    Full Text Available Abstract Background Country by country similarities and differences in physical therapy practice exists. Therefore, before updates in practice can be provided, such as trainings in evidence-based practice, it is necessary to identify the profile and nature of practice in a given country or setting. Following a search of the international literature, no appropriate tool was identified to collect and establish data to create the profile of physical therapy practice in the Philippines. We therefore developed, validated and pilot tested a survey instrument which would comprehensively describe the practice of physical therapy in the Philippines Findings We used a mixed methods design to answer our study aims. A focus group interview was conducted among a group of physical therapists to establish the content and contexts of items to be included in the survey instrument. Findings were amalgamated with the information from the literature on developing survey instruments/questionnaires. A survey instrument was drafted and named as the Physical Therapy Profile Questionnaire (PTPQ. The PTPQ was then validated and pilot tested to a different group of physical therapists. The final version consisted of five separate parts namely (A General information and demographics, (B Practice Profile, (C Treatment Preferences, (D Bases for clinical work and (E Bases for educational/research work. At present the PTPQ is relevant to the Philippines and could be used by any country which has a similar nature of practice with the Philippines. Conclusion The Physical Therapy Practice Questionnaire (PTPQ was shown to have good face and content validity among the Filipino physical therapists and their context of practice. It has also been found to be useful, easy to administer tool and in a format appealing to respondents. The PTPQ is expected to assist comprehensive data collection to create a profile of physical therapy practice in the Philippines.

    Method validation is a critical prerequisite to performing analytical methods in the laboratory. A given analytical method is validated for a specific matrix or matrices. If the matrix to be tested is not included in the original scope of method validation, a validation must be performed to determine if the method is applicable to that particular matrix. A number of organizations, such as AOAC and ISO, publish peer-reviewed methods for cross-industry matrices, whereas others, such as AOCS and AACC, are focused on specific industry segments (fats/oils and cereal grains). When no validated method is available for the analyte of interest, method development and validation must first be performed to ensure that correct identification and quantification of the analyte are being observed and measured. Development of a new method requires an understanding of the chemistry and properties of the analyte to be tested, as well as the various types of instrumentation currently available. Method development and improvement is a continuous process, as technology advances and new instrumentation and techniques become available. This paper addresses some of the decisions related to method development but will primarily focus on validation as it applies to compositional testing of foods, crops, and commodities, the factors that determine method selection, and how extensive the validation need be.

    This is a report of the results of phasor measurement unit (PMU) laboratory development and testing done at the Centre for Electric Technology (CET), Technical University of Denmark (DTU). Analysis of the PMU performance first required the development of tools to convert the DTU PMU data into IEEE...... standard, and the validation is done for the DTU-PMU via a validated commercial PMU. The commercial PMU has been tested from the authors' previous efforts, where the response can be expected to follow known patterns and provide confirmation about the test system to confirm the design and settings....... In a nutshell, having 2 PMUs that observe same signals provides validation of the operation and flags questionable results with more certainty. Moreover, the performance and accuracy of the DTU-PMU is tested acquiring good and precise results, when compared with a commercial phasor measurement device, PMU-1....

    Understanding language development is incomplete without recognizing children's sociocultural environments, including adult beliefs about language development. Yet there is a need for data supporting valid inferences to assess these beliefs. The current study investigated the psychometric properties of data from a survey (MODeL) designed to explore beliefs in the popular culture, and their alignment with more formal theories. Support for the content, substantive, structural, generalizability, and external aspects of construct validity of the data were investigated. Subscales representing Behaviorist, Cognitive, Nativist, and Sociolinguistic models were identified as dimensions of beliefs. More than half of the items showed a high degree of consensus, suggesting culturally-transmitted beliefs. Behaviorist ideas were most popular. Bilingualism and ethnicity were related to Cognitive and Sociolinguistic beliefs. Identifying these beliefs may clarify the nature of child-directed speech, and enable the design of language intervention programs that are congruent with family and cultural expectations.

    Over recent years the role of biomarkers in anticancer drug development has expanded across a spectrum of applications ranging from research tool during early discovery to surrogate endpoint in the clinic. However, in Europe when biomarker measurements are performed on samples collected from subjects entered into clinical trials of new investigational agents, laboratories conducting these analyses become subject to the Clinical Trials Regulations. While these regulations are not specific in their requirements of research laboratories, quality assurance and in particular assay validation are essential. This review, therefore, focuses on a discussion of current thinking in biomarker assay validation. Five categories define the majority of biomarker assays from 'absolute quantitation' to 'categorical'. Validation must therefore take account of both the position of the biomarker in the spectrum towards clinical end point and the level of quantitation inherent in the methodology. Biomarker assay validation should be performed ideally in stages on 'a fit for purpose' basis avoiding unnecessarily dogmatic adherence to rigid guidelines but with careful monitoring of progress at the end of each stage. These principles are illustrated with two specific examples: (a) absolute quantitation of protein biomarkers by mass spectrometry and (b) the M30 and M65 ELISA assays as surrogate end points of cell death.

    Full Text Available Objectives. Strong aversions to acupuncture have been an obstacle to understanding its intrinsic action of acupuncture. Thus, it is necessary to evaluate the nature and extent of fear of acupuncture treatment. Our study aims to develop and validate an instrument that evaluates a patient’s fear of acupuncture treatment. Methods. We have developed an acupuncture fear scale, a 16-item instrument which assesses the acupuncture fear score and uses it to survey 275 participants in South Korea, thus testing the reliability and validity of the instrument. Results. Internal consistency was high (Cronbach’s alpha = 0.935. Test-retest reliability (Spearman’s rank correlation coefficient among 33 participants out of 275 ranged from 0.565 to 0.797 (P<0.001. Principal component analysis revealed two factors accounting for 68% of the variance, which are painful sensation and possible adverse events, respectively. The acupuncture fear scale was positively correlated with the total of fear of pain questionnaire-III (r=0.423, P<0.001. Conclusions. The acupuncture fear scale can be a valid and reliable instrument that can measure fear of acupuncture treatment. These results strongly suggest that it would be a clinically useful tool to assess fear of acupuncture in the acupuncture clinic setting and an important instrument to understand the complex social-behavioral component of acupuncture modality.

    Full Text Available In Nigeria, it seems there is sparse of indigenous measure of emotional intelligence. Therefore, this research fills a gap in literature by developing a valid and reliable indigenous scale. To achieve this, the author combined the Bar-On and Goleman’s models of emotional intelligence. In Study 1, 255 items were generated and were reduced to 198 based on expert advice. At the end of several analyses, 52 items were retained. These items were put in a questionnaire form and administered to 850 students in a university. The author determined the factorial validity of the scale using a sample of 834 participants who returned the scale. The scale (using varimax rotation method was then subjected to principal component analysis and 40 items were retained in a 7 well defined factor structure. The factors/dimensions include interpersonal skill (r = .77, empathetic response (r = .73, stress tolerance (r = .69, optimism (r = .75, assertiveness (r = .78, problem solving (r = .74 and flexibility (r = .80. The scale has convergent validity because of its positive relationship with empathy (r = .67 and social intelligence (r = .79 and negative relationships with aggression (r = -.41 and impulsiveness (r = -.32. A test re-test reliability of .79 was also established for the scale.

    This study developed and evaluated the Nurse Codependency Questionnaire (NCQ) and generated initial estimates of the stability and internal consistency of responses for the questionnaire. An initial pool of 95 items, reflective of four domains of codependency, was generated from the codependency literature using a domain-referenced approach. Seven expert judges from the nursing and codependency fields calculated the content validity index (CVI) as > .80. Items were critiqued for relevance, clarity, and predicted direction of each item's correlation with the total codependency score. A convenience sample of 547 male and female nurses from Texas was recruited from a variety of professional settings to test the NCQ. Evidence of reliability and validity was sought through the use of principal factor analysis (PFA) techniques and correlation analysis. The specific domains of "codependent caretaking" and "lack of voice" represented two of the four hypothesized domains that were supported by factor analysis. Data screening and item analysis resulted in a final sample of 24 items. Test-retest reliability was .90 and internal consistency reliability was .80 for the entire scale. Reliability estimates for the "codependent caretaking" and "lack of voice" scales were .65 and .59, respectively for test-retest; and .81 and .64, respectively for internal consistency. Known groups validity was supported by each of the factors' ability to discriminate between binge and nonbinge eaters. The NCQ may be useful for identifying codependency within the nursing profession. Research is needed to determine the external factors that influence the overt expression of nurse codependency. Screening for nurse codependency may contribute to the health of the profession by providing a means for anticipatory guidance and early intervention.

    Full Text Available Newborns and infants are often exposed to painful procedures during hospitalization. Several different scales have been validated to assess pain in specific populations of pediatric patients, but no single scale can easily and accurately assess pain in all newborns and infants regardless of gestational age and disease state. A new pain scale was developed, the COVERS scale, which incorporates 6 physiological and behavioral measures for scoring. Newborns admitted to the Neonatal Intensive Care Unit or Well Baby Nursery were evaluated for pain/discomfort during two procedures, a heel prick and a diaper change. Pain was assessed using indicators from three previously established scales (CRIES, the Premature Infant Pain Profile, and the Neonatal Infant Pain Scale, as well as the COVERS Scale, depending upon gestational age. Premature infant testing resulted in similar pain assessments using the COVERS and PIPP scales with an r=0.84. For the full-term infants, the COVERS scale and NIPS scale resulted in similar pain assessments with an r=0.95. The COVERS scale is a valid pain scale that can be used in the clinical setting to assess pain in newborns and infants and is universally applicable to all neonates, regardless of their age or physiological state.

    Full Text Available Human that has psycho-socio-cultural identity is invaded in an insensitive interaction with society in which he lives. The interaction continues from childhood to adolescence and adulthood. One of the main factors of the interaction is to have friends and to exist in social environment. The person constantly leagues together new friends, influences them, and is impressed by them during both childhood period and adolescence and adulthood period. However, the friend relationships that one have throughout his life, can create some problems from time to time. At this point, it is seen that the main parts of the national studies related to the subject have been commonly carried out so as to analyze the peer relations of the students at primary or secondary school. In this sense, the starting point of this study consists of the problems that students face in their university peer- groups. Therefore analyzing this problem necessitates developing a new data gathering tool that enables descriptive survey. By doing so, it is through that this scale will be used by researchers in order to put forward the factors related to the friend pressure levels of students and to determine the factors related to the friend pressure levels of the students. By developing a peer pressure scale for university students, the aim of the study is to show the usability of the scale within the scope of validity and reliability. The study was conducted on 450 university students training at the Faculty of Education in Rize University and Fatih Faculty of Education in Karadeniz Technical University. The study group consist of 188 men (42% and 262 girl (58%. In the scale development process, firstly, twelve students selected from different classes and departments on Fatih Faculty of Education in Karadeniz Technical University. Then, focus group discussions were interviewed. For using discussions, a semi-structured interview form was developed. Focused group is shared ideas

  15. Methods for developing and validating survivability distributions

    Williams, R.L.

    1993-10-01

    A previous report explored and discussed statistical methods and procedures that may be applied to validate the survivability of a complex system of systems that cannot be tested as an entity. It described a methodology where Monte Carlo simulation was used to develop the system survivability distribution from the component distributions using a system model that registers the logical interactions of the components to perform system functions. This paper discusses methods that can be used to develop the required survivability distributions based upon three sources of knowledge. These are (1) available test results; (2) little or no available test data, but a good understanding of the physical laws and phenomena which can be applied by computer simulation; and (3) neither test data nor adequate knowledge of the physics are known, in which case, one must rely upon, and quantify, the judgement of experts. This paper describes the relationship between the confidence bounds that can be placed on survivability and the number of tests conducted. It discusses the procedure for developing system level survivability distributions from the distributions for lower levels of integration. It demonstrates application of these techniques by defining a communications network for a Hypothetical System Architecture. A logic model for the performance of this communications network is developed, as well as the survivability distributions for the nodes and links based on two alternate data sets, reflecting the effects of increased testing of all elements. It then shows how this additional testing could be optimized by concentrating only on those elements contained in the low-order fault sets which the methodology identifies.

