correlation between variables was moderate (rHO = 0.39–0.58; p < 0.001. The total score indicated the following correlations: strong positive with emotional exhaustion (rHO = 0.6, p < 0.001, negative with personal achievements, and positive and moderate with depersonalisation (rHO = –0.14; p < 0.05, rHO = 0.48; p < 0.001. Conclusion: The Polish version of the Meister questionnaire meets all psychometric criteria and may be used for evaluating mental load among nurses. Med Pr 2013;64(3:349–358

    Full Text Available Objective To systematically review the scientific literature on the psychometric properties of international instruments for the assessment of autism spectrum disorder (ASD in the Brazilian population. Methods A search of bibliographic references was conducted in six electronic databases: PsycINFO, PubMed, IndexPsi, Lilacs, Capes (theses and dissertations and SciELO. The studies were selected by two independent researchers. Results The procedure identified 11 studies of the Brazilian population that encompassed six ASD assessment tools. Given the information provided, the adaptation of the M-CHAT, a screening instrument, was the best conducted. All steps of the adaptation process were described and the changes made to the final version of the instrument were presented, which was not addressed in other studies. In terms of reliability, all of the instruments that assessed internal consistency showed adequate values. In addition, the ADI-R and the CARS adaptations also satisfactorily contemplated inter-rater reliability and test-retest indices, respectively. Finally, all studies aiming to validate instruments showed evidence of validity and sensitivity, and specificity values above 0.90 were observed in the ASQ, ADI-R and ABC. Conclusion Considering both the psychometric aspects and the copyright information, the screening instrument that currently appears to be best indicated for clinical and research use is the M-CHAT. It was also noticed that there are still no specific ASD diagnostic tools available for use in Brazil. This lack of diagnostic instruments consists in a critical situation for the improvement of clinical practice and the development of research in this area.

    To validate the Sinonasal Outcome Test-16 and Activity Impairment Assessment in patients with acute bacterial sinusitis. Data were used from a phase III clinical trial designed to evaluate the efficacy and safety of moxifloxacin 400 mg once daily for 5 consecutive days in the treatment of acute bacterial sinusitis. The psychometric properties and factor structure of the 2 measures were assessed. Participants were given the measures to self-complete using either a telephone voice response system or a paper-and-pencil format. Three hundred seventy-four patients with acute bacterial sinusitis were used in the analysis. Patients received either a placebo or 400 mg moxifloxacin once daily. Patients were then reviewed at test of cure and follow-up. All analyses were conducted on a combined sample of placebo and active treatment patients. The Sinonasal Outcome Test-16 was associated with minimal missing data at baseline but a higher proportion by test of cure. There was no evidence of floor or ceiling effects and no significant skew. The Activity Impairment Assessment also had low missing data at baseline and no obvious floor or ceiling effects, but the data were not normally distributed. Both measures had good internal consistency. Convergent and divergent validity as well as sensitivity and the minimally important difference are also reported. The measures both have good psychometric properties and are suitable for use with patients with acute bacterial sinusitis. Both instruments are sensitive. The minimal important difference estimates for the Sinonasal Outcome Test-16 are quite high but are similar to estimates reported previously.

    Decentering is defined as the ability to observe one's thoughts and feelings in a detached manner. The Experiences Questionnaire (EQ) is a self-report instrument that originally assessed decentering and rumination. The purpose of this study was to evaluate the psychometric properties of the Spanish version of EQ-Decentering and to explore its clinical usefulness. The 11-item EQ-Decentering subscale was translated into Spanish and psychometric properties were examined in a sample of 921 adult individuals, 231 with psychiatric disorders and 690 without. The subsample of nonpsychiatric participants was also split according to their previous meditative experience (meditative participants, n=341; and nonmeditative participants, n=349). Additionally, differences among these three subgroups were explored to determine clinical validity of the scale. Finally, EQ-Decentering was administered twice in a group of borderline personality disorder, before and after a 10-week mindfulness intervention. Confirmatory factor analysis indicated acceptable model fit, sbχ(2)=243.8836 (p.46; and divergent validity: r<-.35). The scale detected changes in decentering after a 10-session intervention in mindfulness (t=-4.692, p<.00001). Differences among groups were significant (F=134.8, p<.000001), where psychiatric participants showed the lowest scores compared to nonpsychiatric meditative and nonmeditative participants. The Spanish version of the EQ-Decentering is a valid and reliable instrument to assess decentering either in clinical and nonclinical samples. In addition, the findings show that EQ-Decentering seems an adequate outcome instrument to detect changes after mindfulness-based interventions.

    An experimental study was conducted to determine the refraction angle and amplitude changes associated with sound transmission through a circular, open jet shear layer. Both on-axis and off-axis acoustic source locations were used. Source frequency varied from 1 kHz to 10 kHz while freestream Mach number varied from 0.1 to 0.4. The experimental results were compared with an existing refraction theory which was extended to account for off-axis source positions. A simple experiment was also conducted to assess the importance of turbulence scattering between 1 kHz and 25 kHz.

    Organizational readiness for change in healthcare settings is an important factor in successful implementation of new policies, programs, and practices. However, research on the topic is hindered by the absence of a brief, reliable, and valid measure. Until such a measure is developed, we cannot advance scientific knowledge about readiness or provide evidence-based guidance to organizational leaders about how to increase readiness. This article presents results of a psychometric assessment of a new measure called Organizational Readiness for Implementing Change (ORIC), which we developed based on Weiner's theory of organizational readiness for change. We conducted four studies to assess the psychometric properties of ORIC. In study one, we assessed the content adequacy of the new measure using quantitative methods. In study two, we examined the measure's factor structure and reliability in a laboratory simulation. In study three, we assessed the reliability and validity of an organization-level measure of readiness based on aggregated individual-level data from study two. In study four, we conducted a small field study utilizing the same analytic methods as in study three. Content adequacy assessment indicated that the items developed to measure change commitment and change efficacy reflected the theoretical content of these two facets of organizational readiness and distinguished the facets from hypothesized determinants of readiness. Exploratory and confirmatory factor analysis in the lab and field studies revealed two correlated factors, as expected, with good model fit and high item loadings. Reliability analysis in the lab and field studies showed high inter-item consistency for the resulting individual-level scales for change commitment and change efficacy. Inter-rater reliability and inter-rater agreement statistics supported the aggregation of individual level readiness perceptions to the organizational level of analysis.

    Given the relationship between language acquisition and music processing, musical perception (MP) skills have been proposed as a tool for early diagnosis of speech and language difficulties; therefore, a psychometric instrument is needed to assess music perception in children under 10 years of age, a crucial period in neurodevelopment. We created a set of 80 musical stimuli encompassing seven domains of music perception to inform perception of tonal, atonal, and modal stimuli, in a random sample of 1006 children, 6-13 years of age, equally distributed from first to fifth grades, from 14 schools (38% private schools) in So Paulo State. The underlying model was tested using confirmatory factor analysis. A model encompassing seven orthogonal specific domains (contour, loudness, scale, timbre, duration, pitch, and meter) and one general music perception factor, the "m-factor," showed excellent fit indices. The m-factor, previously hypothesized in the literature but never formally tested, explains 93% of the reliable variance in measurement, while only 3.9% of the reliable variance could be attributed to the multidimensionality caused by the specific domains. The 80 items showed no differential item functioning based on sex, age, or enrolment in public vs. private school, demonstrating the important psychometric feature of invariance. Like Charles Spearman's g-factor of intelligence, the m-factor is robust and reliable. It provides a convenient measure of auditory stimulus apprehension that does not rely on verbal information, offering a new opportunity to probe biological and psychological relationships with music perception phenomena and the etiologies of speech and language disorders.

    Full Text Available Background The study of male body image has increased substantially, but there are few assessment tools available for this population. The Male Body Dissatisfaction Scale (MBDS has been widely used among students to research body image disturbances and eating disorders. However, the psychometric properties of this instrument have not been tested in the Brazilian context.Objectives To explore the psychometric properties (convergent validity, internal consistency, test-retest reliability and factor structure of the Brazilian version of the MBDS.Methods Two-hundred sixty-four undergraduate students were evaluated. Pearson’s correlation was used to test the convergent validity of the MBDS and the Drive for Muscularity Scale, the Swansea Muscularity Attitudes Questionnaire, the Rosenberg Self-Esteem Scale, the Beck Depression Inventory, the Eating Attitudes Test-26, and the Commitment to Exercise Scale. Test-retest reliability was evaluated using t-tests for repeated measures and by calculating the coefficient of intraclass correlation. Exploratory factor analysis was conducted, and Cronbach’s α coefficients were determined. A significance level of 5% was adopted.Results The MBDS had an adequate factor structure, with two factors explaining 52.67% of the total variance. It showed excellent internal consistency (Cronbach’s α between 0.90 and 0.92, a high intraclass correlation coefficient (0.81, and convergent validity with the drive for muscularity, the psychological commitment to exercise, low self-esteem, and eating disorder risk behaviour measures.Discussion The MBDS appears to be a valid and reliable tool for evaluating Brazilian male body image dissatisfaction.

    To establish questionnaire scaling and reliability and examine the clinical and psychometric validity of the quality of life assessment based on Traditional Chinese Medicine for advanced gastric cancer (QLASTCM-Ga). The QLASTCM-Ga was developed based on programmed decision procedures with multiple nominal and focus group discussions, in-depth interview, pretesting and quantitative statistical procedures. The questionnaire was administered to 240 patients diagnosed with advanced gastric cancer before and after treatment. Structured group methods were employed to establish a general and a specifific module respectively. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness. The three identified scales of the QLASTCM-Ga and the total score demonstrated good psychometric properties. Test-retest reliability of the total scale and all domains ranged from 0.90 to 0.94, and internal consistency ranged from 0.86 to 0.93. Correlation and factor analysis demonstrated good construct validity. Signifificant difference in the subscales and the total score were found among groups differing in traditional Chinese medicine syndrome, supporting the clinical sensitivity of the QLASTCM-Ga. Statistically signifificant changes were found for each scale and the total score. Responsiveness was also good. The QLASTCM-Ga demonstrates good psychometric and clinical validity to assess quality of life in patients with advanced gastric cancer undergoing traditional Chinese medicine therapy. This study is an important fifirst step for future research in this area.

    Objectives Ambulatory assessment data collection methods are increasingly used to study behavior, experiences, and patient reported outcomes (PROs) such as emotions, cognitions, and symptoms in clinical samples. Data collected close in time at frequent and fixed intervals can assess PROs that are discrete or changing rapidly and provide information about temporal dynamics or mechanisms of change in clinical samples and individuals, but clinical researchers have not yet routinely and systematically investigated the reliability and validity of such measures or their potential added value over conventional measures. The present study provides a comprehensive, systematic evaluation of the psychometrics of several Proximal Intensive Assessment (PIA) measures in a clinical sample and investigates whether PIA appears to assess meaningful differences in phenomena over time. Methods Data was collected on a variety of psychopathology constructs on handheld devices every 4 hours for 7 days from 62 adults recently exposed to traumatic injury of themselves or a family member. Data was also collected on standard self-report measures of the same constructs at the time of enrollment, one week after enrollment, and two months after injury. Results For all measure scores, results showed good internal consistency across items and within persons over time, provided evidence of convergent, divergent, and construct validity, and showed significant between and within-subject variability. Conclusions Results indicate that PIA measures can provide valid measurement of psychopathology in a clinical sample. PIA may be useful to study mechanisms of change in clinical contexts, identify targets for change, and gauge treatment progress. PMID:26567018

    Full Text Available Research on creativity has acquired major development due to its relevance concerning teaching in college. Its assessment is generally conducted by means of verbal and graphic measures. A short scale to measure verbal creativity (CREA in college students from Buenos Aires is currently available. However, right now there are no similar scales designed to assess graphic creativity. In view of that, this study will analyse psychometric features of the ECG scale locally known as Evaluación de la Creatividad Gráfica – Graphic Creativity Assessment, to be employed in the academic milieu in order to provide a complementary measure of verbal creativity. Face and construct validity evidences (converging validity analysis and confirmatory factor analysis were examined as well as reliability, taking into account internal consistency aspects, inter-rater and test-retest stability. The resulting scale showed adequate technical features. The original version, supported by De la Torre’s model, was composed by 12 indicators. This study’s findings maintained 9 of them but, considering new analyses, only 4 of the original ones were retained. This 4-indicator model obtained a better fit to empirical data and good indexes of correlation with a verbal creativity measure, as well as good reliability indicators (internal consistency, inter-rater and test-retest. Findings are discussed taking into account theoretical basis.

    A growing body of literature documents associations of maternal psychosocial stress during pregnancy with fetal, infant and child behaviour and development. However, findings across studies are often inconsistent, which may in part be due to differences in stress definitions and assessments. We systematically reviewed methods applied to assess maternal psychosocial stress during pregnancy in studies looking at associations with biobehavioural outcomes in the offspring. A systematic literature search was performed on Web of Science and PubMed for the time period between January 1999 and October 2009. Psychometric instruments assessing maternal psychosocial stress during pregnancy were identified and described if data on psychometric properties were available. We identified 115 publications that assessed psychosocial stress during pregnancy with validated methods. These publications applied overall 43 different instruments assessing constructs falling under seven categories, ordered according to their frequency of use: anxiety, depression, daily hassles, aspects of psychological symptomatology (not reduced to anxiety or depression), life events, specific socio-environmental stressors and stress related to pregnancy and parenting. If available, we provide information on validity and reliability of the instruments for samples of pregnant women. Within the 'prenatal stress' research, a broad range of instruments is applied to assess psychosocial stress during pregnancy. Prenatal stress research should take into consideration that the variety of methods in use might hamper the comparability of stress research results. In each category of stress constructs, one instrument with good psychometric properties in pregnant women is highlighted as the best currently available measure. © 2013 John Wiley & Sons Ltd.

    The Functional Disability Inventory (FDI; Walker LS, Greene JW. The functional disability inventory: measuring a neglected dimension of child health status. J Pediatr Psychol 1991;16:39-58) assesses activity limitations in children and adolescents with a variety of pediatric conditions. This study evaluated the psychometric properties of the FDI in pediatric pain patients. Participants included 596 patients with chronic abdominal pain, ages 8-17, and a subset of their parents (n = 151) who completed the FDI and measures of pain, limitations in school activities, and somatic and depressive symptoms at a clinic visit. Test-retest reliability was high at 2 weeks (child report, .74; parent-report, .64) and moderate at 3 months (child report, .48; parent report, .39). Internal consistency reliability was excellent, ranging from .86 to .91. Validity was supported by significant correlations of child- and parent-report FDI scores with measures of school-related disability, pain, and somatic symptoms. Study results add to a growing body of empirical literature supporting the reliability and validity of the FDI for functional assessment of pediatric patients with chronic pain.

We developed and piloted four challenging OB Standardized Patient (SP) scenarios in a sample of twenty-one third year OB/GYN clerkship students: Religious Beliefs (RB), Angry Father (AF), Maternal Smoking (MS), and Intimate Partner Violence (IPV). Five trained Standardized Patient Reviewers (SPRs) independently scored twenty-four randomized video-recorded encounters using the OCAT. Cronbach's alpha and Intraclass Correlation Coefficient-2 (ICC-2) were used to estimate internal consistency (IC) and inter-rater reliability (IRR), respectively. Systematic variation in reviewer scoring was assessed using the Stuart-Maxwell test. IC was acceptable to excellent with Cronbach's alpha values (and 95% Confidence Intervals [CI]): RB 0.91 (0.86, 0.95), AF 0.76 (0.62, 0.87), MS 0.91 (0.86, 0.95), and IPV 0.94 (0.91, 0.97). IRR was unacceptable to poor with ICC-2 values: RB 0.46 (0.40, 0.53), AF 0.48 (0.41, 0.54), MS 0.52 (0.45, 0.58), and IPV 0.67 (0.61, 0.72). Stuart-Maxwell analysis indicated systematic differences in reviewer stringency. Our initial characterization of the OCAT demonstrates important issues in communications assessment. We identify scoring inconsistencies due to differences in SPR rigor that require enhanced training to improve assessment reliability. We outline a rational process for initial communication tool validation that may be useful in undergraduate curriculum development, and acknowledge that rigorous validation of OCAT training and implementation is needed to create a valuable OB communication assessment tool.

    ABSTRACT Background: Given the importance of adolescents’ health in establishing health in the newly thriving generation of every society, the first step for adolescents’ health promotion is health needs assessment. The present study was, therefore, conducted to design a valid and reliable scale for health needs assessment of male adolescents. Methods: This is an exploratory sequential mixed method study (2014-2015). The qualitative part was performed using content analysis approach and aimed to generate items pool. Data collection was performed by 7 focus group discussions with 51 male adolescents, and 10 semi-structured in-depth interviews with 10 other adolescents. Nine further in-depth interviews were also performed with 9 key informants. Purposive sampling was used and continued until data saturation. In the quantitative part, the designed scale was psychometrically assessed through the examination of the face and content validities using qualitative and quantitative methods and also the construct validity using the exploratory factor analysis along with the tool’s internal consistency and stability. Results: The content analysis of the data from the qualitative part led to the extraction of 4 main themes and 103 items, which moved to the quantitative stage. The mean content validity index of the scale was estimated 0.91 and content validity ratio was 0.89. The exploratory factor analysis showed 4 factors for the designed scale (49 items), including physical, psychological, social and sexual health needs. The internal consistency and the stability assessment of the scale showed 0.79 and 0.89, respectively. (Phealth needs assessment of male adolescents. PMID:27713893

    The ECFMG Clinical Skills Assessment (CSA) was developed to evaluate whether graduates of international medical schools are ready to enter graduate training programs in the United States. The performance-based patient note exercise is specifically used to assess an examinee's ability to summarize, synthesize and interpret the data collected in a patient interview. The purpose of this study was to investigate whether choice of composition method (typing or writing) affected the psychometric properties of the scores. Using data for a 1-year period, the validity and reliability of typed and written notes was contrasted. Although the characteristics of individuals who chose whether or not to type were different, the statistical analyses indicated that, controlling for examinee ability, physician examiner ratings of the written summaries were not influenced by composition method. The results of this study suggest that the psychometric properties of the patient note scores are invariant with respect to composition method.

    The study of collectivism has implications for HIV prevention research, especially in studies that use a social networking or community mobilization approach. However, research on collectivism in race/ethnicity and sexual minority groups is limited. We psychometrically evaluated a brief version of the Individualism-Collectivism Interpersonal Assessment Inventory (ICIAI) in a chain-referral sample of 400 Latino, 393 Asian/Pacific Islander, and 403 African American men who have sex with men (MSM). Data were collected via a one-time survey on demographics, the ICIAI, acculturation, and ethnicity identity. We conducted a multiple groups confirmatory factor analysis to assess for measurement invariance across the three groups of MSM, as well as tested its reliability and validity. The ICIAI evidenced good psychometric properties and was invariant across all groups. We highlight implications for how this measure of collectivism can be applied toward the study of HIV prevention and in lesbian, gay, bisexual and transgender communities.

    Full Text Available Abstract Aims The purpose of this paper is to summarize the psychometric properties of four short screening scales to assess problematic forms of cannabis use: Severity of Dependence Scale (SDS, Cannabis Use Disorders Identification Test (CUDIT, Cannabis Abuse Screening Test (CAST and Problematic Use of Marijuana (PUM. Methods A systematic computer-based literature search was conducted within the databases of PubMed, PsychINFO and Addiction Abstracts. A total of 12 publications reporting measures of reliability or validity were identified: 8 concerning SDS, 2 concerning CUDIT and one concerning CAST and PUM. Studies spanned adult and adolescent samples from general and specific user populations in a number of countries worldwide. Results All screening scales tended to have moderate to high internal consistency (Cronbach's α ranging from .72 to .92. Test-retest reliability and item total correlation have been reported for SDS with acceptable results. Results of validation studies varied depending on study population and standards used for validity assessment, but generally sensitivity, specificity and predictive power are satisfactory. Standard diagnostic cut-off points that can be generalized to different populations do not exist for any scale. Conclusion Short screening scales to assess dependence and other problems related to the use of cannabis seem to be a time and cost saving opportunity to estimate overall prevalences of cannabis-related negative consequences and to identify at-risk persons prior to using more extensive diagnostic instruments. Nevertheless, further research is needed to assess the performance of the tests in different populations and in comparison to broader criteria of cannabis-related problems other than dependence.

    In this study, we evaluated the psychometric properties of the items to measure the work-family conflict and the time use for personal care and leisure, included in the baseline questionnaire of the Longitudinal Study of Adult Health (ELSA-Brazil). We evaluated temporal stability (7-14 days) using kappa statistic and the validity of the construct by the correlation of Kendall's tau with other variables. Test-retest stability was discreet to moderate and the correlations were compatible with the underlying theory. Future studies in the context of ELSA-Brazil and in other populations will complement the assessment of its relevance. RESUMO Neste estudo, avaliamos as propriedades psicométricas dos itens para mensurar o conflito trabalho-família e o uso do tempo para cuidado pessoal e lazer, incluídos no questionário da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Foram avaliadas a estabilidade temporal (7-14 dias) utilizando estatística kappa e a validade do construto pela correlação tau de Kendall com outras variáveis. A estabilidade teste-reteste foi discreta a moderada e as correlações, compatíveis com a teoria subjacente. Estudos futuros no contexto do ELSA-Brasil e em outras populações complementarão a avaliação da sua pertinência.

    There are indications that motivation correlates with better performance for those studying veterinary medicine. To assess objectively whether motivation profiles influence both veterinary students' attitudes towards educational interventions and their academic success and whether changes in curriculum can affect students' motivation, there is need for an instrument that can provide a valid measurement of the strength of motivation for the study of veterinary medicine. Our objectives were to design and validate a questionnaire that can be used as a psychometric scale to capture the motivation profiles of veterinary students. Question items were obtained from semi-structured interviews with students and from a review of the relevant literature. Each item was scored on a 5-point scale. The preliminary instrument was trialed on a cohort of 450 students. Responses were subjected to reliability and principal component analysis. A 14-item scale was designed, within which two factors explained 53.4% of the variance among the items. The scale had good face, content, and construct validities as well as a good internal consistency (Cronbach's alpha=.88).

    Full Text Available Abstract Background Multiple instruments exist to measure dementia behaviors, but the nursing staff perspective on those behaviors and their level of burden has not been well measured. The goal of this study was to examine the psychometric performance of the Modified Nursing Care Assessment Scale (M-NCAS, a 28-item nurse rating of burden associated with care for institutionalized individuals with dementia. Nurses rate items in terms of extent to which the behavior or characteristic is present ("attitude" domain, and extent to which it is a burden ("strain" domain. Methods Data from 282 patients enrolled in a 12-week, double-blind, randomized clinical trial comparing risperidone treatment to placebo was used to evaluate M-NCAS item performance, internal consistency reliability, and construct validity. Empirical subscales were identified via exploratory factor analysis (EFA. Results Four poorly-performing items were deleted from further analyses. EFA identified 3 "attitude" subscales and 5 "strain" subscales. Cronbach's alphas were 0.65 and above. Correlation with the Cohen-Mansfield Agitation Inventory and the BEHAVE-AD, clinical ratings of dementia behaviors, were low to moderate. Conclusion The M-NCAS provides a valid and reliable means of obtaining care burden ratings from formal caregivers in long-term care, and provides a method for evaluating dementia interventions from the perspective of nursing staff.

    Prior descriptions of the psychometric properties of validated knowledge assessment tools designed to determine Emergency medicine (EM) residents understanding of physiologic and clinical concepts related to mechanical ventilation are lacking. In this setting, we have performed this study to describe the psychometric and performance properties of a novel knowledge assessment tool that measures EM residents' knowledge of topics in mechanical ventilation. Results from a multicenter, prospective, survey study involving 219 EM residents from 8 academic hospitals in northeastern United States were analyzed to quantify reliability, item difficulty, and item discrimination of each of the 9 questions included in the knowledge assessment tool for 3 weeks, beginning in January 2013. The response rate for residents completing the knowledge assessment tool was 68.6% (214 out of 312 EM residents). Reliability was assessed by both Cronbach's alpha coefficient (0.6293) and the Spearman-Brown coefficient (0.6437). Item difficulty ranged from 0.39 to 0.96, with a mean item difficulty of 0.75 for all 9 questions. Uncorrected item discrimination values ranged from 0.111 to 0.556. Corrected item-total correlations were determined by removing the question being assessed from analysis, resulting in a range of item discrimination from 0.139 to 0.498. Reliability, item difficulty and item discrimination were within satisfactory ranges in this study, demonstrating acceptable psychometric properties of this knowledge assessment tool. This assessment indicates that this knowledge assessment tool is sufficiently rigorous for use in future research studies or for assessment of EM residents for evaluative purposes.

    The (hetero)sexual double standard (SDS), prescribing sexual modesty for girls and sexual prowess for boys, negatively affects sexual and mental health. Nevertheless, endorsement and enactment of the SDS is still common. In this study, we respond to recent calls for modernization in the field of sexual double standard research. We describe the development of the "Scale for the Assessment of Sexual Standards among Youth" (SASSY), as well as its psychometric properties. This instrument was designed to measure contemporary sexual double standard endorsement, defined as "the degree to which an individual's attitude reflects a divergent set of expectations for boys and girls, in that boys are expected to be relatively more sexually active, assertive, and knowledgeable and girls are expected to be relatively more sexually reserved, passive, and inexperienced" among adolescents and emerging adults. In Study 1, a pool of 35 items was administered in a Dutch sample (N = 465, 54.8% female, age 16-20). A 20-item set formed a one-dimensional and internally consistent scale and was subsequently administered in a second Dutch sample. Study 2 (N = 818, 58.4% female, age 16-25) again assessed the 20-item set. After dropping one item, the 19-item SASSY proved to be one-dimensional and internally consistent, exhibiting good test-retest reliability, construct validity, and convergent validity. Finally, the instrument showed configural and metric measurement invariance across gender, age, education level, and sexual experience level, and configural, metric, and scalar measurement invariance across time. These studies confirmed the 19-item SASSY to be a reliable and valid new tool for the assessment of contemporary sexual double standard endorsement among adolescents and emerging adults.

    2011-01-01

    Background We evaluated the psychometric characteristics of the Short Form 36 (SF-36) Health Survey and the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue subscale in patients with ankylosing spondylitis (AS). Methods We analyzed clinical and patient-reported outcome (PRO) data collected during 12-week, double-blind, placebo-controlled periods of two randomized controlled trials comparing adalimumab and placebo for the treatment of active AS. The Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index, and other clinical measures were collected during the clinical trial. We evaluated internal consistency/reliability, construct validity, and responsiveness to change for the SF-36 and FACIT-Fatigue. Results The SF-36 (Cronbach alpha, 0.74-0.92) and FACIT-Fatigue (Cronbach alpha, 0.82-0.86) both had good internal consistency/reliability. At baseline, SF-36 and FACIT-Fatigue scores correlated significantly with Ankylosing Spondylitis Quality of Life scores (r = -0.36 to -0.66 and r = -0.70, respectively; all p < 0.0001). SF-36 scores varied by indicators of clinical severity, with greater impairment observed for more severe degrees of clinical activity (all p < 0.0001). FACIT-Fatigue scores correlated significantly with SF-36 scores (r = 0.42 to 0.74; all p < 0.0001) and varied by clinical severity (p < 0.05 to p < 0.0001). Conclusions The SF-36 is a reliable, valid, and responsive measure of health-related quality of life and the FACIT-Fatigue is a brief and psychometrically sound measure of the effects of fatigue on patients with AS. These PROs may be useful in evaluating effectiveness of new treatments for AS. Trial Registration ClinicalTrials.gov: NCT00085644 and NCT00195819 PMID:21600054

    There is a need for a psychometrically sound measure of the stigma experienced by diverse persons living with HIV/AIDS (PLHA). The goal of this study was to develop and evaluate a multidimentional measure of internalized HIV stigma that captures stigma related to treatment and other aspects of the disease among sociodemographically diverse PLHA. We developed a 28-item measure of internalized HIV stigma composed of four scales based on previous qualitative work. Internal consistency reliability estimates in a sample of 202 PLHA was 0.93 for the overall measure, and exceeded 0.85 for three of the four stigma scales. Items discriminated well across scales, and correlations of the scales with shame, social support, and mental health supported construct validity. This measure should prove useful to investigators examining in the role of stigma in HIV treatment and health outcomes, and evaluating interventions designed to mitigate the impacts of stigma on PLHA.

    Lacking in the literature are data addressing the extent to which changes in reproductive and lifestyle factors predispose women in developing nations to higher breast cancer rates, and the degree to which these are due to globalization influences. This article describes the development and psychometric assessment of an instrument intended to measure global, predominantly U.S., influences on breast cancer risk profile among women residing in Mexico. Using investigator consensus and a focus group methodology, the Measure of Globalization Influence on Health Risk (MGIHR) was developed and completed by 341 women. Psychometric analysis support the use of an 11-item Consumerism and Modernity scale and 7-item Reproductive Control and Gender Role scale. The MGIHR is a valid and reliable instrument for understanding changing lifestyle and reproductive factors for breast cancer risk and may provide a more complete understanding of breast cancer development and needed interventions.

    [Purpose] The purpose of this study was to investigate the psychometric properties of the lower extremity subscale of the Fugl-Meyer Assessment lower extremity (FMA-LE) for community-dwelling hemiplegic stroke patients. [Subjects] The participants were 140 community-dwelling hemiplegic stroke patients. [Methods] To determine the psychometric properties of the FMA-LE, we examined construct validity, response characteristics, item discrimination, and internal consistency. [Results] Factor analysis of the FMA-LE revealed that the first factor explained 61.73% of the variance and provided evidence of unidimensionality. The FMA-LE did not show ceiling or floor effects; Cronbach's α was 0.935 (95% CI: 0.919-0.950). [Conclusion] Because the FMA-LE seems to be both valid and reliable, we conclude that it is appropriate for the measurement of the lower extremity motor impairment of community-dwelling hemiplegic stroke patients.

    This paper reports on the psychometric properties of a computerized adaptive test (CAT) version of the Mobility Assessment Tool (MAT) for older adults (MAT-CAT). An item pool of 78 video-animation-based items for mobility was developed, and response data were collected from a sample of 234 participants aged 65-90 years. The video-animation-based instrument was designed to minimize ambiguity in the presentation of task demands. In addition to evaluating traditional psychometric properties including dimensionality, differential item functioning (DIF), and local dependence, we extensively tested the performance of several MAT-CAT measures and compared their performances with a fixed format. Operationally, the MAT-CAT was sufficiently unidimensional and had acceptable levels of local independence. One DIF item was removed. Most importantly, the CAT measures showed that even starting with a single fixed item at the mean ability, the adaptive version delivered better performance than the fixed format in terms of several criteria including the standard error of estimate. The MAT-CAT demonstrated satisfactory psychometric properties and superior performance to a fixed format. The video-animation-based adaptive instrument can be used for assessing mobility with specificity and precision.

    Recent work has raised the potential for Jupiter's decametric radiation to be used as a source for passive radio sounding of its icy moons. Two radar sounding instruments, the Radar for Icy Moon Exploration (RIME) and the Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) have been selected for ESA and NASA missions to Ganymede and Europa. Here, we revisit the projected performance of the passive sounding concept and assess the potential for its implementation as an additional mode for RIME and REASON. We find that the Signal to Noise Ratio (SNR) of passive sounding can approach or exceed that of active sounding in a noisy sub-Jovian environment, but that active sounding achieves a greater SNR in the presence of quiescent noise and outperforms passive sounding in terms of clutter. We also compare the performance of passive sounding at the 9 MHz HF center frequency of RIME and REASON to other frequencies within the Jovian decametric band. We conclude that the addition of a passive sounding mode on RIME or REASON stands to enhance their science return by enabling sub-Jovian HF sounding in the presence of decametric noise, but that there is not a compelling case for implementation at a different frequency.