    One of the agendas for addressing environmental protection in construction is to reduce impacts and make the construction activities more sustainable. This important consideration has generated several research interests within the construction industry, especially considering the construction damaging effects on the ecosystem, such as various forms of environmental pollution, resource depletion and biodiversity loss on a global scale. Using Partial Least Squares-Structural Equation Modeling technique, this study validates environmental sustainability (ES) construct in the context of large construction firms in Malaysia. A cross-sectional survey was carried out where data was collected from Malaysian large construction firms using a structured questionnaire. Results of this study revealed that business innovativeness and new technology are important in determining environmental sustainability (ES) of the Malaysian construction firms. It also established an adequate level of internal consistency reliability, convergent validity and discriminant validity for each of this study's constructs. And based on this result, it could be suggested that the indicators for organisational innovativeness dimensions (business innovativeness and new technology) are useful to measure these constructs in order to study construction firms' tendency to adopt environmental sustainability (ES) in their project execution.

    In this paper, each component of code development and validation system, i.e. IVS and Mercurial will be introduced and Redmine, the integrated platform of IVS and Mercurial, will be explained later. Integrated TH code validation system, IVS and code development and management environment are constructed. The code validation could be achieved by a comparison of results with corresponding experiments. The development of thermal-hydraulic (TH) system code for nuclear reactor requires much time and effort, also for its validation and verification(V and V). In previous, TASS/SMR-S code (hereafter TASS) for SMART is developed by KAERI through V and V process. On the way of code development, the version control of source code has great importance. Also, during the V and V process, the way to reduce repeated labor- and time-consuming work of running the code before releasing new version of TH code, is required. Therefore, the integrated platform for TH code development and validation environment is constructed. Finally, Redmine, the project management and issue tracking system, is selected as platform, Mercurial (hg) for source version control and IVS (Integrated Validation System) for TASS is constructed as a prototype for automated V and V. IVS is useful before release a new code version. The code developer can validate code result easily using IVS. Even during code development, IVS could be used for validation of code modification. Using Redmine and Mercurial, users and developers can use IVS result more effectively.

    The objective of this study was to develop and validate a French-language questionnaire measuring stereotypes related to exercise in cancer patients: The Cancer Exercise Stereotypes Scale (CESS). Four successive steps were carried out with 806 participants. First, a preliminary version was developed on the basis of the relevant literature and qualitative interviews. A test of clarity then led to the reformulation of six of the 30 items. Second, based on the modification indices of the first confirmatory factorial analysis, 11 of the 30 initial items were deleted. A new factorial structure analysis showed a good fit and validated a 19-item instrument with five subscales. Third, the stability of the instrument was tested over time. Last, tests of construct validity were conducted to examine convergent validity and discriminant validity. The French-language CESS appears to have good psychometric qualities and can be used to test theoretical tenets and inform intervention strategies on ways to foster exercise in cancer patients.

    Full Text Available Reliable and valid measures of children's and adolescents' social emotional competence (SEC are necessary to develop in order to assess their social emotional development and provide appropriate intervention in child and adolescent development. A pool of 25 items was created for the Social Emotional Competence Questionnaire (SECQ that represented five dimensions of SEC: self-awareness, social awareness, self-management, relationship management and responsible decision-making. A series of four studies are reported relating to the development and validation of the measure. Confirmatory factor analyses of the responses of 444 fourth-graders showed an acceptable fit of the model. The model was replicated with another 356 secondary school students. Additional studies revealed good internal consistency. The significant correlations among the five SEC components and academic performance provided evidence for the predictive validity of the instrument. With multiple samples, these results showed that the scale holds promise as a reliable, valid measure of SEC.

    2008-11-01

    This article outlines the development of a 10-item measure of workplace ostracism. Using 6 samples (including multisource and multiwave data), the authors developed a reliable scale with a unidimensional factor structure that replicated across 4 separate samples. The scale possessed both convergent and discriminant validity, and criterion-related validity was demonstrated through the scale's relation with basic needs, well-being, job attitudes, job performance, and withdrawal. Overall, the present study suggests that the Workplace Ostracism Scale is a reliable and valid measure and that the workplace ostracism construct has important implications for both individuals and organizations.

    2006-12-01

    After the paper by Mayo, White, and Eysenck in 1978, a considerable number of papers studied the so-called sun-sign-effect predicted by astrology: people born with the sun in a positive sign are supposed to be extraverted, and those with the sun in a negative sign are supposed to be introverted. In these papers, researchers used ad hoc questionnaires with a few questions related to belief, knowledge, experience, or attitude toward astrology. However, an appropriate inventory with known psychometric properties has yet to be developed to assess the belief in astrology. In the present paper, the Belief in Astrology Inventory is presented with some psychometric data. The participants were 743 undergraduates studying Psychology and Social Sciences at a university in Spain. Correlation of scores on Belief in Astrology and Extraversion was small but significant (r = .22; r2 = .04) for positive sun-sign participants. This value accounts for negligible common variance. Women had significandy higher scores on the inventory than men.

    This article outlines the development and validation of the Multidimensional Motivational Climate Observation System (MMCOS). Drawing from an integration of the dimensions of the social environment emphasized within achievement goal theory and self-determination theory (as assumed within Duda's [2013] conceptualization of "empowering" and "disempowering" climates), the MMCOS was developed to enable an objective assessment of the coach-created motivational environment in sport. Study 1 supported the initial validity and reliability of the newly developed observation system. Study 2 further examined the interobserver reliability and factorial structure of the MMCOS. Study 3 explored the predictive validity of the observational system in relation to athletes' reported basic psychological need satisfaction. Overall, the results of these studies provide preliminary support for the inter- and intraobserver reliability, as well as factorial and predictive validity of the MMCOS. Suggestions for the use of this observational system in future research in sport are provided.

    Alcohol myopia theory conceptualizes the ability of alcohol to narrow attention and how this demand on mental resources produces the impairments of self-inflation, relief, and excess. The current research was designed to develop and validate a scale based on this framework. People who were alcohol users rated items representing myopic experiences arising from drinking episodes in the past month. In Study 1 (N = 260), the preliminary 3-factor structure was supported by exploratory factor analysis. In Study 2 (N = 289), the 3-factor structure was substantiated with confirmatory factor analysis, and it was superior in fit to an empirically indefensible 1-factor structure. The final 14-item scale was evaluated with internal consistency reliability, discriminant validity, convergent validity, criterion validity, and incremental validity. The alcohol myopia scale (AMS) illuminates conceptual underpinnings of this theory and yields insights for understanding the tunnel vision that arises from intoxication.

    The Perceived Leadership Communication Questionnaire (PLCQ) is a short, reliable, and valid instrument for measuring leadership communication from both perspectives of the leader and the follower. Drawing on a communication-based approach to leadership and following a theoretical framework of interpersonal communication processes in organizations, this article describes the development and validation of a one-dimensional 6-item scale in four studies (total N = 604). Results from Study 1 and 2 provide evidence for the internal consistency and factorial validity of the PLCQ's self-rating version (PLCQ-SR)-a version for measuring how leaders perceive their own communication with their followers. Results from Study 3 and 4 show internal consistency, construct validity, and criterion validity of the PLCQ's other-rating version (PLCQ-OR)-a version for measuring how followers perceive the communication of their leaders. Cronbach's α had an average of.80 over the four studies. All confirmatory factor analyses yielded good to excellent model fit indices. Convergent validity was established by average positive correlations of.69 with subdimensions of transformational leadership and leader-member exchange scales. Furthermore, nonsignificant correlations with socially desirable responding indicated discriminant validity. Last, criterion validity was supported by a moderately positive correlation with job satisfaction (r =.31).

    Background Parkinson's disease (PD), a progressive neurodegenerative disease, affects motor and nonmotor functions, leading to severe debility and poor quality of life. Studies have reported the beneficial role of yoga in alleviating the symptoms of PD; however, a validated yoga module for PD is unavailable. This study developed and validated an integrated yoga module(IYM) for PD. Methods The IYM was prepared after a thorough review of classical yoga texts and previous findings. Twenty experienced yoga experts, who fulfilled the inclusion criteria, were selected validating the content of the IYM. A total of 28 practices were included in the IYM, and each practice was discussed and rated as (i) not essential, (ii) useful but not essential, and (iii) essential; the content validity ratio (CVR) was calculated using Lawshe's formula. Results Data analysis revealed that of the 28 IYM practices, 21 exhibited significant content validity (cut-off value: 0.42, as calculated by applying Lawshe's formula for the CVR). Conclusions The IYM is valid for PD, with good content validity. However, future studies must determine the feasibility and efficacy of the developed module.

    The Actual Curriculum Development Practices Instrument (ACDP-I) was developed and the factorial validity of the ACDP-I was tested (n = 107) using exploratory factor analysis procedures in the earlier work of [1]. Despite the ACDP-I appears to be content and construct valid instrument with very high internal reliability qualities for using in Malaysia, the accumulated evidences are still needed to provide a sound scientific basis for the proposed score interpretations. Therefore, the present study addresses this concern by utilising the confirmatory factor analysis to further confirm the theoretical structure of the variable Actual Curriculum Development Practices (ACDP) and enrich the psychometrical properties of ACDP-I. Results of this study have practical implication to both researchers and educators whose concerns focus on teachers' classroom practices and the instrument development and validation process.

    2015-04-01

    The development of a self-report instrument to measure antisocial sport behavior, labeled the Antisocial Sport Behavior Survey (ASBS), among large and diverse samples of athletes is reported. Grounded in the social cognitive theory of moral thought and action (Bandura, 1991) and interpersonal theory (Horowitz, 2004), this instrument was developed and tested in accordance with the traditions of construct validity and classical test theory (Gehlback & Brinkworth, 2011). In Phase 1, 272 college-aged competitive sport participants confirmed a theoretical structure of antisocial sport behavior including eight factors (hypercompetitive, intimidating, antagonistic, disrespectful, exploitable, overly accommodating, abetting, and melodramatic). Phase 2 reports on item development and the response structure of the instrument. In Phase 3, evidence of structural validity and external validity for the ASBS was established with 340 college-aged competitive sport participants. The ASBS presents as a promising new instrument to advance understanding of antisocial sport behavior acts committed by competitive athletes.

    Full Text Available Using the Research Development (R&D methodology, the study aimed to develop and validate WebQuests which can be used in literature subjects, particularly in the tertiary level to address the need of literature teachers for pedagogy in the teaching of epic s. The development of the Web Quests was anchored on the Theory of Constructivism. Two groups of experts validated the Web Quests – the literature experts and the ICT experts. The Content Validation Checklist, used by the literature experts, was utilized t o evaluate the content of the Web Quests. Meanwhile, the Rubric for Evaluating Web Quests, used by the ICT experts, was utilized to evaluate the design characteristics of the Web Quests. Computed weighted means using range interval of point scores were emp loyed to treat the data gathered from the evaluation conducted by both group of experts. The Web Quests developed contain five major parts which include: 1 introduction; 2 task; 3 process; 4 evaluation; and 5 conclusion. Based on the findings, the con tent of the Web Quests developed are valid in terms of objectives, activities and instructional characteristics. Likewise, the design characteristics of the Web Quests are excellent in terms of introductions, tasks, processes, resources, evaluations, concl usions and overall designs. Thus, the Web Quests developed are acceptable and can be utilized as instructional materials by literature teachers in the teaching of epics.

    Full Text Available Background: Conscience is the foundation of morality and influences private and professional life. Furthermore, conscience expresses the right image of right and wrong as well as good and bad. It helps nurses to hold their ethical integrity. How acts are led by conscience is different and how it is perceived by health care providers is unclear. Thus, the current study was carried out to develop a valid and reliable instrument to assess perception of nursing conscience. Methods: In a methodological study, primary items of our previous phenomenological research systematic review and previous questionnaire were merged to a single questionnaire. Content face and construct validity was confirmed reliability of the questionnaire was measured by split half and Cronbach α coefficient. Results: Factor analysis determined the five factors of conscience perceived ethical conscience, supervisor conscience, protective conscience, caring conscience and reaction of conscience. Furthermore, the reliability and validity were achieved by statistical tests. Α Cronbach for internal consistency was 0.945 and Guttmann splitting half was r=0.917. Content validity index was more than 90% for each item. Conclusion: The nursing conscience perception questionnaire had 24 items and 5 dimensions and had both validity and reliability, but it needs to be tested over and over to enhance its validity and reliability.

    Boardley, Ian D; Kavussanu, Maria

    2007-10-01

    A sport-specific measure of moral disengagement was developed in 2 studies. In Study 1, a 59-item questionnaire was developed and tested with 308 athletes from 5 team sports. A series of confirmatory factor analyses (CFA) testing different models suggested the model that best fitted the data had 6 first-order factors that could be represented by 1 second-order factor. Study 2 involved 305 athletes from the same 5 sports. CFA confirmed the 6-factor, second-order structure for the final 32-item measure. Results from Study 2 supported the construct validity of the scale, providing evidence for the factorial, concurrent, convergent, and discriminant validity. The Moral Disengagement in Sport Scale (MDSS) is proposed as a valid and reliable measure of moral disengagement for use in the sport context.

    2012-01-01

    Full Text Available The main goal of our research was to develop a new measure of persistence and to assess its construct validity and psychometric proprieties. First, we discuss the history of the psychological construct of persistence, defined here as the tendency to remain engaged in specific goal-related activities, despite difficulties, obstacles, fatigue, prolonged frustration or low perceived feasibility. The developed scale, measuring motivational persistence, contains three-factors: long-term purposes pursuing, current purposes pursuing and recurrence of unattained purposes. The results of the two validation studies conducted, employing both exploratory and confirmatory factor analysis, advocate the hypothesized structure. Also, the Pearson and canonical correlations between the three factors of the new self-report scale and other three related measures (and their factors indicate good levels of convergent and divergent validity of the new scale.

    2011-01-01

    The aim of this study was to investigate the construct validity of the Moral Development Scale for Professionals (MDSP) using structural equation modeling. The instrument is a 12-item self-report instrument, developed in the Scandinavian cultural context and based on Kohlberg's theory. A hypothesized simplex structure model underlying the MDSP was tested through structural equation modeling. Validity was also tested as the proportion of respondents older than 20 years that reached the highest moral level, which according to the theory should be small. A convenience sample of 339 nursing students with a mean age of 25.3 years participated. Results confirmed the simplex model structure, indicating that MDSP reflects a moral construct empirically organized from low to high. A minority of respondents >20 years of age (13.5%) scored more than 80% on the highest moral level. The findings support the construct validity of the MDSP and the stages and levels in Kohlberg's theory.

    Research suggests that employee status, and various status proxies, relate to a number of meaningful outcomes in the workplace. The advancement of the study of status in organizational settings has, however, been stymied by the lack of a validated workplace status measure. The purpose of this manuscript, therefore, is to develop and validate a measure of workplace status based on a theoretically grounded definition of status in organizations. Subject-matter experts were used to examine the content validity of the measure. Then, 2 separate samples were employed to assess the psychometric properties (i.e., factor structure, reliability, convergent and discriminant validity) and nomological network of a 5-item, self-report Workplace Status Scale (WSS). To allow for methodological flexibility, an additional 3 samples were used to extend the WSS to coworker reports of a focal employee's status, provide additional evidence for the validity and reliability of the WSS, and to demonstrate consensus among coworker ratings. Together, these studies provide evidence of the psychometric soundness of the WSS for assessing employee status using either self-reports or other-source reports. The implications of the development of the WSS for the study of status in organizations are discussed, and suggestions for future research using the new measure are offered.

    2012-04-01

    Full Text Available The aim of this paper is to develop a reliable and valid CRM (Customer relationship management scale specifically catering to Indian banking sector. An exhaustive review of literature on CRM was followed by depth interview and questionnaire survey. Exploratory factor analysis was followed by confirmatory factor analysis, which was presented in three forms; the single factor model, covariance model and the structural model. The covariance model shows CRM in Indian banking sector as a multidimensional construct comprising of fact ors namely organizational structure and customer support, service quality, trust, technology, personalization and market orientation. The structural model validates the previously extracted factors along with their indicators. The findings of this study validate the long held belief that CRM is a multidimensional construct and serves as a critical success factor for business performance. Since this study was conducted in context of Indian banking sector, the generalizability of the CRM scale has to be tested in other countries. A fair amount of literature on Indian banking sector dealt with identifying factors explaining the constructs of quality, value or satisfaction. But there is paucity of research pertaining to industry specific CRM scale development and validation. This study is an attempt to bridge this gap in the existing literature. It provides a conceptually validated CRM scale catering to Indian banking sector, which can help the managers in implementing the CRM in an effective manner and also can be used as a tool to identify the major areas requiring attention.

    The objective of this article was to describe 1) the validation of 2 similar but not identical food security modules used to collect data from 2 vulnerable populations, southern Lebanon residents (n = 815) and Palestinian refugees in Lebanon (n = 2501), and 2) the development and validation of an Arab Family Food Security Scale (AFFSS). The surveys used a cluster-randomized sampling design. The 2 food security subscales underwent face and construct validity. In addition, both of these tools and the AFFSS underwent psychometric assessment for internal validity by using statistical methods based on Item Response Theory. The food security questions tested by focus groups were understood and accepted in all regions of Lebanon. The food security subscales and the AFFSS had acceptable levels of internal consistency. The psychometric assessment confirmed that the 7 items of the AFFSS had good internal validity and reasonable reliability with item in-fits from 0.73 to 1.16. Food insecurity was identified among 42% of southern Lebanese and 62% of Palestinian refugee households. The determinants and consequences of food security measured in this study provide additional support for the validity of the modules. Using multivariate logistic regression, the higher the mean monthly income per household member and the higher the educational attainment of the head of household, the lower the risk of food insecurity [ORs (95% CIs): 0.99 (0.98, 0.99) and 0.66 (0.54, 0.80), respectively]. There was a strong significant association between food insecurity and lower food expenditure and lower intake of all food categories except for legumes, which was significantly associated in the opposite direction (P < 0.001). The odds of borrowing money and accepting gifts/donations were significantly higher among moderately and severely food-insecure households (P < 0.000). The AFFSS has been validated within Lebanon and can potentially be extended to other Arab-speaking populations.

    2010-04-01

    The aim of this study was to develop and validate the Disordered Eating Attitude Scale to measure disordered eating attitudes, defined as abnormal beliefs, thoughts, feelings, behaviors, and relationship regarding food. Exploratory factor analysis was performed and internal consistency assessed in a sample of female university students (N=196). Convergent validity was acceptable based on statistically significant correlations with the Eating Attitude Test-26 and Restraint Scale. Known-groups validity was determined by comparing the student sample's mean scores against scores of an eating disorder group (N=51). The Disordered Eating Attitude Scale comprises 25 questions and five subscales explaining 54.3% of total variance. The total scores differentiated student, bulimia, and anorexia groups. The scale should prove useful for evaluating eating attitudes in various population groups and eating disordered patients.

    No validated measures are currently available to assess women's ability to achieve their reproductive intentions, also referred to as "reproductive autonomy." We developed and validated a multidimensional instrument that can measure reproductive autonomy. We generated a pool of 26 items and included them in a survey that was conducted among 1,892 women at 13 family planning and 6 abortion facilities in the United States. Fourteen items were selected through factor analysis and grouped into 3 subscales to form a Reproductive Autonomy Scale: freedom from coercion; communication; and decision-making. Construct validity was demonstrated by a mixed-effects model in which the freedom from coercion subscale and the communication subscale were inversely associated with unprotected sex in the past three months. This new Reproductive Autonomy Scale offers researchers a reliable instrument with which to assess a woman's power to control matters regarding contraceptive use, pregnancy, and childbearing, and to evaluate interventions to increase women's autonomy domestically and globally.

    Background This article reports three studies describing the development and validation of the 12-item Sensitivity to Pain Traumatization Scale (SPTS-12). SPT refers to the anxiety-related cognitive, emotional, and behavioral reactions to pain that resemble the features of a traumatic stress reaction. Methods In Study 1, a preliminary set of 79 items was administered to 116 participants. The data were analyzed by using combined nonparametric and parametric item response theory resulting in a 12-item scale with a one-factor structure and good preliminary psychometric properties. Studies 2 and 3 assessed the factor structure and psychometric properties of the SPTS-12 in a community sample of 823 participants (268 with chronic pain and 555 pain-free) and a clinical sample of 345 patients (126 with chronic post-surgical pain, 92 with other nonsurgical chronic pain, and 127 with no chronic pain) at least 6 months after undergoing coronary artery bypass graft surgery, respectively. Results The final SPTS-12 derived from Study 1 comprised 12 items that discriminated between individuals with different levels of SPT, with the overall scale showing good to very good reliability and validity. The results from Studies 2 and 3 revealed a one-factor structure for chronic pain and pain-free samples, excellent reliability and concurrent validity, and moderate convergent and discriminant validity. Conclusion The results of the three studies provide preliminary evidence for the validity and reliability of the SPTS-12. PMID:28615962

    Nursing is generally perceived as a demanding profession. There is a rising necessity for healthcare administrators to tackle the aspects leading to nurse stress and work burnout as a means towards maintaining a stable and continuous workforce at healthcare institutions.The study aimed at the development of a reliable and valid tool for measuring nursing staff stress and burnout at the University Hospital of King Faisal University, Saudi Arabia. A cross-sectional descriptive study was designed. All registered high nurses working at the hospital were included in the study. The total number accounted for 260 nurses. The study revealed a valid and reliable scale. Such results were indicated through face validity, content validity, and principal component analysis using the varimax rotation for the fifteen statements included in the questionnaire. The PCA explained 56.4% of the variance and concluded 3 main components under which the statements would be categorized. Dimensions were given suitable headings as follows; work aspects, working conditions, and workload. Reliability was assessed and revealed an internal consistency (Cronbach alpha=0.8) and a split-half Spearman-Brown coefficient for unequal length r= 0.79. In conclusion, the study demonstrated a short valid and reliable scale to assess the stressful areas for nurses. The scale is convenient for use by healthcare managers at different medical situations. Further studies are recommended for the use of the tool on representative samples of Saudi nurses.

    Full Text Available Literature shows that some health outcomes (e.g., eating, breathing, and speaking are directly related to posture. Evidence of outcomes mediated by wheelchair seated posture is limited to interface pressure, physical function, and wheelchair skills and safety. This study’s purpose was to develop and validate a rapid, low-burden, paper-pencil assessment of wheelchair seated posture for research use and to test feasibility of its use with a sample of older adults. We used a prospective design and a convenience sample of older adults who were receiving rehabilitation services in a community living center. Forty-nine older wheelchair users participated. Main measures were the Seated Posture Scale (SPS, Modified Ashworth Scale, Barthel Index, Visual Descriptor Scale, scale-content validity index (S-CVI, Cronbach alpha, and test-retest reliability. Rating by six experts yielded the overall content validity score (S-CVI of 0.744. Total SPS score correlated positively with physical function (Barthel Index, r = 0.46, p < 0.001 and negatively with muscle tone (Modified Ashworth Scale, r = –0.44, p = 0.001, supporting SPS construct validity. Internal consistency was 0.66 (Cronbach alpha. Test-retest reliability yielded Pearson product-moment correlations of 0.89 to 0.99. We conclude that the SPS has sufficient preliminary validity and reliability to support its use as an evaluation of wheelchair seated posture in outcomes research.

    Full Text Available Abstract Background Post-traumatic amnesia (PTA is a key symptom of traumatic brain injury (TBI. Accurate assessment of PTA is imperative in guiding clinical decision making. Our aim was to develop and externally validate a short, examiner independent and practical PTA scale, by selecting the most discriminative items from existing scales and using a three-word memory test. Methods Mild, moderate and severe TBI patients and control subjects were assessed in two separate cohorts, one for derivation and one for validation, using a questionnaire comprised of items from existing PTA scales. We tested which individual items best discriminated between TBI patients and controls, represented by sensitivity and specificity. We then created our PTA scale based on these results. This new scale was externally evaluated for its discriminative value using Receiver Operating Characteristic (ROC analysis and compared to existing PTA scales. Results The derivation cohort included 126 TBI patients and 31 control subjects; the validation cohort consisted of 132 patients and 30 controls. A set of seven items was eventually selected to comprise the new PTA scale: age, name of hospital, time, day of week, month, mode of transport and recall of three words. This scale demonstrated adequate discriminative values compared to existing PTA scales on three consecutive administrations in the validation cohort. Conclusion We introduce a valid, practical and examiner independent PTA scale, which is suitable for mild TBI patients at the emergency department and yet still valuable for the follow-up of more severely injured TBI patients.