    People with severe mental disorder have significant difficulties in everyday life that involve the need for continued support. These needs are not easily measurable with the currently available tools. Therefore, a multidimensional scale that assesses the different levels of need for care is proposed, including a study of its psychometric properties. One-hundred and thirty-nine patients (58% men) with a severe mental disorder were assessed using the Required Care Levels for People with Severe Mental Disorder Assessment Scale (ENAR-TMG), the Camberwell Assessment of Need scale, and the Health of the Nation Outcome Scales. ENAR-TMG's psychometric features were examined by: a) evaluating 2 sources of validity evidence (evidence based on internal structure and evidence based on relations to other variables), and b) estimating the internal consistency, temporal stability, inter-rater reliability, and sensitivity to change of scores of the ENAR-TMG's subscales. Exploratory factor analyses revealed a one-factor structure for each of the theoretical dimensions of the scale, in which all but one showed a significant and positive correlation with the Camberwell Assessment of Need (range of r: 0.143-0.557) and Health of the Nation Outcome Scales (range of r: 0.241-0.474) scales. ENAR-TMG subscale scores showed acceptable internal consistency (range of ordinal α coefficients: 0.682-0.804), excellent test-retest (range of intraclass correlation coefficients: 0.889-0.999) and inter-rater reliabilities (range of intraclass correlation coefficients: 0.926-0.972), and satisfactory sensitivity to treatment-related changes (range of η(2): 0.003-0.103). The satisfactory psychometric behaviour of the ENAR-TMG makes the scale a promising tool to assess global functioning in people with a severe mental disorder. Copyright © 2016 SEP y SEPB.

    Full Text Available Abstract Background Rating scales are valuable tools in suicide research and can also be useful supplements to the clinical interview in suicide risk assessments. This study describes the psychometric properties of a Norwegian language version of the Suicide Assessment Scale Self-report version (SUAS-S. Methods Participants were fifty-two patients (mean age = 39.3 years, SD = 10.7 with major depression (53.8%, bipolar disorder (25.0% and/or a personality disorder (63.5% referred to a psychiatric outpatient clinic. The SUAS-S, the screening section of the Beck Scale for Suicidal Ideation (BSS-5, the Beck Depression Inventory (BDI, Beck’s Hopelessness Scale (BHS, the Symptom Check-List-90 R (SCL-90R and the Clinical Global Impression for Severity of Suicidality (CGI-SS were administered. One week later, the patients completed the SUAS-S a second time. Results Cronbach’s alpha for SUAS-S was 0.88 and the test–retest reliability was 0.95 (95% CI: 0.93– 0.97. SUAS-S was positively correlated with the BSS-5 (r = 0.66; 95% CI: 0.47–0.85 for the study sample as a whole and for the suicidal (r = 0.52 and non-suicidal groups (r = 0.50 respectively. There was no difference between the SUAS-S and the BSS-5 in the ability to identify suicidality. This ability was more pronounced when the suicide risk was high. There was a substantial intercorrelation between the score on the SUAS-S and the BDI (0.81 and the BHS (0.76. The sensitivity and specificity of the SUAS-S was explored and an appropriate clinical cut-off value was assessed. Conclusions The study revealed good internal consistency, test–retest reliability and concurrent validity for the Suicide Assessment Scale Self-report version. The discriminatory ability for suicidality was comparable to that of the BSS-5.

    Full Text Available Background: Cognitive abilities assessment, is considered to be one of the most complicated and controversial issues in psychological tests. In spite of great usage of new version of Tehran- Stanford- Binet intelligence scale in screening and diagnosis, they have not made so many endeavors to use this valid test in our country and little researches have been conducted to survey psychometric characteristics of mentioned scale. Given the above considerations, the aim of this study is to investigate Tehran-Stanford-Binet intelligence scale psychometric characteristics in dyslectic children. Materials and Methods: In this psychometric study with classical approach, the statistical society was all the students with dyslexia in the elementary schools of Tehran provinces in 1390. The sample size was equal with 120 students with dyslexia who were selected based on purposive sampling. The new version of Tehran-Stanford-Binet intelligence Scale which includes 10 subtests in verbal and nonverbal domains (fluid reasoning, knowledge, quantitative reasoning, visual spatial processing and working memory and eight IQ was used for them. Findings highlight characteristics of this tool is its ability to calculate the combined scores connected to the reading skills. ROC curve methods, kronbach alpha and pearson correlation was used to analyze the data. Results: Result show that SB5 Test has a good reliability and diagnostic validity. It has 98% sensitivity and a desirable potential to identify student with dyslexia (72%. Conclusion: SB5 could be used as an identificationtoal test for dyslexia.

    Full Text Available Abstract Background Sleep disturbances are a common and bothersome symptom of fibromyalgia (FM. This study reports psychometric properties of a single-item scale to assess sleep quality among individuals with FM. Methods Analyses were based on data from two randomized, double-blind, placebo-controlled trials of pregabalin (studies 1056 and 1077. In a daily diary, patients reported the quality of their sleep on a numeric rating scale ranging from 0 ("best possible sleep" to 10 ("worst possible sleep". Test re-test reliability of the Sleep Quality Scale was evaluated by computing intraclass correlation coefficients. Pearson correlation coefficients were computed between baseline Sleep Quality scores and baseline pain diary and Medical Outcomes Study (MOS Sleep scores. Responsiveness to treatment was evaluated by standardized effect sizes computed as the difference between least squares mean changes in Sleep Quality scores in the pregabalin and placebo groups divided by the standard deviation of Sleep Quality scores across all patients at baseline. Results Studies 1056 and 1077 included 748 and 745 patients, respectively. Most patients were female (study 1056: 94.4%; study 1077: 94.5% and white (study 1056: 90.2%; study 1077: 91.0%. Mean ages were 48.8 years (study 1056 and 50.1 years (study 1077. Test re-test reliability coefficients of the Sleep Quality Scale were 0.91 and 0.90 in the 1056 and 1077 studies, respectively. Pearson correlation coefficients between baseline Sleep Quality scores and baseline pain diary scores were 0.64 (p Conclusion These results provide evidence of the reproducibility, convergent validity, and responsiveness to treatment of the Sleep Quality Scale and provide a foundation for its further use and evaluation in FM patients.

    Early and reliable screening for oropharyngeal dysphagia (OD) symptoms in at-risk populations is important and a crucial first stage in effective OD management. The Eating Assessment Tool (EAT-10) is a commonly utilized screening and outcome measure. To date, studies using classic test theory methodologies report good psychometric properties, but the EAT-10 has not been evaluated using item response theory (e.g., Rasch analysis). The aim of this multisite study was to evaluate the internal consistency and structural validity and conduct a preliminary investigation of the cross-cultural validity of the EAT-10; floor and ceiling effects were also checked. Participants involved 636 patients deemed at risk of OD, from outpatient clinics in Spain, Turkey, Sweden, and Italy. The EAT-10 and videofluoroscopic and/or fiberoptic endoscopic evaluation of swallowing were used to confirm OD diagnosis. Patients with esophageal dysphagia were excluded to ensure a homogenous sample. Rasch analysis was used to investigate person and item fit statistics, response scale, dimensionality of the scale, differential item functioning (DIF), and floor and ceiling effect. The results indicate that the EAT-10 has significant weaknesses in structural validity and internal consistency. There are both item redundancy and lack of easy and difficult items. The thresholds of the rating scale categories were disordered and gender, confirmed OD, and language, and comorbid diagnosis showed DIF on a number of items. DIF analysis of language showed preliminary evidence of problems with cross-cultural validation, and the measure showed a clear floor effect. The authors recommend redevelopment of the EAT-10 using Rasch analysis.

    Full Text Available The anisotropy factor as a function of fiber arrangement, fiber fineness and sample thickness has been derived from the theories of soundwave transformation due to phase changing. The sound absorption coefficient of the anisotropic fibrous material is then theoretically calculated. The fibrous materials were prepared so that the fibers are arranged parallel (perpendicularly laid fiber web called STRUTO technology in the direction of soundwave propagation or perpendicularly (longitudinally laid fiber web to the direction of sound propagation. The sound absorption coefficient was measured due to the Impedance tube. The theoretical results are in good agreement with experimental findings.

    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.

    Xylophone sounds produced by striking wooden bars with a mallet are strongly influenced by the mechanical properties of the wood species chosen by the xylophone maker. In this paper, we address the relationship between the sound quality based on the timbre attribute of impacted wooden bars and the physical parameters characterizing wood species. For this, a methodology is proposed that associates an analysis-synthesis process and a perceptual classification test. Sounds generated by impacting 59 wooden bars of different species but with the same geometry were recorded and classified by a renowned instrument maker. The sounds were further digitally processed and adjusted to the same pitch before being once again classified. The processing is based on a physical model ensuring the main characteristics of the wood are preserved during the sound transformation. Statistical analysis of both classifications showed the influence of the pitch in the xylophone maker judgement and pointed out the importance of two timbre descriptors: the frequency-dependent damping and the spectral bandwidth. These descriptors are linked with physical and anatomical characteristics of wood species, providing new clues in the choice of attractive wood species from a musical point of view.

    Background Currently, terrorism and suicide bombing are global psychosocial processes that attracts a growing number of psychological and psychiatric contributions to enhance practical counter-terrorism measures. The present study is a systematic review that explores the methodological quality reporting and the psychometric soundness of the instruments developed to identify risk factors of terrorism, extremism, radicalisation, authoritarianism and fundamentalism. Method A systematic search strategy was established to identify instruments and studies developed to screen individuals at risk of committing extremist or terrorist offences using 20 different databases across the fields of law, medicine, psychology, sociology and politics. Information extracted was consolidated into two different tables and a 26-item checklist, reporting respectively background information, the psychometric properties of each tool, and the methodological quality markers of these tools. 37 articles met our criteria, which included a total of 4 instruments to be used operationally by professionals, 17 tools developed as research measures, and 9 inventories that have not been generated from a study. Results Just over half of the methodological quality markers required for a transparent methodological description of the instruments were reported. The amount of reported psychological properties was even fewer, with only a third of them available across the different studies. The category presenting the least satisfactory results was that containing the 4 instruments to be used operationally by professionals, which can be explained by the fact that half of them refrained from publishing the major part of their findings and relevant guidelines. Conclusions A great number of flaws have been identified through this systematic review. The authors encourage future researchers to be more thorough, comprehensive and transparent in their methodology. They also recommend the creation of a multi

    This study aimed to validate the Italian version of the Leadership Judgement Indicator, an unconventional instrument devoted to measurement of leaders' judgments and preferred styles, ie, directive, consultative, consensual, or delegative, when dealing with a range of decision-making scenarios. After forward-translation and back-translation, its psychometric properties were estimated for 299 managers at various levels, who were asked to put themselves in the position of leader and to rate the appropriateness of certain ways of responding to challenge. Differences between several groups of managers, ranked in order of seniority, provided evidence for discriminant validity. Internal consistency was adequate. The findings show that the Italian adaptation of the Leadership Judgement Indicator has promising psychometric qualities, suggesting its suitability for use to improve outcomes in both organizational and selection settings.

    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.

    Assessing competencies of students with special educational needs in learning (SEN-L) poses a challenge for large-scale assessments (LSAs). For students with SEN-L, the available competence tests may fail to yield test scores of high psychometric quality, which are-at the same time-measurement invariant to test scores of general education students. We investigated whether we can identify a subgroup of students with SEN-L, for which measurement invariant competence measures of adequate psychometric quality may be obtained with tests available in LSAs. We furthermore investigated whether differences in test-taking behavior may explain dissatisfying psychometric properties and measurement non-invariance of test scores within LSAs. We relied on person fit indices and mixture distribution models to identify students with SEN-L for whom test scores with satisfactory psychometric properties and measurement invariance may be obtained. We also captured differences in test-taking behavior related to guessing and missing responses. As a result we identified a subgroup of students with SEN-L for whom competence scores of adequate psychometric quality that are measurement invariant to those of general education students were obtained. Concerning test taking behavior, there was a small number of students who unsystematically picked response options. Removing these students from the sample slightly improved item fit. Furthermore, two different patterns of missing responses were identified that explain to some extent problems in the assessments of students with SEN-L.

    The SCORE (Systemic Clinical Outcome and Routine Evaluation) is a 40-item questionnaire for completion by family members 12 years and older to assess outcome in systemic therapy. This study aimed to investigate psychometric properties of two short versions of the SCORE and their responsiveness to therapeutic change. Data were collected at 19 centers from 701 families at baseline and from 433 of these 3-5 months later. Results confirmed the three-factor structure (strengths, difficulties, and communication) of the 15- and 28-item versions of the SCORE. Both instruments had good internal consistency and test-retest reliability. They also showed construct and criterion validity, correlating with measures of parent, child, and family adjustment, and discriminating between clinical and nonclinical cases. Total and factor scales of the SCORE-15 and -28 were responsive to change over 3-5 months of therapy. The SCORE-15 and SCORE-28 are brief psychometrically robust family assessment instruments which may be used to evaluate systemic therapy. © 2015 Family Process Institute.

    Full Text Available Background: The CCAENA questionnaire was developed to assess care continuity across levels from the patients’ perspective. The aim is to provide additional evidence on the psychometric properties of the scales of this questionnaire. Methods: Cross-sectional study by means of a survey of a random sample of 1500 patients attended in primary and secondary care in three healthcare areas of the Catalan healthcare system. Data were collected in 2010 using the CCAENA questionnaire. To assess psychometric properties, an exploratory factor analysis was performed (construct validity and the item-rest correlations and Cronbach’s alpha were calculated (internal consistency. Spearman correlation coefficients were calculated (multidimensionality and the ability to discriminate between groups was tested. Results: The factor analysis resulted in 21 items grouped into three factors: patient-primary care provider relationship, patient-secondary care provider relationship and continuity across care levels. Cronbach’s alpha indicated good internal consistency (0.97, 0.93, 0.80 and the correlation coefficients indicated that dimensions can be interpreted as separated scales. Scales discriminated patients according to healthcare area, age and educational level. Conclusion: The CCAENA questionnaire has proved to be a valid and reliable tool for measuring patients’ perceptions of continuity. Providers and researchers could apply the questionnaire to identify areas for healthcare improvement.

    Impairments in social functioning are associated with an array of adverse outcomes. 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. There is a need for ongoing research in the area of the psychometric properties of social skills and behaviours instruments.

    A growing body of research suggests that regularly engaging in stimulating activities across multiple domains-physical, cultural, intellectual, communal, and spiritual-builds resilience. This project investigated the psychometric characteristics of the DeltaQuest Reserve-Building Measure for use in prospective research. The study included Rare Patient Voice panel participants. The web-based survey included the Reserve-Building Measure with one-week re-test, measures of quality of life (QOL) and well-being (PROMIS General Health; NeuroQOL Cognitive Function and Positive Affect & Well-Being short-forms; Ryff Environmental Mastery subscale); and the Big Five Inventory-10 personality measure. Classical test theory and item response theory (IRT) analyses investigated psychometric characteristics of the Reserve-Building Measure. This North American sample (n = 592) included both patients and caregivers [mean age = 44, SD 19)]. Psychometric analyses revealed distinct subscales measuring current reserve-building activities (Active in the World, Games, Outdoors, Creative, Religious/Spiritual, Exercise, Inner Life, Shopping/Cooking, Passive Media Consumption,), past reserve-building activities (Childhood Activities, Achievement), and reserve-related person-factors (Perseverance, Current and Past Social Support, and Work Value). Test-retest stability (n = 101) was moderately high for 11 of 15 subscales (ICC range 0.78-0.99); four were below 0.59 indicating a need for further refinement. IRT analyses supported the item functioning of all subscales. Correlational analyses suggest the measure's subscales tap distinct constructs (range r = 0.11-0.46) which are not redundant with QOL, well-being, or personality (range r = 0.11-0.48). The Reserve-Building Measure provides a measure of activities and person-factors related to reserve that may potentially be useful in prospective research.

    Diarrhea-predominant irritable bowel syndrome (IBS-D) can considerably impact patients' lives. Patient-reported symptoms are crucial in understanding the diagnosis and progression of IBS-D. This study psychometrically evaluates the newly developed IBS-D Daily Symptom Diary and Symptom Event Log (hereafter, "Event Log") according to US regulatory recommendations. A US-based observational field study was conducted to understand cross-sectional psychometric properties of the IBS-D Daily Symptom Diary and Event Log. Analyses included item descriptive statistics, item-to-item correlations, reliability, and construct validity. The IBS-D Daily Symptom Diary and Event Log had no items with excessive missing data. With the exception of two items ("frequency of gas" and "accidents"), moderate to high inter-item correlations were observed among all items of the IBS-D Daily Symptom Diary and Event Log (day 1 range 0.67-0.90). Item scores demonstrated reliability, with the exception of the "frequency of gas" and "accidents" items of the Diary and "incomplete evacuation" item of the Event Log. The pattern of correlations of the IBS-D Daily Symptom Diary and Event Log item scores with generic and disease-specific measures was as expected, moderate for similar constructs and low for dissimilar constructs, supporting construct validity. Known-groups methods showed statistically significant differences and monotonic trends in each of the IBS-D Daily Symptom Diary item scores among groups defined by patients' IBS-D severity ratings ("none"/"mild," "moderate," or "severe"/"very severe"), supporting construct validity. Initial psychometric results support the reliability and validity of the items of the IBS-D Daily Symptom Diary and Event Log.

    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

    Our study objective was to determine the validity and reliability of the breast module of a cancer awareness measure (BCAM) among adult women in western Kenya. The study was conducted between October and November 2012, following three breast cancer screening events. Purposive and systematic random sampling methods were used to identity 48 women for cognitive focus group discussions, and 1061 (594 who attended vs. 467 who did not attend screening events) for surveys, respectively. Face and psychometric validity of the BCAM survey was assessed using cognitive testing, factor analysis of survey data, and correlations. Internal reliability was assessed using Cronbach's alpha. Among survey participants, the overall median age was 34 (IQR: 26-44) years. Compared to those women who did not attend the screening events, women attendees were older (median: 35 vs. 32 years, p = 0.001) more often married (79% vs. 72%, p = 0.006), more educated (52% vs. 46% with more than an elementary level of education, p = 0.001), more unemployed (59% vs. 11%, p = 0.001), more likely to report doing breast self-examination (56% vs. 40%, p = 0.001) and more likely to report having felt a breast lump (16% vs. 7%, p = 0.001). For domain 1 on knowledge of breast cancer symptoms, one factor (three items) with Eigen value of 1.76 emerged for the group that did not attend screening, and 1.50 for the group that attended screening. For both groups two factors (factor 1 "internal influences" and factor 2 "external influences") emerged among domain 4 on barriers to screening, with varied item loadings and Eigen values. There were no statistically significant differences in the factor scores between attendees and non-attendees. There were significant associations between factor scores and other attributes of the surveyed population, including associations with occupation, transportation type, and training for and practice of breast self-examination. Cronbach's alpha showed an

    Eliciting clinicians' views about antipsychotic medication side-effects may assist in understanding strategies that could enhance the identification and management of these side-effects. The present paper details the development and psychometric evaluation of a questionnaire that captures clinicians' perceptions about these issues. An initial item set was derived from a literature review, and then refined by an expert content validity panel that assessed the relevance of the items. The online questionnaire was distributed to Australian mental health nurses and 140 fully completed questionnaires were returned. Principal components analysis yielded two robust scales that conceptually tapped "system responsibility" and "personal confidence". These scales may be used to advance knowledge about how mental health nurses' attitudes towards the assessment and management of antipsychotic medication side-effects influences their clinical behaviour.

    Virtual Reality has been extensively used in a wide range of psychological experiments. In this study, we aimed to introduce NeuroVirtual 3D, a platform that clinicians could use free of charge. The platform we developed relies on NeuroVR software, but we extended it to apply to experiments. The software is available free of charge to researchers and clinical practitioners who can also use a large number of virtual environments and objects already developed. The platform has been developed to connect to virtually every device ever produced by the means of Virtual-Reality Peripheral Network (VRPN) protocols; however, a number of these have already been included and tested in the platform. Among the available devices, the Microsoft Kinect low-cost sensor has already been configured for navigation through the virtual environments and to trigger specific action (sounds, videos, images, and the like) when a specific gesture is recognized, e.g., a step forward or an arm up. A task for neglect and a task for spatial abilities assessment were already implemented within the platform. Moreover, NeuroVirtual 3D integrated a TCP-IP-based module (bridge) to collect the data from virtually any existent biosensor (Thought-Technology, Zephyr and StarStim devices have already been included in the platform). It is able to record any psychophysiological signal during any experiment using also the computed indices in real time. NeuroVirtual 3D is able to record external and internal (e.g., coordinates, keys-press, timestamp) data with a millisecond precision, representing de facto the most advanced technology for experimental psychology using virtual environments available without the needs to program code.

    The burden and severity of student mental health continue to increase in parallel with increasing financial pressures on students and services alike. There is a need for a student-specific measure of distress that acknowledges their unique context. This study examined the feasibility, acceptance, and initial psychometric properties of a US measure, the Counseling Center Assessment of Psychological Symptoms (CCAPS), in a UK student sample. A sample of 294 UK help-seeking students from two universities completed the CCAPS-62 and Clinical Outcomes in Routine Evaluation (CORE-10) as a comparator. The factor solution and reliability of the CCAPS-62 were examined. Correlations and clinical boundaries were determined between the CCAPS-62 subscales and CORE-10, and comparisons were made with US published norms. The CCAPS-62 demonstrated a strong factor solution that matched the intended subscales. All subscales had good reliability and correlated significantly with the CORE-10. The agreement on caseness between the two measures was 92.8% with 86.3% reaching clinical threshold on both the CCAPS-62 and CORE-10. Severity was most noticeable for academic distress, depression, anxiety, and social anxiety. Compared to US data, UK students showed higher clinical severity for all psychological symptoms. The CCAPS-62 is a reliable and psychometrically valid assessment measure to use with UK students without revision. The overall distress indicated is similar to that of the CORE-10, but the individual subscales are more informative of specific student concerns including academic distress, social anxiety, and substance abuse. Potential benefits of administering a student-focused assessment measure in student counselling services are discussed. University students attending counselling in the UK demonstrate clinical severity for academic distress, depression, anxiety, and social anxiety. Compared to university students in the US, UK students present with higher clinical severity on

    2001-12-01

    An instrument to measure the stigma perceived by people with HIV was developed based on the literature on stigma and psychosocial aspects of having HIV. Items surviving two rounds of content review were assembled in a booklet and distributed through HIV-related organizations across the United States. Psychometric analysis was performed on 318 questionnaires returned by people with HIV (19% women, 21% African American, 8% Hispanic). Four factors emerged from exploratory factor analysis: personalized stigma, disclosure concerns, negative self-image, and concern with public attitudes toward people with HIV. Extraction of one higher-order factor provided evidence of a single overall construct. Construct validity also was supported by relationships with related constructs: self-esteem, depression, social support, and social conflict. Coefficient alphas between .90 and .93 for the subscales and .96 for the 40-item instrument provided evidence of internal consistency reliability. The HIV Stigma Scale was reliable and valid with a large, diverse sample of people with HIV.

    Approximately 40% of burn patients develop scar contractures. It is unknown which scar contracture therapy best optimizes activities of daily living (ADL).The appropriateness of self-reported outcome tools in measuring anti-scar contracture therapies has not been assessed. We conducted a systematic review to determine the quality of existing self-reported scales in measuring ADL among burn patients by analyzing and comparing psychometric properties-factor analysis, validity, reliability, and responsiveness. EMBASE, LILACS, American Psychological Association PsycNET databases were searched for relevant articles. Forty-one articles discussing 10 burn and non-burn-specific scales met eligibility criteria of ADL assessment, and available psychometric analyses. A common strength in most scales was good overall reliability. Common weaknesses were insufficient data on factor analyses, content validity specific to ADL assessment, and responsiveness. The psychometric analyses studies on these scales had poor sample variability. There is insufficient data on the dimensionality and responsiveness of existing scales to support their use for measuring ADL in burn patients. Existing scales do not comprehensively measure ADLs as an isolated parameter. A psychometrically valid, comprehensive self-reported burn contracture scale that measures ADLs among a diverse group of burn patients needs to be developed to optimize burn contracture treatments and develop new therapies.

    2009-12-01

    Multi-item multiscale self-report measures are increasingly used in inpatient assessments. When considering a measure for this setting, it is important to evaluate the psychometric properties of the clinical scales and items to ensure that they are functioning as intended in a highly distressed clinical population. The present study examines scale properties for a self-report measure frequently employed in inpatient assessments, the Personality Assessment Inventory (PAI). In addition to examining internal consistency statistics, this study extends prior PAI research by considering key issues related to inpatient assessment (e.g., scale distinctiveness, ceiling effects). Coefficient alphas, interitem correlations, and item- scale relationships suggest that the PAI clinical scales and subscales are internally consistent. Items for respective clinical scales generally showed significantly higher item-scale correlations with their intended scale (as compared with their item-scale correlation with scales they were not intended to measure). In addition, scales' coefficient alpha scores were higher than their interscale correlations. Taken as a whole, these results support the hypothesis that PAI scales were measuring relatively distinct constructs in this inpatient sample. Findings are discussed with regard to the implications for scale interpretation in inpatient assessment, functioning of individual scales and subscales, and functioning of specific items. Limitations of the present study and directions for future research are discussed.

    This paper aims to assess the psychometric properties of the Chinese version of the MASCC Antiemesis Tool (MAT) for measuring chemotherapy-induced nausea and vomiting (CINV). This was a psychometric study using a panel of experts and a prospective observational design. Six experts were invited to identify the content validity and face validity of the MAT, and 115 cancer patients were then recruited from three provincial medical centers in Fuzhou, China. The MAT was self-completed by the patients on the first and the fifth day after receiving the most recent chemotherapy, and patients also rated daily the Index of Nausea, Vomiting, and Retching (INVR) during the first 5 days after chemotherapy. Content validity was measured by the index of the content validity (CVI). Construct validity was estimated by the contrasted groups approach. Concurrent validity was measured by exploring the correlations between the INVR and MAT scores. The reliability of the MAT was examined by Cronbach's alpha and item-to-total correlations. One hundred and eleven subjects returned the completed measures. High content validity was determined. Contrasted groups analysis clearly discriminated the differences on the CINV symptom experiences between different age and gender groups. Excellent concurrent validity was identified, with the Spearman's correlation coefficient between the MAT total score and the INVR overall total score of 0.94 (P < 0.001). Cronbach's alpha for the MAT was 0.73, and the item-to-total correlations ranged from 0.50 to 0.71. The MAT Chinese version is a valid, reliable, and convenient instrument for measuring CINV in Chinese cancer patients.

    Nurses' clinical competence is vital to ensure safe and high quality care, and the continuous assessment of nurses' clinical competence is of major concern. A validated instrument for the self-assessment of nurses' clinical competence at different educational levels across specialties and countries is lacking. The aim of this study was to test the reliability and construct validity of the new Professional Nurse Self-Assessment Scale (ProffNurse SAS) questionnaire in long term and home care contexts in Norway. The questionnaire is based on the Nordic Advanced Practice Nursing model, in which the nurse-patient relationship is central. The study has a cross-sectional survey design. A purposive sample of 357 registered nurses who worked in long term and home care contexts in two geographical regions encompassing eight municipalities and three counties was included. The respondents completed the 74-item ProffNurse SAS questionnaire and demographic background data was collected. Data collection was conducted in two phases: first region autumn 2011 and second region spring 2012. Exploratory factor analyses (EFA) were used to test the psychometric properties of the questionnaire and included the following steps: assessment of the factorality of the data, factor extraction by Principal Component Analysis (PCA), oblimin (oblique) factor rotation, and interpretation. Cronbach's alpha was used to estimate the internal consistency. The PCA revealed a six-component structure, reducing the number of items in the questionnaire from 74 to 51. Based on the content of the highest-loading items, the six components were named: Direct Clinical Practice, Professional Development, Ethical Decision-Making, Clinical Leadership, Cooperation and Consultation, and Critical Thinking. The Cronbach's alpha values ranged from 0.940 (highest; Direct Clinical Practice) to 0.737 (lowest; Critical Thinking), leading to the estimation that the ProffNurse SAS is reliable. The six components support the

    Full Text Available 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

    Full Text Available Abstract Purpose To examine the psychometric properties of the Injection Pen Assessment Questionnaire (IPAQ including the following: 1 item and scale characteristics (e.g., frequencies, item distributions, and factor structure, 2 reliability, and 3 validity. Methods Focus groups and one-on-one dyad interviews guided the development of the IPAQ. The IPAQ was subsequently tested in 136 parent–child dyads in a Phase 3, 2-month, open-label, multicenter trial for a new Genotropin® disposable pen. Factor analysis was performed to inform the development of a scoring algorithm, and reliability and validity of the IPAQ were evaluated using the data from this two months study. Psychometric analyses were conducted separately for each injection pen. Results Confirmatory factor analysis provides evidence supporting a second order factor solution for four subscales and a total IPAQ score. These factor analysis results support the conceptual framework developed from previous qualitative research in patient dyads using the reusable pen. However, the IPAQ subscales did not consistently meet acceptable internal consistency reliability for some group level comparisons. Cronbach’s alphas for the total IPAQ score for both pens were 0.85, exceeding acceptable levels of reliability for group comparisons. Conclusions The total IPAQ score is a useful measure for evaluating ease of use and preference for injection pens in clinical trials among patient dyads receiving hGH. The psychometric properties of the individual subscales, mainly the lower internal consistency reliability of some of the subscales and the predictive validity findings, do not support the use of subscale scores alone as a primary endpoint.

    The gold-standard measure of tic severity in tic disorders (TD), the Yale Global Tic Severity Scale (YGTSS), is a semistructured clinician-administered interview that can be time consuming and requires highly trained interviewers. Moreover, the YGTSS does not provide information regarding frequency and intensity of specific tics because all motor and all vocal tics are rated as a group. The aim of the present study is to describe and test the Adult Tic Questionnaire (ATQ), a measure for the assessment of tic severity in adults, and to report its preliminary psychometric properties. The ATQ is a brief self-report questionnaire that provides information regarding frequency, intensity, and severity of 27 specific tics. In addition, the ATQ produces total frequency, intensity, and severity scores for vocal and motor tics, as well as a global total tic severity score. Results showed that the ATQ demonstrated very good internal consistency and temporal stability. The total, vocal, and motor tic severity scales of the ATQ showed strong correlation with corresponding subscales of the YGTSS, indicating strong convergent validity. Weak correlations with measures of severity of obsessive-compulsive disorder and attention deficit/hyperactivity disorder, indicated strong discriminant validity. The ATQ, a promising measure for the assessment of tic severity in adults with TD, may be a valuable supplement to the current recommended assessment battery for TD. Furthermore, the ATQ enables clinicians and researchers to track changes in the frequency and intensity of specific tics, which is important given their complex and dynamic nature.

    Confrontation therapy proved to be effective in the treatment of fear avoidance beliefs (FAB). Prior to treatment, it is necessary to establish a hierarchy of activities according to their perceived health hazards. For this purpose, we developed the AMIKA scale, which consists of 50 photos showing elderly individuals engaged in daily activities, and investigated its psychometric properties. We conducted a cross-sectional study with repeated measurement after 4 weeks. At the time of both measurements, apart from AMIKA, we assessed pain, disability, FAB, and physical activity. Furthermore, we used ultrasound topometry for the assessment of flexion and extension of the lumbar spine. At t1, a total of 103 elderly individuals with chronic low back pain participated in the study. Their average age was 71.41 years (SD = 5.2). Of these, 67 attended the t2 assessment. Retest reliability amounted to r=0.63 and internal consistency was alpha=0.97. Correlations of the AMIKA scores with pain and disability demonstrated large effect sizes, whereas effect sizes regarding other related FAB scales remained in the medium range. No correlations at all were found with respect to the objective ultrasound measurements and to self-reported physical activity. The results allow the use of AMIKA as an instrument for the generation of a FAB hierarchy in the context of confrontation treatment.