  7. The Validation of Climate Models: The Development of Essential Practice

    Rood, R. B.

    2011-12-01

    It is possible from both a scientific and philosophical perspective to state that climate models cannot be validated. However, with the realization that the scientific investigation of climate change is as much a subject of politics as of science, maintaining this formal notion of "validation" has significant consequences. For example, it relegates the bulk of work of many climate scientists to an exercise of model evaluation that can be construed as ill-posed. Even within the science community this motivates criticism of climate modeling as an exercise of weak scientific practice. Stepping outside of the science community, statements that validation is impossible are used in political arguments to discredit the scientific investigation of climate, to maintain doubt about projections of climate change, and hence, to prohibit the development of public policy to regulate the emissions of greenhouse gases. With the acceptance of the impossibility of validation, scientists often state that the credibility of models can be established through an evaluation process. A robust evaluation process leads to the quantitative description of the modeling system against a standard set of measures. If this process is standardized as institutional practice, then this provides a measure of model performance from one modeling release to the next. It is argued, here, that such a robust and standardized evaluation of climate models can be structured and quantified as "validation." Arguments about the nuanced meaning of validation and evaluation are a subject about which the climate modeling community needs to develop a standard. It does injustice to a body of science-based knowledge to maintain that validation is "impossible." Rather than following such a premise, which immediately devalues the knowledge base, it is more useful to develop a systematic, standardized approach to robust, appropriate validation. This stands to represent the complexity of the Earth's climate and its

    In this research, we developed a plan for experimental validation of one of the computer models developed for ER process modeling, i. e., the ERAD code. Several candidate surrogate materials are selected for the experiment considering the chemical and physical properties. Molten salt-based pyroprocessing technology is being examined internationally as an alternative to treat spent nuclear fuel over aqueous technology. The central process in pyroprocessing is electrorefining(ER) which separates uranium from transuranic elements and fission products present in spent nuclear fuel. ER is a widely used process in the minerals industry to purify impure metals. Studies of ER by using actual spent nuclear fuel materials are problematic for both technical and political reasons. Therefore, the initial effort for ER process optimization is made by using computer models. A number of models have been developed for this purpose. But as validation of these models is incomplete and often times problematic, the simulation results from these models are inherently uncertain.

    Background Music is an integral part of life in youth, and although it has been acknowledged that musical behavior reflects broader psychosocial aspects of adolescent behavior, no measurement instruments have been specifically designed for assessing musical engagement as an indicator of adolescent wellbeing and/or symptomatology. This study was conducted in order to develop and validate a scale for assessing musical engagement as an indicator of proneness for depression in youth. Method Items were developed based on the literature and a prior grounded theory analysis and three surveys (N = 54, N = 187, N = 211) were conducted to select, refine, test, and validate the items. Scale structure was investigated through interitem correlations, exploratory and confirmatory factor analyses (EFA, CFA), and concurrent validity was tested with correlations to depression and wellbeing. Results The final Healthy-Unhealthy Music Scale (HUMS) consists of 13 items that are divided into Healthy and Unhealthy subscales. Cronbach's alpha coefficients were .78 for Healthy and .83 for Unhealthy. The concurrent validity of the HUMS was confirmed through correlations to wellbeing, happiness and school satisfaction on one hand and depression, rumination, and stress on the other. Conclusions The HUMS is as a promising instrument for screening musical engagement that is indicative of proneness for depression in youth. PMID:26726295

    Investing in financial markets is promoted and protected by the government as an essential economic activity, but can turn into a gambling addiction problem. Until now, few scales have widely been used to identify gambling addicts in financial markets. This study aimed to develop a self-rating scale to distinguish them. In addition, the reliability and validity of the stock addiction inventory (SAI) were demonstrated. A set of questionnaires, including the SAI, south oaks gambling screen (SOGS), and DSM-5 diagnostic criteria, for gambling disorder was completed by 1005 participants. Factor analysis, internal consistency testing, t tests, analysis of variance, and partial correlation analysis were conducted to verify the reliability and validity of SAI. The factor analysis results showed the final SAI consisting of two factors and nine items. The internal consistency and concurrent validity of SAI were verified. The Cronbach's α for the total scale was 0.892, and the SAI and its factors were significantly correlated with SOGS. This study developed a specific scale for financial market investments or trading; this scale proved to be reliable and valid. Our scale expands the understanding of gambling addiction in financial markets and provides a diagnostic reference.

    We have developed and validated a conceptual framework for understanding and teaching organismal homeostasis at the undergraduate level. The resulting homeostasis conceptual framework details critical components and constituent ideas underlying the concept of homeostasis. It has been validated by a broad range of physiology faculty members from community colleges, primarily undergraduate institutions, research universities, and medical schools. In online surveys, faculty members confirmed the relevance of each item in the framework for undergraduate physiology and rated the importance and difficulty of each. The homeostasis conceptual framework was constructed as a guide for teaching and learning of this critical core concept in physiology, and it also paves the way for the development of a concept inventory for homeostasis.

    This study aims to develop a multiple-choice instrument for determining students’ concepts about the photoelectric effect. To develop the instrument, 30 students taking the Modern Physics course were interviewed to determine their misconceptions about the photoelectric effect. These misconceptions were compared with the misconceptions set out in the literature so that a decision could be made to define the questions and distractors to be used in the instrument. The content validity of the inventory was achieved on the basis of the feedback received from ten experts. The inventory was administered to 295 students enrolled in the Physics Teaching and Science Teaching Departments and discrimination index, difficulty index, and point biserial coefficient values were determined for each item. Cronbach’s alpha coefficient was calculated for the whole of the test. The results of the analysis reveal that the inventory is both valid and reliable.

    The climate of school classrooms, shaped by a combination of teacher practices and peer processes, is an important determinant for children's psychosocial functioning and is a primary factor affecting bullying and victimization. Given that there are relatively few theoretically-grounded and validated assessment tools designed to measure the social climate of classrooms, our research team developed an observation tool through participatory action research (PAR). This article details how the assessment tool was designed and preliminarily validated in 18 third-, fourth-, and fifth-grade classrooms in a large urban public school district. The goals of this study are to illustrate the feasibility of a PAR paradigm in measurement development, ascertain the psychometric properties of the assessment tool, and determine associations with different indices of classroom levels of relational and physical aggression.

    To date, there is no validated measure for pain catastrophizing at the daily level. The Pain Catastrophizing Scale (PCS) is widely used to measure trait pain catastrophizing. We sought to develop and validate a brief, daily version of the PCS for use in daily diary studies to facilitate research on mechanisms of catastrophizing treatment, individual differences in self-regulation, and to reveal the nuanced relationships between catastrophizing, correlates, and pain outcomes. After adapting the PCS for daily use, we evaluated the resulting 14 items using 3 rounds of cognitive interviews with 30 adults with chronic pain. We refined and tested the final daily PCS in 3 independent, prospective, cross-sectional, observational validation studies conducted in a combined total of 519 adults with chronic pain who completed online measures daily for 14 consecutive days. For study 1 (N = 131), exploratory factor analysis revealed adequate fit and-unexpectedly-unidimensionality for item responses to the daily PCS. Study 2 (N = 177) correlations indicated adequate association with related constructs (anger, anxiety, pain intensity, depression). Similarly, results for study 3 (N = 211) revealed expected correlations for daily PCS and measures of daily constructs including physical activity, sleep, energy level, and positive affect. Results from complex/multilevel confirmatory factor analysis confirmed good fit to a unidimensional model. Scores on the daily PCS were statistically comparable with and more parsimonious than the full 14-item version. Next steps include evaluation of score validity in populations with medical diagnoses, greater demographic diversity, and in patients with acute pain. This article describes the development and validation of a daily PCS. This daily measure may facilitate research that aims to characterize pain mechanisms, individual differences in self-regulation, adaptation, and nuanced relationships between catastrophizing, correlates, and pain

    Full Text Available BackgroundThere is a growing concern in the field of aesthetic surgery about the need to measure patients' expectations preoperatively. The present study was designed to develop and validate the Expectations of Aesthetic Rhinoplasty Scale (EARS, and to compare expectations between rhinoplasty patients with and without body dysmorphic disorder (BDD.MethodsIn total, 162 college students and 20 rhinoplasty candidates were recruited. The measures included the newly developed EARS, a measure of psychopathology, and demographics. The DSM-IV structured clinical interview for BDD was used to confirm the diagnosis in rhinoplasty patients.ResultsThe EARS was constructed of six items based on their significant content validity. In the scale development phase, Cronbach's alpha was 0.87. The test-retest reliability coefficient of the scale was satisfactory (intraclass correlation coefficient, 0.94; 95% confidence interval, 0.82–0.98 over a four-week period. Scores on the EARS were significantly positively correlated with psychopathological symptoms (r=0.16; P<0.05. Moreover, comparison of EARS scores between BDD (M=25.90, standard deviation [SD]=6.91 and non-BDD rhinoplastic patients (M=15.70, SD=5.27 suggested that BDD patients held significantly higher expectations (P<0.01.ConclusionsThe expectations of aesthetic rhinoplasty patients toward surgery may play a crucial role in their postoperative satisfaction. While the value of patients' expectations is clinically recognized, no empirical study has measured these expectations in a psychometrically sound manner. The current study developed and validated the EARS. It may be easily used as a valid and reliable instrument in clinical and research settings.

  19. The development and validation of the Incivility from Customers Scale.

    Wilson, Nicole L; Holmvall, Camilla M

    2013-07-01

    Scant research has examined customers as sources of workplace incivility, despite evidence suggesting that mistreatment is more common from organizational outsiders, including customers, than from organizational members (Grandey, Kern, & Frone, 2007; Schat & Kelloway, 2005). As an important step in extending the literature on customer incivility, we conducted two studies to develop and validate a measure of this construct. Study 1 used focus groups of retail and restaurant employees (n = 30) to elicit a list of uncivil customer behaviors, based on which we wrote initial scale items. Study 2 used a correlational survey design (n = 439) to pare down the number of scale items to 10 and to garner reliability and validity evidence for the scale. Exploratory and confirmatory factor analyses show that the scale is unidimensional and distinguishable from measures of the related, but distinct, constructs of interpersonal justice and psychological aggression from customers. Reliability analyses show that the scale is internally consistent. Significant correlations between the scale and individuals' job satisfaction, turnover intentions, and general and job-specific psychological strain provide evidence of criterion-related validity. Hierarchical regression analyses show that the scale significantly predicts three of four organizational and personal strain outcomes over and above a workplace incivility measure adapted for customer incivility, providing some evidence of incremental validity. Limitations and future research directions are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    The aim of this study was to develop a screening questionnaire that could distinguish individuals at high risk of smartphone overuse from casual users. The reliability, validity, and diagnostic ability of the Smartphone Overuse Screening Questionnaire (SOS-Q) were evaluated. Preliminary items were assessed by 50 addiction experts on-line, and 28 questions were selected. A total of 158 subjects recruited from six community centers for internet addiction participated in this study. The SOS-Q, Young's internet addiction scale, Korean scale for internet addiction, and Smartphone Scale for Smartphone Addiction (S-Scale) were used to assess the concurrent validity. Construct validity was supported by a six-factor model using an exploratory factor analysis. The internal consistency and the item-total correlations were favorable (α = 0.95, r = 0.35-0.81). The test-retest reliability was moderate (r = 0.70). The SOS-Q showed superior concurrent validity with the highest correlation between the S-Scale (r = 0.76). Receiver operating characteristic curve analysis revealed an area under the curve of 0.877. A cut-off point of 49 effectively categorized addiction high-risk group with a sensitivity of 0.81 and specificity of 0.86. Overall, the current study supports the use of SOS-Q as both a primary and supplementary measurement tool in a variety of settings. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    Key research suggests that empathy is a multidimensional construct comprising of both cognitive and affective components. More recent theories and research suggest even further factors within these components of empathy, including the ability to empathize with others versus the drive towards empathizing with others. While numerous self-report measures have been developed to examine empathy, none of them currently index all of these wider components together. The aim of the present research was to develop and validate the Empathy Components Questionnaire (ECQ) to measure cognitive and affective components, as well as ability and drive components within each. Study one utilized items measuring cognitive and affective empathy taken from various established questionnaires to create an initial version of the ECQ. Principal component analysis (PCA) was used to examine the underlying components of empathy within the ECQ in a sample of 101 typical adults. Results revealed a five-component model consisting of cognitive ability, cognitive drive, affective ability, affective drive, and a fifth factor assessing affective reactivity. This five-component structure was then validated and confirmed using confirmatory factor analysis (CFA) in an independent sample of 211 typical adults. Results also showed that females scored higher than males overall on the ECQ, and on specific components, which is consistent with previous findings of a female advantage on self-reported empathy. Findings also showed certain components predicted scores on an independent measure of social behavior, which provided good convergent validity of the ECQ. Together, these findings validate the newly developed ECQ as a multidimensional measure of empathy more in-line with current theories of empathy. The ECQ provides a useful new tool for quick and easy measurement of empathy and its components for research with both healthy and clinical populations.

    Pediatricians play a key role in the onset and duration of breastfeeding. Although it is known that they lack formal education on this subject, there are currently no validated tools available to assess pediatrician knowledge regarding breastfeeding. To develop and validate a Breastfeeding Knowledge and Skills Questionnaire for Pediatricians. Once the knowledge areas were defined, a representative sample of pediatricians was chosen to carry out the survey. After pilot testing, non-discriminating questions were removed. Content validity was assessed by 14 breastfeeding experts, who examined the test, yielding 22 scorable items (maximum score: 26 points). To approach criterion validity, it was hypothesized that a group of pediatricians with a special interest in breastfeeding (1) would obtain better results than pediatricians from a hospital without a maternity ward (2), and the latter would obtain a higher score than the medical residents of Pediatrics training in the same hospital (3). The questionnaire was also evaluated before and after a basic course in breastfeeding. Breastfeeding experts have an index of agreement of >.90 for each item. The 3 groups (n=82) were compared, finding significant differences between group (1) and the rest. Moreover, an improvement was observed in the participants who attended the breastfeeding course (n=31), especially among those with less initial knowledge. Regarding reliability, internal consistency (KR-20=.87), interobserver agreement, and temporal stability were examined, with satisfactory results. A practical and self-administered tool is presented to assess pediatrician knowledge regarding breastfeeding, with a documented validity and reliability.

The instrument is a 12-item self-report instrument, developed in the Scandinavian cultural context and based on Kohlberg’s theory. A hypothesized simplex structure model underlying the MDSP was tested through structural equation modeling. Validity was also tested as the proportion of respondents older than 20 years that reached the highest moral level, which according to the theory should be small. A convenience sample of 339 nursing students with a mean age of 25.3 years participated. Results confirmed the simplex model structure, indicating that MDSP reflects a moral construct empirically organized from low to high. A minority of respondents >20 years of age (13.5% scored more than 80% on the highest moral level. The findings support the construct validity of the MDSP and the stages and levels in Kohlberg’s theory.Keywords: Kohlberg, scale testing, simplex structure model, structural equation modeling

    To develop and validate a comprehensive, self-administered questionnaire for patients with limited ability to open the mouth, trismus. We derived the Gothenburg Trismus Questionnaire (GTQ) from empirical evidence in the medical literature and interviews with medical experts as well as patients. The draft version was tested in a pilot study (n=18). Patients with a maximal incisal opening (MIO) of ⩽35mm were included. The study comprised patients with benign jaw-related conditions (n=51), patients treated for head and neck (H&N) cancer (n=78) and an age- and gender-matched control group without trismus (n=129). The GTQ instrument was well accepted by the patients, with satisfactory compliance and low rates of missing items. After item reduction, due to items not being conceptually relevant and/or low factor loadings, the GTQ demonstrated high internal consistency (Cronbach's alpha 0.72-0.90), good construct validity and known-group validity. We developed a trismus-specific self-administered questionnaire, the GTQ, that showed good psychometric properties. We suggest this questionnaire, that has clear clinical relevance, to be adopted and used in clinical practice and in research, acting as a screening tool as well as an endpoint in intervention and jaw physiotherapy/rehabilitation studies.

    The development and bicultural validation of the New Sexual Satisfaction Scale (NSSS)--a 20 item, multidimensional, composite measure of sexual satisfaction--is presented. The development of the scale was based on a five-dimension, conceptual model that emphasized the importance of multiple domains of sexual behavior including sexual sensations, sexual awareness and focus, sexual exchange, emotional closeness, and sexual activity. Scale construction and validation were carried out using seven independent samples with over 2,000 participants aged 18 to 55 in Croatia and the United States. Primary data collection was completed using online survey tools. Analyses did not confirm the proposed conceptual framework but suggested a two-dimensional structure focusing on self ("ego-centered") and the other (a "partner- and sexual activity-centered" factor) domains, each containing items representing all five conceptual dimensions. Scale reliability (k = 20) was satisfactory for all samples, and construct validity was confirmed in both cultures. The NSSS was also found to have acceptable one-month stability. It is suggested that the NSSS may be a useful tool for assessing sexual satisfaction regardless of a person's gender, sexual orientation, and relationship status.

    It is clear that high class expertise and effective practice exists within many talent development environments across the world. However, there is also a general consensus that widespread evidence-based policy and practice is lacking. As such, it is crucial to develop solutions which can facilitate effective dissemination of knowledge and promotion of evidence-based talent development systems. While the Talent Development Environment Questionnaire (Martindale et al., 2010 ) provides a method through which this could be facilitated, its ecological validity has remained untested. As such, this study aimed to investigate the real world applicability of the questionnaire through discriminant function analysis. Athletes across ten distinct regional squads and academies were identified and separated into two broad levels, 'higher quality' (n = 48) and 'lower quality' (n = 51) environments, based on their process quality and productivity. Results revealed that the Talent Development Environment Questionnaire was able to discriminate with 77.8% accuracy. Furthermore, in addition to the questionnaire as a whole, two individual features, 'quality preparation' (P < 0.01) and 'understanding the athlete' (P < 0.01), were found to be significant discriminators. In conclusion, the results indicate robust structural properties and sound ecological validity, allowing the questionnaire to be used with more confidence in applied and research settings.

  8. A geomagnetically induced current warning system: model development and validation

    McKay, A.; Clarke, E.; Reay, S.; Thomson, A.

    Geomagnetically Induced Currents (GIC), which can flow in technological systems at the Earth's surface, are a consequence of magnetic storms and Space Weather. A well-documented practical problem for the power transmission industry is that GIC can affect the lifetime and performance of transformers within the power grid. Operational mitigation is widely considered to be one of the best strategies to manage the Space Weather and GIC risk. Therefore in the UK a magnetic storm warning and GIC monitoring and analysis programme has been under development by the British Geological Survey and Scottish Power plc (the power grid operator for Central Scotland) since 1999. Under the auspices of the European Space Agency's service development activities BGS is developing the capability to meet two key user needs that have been identified. These needs are, firstly, the development of a near real-time solar wind shock/ geomagnetic storm warning, based on L1 solar wind data and, secondly, the development of an integrated surface geo-electric field and power grid network model that should allow prediction of GIC throughout the power grid in near real time. While the final goal is a `seamless package', the components of the package utilise diverse scientific techniques. We review progress to date with particular regard to the validation of the individual components of the package. The Scottish power grid response to the October 2003 magnetic storms is also discussed and model and validation data are presented.

    In two studies we develop and validate a Classical--overt or direct--and a Modern--covert or subtle--Sexism Scale concerning attitudes toward women, for a Swedish (Scandinavian) context. Further, we examine whether these two forms of prejudice are distinguishable. Confirmatory factor analyses showed that, although highly correlated, classical and modern sexism are distinguishable. The construct validations showed that men had higher means on modern and classical sexism scores than women, and that our scales were related to other constructs as expected. In a third study, we analyzed the knowledge and the content of cultural stereotypes about women. There were no differences in the knowledge of cultural stereotypes between men and women or between high- and low-sexist individuals. The findings are discussed in relation to previous international studies that examine people's modern and/or classical sexism.

    The development of critical consciousness (CC) has been theorized to be an essential prerequisite for individual and collective action toward changing inequitable social conditions. However, empirically supported instruments intended to measure this important construct have only recently been introduced to the literature. The purpose of this project was to create a brief, psychometrically sound measure of CC. Two studies with over 600 observations provide initial reliability and validity data on the Contemporary Critical Consciousness Measure (CCCM). Results from exploratory and confirmatory factor analyses suggest that the final 19-item CCCM assesses CC associated with racism, classism, and heterosexism and provides a general index of CC. Results support the internal consistency and factor structure of the measure. Expected relationships between the CCCM and existing measures of symbolic racism, classism, and homonegativity provide evidence for the validity of the instrument. Limitations, future directions for research, and counseling implications are discussed.

    The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS). Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies). In 11 independent studies (total N = 2,250), we demonstrate the SINS' psychometric properties. The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults), intrapersonal correlates (e.g., positive affect, depression), and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior). The SINS taps into the more fragile and less desirable components of narcissism. The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures.

    The Geant4 hadronic models cover the entire range of energies required by calorimeters in new and planned experiments. The extension and improvement of the elastic, cascade, parameterized and quark-gluon string models will be discussed. Such improvements include the extension to more particle types, a review and correction of cross sections, and a better treatment of energy and momentum conservation. Concurrent with this development has been a validation program which includes comparisons with double differential cross sections. An ongoing hadronic shower validation will also be discussed which includes the examination of longitudinal shower shapes and the performance of the above models as well as their interaction with electromagnetic processes such as multiple scattering.

    The fundamental and more critical steps that are necessary for the development and validation of QSAR models are presented in this chapter as best practices in the field. These procedures are discussed in the context of predictive QSAR modelling that is focused on achieving models of the highest statistical quality and with external predictive power. The most important and most used statistical parameters needed to verify the real performances of QSAR models (of both linear regression and classification) are presented. Special emphasis is placed on the validation of models, both internally and externally, as well as on the need to define model applicability domains, which should be done when models are employed for the prediction of new external compounds.

    To develop and to test the psychometric properties of the Chinese Health Literacy Scale for Diabetes. Patients with diabetes encounter many challenges when making health decisions in their daily lives, as they have access to many different kinds of health information. Health literacy issues are new topics in Chinese society. Without a valid and reliable instrument in Chinese, it is difficult to measure the level of health literacy and promote the concept of health literacy in Chinese societies. A methodological study with a sample of 137 patients with type 2 diabetes aged 65 years or older. Chinese Health Literacy Scale for Diabetes was developed with reference to the revised Bloom's taxonomy model. Psychometric tests (content validity, item analysis, construct validity, discriminative ability and test-retest reliability) were conducted. Correlations between Chinese Health Literacy Scale for Diabetes and four relevant measures were tested. Cronbach's alpha and alpha if item deleted were calculated to assess internal consistency. Cronbach's alpha for Chinese Health Literacy Scale for Diabetes and its four subscales (remembering, understanding, applying and analysing) were 0·884, 0·885, 0·667, 0·654 and 0·717, respectively. The Chinese Health Literacy Scale for Diabetes was significantly correlated with the Diabetic Knowledge Scale (r = 0·398, p Diabetic Management Self-Efficacy Scale (r = 0·257, p Literacy Scale (r = 0·822, p Literacy Scale for Diabetes as a reliable and valid instrument for measuring the health literacy of Chinese patients with diabetes. We recommend that clinicians use this tool to assess patients' health literacy before conducting any kind of health promotion. © 2012 Blackwell Publishing Ltd.

    Full Text Available OBJECTIVE: The aim of this study was to develop a self-diagnostic scale that could distinguish smartphone addicts based on the Korean self-diagnostic program for Internet addiction (K-scale and the smartphone's own features. In addition, the reliability and validity of the smartphone addiction scale (SAS was demonstrated. METHODS: A total of 197 participants were selected from Nov. 2011 to Jan. 2012 to accomplish a set of questionnaires, including SAS, K-scale, modified Kimberly Young Internet addiction test (Y-scale, visual analogue scale (VAS, and substance dependence and abuse diagnosis of DSM-IV. There were 64 males and 133 females, with ages ranging from 18 to 53 years (M = 26.06; SD = 5.96. Factor analysis, internal-consistency test, t-test, ANOVA, and correlation analysis were conducted to verify the reliability and validity of SAS. RESULTS: Based on the factor analysis results, the subscale "disturbance of reality testing" was removed, and six factors were left. The internal consistency and concurrent validity of SAS were verified (Cronbach's alpha = 0.967. SAS and its subscales were significantly correlated with K-scale and Y-scale. The VAS of each factor also showed a significant correlation with each subscale. In addition, differences were found in the job (p<0.05, education (p<0.05, and self-reported smartphone addiction scores (p<0.001 in SAS. CONCLUSIONS: This study developed the first scale of the smartphone addiction aspect of the diagnostic manual. This scale was proven to be relatively reliable and valid.