We revised an existing PPCB scale and tested its psychometric properties for HIV patients in Kenya. Methods. 17 items (five-point scale measuring PPCB were initially adopted from the Matched Pair Instrument (MPI. Between July and August 2011, we surveyed a convenient sample of 400 HIV adult patients, attending three Academic Model Providing Healthcare program (AMPATH clinics in Eldoret, Kenya. Of these 400, eight also participated in cognitive interviews, and 200 were invited to return after one week for follow-up interviews; 134 (67% returned and were interviewed. Construct and content validity were established using an exploratory factor analysis, bivariate analyses, internal consistency, test-retest reliability and cognitive interviews. Results. Construct and content validity supported a one-dimensional measure of 13 PPCB items. Items assessed physicians’ effort to promote a favorable atmosphere for interaction with HIV patients. Biases associated with encoding and comprehension of specific terms, such as “discussion, involvement or concerns,” were noted. Internal consistency (Cronbach’s alpha = .81 and one-week retest reliability scores (.82 supported the reliability of the 13-item scale. Discussion. The revised PPCB scale showed acceptable validity and reliability in Kenya.

    The Emotion Understanding Assessment (EUA) is based on a theoretical model of recognizing emotion expressions and reasoning about situation-based, desire-based, and belief-based emotions. While research has noted that emotion understanding predicts current and future social and academic functioning, little is known about the psychometric properties of the EUA. This research sought to test the EUA factor structure and measurement invariance across gender, across language (English and Spanish speakers), and over time (24 weeks) in 281 preschoolers attending Head Start. Results indicated that a two-factor model of emotion expression recognition and emotional perspective taking of the EUA fit the data for the total sample, for each group (gender and language), and at each time point. Furthermore, configural and scalar invariance of the EUA was demonstrated across gender, language, and time. These results offer support that the EUA is assessing emotion expression recognition and emotional perspective taking constructs equivalently in boy, girls, Spanish and English speakers, and over time. Examination of latent means across groups and time indicate no differences in emotion understanding based on gender or language or over the 24-week time frame in this sample of preschoolers attending Head Start.

    2005-02-01

    This study examined the psychometric properties of performance measures for three novel, interactive virtual reality vignette exercises developed to assess social competency skills of at-risk adolescents. Performance data were collected from 117 African-American male 15-17 year olds. Data for 18 performance measures were obtained, based on adolescents' interaction with a provocative virtual teenage character. Twelve of the 18 performance measures loaded on two factors corresponding to emotional control and interpersonal communication skills, providing support for their factorial validity. The internal reliability coefficients for the two multi-item measures were 0.88 and 0.91, respectively. Additional analyses with established measures of three psychosocial factors (beliefs supporting aggression, aggressive conflict-resolution style and hostility) and behavioral criteria (e.g., self-reported behavioral misconduct and drug use) provided limited support for the construct and criterion-related validity of the performance measures. Study findings suggest that the virtual reality vignette exercises may represent a promising approach for assessing adolescents' social competency skills.

    This study describes the psychometric properties of the Inventory of Motivations for Suicide Attempts (IMSA). The IMSA was designed to comprehensively assess motivations for suicide emphasized by major theories of suicidality. The IMSA was administered to two samples of recent suicide attempters, undergraduates (n = 66) and outpatients (n = 53). The IMSA exhibited a reliable two-factor structure in which one factor represented Intrapersonal motivations related to ending emotional pain, and the second represented Interpersonal motivations related to communication or help-seeking. Convergent validity and divergent validity of IMSA scales were supported by expected patterns of correlations with another measure of suicide motivations. In addition, the IMSA scales displayed clinical utility, in which greater endorsement of intrapersonal motivations was associated with greater intent to die, whereas greater endorsement of interpersonal motivations was associated with less lethal intent and greater likelihood of rescue. Findings suggest the IMSA can be of use for both research and clinical purposes when a comprehensive assessment of suicide motivations is desired.

    A comprehensive questionnaire designed to assess the full spectrum of potential human papillomavirus (HPV)-related psychosocial effects in women does not exist. The HPV Impact Profile (HIP) was developed to determine the psychosocial impact of HPV infection and related interventions. Draft instrument items and domains were developed using a literature review and cognitive debriefing interviews with women who had experienced HPV-related conditions. An importance rating questionnaire guided item ranking and reduction. A draft questionnaire was pilot-tested for comprehension and ease of completion. Psychometric evaluation of the final HIP was conducted in a survey of 583 women. Data quality, item acceptability, scale acceptability, reliability, and discriminate construct validity were assessed. The final HIP contained 29 items rated on a 0-10 point discretized visual analog scales grouped into seven hypothesized domains. Total HIP scores ranged from 0 (no impact) to 100 (worst impact). Data quality was high, with missing data for items ranging from 0 to 0.7% and over 99% of the scores were computable. Cronbach's alpha ranged from 0.64 to 0.90 and was > or =0.7 for 5/7 domains. Discriminant construct validity was demonstrated. Appropriate modifications could potentially be made to improve some aspects of the HIP, including modification to include other HPV diseases such as head and neck, anal, and vulvovaginal cancers and HPV disease in men. The disease-specific HIP has favorable reliability and construct validity and a good ability to discriminate among disease severity.

    A multi-beam system transmits sound waves and receives the round-trip time of their reflection or scattering, and thus it is possible to determine the depth and coordinates of the detected targets using the sound velocity profile (SVP) based on Snell's Law. The SVP is determined by a device. Because of the high sampling rate of the modern device, the operational time of ray tracing and beam footprint reduction will increase, lowering the overall efficiency. To promote the timeliness of multi-beam surveys and data processing, redundant points in the original SVP must be screened out and at the same time, errors following the streamlining of the SVP must be evaluated and controlled. We presents a new streamlining and evaluation method based on the Maximum Offset of sound Velocity (MOV) algorithm. Based on measured SVP data, this method selects sound velocity data points by calculating the maximum distance to the sound-velocity-dimension based on an improved Douglas-Peucker Algorithm to streamline the SVP (Fig. 1). To evaluate whether the streamlined SVP meets the desired accuracy requirements, this method is divided into two parts: SVP streamlining, and an accuracy analysis of the multi-beam sounding data processing using the streamlined SVP. Therefore, the method is divided into two modules: the streamlining module and the evaluation module (Fig. 2). The streamlining module is used for streamlining the SVP. Its core is the MOV algorithm.To assess the accuracy of the streamlined SVP, we uses ray tracing and the percentage error analysis method to evaluate the accuracy of the sounding data both before and after streamlining the SVP (Fig. 3). By automatically optimizing the threshold, the reduction rate of sound velocity profile data can reach over 90% and the standard deviation percentage error of sounding data can be controlled to within 0.1% (Fig. 4). The optimized sound velocity profile data improved the operational efficiency of the multi-beam survey and data post

    Background and aims The surge of problematic Internet use in adolescents is a continuously growing problem across the globe. To our knowledge, to date valid questionnaire-based measurement of problematic Internet use is possible only by self-assessment. The objective for the present study was to adapt an established instrument for a parental assessment of adolescent problematic Internet use and to evaluate the psychometric properties of this questionnaire. Methods Data were collected from a representative German sample of 1,000 parents of adolescents aged between 12 and 17 years using a standardized questionnaire. To assess problematic Internet use, we adapted the established Young Diagnostic Questionnaire by rewording the items to survey a parental rating instead of a self-report ("Parental version of the Young Diagnostic Questionnaire," PYDQ). Additionally, we assessed the Internet usage time, parental monitoring, family functioning, school performance of the adolescent, and parent-adolescent conflicts. We conducted a confirmatory factor analysis based on the 8 items of the PYDQ modeled as categorical indicators and one latent factor using a robust weighted least squares estimator. We also calculated a reliability coefficient, the acceptance of the instrument, and performed correlation analyses. Results The unidimensional model showed excellent global goodness-of-fit (χ(2)/df = 1.65, RMSEA = 0.03, CFI = 0.99, TLI = 0.99) and satisfactory factor loadings (standardized values ranged from 0.60 to 0.77). We observed a reliability coefficient of 0.70, a good acceptance of the instrument, and the correlation analyses indicated the construct validity of the PYDQ. Discussion and conclusion The proposed PYDQ is a suitable instrument for parental assessment of adolescent problematic Internet use.

    Full Text Available Negative affect (NA plays a significant role in the initiation, persistence, and response to psychotherapy of many client problems (Moses & Barlow, 2006. This report describes the development of a brief NA measure, the Depression/Anxiety Negative Affect (DANA scale, and preliminary analyses of its psychometric properties. An initial pool of DANA items was selected on the basis of a review of relevant literature about emotion science and counseling outcomes, related tests, and feedback from psychotherapists as part of a pilot test. The DANA was evaluated in two representative clinical samples where psychotherapists produced a total of 363 session ratings with 81 clients. DANA scores evidenced adequate internal consistency, evidence of convergent and discriminant validity, and sensitivity to change over the course of psychotherapy. Effect sizes (ES of DANA scores consistently equaled or exceeded the average ES of .68 found for scales assessing the outcomes of counseling and psychotherapy in meta-analytic studies (Smith & Glass, 1977. ESs greater than 1 were found on DANA variables for clients whose therapists rated them as experiencing, rather than avoiding, NA.

    OBJECTIVE Cervical spondylotic myelopathy (CSM) is the most common cause of nontraumatic spinal cord impairment and disability in the world. Given that the Japanese Orthopaedic Association (JOA) score is the most frequently used outcome measure in clinical research and practice for treating patients with CSM, this review was undertaken to comprehensively and critically evaluate the psychometric properties of the JOA score. METHODS The authors identified studies (published in the period of January 1975 to November 2015) on the psychometric properties of the original, revised, and modified versions of the JOA score in Medline, PsycINFO, Excerpta Medica dataBASE (EMBASE), American College of Physicians Journal Club, and Cochrane Database of Systematic Reviews. Additional publications were captured in a secondary search of the bibliographies in both original research articles and literature reviews identified in the original search. The JOA scores were evaluated for item generation and reduction, internal consistency, reliability, validity, and responsiveness. This review included all those versions of the JOA score whose psychometric properties had been reported in at least 2 published studies. RESULTS The primary search strategy identified 59 studies, of which 9 fulfilled the inclusion and exclusion criteria. An additional 18 publications were captured in the secondary search and included in the analysis. The key findings from the 27 studies analyzed indicated the following: 1) the original JOA score (1975) was the source for the revised JOA score (1994) and 3 modified versions (1991, 1993, and 1999 JOA scores) reported or used in at least 2 published studies; 2) the revised and modified versions of the JOA score are markedly different from each other; 3) only the revised JOA score (1994) was validated with the original JOA score; and 4) the 1975 JOA score is the most appropriate instrument for assessing patients in Asian populations (especially from Japan) because

    Diagnostic ultrasound imaging has been a common tool in medical practice for several decades. It provides a safe and effective method for imaging structures internal to the body. There has been a recent increase in the use of ultrasound technology to visualize the shape and movements of the tongue during speech, both in typical speakers and in clinical populations. Ultrasound imaging of speech has greatly expanded our understanding of how sounds articulated with the tongue (lingual sounds) are produced. Such information can be particularly valuable for speech-language pathologists. Among other advantages, ultrasound images can be used during speech therapy to provide (1) illustrative models of typical (i.e. "correct") tongue configurations for speech sounds, and (2) a source of insight into the articulatory nature of deviant productions. The images can also be used as an additional source of feedback for clinical populations learning to distinguish their better productions from their incorrect productions, en route to establishing more effective articulatory habits. Ultrasound feedback is increasingly used by scientists and clinicians as both the expertise of the users increases and as the expense of the equipment declines. In this tutorial, procedures are presented for collecting ultrasound images of the tongue in a clinical context. We illustrate these procedures in an extended example featuring one common error sound, American English /r/. Images of correct and distorted /r/ are used to demonstrate (1) how to interpret ultrasound images, (2) how to assess tongue shape during production of speech sounds, (3), how to categorize tongue shape errors, and (4), how to provide visual feedback to elicit a more appropriate and functional tongue shape. We present a sample protocol for using real-time ultrasound images of the tongue for visual feedback to remediate speech sound errors. Additionally, example data are shown to illustrate outcomes with the procedure.

    Technology increasingly influences the everyday lives of most people, and the ability to manage technology can be seen as a prerequisite for participation in everyday occupations. However, knowledge of the ability and skills required for management of technology is sparse. This study aimed to validate a new observation-based assessment, the Management of Everyday Technology Assessment (META). The META has been developed to assess the ability to manage technology in everyday life. A sample of 116 older adults with and without cognitive impairment were observed and interviewed by the use of the META when managing their everyday technology at home. The results indicate that the META demonstrates acceptable person response validity and technology goodness-of-fit. Additionally, the META can separate individuals with higher ability from individuals with lower ability to manage everyday technology. The META can be seen as a complement to existing ADL assessment techniques and is planned to be used in both research and practice.

    Measurement of social cognition in treatment trials remains problematic due to poor and limited psychometric data for many tasks. As part of the Social Cognition Psychometric Evaluation (SCOPE) study, the psychometric properties of 8 tasks were assessed. One hundred and seventy-nine stable outpatients with schizophrenia and 104 healthy controls completed the battery at baseline and a 2-4-week retest period at 2 sites. Tasks included the Ambiguous Intentions Hostility Questionnaire (AIHQ), Bell Lysaker Emotion Recognition Task (BLERT), Penn Emotion Recognition Task (ER-40), Relationships Across Domains (RAD), Reading the Mind in the Eyes Task (Eyes), The Awareness of Social Inferences Test (TASIT), Hinting Task, and Trustworthiness Task. Tasks were evaluated on: (i) test-retest reliability, (ii) utility as a repeated measure, (iii) relationship to functional outcome, (iv) practicality and tolerability, (v) sensitivity to group differences, and (vi) internal consistency. The BLERT and Hinting task showed the strongest psychometric properties across all evaluation criteria and are recommended for use in clinical trials. The ER-40, Eyes Task, and TASIT showed somewhat weaker psychometric properties and require further study. The AIHQ, RAD, and Trustworthiness Task showed poorer psychometric properties that suggest caution for their use in clinical trials. © The Author 2015.

    Lutenbacher, M

    2001-01-01

    The Adult-Adolescent Parenting Inventory (AAPI) is a 32-item inventory widely used to identify adolescents and adults at risk for inadequate parenting behaviors. It includes four subscales representing the most frequent patterns associated with abusive parenting: (a) Inappropriate Expectations; (b) Lack of Empathy; (c) Parental Value of Corporal Punishment; and (d) Parent-Child Role Reversal. Although it has been used in a variety of samples, the psychometric properties of the AAPI have not been examined in low-income single mothers. The purposes of this study were to: (a) examine the reliability and validity of the Adult-Adolescent Parenting Inventory (AAPI) in a sample of 206 low-income single mothers; (b) assess the mother's risk for inadequate parenting by comparing their AAPI subscale scores with normative subscale scores on the AAPI; (c) assess the construct validity of the AAPI by testing the hypothesis that mothers with lower AAPI scores have a higher level of depressive symptoms and lower self-esteem in comparison to mothers with higher AAPI scores; and (d) determine whether the 4-factor structure proposed by Bavolek (1984) could be replicated. AAPI scores indicated these mothers were at high risk for child abuse when compared with normative data for parents with no known history of abuse. Higher risk for abusive parenting was associated with a higher level of depressive symptoms, less education, and unemployment. The subscales, Inappropriate Expectations and Parental Value of Corporal Punishment demonstrated poor internal consistency with Cronbach's alphas of .40 and .54, respectively. Hypothesis testing supported the construct validity of the AAPI. Bavolek's 4-factor structure was not supported. A 19-item modified version of the AAPI with three dimensions was identified. This modified version of the AAPI may provide a more efficacious tool for use with low-income single mothers.

    1998-01-01

    The Functional Assessment Measure (FAM) has been proposed as a measure of disability in post-acute Traumatic Brain Injury (TBI) outpatients. It is comprised of the 18 items of The Functional Independence Measure (FIMSM), scored in terms of dependence, and of 12 newly designed items, scored in terms of dependence (7 items) or performance (5 items). The FIMSM covers the domains of self-care, sphincter management, mobility, locomotion, communication and social cognition. The 12 new items explore the domains of community integration, emotional status, orientation, attention, reading/writing skills, swallowing and speech intelligibility. By addressing a set of problems quite specific for TBI outpatients the FAM was intended to raise the ceiling of the FIMSM and to allow a more precise estimate of their disability. These claims, however, were never supported in previous studies. We administered the FAM to 60 TBI outpatient, 2-88 months (median 16) from trauma. Rasch analysis (rating scale model) was adopted to test the psychometric properties of the scale. The FAM was reliable (Rasch item and person reliability 0.91 and 0.93, respectively). Two of the 12 FAM-specific items were severely misfitting with the general construct, and were deleted. Within the 28-item refined FAM scale, 4 new items and 2 FIMSM items still retained signs of misfit. The FAM was on average too easy. The most difficult item (a new one, Employability) did not attain the average ability of the subjects. Also, it was only slightly more difficult than than the most difficult FIMSM item (Memory). The FAM does not seem to improve the FIMSM as a far as TBI outpatients are to be assessed.

    2010-01-01

    Background The Agency for Healthcare Research and Quality (AHRQ) Hospital Survey on Patient Safety Culture was designed to assess staff views on patient safety culture in hospital settings. The purpose of this study was to examine the multilevel psychometric properties of the survey. Methods Survey data from 331 U.S. hospitals with 2,267 hospital units and 50,513 respondents were analyzed to examine the psychometric properties of the survey's items and composites. Item factor loadings, intraclass correlations (ICCs), design effects, internal consistency reliabilities, and multilevel confirmatory factor analyses (MCFA) were examined as well as intercorrelations among the survey's composites. Results Psychometric analyses confirmed the multilevel nature of the data at the individual, unit and hospital levels of analysis. Results provided overall evidence supporting the 12 dimensions and 42 items included in the AHRQ Hospital Survey on Patient Safety Culture as having acceptable psychometric properties at all levels of analysis, with a few exceptions. The Staffing composite fell slightly below cutoffs in a number of areas, but is conceptually important given its impact on patient safety. In addition, one hospital-level model fit indicator for the Supervisor/Manager Expectations & Actions Promoting Patient Safety composite was low (CFI = .82), but all other psychometrics for this scale were good. Average dimension intercorrelations were moderate at .42 at the individual level, .50 at the unit level, and .56 at the hospital level. Conclusions Psychometric analyses conducted on a very large database of hospitals provided overall support for the patient safety culture dimensions and items included in the AHRQ Hospital Survey on Patient Safety Culture. The survey's items and dimensions overall are psychometrically sound at the individual, unit, and hospital levels of analysis and can be used by researchers and hospitals interested in assessing patient safety culture

    2002-01-01

    Objectives To explore the potential use of ultrasound measurement (SoundScan 2000 Compact, Myriad Ultrasound Systems Ltd., Rehovot, Israel), and to assess both quantitative and qualitative properties of bone. Methods The speed of sound waves (SOS; m/s) propagating along the cortical bone was determined at the tibial shaft. The performance, reliability, validity, and clinical application of this system were evaluated in Japanese subjects. Results In phantom experiments, validity of this system was 0.04(%), coefficient variation (CV: %) in same-day tests was 0.12, in five-separate-day tests was 0.13, and in independent operators was 0.11, respectively. In experiments with Japanese subjects, CV in same-day tests was 0.38, in five-separate-day tests was 0.99, and in independent operators was 0.90, respectively. In addition, cortical bone status of 1176 Japanese subjects (372 males, 804 females) was clinically evaluated by SoundScan 2000 Compact. SOS was negatively correlated with body fat percentage (%), body fat (kg) and waist hip ratio in females and subjects with higher weight bearing index (leg strength/body weight; WBI) have higher SOS in females under the age of forty. Conclusions These findings indicate that the SoundScan 2000 Compact is a highly reliable and valid method for determining cortical bone status and body composition and WBI are closely related to cortical bone status in Japanese females.

  10. Bayesian stock assessment of Pacific herring in Prince William Sound, Alaska

    2017-01-01

    The Pacific herring (Clupea pallasii) population in Prince William Sound, Alaska crashed in 1993 and has yet to recover, affecting food web dynamics in the Sound and impacting Alaskan communities. To help researchers design and implement the most effective monitoring, management, and recovery programs, a Bayesian assessment of Prince William Sound herring was developed by reformulating the current model used by the Alaska Department of Fish and Game. The Bayesian model estimated pre-fishery spawning biomass of herring age-3 and older in 2013 to be a median of 19,410 mt (95% credibility interval 12,150–31,740 mt), with a 54% probability that biomass in 2013 was below the management limit used to regulate fisheries in Prince William Sound. The main advantages of the Bayesian model are that it can more objectively weight different datasets and provide estimates of uncertainty for model parameters and outputs, unlike the weighted sum-of-squares used in the original model. In addition, the revised model could be used to manage herring stocks with a decision rule that considers both stock status and the uncertainty in stock status. PMID:28222151

  11. Assessing the sound quality of a grand piano for different tuning standards

    Fastl, Hugo

    2003-10-01

    Grand pianos are tuned to a standard frequency of 440 Hz for a4. Eighty years ago, the tuning standard was lower, around 432 Hz. In Germany, a group of music lovers insists that the sound quality of a grand piano when tuned to 432 Hz is much superior to that of the same instrument when tuned to 440 Hz. Therefore, well-controlled psychoacoustic experiments were performed to check the validity of that argument. Using a Welte-Steinway reproduction grand piano of the Deutsches Museum Muenchen, with the exception of the tuning, all other features of the pieces of music used as stimuli could be kept the same. The advantage of using the Welte-Steinway lies in the fact that reproductions of the music of famous (deceased) artists are available, who at their time performed at a lower tuning standard. Recordings of the music played at 432 vs 440 Hz were made on DAT and presented to the subjects via headphones for sound quality evaluation. Psychophysical procedures like semantic differential or preference scaling by ``random access'' that have proven successful for the assessment of sound quality in the context of car interior sounds were used in the experiments.

    2014-01-01

    The Memorial Delirium Assessment Scale (MDAS) is a reliable and validated instrument with which to assess delirium. However, MDAS responsiveness has only been investigated in an indirect way. Also, neurobehavioral and global cognitive factors seem to be the MDAS main factor loads. The primary objective of this study was to evaluate MDAS responsiveness and analyze individual factors on this scale. The secondary objective was to confirm concurrent validity and reliability of the Spanish version of the MDAS. The translation-back translation method was used to obtain the Spanish version of the MDAS. Delirium diagnosis was determined by the clinical Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria and with the Confusion Assessment Method. Responsiveness and factor loadings were determined with the Delirium Rating Scale-Revised-98, the Mini-Mental State Examination (MMSE), and the MDAS at baseline (0 hours) and at 72 hours. Variation in the scores of the Delirium Rating Scale-Revised-98 shows a correlation of r = 0.93, with variation in MDAS scores at P < 0.001. Variation in MMSE scores shows a correlation of r = -0.84, with variation in MDAS scores at P = 0.015. Factor I, neurobehavioral (reduced awareness, reduced attention, perceptual disturbance, delusions, altered psychomotor activity, and sleep-wake cycle disturbance), correlated moderately with the MMSE at -0.56. Factor II, global cognitive (disorientation, short-term memory impairment, impaired digit span, and disorganized thinking), correlated strongly with the MMSE at -0.81. Factor II was significantly more reliable than Factor I, rho = 0.7, P = 0.01. The high responsiveness confirms the value of the MDAS for ongoing delirium assessment. Two differentiated factor loadings point to a potential future need for MDAS subscales. Copyright © 2014 U.S. Cancer Pain Relief Committee. All rights reserved.

    Full Text Available The Sheehan Disability Scale (SDS assesses disability in four domains of home management, work responsibilities, close relationships and social life. The main objective of this study was to develop the Persian version of the SDS.Two steps of field work followed the Persian translation and cultural adaptation of the tool: First, the internal consistency and convergent validity was examined in 104 clinical cases recruited from inpatient and outpatient psychiatric services, using 36-item Short Form Health Survey (SF-36 and Global Assessment of Functioning (GAF. Then 88 individuals were randomly selected from the adult general population to assess internal consistency, inter-rater reliability and known group validity.In the clinical settings, Cronbach's α coefficient was 0.88 and item-total correlation ranged from 0.71 to 0.78 in various domains. The correlation between SDS and SF-36 (P< 0.001 was significant in all the areas of the performance; and neither of the correlations was statistically significant when SDS and GAF were compared. In the general population study, the SDS met a good internal consistency (α = 0.81 and known group validity, and the inter-rater reliability was perfect for "school/work responsibility ."The Persian translation of the SDS is a simple and short scale, and it seems to be a valid scale for the measurement of disability in clinical settings and in the Iranian general population.

    Full Text Available Abstract Background Cerebral palsy (CP patients have motor limitations that can affect functionality and abilities for activities of daily living (ADL. Health related quality of life and health status instruments validated to be applied to these patients do not directly approach the concepts of functionality or ADL. The Child Health Assessment Questionnaire (CHAQ seems to be a good instrument to approach this dimension, but it was never used for CP patients. The purpose of the study was to verify the psychometric properties of CHAQ applied to children and adolescents with CP. Methods Parents or guardians of children and adolescents with CP, aged 5 to 18 years, answered the CHAQ. A healthy group of 314 children and adolescents was recruited during the validation of the CHAQ Brazilian-version. Data quality, reliability and validity were studied. The motor function was evaluated by the Gross Motor Function Measure (GMFM. Results Ninety-six parents/guardians answered the questionnaire. The age of the patients ranged from 5 to 17.9 years (average: 9.3. The rate of missing data was low (disability index with the visual analogue scales was not significant; for the convergent validity CHAQ disability index had a strong correlation with the GMFM (0.77; for the divergent validity there was no correlation between GMFM and the pain and overall evaluation scales; for the criterion validity GMFM as well as CHAQ detected differences in the scores among the clinical type of CP (p disability index score (mean:2.16; SD:0.72 was higher than the healthy group (mean:0.12; SD:0.23(p Conclusion CHAQ reliability and validity were adequate to this population. However, further studies are necessary to verify the influence of the ceiling effect on the responsiveness of the instrument.

  4. Psychometric assessment of the Rat Grimace Scale and development of an analgesic intervention score.

    Directory of Open Access Journals (Sweden)

    Vanessa Oliver

    Full Text Available Our limited ability to assess spontaneous pain in rodent models of painful human conditions may be associated with a translational failure of promising analgesic compounds in to clinical use. If measurement of spontaneous pain behaviours can be used to generate an analgesic intervention score their use could expand to guide the use of analgesics, as mandated by regulatory bodies and ethical and welfare obligations. One such measure of spontaneous pain, the Rat Grimace Scale (RGS, has recently been described and shown to exhibit reliability. However, reliability of measurement scores is context and content specific, and further testing required to assess translation to a heterogenous setting (different model, raters, environment. The objectives of this study were to perform reliability testing with the Rat Grimace Scale in a heterogenous setting and generate an analgesic intervention score for its use. In a randomised, blinded study, sixteen adult female rats received one of three analgesia treatments (0.05 mg/kg buprenorphine subcutaneously, 1 mg/kg meloxicam subcutaneously, 0.2 mg/kg oral buprenorphine in jelly peri-operatively (telemetry unit implantation surgery. Rats were video-recorded (before, 1-6 and 12 hours post-operatively and images collected for independent scoring by three blinded raters using the RGS, and five experts based on "pain/no pain" assessment. Scores were used to calculate inter- and intra-rater reliability with an intraclass correlation coefficient and generate an analgesic intervention score with receiver operating characteristic curve analysis. The RGS scores showed very good inter- and intra-rater reliability (0.85 [0.78-0.90 95% CI] and 0.83 [0.76-0.89], respectively. An analgesic intervention threshold of greater than 0.67 was determined. These data demonstrate that the RGS is a useful tool which can be successfully employed in a heterogenous setting, and has the potential to guide analgesic intervention.

    2014-08-01

    Full Text Available BACKGROUND: Noise sensitivity (NS is a key construct in the fields of hygiene, planning and occupational medicine. It refers to a personality trait representing the reactivity to noise and is associated with various psycho-physiological health outcomes. AIM: This study aimed to develop a shorter version of the original Noise Sensitivity Questionnaire (NoiSeQ, retaining its dimensions and assess its validity and reliability. METHODS: A test-retest study was carried out in a convenience sample of 56 participants. A short 15-item form of the original NoiSeQ (NoiSeQSF questionnaire was developed and then administered. All major analyses were based on the coeffi cient of equivalence and stability, the generalizability theory and linear regression. RESULTS: Relative (ρ = 0.83 and absolute (ρ = 0.80 G coefficients for global NS exceeded the lower reliability limit according to G- and D-studies. Sleep subscale can readily be used to assess sleep-related NS (ρ = 0.76/θ = 0.75. Moreover, NoiSeQSF predicted some cardiac symptoms (with age of participants as a moderator factor, which demonstrated nomological validity. CONCLUSION: NoiSeQSF is a reliable estimate for global NS and NS related to sleep quality. It might prove useful to experts in environmental hygiene, urban planning and occupational diseases when dealing with noise-impaired occupational, social or psycho-physiological functioning.

  6. Assessment of motor coordination and dexterity of six years old children: A psychometric analysis

    Olívia Souza Agostini

    2014-06-01

    Full Text Available Motor coordination of six-year-old children was examined using the Assessment of Motor Coordination and Dexterity, AMCD (Avaliação da Coordenação e Destreza Motora - ACOORDEM, in order to verify test-retest reliability and investigate whether motor performance is influenced by gender, type of school and residence location. Eighty-five children were evaluated, and their parents and teachers completed questionnaires. For test-retest reliability, the AMCD was repeated with 10 children. Mann-Whitney and chi-square tests identified significant influence of sex, type of school and residence location in just a few of the test items. The test-retest reliability was moderate in the items performance, and good to excellent in the majority of the questionnaires' items. We conclude that some items should be revised and normative tables for the identification of motor delay could be created considering only the age variable. Future studies should continue the process of validating the AMCD instrument with the assessment of younger children.

  7. Explicit discrimination and health: development and psychometric properties of an assessment instrument

    2012-04-01

    Full Text Available OBJECTIVE: To develop an instrument to assess discrimination effects on health outcomes and behaviors, capable of distinguishing harmful differential treatment effects from their interpretation as discriminatory events. METHODS: Successive versions of an instrument were developed based on a systematic review of instruments assessing racial discrimination, focus groups and review by a panel comprising seven experts. The instrument was refined using cognitive interviews and pilot-testing. The final version of the instrument was administered to 424 undergraduate college students in the city of Rio de Janeiro, Southeastern Brazil, in 2010. Structural dimensionality, two types of reliability and construct validity were analyzed. RESULTS: Exploratory factor analysis corroborated the hypothesis of the instrument's unidimensionality, and seven experts verified its face and content validity. The internal consistency was 0.8, and test-retest reliability was higher than 0.5 for 14 out of 18 items. The overall score was higher among socially disadvantaged individuals and correlated with adverse health behaviors/conditions, particularly when differential treatments were attributed to discrimination. CONCLUSIONS: These findings indicate the validity and reliability of the instrument developed. The proposed instrument enables the investigation of novel aspects of the relationship between discrimination and health.

    Aidman, Eugene V; Shmelyov, Alexander G

    2002-02-01

    This paper describes an interactive software environment designed as a social interaction simulator with embedded comprehensive recording and flexible assessment facilities. Using schematized visual sketches similar to cross-cultural facial universals (Ekman, 1999), Mimics (Shmelyov & Aidman, 1997) employs a computer-game-like scenario that requires the subject to identify with an avatar and navigate it through a playing field inhabited by hosts who display a range of facial expressions. From these expressions (which are highly consequential), the player has to anticipate the hosts' reactions to the avatar (which may vary from friendly to obstructing or aggressive) and choose between negotiating with a host (by altering the avatar's facial expression), attacking it, or searching for an escape route. Comprehensive recording of player moves and interactions has enabled computation of several finegrained indices of interactive behavior, such as aggressive response styles, efficiency, and motivation in conflict/cooperation contexts. Initial validation data and potential applications of the method in the assessment of personality and social behavior are discussed.

    Objective: The Computerized and Dynamic Writing Test (TIDE) is designed to examine the learning potential of adolescents in narrative writing. This was a validation study of the TIDE based on its internal structure. Learning potential is responsible for cognitive modifiabilty according to the Theory of Cognitive Structural Modifiability (CSM) developed by Feüerstein. Method: Included 304 participants between 10 and 17 years of age from schools in the South of Brazil. The data collection involved student groups that were divided according to age and school grade. Each participant reponded to the TIDE for an average of 50 min in the school's computer lab. The participants' selection criteria were: being regularly enrolled in the fifth to eighth grade and providing an informed consent form signed by a responsible caregiver. The exclusion criteria included: neurological problems, having been held back in school for two or more years, not cooperating, not completing the test for any reason and physical conditions impeding the assessment. Results: The Kendall test indicated agreement between two evaluators, who corrected the participants' first and second texts that resulted from applying the TIDE. The TIDE is divided into three modules. Factor analysis was applied to the first module (pre-test), which revealed a division in two factors, and to the second module (instructional module), which was divided in three factors. The reliability of the TIDE items was verified using Cronbach's Alpha with coefficients >0.7. The analysis of the third module (post-test) was based on McNemar's Test and showed statistically significant results that demonstrated an evolution in the participants' learning potential. Conclusion: The TIDE proved to be valid and is considered a relevant tool for speech, language, hearing, psychological and educational assessment. The original nature of the tool presented here is highlighted, based on the dynamic assessment method, offering data on a

    Research suggests that women pretend orgasm with their partner as a mate retention strategy, but the cognitive reasons behind this deception are not well known. To explore women's cognitive reasons for pretending orgasm, we first assembled a list of the reasons women report for pretending orgasm. We refined this list using independent data collected on performance frequencies for each item, followed by a principal components analysis, to generate the Reasons for Pretending Orgasm Inventory (RPOI). We found three components encompassing the cognitive reasons women pretend orgasm: Improve Partner's Experience (i.e., increasing the quality of the sexual experience for the partner), Deception and Manipulation (i.e., deceiving the partner or manipulating his perceptions for other gains), and Hiding Sexual Disinterest (i.e., sparing the partner's feelings about the woman's lack of sexual excitement). Discussion highlights limitations of this research and the RPOI, but suggests that the RPOI is useful as a structured means for assessing women's reasons for pretending orgasm.

    2015-04-01

    Full Text Available This study presents the measurement properties of 5 scales used in the Healthcare Provider Cultural Competence Instrument (HPCCI. The HPCCI measures a health care provider’s cultural competence along 5 primary dimensions: (1 awareness/sensitivity, (2 behaviors, (3 patient-centered communication, (4 practice orientation, and (5 self-assessment. Exploratory factor analysis demonstrated that the 5 scales were distinct, and within each scale items loaded as expected. Reliability statistics indicated a high level of internal consistency within each scale. The results indicate that the HPCCI effectively measures the cultural competence of health care providers and can provide useful professional feedback for practitioners and organizations seeking to increase a practitioner’s cultural competence.

    2016-01-01

    The National Marine Fisheries Service (NMFS) currently uses interim criteria developed on the US West Coast to assess the potential onset of peak and cumulative effects of noise on fishes. Analyses performed for this project provided adequate support for the NMFS to use the peak criterion (i.e., area ensonified by 206 dB re 1 μPa peak sound pressure level [SPL(peak)]) for estimating the incidental take of Hudson River sturgeon. Application of the peak criterion (rather than the cumulative criterion) could have implications for future construction projects because estimates of take using SPL(peak) will generally be considerably lower than estimates of take based on the cumulative sound exposure level.

    Background A thorough analysis of continuous adventitious sounds (CAS) can provide distinct and complementary information about bronchodilator response (BDR), beyond that provided by spirometry. Nevertheless, previous approaches to CAS analysis were limited by certain methodology issues. The aim of this study is to propose a new integrated approach to CAS analysis that contributes to improving the assessment of BDR in clinical practice for asthma patients. Methods Respiratory sounds and flow were recorded in 25 subjects, including 7 asthma patients with positive BDR (BDR+), assessed by spirometry, 13 asthma patients with negative BDR (BDR-), and 5 controls. A total of 5149 acoustic components were characterized using the Hilbert spectrum, and used to train and validate a support vector machine classifier, which distinguished acoustic components corresponding to CAS from those corresponding to other sounds. Once the method was validated, BDR was assessed in all participants by CAS analysis, and compared to BDR assessed by spirometry. Results BDR+ patients had a homogenous high change in the number of CAS after bronchodilation, which agreed with the positive BDR by spirometry, indicating high reversibility of airway obstruction. Nevertheless, we also found an appreciable change in the number of CAS in many BDR- patients, revealing alterations in airway obstruction that were not detected by spirometry. We propose a categorization for the change in the number of CAS, which allowed us to stratify BDR- patients into three consistent groups. From the 13 BDR- patients, 6 had a high response, similar to BDR+ patients, 4 had a noteworthy medium response, and 1 had a low response. Conclusions In this study, a new non-invasive and integrated approach to CAS analysis is proposed as a high-sensitive tool for assessing BDR in terms of acoustic parameters which, together with spirometry parameters, contribute to improving the stratification of BDR levels in patients with

    Describe the development of the leading by example (LBE) instrument. A total of 135 responses from employees of a private corporation working at 11 different worksites were factor analyzed in 2005. Exploratory factor analysis was used to obtain an initial factor structure. Factor validity was evaluated using confirmatory factor analysis methods. A second sample was collected in 2006 from the same population (N = 178) and was used to confirm the factor structure via confirmatory factor analysis. Cronbach's alpha and item-total correlations provided information on the reliability of the factor subscales. Four subscales were identified: business alignment with health promotion objectives, awareness of the health-productivity link, worksite support for health promotion, and leadership support for health promotion. Factor by group comparisons revealed that the initial factor structure was effective in detecting differences in organizational support for health promotion across different employee groups. Management support for health promotion can be assessed using the LBE, a brief self-report questionnaire. Researchers can use the LBE to diagnose, track, and evaluate worksite health promotion programs.

    Full Text Available Research suggests that women pretend orgasm with their partner as a mate retention strategy, but the cognitive reasons behind this deception are not well known. To explore women's cognitive reasons for pretending orgasm, we first assembled a list of the reasons women report for pretending orgasm. We refined this list using independent data collected on performance frequencies for each item, followed by a principal components analysis, to generate the Reasons for Pretending Orgasm Inventory (RPOI. We found three components encompassing the cognitive reasons women pretend orgasm: Improve Partner's Experience (i.e., increasing the quality of the sexual experience for the partner, Deception and Manipulation (i.e., deceiving the partner or manipulating his perceptions for other gains, and Hiding Sexual Disinterest (i.e., sparing the partner's feelings about the woman's lack of sexual excitement. Discussion highlights limitations of this research and the RPOI, but suggests that the RPOI is useful as a structured means for assessing women's reasons for pretending orgasm.

    Clinical tests used for psychodiagnostic purposes, such as the well-known Alzheimer's Disease Assessment Scale: Cognitive subscale (ADAS-Cog), include a free-recall task. The free-recall task taps into latent cognitive processes associated with learning and memory components of human cognition, any of which might be impaired with the progression of Alzheimer's disease (AD). A Hidden Markov model of free recall is developed to measure latent cognitive processes used during the free-recall task. In return, these cognitive measurements give us insight into the degree to which normal cognitive functions are differentially impaired by medical conditions, such as AD and related disorders. The model is used to analyze the free-recall data obtained from healthy elderly participants, participants diagnosed as having mild cognitive impairment, and participants diagnosed with early AD. The model is specified hierarchically to handle item differences because of the serial position curve in free recall, as well as within-group individual differences in participants' recall abilities. Bayesian hierarchical inference is used to estimate the model. The model analysis suggests that the impaired patients have the following: (1) long-term memory encoding deficits, (2) short-term memory (STM) retrieval deficits for all but very short time intervals, (3) poorer transfer into long-term memory for items successfully retrieved from STM, and (4) poorer retention of items encoded into long-term memory after longer delays. Yet, impaired patients appear to have no deficit in immediate recall of encoded words in long-term memory or for very short time intervals in STM.

    Hepatic steatosis is a common condition, the prevalence of which is increasing along with non-alcoholic fatty liver disease (NAFLD). Currently, the most accurate noninvasive imaging method for diagnosing and quantifying hepatic steatosis is MRI, which estimates the proton-density fat fraction (PDFF) as a measure of fractional fat content. However, MRI suffers several limitations including cost, contra-indications and poor availability. Although conventional ultrasound is widely used by radiologists for hepatic steatosis assessment, it remains qualitative and operator dependent. Interestingly, the speed of sound within soft tissues is known to vary slightly from muscle (1.575 mm · µs-1) to fat (1.450 mm · µs-1). Building upon this fact, steatosis could affect liver sound speed when the fat content increases. The main objectives of this study are to propose a robust method for sound speed estimation (SSE) locally in the liver and to assess its accuracy for steatosis detection and staging. This technique was first validated on two phantoms and SSE was assessed with a precision of 0.006 and 0.003 mm · µs-1 respectively for the two phantoms. Then a preliminary clinical trial (N  =  17 patients) was performed. SSE results was found to be highly correlated with MRI proton density fat fraction (R 2  =  0.69) and biopsy (AUROC  =  0.952) results. This new method based on the assessment of spatio-temporal properties of the local speckle noise for SSE provides an efficient way to diagnose and stage hepatic steatosis.

  10. Assessment of stress state of rock mass with the help of seismic soundings

    Method of measurement using seismic soundings without drilling boreholes is described. A physical basis is provided for the method used and the results are supplied for the assessment of the stress state of rock mass in the Norilsk coal basin. In the last few years, wide use has been made of linear profiling without drilling boreholes in order to determine the stress state of rock needed for predicting outbursts in coal seams. The method can be used to investigate rectilinear sections of mine workings which are over 20 m. However, in order to resolve a variety of mine problems, e.g. predicting and investigating dynamic phenomena, it is necessary to acquire information about the state of rock mass up to 10 to 15 m. With this in mind the VNIMI has developed a new variant of seismic sounding without the need to drill boreholes which, unlike other known methods, makes it possible to determine parameters of the abutment pressure along the whole perimeter of the rock mass in question. The investigations carried out indicate that the increases and decreases in stress as well as the rise and fall in the rate of stress wave propagation in the abutment zone can be approximated with sufficient accuracy by line segments. Results of the investigations obtained with the help of seismic soundings at the Oktyabrskii mine, Norilsk coal basin, are given.

    Full Text Available Introduction: The existence of standard tools is one of the basic needs of scientists of healthy behavior for predicting health-related behaviors. The aim of the present study was to design a psychometrically sound instrument to measure the protection motivation theory constructs regarding self-medication for elderly Iranians. Methods: The study was conducted in spring 2016. The sample consisted of 196 Iranians between the ages of 60 and 74. The study took place in Ahvaz, Iran.  The instrument included perceived susceptibility, severity, response costs, response efficacy, self-efficacy, rewards, and fear constructs. The qualitative component of the study, which consisted of interviews with experts and a systematic review of the literature, provided the data to write the items for the instrument, followed by determining the content validity. Principal components analysis with Oblique rotation was performed to extract correlated constructs. The Kaiser-Meyer-Olkin (KMO and Bartlett's tests were performed to examine the suitability of the data for factor analysis. Cronbach’s Coefficient Alpha was used to estimate the internal consistency of the scales. Results: The KMO test statistic of 0.90 revealed the sampling adequacy for doing factor analysis and Bartlett's test of sphericity was significant (p < 0.001. Seven constructs were extracted based on Eigenvalues of ≥ 1.00 and factor loadings of ≥ 0.40. Cronbach’s α for the constructs, namely, perceived susceptibility, severity, response costs, response efficacy, self-efficacy, rewards and fear were 0.84, 0.86, 0.81, 0.82, 0.88, 0.89, and 0.85, respectively.  The seven constructs accounted for 69.41% of the variation. Conclusion: The developed scales for measuring the protection motivation theory constructs regarding self-medication have acceptable psychometric properties among elderly Iranians.

    The Edmonton Symptom Assessment System (ESAS) is a measure widely used in palliative care for the assessment of symptoms in patients with advanced cancer. The tool has been validated in different languages, including Spanish. A revised version (ESAS-r) was developed by Watanabe et al. in 2010. To develop the Spanish version of the ESAS-r and examine its psychometric properties. Based on the original English version, a group of experts created a Spanish version of the ESAS-r and administered it to a group of advanced cancer patients. Patients completed the ESAS and ESAS-r and were asked for their perceptions of the tool. The psychometric properties of the ESAS-r that were analyzed were equivalence, internal consistency, and discriminant validity. Sixty-six patients from Spain and Guatemala participated in the survey. Patients perceived the ESAS-r to be significantly easier to understand and easier to complete than the ESAS. Significantly, patients preferred the ESAS-r (47%) to the ESAS (15%; P<0.0007). As to reliability, we found good internal consistency (Cronbach's alpha 0.86), and the equivalence of the two versions was between 0.71 and 0.94. The ESAS-r discriminates between inpatients and outpatients (Mann-Whitney U test; P=0.02) and among those with different palliative performance status (Spearman's rho for pain, tiredness, drowsiness, lack of appetite, well-being; P<0.01). The ESAS-r is a valid instrument with adequate psychometric characteristics. This version is preferred by patients with advanced cancer. The Spanish version of the ESAS-r can, therefore, replace the use of the ESAS. Copyright © 2013 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc. All rights reserved.

    This paper describes the translation, cultural adaption, and psychometric evaluation of a German version of the Health Education Impact Questionnaire (heiQ™), a widely used generic instrument assessing a wide range of proximal outcomes of self-management programs. The translation was carried out according to international standards and included forward and backward translations. Comprehensibility and content validity were tested using cognitive interviews with 10 rehabilitation inpatients. Psychometric properties were examined in rehabilitation inpatients (n = 1,202) with a range of chronic conditions. Factorial validity was assessed using confirmatory factor analysis; concurrent validity was explored by correlations with comparator scales. The items of the German heiQ™ were well understood by rehabilitation inpatients. The structure of the eight heiQ™ scales was replicated after minor adjustment. heiQ™ scales had higher correlations with comparator scales with similar constructs, particularly mental health concepts than with physical health. Moreover, all heiQ™ scales differentiated between individuals across different levels of depression. The German heiQ™ is comprehensible for German-speaking patients suffering from different types of chronic conditions; it assesses relevant outcomes of self-management programs in a reliable and valid manner. Further studies involving its practical application are warranted.

    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.

    The study explored the psychometric properties of the Arabic version of the ISMI measure on an Arab sub-sample (N = 330) in a health clinic that served mostly refugees in Michigan, USA. Study measures included the ISMI, PTSD, depression, anxiety, CTD (Cumulative Trauma Disorders), and traumatic stress measures. Data analysis included factor analysis, correlation, and multiple regression analysis. The Arabic form of the measure was found to have robust psychometric qualities, with high reliability construct and predictive validity. Factor analysis identified a general stigma factor and different levels of stigma resistance factors. General stigma was significantly associated with and predicted post-trauma symptoms of depression, anxiety, PTSD and CTD (complex PTSD), while tough stigma resistance was associated negatively with PTSD and depression and positively with positive appraisal of traumatic events. © The Author(s) 2015.

    2014-06-01

    This article describes the development and field test of the Sound Concept Inventory Instrument (SCII), designed to measure middle school students' concepts of sound. The instrument was designed based on known students' difficulties in understanding sound and the history of science related to sound and focuses on two main aspects of sound: sound has material properties, and sound has process properties. The final SCII consists of 71 statements that respondents rate as either true or false and also indicate their confidence on a five-point scale. Administration to 355 middle school students resulted in a Cronbach alpha of 0.906, suggesting a high reliability. In addition, the average percentage of students' answers to statements that associate sound with material properties is significantly higher than the average percentage of statements associating sound with process properties (p <0.001). The SCII is a valid and reliable tool that can be used to determine students' conceptions of sound.

    2009-08-01

    This study aimed to develop a new psychometric instrument to assess vulnerability to risk of suicide and nonfatal self-harm behaviour in young adult male and female offenders. In total three studies were conducted to assess the psychometric properties of the new instrument using both exploratory and confirmatory factor analysis in different samples. Participants in all three studies included a total of 1,166 young adult offenders across six Her Majesty's Prisons. The new instrument, Suicide Concerns for Offenders in Prison Environment (SCOPE), contained 28 items scoring on two subscales. The factorial structure of the new instrument initially obtained with exploratory factor analysis was subsequently confirmed in a new sample. The internal consistency of the two subscales were acceptable but the test-retest reliability coefficients were moderate. Concurrent validation with the Beck Hopelessness Scale was acceptable and SCOPE showed the ability to discriminate between those at risk and those with no known history of attempted suicide and nonfatal self-harm behaviour ( p < 0.01).

    Background Safety culture assessment is increasingly recognized as an important component in healthcare quality improvement, also in pharmacies. One of the most commonly used and rigorously validated tools to measure safety culture is the Safety Attitudes Questionnaire; SAQ. This study presents the validation of the SAQ for use in Swedish pharmacies. The psychometric properties of the translated questionnaire are presented Methods The original English language version of the SAQ was translated and adapted to the Swedish context and distributed by e-mail. The survey was carried out on a national basis, covering all 870 Swedish community pharmacies. In total, 7,244 questionnaires were distributed. Scale psychometrics were analysed using Cronbach alphas and intercorrelations among the scales. Multiple group confirmatory factor analysis (CFA) was conducted. Results SAQ data from 828 community pharmacies in Sweden, including 4,090 (60.22%) pharmacy personnel out of 6,683 eligible respondents, were received. There were 252 (28.97%) pharmacies that met the inclusion criteria of having at least 5 respondents and a minimum response rate of 60% within that pharmacy. The coefficient alpha value for each of the SAQ scales ranged from .72 to .89. The internal consistency results, in conjunction with the confirmatory factor analysis results, demonstrate that the Swedish translation of the SAQ has acceptable to good psychometric properties. Perceptions of the pharmacy (Teamwork Climate, Job Satisfaction, Perceptions of Management, Safety Climate, and Working Conditions) were moderately to highly correlated with one another whereas attitudes about stress (Stress Recognition) had only low correlations with other factors. Perceptions of management showed the most variability across pharmacies (SD = 26.66), whereas Stress Recognition showed the least (SD = 18.58). There was substantial variability ranging from 0% to 100% in the percent of positive scores for each of the factors

    To assess the content validity and psychometric characteristics of the Knowledge about Older Patients Quiz (KOP-Q), which measures nurses' knowledge regarding older hospitalized adults and their certainty regarding this knowledge. Cross-sectional. Content validity: general hospitals. Psychometric characteristics: nursing school and general hospitals in the Netherlands. Content validity: 12 nurse specialists in geriatrics. Psychometric characteristics: 107 first-year and 78 final-year bachelor of nursing students, 148 registered nurses, and 20 nurse specialists in geriatrics. Content validity: The nurse specialists rated each item of the initial KOP-Q (52 items) on relevance. Ratings were used to calculate Item-Content Validity Index and average Scale-Content Validity Index (S-CVI/ave) scores. Items with insufficient content validity were removed. Psychometric characteristics: Ratings of students, nurses, and nurse specialists were used to test for different item functioning (DIF) and unidimensionality before item characteristics (discrimination and difficulty) were examined using Item Response Theory. Finally, norm references were calculated and nomological validity was assessed. Content validity: Forty-three items remained after assessing content validity (S-CVI/ave = 0.90). Psychometric characteristics: Of the 43 items, two demonstrating ceiling effects and 11 distorting ability estimates (DIF) were subsequently excluded. Item characteristics were assessed for the remaining 30 items, all of which demonstrated good discrimination and difficulty parameters. Knowledge was positively correlated with certainty about this knowledge. The final 30-item KOP-Q is a valid, psychometrically sound, comprehensive instrument that can be used to assess the knowledge of nursing students, hospital nurses, and nurse specialists in geriatrics regarding older hospitalized adults. It can identify knowledge and certainty deficits for research purposes or serve as a tool in educational

    Dysphagia can have severe consequences for the patient's health, influencing health-related quality of life (HRQoL). Sound psychometric properties of HRQoL questionnaires are a precondition for assessing the impact of dysphagia, the focus of this study, resulting in recommendations for the appropriate use of these questionnaires in both clinical practice and research contexts. We performed a systematic review starting with a search for and retrieval of all full-text articles on the development of HRQoL questionnaires related to oropharyngeal dysphagia and/or their psychometric validation from the electronic databases PubMed and Embase published up to June 2011. Psychometric properties were judged according to quality criteria proposed for health status questionnaires. Eight questionnaires were included in this study. Four are aimed solely at HRQoL in oropharyngeal dysphagia: the deglutition handicap index (DHI), dysphagia handicap index (DHI'), M.D. Anderson Dysphagia Inventory (MDADI), and SWAL-QOL, while the EDGQ, EORTC QLQ-STO 22, EORTC QLQ-OG 25 and EORTC QLQ-H&N35 focus on other primary diseases resulting in dysphagia. The psychometric properties of the DHI, DHI', MDADI, and SWAL-QOL were evaluated. For appropriate applicability of HRQoL questionnaires, strong scores on the psychometric criteria face validity, criterion validity, and interpretability are prerequisites. The SWAL-QOL has the strongest ratings for these criteria, while the DHI' is the most easy to apply given its 25 items and the use of a uniform scoring format. For optimal use of HRQoL questionnaires in diverse settings, it is necessary to combine psychometric and utility approaches.

    There is no difference in principle between the infrasonic and ultrasonic sounds, which are inaudible to humans (or other animals) and the sounds that we can hear. In all cases, sound is a wave of pressure and particle oscillations propagating through an elastic medium, such as air. This chapter...... is about the physical laws that govern how animals produce sound signals and how physical principles determine the signals’ frequency content and sound level, the nature of the sound field (sound pressure versus particle vibrations) as well as directional properties of the emitted signal. Many...... of these properties are dictated by simple physical relationships between the size of the sound emitter and the wavelength of emitted sound. The wavelengths of the signals need to be sufficiently short in relation to the size of the emitter to allow for the efficient production of propagating sound pressure waves...

    Elementary school-age child report instruments that do not require reading or interviews are lacking. In four samples, psychometric estimates for 5- to 9-year-olds were obtained for the Assessment of Liability and Exposure to Substance use and Antisocial behavior© (ALEXSA©), a child-report instrument that can be completed even by illiterate children. Invariance between minority groups vs Caucasians also was tested. Samples were: high-risk, low SES African-Americans (n=337), youth of varied ethnicities experiencing chronic stress (n=209), Mexican migrants in a reading remediation program (n=45), and U.S. twins (42 pairs) who were nearly all Caucasian. Validity criteria consisted of child-, parent-, teacher- and research evaluator-ratings on previously developed research and clinical instruments. Replicating results with older samples, ALEXSA factors had adequate or better reliabilities and demonstrated validity in all four studies. Ethnic invariance was found except for differences that were expected due to migrant's after-school program. In sum, psychometrics of the ALEXSA were supported for 5- to 9-year-olds of varied races/ethnicities, risk levels and academic skills. PMID:22866171

    The Zarit Burden Interview (ZBI) was originally developed to assess the level of subjective burden in caregivers of people with dementia. The Involvement Evaluation Questionnaire (IEQ) is amongst the leading scales to assess caregiving consequences in severe mental illness. We aimed to compare the psychometric properties of the ZBI, a generic tool, and of the IEQ, a more specific tool to assess the consequences of caregiving in schizophrenia and related disorders. Secondary analyses of a 16-week, randomized controlled trial of a psychoeducational intervention in 223 primary caregivers of patients with schizophrenia or schizoaffective disorder. Psychometric properties (internal consistency, convergent and discriminative validity, and sensitivity to change) were evaluated for both ZBI and IEQ. Internal consistency was good and similar for both scales (ZBI: 0.91, 95% CI: 0.89, 0.94; IEQ: 0.86, 95% CI: 0.83, 0.89). Convergent validity was relevant for similar domains (e.g. ZBI total score vs IEQ-tension r = 0.69, 95% CI: 0.61, 0.75) and at least moderate for the rest of domains (ZBI total score, personal strain and role strain vs IEQ-urging and supervision). Discriminative validity against psychological distress and depressive symptoms was good (Area Under the Curve [AUC]: 0.77, 95% CI: 0.71, 0.83; and 0.69, 95% CI: 0.63, 0.78 - for ZBI against GHQ-28 and CES-D respectively; and AUC: 0.72, 95% CI: 0.65, 0.78; and 0.69, 95% CI: 0.62, 0.77 - for IEQ against GHQ-28 and CES-D respectively). AUCs against the reference criteria did not differ significantly between the two scales. After the intervention, both scales showed a significant decrease at endpoint (p-values psychometric properties to assess caregiver burden in this sample.

    The volume of air that goes in and out of a musical instrument's sound hole is related to the sound hole's contribution to the volume of the sound. Helmholtz's result for the simplest case of steady flow through an elliptical hole is reviewed. Measurements on multiple holes in sound box geometries and scales relevant to real musical instruments demonstrate the importance of a variety of effects. Electric capacitance of single flat plates is a mathematically identical problem, offering an alternate way to understand the most important of those effects. The measurements also confirm and illuminate aspects of Helmholtz's "bottle" resonator model as applied to musical instrument sound boxes and sound holes.

    Novel care-technologies possess a transformational potential. Future care and support may be provided via monitoring technologies such as smart devices, sensors, actors (robots) and Information and Communication Technologies. Such technologies enable care provision outside traditional care institutions, for instance in the homes of patients. Health monitoring may become "personalized" i.e. tailored to the needs of individual care recipients' but may also alter relations between care providers and care recipents, shape and form the care environment and influence values central to health-care. Starting out from a social constructivist theory of technology, an interactive ethical assessment-model is offered. The suggested model supplements a traditional analysis based on normative ethical theory (top-down approach) with interviews including relevant stakeholders (a bottom-up approach). This method has been piloted by small-scale interviews encircling stakeholder perspectives on three emerging technologies: (1) Careousel, a smart medicine-management device, (2) Robot Giraff, an interactive and mobile communication-device and (3) I-Care, a care-software that combines alarm and register system. By incorporating stakeholder perspectives into the analysis, the interactive ethical assessment model provides a richer understanding of the impact of PHM-technologies on ethical values than a traditional top-down model. If the assessment is conducted before the technology has reached the market - preferably in close interaction with developers and users - ethically sound technologies may be obtained.

    Full Text Available The Achenbach and Edelbrock Child Behavior Checklist was assessed psychometrically in a group of 100 preschool students between 4,0 and 5,5 years old who attend a public school at Bogota city. It was done by applying formats to parents and teachers. These formats were previously translated, linguistically adapted and piloted. The Cronbach’s Alpha for the total scale was 0,94 -0,94 for parents and 0,95 for teachers-. The analysis of factors by main components saturated the variance in 87%, although it did not correspond to the factors proposed by the original model. This measure gives diagnostic information about the children’s behavioral structure from a multiaxial perspective. Moreover, it identifies profiles of the internalizing and externalizing dimensions of behavior.

    Although elder mistreatment among ethnic minorities is increasingly gaining attention, our empirical knowledge of this phenomenon among American Indians remains quite limited, especially with respect to measurement. The Shielding American Indian Elders (SAIE) Project used a collaborative approach to explore culturally informed measurement of elder mistreatment in two American Indian elder samples (a Northern Plains reservation and a South Central metropolitan area). The project sought to investigate the performance characteristics of the commonly used Hwalek-Sengstock Elder Abuse Screening Test (HS-EAST), as well as to examine the psychometric properties of a new measure developed to capture culturally salient aspects of mistreatment in American Indian contexts--the Native Elder Life Scale (NELS). Using methods and samples comparable to those in the literature, the HS-EAST performed adequately in these Native samples. The NELS also shows promise for use with this population and assesses different aspects of elder mistreatment than does the HS-EAST.

  13. Sound quality assessment of Diesel combustion noise using in-cylinder pressure components

    The combustion process in direct injection (DI) Diesel engines is an important source of noise, and it is thus the main reason why end-users could be reluctant to drive vehicles powered with this type of engine. This means that the great potential of Diesel engines for environment preservation—due to their lower consumption and the subsequent reduction of CO2 emissions—may be lost. Moreover, the advanced combustion concepts—e.g. the HCCI (homogeneous charge compression ignition)—developed to comply with forthcoming emissions legislation, while maintaining the efficiency of current engines, are expected to be noisier because they are characterized by a higher amount of premixed combustion. For this reason many efforts have been dedicated by car manufacturers in recent years to reduce the overall level and improve the sound quality of engine noise. Evaluation procedures are required, both for noise levels and sound quality, that may be integrated in the global engine development process in a timely and cost-effective manner. In previous published work, the authors proposed a novel method for the assessment of engine noise level. A similar procedure is applied in this paper to demonstrate the suitability of combustion indicators for the evaluation of engine noise quality. These indicators, which are representative of the peak velocity of fuel burning and the resonance in the combustion chamber, are well correlated with the combustion noise mark obtained from jury testing. Quite good accuracy in the prediction of the engine noise quality has been obtained with the definition of a two-component regression, which also permits the identification of the combustion process features related to the resulting noise quality, so that corrective actions may be proposed.

    An expanded model to conceptualize sacred human experiences is discussed wherein the term Spirituality is broadened to include: (1) Ritualistic Spirituality, (2) Theistic Spirituality, and (3) Existential Spirituality. However, a measure incorporating this expanded model does not yet exist. A 67-item self-report questionnaire was developed and data were collected from 1,301 undergraduate students. A series of factor analytic procedures yielded a three-factor structure consistent with the guiding theoretical model and refinement produced three 10-item subscales. Evidence for construct validity and sound psychometric properties was indicative of a reliable, valid, and unique tool to assess the multidimensional nature of spirituality.

    The purpose of this paper was to assess the psychometric properties of the Students' Life Satisfaction Scale (SLSS) and the Brief Multidimensional Students' Life Satisfaction Scale (BMSLSS) when used with youth who have chronic conditions. Baseline data from a longitudinal study examining predictors of changes in perceived quality of life (PQOL) for youth with chronic conditions were used. SLSS and BMSLSS data were collected on over 400 youth aged 11-17 using youth self-report and parent proxy-report versions. Internal consistency, convergent validity, and factor structure were examined for both versions. Extent of agreement and magnitude of differences between youth and parent report were evaluated. Finally, gender, age, and condition group differences in youth report scores were examined for the SLSS and BMSLSS. Strong internal consistency was demonstrated for the youth and parent reports of both measures. As with normative samples, a single factor structure was found for youth and parent reports of the BMSLSS. However, both youth and parent reports of the SLSS had a two-factor structure: one consisting of five positively worded items, and the other, two negatively worded items. Youth reported their PQOL to be significantly higher than did their parents. Significant differences in PQOL scores for the youth report were not found by age, gender, or conditions. Findings show that, from a psychometric standpoint, the BMSLSS (both youth and parent report) is a promising measure of PQOL for use in population-based research with youth who have chronic conditions. The SLSS may need to be revised to exclude negative items when used with this population of youth.