    Full Text Available Orientation: The assessment centre (AC is a prominent measurement tool for selection and development.Research purpose: The aim of this study was to determine the construct validity of a one-day development assessment centre (DAC using a convenience sample of 202 managers in a large South African banking institution.Motivation for the study: Although the AC method is popular, it has been widely criticised as to whether it predominantly measures the dimensions it is designed to measure.Research design, approach and method: The fit of the measurement models implied by the dimensions measured was analysed in a quantitative study using an ex post facto correlation design and structural equation modelling.Main findings: Bi-factor confirmatory factor analysis was used to assess the relative contribution of higher-order exercise and dimension effects. Empirical under-identification stemming from the small number of exercises designed to reflect designated latent dimensions restricted the number of DAC dimensions that could be evaluated. Ultimately, only one global dimension had enough measurement points and was analysed. The results suggested that dimension effects explained the majority of variance in the post-exercise dimension ratings.Practical/managerial implications: Candidates’ proficiency on each dimension was used as the basis for development reports. The validity of inferences holds important implications for candidates’ career development and growth.Contribution/value-add: The authors found only one study on construct validity of AC dimensions in the South African context. The present study is the first use the bi-factor approach. This study will consequently contribute to the scarce AC literature in South Africa.

    Decent work is positioned as the centerpiece of the recently developed Psychology of Working Theory (PWT; Duffy, Blustein, Diemer, & Autin, 2016). However, to date, no instrument exists which assesses all 5 components of decent work from a psychological perspective. In the current study, we developed the Decent Work Scale (DWS) and demonstrated several aspects of validity with 2 samples of working adults. In Study 1 (N = 275), a large pool of items were developed and exploratory factor analysis was conducted resulting in a final 15-item scale with 5 factors/subscales corresponding to the 5 components of decent work: (a) physically and interpersonally safe working conditions, (b) access to health care, (c) adequate compensation, (d) hours that allow for free time and rest, and (e) organizational values that complement family and social values. In Study 2 (N = 589), confirmatory factor analysis demonstrated that a 5-factor, bifactor model offered the strongest and most parsimonious fit to the data. Configural, metric, and scalar invariance models were tested demonstrating that the structure of the instrument did not differ across gender, income, social class, and majority/minority racial/ethnic groups. Finally, the overall scale score and 5 subscale scores correlated in the expected directions with similar constructs supporting convergent and discriminant evidence of validity, and subscale scores evidenced predictive validity in the prediction of job satisfaction, work meaning, and withdrawal intentions. The development of this scale provides a useful tool for researchers and practitioners seeking to assess the attainment of decent work among employed adults. (PsycINFO Database Record

    Laboratory ergometers have high costs, becoming inaccessible for most of the population, hence, it is imperative to develop affordable devices making evaluations like cardiorespiratory fitness feasible and easier. The objective of this study was to develop and validate an Automated Step Ergometer (ASE), adjusted according to the height of the subject, for predicting VO2max through a progressive test. The development process was comprised by three steps, the theoretical part, the prototype assembly and further validation. The ASE consists in an elevating platform that makes the step at a higher or lower level as required for testing. The ASE validation was obtained by comparing the values of predicted VO2max (equation) and direct gas analysis on the prototype and on a, treadmill. For the validation process 167 subjects with average age of 31.24 ± 14.38 years, of both genders and different degrees of cardiorespiratory fitness, were randomized and divided by gender and training condition, into untrained (n=106), active (n=24) and trained (n=37) subjects. Each participant performed a progressive test on which the ASE started at the same height (20 cm) for all. Then, according to the subject's height, it varied to a maximum of 45 cm. Time in each stage and rhythm was chosen in accordance with training condition from lowest to highest (60-180 s; 116-160 bpm, respectively). Data was compared with the student's t test and ANOVA; correlations were tested with Pearson's r. The value of α was set at 0.05. No differences were found between the predicted VO2max and the direct gas analysis VO2max, nor between the ASE and treadmill VO2max (p= 0.365) with high correlation between ergometers (r= 0.974). The values for repeatability, reproducibility, and reliability of male and female groups measures were, respectively, 4.08 and 5.02; 0.50 and 1.11; 4.11 and 5.15. The values of internal consistency (Cronbach's alpha) among measures were all >0.90. It was verified that the ASE

    Planning is the critical first stage of metacognition. Although it has long been emphasized theoretically, it has not been the subject of much empirical study due to the lack of a valid assessment tool. Because planning is a metacognitive process, online methods that collect data during task performance would much better capture it. The present study was conducted to develop an online measure of metacognitive planning. Researchers designed a puzzle task that took the form of the popular game Sokoban, and the ratio between planning time and total time of each item was chosen as the metacognitive planning index. The task was administered to a heterogeneous sample of 440 participants composed of college students as well as 5th-, 7th-, and 10th-grade students. The results showed that valid inference could be made from the time ratio score. Cronbach's alpha and test-retest correlation provided robust evidence of reliability of the time ratio score. Confirmatory factor analysis further confirmed its unidimensionality. Validity evidence also supported the use of the time ratio score. After controlling for demographic variables, intelligence, and motivation, the time ratio score still accounted for a significant proportion of variance of Sokoban performance, the Tower of London performance, and academic achievement. The time ratio score was also found to increase with age. Taken together, the results of the study revealed that the time ratio is a psychometrically sound online measure of metacognitive planning. 2015 APA, all rights reserved

    Full Text Available OBJECTIVE: The aim of this study was to develop a self-administered scale based on the special features of smartphone. The reliability and validity of the Smartphone Addiction Inventory (SPAI was demonstrated. METHODS: A total of 283 participants were recruited from Dec. 2012 to Jul. 2013 to complete a set of questionnaires, including a 26-item SPAI modified from the Chinese Internet Addiction Scale and phantom vibration and ringing syndrome questionnaire. There were 260 males and 23 females, with ages 22.9 ± 2.0 years. Exploratory factor analysis, internal-consistency test, test-retest, and correlation analysis were conducted to verify the reliability and validity of the SPAI. Correlations between each subscale and phantom vibration and ringing were also explored. RESULTS: Exploratory factor analysis yielded four factors: compulsive behavior, functional impairment, withdrawal and tolerance. Test-retest reliabilities (intraclass correlations  = 0.74-0.91 and internal consistency (Cronbach's α = 0.94 were all satisfactory. The four subscales had moderate to high correlations (0.56-0.78, but had no or very low correlation to phantom vibration/ringing syndrome. CONCLUSION: This study provides evidence that the SPAI is a valid and reliable, self-administered screening tool to investigate smartphone addiction. Phantom vibration and ringing might be independent entities of smartphone addiction.

    The aim of this study was to develop a self-administered scale based on the special features of smartphone. The reliability and validity of the Smartphone Addiction Inventory (SPAI) was demonstrated. A total of 283 participants were recruited from Dec. 2012 to Jul. 2013 to complete a set of questionnaires, including a 26-item SPAI modified from the Chinese Internet Addiction Scale and phantom vibration and ringing syndrome questionnaire. There were 260 males and 23 females, with ages 22.9 ± 2.0 years. Exploratory factor analysis, internal-consistency test, test-retest, and correlation analysis were conducted to verify the reliability and validity of the SPAI. Correlations between each subscale and phantom vibration and ringing were also explored. Exploratory factor analysis yielded four factors: compulsive behavior, functional impairment, withdrawal and tolerance. Test-retest reliabilities (intraclass correlations  = 0.74-0.91) and internal consistency (Cronbach's α = 0.94) were all satisfactory. The four subscales had moderate to high correlations (0.56-0.78), but had no or very low correlation to phantom vibration/ringing syndrome. This study provides evidence that the SPAI is a valid and reliable, self-administered screening tool to investigate smartphone addiction. Phantom vibration and ringing might be independent entities of smartphone addiction.

    Full Text Available We developed and validated an automated, inexpensive, and continuous multiple-species gas-flux monitoring system that can provide data for a variety of relevant atmospheric pollutants, including O3, CO2, and NOx. Validation consisted of conducting concurrent gas-phase dry-deposition experiments, using both dynamic flux chambers and an eddy-covariance system, in a grassy clearing in the Duke Forest (Chapel Hill, NC. Experiments were carried out in June and September, under a variety of meteorological conditions. Ozone-deposition measurements from the two methods matched very well (4–10% difference in mean flux rate when the leaf-area index (LAI inside the chambers was representative of the average LAI in the field. The dynamic flux chambers can be considered an accurate measurement system under these conditions. CO2 measurements were conducted for one 20 h period, and the flux chamber captured the diurnal trend in CO2 flux well, although the quantity of the data was not sufficient to validate chamber performance. Flux-chamber NOx measurements could be calculated when ambient NOx concentrations were above 1 ppb. Unfortunately, the eddy-covariance system for measuring NOx was not available during this field campaign, so comparisons cannot be made. NOx fluxes were in a reasonable range for the field site.

    Full Text Available In the last 30 years of research of lean manufacturing many different questionnaires was proposed to check the degree of the use of the concept. The set of the items used changed considerably from one investigation to another one. Until now isn’t appreciate a movement that converge towards the use, by the investigators, of a few instruments whose validity and reliability have been compared in different surroundings. In fact, the majority of investigations are based on ad-hoc questionnaires and a few of them present the questionnaire validation checking only the unidimensionality and -Cronbach. Nevertheless it seems to have a consensus in identifying 5 big constructs that compose the lean manufacturing (TQM, JIT, TPM, supply chain management and high-involvement. Our research has consisted of identifying and summarizing the models that have been published previously to add the items in constructs or sub-scales of constructs. Later we developed an integrating questionnaire, starting off of the items that appeared in previous investigations. Finally we realized the sub-scales and models validation through a confirmatory factorial analysis, using date of a sample of Spanish Sheltered Work Centre’s (N=128. Of all proposed models, the best an adjustment takes place with the first order model with 20 sub-scales. Our investigation contributes to an integrating vision of the published models and the lean manufacturing sub-scales validity and reliability verification raised by other investigators. Due to his confirming approach, it can serve as generalization of studies that had been realized in contexts with different samples to which we have used for the replication.

  6. Validation Effectiveness of Develop Maintainability Allocation on Aircraft Mechanical Components

    Full Text Available Maintainability Allocation is a process to identify the allowable maximum task time for each individual component. Consequently, this provides clear pictures to the designers to design and identify potential design improvement within allowable maintenance allocation time limits. During the design process elements such as missteps or misapplications most commonly occur. Here, the authors propose having the maximum target for each individual maintainability component. The main objective of this paper is to present the validation process of developed Maintainability Allocation to potentially eliminate previous problems. The process of validation begins with analysed all the data collected from Service Difficulty Reports (SDR for selected aircraft. This is to understand the problems from existing aircraft before a new design is proposed through the process of Maintainability Allocation prediction. The validation processes have discovered the importance of utilising historical information such as feedback information. The second area is looking at the element of quantifying the data collected from aircraft feedback information which contains various types of information that could be used for future improvement. Validation process shows that feedback information has helped to identify the critical and sensitive components that need more attention for further improvement. The study shows that the aircraft maintenance related feedback information systems analyses were very useful for deciding maintainability effectiveness; these include planning, organising maintenance and design improvement. There is no doubt that feedback information has the ability to contribute an important role in design activities. The results also show that maintainability is an important measure that can be used as a guideline for managing efforts made for the improvement of aircraft components.