    Family functioning plays an important role in developing and maintaining dysfunctional behaviors, especially during adolescence. The lack of indicators of family functioning, as determinants of personal and interpersonal problems, represents an obstacle to the activities aimed at developing preventive and intervention strategies. The Process Model of Family Functioning provides a conceptual framework organizing and integrating various concepts into a comprehensive family assessment; this model underlines that through the process of task accomplishment, each family meets objectives central to its life as a group. The Family Assessment Measure Third Edition (FAM III), based on the Process Model of Family Functioning, is among the most frequently used self-report instruments to measure family functioning. The present study aimed to evaluate the psychometric properties of the Italian version of the Family Assessment Measure Third Edition - Short Version (Brief FAM-III). It consists of three modules: General Scale, which evaluates the family as a system; Dyadic Relationships Scale, which examines how each family member perceives his/her relationship with another member; and Self-Rating Scale, which indicates how each family member is perceived within the nucleus. The developed Brief FAM-III together with the Family Assessment Device were administered to 484 subjects, members of 162 Italian families, formed of 162 fathers aged between 35 and 73 years; 162 mothers aged between 34 and 69 years; and 160 children aged between 12 and 35 years. Correlation, paired-sample t-test, and reliability analyses were carried out. General item analysis shows good indices of reliability with Cronbach's α coefficients equal to 0.96. The Brief FAM-III has satisfactory internal consistency, with Cronbach's α equal to 0.90 for General Scale, 0.94 for Dyadic Relationships Scale, and 0.88 for the Self-Rating Scale. The Brief FAM-III can be a psychometrically reliable and valid measure for

    Abstract Background  Growing recognition of the role of citizens and patients in health and health care has placed a spotlight on health literacy and patient education. Objective  To identify specific competencies for health in definitions of health literacy and patient‐centred concepts and empirically test their dimensionality in the general population. Methods  A thorough review of the literature on health literacy, self‐management, patient empowerment, patient education and shared decision making revealed considerable conceptual overlap as competencies for health and identified a corpus of 30 generic competencies for health. A questionnaire containing 127 items covering the 30 competencies was fielded as a telephone interview in German, French and Italian among 1255 respondents randomly selected from the resident population in Switzerland. Findings  Analyses with the software MPlus to model items with mixed response categories showed that the items do not load onto a single factor. Multifactorial models with good fit could be erected for each of five dimensions defined a priori and their corresponding competencies: information and knowledge (four competencies, 17 items), general cognitive skills (four competencies, 17 items), social roles (two competencies, seven items), medical management (four competencies, 27 items) and healthy lifestyle (two competencies, six items). Multiple indicators and multiple causes models identified problematic differential item functioning for only six items belonging to two competencies. Conclusions  The psychometric analyses of this instrument support broader conceptualization of health literacy not as a single competence but rather as a package of competencies for health.

    The study describes the development and psychometric evaluation of a self-report questionnaire for use in both treatment-outcome research and process studies: the Agoraphobic Self-Statements Questionnaire (ASQ). The ASQ comprises two subscales: a positive self-statements subscale and a negative self-statements subscale. Confirmatory factor analysis showed that, with the exception of one item, the proposed bidimensional structure of the ASQ reappeared in a second agoraphobic patient sample. Internal consistency of both subscales was satisfactory. Both subscales appeared to be sensitive to change in treatment and discriminated between agoraphobic patients and normal controls. Construct validity of the negative subscale was satisfactory, whilst additional validation of the positive subscale is required. Findings also revealed that positive thinking may serve as a coping device and that the occurrence of negative self-statements might be considered a sine qua non for the occurrence of positive self-statements. It is concluded that the ASQ can contribute to the understanding of cognitive processes during treatment of agoraphobia.

    The technique discussed, the Topographic Air Pollution Analysis System (TAPAS), was developed to provide valid information on the dispersion capability of the lower atmosphere in areas characterized by complex terrain features. A study was undertaken to assess the air quality (SO/sub 2/) impacts associated with energy development in the region and to determine the constraints on energy development due to regulated limitations on the amount of air quality degradation allowable in the area. The emission constraint analysis for the northern Puget Sound region indicated that total SO/sub 2/ emissions in the core area (on an annual basis) are less than half of the amount that could be tolerated in the entire core region while maintaining ambient concentrations within state and federal annual average limitations. However, comparison of source characteristics with source location and grid cell emission restrictions indicated that localized areas adjacent to the major point sources are already far in excess of the SO/sub 2/ carrying capacity. This conclusion is supported by air quality monitoring data that indicate state standard violations at several receptor locations within the study area. The annual maps of wind patterns and PI-Matrix values show areas of both good and poor dispersion characteristics under the most prevalent flow conditions.

    To perform acoustic analysis of swallowing sounds, using a microphone and a notebook computer system, in healthy subjects and patients with dysphagia affected by neurological diseases, testing the positive/negative predictive value of a pathological pattern of swallowing sounds for penetration/aspiration. Diagnostic test study, prospective, not blinded, with the penetration/aspiration evaluated by fibreoptic endoscopy of swallowing as criterion standard. Data from a previously recorded database of normal swallowing sounds for 60 healthy subjects according to gender, age, and bolus consistency was compared with those of 15 patients with dysphagia from a university hospital referral centre who were affected by various neurological diseases. Mean duration of the swallowing sounds and post-swallowing apnoea were recorded. Penetration/aspiration was verified by fibreoptic endoscopy of swallowing in all patients with dysphagia. The mean duration of swallowing sounds for a liquid bolus of 10 ml water was significantly different between patients with dysphagia and healthy patients. We also described patterns of swallowing sounds and tested the negative/positive predictive values of post-swallowing apnoea for penetration/aspiration verified by fibreoptic endoscopy of swallowing (sensitivity 0.67 (95% confidence interval 0.24-0.94); specificity 1.00 (95% confidence interval 0.56-1.00)). The proposed technique for recording and measuring swallowing sounds could be incorporated into the bedside evaluation, but it should not replace the use of more diagnostic and valuable measures.

    A self-administered pain assessment tool called the Pain-O-Meter (POM) was developed for the purposes of improving assessment and management of pain in acute and chronic pain patients. The POM is a hard, white, plastic tool that measures 8-in. long by 2-in. wide and 1-in. thick. Two methods for assessing pain are located on the POM. The first is a 10-cm visual analogue scale (POM-VAS) with a moveable marker that patients use to rate their pain. The second is a list of 15 sensory and 11 affective word descriptors (WDS). Each WDS is assigned an intensity value that can be as low as 1 or as high as 5. A pain intensity score is provided for the sensory and the affective WDSs. This psychometric study, which employed correlational and comparative designs, investigated the test-retest reliability and the concurrent and construct validity of the POM-VAS and the POM-WDS in 279 patients with acute or chronic pain. High correlations were found between initial and repeat pain intensity ratings on the POM-VAS (r = 0.88, P evaluation of pain relief measures.

    Full Text Available Background: Hypoglycemia is common in type 1 diabetes, but the overall frequency of both mild and severe hypoglycemia is difficult to estimate. The Hypoglycemia Fear Survey II (HFS-II is often used to assess the fear of hypoglycemia. Material and methods: The aim of this study was to assess the psychometric properties of the Norwegian version of the HFS-II for adults, including the behavior (HFS-B and worry (HFS-W subscales, among 235 adults in Norway with type 1 diabetes. We assessed associations between HFS-II scores and other rating scales and demographic and clinical variables. Results: The Norwegian version of HFS-II had an acceptable factor structure in relation to HFS-W, whereas the structure within HFS-B was more questionable. The expected relationships between HFS-II subscales and measures of related constructs administered concurrently demonstrated adequate convergent and discriminant validity. Internal consistency and test-retest reliability were satisfactory. Conclusion: Access to reliable and valid self-report instruments enables the early detection of psychosocial problems. HFS-W performs well, whereas HFS-B needs to be further examined and developed.

    Full Text Available Abstract Background The Agency for Healthcare Research and Quality (AHRQ Hospital Survey on Patient Safety Culture was designed to assess staff views on patient safety culture in hospital settings. The purpose of this study was to examine the multilevel psychometric properties of the survey. Methods Survey data from 331 U.S. hospitals with 2,267 hospital units and 50,513 respondents were analyzed to examine the psychometric properties of the survey's items and composites. Item factor loadings, intraclass correlations (ICCs, design effects, internal consistency reliabilities, and multilevel confirmatory factor analyses (MCFA were examined as well as intercorrelations among the survey's composites. Results Psychometric analyses confirmed the multilevel nature of the data at the individual, unit and hospital levels of analysis. Results provided overall evidence supporting the 12 dimensions and 42 items included in the AHRQ Hospital Survey on Patient Safety Culture as having acceptable psychometric properties at all levels of analysis, with a few exceptions. The Staffing composite fell slightly below cutoffs in a number of areas, but is conceptually important given its impact on patient safety. In addition, one hospital-level model fit indicator for the Supervisor/Manager Expectations & Actions Promoting Patient Safety composite was low (CFI = .82, but all other psychometrics for this scale were good. Average dimension intercorrelations were moderate at .42 at the individual level, .50 at the unit level, and .56 at the hospital level. Conclusions Psychometric analyses conducted on a very large database of hospitals provided overall support for the patient safety culture dimensions and items included in the AHRQ Hospital Survey on Patient Safety Culture. The survey's items and dimensions overall are psychometrically sound at the individual, unit, and hospital levels of analysis and can be used by researchers and hospitals interested in assessing

    Neonatal intensive care units (NICUs) are a high-risk setting. The Safety Attitude Questionnaire (SAQ) is a widely used tool to measure safety culture. The aims of the study are to verify the psychometric properties of the Italian version of SAQ, to evaluate safety culture in the NICUs and to identify improvement interventions. A cross-sectional study was conducted in 6 level III NICUs. The SAQ was translated into Italian and adapted to the context, a confirmatory factor analysis (CFA) was performed to validate the questionnaire. 193 questionnaires were collected. The mean response rate was 59.7% (range 44.5%-95.7%). The answers were analysed according to six factors: f1 - teamwork climate, f2 - safety climate, f3 - job satisfaction, f4 - stress recognition, f5 - perception of management, f6 - working conditions. The CFA indexes were adequate (McDonald's omega indexes varied from 0.74 to 0.94, the SRMR index was equal to 0.79 and the RMSEA index was 0.070, 95% CI = 0.063-0.078). The mean composite score was 57.6 (SD 17.9), ranging between 42.3 and 69.7 on a standardized 100-point scale. We highlighted significant differences among units and professions (P tool to evaluate and compare the safety culture in the NICUs.

    Background and aims Oral Health Related Quality of Life (OHRQoL) represents a multidimensional structure, being measured by complex instruments, such as the Oral Health Impact Profile (OHIP). The aim of this present study is to develop and test the psychometric properties of an initial Romanian (OHIP-49Ro) version. Methods The original OHIP-49 version was translated using a forward-backward technique into the Romanian OHIP-49Ro, which was applied in an interview form to 150 patients of the Second Medical Clinique of Internal Medicine, Cluj-Napoca. Confirmatory Factor Analysis (CFA) was applied, in order to evaluate the factor structure and construct validity of the OHIP-49Ro. Results The correlations between the OHIP-49Ro subscales were all positive and statistically significant. Cronbach’s Alpha coefficients values are above 0.7 for all subscales, providing support for the internal consistency of OHIP-49Ro scale scores. Regarding the CFA, for the seven factor model, the Bentler scaled chi-square (S–Bχ2) indicated a value of 2193.74 (df=1091; p=0.001), the CFI a value of 0.740, the TLI a value of 0.72 and RMSEA the value of 0.82. Conclusions The results of this study suggest a high internal consistency of the OHIP-49Ro instrument. Due to the correlations between several sets of factors, and the multiple-factorial load for several items, the OHIP-49Ro’s factorial structure requires further research on different samples and in different cultural and educational contexts.

    Full Text Available Studies show a high prevalence of vocal alterations among teachers. One of the criteria for the establishment of the prevalence of vocal alteration is based on teachers' self-perception. Objective: This study aimed at comparing voice-disordered quality of life measures between a group of teachers who reported vocal alteration and a group of teachers who did not, by verifying the teachers' perception regarding the impact of vocal alteration in the different dimensions of voice quality of life. Material and Methods: Ninety-seven (97 teachers answered three psychometric protocols of voice quality of life: Voice Handicap Index (VHI, Voice-Related Quality of Life (V-RQOL, and the Voice Activity Participation Profile (VAPP, in addition to a questionnaire for characterization of the sample. Results: The results were that 39.8% of the teachers reported vocal alteration. When comparing voice measures between the groups (with and without vocal alteration, statistically significant differences were observed: the total score of VHI, total score of V-RQOL and total score of VAAP and its dimensions. It was also verified that the physical dimension of VHI has a greater impact among the dimensions of this protocol. For VRQOL, the most striking dimension was the physical functioning domain, both indicating the laryngeal discomfort and the impact of voice on communication, in teachers with and without complaints. As for VAAP, no domain prevailed over the others in the group with no complaints. For teachers with complaints, three domains, i.e., daily communication, work, and emotions have a greater impact than social communication. The limitation and restriction scores were calculated as well, and it was observed the limitation of activities is greater than the restriction of activities, both in the group with and the group without complaints. Conclusion: One may conclude that the teachers who reported vocal alterations better realize the impact of voice in

By using a facet theoretical approach and based on literature as well as on clinical experience, a 20-item Pathological Buying Screener (PBS was developed and administered to a representative German sample (n = 2,539. Valid data were available from 2,403 participants who were subjects for three subsequent empirical studies. The first study explored the factor structure using exploratory factor analyses in a subsample of 498 participants. Based on factor loadings, a 13-item version with the two factors loss of control / consequences and excessive buying behavior was revealed. This two-factor model was confirmed in study 2 by confirmatory factor analysis performed on another subsample (n = 1,905. Study 3 investigated age and gender effects and convergent validity of the PBS using the Compulsive Buying Scale (CBS in the full sample (N = 2,403. The total PBS score was adequately correlated with the CBS score. Hierarchical regression analyses with the CBS score as the dependent variable and the two PBS factors as the predictors indicated an own incremental validity of the two factors in participants ≤ 65 years. The reliability of the total score as well as of the two subscales was good to excellent. Overall, the PBS represents a useful measure for PB. Future studies are needed to replicate the two-factor structure in clinical samples and to define a valid cutoff for PB.

    The study was designed to develop a new screening instrument for pathological buying (PB), and to examine its psychometric properties in a large-scale sample. By using a facet theoretical approach and based on literature as well as on clinical experience, a 20-item Pathological Buying Screener (PBS) was developed and administered to a representative German sample (n = 2,539). Valid data were available from 2,403 participants who were subjects for three subsequent empirical studies. The first study explored the factor structure using exploratory factor analyses in a subsample of 498 participants. Based on factor loadings, a 13-item version with the two factors loss of control / consequences and excessive buying behavior was revealed.

    Full Text Available Abstract Background The Patient Assessment of Chronic Illness Care (PACIC is a US measure of chronic illness quality of care, based on the influential Chronic Care Model (CCM. It measures a number of aspects of care, including patient activation; delivery system design and decision support; goal setting and tailoring; problem-solving and contextual counselling; follow-up and coordination. Although there is developing evidence of the utility of the scale, there is little evidence about its performance in the United Kingdom (UK. We present preliminary data on the psychometric performance of the PACIC in a large sample of UK patients with long-term conditions. Method We collected PACIC, demographic, clinical and quality of care data from patients with long-term conditions across 38 general practices, as part of a wider longitudinal study. We assess rates of missing data, present descriptive and distributional data, assess internal consistency, and test validity through confirmatory factor analysis, and through associations between PACIC scores, patient characteristics and related measures. Results There was evidence that rates of missing data were high on PACIC (9.6% - 15.9%, and higher than on other scales used in the same survey. Most PACIC sub-scales showed reasonable levels of internal consistency (alpha = 0.68 – 0.94, responses did not demonstrate high skewness levels, and floor effects were more frequent (up to 30.4% on the follow up and co-ordination subscale than ceiling effects (generally Conclusion The importance of improving care for long-term conditions means that the development and validation of measures is a priority. The PACIC scale has demonstrated potential utility in this regard, but further assessment is required to assess low levels of completion of the scale, and to explore the performance of the scale in predicting outcomes and assessing the effects of interventions.

    The Attention-Distraction, Inhibition-Excitation Classroom Assessment Scale (ADIECAS) [Evans, P. L. C. (1975). Inhibition and stimulus generalization in the discrimination learning of ESN(S) and ESN(M) children. Unpublished Ph.D. thesis. Manchester, UK: University of Manchester] assesses attention-related difficulties in children with intellectual disabilities (ID). The present study explored the psychometric properties of the ADIECAS with a sample of 84 children with moderate and severe ID whose teachers completed the ADIECAS and the Conners' Teachers Rating Scale [Goyette, C. H, Conners, C. K., & Ulrich, R. F. (1978). Normative data on revised Conners' parent and teachers rating scales. Journal of Abnormal Child Psychology, 6, 221-236]. Following factor analysis the Evans and Hogg [Evans, P. L. C., & Hogg, J. (1984). A classroom rating scale for use with mentally retarded children. British Journal of Clinical Psychology, 23, 187-194] structure was the most appropriate for use with this sample. Moderate to strong positive relationships were found between the ADIECAS and the Conners', and the ADIECAS factors were significant predictors of the Conners' subscales. This study provides further support for the ADIECAS as a reliable and valid measure of ADHD-related symptoms among children with moderate and severe ID.

    Logical grammatical structures comprehension is the ability to understand the relations between objects, actions, and qualities in spoken and written sentences. The Logical Grammatical Structures Test (LGST) was especially devised to assess these abilities in children and adolescents. In the present study the LGST was administered to 405 healthy Dutch children and adolescents. The aims of the present study were (i) to evaluate the psychometric properties of the LGST (using an Item Response Theory framework), and (ii) to establish demographically corrected normative data. The results showed that there was a strong curvilinear relationship between age and LGST performance, i.e., the relative improvement in ability level was much more pronounced for younger children (aged below 14 years) than for older children (aged above 14 years). Level of parental education was positively associated with the LGST performance. Normative data that took the relevant demographic variables into account were established, and it was shown that the LGST had sound psychometric properties.

    This paper describes the development and psychometric evaluation of the symptoms and functioning severity scale (SFSS), which includes three parallel forms to systematically capture clinician, youth, and caregiver perspectives of youth symptoms on a frequent basis. While there is widespread consensus that different raters of youth psychopathology vary significantly in their assessment, this is the first paper that specifically investigated the discrepancies among clinician, youth, and caregiver ratings throughout the treatment process within a community mental health setting. Results for all three respondent versions indicated the SFSS is a psychometrically sound instrument for use in this population. Significant discrepancies in scores existed at baseline among the three respondents. Longitudinal analyses reveal the youth-clinician and caregiver-clinician score discrepancies decreased significantly over time. Differences by youth gender existed for caregiver-clinician discrepancies. The average youth-caregiver score discrepancy remained consistent throughout treatment. Implications for future research and clinical practice are discussed.

    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 Screenphiv, a screening measure for psychological issues related to HIV, was psychometrically tested in a study involving 744 HIV-infected people in Spain. Participants ages 18-82 (M = 43.04, 72 % men, 28 % women) completed an assessment protocol that included the Screenphiv and the MOS-HIV. A trained interviewer also collected relevant illness-related clinical data and socio-demographics from the participants. A confirmatory factor analysis was used to evaluate the goodness of fit of the Screenphiv's theoretical model and confirmed six first-order factors and two second-order factors [RMSEA (IC 90 %) = 0.07 (0.07-0.08)]. No floor or ceiling effects were observed for the scores. Cronbach's alphas were acceptable for all of the factors (from 0.65 to 0.92). Criterion-related validity also achieved; Screenphiv scores were related to socio-demographic and clinical variables and MOS-HIV summary scores. The Screenphiv is a reliable and valid measure, ready to use in research and clinical settings in Spain.

    The evaluation of sound localization accuracy (SLA) requires precise behavioral responses from the listener. Such responses are not always possible to elicit in infants and young children, and procedures for the assessment of SLA are time consuming. The aim of this study was to develop a fast, valid, and objective method for the assessment of SLA from 6 months of age. To this end, pupil positions toward spatially distributed continuous auditory and visual stimuli were recorded. Twelve children (29 to 157 weeks of age) who passed the universal newborn hearing screening and eight adults (18 to 40 years of age) who had pure-tone thresholds ≤20 dB HL in both ears participated in this study. Horizontal SLA was measured in a sound field with 12 loudspeaker/display (LD)-pairs placed in an audiological test room at 10 degrees intervals in the frontal horizontal plane (±55 degrees azimuth). An ongoing auditory-visual stimulus was presented at 63 dB SPL(A) and shifted to randomized loudspeakers simultaneously with pauses of the visual stimulus. The visual stimulus was automatically reintroduced at the azimuth of the sounding loudspeaker after a sound-only period of 1.6 sec. A corneal-reflection eye-tracking technique allowed the acquisition of the subjects' pupil positions relative to the LD-pairs. The perceived azimuth was defined as the median of the intersections between gaze and LD-pairs during the final 500 msec of the sound-only period. Overall SLA was quantified by an Error Index (EI), where EI = 0 corresponded to perfect match between perceived and presented azimuths, whereas EI = 1 corresponded to chance. SLA was rapidly measured in children (mean = 168 sec, n = 12) and adults (mean = 162 sec, n = 8). Visual inspection of gaze data indicated that gaze shifts occurred in sound-only periods. The medians of the perceived sound-source azimuths either coincided with the presenting sound-source azimuth or were offset by a maximum of 20 degrees in children. In contrast

    This study evaluates the psychometric performance of the Japanese version of the Overall Assessment of the Speaker's Experience of Stuttering for Adults (OASES-A), a comprehensive assessment tool of individuals who stutter. The OASES-A-J was administered to 200 adults who stutter in Japan. All respondents also evaluated their own speech (SA scale), satisfaction of their own speech (SS scale) and the Japanese translation version of the Modified Erickson Communication Attitude scale (S-24). The test-retest reliability and internal consistency of the OASES-A-J were assessed. To examine the concurrent validity of the questionnaire, Pearson correlation was conducted between the OASES-A-J Impact score and the S-24 scale, SA scale and SS scale. In addition, Pearson correlation among the impact scores of each section and total were calculated to examine the construct validity. The OASES-A-J showed a good test-retest reliability (r=0.81-0.95) and high internal consistency (α>0.80). Concurrent validity was moderate to high (0.55-0.75). Construct validity was confirmed by the relation between internal consistency in each section and correlation among sections' impact scores. Japanese adults showed higher negative impact for 'General Information', 'Reactions to Stuttering' and 'Quality of Life' sections. These results suggest that the OASES-A-J is a reliable and valid instrument to measure the impact of stuttering on Japanese adults who stutter. The OASES-A-J could be used as a clinical tool in Japanese stuttering field. Copyright © 2016 Elsevier Inc. All rights reserved.

    2017-02-01

    The Youth Anxiety Measure for DSM-5 (YAM-5) is a new self- and parent-report questionnaire to assess anxiety disorder symptoms in children and adolescents in terms of the contemporary classification system. International panels of childhood anxiety researchers and clinicians were used to construct a scale consisting of two parts: part one consists of 28 items and measures the major anxiety disorders including separation anxiety disorder, selective mutism, social anxiety disorder, panic disorder, and generalized anxiety disorder, whereas part two contains 22 items that focus on specific phobias and (given its overlap with situational phobias) agoraphobia. In general, the face validity of the new scale was good; most of its items were successfully linked to the intended anxiety disorders. Notable exceptions were the selective mutism items, which were frequently considered as symptoms of social anxiety disorder, and some specific phobia items especially of the natural environment, situational and other type, that were regularly assigned to an incorrect category. A preliminary investigation of the YAM-5 in non-clinical (N = 132) and clinically referred (N = 64) children and adolescents indicated that the measure was easy to complete by youngsters. In addition, support was found for the psychometric qualities of the measure: that is, the internal consistency was good for both parts, as well as for most of the subscales, the parent-child agreement appeared satisfactory, and there was also evidence for the validity of the scale. The YAM-5 holds promise as a tool for assessing anxiety disorder symptoms in children and adolescents.

    To assess the psychometric properties of the behavioral indicators of pain scale (ESCID) when applied to a wide range of medical and surgical critical patients. A multicentre, prospective observational study was designed to validate a scale measuring instrument. Twenty Intensive Care Units of 14 hospitals belonging to the Spanish National Health System. A total of 286 mechanically ventilated, unable to self-report critically ill medical and surgical adult patients. Pain levels were measured by two independent evaluators simultaneously, using two scales: ESCID and the behavioral pain scale (BPS). Pain was observed before, during, and after two painful procedures (turning, tracheal suctioning) and one non-painful procedure. ESCID reliability was measured on the basis of internal consistency using the Cronbach-α coefficient. Inter-rater and intra-rater agreement were measured. The Spearman correlation coefficient was used to assess the correlation between ESCID and BPS. A total of 4386 observations were made in 286 patients (62% medical and 38% surgical). High correlation was found between ESCID and BPS (r=0.94-0.99; p<0.001), together with high intra-rater and inter-rater concordance. ESCID was internally reliable, with a Cronbach-α value of 0.85 (95%CI 0.81-0.88). Cronbach-α coefficients for ESCID domains were high: facial expression 0.87 (95%CI 0.84-0.89), calmness 0.84 (95%CI 0.81-0.87), muscle tone 0.80 (95%CI 0.75-0.84), compliance with mechanical ventilation 0.70 (95%CI 0.63-0.75) and consolability 0.85 (95%CI 0.81-0.88). ESCID is valid and reliable for measuring pain in mechanically ventilated unable to self-report medical and surgical critical care patients. CLINICALTRIALS.GOV: NCT01744717.

  10. Proximity sounding analysis for derechos and supercells: an assessment of similarities and differences

    Science.gov (United States)

    Doswell, Charles A.; Evans, Jeffry S.

    Proximity soundings (within 2 h and 167 km) of derechos (long-lived, widespread damaging convective windstorms) and supercells have been obtained. More than 65 derechos, accompanied by 115 proximity soundings, are identified during the years 1983 to 1993. The derechos have been divided into categories according to the synoptic situation: strong forcing (SF), weak forcing (WF), and "hybrid" cases (which are neither weakly nor strongly forced). Nearly 100 supercell proximity soundings have been found for the period 1998 to 2001, subdivided into nontornadic and tornadic supercells; tornadic supercells were further subdivided into those producing significant (>F1 rating) tornadoes and weak tornadoes (F0-F1 rating). WF derecho situations typically are characterized by warm, moist soundings with large convective available potential instability (CAPE) and relatively weak vertical wind shear. SF derechos usually have stronger wind shears, and cooler and less moist soundings with lower CAPE than the weakly forced cases. Most derechos exhibit strong storm-relative inflow at low levels. In WF derechos, this is usually the result of rapid convective system movement, whereas in SF derechos, storm-relative inflow at low levels is heavily influenced by relatively strong low-level windspeeds. "Hybrid" cases collectively are similar to an average of the SF and WF cases. Supercells occur in environments that are not all that dissimilar from those that produce SF derechos. It appears that some parameter combining instability and deep layer shear, such as the Energy-Helicity Index (EHI), can help discriminate between tornadic and nontornadic supercell situations. Soundings with significant tornadoes (F2 and greater) typically show high 0-1 km relative humidities, and strong 0-1 km shear. Results suggest it may not be easy to forecast the mode of severe thunderstorm activity (i.e., derecho versus supercell) on any particular day, given conditions that favor severe thunderstorm activity

    Culturally sensitive and valid assessments of participation in occupations are needed for Spanish-speaking children to enhance services offered to this population. The purpose of this study was to assess the validity and reliability of the newly developed Spanish version of the Children's Assessment of Participation and Enjoyment and Preferences for Activities of Children, the Evaluación de Participacion y Disfrute de los Niños y Preferencias de las Actividades de los Niños (EPDN/PAN). The sample included 249 children with and without disabilities, aged 6 to 15 years. Statistically significant differences (p < 0.05) in the participation of children with disabilities and children without disabilities, and between younger and older children were found. No statistical significant differences were found between males and females in the dimensions of participation assessed. Adequate internal consistency (0.70-0.92) was found for the PAN scale and the Overall and Informal domain scores of the EPDN-Intensity scale. Further study is needed to evaluate the formal domain scale and gender differences by activity types.

    A recent critique of Copping, Campbell, and Muncer raised several issues concerning the validity of psychometric assessment techniques in the study of life history (LH) strategies. In this reply, some of our key concerns about relying on aggregated psychometric measures are explained, and we raise questions generally regarding the use of higher order factor structures. Responses to some of the statistical issues raised by Figueredo et al. are also detailed. We stand by our original conclusions and call for more careful consideration of instruments used to evaluate hypotheses derived from LH theory.

    The Conformity to Feminine Norms Inventory-45 (CFNI-45; Parent & Moradi, 2010) is an important tool for assessing level of conformity to feminine gender norms and for investigating the implications of such norms for women's functioning. The authors of the present study assessed the factor structure, measurement invariance, reliability, and validity of the CFNI-45 with data from 520 college women (55% White). Confirmatory factor analyses with data from this sample suggested acceptable fit for the posited 9-factor structure. Furthermore, analyses of measurement invariance indicated similar structural properties with members of socioculturally dominant (i.e., White) and nondominant (i.e., women of color) racial/ethnic status groups. Also, subscales of the CFNI-45 demonstrated acceptable internal consistency reliability coefficients, and correlations with convergent and discriminant validity indicators supported the validity of subscales scores. Overall, results offered support for the CFNI-45 as a multidimensional measure of women's conformity to feminine norms. The CFNI-45 can be used in research to facilitate evaluation of the theorized roles of conformity to feminine norms in women's mental health, vocational behavior, interpersonal relationships, and other domains. The CFNI-45 can be used in clinical practice to assess and attend to clients' conformity to feminine norms as is called for in the American Psychological Association's (2007) Guidelines for Psychological Practice with Girls and Women.

    Altered interoceptive awareness (IA) has been implicated in the pathophysiology of eating disorders; however, few comprehensive self-report measures of IA exist in eating disorders. The present study sought to validate the Multidimensional Assessment of Interoceptive Awareness (MAIA), originally developed to assess IA in individuals practicing mind-body therapies, in an eating disorder sample. Adult and adolescent patients (n = 376) completed assessments upon admission to a partial hospital programme. Analyses examined the factor structure of the MAIA, scale means, scale-scale correlations, internal consistency and construct validity. Analyses also examined associations between MAIA subscales and eating disorder symptoms. Results supported the original eight-factor structure of the MAIA. Internal consistency was acceptable, and the scales converged with associated measures. Importantly, Not Distracting, Self-regulation, Body Listening and Trusting were most strongly associated with eating disorder symptoms. Results support use of the MAIA among eating disorders and provide further support for the relevance of IA in eating disorders.

    Full Text Available Abstract Background In the continuing revision of Diagnostic and Statistical Manual (DSM-V “identity” is integrated as a central diagnostic criterion for personality disorders (self-related personality functioning. According to Kernberg, identity diffusion is one of the core elements of borderline personality organization. As there is no elaborated self-rating inventory to assess identity development in healthy and disturbed adolescents, we developed the AIDA (Assessment of Identity Development in Adolescence questionnaire to assess this complex dimension, varying from “Identity Integration” to “Identity Diffusion”, in a broad and substructured way and evaluated its psychometric properties in a mixed school and clinical sample. Methods Test construction was deductive, referring to psychodynamic as well as social-cognitive theories, and led to a special item pool, with consideration for clarity and ease of comprehension. Participants were 305 students aged 12–18 attending a public school and 52 adolescent psychiatric inpatients and outpatients with diagnoses of personality disorders (N = 20 or other mental disorders (N = 32. Convergent validity was evaluated by covariations with personality development (JTCI 12–18 R scales, criterion validity by differences in identity development (AIDA scales between patients and controls. Results AIDA showed excellent total score (Diffusion: α = .94, scale (Discontinuity: α = .86; Incoherence: α = .92 and subscale (α = .73-.86 reliabilities. High levels of Discontinuity and Incoherence were associated with low levels in Self Directedness, an indicator of maladaptive personality functioning. Both AIDA scales were significantly different between PD-patients and controls with remarkable effect sizes (d of 2.17 and 1.94 standard deviations. Conclusion AIDA is a reliable and valid instrument to assess normal and disturbed identity in adolescents. Studies for further

    The UK Functional Assessment Measure (UKFIM+FAM) is the principal outcome measure for the UK Rehabilitation Outcomes Collaborative (UKROC) national database for specialist rehabilitation. Previously validated in a mixed neurorehabilitation cohort, this study is the first to explore its psychometric properties in a stroke population, and compare left and right hemispheric strokes (LHS vs RHS). We analysed in-patient episode data from 62 specialist rehabilitation units collated through the UKROC database 2010-2013. Complete data were analysed for 1,539 stroke patients (LHS: 588, RHS: 566 with clear localisation). For factor analysis, admission and discharge data were pooled and randomised into two equivalent samples; the first for exploratory factor analysis (EFA) using principal components analysis, and the second for confirmatory factor analysis (CFA). Responsiveness for each subject (change from admission to discharge) was examined using paired t-tests and differences between LHS and RHS for the entire group were examined using non-paired t-tests. EFA showed a strong general factor accounting for >48% of the total variance. A three-factor solution comprising motor, communication and psychosocial subscales, accounting for >69% total variance, provided acceptable fit statistics on CFA (Root Mean Square Error of Approximation was 0.08 and Comparative Fit Index/ Tucker Lewis Index 0.922/0.907). All three subscales showed significant improvement between admission and discharge (p0.5). Total scores between LHS and RHS were not significantly different. However, LHS showed significantly higher motor scores (Mean 5.7, 95%CI 2.7, 8.6 pstroke, similar to the general neurorehabilitation population. It is responsive to change during in-patient rehabilitation, and distinguishes between LHS and RHS. This tool extends stroke outcome measurement beyond physical disability to include cognitive, communication and psychosocial function.

    Cancer care is increasingly provided in the outpatient setting, requiring specific monitoring of care quality. The patients' perspective is an important indicator of care quality and needs to be assessed with well designed, psychometrically sound questionnaires. We performed a systematic literature review of currently available patient satisfaction measures for use in cancer outpatient care settings. We carried out MEDLINE/PubMed, PsycINFO, CINAHL, and Scopus searches of papers published over the past 15 years that describe cancer patient satisfaction questionnaires for use in the outpatient setting. We used the adapted COSMIN checklist to assess the quality of the questionnaires' measurement properties. A total of 6677 citations were identified and 76 relevant articles were read, of which 55 were found either not to be relevant or to provide insufficient psychometric information. The remaining 21 studies pertained to 14 patient satisfaction questionnaires. Continuity and transition, accessibility, and involvement of family/friends were less frequently addressed despite their relevance in outpatient oncology. Almost half of the psychometric studies did not provide information on item level missing data. Most internal consistency estimates (Cronbach's α) were satisfactory. Few studies reported test-retest assessment (n = 5), used confirmatory factor analysis (n = 2), or assessed fit to a graded response item response theory model (n = 3). Only three questionnaires were cross-culturally validated. Important aspects of care may be missed by current patient satisfaction questionnaires for use in the cancer outpatient setting. Additional evidence is needed of their psychometric performance, especially for cross-cultural comparative assessments. Copyright © 2014 John Wiley & Sons, Ltd.

    The Evidence-Based Practice Beliefs (EBP-B) and Evidence-Based Practice Implementation (EBP-I) scales are psychometrically sound instruments that were used, within an educational setting, to systematically study students' beliefs about and their implementation of evidence-based practice (EBP). Czech and Slovak versions of these instruments were developed and evaluated using a sample population of nursing students. The purpose of the study was to test the psychometric properties of the Czech and Slovak versions of the EBP-B and EBP-I scales. Psychometric properties were evaluated using a sample of undergraduate and graduate (nearly graduated) nursing students (n = 223) completing EBP courses. To test psychometric properties of the questionnaire, its reliability and validity were explored. Cronbach´s alpha was computed to evaluate internal structure and internal consistency. The Slovak versions of both the EBP-B and the EBP-I scale have good internal consistency (Cronbach's alpha: .82 and .94, respectively). Similarly, the Czech versions of the EBP-B and the EBP-I scales both have good internal consistency (Cronbach's alpha: .85 and .89, respectively). The results of psychometric analysis of the Czech and Slovak versions of the EBP-B and the EBP-I scales are consistent with the results of the original study and indicate that the Czech and Slovak versions have the potential to be valid, reliable, and sensitive instruments for measuring an individual's beliefs about the value of EBP and their ability to implement it. Both instruments can be used to assess changes in nurses´ beliefs about EBP over time as well as the effectiveness of strategies aimed at promoting the use of evidence in practice. © 2016 Sigma Theta Tau International.

  7. Assessing Acoustic Sound Levels Associated with Active Source Seismic Surveys in Shallow Marine Environments

    The potential effect of active source seismic research on marine mammal populations is a topic of increasing concern, and controversy surrounding such operations has begun to impact the planning and permitting of academic surveys [e.g., Malakoff, 2002 Science]. Although no causal relationship between marine mammal strandings and seismic exploration has been proven, any circumstantial evidence must be thoroughly investigated. A 2002 stranding of two beaked whales in the Gulf of California within 50 km of a R/V Ewing seismic survey has been a subject of concern for both marine seismologists and environmentalists. In order to better understand possible received levels for whales in the vicinity of these operations, modeling is combined with ground-truth calibration measurements. A wide-angle parabolic equation model, which is capable of including shear within the sediment and basement layers, is used to generate predictive models of low-frequency transmission loss within the Gulf of California. This work incorporates range-dependent bathymetry, sediment thickness, sound velocity structure and sub-bottom properties. Oceanic sounds speed profiles are derived from the U.S. Navy's seasonal GDEM model and sediment thicknesses are taken from NOAA's worldwide database. The spectral content of the Ewing's 20-airgun seismic array is constrained by field calibration in the spring of 2003 [Tolstoy et al., 2004 GRL], indicating peak energies at frequencies below a few hundred Hz, with energy spectral density showing an approximate power-law decrease at higher frequencies (being ~40 dB below peak at 1 kHz). Transmission loss is estimated along a series of radials extending from multiple positions along the ship's track, with the directivity of the array accounted for by phase-shifting point sources that are scaled by the cube root of the individual airgun volumes. This allows the time-space history of low-frequency received levels to be reconstructed within the Gulf of California

    To develop and psychometrically evaluate an audio digitised tool for assessment of comprehension of informed consent among low-literacy Gambian research participants. We conducted this study in the Gambia where a high illiteracy rate and absence of standardised writing formats of local languages pose major challenges for research participants to comprehend consent information. We developed a 34-item questionnaire to assess participants' comprehension of key elements of informed consent. The questionnaire was face validated and content validated by experienced researchers. To bypass the challenge of a lack of standardised writing formats, we audiorecorded the questionnaire in three major Gambian languages: Mandinka, Wolof and Fula. The questionnaire was further developed into an audio computer-assisted interview format. The digitised questionnaire was administered to 250 participants enrolled in two clinical trials in the urban and rural areas of the Gambia. One week after first administration, the questionnaire was readministered to half of the participants who were randomly selected. Participants were eligible if enrolled in the parent trials and could speak any of the three major Gambian languages. The primary outcome measure was reliability and validity of the questionnaire. Item reduction by factor analysis showed that 21 of the question items have strong factor loadings. These were retained along with five other items which were fundamental components of informed consent. The 26-item questionnaire has high internal consistency with a Cronbach's α of 0.73-0.79 and an intraclass correlation coefficient of 0.94 (95% CI 0.923 to 0.954). Hypotheses testing also showed that the questionnaire has a positive correlation with a similar questionnaire and discriminates between participants with and without education. We have developed a reliable and valid measure of comprehension of informed consent information for the Gambian context, which might be easily adapted to

    2008-01-01

    BACKGROUND There is growing interest in starting a program to sink ships in Puget Sound to create one or more underwater dive sites. Experience in other parts of the world has indicated that sunken vessels are highly popular with divers and could provide a basis for increased recreation and attraction of out-of-state divers with attendant economic benefits to the State. The Washington State legislature reviewed this possibility during the 2006 session and determined that more information is required before the legislature could determine if this activity is feasible or desirable. The legislature directed several State agencies to undertake a preliminary study of the feasibility. The Washington Department of Fish and Wildlife (WDFW, lead State agency) in turn asked U.S. Geological Survey to conduct the study.

    Full Text Available Orientation: Researchers need to assess the psychometric rigour of resilience measuring scales. Research purpose: The purpose of the study was to assess the psychometric properties of the South African Adult Resilience Indicator (ARI.Motivation for the study: Researchers have not previously published the psychometric properties of the South African Adult Resilience Indicator.Research design, approach and method: The authors used a cross-sectional quantitative research design. A sample of 789 young adults participated in the study. Cross-validation allowed the authors to confirm (using the validation sample the validity of the ARI structure they obtained during initial testing (using the calibration sample. They investigated two measurement models (the original factor structure and a one-dimensional factor structure.Main findings: The original factor structure presented the data and the proposed theory better than did the one-dimensional factor structure. The authors found acceptable goodness of fit for the ARI. More specifically, they found invariance (in terms of equal factor loadings,covariances and error variances in the calibration and validation samples. They also found acceptable reliability estimates for each of the eight sub-scales.Practical/managerial implications: The results can help researchers and practitioners interested in measuring resilience in adults to choose a resilience measure and to select an appropriate measure for their populations and contexts.Contribution/value-add: Previous research has clearly shown that reliable and valid resilience measures are necessary. It is also necessary to assess the psychometric properties of the currently available instruments and to publish the findings. This study has helped by examining the psychometric properties of the South African Adult Resilience Indicator.

    Full Text Available In the present study we devised scales for teachers’ and parents’ estimation of intellectual, creative and social abilities of fourth grade elementary school pupils. Their scores were related to psychometrically determined ability scores. Ninety-three school pupils in the age range between 9.3 and 11.2 years, as well as their parents and teachers took part. The new rating checklists proved as sufficiently reliable (particularly the teachers’ version. Analyses of validity showed a high correspondence in parents’ and teachers’ estimations of cognitive intelligence, but much lower correspondence for creativity and social ability. Correlating teachers’ and parents’ estimates with the respective psychometric tests shows that teachers and parents were better at identifying intellectual (highability than detecting creative and social abilities. With the exception of social (highability, where girls were usually regarded as highly socially gifted by their parents, there were no differences in parents’ and teachers’ estimations of boys and girls.

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.

    Directory of Open Access Journals (Sweden)

    2011-05-01

    Full Text Available Tobacco smoking is hazardous for health. However, not all forms of tobacco use entail the same risks and the latter should be studied and compared in a sound realistic way. Smoking machines for cigarettes (which are consumed in a few minutes were early designed as a tool to evaluate the actual intake of toxic substances (‘toxicants’ by smokers. However, the yields (tar, nicotine, CO, etc. provided by such machines poorly reflect the actual human smoking behaviour known to depend on numerous factors (anxiety, emotions, anthropological situation, etc.. In the case of narghile smoking, the problems are even more complex, particularly because of the much longer duration of a session. A recent study from the US-American University of Beirut was based on a field smoking topography and claimed consistency with a laboratory smoking machine. We offer a point by point critical analysis of such methods on which most of the ‘waterpipe’ antismoking literature since 2002 is based.

  19. Kurtosis corrected sound pressure level as a noise metric for risk assessment of occupational noises.

    Goley, G Steven; Song, Won Joon; Kim, Jay H

    2011-03-01

    Current noise guidelines use an energy-based noise metric to predict the risk of hearing loss, and thus ignore the effect of temporal characteristics of the noise. The practice is widely considered to underestimate the risk of a complex noise environment, where impulsive noises are embedded in a steady-state noise. A basic form for noise metrics is designed by combining the equivalent sound pressure level (SPL) and a temporal correction term defined as a function of kurtosis of the noise. Several noise metrics are developed by varying this basic form and evaluated utilizing existing chinchilla noise exposure data. It is shown that the kurtosis correction term significantly improves the correlation of the noise metric with the measured hearing losses in chinchillas. The average SPL of the frequency components of the noise that define the hearing loss with a kurtosis correction term is identified as the best noise metric among tested. One of the investigated metrics, the kurtosis-corrected A-weighted SPL, is applied to a human exposure study data as a preview of applying the metrics to human guidelines. The possibility of applying the noise metrics to human guidelines is discussed.

    Teaching and assessment of communication skills have become essential in medical education. The Objective Structured Clinical Examination (OSCE) has been found as an appropriate means to assess communication skills within medical education. Studies have demonstrated the importance of a valid assessment of medical students' communication skills. Yet, the validity of the performance scores depends fundamentally on the quality of the rating scales used in an OSCE. Thus, this systematic review aimed at providing an overview of existing rating scales, describing their underlying definition of communication skills, determining the methodological quality of psychometric studies and the quality of psychometric properties of the identified rating scales. We conducted a systematic review to identify psychometrically tested rating scales, which have been applied in OSCE settings to assess communication skills of medical students. Our search strategy comprised three databases (EMBASE, PsycINFO, and PubMed), reference tracking and consultation of experts. We included studies that reported psychometric properties of communication skills assessment rating scales used in OSCEs by examiners only. The methodological quality of included studies was assessed using the COnsensus based Standards for the selection of health status Measurement INstruments (COSMIN) checklist. The quality of psychometric properties was evaluated using the quality criteria of Terwee and colleagues. Data of twelve studies reporting on eight rating scales on communication skills assessment in OSCEs were included. Five of eight rating scales were explicitly developed based on a specific definition of communication skills. The methodological quality of studies was mainly poor. The psychometric quality of the eight rating scales was mainly intermediate. Our results reveal that future psychometric evaluation studies focusing on improving the methodological quality are needed in order to yield psychometrically

    2017-06-01

    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.

    Schweizer, C. Amanda; Doran, Neal; Myers, Mark G.

    2014-01-01

    Objective Expectancies about social outcomes for smoking are relevant to college student smokers, who frequently report “social smoking.” A new measure, the Social Facilitation Expectancies (SFE) scale, was developed to assess these beliefs. Participants The SFE was administered to undergraduate college student smokers (N=1096; study completed in May 2011). Methods Items were scored on a five-point scale with a summed total score. The sample was randomly split and principle axis factoring and confirmatory factor analysis applied to determine scale structure. The structure was tested across sex and smoking groups and validation analyses were conducted. Results A nine-item, one-factor scale was replicated within each group. Higher SFE scores were observed among those with greater smoking experience and higher scores were associated with greater endorsement of other smoking related beliefs. Conclusions These preliminary findings provide support for the sound psychometric properties of this measure for use with young adult college students. PMID:24456515

    Identifying the function of behavior is crucial in formulating functionally-based treatment programs for people with challenging behaviors. The Questions About Behavior Function (QABF) is a well-established instrument with sound psychometric properties. The present study describes the development process for a Korean version of the QABF. The factor structure was examined in a sample of 153 QABF-K assessments, which yielded a five-factor-solution identical to the original English version. In terms of reliability, internal consistency was good with Chronbach's alpha ranging from 0.80 to 0.87 and test-retest reliability was found to be good with correlation coefficients ranging from 0.73 to 0.91. Based upon the present results, the QABF-K appears to be a promising tool for use with informants whose primary language is Korean.

    2016-01-01

    This study examined the psychometric properties of the Child Adjustment and Parent Efficacy Scale-Developmental Disability (CAPES-DD), a brief inventory for assessing emotional and behavioral problems of children with developmental disabilities aged 2- to 16-years, as well as caregivers' self-efficacy in managing these problems. A sample of 636 parents participated in the study. Children's ages ranged from 2 to 15. Exploratory and confirmatory factor analyses supported a 21-item, three-factor model of CAPES-DD child adjustment with 13 items describing behavioral (10 items) and emotional (3 items) problems and 8 items describing prosocial behavior. Three additional items were included due to their clinical usefulness and contributed to a Total Problem Score. Factor analyses also supported a 16-item, one factor model of CAPES-DD self-efficacy. Psychometric evaluation of the CAPES-DD revealed scales had satisfactory to very good internal consistency, as well as very good convergent and predictive validity. The instrument is to be in the public domain and free for practitioners and researchers to use. Potential uses of the measure and implications for future validation studies are discussed.

    An understanding of health-related quality of life (HRQOL) is of utmost importance in both oncological and esthetic breast surgery. The BREAST-Q is a patient-reported outcome (PRO) measure that investigates HRQOL and patient satisfaction before and after breast surgery. The aim of this study was to develop a Japanese version of the BREAST-Q including the mastectomy module, the reconstruction module, the augmentation module and the reduction/mastopexy module, and to assess the psychometric properties of the mastectomy module among Japanese women. The Japanese version of the BREAST-Q was developed through forward translation, backward translation and patient testing. Traditional psychometric testing of the mastectomy module was administered to 45 post-mastectomy patients. The mastectomy, reconstruction, augmentation and reduction/mastopexy modules were formally developed into Japanese. Despite cultural difference between Japanese women and original target population, the contents were considered to be valid among Japanese woman. With the exception of the sexual well-being subscale, good reliability and validity were evident for the mastectomy module (Test-retest reliability 0.76-0.95, Chronbach's alpha coefficient 0.77-0.98). The BREAST-Q Japanese version is a useful PRO measure for investigating the impact of breast surgery on HRQOL and patient satisfaction. Further validation in younger Japanese women is needed to determine the usefulness of the sexual well-being subscale.

    As part of an ongoing study co-funded by the Bonneville Power Administration, under its Technology Innovation Grant Program, and the U.S. Department of Energy, the Pacific Northwest National Laboratory (PNNL) has developed an approach and modeling tool for assessing the net benefits of using energy storage located close to the customer in the distribution grid to manage demand. PNNL in collaboration with PSE and Primus Power has evaluated the net benefits of placing a zinc bromide battery system at two locations in the PSE system (Baker River / Rockport and Bainbridge Island). Energy storage can provide a number of benefits to the utility through the increased flexibility it provides to the grid system. Applications evaluated in the assessment include capacity value, balancing services, arbitrage, distribution deferral and outage mitigation. This report outlines the methodology developed for this study and Phase I results.

    Governance silos are settings in which different organizations work in isolation and avoid sharing information and strategies. Siloes are a fundamental challenge for environmental planning and problem solving, which generally requires collaboration. Siloes can be overcome by creating governance networks. Studying the structure and function of these networks is important for understanding how to create institutional arrangements that can respond to the biophysical dynamics of a specific natural resource system (i.e., social-ecological, or institutional fit). Using the case of salmon restoration in a sub-basin of Puget Sound, USA, we assess network integration, considering three different reasons for network collaborations (i.e., mandated, funded, and shared interest relationships) and analyze how these different collaboration types relate to productivity based on practitioner's assessments. We also illustrate how specific and targeted network interventions might enhance the network. To do so, we use a mixed methods approach that combines quantitative social network analysis (SNA) and qualitative interview analysis. Overall, the sub-basin's governance network is fairly well integrated, but several concerning gaps exist. Funded, mandated, and shared interest relationships lead to different network patterns. Mandated relationships are associated with lower productivity than shared interest relationships, highlighting the benefit of genuine collaboration in collaborative watershed governance. Lastly, quantitative and qualitative data comparisons strengthen recent calls to incorporate geographic space and the role of individual actors versus organizational culture into natural resource governance research using SNA.

    When an adolescent has chronic pain many aspects of a parent's life can be affected, including their emotional and social functioning. The assessment of this multidimensional parental impact is an essential, yet often neglected, clinical task. This study reports on the development and psychometric evaluation of the Bath Adolescent Pain--Parental Impact Questionnaire (BAP-PIQ), an assessment tool comprising multiple scales thought to be relevant for better understanding changes in functioning and behavior associated with parenting an adolescent with chronic pain. A sample of 194 parents of adolescents with chronic pain, recruited from three UK clinics, completed the 94 item draft inventory. Frequency and item correlation analyses resulted in a final inventory of 62 items. Internal consistency of all eight scales was established based on Cronbach's alpha. Convergent validity was undertaken by comparison of individual scales with existing validated measures of parental stress, mood, parenting behavior, marital adjustment, and general functioning. The temporal reliability of each scale was established using a sub-sample of 46 participants over a 14-day period. Psychometric evaluation suggests that the inventory yields a reliable and valid assessment of the multiple impacts of parenting an adolescent with chronic pain. The BAP-PIQ may offer a comprehensive assessment of these impacts in both a research and a clinical setting. Further study of the validity of BAP-PIQ scales and their ability to detect clinically meaningful change would be of use. Additional data from samples comprising fathers of adolescents with chronic pain and parents of adolescents with non-musculoskeletal pain would be of benefit.

    Anxiety has negative effects on the cognitive performance and psychosocial adjustment of elderly people. Given the high prevalence of anxiety symptoms in patients suffering from cognitive impairment, it has been suggested that these symptoms may be an early marker of dementia. The State-Trait Anxiety Inventory (STAI) is one of the most widely-used scales for evaluating anxiety in elderly people. However, inasmuch as the STAI may be difficult to apply to older people, having a short form of it would be desirable. The participants comprised 489 community-dwelling individuals aged 68 years and over. All of them were volunteers in a longitudinal study for early detection of Alzheimer' Disease (Proyecto Vallecas). The full sample was divided in two homogeneous subgroups: Group A, used to reduce the number of items and response options, and Group B, the group used to determine the psychometric properties of the new short form (STAIr). A dichotomous Rasch model was used to obtain the STAIr. No statistically significant differences for STAIr scores were found with respect to sociodemographic variables. Psychometric properties and normative data were obtained for the new short version. The STAIr is composed of 13 items and data fits the model well. Since it is short and easy to apply to elderly people, STAIr will be very useful in clinical and research settings. Copyright © 2013 Sociedad Española de Neurología.

    Full Text Available Reciprocity, a core component of social capital, is rarely theorized or measured leaving the relationship between reciprocity and health ambiguous. Historically, reciprocity measures have not been used in the context they were designed causing measurement error. This multi-phased study was designed to develop and validate a reciprocity measure for formal and informal groups within communities and congregations as part of a more comprehensive social capital measure. In-depth interviews (n = 72, cognitive interviews (n = 40, and an expert review panel guided item development and selection for content validity. South Carolina residents (n = 500 completed the 10-item Reciprocity of Social Support (RSS Scale during 2008-2010. Construct validity was supported through an exploratory factor analysis (EFA that confirmed a two-factor model for the scale for community- and congregation-based groups. Cronbach’s α values indicated items were highly correlated for community groups and church groups. Psychometric analyses of the RSS Scale support convergent and divergent validity for the community- and congregation-based groups. Mean RSS Scale scores were not statistically different between community- and congregation-based groups. This scale has proven psychometric properties for utilization in future research investigating reciprocity of social support in community- and congregation-based groups and will be useful to examine whether reciprocity (by context and type of group is associated with physical and/or mental health.

    2007-04-01

    A crucial problem in studies involving food cravings is the lack of a psychometrically sound measure for use among overweight and obese populations. The degree to which the Food Cravings Questionnaires-Trait (FCQ-T) and State (FCQ-S) evidenced acceptable psychometric properties among overweight and obese participants was assessed. In study 1, 109 participants completed the FCQ-T and FCQ-S. Item-total correlations, test-retest reliability, internal consistency, and factor structures were examined. Results indicate good internal consistency and partially support the factor structures. In study 2, the construct and predictive validity of the FCQ-S were examined. Twenty-eight women completed the FCQ-S 15 min after finishing a standardized breakfast and then twice more, 90 min apart. Subsequent ad libitum food intake was recorded. Results suggest that the FCQ-S is sensitive to state changes in food cravings, but that the magnitude of the changes was moderate. The FCQ-S was not a good predictor of subsequent food intake. The FCQ-T and FCQ-S may be useful in studies that examine triggers of and interventions for excessive food intake.

    The Satisfaction With Life Scale (SWLS) is a global measure of life satisfaction (LS). The objective of this study was to evaluate the psychometric properties (data completeness, scaling assumptions, targeting and reliability) of the SWLS in a sample of people with Parkinson's disease (PD). A postal survey including a Swedish version of the SWLS and demographic information was administered to 174 persons with PD; 97 responded and received a second survey after 2 weeks. The mean (SD) age and PD duration of the 97 responders were 73 (8) and 7 (6) years, respectively. Data completeness was 92% to 97% for the five items in the SWLS and 92% for the total score (5-35 points). The mean score of the SWLS was 24.2 points (7.7), indicating that this group had an average LS. The items' means and SDs were roughly parallel and the score distribution was even. The internal consistency reliability (Cronbach's alpha) was 0.90. The test-retest reliability, assessed by the intraclass correlation coefficient, was 0.78. The scale showed no systematic difference between the first and second response. The standard error of measurement was 3.6 points, and the smallest detectable difference was 10.0 points. This evaluation of the psychometric properties of the SWLS shows that the scale has good data completeness, scaling assumptions and targeting and that the internal consistency reliability and the test-retest reliability are acceptable. Thus, the SWLS is a psychometrically sound and suitable tool to asses LS in people with PD. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Investigating the impact of "off-line" cognitive structures on the broad range of antisocial behaviors shown by young people has been hampered by the absence of psychometrically robust measures of antisocial cognitions. This study evaluates the psychometric properties of the Antisocial Beliefs and Attitudes Scale (ABAS), a developmentally sensitive measure of young people's beliefs and attitudes toward social standards of acceptable behavior at home and at school. The reliability and validity of the ABAS was assessed in a sample of British school children (N = 486) aged 9-16 years (M = 12.79, SD = 1.90) and male young offenders (N = 84) aged 13-17 years (M = 15.15, SD = 0.27). Participants completed the ABAS, together with a self-report measure of antisocial behavior; maternal reports of antisocial activity were also collected in the offending sample. Confirmatory factor analysis replicated the 2-factor structure of Rule Noncompliance and Peer Conflict previously derived from a sample of Canadian school children, and these factors showed good test-retest reliability. Rule Noncompliance predicted self-reported antisocial behavior for ages 11-16 years, while Peer Conflict predicted antisocial behavior for ages 9-16 years. Comparisons between young offenders and an age-matched subsample of males from the school group showed significant differences. In young offenders, Rule Noncompliance and Peer Conflict were significantly predictive of self-reported antisocial behavior, while Rule Noncompliance independently predicted mothers' ratings of their sons' antisocial behavior. These findings provide support for the ABAS as a psychometrically sound measure of antisocial thinking.

    In the event of a natural or anthropogenic disturbance, environmental resource managers require a reliable tool to quickly assess the spatial extent of potential damage to the seagrass resource. The temporal availability of the Landsat 5 Thematic Mapper (TM) imagery provided a suitable option to detect and assess damage of the submerged aquatic vegetation (SAV). This study examined Landsat TM imagery classification techniques to create two-class (SAV presence/absence) and three-class (SAV estimated coverage) SAV maps of the seagrass resource. The Mahalanobis Distance method achieved the highest overall accuracy (86%) and validation accuracy (68%) for delineating the seagrass resource (two-class SAV map). The Maximum Likelihood method achieved the highest overall accuracy (74%) and validation accuracy (70%) for delineating the seagrass resource three-class SAV map. The Landsat 5 TM imagery classification provided a seagrass resource map product with similar accuracy to the aerial photointerpretation maps (validation accuracy 71%). The results support the application of remote sensing methods to analyze the spatial extent of the seagrass resource.

    Full Text Available Health literacy refers to personal competencies for the access to, understanding of, appraisal of and application of health information in order to make sound decisions in everyday life. The aim of this study was to develop and evaluate the psychometric properties of an instrument for the measurement of health literacy among adolescents (the Health Literacy Measure for Adolescents-HELMA.This study was made up of two phases, qualitative and quantitative, which were carried out in 2012-2014 in Tehran, Iran. In the qualitative part of the study, in-depth interviews with 67 adolescents aged 15-18 were carried out in 4 high schools to generate the initial item pool for the survey. The content validity of the items was then assessed by an expert panel review (n = 13 and face validity was assessed by interviewing adolescents (n = 16. In the quantitative part of the study, in order to describe the psychometric properties of the scale, validity, reliability (internal consistency and test-retest and factor analysis were assessed.An item pool made up of 104 items was generated at the qualitative stage. After content validity was considered, this decreased to 47 items. In the quantitative stage, 582 adolescents aged 15-18 participated in the study with a mean age of 16.2 years. 51.2% of participants were females. In principal component factor analysis, 8 factors were loaded, which accounted for 53.37% of the variance observed. Reliability has been approved by α = 0.93 and the test-retest of the scale at two-week intervals indicated an appropriate stability for the scale (ICC = 0.93. The final questionnaire was approved with 44 items split into eight sections. The sections were titled: gain access to, reading, understanding, appraise, use, communication, self-efficacy and numeracy.The Health Literacy Measure for Adolescents (HELMA is a valid and reliable tool for the measurement of the health literacy of adolescents aged 15-18 and can be used to evaluate

  10. Sound Absorbers

    Science.gov (United States)

    Fuchs, H. V.; Möser, M.

    Sound absorption indicates the transformation of sound energy into heat. It is, for instance, employed to design the acoustics in rooms. The noise emitted by machinery and plants shall be reduced before arriving at a workplace; auditoria such as lecture rooms or concert halls require a certain reverberation time. Such design goals are realised by installing absorbing components at the walls with well-defined absorption characteristics, which are adjusted for corresponding demands. Sound absorbers also play an important role in acoustic capsules, ducts and screens to avoid sound immission from noise intensive environments into the neighbourhood.

    This study aims to assess the psychometric properties of the Chinese version of the WHOQOL-HIV BREF. Cross-sectional study. Centers for Disease Control and Prevention and infectious disease hospitals in three Chinese provinces. Sample of 1100 people living with HIV/AIDS (PLWHA). We recruited 1100 PLWHA to evaluate their quality of life (QOL) using the WHOQOL-HIV BREF. Of these participants, 57 were randomly selected to repeat the QOL evaluation 2 weeks later. The reliability of the WHOQOL-HIV BREF was assessed in terms of its internal consistency and test-retest reliability. The construct, concurrent, convergent, discriminant and known-group validity were also analysed. In addition, the factorial invariance across genders was assessed. Cronbach's α coefficient for the overall scale was 0.93. Except for the spirituality domain, which had an α below 0.70 (0.66), the other five domains showed adequate internal consistency. The test-retest reliability revealed a statistically significant intraclass correlation coefficient of 0.72-0.82 (p0.40 (r=0.40-0.67), except for the association between the spirituality domain and two general items (QOL: r=0.33; health status: r=0.36). Subjects with lower CD4 counts had lower scores for all domains (pgood psychometric characteristics among Chinese PLWHA. These findings offer promising support for the use of the WHOQOL-HIV BREF as a measure of QOL among Chinese PLWHA and in cross-cultural comparative studies on QOL. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    An alternative to bilateral cochlear implantation is offered by the Neurelec Digisonic(®) SP Binaural cochlear implant, which allows stimulation of both cochleae within a single device. The purpose of this prospective study was to compare a group of Neurelec Digisonic(®) SP Binaural implant users (denoted BINAURAL group, n = 7) with a group of bilateral adult cochlear implant users (denoted BILATERAL group, n = 6) in terms of speech perception, sound localization, and self-assessment of health status and hearing disability. Speech perception was assessed using word recognition at 60 dB SPL in quiet and in a 'cocktail party' noise delivered through five loudspeakers in the hemi-sound field facing the patient (signal-to-noise ratio = +10 dB). The sound localization task was to determine the source of a sound stimulus among five speakers positioned between -90° and +90° from midline. Change in health status was assessed using the Glasgow Benefit Inventory and hearing disability was evaluated with the Abbreviated Profile of Hearing Aid Benefit. Speech perception was not statistically different between the two groups, even though there was a trend in favor of the BINAURAL group (mean percent word recognition in the BINAURAL and BILATERAL groups: 70 vs. 56.7% in quiet, 55.7 vs. 43.3% in noise). There was also no significant difference with regard to performance in sound localization and self-assessment of health status and hearing disability. On the basis of the BINAURAL group's performance in hearing tasks involving the detection of interaural differences, implantation with the Neurelec Digisonic(®) SP Binaural implant may be considered to restore effective binaural hearing. Based on these first comparative results, this device seems to provide benefits similar to those of traditional bilateral cochlear implantation, with a new approach to stimulate both auditory nerves.