  7. Development and validation of the response to sexual difficulties scale.

    Leading models of sexual dysfunction, such as those proposed by Masters and Johnson (1970), Barlow (1986), and Janssen, Everaerd, Spiering, and Janssen (2000), emphasize the role of anxiety and self-monitoring in the development and persistence of sexual difficulties. These models have considerable explanatory power, but focus on the intrapersonal factors that yield anxiety and self-monitoring. Accounting for the interpersonal context in which sexual activity occurs is also likely to be important. For example, anxiety and self-monitoring may arise from negative, yet accurate, predictions about how one's partner will respond to one's own sexual functioning difficulties. The current studies describe the development and validation of the Response to Sexual Difficulties Scale (RSDS), which was designed to assess how one expects one's partner to respond to one's own sexual difficulties (RSDS-Own Difficulties) and how one expects oneself to respond to one's partner's sexual difficulties (RSDS-Partner Difficulties). Study 1 established the initial reliability and construct validity of the RSDS-Own Difficulties in a sample of adults in committed relationships (N = 59). Study 2 further examined the construct and discriminant validity of the RSDS Own Difficulties and Partner Difficulties in a sample of heterosexual couples (N = 87). Results indicated that both measures had strong internal consistency and were not redundant with measures of mood or personality. Scores on the RSDS-Own Difficulties and Partner Difficulties were strongly associated, indicating that reports of one's own response to one's partner's difficulty matched the partner's assessment of the reaction. RSDS scores predicted sexual functioning, relationship satisfaction, sexual satisfaction, and sexual communication. The RSDS may, then, provide a useful means of assessing the role of interpersonal factors in the development and persistence of sexual difficulties.

    Acculturation is a multidimensional process involving changes in behaviour and beliefs. Questionnaires developed to measure acculturation are typically designed for specific ethnic populations and adult experiences. This study developed a questionnaire that measures acculturation among ethnically diverse populations of youth that can be included as a module in population surveys. Questionnaires measuring acculturation in youth were identified in the literature. The importance of items from the existing questionnaires was determined using a Delphi process and this informed the development of our questionnaire. The questionnaire was then pilot tested using a sample of 248 Canadians aged 18-25 via an online system. Participants identified as East and South East Asian (27.8%), South Asian (17.7%) and Black (13.7%). The majority were 1st (33.5%) or 2nd generation immigrants (52.0%). After redundant items were eliminated, exploratory factor analysis grouped items into domains, and, for each domain, internal consistency, and convergent validity with immigrant generation then age at immigration estimated. A subset of participants re-completed the questionnaire for reliability estimation. The literature review yielded 117 articles that used 13 questionnaires with a total of 440 questions. The Delphi process reduced these to 32 questions. Pilot testing occurred in 248 Canadians aged 18-25. Following item reduction, 16 questions in three domains remained: dominant culture, heritage language, and heritage culture. All had good internal consistency (Cronbach's alphas > .75). The mean dominant domain score increased with immigrant generation (1st generation: 3.69 (95% CI: 3.49-3.89), 2nd: 4.13 (4.00-4.26), 3rd: 4.40 (4.19-4.61)), and mean heritage language score was higher among those who immigrated after age 12 than before (p = .0001), indicative of convergent validity. This Bicultural Youth Acculturation Questionnaire has demonstrated validity. It can be incorporated into

    Full Text Available Abstract Background Low literacy and numeracy skills are common. Adequate numeracy skills are crucial in the management of diabetes. Diabetes patients use numeracy skills to interpret glucose meters, administer medications, follow dietary guidelines and other tasks. Existing literacy scales may not be adequate to assess numeracy skills. This paper describes the development and psychometric properties of the Diabetes Numeracy Test (DNT, the first scale to specifically measure numeracy skills used in diabetes. Methods The items of the DNT were developed by an expert panel and refined using cognitive response interviews with potential respondents. The final version of the DNT (43 items and other relevant measures were administered to a convenience sample of 398 patients with diabetes. Internal reliability was determined by the Kuder-Richardson coefficient (KR-20. An a priori hypothetical model was developed to determine construct validity. A shortened 15-item version, the DNT15, was created through split sample analysis. Results The DNT had excellent internal reliability (KR-20 = 0.95. The DNT was significantly correlated (p Conclusion The DNT is a reliable and valid measure of diabetes related numeracy skills. An equally adequate but more time-efficient version of the DNT, the DNT15, can be used for research and clinical purposes to evaluate diabetes related numeracy.

    Innovative curricula aim to improve content knowledge and the goal of helping students develop practices and skills of authentic scientist through active engagement learning. To students, these classroom practices often seem very different from their previous learning experiences in terms of behavioral expectations, learning attitude, and what learning means. We propose that productive participation in these learning environments require students to modify their identity as learners in addition to refining their science conceptual understanding. In order to measure changes in learning identity, we developed a 49-item survey to assess students' 1) expectations of student and teacher roles, 2) self efficacy towards skills supported in the Investigative Science Learning Environment (ISLE) and 3) attitudes towards social learning. Using principle components exploratory factor analysis, we have established two reliable factors with subscales that measure these student characteristics. This paper presents the survey development, validation and pilot study results.

    The present study aims to develop and validate a Chinese music quality rating test (MQRT). In Experiment 1, 22 music pieces were initially selected and paired as a 'familiar music piece' and 'unfamiliar music piece' based on familiarities amongst the general public in the categories of classical music (6), Chinese folk music (8), and pop music (8). Following the selection criteria, one pair of music pieces from each music category was selected and used for the MQRT in Experiment 2. In Experiment 2, the MQRT was validated using these music pieces in the categories 'Pleasantness', 'Naturalness', 'Fullness', 'Roughness', and 'Sharpness'. Seventy-two adult participants and 30 normal-hearing listeners were recruited in Experiments 1 and 2, respectively. Significant differences between the familiar and unfamiliar music pieces were found in respect of pleasantness rating for folk and pop music pieces as well as in sharpness rating for pop music pieces. The comparison of music category effect on MQRT found significant differences in pleasantness, fullness, and sharpness ratings. The Chinese MQRT developed in the present study is an effective tool for assessing music quality.

    Synthetic diagnostics are reproductions of experimental measurements obtained from simulation data, taking the same spatial averages (point, line, plane or volume) as in the experiment. This reduction of data facilitates meaningful direct quantitative comparisons which then allows for validation of simulation results. We demonstrate the development with data sets produced by highly spatially and temporally resolved NIMROD simulations with reference to the spheromak concept under development at UMBC. We present here results from a set of synthetic diagnostics that are scripted in Octave. Quantities such as magnetic field, temperature, and density are visually represented by color-coded graphs and movies to demonstrate how these quantities change over time. We discuss errors that enter into the computation of the quantities. Work performed under DARPA grant N66001-14-1-4044.

    This paper describes the dynamic model of a solar cooling plant that has been built for demonstration purposes using market-available technology and has been successfully operational since 2001. The plant uses hot water coming from a field of solar flat collectors which feed a single-effect absorption chiller of 35 kW nominal cooling capacity. The work includes model development based on first principles and model validation with a set of experiments carried out on the real plant. The simulation model has been done in a modular way, and can be adapted to other solar cooling-plants since the main modules (solar field, absorption machine, accumulators and auxiliary heater) can be easily replaced. This simulator is a powerful tool for solar cooling systems both during the design phase, when it can be used for component selection, and also for the development and testing of control strategies.

    Atenolol [4-(2-hydroxy-isopropylaminopropoxy)-phenylacetamide], is a cardioselective beta1-adrenergic receptor blocking agent prescribed for treatment of hypertension, angina pectoris and cardiac arrhythmias. However, most of these medicines are not formulated for easy or accurate administration to children. Atenolol is unstable in solutions and therefore the development of a liquid dosage form is a significant challenge. Studies showed that the degradation rate of atenolol is dependent on the temperature, indicating higher stability at 4 degrees C. Atenolol syrup is stable for 9 days, with acceptable apearance. A second order model adequately described atenolol decomposition when stored as syrup. A stability-indicating method was developed and validated in order to evaluate these studies.

    Objective. To describe the development, implementation and impact of a summative examination on student learning and programmatic curricular outcomes. Methods. The summative examination was developed using a systematic approach. Item reliability was evaluated using standard psychometric analyses. Content validity was assessed using necessity scoring as determined by subject matter experts. Results. Almost 700 items written by 37 faculty members were evaluated. Passing standards increased annually (45% in 2009 to 67% in 2014) as the result of targeting item difficulty and necessity scores. The percentage of items exhibiting discrimination above 0.1 increased to 100% over the four years. Necessity scores above 2.75 out of 4 increased from 65% to 100% of items over six years of examination administration. Conclusion. This examination successfully assessed student and curricular outcomes. Faculty member engagement observed in this process supports a culture of assessment. This type of examination could be beneficial to other programs.

    Full Text Available Th is research study aims at developing and validating CRM scale for Indian insurance sector. A robust scale development methodology is followed which ultimately results into Six - factor CRM scale comprising of claim payment security, product knowledge, per sonalization, transparency in product selling and service quality. The generalizability of the proposed scale can be tested by replicating the study in other nations. The proposed scale will serve as a strategic tool for effective and efficient pre and pos t CRM implementation outcomes. Apart from this it can also be used to identify the opportunities and bottleneck areas requiring attention. A fair amount of research studies have been done in Indian insurance sector but no such study is catered towards pro p osing a comprehensive measure of CRM effectiveness . In this direction this study aims to bridge this gap in the existing literature.

  20. Development and validation of a global dynamical wetlands extent scheme

    T. Stacke

    2012-01-01

    Full Text Available In this study we present the development of the dynamical wetland extent scheme (DWES and its validation against present day wetland observations. The DWES is a simple, global scale hydrological scheme that solves the water balance of wetlands and estimates their extent dynamically. The extent depends on the balance of water flows in the wetlands and the slope distribution within the grid cells. In contrast to most models, the DWES is not directly calibrated against wetland extent observations. Instead, wetland affected river discharge data are used to optimize global parameters of the model. The DWES is not a complete hydrological model by itself but implemented into the Max Planck Institute – Hydrology Model (MPI-HM. However, it can be transferred into other models as well.

    For present climate, the model validation reveals a good agreement between the occurrence of simulated and observed wetlands on the global scale. The best result is achieved for the northern hemisphere where not only the wetland distribution pattern but also their extent is simulated reasonably well by the DWES. However, the wetland fraction in the tropical parts of South America and Central Africa is strongly overestimated. The simulated extent dynamics correlate well with monthly inundation variations obtained from satellite for most locations. Also, the simulated river discharge is affected by wetlands resulting in a delay and mitigation of peak flows. Compared to simulations without wetlands, we find locally increased evaporation and decreased river flow into the oceans due to the implemented wetland processes.

    In summary, the validation analysis demonstrates the DWES' ability to simulate the global distribution of wetlands and their seasonal variations. Thus, the dynamical wetland extent scheme can provide hydrological boundary conditions for wetland related studies. In future applications, the DWES should be implemented into an earth system model

    In recent years, issues surrounding transgender have garnered media and legal attention, contributing to rapidly shifting views on gender in the U.S. Yet, there is a paucity of data-driven studies on the public's views of transgender identity. This study reports the development and validation of the Transgender Attitudes and Beliefs Scale (TABS). After constructing an initial 96-item pool from consulting experts and existing scales, Phase 1 of the study was launched, involving an exploratory factor analysis of 48 items. The initial factor analysis with 295 participants revealed three factors across 33 items-16 items on interpersonal comfort, 11 on sex/gender beliefs, and 6 on human value. The internal consistency of each factor was high-α = .97 for Factor 1, α = .95 for Factor 2, and α = .94 for Factor 3. A confirmatory factor analysis was conducted in the second phase with an independent sample consisting of 238 participants. The Attitudes Toward Transgender Individual Scale and the Genderism and Transphobia Scale were also included to test for convergent validity, and the Rosenberg Self-Esteem Scale and the short form of the Marlowe-Crowne Social Desirability Scale were utilized to test discriminant validity. Both of the data collection phases employed MTurk, a form of online sampling with increased diversity compared to college student samples and more generalizability to the general U.S. TABS represents an addition to the literature in its ability to capture a more nuanced conceptualization of transgender attitude not found in previous scales.