    Harlequin Ducks (Histrionicus histrionicus) were adversely affected by the Exxon Valdez oil spill (EVOS) in Prince William Sound (PWS), Alaska, and some have suggested effects continue two decades later. We present an ecological risk assessment evaluating quantitatively whether PWS seaducks continue to be at-risk from polycyclic aromatic hydrocarbons (PAHs) in residual Exxon Valdez oil. Potential pathways for PAH exposures are identified for initially oiled and never-oiled reference sites. Some potential pathways are implausible (e.g., a seaduck excavating subsurface oil residues), whereas other pathways warrant quantification. We used data on PAH concentrations in PWS prey species, sediments, and seawater collected during 2001–2008 to develop a stochastic individual-based model projecting assimilated doses to seaducks. We simulated exposures to 500,000 individuals in each of eight age/gender classes, capturing the variability within a population of seaducks living in PWS. Doses to the maximum-exposed individuals are ∼400–4,000 times lower than chronic toxicity reference values established using USEPA protocols for seaducks. These exposures are so low that no individual-level effects are plausible, even within a simulated population that is orders-of-magnitude larger than exists in PWS. We conclude that toxicological risks to PWS seaducks from residual Exxon Valdez oil two decades later are essentially non-existent. PMID:23723680

    postconstruction data are available. Data for the latter two sites thus reflect only the 2012 spring/summer seasons, which were further impacted by a direct hit by Hurricane Isaac in August 2012, which resulted in shoreward movement of approximately 14 percent of the bioengineered structures at Lake Fortuna. Given the shortened monitoring timeframe and significant differences in construction schedules, we were not able to provide a full postconstruction assessment of the sites or a full comparison of site success based on local site characteristics. Because many of the impacts that were identified for monitoring reflect long-term processes, results and data presented should be interpreted cautiously. Sustainable oyster reefs require recruitment, growth, and survival at a rate that keeps pace with mortality and shell disarticulation. Although one site failed to recruit (establishment plus survival > 50 millimeters [mm]) over two spawning seasons, two sites only had 6 months postconstruction data available for assessment. Although there are good data on the requirements for oyster growth, there is limited explicit information on the site-specific water quality, hydrodynamic, and biological interaction effects that may determine successful reef establishment. Furthermore, interannual variability can significantly affect reef establishment, and our shortened timeframe of sampling (less than one spawning season for two of the reefs; two spawning seasons for one reef), combined with a lack of prerestoration monitoring data, limit our ability to draw any conclusions about long-term reef sustainability. Bioengineered reefs are thought to provide some benefits to shoreline stabilization through their structure by immediately attenuating wave energies and directly reducing erosion rates at shorelines sheltered by the reefs but also by increasing sediment deposition behind the reefs. Preliminary data indicate differences in reef impact by site; given the short timeframe of postconstruction

    The global appraisal of individual needs (GAIN)-general individual severity scale (GAIN-GISS), and GAIN-short screener (GAIN-SS) are widely used diagnostic measures of internalizing disorders, externalizing disorders, substance abuse, and criminal and violent behavior. Although prevalent in clinical and research settings, there is only limited psychometric evidence of the dimensional structure of these scales. Our investigation used intake data from 6,909 adolescents presenting to outpatient substance abuse treatment facilities in the United States. Our analytic approach used exploratory and item factor analyses to evaluate the underlying factor structure. Multi- and unidimensional item response theory models were employed to evaluate the utility of the scales at providing precise score estimates at various locations of severity. Most scales were confirmed as unidimensional; scales with evidence of multidimensionality, identified as having a weak general dimension and strong specific dimensions using a bifactor IRT model, include the Crime and Violence Scale and the GAIN-SS.

    Auscultation of the lung is an inexpensive, noninvasive and easy-to-perform tool. It is an important part of the physical examination and is help ful to distinguish physiological respiratory sounds from pathophysiological events. Computerized lung sound analysis is a powerful tool for optimizing and quantifying electronic auscultation based on the specific lung sound spectral characteristics. The automatic analysis of respiratory sounds assumes that physiological and pathological sounds are reliably analyzed based on special algorithms. The development of automated long-term lungsound monitors enables objective assessment of different respiratory symptoms.

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. 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. 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. 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.

  20. Four Theorems on the Psychometric Function

    In a 2-alternative forced-choice (2AFC) discrimination task, observers choose which of two stimuli has the higher value. The psychometric function for this task gives the probability of a correct response for a given stimulus difference, . This paper proves four theorems about the psychometric function. Assuming the observer applies a transducer and adds noise, Theorem 1 derives a convenient general expression for the psychometric function. Discrimination data are often fitted with a Weibull function. Theorem 2 proves that the Weibull “slope” parameter, , can be approximated by , where is the of the Weibull function that fits best to the cumulative noise distribution, and depends on the transducer. We derive general expressions for and , from which we derive expressions for specific cases. One case that follows naturally from our general analysis is Pelli's finding that, when , . We also consider two limiting cases. Theorem 3 proves that, as sensitivity improves, 2AFC performance will usually approach that for a linear transducer, whatever the actual transducer; we show that this does not apply at signal levels where the transducer gradient is zero, which explains why it does not apply to contrast detection. Theorem 4 proves that, when the exponent of a power-function transducer approaches zero, 2AFC performance approaches that of a logarithmic transducer. We show that the power-function exponents of 0.4–0.5 fitted to suprathreshold contrast discrimination data are close enough to zero for the fitted psychometric function to be practically indistinguishable from that of a log transducer. Finally, Weibull reflects the shape of the noise distribution, and we used our results to assess the recent claim that internal noise has higher kurtosis than a Gaussian. Our analysis of for contrast discrimination suggests that, if internal noise is stimulus-independent, it has lower kurtosis than a Gaussian. PMID:24124456

Which self-report symptom scales or checklists are psychometrically sound for clinical use to assess sport-related concussion? Articles available in full text, published from the establishment of each database through December 2008, were identified from PubMed, Medline, CINAHL, Scopus, Web of Science, SPORTDiscus, PsycINFO, and AMED. Search terms included brain concussion, signs or symptoms, and athletic injuries, in combination with the AND Boolean operator, and were limited to studies published in English. The authors also hand searched the reference lists of retrieved articles. Additional searches of books, conference proceedings, theses, and Web sites of commercial scales were done to provide additional information about the psychometric properties and development for those scales when needed in articles meeting the inclusion criteria. Articles were included if they identified all the items on the scale and the article was either an original research report describing the use of scales in the evaluation of concussion symptoms or a review article that discussed the use or development of concussion symptom scales. Only articles published in English and available in full text were included. From each study, the following information was extracted by the primary author using a standardized protocol: study design, publication year, participant characteristics, reliability of the scale, and details of the scale or checklist, including name, number of items, time of measurement, format, mode of report, data analysis, scoring, and psychometric properties. A quality assessment of included studies was done using 16 items from the Downs and Black checklist1 and assessed reporting, internal validity, and external validity. The initial database search identified 421 articles. After 131 duplicate

    The Writing-To-Learn Attitude Survey (WTLAS) was developed to measure the effects of using writing-to-learn activities in the classroom, but adequate psychometric data have not been reported for the measure. Using the pretest scores from 149 basic and RN-to-BSN nursing students enrolled in a Nursing Management and Leadership course, the reliability and validity of the WTLAS were evaluated. The initial 30-item measure demonstrated acceptable reliability, but the item intercorrelations suggested revision of the subscales was appropriate. After exploratory factor analyses, the WTLAS was revised to 21 items and consists of two factors: Apprehensions about Writing Abilities and Perceived Benefits of Writing-To-Learn Activities. Both subscales possess acceptable internal consistency reliability and conceptually sound, significant correlations with a separate measure of writing apprehension. The revised WTLAS appears to have adequate psychometric properties for further use in the evaluation of students' perceptions of writing-to-learn activities.

    Nurses are committed to practice in an environmentally safe and healthy manner. However, nursing practice contributes significant negative impacts to the natural environment. We analyzed the psychometric properties of the Nurses Environmental Awareness Tool (NEAT), composed of 6 subscales, measuring awareness of environmental impacts and their health risks and ecological behaviors at work and home. The NEAT was given to 689 nurses via online survey software. Exploratory factor analyses and Cronbach's alpha were examined for each of the 6 subscales. The 6 subscales resulted in one-factor models with items demonstrating adequate reliability (α > .67). The NEAT is a psychometrically sound scale to measure nurses' awareness and behavior related to environmental impacts of nursing practice.

    The main contribution of this paper is the formulation of an alternative to experimental determination of loss factor and, consequently, to improve the predictions of airborne sound insulation for any type of monolithic or laminated glass. In addition, a review of the standards related to measurement of mechanical parameters of glass is carried out, with particular interest in laminated glass Indeed, one of the problems that arise in the current context of building acoustics is to meet the requirements of facades airborne sound insulation of existing Building Technical Code (BTC). It is known that the blind and the hollow part of the facade should be distinguished. The weakest part regarding to airborne sound insulation is the empty one (consisting of glass, woodwork and other elements). Choosing an adequate woodwork makes the glass surface become the limiting factor. The Constructive Elements Catalog (CEC) of the BTC, the UNE-EN 12758:2011 standard, as well as some, increasingly, data vendors provide information about airborne sound insulation for monolithic glass, laminated glass and double glazing. In the case of laminated glass, these data are limited only to those with a single intermediate layer, and also nonacoustic. Can therefore be said that there is a gap of knowledge in this regard. To obtain reliable predictions of airborne sound insulation of multilayer partitions, such as laminated glass, mechanical characteristics must be known, being loss factor one of the most important.

    Full Text Available The Center for Epidemiological Studies-Depression (CES-D scale is a widely used measure of depressive symptoms, but its psychometric properties have not been adequately evaluated among adults with HIV/AIDS. This study used an item response theory approach (Rasch analysis to evaluate the CES-D’s validity and reliability in relation to key demographic and clinical variables in adults with HIV/AIDS. A convenience sample of 347 adults with HIV/AIDS (231 males, 93 females, and 23 transgenders; age range 22–77 years completed the CES-D. A Rasch model application was used to analyze the CES-D’s rating scale functioning, internal scale validity, person-response validity, person-separation validity, internal consistency, differential item functioning (DIF, and differential test functioning. CES-D scores were generally high and associated with several demographic and clinical variables. The CES-D distinguished 3 distinct levels of depression and had acceptable internal consistency but lacked unidimensionality, five items demonstrated poor fit to the model, 15% of the respondents demonstrated poor fit, and eight items demonstrated DIF related to gender, race, or AIDS diagnosis. Removal of misfitting items resulted in minimal improvement in the CES-D’s substantive and structural validity. CES-D scores should be interpreted with caution in adults with HIV/AIDS, particularly when comparing scores across gender and racial groups.

    2014-11-01

    Health-related quality of life (HRQOL) has become an important patient reported outcome in health service research. The dermatology life quality index (DLQI) is the most commonly used instrument in dermatology. In recent years, the psychometric properties of the DLQI have been a subject of debate as requirements of modern test theory seem not to be fulfilled. The aim of this study was to test whether those violations also occur in patients with hand eczema. We collected data of 602 hand eczema patients who participated in an inpatient dermatology rehabilitation program in Germany. In order to report meaningful scores of the DLQI, data were analysed according to the principles of modern test theory. We calibrated the DLQI using the Rasch model, resulting in a 6 item version with a range between 0-15 points. This version showed no significant misfit to the Rasch model (p>0.14). By using a Rasch analysis the results were evaluated in a second sample of hand eczema patients (n=511). Even if all demographic characteristic of this sample were different, we were able to replicate the results found in this study (p>0.21). In conclusion, we recommend to use an alternative scoring procedure as presented in this article if the DLQI is used in hand eczema patients.

    The objective of this study was to test the psychometric properties of the QUALEFFO-41, an osteoporosis-specific health-related quality of life (HRQoL) measure, in a population sample. The study involved repeated administration of QUALEFFO-41 and another measure of HRQoL, the SF-36, to a stratified random population sample to test reliability and validity of instrument. The study was set in urban Harrow, Middlesex, UK and rural Cambridgeshire, UK. The participants were 83 males and 88 females aged 65-80+ years. Of the 230 individuals contacted 76.5% participated. The test-retest reliability of most QUALEFFO-41 items was good (Kappa 0.59-0.91) but two items had lower repeatability. Internal consistency was also generally good, but suggestive of some redundancy for three domains. The QUALEFFO-41 domains in general correlated well with SF-36 domains (r = 0.57 to r = 0.87), suggesting good validity. The QUALEFFO-41 has been shown to be a reliable and valid disease-specific HRQoL measure for osteoporosis. In population samples, it can be administered by post, or with a professional available to answer queries. Some specific items perform less well than may be desired and there is evidence of some redundancy, but further investigation is required and there are not yet grounds for textual change. We recommend continued use of this well-validated, reliable instrument.

    The aim of the current study was to examine the factor structure and the psychometric properties of the European Portuguese version of the World Health Organization's Quality of Life Instrument in HIV Infection (WHOQOL-HIV-Bref). Exploratory factor analysis (EFA) and confirmatory factors analysis (CFA) were conducted on self-reported WHOQOL-HIV-Bref data from 1196 HIV-positive patients, frequenting the main departments of infectious diseases in Portugal. An EFA with a randomly chosen subsample suggested a five-domain structure for the WHOQOL-HIV-Bref. CFA validated this five-domain structure in a separate subsample, but also revealed that the original six-domain model fit the data. Accordingly, it was decided to use the original factor structure. Based on the original six domain structure, the European Portuguese version of WHOQOL-HIV-Bref showed acceptable internal consistency (alpha range: 0.61-0.80 across domains). All domains (with exception of Spirituality) clearly discriminated subjects considering the CD4+ T cell count subgroups. These findings revealed additional insights about the factor structure of the WHOQOL-HIV-Bref and provided evidence in support of the original six-domain structure. This instrument showed to be a cross-culturally valid measure of quality of life, particularly useful when addressing the impact of HIV not only on physical and psychological well-being but also on several domains beyond health.

    Full Text Available Identification of possible cases suffering post-traumatic stress disorder (PTSD is important, especially in developing countries where traumatic events are typically prevalent. The Children’s Revised Impact of Events Scale is a reliable and valid measure that has two brief versions (13 items and 8 items to assess reactions to traumatic events among young people. The current study evaluated the psychometric properties of both versions of the CRIES in a sample of 1,342 children and adolescents aged 9–17 years (M = 12.3 years, SD = 2.12 recruited from six districts of Bangladesh. A sub-group of 120 children from four schools was re-tested on the measures within 3.5 weeks. Confirmatory factor analysis supported factor structures similar to those found in other studies for both versions of the CRIES. Multiple group confirmatory factor analysis showed gender and age-group differences within the sample, supporting established age and gender differences in prevalence of PTSD symptoms. Analyses also indicated moderate to excellent internal consistency and test-retest reliability and clear discriminant and convergent validity. These data support use of both the CRIES-13 and CRIES-8 to provide quick and psychometrically sound assessment of symptoms of PTSD among children and adolescents from Bangla-speaking communities.

    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.

    Progress in clinical research and in empirically supported interventions in the area of psychopathology in intellectual disabilities (ID) depends on high-quality assessment instruments. To this end, psychometric properties of four instruments were examined: the Aberrant Behavior Checklist (ABC), the Assessment of Dual Diagnosis (ADD), the Anxiety, Depression and Mood Scale (ADAMS), and the Social Performance Survey Schedule (SPSS). Data were collected in two community-based groups of adults with mild to profound ID (n = 263). Subscale reliability (internal consistency) ranged from fair to excellent for the ABC, the ADAMS, and the SPSS (mean coefficient α across ABC subscales was .87 (ranging from fair to excellent), the ADAMS subscales .83 (ranging from fair to good), and the SPSS subscales .91 (range from good to excellent). The ADD subscales had generally lower reliability scores with a mean of .59 (ranging from unacceptable to good). Convergent and discriminant validity was determined by bivariate Spearman ρ correlations between subscales of one instrument and the subscales of the other three instruments. For the most part, all four instruments showed solid convergent and discriminant validity. To examine the factorial validity, Confirmatory Factor Analyses (CFA) were attempted with the inter-item covariance matrix of each instrument. Generally, the data did not show good fits with the measurement models for the SPSS, ABC, or the ADAMS (CFA analyses with the ADD would not converge). However, most of the items on these three instruments had significant loadings on their respective factors.

    2006-02-01

    We demonstrate some procedures in the statistical computing environment R for obtaining maximum likelihood estimates of the parameters of a psychometric function by fitting a generalized nonlinear regression model to the data. A feature for fitting a linear model to the threshold (or other) parameters of several psychometric functions simultaneously provides a powerful tool for testing hypotheses about the data and, potentially, for reducing the number of parameters necessary to describe them. Finally, we illustrate procedures for treating one parameter as a random effect that would permit a simplified approach to modeling stimulus-independent variability due to factors such as lapses or interobserver differences. These tools will facilitate a more comprehensive and explicit approach to the modeling of psychometric data.

    2016-01-01

    In recent years, much effort has been invested in the development of new instruments for assessment of health-related quality of life (HRQOL). For many new instruments, modern psychometric methods, such as item response theory (IRT) models, have been used, either as supplemental to classical...... psychometric testing or as the primary methodological approach. We will use the term modern psychometric methods to refer to psychometric methods for multi-item scales that (1) examine the contribution of each item to the measurement properties of the overall scale and (2) recognize that items are categorical....... The models include Rasch models (Rasch 1980; Fischer and Molenaar 1995), other IRT models (Samejima 1969; van der Linden and Hambleton 1997), and factor analytic models for categorical data (Muthén 1984). “Modern” psychometric methods have actually a rather long history within psychiatric research (both...

    2012-01-01

    A significant minority of bereaved adults develops prolonged grief disorder (PGD), a syndrome encompassing debilitating symptoms of grief distinct from depression and anxiety. Few studies have examined the phenomenology and correlates of PGD among children and adolescents. In part, this is due to the lack of a psychometrically sound questionnaire to assess PGD symptoms in these groups. Based on an adult measure of PGD, we developed two questionnaires of PGD symptoms for children and adolescents named the Inventory of Prolonged Grief for Children (IPG-C) and Inventory of Prolonged Grief for Adolescents (IPG-A), respectively. Psychometric properties of these measures were examined in three samples, including mostly parentally bereaved children (aged 8-12 years, total sample n = 169) and adolescents (aged 13-18 years, total sample n = 153). First, findings showed that items of the IPG-C and IPG-A represented one underlying dimension. Second, the internal consistency and temporal stability of both questionnaires were adequate. Third, findings supported the concurrent validity (e.g., significant correlations with measures of depression and post-traumatic stress-disorder [PTSD]), convergent and divergent validity (stronger correlations with similar questionnaires of 'traumatic grief' than with two dissimilar questionnaires of 'ongoing presence' and 'positive memories') and incremental validity (significant correlations with an index of functional impairment, even when controlling for concomitant depression and PTSD) of the IPG-C and IPG-A. This report provides further evidence of the clinical significance of PGD symptoms among children and adolescents and promising psychometric properties of questionnaires that can be used to assess these symptoms. The Inventory of Prolonged Grief for Children (IPG-C) and Inventory of Prolonged Grief for Adolescents (IPG-A) were developed to be able to assess symptoms of Prolonged Grief Disorder (PGD) among children and adolescents.

    Full Text Available Abstract Background The Osteoporosis Patient Satisfaction Questionnaire (OPSAT-Q is a new measure of patient satisfaction with bisphosphonate treatment for osteoporosis. The objective of this study was to evaluate the psychometric characteristics of the OPSAT-Q. Methods The OPSAT-Q contains 16 items in four subscales: Convenience, Confidence with Daily Activities, Side Effects, and Overall Satisfaction. All four subscale scores and an overall composite satisfaction score (CSS can be computed. The OPSAT-Q, Osteoporosis Targeted Quality of Life (OPTQoL, and sociodemographic/clinical questionnaires, including 3 global items on convenience, functioning and side effects, were self-administered to women with osteoporosis or osteopenia recruited from four US clinics. Analyses included item and scale performance, internal consistency reliability, reproducibility, and construct validity. Reproducibility was measured using the intraclass correlation coefficient (ICC via a follow-up questionnaire completed by participants 2 weeks post baseline. Results 104 women with a mean age of 65.1 years participated. The majority were Caucasian (64.4%, living with someone (74%, and not currently employed (58.7%. 73% had osteoporosis and 27% had osteopenia. 80% were taking weekly bisphosphonates and 18% were taking daily medication (2% missing data. On a scale of 0–100, individual patient subscale scores ranged from 17 to 100 and CSS scores ranged from 44 to 100. All scores showed acceptable internal consistency reliability (Cronbach's alpha > 0.70 (range 0.72 to 0.89. Reproducibility ranged from 0.62 (Daily Activities to 0.79 (Side Effects for the subscales; reproducibility for the CSS was 0.81.

    Respiratory sounds (RS) are produced by turbulent airflows through the airways and are inhomogeneously transmitted through different media to the chest surface, where they can be recorded in a non-invasive way. Due to their mechanical nature and airflow dependence, RS are affected by respiratory diseases that alter the mechanical properties of the respiratory system. Therefore, RS provide useful clinical information about the respiratory system structure and functioning. Recent...

    Full Text Available Este trabajo presenta el diseño de un instrumento autoadministrable destinado a evaluar qué atributos se adjudican más frecuentemente a las personas sabias. El concepto sabiduría forma parte de los constructos investigados por la Psicología Positiva, que estudia los recursos salugénicos y las fortalezas presentes en los individuos. Supone una competencia general caracterizada como una experiencia de vida basada en el conocimiento pragmático que requiere de habilidades meta/ analíticas, reflexivas y evaluativas. Se describe como una forma especial de procesamiento cognitivo que se distingue de la creatividad y de la inteligencia, aunque al analizarla no sólo se toman en cuenta los procesos cognitivos implicados sino también atributos como la empatía, la inteligencia, y la capacidad analítica y reflexiva. Enmarcado en estas consideraciones, el objetivo de este trabajo consistía en diseñar y analizar psicométricamente el instrumento, a partir de las respuestas brindadas por 1100 adultos de 30 a 59 años ( edad= 44.89; DT= 7.74; 55% varones, 45% mujeres, residentes en Buenos Aires (Ciudad, Conurbano y Provincia.

    2015-12-01

    The burnout syndrome contributes to the deterioration in the quality of personal life as well as lower quality practice in healthcare personnel. Researchers have been concerned about the psychometric limitations of some previous questionnaires designed to evaluate burnout. The Spanish Burnout Inventory was developed to address the problems associated with other instruments, but it has not yet been validated in staff nurses. This study provides evidence that the Spanish Burnout Inventory has adequate psychometric properties to estimate burnout in staff nurses. The Spanish Burnout Inventory offers a theoretical proposal to explain the different components of burnout. The Spanish Burnout Inventory provides researchers and practitioners with an expanded conceptualization of the burnout syndrome, which can facilitate the diagnosis and treatment of nursing professionals. Researchers have been concerned about the psychometric limitations of the some previous questionnaires designed to evaluate burnout. To address these problems associated with previous instruments, the Spanish Burnout Inventory (SBI) was developed. The instrument has not yet been validated in staff nurses. The purpose of this paper was to evaluate the psychometric properties of the SBI. The sample consisted of 720 staff nurses from two Spanish general hospitals. The instrument is composed of 20 items distributed in four dimensions: Enthusiasm towards the job (five items), Psychological exhaustion (four items), Indolence (six items) and Guilt (five items). Data were subjected to confirmatory factor analysis. To assess the factorial validity of the SBI, four alternative models were tested. Results show that the four-factor model of the SBI has adequate psychometric properties for the study of burnout in staff nurses. This model fitted the data better than the alternative models. The study provides evidence of the adequate psychometric properties of a measure to evaluate burnout in nursing professionals. The

  3. Four theorems on the psychometric function.

    Directory of Open Access Journals (Sweden)

    Keith A May

    Full Text Available In a 2-alternative forced-choice (2AFC discrimination task, observers choose which of two stimuli has the higher value. The psychometric function for this task gives the probability of a correct response for a given stimulus difference, Δx. This paper proves four theorems about the psychometric function. Assuming the observer applies a transducer and adds noise, Theorem 1 derives a convenient general expression for the psychometric function. Discrimination data are often fitted with a Weibull function. Theorem 2 proves that the Weibull "slope" parameter, β, can be approximated by β(Noise x β(Transducer, where β(Noise is the β of the Weibull function that fits best to the cumulative noise distribution, and β(Transducer depends on the transducer. We derive general expressions for β(Noise and β(Transducer, from which we derive expressions for specific cases. One case that follows naturally from our general analysis is Pelli's finding that, when d' ∝ (Δx(b, β ≈ β(Noise x b. We also consider two limiting cases. Theorem 3 proves that, as sensitivity improves, 2AFC performance will usually approach that for a linear transducer, whatever the actual transducer; we show that this does not apply at signal levels where the transducer gradient is zero, which explains why it does not apply to contrast detection. Theorem 4 proves that, when the exponent of a power-function transducer approaches zero, 2AFC performance approaches that of a logarithmic transducer. We show that the power-function exponents of 0.4-0.5 fitted to suprathreshold contrast discrimination data are close enough to zero for the fitted psychometric function to be practically indistinguishable from that of a log transducer. Finally, Weibull β reflects the shape of the noise distribution, and we used our results to assess the recent claim that internal noise has higher kurtosis than a Gaussian. Our analysis of β for contrast discrimination suggests that, if internal noise is

    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. 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 100-mm visual analog scales. 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 provided preliminary psychometric support for items assessing each DEQ construct (feel, high, dislike, like, and more). 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.

    Quantifying the basal roughness of ice sheets is important for understanding and constraining the role of basal traction on ice dynamics. Numerical model simulations demonstrate high sensitivity to the parametrisation of the lower boundary condition, which is governed by both basal roughness and the thermal state of the bed. In terms of ice dynamics history, basal roughness can reveal aspects of past behaviour as well as provide insight towards more recent flow distribution of marine sediments. Basal roughness information, defined here in general terms as the irregularity of the basal interface relative to a reference surface, can be obtained from radar-sounding data in two physically different ways. Firstly, via the statistical properties of along-track topography (e.g. from spectral analysis); and secondly via the electromagnetic scattering properties of the radar pulse (e.g. by quantifying the spread of the distribution of scattered energy). In general, the basal roughness of the Greenland Ice Sheet has been little studied, and the vast increase in recent Operation Ice Bridge radar-sounding data presents an opportunity for comprehensive, quantitative ice-sheet-wide analysis. Here we present a synthesis of basal scattering and topographic based roughness information for the Greenland Ice Sheet, along with a comparison to present day numerical model output including ice velocity, basal traction, and basal temperature. One central topic which we address is the scale dependence of basal roughness information that is inferred from both analysis methods, and the relationship with basal sliding physics. Consideration of scale is important since basal sliding is primarily controlled by higher frequency roughness. The other topic that we consider is identifying whether there are any defined and unambiguous roughness characteristics in regions where there is suspected to be a thawed basal interface. An overall goal of this work is to integrate basal roughness information

    Full Text Available Brett Williams,1 Adiva Sifris,2 Marty Lynch1 1Department of Community Emergency Health and Paramedic Practice, Faculty of Medicine, Nursing and Health Sciences, 2Faculty of Law, Monash University, Frankston, VIC, Australia Background: A growing body of literature indicates that empathic behaviors are positively linked, in several ways, with the professional performance and mental well-being of lawyers and law students. It is therefore important to assess empathy levels among law students using psychometrically sound tools that are suitable for this cohort.Participants and methods: The 20-item Jefferson Scale of Empathy – Health Profession Students Version was adapted for a law context (eg, the word “health care” became “legal”, and the new Jefferson Scale of Empathy – Law Students (JSE-L-S version was completed by 275 students at Monash University, Melbourne, Australia. Data were subjected to principal component analysis.Results: Four factors emerged from the principal component analysis (“understanding the client’s perspective”, “responding to clients’ experiences and emotions”, “responding to clients’ cues and behaviors”, and “standing in clients’ shoes”, which accounted for 46.7% of the total variance. The reliability of the factors varied, but the overall 18-item JSE-L-S yielded a Cronbach’s alpha coefficient of 0.80. Several patterns among the item loadings were similar to those reported in studies using other versions of the Jefferson Scale of Empathy.Conclusion: The JSE-L-S appears to be a reliable measure of empathy among undergraduate law students, which could help provide insights into law student welfare and future performance as legal practitioners. Additional evaluation of the JSE-L-S is required to disambiguate some of the minor findings explored. Adjustments may improve the psychometric properties.

    Konrad, Christopher P.

    2015-01-01

    Ecological functions and flood-related risks were assessed for floodplains along the 17 major rivers flowing into Puget Sound Basin, Washington. The assessment addresses five ecological functions, five components of flood-related risks at two spatial resolutions—fine and coarse. The fine-resolution assessment compiled spatial attributes of floodplains from existing, publically available sources and integrated the attributes into 10-meter rasters for each function, hazard, or exposure. The raster values generally represent different types of floodplains with regard to each function, hazard, or exposure rather than the degree of function, hazard, or exposure. The coarse-resolution assessment tabulates attributes from the fine-resolution assessment for larger floodplain units, which are floodplains associated with 0.1 to 21-kilometer long segments of major rivers. The coarse-resolution assessment also derives indices that can be used to compare function or risk among different floodplain units and to develop normative (based on observed distributions) standards. The products of the assessment are available online as geospatial datasets (Konrad, 2015; http://dx.doi.org/10.5066/F7DR2SJC).

    Vehicle sounds play an important role concerning customer satisfaction and can show another differentiating factor of brands. With an online survey of 1762 German and American customers, the requirement characteristics of high-quality vehicle sounds were determined. On the basis of these characteristics, a requirement profile was generated for every analyzed sound. These profiles were investigated in a second study with 78 customers using real vehicles. The assessment results of the vehicle sounds can be represented using the dimensions "timbre", "loudness", and "roughness/sharpness". The comparison of the requirement profiles and the assessment results show that the sounds which are perceived as pleasant and high-quality, more often correspond to the requirement profile. High-quality sounds are characterized by the fact that they are rather gentle, soft and reserved, rich, a bit dark and not too rough. For those sounds which are assessed worse by the customers, recommendations for improvements can be derived. Copyright © 2017 Elsevier Ltd. All rights reserved.

  15. Assessing student understanding of sound waves and trigonometric reasoning in a technology-rich, project-enhanced environment

    Wilhelm, Jennifer Anne

    This case study examined what student content understanding could occur in an inner city Industrial Electronics classroom located at Tree High School where project-based instruction, enhanced with technology, was implemented for the first time. Students participated in a project implementation unit involving sound waves and trigonometric reasoning. The unit was designed to foster common content learning (via benchmark lessons) by all students in the class, and to help students gain a deeper conceptual understanding of a sub-set of the larger content unit (via group project research). The objective goal of the implementation design unit was to have students gain conceptual understanding of sound waves, such as what actually waves in a wave, how waves interfere with one another, and what affects the speed of a wave. This design unit also intended for students to develop trigonometric reasoning associated with sinusoidal curves and superposition of sinusoidal waves. Project criteria within this design included implementation features, such as the need for the student to have a driving research question and focus, the need for benchmark lessons to help foster and scaffold content knowledge and understanding, and the need for project milestones to complete throughout the implementation unit to allow students the time for feedback and revision. The Industrial Electronics class at Tree High School consisted of nine students who met daily during double class periods giving 100 minutes of class time per day. The class teacher had been teaching for 18 years (mathematics, physics, and computer science). He had a background in engineering and experience teaching at the college level. Benchmark activities during implementation were used to scaffold fundamental ideas and terminology needed to investigate characteristics of sound and waves. Students participating in benchmark activities analyzed motion and musical waveforms using probeware, and explored wave phenomena using waves

  16. A psychometric evaluation of the digital logic concept inventory

    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.

    Fear of suffocation and fear of restriction are thought to underlie claustrophobia and can be assessed with the Claustrophobia Questionnaire (CLQ; Radomsky et al., 2001). A first study tested the psychometric properties of a Dutch version of the CLQ. Students (N=363) completed a Dutch translation of the CLQ and a set of other questionnaires assessing other specific fears, anxiety or depression. Results confirmed the two-factor structure and showed that the Dutch version of the CLQ has good psychometric properties. A second study tested the predictive validity of the Dutch CLQ. Participants (N=23) were exposed each to nine claustrophobic situations with elements of suffocation, restriction or both. The Dutch CLQ was found to be a significant predictor of fear and respiratory reactivity during claustrophobic exposure. It can be concluded that the Dutch version of the CLQ is a reliable and valid instrument to assess claustrophobic fear. Copyright 2010 Elsevier Ltd. All rights reserved.

    2014-03-01

    Full Text Available Research suggests that intolerance of uncertainty may be important in understanding worry and may play a key role in the etiology and maintenance of worry. Intolerance of uncertainty is measured using the Intolerance of Uncertainty Scale (IUS, which has been shown to be reliable and valid in many studies. The aim of the present study was to develop a Lithuanian version of this instrument. 228 university students completed the scale. The Lithuanian version of the IUS was found to have good psychometric properties. The IUS showed high internal consistency and good test-retest reliability over a five-week period, and good convergent and divergent validity when assessed with measures of trait anxiety, situational anxiety, and depression. Factor analysis indicated that the IUS has a two-factor structure that represents the beliefs that “uncertainty about the future is unfair” and that “uncertainty has negative behavioral and self-referent implications”. In conclusion, it was found that the Lithuanian version of the IUS is a sound scale for assessing intolerance of uncertainty.

    2017-05-01

    Full Text Available Objectives: Acoustic stimulation or sound therapy is proposed as a main treatment option for chronic subjective tinnitus. To further probe the field of acoustic stimulations for tinnitus therapy, this exploratory study compared 10 Hz amplitude modulated (AM sounds (two pure tones, noise, music, and frequency modulated (FM sounds and unmodulated sounds (pure tone, noise regarding their temporary suppression of tinnitus loudness. First, it was hypothesized that modulated sounds elicit larger temporary loudness suppression (residual inhibition than unmodulated sounds. Second, with manipulation of stimulus loudness and duration of the modulated sounds weaker or stronger effects of loudness suppression were expected, respectively.Methods: We recruited 29 participants with chronic tonal tinnitus from the multidisciplinary Tinnitus Clinic of the University of Regensburg. Participants underwent audiometric, psychometric and tinnitus pitch matching assessments followed by an acoustic stimulation experiment with a tinnitus loudness growth paradigm. In a first block participants were stimulated with all of the sounds for 3 min each and rated their subjective tinnitus loudness to the pre-stimulus loudness every 30 s after stimulus offset. The same procedure was deployed in the second block with the pure tone AM stimuli matched to the tinnitus frequency, manipulated in length (6 min, and loudness (reduced by 30 dB and linear fade out. Repeated measures mixed model analyses of variance (ANOVA were calculated to assess differences in loudness growth between the stimuli for each block separately.Results: First, we found that all sounds elicit a short-term suppression of tinnitus loudness (seconds to minutes with strongest suppression right after stimulus offset [F(6, 1331 = 3.74, p < 0.01]. Second, similar to previous findings we found that AM sounds near the tinnitus frequency produce significantly stronger tinnitus loudness suppression than noise [vs. Pink

    To assess the validity of the Finnish translation of the 12-item World Health Organization Disability Assessment Schedule (WHODAS 2.0). Cross-sectional cohort survey study. Physical and Rehabilitation Medicine outpatient university clinic. The 501 consecutive patients with chronic musculoskeletal pain. Exploratory factor analysis and a graded response model using item response theory analysis were used to assess the constructs and discrimination ability of WHODAS 2.0. The exploratory factor analysis revealed two retained factors with eigenvalues 5.15 and 1.04. Discrimination ability of all items was high or perfect, varying from 1.2 to 2.5. The difficulty levels of seven out of 12 items were shifted towards the elevated disability level. As a result, the entire test characteristic curve showed a shift towards higher levels of disability, placing it at the point of disability level of +1 (where 0 indicates the average level of disability within the sample). The present data indicate that the Finnish translation of the 12-item WHODAS 2.0 is a valid instrument for measuring restrictions of activity and participation among patients with chronic musculoskeletal pain.

    Dahlheim, M.E.; Von Ziegesar, O.

    1993-12-01

    Photo-identification studies of Prince William Sound humpback whales were conducted from May to September in 1989 and 1990 to assess the impact on the spill on humpback whale life history and ecology. In 1989, concurrent studies were conducted in Southeast Alaska on humpback whales to determine if whales avoided contaminated waters of Prince William Sound and moved to other northern feeding areas. In 1989, photographic analysis of Prince William Sound humpbacks resulted in the identification of 59 whales. In 1990, 66 whales were documented. The increase in whale sightings may have been due to the increase in effort during the 1989 and 1990 season. Because of the difference in survey effort before and after the spill, it is impossible to determine if there was a difference in the number of humpback whales using the Sound. Distribution varied among years and may be related to prey distribution.

    This study describes the psychometric properties of the Children's Separation Anxiety Scale (CSAS), which assesses separation anxiety symptoms in childhood. Participants in Study 1 were 1,908 schoolchildren aged between 8 and 11. Exploratory factor analysis identified four factors: worry about separation, distress from separation, opposition to separation, and calm at separation, which explained 46.91% of the variance. In Study 2, 6,016 children aged 8-11 participated. The factor model in Study 1 was validated by confirmatory factor analysis. The internal consistency (α = 0.82) and temporal stability (r = 0.83) of the instrument were good. The convergent and discriminant validity were evaluated by means of correlations with other measures of separation anxiety, childhood anxiety, depression and anger. Sensitivity of the scale was 85% and its specificity, 95%. The results support the reliability and validity of the CSAS.

    Tinnitus is a very complex phenomenon with various mechanisms of origin. Multimodal and interdisciplinary treatment is the most effective form of treatment for patients with chronic tinnitus. In order to assess existing comorbidity in tinnitus patients as well as to treat the patients individually, a comprehensive and differentiated diagnosis is needed. Since standardized guidelines for the use of relevant instruments in the diagnosis of tinnitus have been lacking hitherto, we present here psychometric questionnaires which have already been used effectively in the research, diagnosis and therapy of tinnitus in the present article. The questionnaires measure the severity of tinnitus, depression and anxiety, the perceived stress, personal resources as well as the quality of life of patients.

Such evaluations provide physicians with non-biased valuations of both their strengths and their weaknesses, offering an opportunity for improvement in their work. Studies have shown that MSF is particularly effective for emergency care physicians. The study was undertaken in a military teaching hospital in Bahrain. A total of 30 emergency physicians (the total number of emergency physicians in our hospital), 16 males and 14 females, were evaluated using multisource feedback. Each emergency physician was assessed by three groups of raters, including 4 emergency physicians, 4 referral physicians from other departments, and 4 coworkers from within the emergency department. Feasibility of the questionnaire was analyzed via response rates, average time required to complete it, and the number of raters required to produce reliable results. We used exploratory factor analysis to examine for the construct validity. Cronbach's coefficient was calculated to measure the internal consistency reliability of the instrument. The total mean response rate was 74.2 %, and the self-reported average time needed to fill out each survey was 4.3 min, indicating a good feasibility of the questionnaire. Reliability analysis indicated that the full-scale instrument had high internal consistency (Cronbach's α 0.98). Factor analysis showed that the data on the questionnaire decomposed into three factors, which accounted for 72.6 % of the total variance: professionalism, collaboration, and communication. The generalizability coefficients (Ep(2)) were 0.76 for the surveys. Out of the 30 candidates, 26 participated in the knowledge test. The total mean score of the knowledge exam was 34.52, with scores ranging from 17 to 54. Based on this study's results, we conclude that the instruments and procedures used have high reliability, validity, and

    We created the Daily Sessions, Frequency, Age of Onset, and Quantity of Cannabis Use Inventory (DFAQ-CU) because the current lack of psychometrically sound inventories for measuring these dimensions of cannabis use has impeded research on the effects of cannabis in humans. A sample of 2,062 cannabis users completed the DFAQ-CU and was used to assess the DFAQ-CU's factor structure and reliability. To assess validity, a subsample of 645 participants completed additional measures of cannabis dependence and problems (Marijuana Smoking History Questionnaire [MSHQ], Timeline Followback [TLFB], Cannabis Abuse Screening Test [CAST], Cannabis Use Disorders Identification Test Revised [CUDIT-R], Cannabis Use Problems Identification Test [CUPIT], and Alcohol Use Disorder Identification Test [AUDIT]). A six-factor structure was revealed, with factors measuring: daily sessions, frequency, age of onset, marijuana quantity, cannabis concentrate quantity, and edibles quantity. The factors were reliable, with Cronbach's alpha coefficients ranging from .69 (daily sessions) to .95 (frequency). Results further provided evidence for the factors' convergent (MSHQ, TLFB), predictive (CAST, CUDIT-R, CUPIT), and discriminant validity (AUDIT). The DFAQ-CU is the first psychometrically sound inventory for measuring frequency, age of onset, and quantity of cannabis use. It contains pictures of marijuana to facilitate the measurement of quantity of marijuana used, as well as questions to assess the use of different forms of cannabis (e.g., concentrates, edibles), methods of administering cannabis (e.g., joints, hand pipes, vaporizers), and typical THC levels. As such, the DFAQ-CU should help facilitate research on frequency, quantity, and age of onset of cannabis use.

  1. Acoustic assessment of sound scattering zooplankton in warm- and cold-core eddies in the Gulf of Mexico

    Zimmerman, Robert Allen

    Zooplankton and micronekton which cause a density discontinuity with the surrounding seawater reflect acoustic energy. This acoustic backscatter intensity (ABI) was measured using a vessel mounted 153 kHz acoustic Doppler current profiler. The ABI was used to describe vertical migration and distribution of sound scatterers in several mesoscale hydrographic features commonly found in the Gulf of Mexico: cold-core rings (CCRs), warm-core Loop Current eddies (LCEs) and the Loop Current (LC). The present paradigm contends that cold- core (cyclonic) features are mesoscale areas of enhanced production due to an influx of new nitrogen to surface waters as a result of divergent flow. The null hypothesis which was tested in this study was that the acoustic signatures of these features were not significantly different from one another. Clear diel differences in all of the features and a robust, positive correlation between ABI and plankton and micronekton wet displacement volume collected in MOCNESS tows in the upper 100 m of the water column were observed. During the day, ABI in CCRs was significantly greater than in LCEs and in the LC with regards to the upper 200 m. However, ABI in the LCEs and LC were not significantly different from each other. During the night, the ABI in the upper 50 m of the CCRs was significantly greater than that in the LCEs and the LC. However, there were no differences between features when ABI at night was summed for the entire upper 200 m, due to substantial vertical migrations of organisms into the upper 200 m of the water column at night. Two LCEs were revisited at an age of 8-9 months after their initial acoustic transects. The null hypothesis that there would be no significant difference in integrated ABI when the LCEs were resampled was rejected: both LCEs showed a reduction in integrated ABI over the upper 200 m. Further investigations into the faunal changes of these features are warranted, but the ADCP should continue to be a useful

    In the pasture-based, seasonally calving dairy herds of southern Australia, the mating period usually consists of an initial artificial insemination period followed by a period of natural service using herd bulls. Bull breeding soundness evaluations (BBSE) were performed on 256 bulls from 32 dairy herds in southwest Victoria, using guidelines produced by the Australian Cattle Veterinarians, before and immediately after a single natural mating period. At the same time, herd managers were questioned regarding the management of the bulls. The objectives of this study were to describe the management practices of dairy herd bulls; to describe the causes of increased risk of reduced fertility in dairy herd bulls, as measured by a standard BBSE; and to describe the reasons for bull removal by herd managers during mating. At the premating BBSE, 19.5% of bulls were classified as high risk of reduced fertility, mostly due to physical abnormalities and reduced semen quality. At the postmating BBSE, 36.5% of bulls were classified as high risk of reduced fertility, mostly due to physical abnormalities, primarily lameness. Of the bulls used, 15.9% were removed from normal mating use by the herd manager, predominantly due to lameness and injuries. A premating BBSE is recommended in dairy herd bulls to identify bulls at risk of reduced fertility. Lameness is the most common problem in dairy herd bulls during the natural mating period, and risk factors associated with lameness in these bulls should be identified to better manage herd bulls.

Further, the cognitive complexity surrounding test performance means that the response-time based measures and the lie detector tests for revealing concealed life-events (e.g., doping use) are prone to produce false or non-interpretable outcomes in field...... settings. Differences in social-cognitive characteristics of doping behaviour that are tested at group level (doping users vs. non-users) cannot be extrapolated to individuals; nor these psychometric measures used for individual diagnostics. In this paper, we present a position statement calling for policy...... guidance on appropriate use of psychometric assessments in the pursuit of clean sport.

    Muscle samples were collected from pup, juvenile and adult Weddell seals (Leptonychotes weddellii) near McMurdo Sound, Antarctica during the austral summer of 2006. Blubber samples were collected from juvenile and adult seals. Samples were analyzed for emerging and legacy persistent organic pollutants (POPs) including current and historic-use organochlorine pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Of the 41 target analytes, 28 contaminants were recovered from the Weddell seal blubber, in this order of prevalence: p,p'-DDE, p,p'-DDT, trans-nonachlor, mirex, cis-nonachlor, PCB 153, PCB 138, dieldrin, heptachlor epoxide, nonachlor III, PCB 187, oxychlordane, cis-chlordane, PCB 118, PBDE 47, PCB 156, PCB 149, PCB 180, PCB 101, PCB 170, PCB 105, o,p'-DDT, PCB 99, trans-chlordane, PCB 157, PCB 167, PCB 189, and PCB 114. Fewer POPs were found in the muscle samples, but were similar in the order of prevalence to that of the blubber: p,p'-DDE, o,p'-DDT, trans-nonachlor, nonachlor III, oxychlordane, p,p'-DDT, dieldrin, mirex, cis-nonachlor, PCB 138, and PCB 105. Besides differences in toxicant concentrations reported between the muscle and blubber, we found differences in POP levels according to age class and suggest that differences in blubber storage and/or mobilization of lipids result in age class differences in POPs. To our knowledge, such ontogenetic associations are novel. Importantly, data from this study suggest that p,p'-DDT is becoming less prevalent temporally, resulting in an increased proportion of its metabolite p,p'-DDE in the tissues of this top predator. In addition, this study is among the first to identify a PBDE congener in Weddell seals near the McMurdo Station. This may provide evidence of increased PBDE transport and encroachment in Antarctic wildlife.

    The Sexual Relationship Power Scale (SRPS) was developed over a decade ago to address the lack of reliable and valid measures of relationship power in social, behavioral and medical research. The SRPS and its two subscales (relationship control [RC], decision-making dominance [DMD]) have been used extensively in the field of HIV prevention and sexual risk behavior. We performed a systematic review of the psychometric properties of the SRPS and subscales as reported in the HIV/AIDS literature from 2000 to 2012. A total of 54 published articles were identified, which reported reliability or construct validity estimates of the scales. Description of the psychometric properties of the SRPS and subscales is reported according to study population, and several cross-population trends were identified. In general, the SRPS and RC subscale exhibited sound psychometric properties across multiple study populations and research settings. By contrast, the DMD subscale had relatively weak psychometric properties, especially when used with specific populations and research settings. Factors that influenced the psychometric properties of the various scales and subscales included the study population, mean age of the sample, number of items retained in the scale, and modifications to the original scales. We conclude with recommendations for (1) the application and use of the SRPS and subscales, (2) reporting of psychometric properties of the scales in the literature, and (3) areas for future research.

    The Activity Card Sort is a valid and reliable assessment tool that was created to assess Participation. It has been translated to several languages and adapted to different international cultures. The most recent version of this tool is the Arabic Heritage Activity Card Sort (A-ACS). The purpose of this study was to establish the psychometric properties of the new Arabic version in Jordanian adults. Forty three Jordanian patients with multiple sclerosis (MS) and 62 healthy adults were recruited to test the psychometric properties of the tool. The A-ACS correlated moderately with the participation index of the Mayo-Portland Adaptability Inventory (r = -0.458, p Heritage of the Activity Card Sort is a valid and reliable tool for Arabic-speaking occupational therapists to use when assessing participation in Jordanian patients with MS or healthy adults. Limitations of this study include using only one diagnostic group from Jordan and examining only the Recovery and Community Versions of the tool. Future studies are needed to examine further psychometric properties for patients with different diagnoses and from different countries in the Arabic region for all three versions of the A-ACS.

    Online questionnaires for measuring common mental health disorders such as depression and anxiety disorders are increasingly used. The psychometrics of several pen-and-paper questionnaires have been re-examined for online use and new online instruments have been developed and tested for validity as well. This study aims to review and synthesise the literature on this subject and provide a framework for future research. We searched Medline and PsycINFO for psychometric studies on online instruments for common mental health disorders and extracted the psychometric data. Studies were coded and assessed for quality by independent raters. We included 56 studies on 62 online instruments. For common instruments such as the CES-D, MADRS-S and HADS there is mounting evidence for adequate psychometric properties. Further results are scattered over different instruments and different psychometric characteristics. Few studies included patient populations. We found at least one online measure for each of the included mental health disorders and symptoms. A small number of online questionnaires have been studied thoroughly. This study provides an overview of online instruments to refer to when choosing an instrument for assessing common mental health disorders online, and can structure future psychometric research.

    Suboptimal care for people with dementia in hospital settings has been reported and is attributed to the lack of knowledge and inadequate attitudes in dementia care among health professionals. Educational interventions have been widely used to improve care outcomes; however, Chinese-language instruments used in dementia educational interventions for health professionals are lacking. The aims of this study were to select, translate and evaluate instruments used in dementia educational interventions for Chinese health professionals in acute-care hospitals. A cross-sectional study design was used. A modified stratified random sampling was used to recruit 442 participants from different levels of hospitals in Changsha, China. Dementia care competence was used as a framework for the selection and evaluation of Alzheimer's Disease Knowledge Scale and Dementia Care Attitudes Scale for health professionals in the study. These two scales were translated into Chinese using forward and back translation method. Content validity, test-retest reliability and internal consistency were assessed. Construct validity was tested using exploratory factor analysis. Known-group validity was established by comparing scores of Alzheimer's Disease Knowledge Scale and Dementia Care Attitudes Scale in two sub-groups. A person-centred care scale was utilised as a gold standard to establish concurrent validity of these two scales. Results demonstrated acceptable content validity, internal consistency, test-retest reliability and concurrent validity. Exploratory factor analysis presented a single-factor structure of the Chinese Alzheimer's Disease Knowledge Scale and a two-factor structure of the Chinese Dementia Care Attitudes Scale, supporting the conceptual dimensions of the original scales. The Chinese Alzheimer's Disease Knowledge Scale and Chinese Dementia Care Attitudes Scale demonstrated known-group validity evidenced by significantly higher scores identified from the sub-group with a

However there is scant comprehensive information readily available to assist clinicians to choose appropriate assessment instruments with sound psychometric and clinical properties.Objective: A national insurer commissioned the development of a compendium of assessment instruments to identify adults with, or at-risk of developing, persistent pain. This paper reports on the instrument identification and review process.Methods: A comprehensive systematic literature review was undertaken of assessment instruments for persistent pain of noncancer origin, and their developmental literature. Only assessment instruments which were developed for patients with pain, or tested on them, were included. A purpose-built ‘Ready Reckoner’ scored psychometric properties and clinical utility.Results: One hundred sixteen potentially useful instruments were identified, measuring severity, psychological, functional and/or quality of life constructs of persistent pain. Forty-five instruments were short-listed, with convincing psychometric properties and clinical utility. There were no standard tests for psychometric properties, and considerable overlap of instrument purpose, item construct, wording, and scoring.Conclusion: No one assessment instrument captured all the constructs of persistent pain. While the compendium focuses clinicians’ choices, multiple instruments are required for comprehensive assessment of adults with persistent pain.Keywords: persistent pain, assessment, psychometric properties, evidence-base, clinical utility

    Empirical support for the recovery utility of 12-step mutual-help organizations (MHOs) has led to increased investigation of how such organizations confer benefit. The Twelve Promises of Alcoholics Anonymous (AA) feature prominently in 12-step philosophy and culture and are one of the few documented explications of the cognitive, affective, and behavioral benefits that members might accrue. This study investigated the psychometric properties of a measure of AA's Twelve Promises and examined whether it mediated the effect of 12-step participation on abstinence. Young adults (N=302, M age 20.4 [1.6], range 18-25; 27% female; 95% White) enrolled in an addiction treatment effectiveness study completed assessments at intake and 3-, 6-, and 12-months post treatment including a 26-item, Twelve Promises Scale (TPS). Factor analyses examined the TPS' psychometrics and lagged mediational analyses tested the TPS as a mechanism of behavior change. Robust principal axis factoring extraction with Varimax rotation revealed a 2-factor solution explaining 45-58% of the variance across three administrations ("Psychological Wellbeing"=26-39%; "Freedom from Craving=17-21%); internal consistency was high (alpha=.83-.93). Both factors were found to increase in relation to greater 12-step participation, but significant mediation was found only for the Freedom from Craving factor explaining 21-34% of the effect of 12-step participation in increasing abstinence. The TPS shows potential as a conceptually relevant, and psychometrically sound measure and may be useful in helping elucidate the extent to which the Twelve Promises emerge as an independent benefit of 12-step participation and/or explain SUD remission and recovery.

    Full Text Available This study analyzed the psychometric properties of the second version of the Assessment Scale for Body Dysmorphic Disorder (AS-BDD. It is a scale of self-report, with 40 items, developed to evaluate 3 dimensions of Body Dysmorphic Disorder (BDD: (a excessive concern with a minor or imagined flaw in his/her personal physical characteristics, (b significant clinical suffering and functional damage in important areas of life, and (c such concern is not better explained by another disorder. The construct analysis by judges indicated accordance in 35 items which were answered by 30 patients diagnosed with BDD and 400 university students. The validity of criterion measures indicated ability to discriminate the items among the individuals of both sampled groups. The exploratory factor analysis suggested a unidimensional structure of the scale which allows to measuring "excessive concern with a minor or imagined flaw in his/her personal physical characteristics and the functional damages in different areas of life". The withheld items have shown excellent internal consistency. Cut point definitions and the ability to discriminate other disorders should be further studied.Este estudo analisou as propriedades psicométricas da segunda versão da Escala de Avaliação do Transtorno Dismórfico Corporal - EA-TDC, de auto-relato, 40 itens, desenvolvidos para avaliar três critérios do Transtorno Dismórfico Corporal caracterizado por: preocupação excessiva com um imaginado defeito na aparência; sofrimento clinicamente significativo e prejuízo funcional em campos importantes da vida; a preocupação não é melhor explicada por outro transtorno.

    The aim was to develop an instrument to assess undergraduate nursing students' experience of service-learning to reveal benefits and identify service-learning as a professional value that leads to civic and social responsibility. Service-learning is a teaching and learning approach that integrates academic learning with experiential community-centered foci. It provides structured opportunities for reflection on broader social and cultural dimensions of health. There is no valid and reliable instrument to measure service-learning experience of nursing students. A psychometric evaluation was conducted through item analysis, validity, and reliability. Face validity agreement was 80 percent; the content validity index was adjusted until 1 was achieved for each item. Two factors explained 58.64 percent of the total variance. Cronbach's α was .940 for the skills subscale and .932 for the personal insight subscale. The inventory demonstrated strong psychometric properties. Future research should focus on replication on diverse populations.

    The STAT is an interactive screening measure for autism that assesses behaviors in the areas of play, communication, and imitation skills. In Study 1, signal detection procedures were employed to identify a cutoff score for the STAT using developmentally matched groups of 2-year-old children with autism and with nonspectrum disorders. The resulting cutoff yielded high sensitivity, specificity, and predictive values for the development sample as well as for an independent validation sample. Study 2 examined psychometric properties of the STAT and revealed acceptable levels of interrater agreement, test-retest reliability, and agreement between STAT risk category and ADOS-G classification. The STAT demonstrates strong psychometric properties and shows promising utility as a Level 2 screening measure for autism.

  4. Analysis of the Psychometric Properties of a Parental Alienation Scale

    Paula Inez Cunha Gomide

    Full Text Available Abstract The development of forensic evaluation scales is fundamental. This study's purpose was to explore the psychometric properties of a parental alienation scale. Forensic technicians completed 193 scales concerning parents involved in a lawsuit: 48 families with at least one parent indicated as the alienator (group A and 48 families with no parental alienation claim (group B. The scale consisted of five categories and 69 items: denying access to the child; derogatory comparisons; emotional manipulation; behavior of parent and child during assessment. The results show Cronbach's alpha = .965 and split-half = .745; KMO = .884 and Bartlett's sphericity test ( p < .001. Concurrent criterion validity applied to data showed that the scale is able to distinguish between the alienator and target parent. The results showed significant and consistent standards in the instrument's psychometric characteristics.

  5. Calculating Speed of Sound

    Sound is an emerging source of renewable energy but it has some limitations. The main limitation is, the amount of energy that can be extracted from sound is very less and that is because of the velocity of the sound. The velocity of sound changes as per medium. If we could increase the velocity of the sound in a medium we would be probably able to extract more amount of energy from sound and will be able to transfer it at a higher rate. To increase the velocity of sound we should know the speed of sound. If we go by the theory of classic mechanics speed is the distance travelled by a particle divided by time whereas velocity is the displacement of particle divided by time. The speed of sound in dry air at 20 °C (68 °F) is considered to be 343.2 meters per second and it won't be wrong in saying that 342.2 meters is the velocity of sound not the speed as it's the displacement of the sound not the total distance sound wave covered. Sound travels in the form of mechanical wave, so while calculating the speed of sound the whole path of wave should be considered not just the distance traveled by sound. In this paper I would like to focus on calculating the actual speed of sound wave which can help us to extract more energy and make sound travel with faster velocity.

    To systematically review the psychometric evidence on the 2-minute walk test (2MWT). Electronic searches of databases including MEDLINE, CINAHL, Academic Search Premier, SPORTDiscus, PsycINFO, EMBASE, the Cochrane Library, and DARE were done until February 2014 using a combination of subject headings and free texts. Studies were included if psychometric properties of the 2MWT were (1) evaluated; (2) written as full reports; and (3) published in English language peer-reviewed journals. A modified consensus-based standard for the selection of health measurement instruments checklist was used to rate the methodological quality of the included studies. A quality assessment for statistical outcomes was used to assess the measurement properties of the 2MWT. Best-evidence synthesis was collated from 25 studies of 14 patient groups. Only 1 study was found that examined the 2MWT in the pediatric population. The testing procedures of the 2MWT varied across the included studies. Reliability, validity (construct and criterion), and responsiveness of the 2MWT also varied across different patient groups. Moderate to strong evidence was found for reliability, convergent validity, discriminative validity, and responsiveness of the 2MWT in frail elderly patients. Moderate to strong evidence for reliability, convergent validity, and responsiveness was found in adults with lower limb amputations. Moderate to strong evidence for validity (convergent and discriminative) was found in adults who received rehabilitation after hip fractures or cardiac surgery. Limited evidence for the psychometric properties of the 2MWT was found in other population groups because of methodological flaws. There is inadequate breadth and depth of psychometric evidence of the 2MWT for clinical and research purposes-specifically, minimal clinically important changes and responsiveness. More good-quality studies are needed, especially in the pediatric population. Consensus on standardized testing procedures of

    2009-01-01

    Objective To conduct a multimethod psychometric evaluation to refine the Children's Somatization Inventory (CSI) and to investigate its dimensionality. Method The CSI was administered to 876 pediatric patients with chronic abdominal pain at their initial visit to a pediatric gastroenterology clinic. Tools from three psychometric models identified items that most effectively measured the construct of somatization and examined its dimensionality. Results Eleven statistically weak items were identified and removed, creating a 24-item CSI (CSI-24). The CSI-24 showed good psychometrics according to the three measurement models and correlated.99 with the original CSI. The CSI-24 has one dominant general factor but is not strictly unidimensional. Conclusions The CSI-24 is a reliable and psychometrically sound refinement of the original CSI. Findings are consistent with the view that somatization has a strong general factor that represents a continuum of symptom reporting, as well as minor components that represent specific symptom clusters in youth with chronic abdominal pain.

    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.

    There is widespread need for the inclusion of service satisfaction measures in mental health services evaluation. The current paper introduces the Service Satisfaction Scale (SSS), a practical and freely available measure of global youth and adult caregiver service satisfaction. The development process, as well as results from a comprehensive psychometric evaluation in a large sample of clinically referred youth (N = 490) receiving home-based care, and their caregivers (N = 383), are presented. Multiple models for psychometric analyses were used including classical test theory, item response theory, and confirmatory factor analysis. As expected, SSS total scores were negatively skewed but the measure displayed otherwise adequate scale characteristics for both the youth and caregiver versions. Thus, the SSS is a brief and psychometrically sound instrument for measuring global satisfaction in home-based mental health service settings. It has several advantages compared to existing measures including brevity, parallel youth and caregiver forms, availability at no cost, and its development on a large sample of youth and caregivers with rigorous psychometric methodology.

    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.

    This study assessed the specificity and sensitivity of two commonly used psychometric methods to assess ARFID in children. To achieve this, a sample of 329 mothers and one father completed the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) and the Child Food Neophobia Scale (CFNS). A Receiver Operating Characteristic (ROC) analysis indicated that both measures were able to successfully differentiate a known clinical sample from those of typically developing population. Although the BPFAS was more accurate at differentiating ARFID from the general population, the CFNS was acceptable and on some metrics better than its longer counterpart. The ability of a food neophobia scale to differentiate clinical and population samples, and detect gradation of food avoidance within the population sample, suggests that the multitude of psychometric measures available may be measuring similar constructs. Therefore, confidence can be expected in cross-site comparisons despite each using different psychometric measures of food avoidance in children. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The purpose of this study was to describe the psychometric testing of the Basic Physical Capability Scale. The study was a secondary data analysis of combined data sets from three studies. Study participants included 93 older adults, recruited from 2 acute-care settings and 110 older adults living in long-term care facilities. Rasch analysis was used for the testing of the measurement model. There was some support for construct validity based on the fit of the items to the scale across both samples. In addition, there was support for hypothesis testing as physical function was significantly associated with physical capability. There was evidence for internal consistency (Alpha coefficients of .77-.83) and interrater reliability based on an intraclass correlation of .81. This study provided preliminary support for the reliability and validity of the Basic Physical Capability Scale, and guidance for scale revisions and continued use.

    The paper provides a survey of 18 years' progress that my colleagues, students (both former and current) and I made in a prominent research area in Psychometrics-Computerized Adaptive Testing (CAT). We start with a historical review of the establishment of a large sample foundation for CAT. It is worth noting that the asymptotic results were derived under the framework of Martingale Theory, a very theoretical perspective of Probability Theory, which may seem unrelated to educational and psychological testing. In addition, we address a number of issues that emerged from large scale implementation and show that how theoretical works can be helpful to solve the problems. Finally, we propose that CAT technology can be very useful to support individualized instruction on a mass scale. We show that even paper and pencil based tests can be made adaptive to support classroom teaching.

    2013-12-01

    Full Text Available The Gilliam Asperger’s Disorder Scale (GADS is a norm-referenced assessment designed to help professionals in Asperger Syndrome (AS diagnosis. This scale is used to evaluate subjects between 3 and 22 years old and it can be completed by anyone who has regular contact with a subject with AS. The only known psychometric studies with positive results are those of the normative sample. Thus this research attempts to explain whether GADS retains the psychometric properties of the normative sample when applied to the Chilean population with AS. To this purpose it was selected a probabilistic intentional sample compose of 36 subjects in the pilot phase and 111 subjects in the final phase. The subscales obtained a Cronbach’s alpha between 0,73 and 0,87, while the global scored 0,92. It was carried out an exploratory factor analysis, thought which it was obtained a factor solution of 8 in the final phase. The results obtained allow to conclude that GADS has adequate psychometric properties, which means GADS is a valid and reliable instrument to be applied to Chilean population.