    Accurate treatment knowledge is required for patients to successfully manage complex medical conditions. Existing HIV knowledge scales focus on disease transmission and risk factors. This is the first study to develop and validate a scale to measure HIV treatment knowledge about complex treatment issues such as adherence, side-effects and drug resistance. A total of 346 participants were recruited into this cross-sectional study. Participants included HIV-positive patients (n=130), HIV-hepatitis C co-infected patients (n=22), hepatitis C patients, (n=78), community healthcare providers (n=35) and college students (n=81). Participants completed the proposed HIV Treatment Knowledge Scale and a validated measure of general knowledge about HIV transmission and risk factors. Two-week test-retest data were collected. Results demonstrated that the HIV Treatment Knowledge Scale was significantly correlated with general HIV knowledge across all samples. Among HIV-positive patients, the HIV Treatment Knowledge Scale was positively associated with time since HIV diagnosis. HAART-experienced patients had significantly higher treatment knowledge than HAART-naïve patients. HIV-positive patients scored significantly higher than hepatitis C patients and college students on HIV treatment knowledge. Test-retest reliability (r=0.83) and internal consistency (reliability coefficient=0.90) were both satisfactory. The HIV Treatment Knowledge Scale is a novel, easy-to-administer measure demonstrating high levels of validity and reliability. It has important applications as a clinical teaching tool with patients and healthcare workers and it could be used as an outcome indicator in HIV educational intervention studies.

  3. Development and Validation of the Behavioral Tendencies Questionnaire.

    Directory of Open Access Journals (Sweden)

    Nicholas T Van Dam

    Full Text Available At a fundamental level, taxonomy of behavior and behavioral tendencies can be described in terms of approach, avoid, or equivocate (i.e., neither approach nor avoid. While there are numerous theories of personality, temperament, and character, few seem to take advantage of parsimonious taxonomy. The present study sought to implement this taxonomy by creating a questionnaire based on a categorization of behavioral temperaments/tendencies first identified in Buddhist accounts over fifteen hundred years ago. Items were developed using historical and contemporary texts of the behavioral temperaments, described as "Greedy/Faithful", "Aversive/Discerning", and "Deluded/Speculative". To both maintain this categorical typology and benefit from the advantageous properties of forced-choice response format (e.g., reduction of response biases, binary pairwise preferences for items were modeled using Latent Class Analysis (LCA. One sample (n1 = 394 was used to estimate the item parameters, and the second sample (n2 = 504 was used to classify the participants using the established parameters and cross-validate the classification against multiple other measures. The cross-validated measure exhibited good nomothetic span (construct-consistent relationships with related measures that seemed to corroborate the ideas present in the original Buddhist source documents. The final 13-block questionnaire created from the best performing items (the Behavioral Tendencies Questionnaire or BTQ is a psychometrically valid questionnaire that is historically consistent, based in behavioral tendencies, and promises practical and clinical utility particularly in settings that teach and study meditation practices such as Mindfulness Based Stress Reduction (MBSR.

  4. Development and validation of the conceptions of scientific theories test

    Cotham, Joseph C.; Smith, Edward L.

    The purpose of this study was to develop a reliable and valid instrument for use with elementary and secondary teachers of science that would have the following characteristics: 1) sensitivity to alternative conceptions of particular philosophic aspects of scientific theories, and 2) applicability in inferring understanding of the tentative and revisionary conception of the nature of science. This conception, which has educational and social importance, may be a significant influence in the teaching of science as inquiry. Thus, concern with teachers' conceptions of the nature of science and their teaching served as justification for this study. The instrument, which was applied to samples of preservice elementary teachers, college philosophy of science students, and college chemistry students, consisted of items that were adapted to the contexts of particular scientific theories by prefacing them with a brief description of a theory and episodes drawn from its history. Items were written to discriminate between alternative conceptions of the following philosophic aspects of scientific theories: testing, generation, ontological implications, and choice. Evidence in support of the validity of the instrument constructs was obtained using two approaches: discrimination between contrasting groups and the multi-trait and multi-method matrix of Campbell and Fiske. Cronbach alpha reliability coefficients and standard errors of measurement were computed for the instrument and its subtests. Reliability data indicates that an adequate degree of accuracy may be attributed to instrument scores.

    Dysfunctional Attitude Scale is one of the most common instruments used to assess cognitive vulnerability. This study aimed to develop and validate a short form of Dysfunctional Attitude Scale appropriate for an Iranian clinical population. Participants were 160 psychiatric patients from medical centers affiliated with Isfahan Medical University, as well as 160 non-patients. Research instruments were clinical interviews based on the Diagnostic and Statistical Manual-IV-TR, Dysfunctional Attitude Scale and General Heath Questionnaire (GHQ-28). Data was analyzed using multicorrelation calculations and factor analysis. Based on the results of factor analysis and item-total correlation, 14 items were judged candidates for omission. Analysis of the 26-item Dysfunctional Attitude Scale (DAS-26) revealed a Cronbach's alpha of 0.92. Evidence for the concurrent criterion validity was obtained through calculating the correlation between the Dysfunctional Attitude Scale and psychiatric diagnosis (r = 0.55), GHQ -28 (r = 0.56) and somatization, anxiety, social dysfunction, and depression subscales (0.45,0.53,0.48, and 0.57, respectively). Factor analysis deemed a four-factor structure the best. The factors were labeled as success-perfectionism, need for approval, need for satisfying others, and vulnerability-performance evaluation. The results showed that the Iranian version of the Dysfunctional Attitude Scale (DAS-26) bears satisfactory psychometric properties suggesting that this cognitive instrument is appropriate for use in an Iranian cultural context.

    Main Objectives The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS). Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies). Methods In 11 independent studies (total N = 2,250), we demonstrate the SINS' psychometric properties. Results The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults), intrapersonal correlates (e.g., positive affect, depression), and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior). The SINS taps into the more fragile and less desirable components of narcissism. Significance The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures. PMID:25093508

    Full Text Available We report the development and validation of a scale to measure online shopping addiction. Inspired by previous theories and research on behavioral addiction, the Griffiths's widely accepted six-factor component model was referred to and an 18-item scale was constructed, with each component measured by three items. The results of exploratory factor analysis, based on Sample 1 (999 college students and confirmatory factor analysis, based on Sample 2 (854 college students showed the Griffiths's substantive six-factor structure underlay the online shopping addiction scale. Cronbach's alpha suggested that the resulting scale was highly reliable. Concurrent validity, based on Sample 3 (328 college students, was also satisfactory as indicated by correlations between the scale and measures of similar constructs. Finally, self-perceived online shopping addiction can be predicted to a relatively high degree. The present 18-item scale is a solid theory-based instrument to empirically measure online shopping addiction and can be used for understanding the phenomena among young adults.

    Full Text Available The spiritual well-being scale was developed as a way of assessing how well adults’ lives align with their values and their understanding of ultimate meaning in personal, social, environmental, and transcendental terms. The items on the scale were selected based on existing literature and essays addressing spirituality. The scale was then shown to 17 specialists in spirituality and edited in response to their comments to produce the last version of each item. The scale, composed of 49 items, was then administered to 865 adults (498 women, 57.6%; 367 men, 42.4%. Based on the results, the item set was then resolved to a 29-item scale, and Exploratory Factor Analysis revealed three significant dimensions of spirituality, which are transcendence, harmony with nature, and anomie. Construct validity and reliability were empirically ascertained and the goodness of fit was determined for the proposed model of spiritual well-being. (KMO: 951, when eigenvalue is 2; total item explanation variance: 58.337 %. The ensemble of the model’s coefficients are x²/sd = 4.11, RMESEA = .06, SRMR = .50, NFI = .90, CFI = .92. The results show that the Spiritual Well-Being Scale has the ability to measure adults’ spiritual well-being in a valid and reliable manner.

    Although measures of cultural identity, values, and behavior exist in the multicultural psychological literature, there is currently no measure that explicitly assesses ethnic minority individuals' positive and negative affect toward culture. Therefore, we developed 2 new measures called the Feelings About Culture Scale--Ethnic Culture and Feelings About Culture Scale--Mainstream American Culture and tested their psychometric properties. In 6 studies, we piloted the measures, conducted factor analyses to clarify their factor structure, and examined reliability and validity. The factor structure revealed 2 dimensions reflecting positive and negative affect for each measure. Results provided evidence for convergent, discriminant, criterion-related, and incremental validity as well as the reliability of the scales. The Feelings About Culture Scales are the first known measures to examine both positive and negative affect toward an individual's ethnic culture and mainstream American culture. The focus on affect captures dimensions of psychological experiences that differ from cognitive and behavioral constructs often used to measure cultural orientation. These measures can serve as a valuable contribution to both research and counseling by providing insight into the nuanced affective experiences ethnic minority individuals have toward culture.

    Full Text Available Abstract Background The use of routine hospital data for understanding patterns of adverse outcomes has been limited in the past by the fact that pre-existing and post-admission conditions have been indistinguishable. The use of a 'Present on Admission' (or POA indicator to distinguish pre-existing or co-morbid conditions from those arising during the episode of care has been advocated in the US for many years as a tool to support quality assurance activities and improve the accuracy of risk adjustment methodologies. The USA, Australia and Canada now all assign a flag to indicate the timing of onset of diagnoses. For quality improvement purposes, it is the 'not-POA' diagnoses (that is, those acquired in hospital that are of interest. Methods Our objective was to develop an algorithm for assessing the validity of assignment of 'not-POA' flags. We undertook expert review of the International Classification of Diseases, 10th Revision, Australian Modification (ICD-10-AM to identify conditions that could not be plausibly hospital-acquired. The resulting computer algorithm was tested against all diagnoses flagged as complications in the Victorian (Australia Admitted Episodes Dataset, 2005/06. Measures reported include rates of appropriate assignment of the new Australian 'Condition Onset' flag by ICD chapter, and patterns of invalid flagging. Results Of 18,418 diagnosis codes reviewed, 93.4% (n = 17,195 reflected agreement on status for flagging by at least 2 of 3 reviewers (including 64.4% unanimous agreement; Fleiss' Kappa: 0.61. In tests of the new algorithm, 96.14% of all hospital-acquired diagnosis codes flagged were found to be valid in the Victorian records analysed. A lower proportion of individual codes was judged to be acceptably flagged (76.2%, but this reflected a high proportion of codes used Conclusion An indicator variable about the timing of occurrence of diagnoses can greatly expand the use of routinely coded data for hospital quality

    Objectives Acculturation is a multidimensional process involving changes in behaviour and beliefs. Questionnaires developed to measure acculturation are typically designed for specific ethnic populations and adult experiences. This study developed a questionnaire that measures acculturation among ethnically diverse populations of youth that can be included as a module in population surveys. Methods Questionnaires measuring acculturation in youth were identified in the literature. The importance of items from the existing questionnaires was determined using a Delphi process and this informed the development of our questionnaire. The questionnaire was then pilot tested using a sample of 248 Canadians aged 18–25 via an online system. Participants identified as East and South East Asian (27.8%), South Asian (17.7%) and Black (13.7%). The majority were 1st (33.5%) or 2nd generation immigrants (52.0%). After redundant items were eliminated, exploratory factor analysis grouped items into domains, and, for each domain, internal consistency, and convergent validity with immigrant generation then age at immigration estimated. A subset of participants re-completed the questionnaire for reliability estimation. Results The literature review yielded 117 articles that used 13 questionnaires with a total of 440 questions. The Delphi process reduced these to 32 questions. Pilot testing occurred in 248 Canadians aged 18–25. Following item reduction, 16 questions in three domains remained: dominant culture, heritage language, and heritage culture. All had good internal consistency (Cronbach’s alphas > .75). The mean dominant domain score increased with immigrant generation (1st generation: 3.69 (95% CI: 3.49–3.89), 2nd: 4.13 (4.00–4.26), 3rd: 4.40 (4.19–4.61)), and mean heritage language score was higher among those who immigrated after age 12 than before (p = .0001), indicative of convergent validity. Conclusions This Bicultural Youth Acculturation Questionnaire has

    Full Text Available Abstract Background This paper describes the development of the Chinese Quality of Life Instrument (ChQOL which is a self-report health status instrument. Chinese Medicine relies very much on asking subjective feelings of patients in the process of diagnosis and monitoring of treatment. For thousands of years, Chinese Medicine practitioners have accumulated a good wealth of experiences in asking questions about health of their patients based on the concept of health in Chinese Medicine. These experiences were then transformed into questions for the ChQOL. It is believed that ChQOL can contribute to the existing Patient Report Outcome measures. This paper outlines the concept of health and disease in Traditional Chinese Medicine, the building of the conceptual framework of the ChQOL, the steps of drafting, selecting and validating the items, and the psychometric properties of the ChQOL. Methods The development of the ChQOL was based on the concept of health in Traditional Chinese Medicine with a theory driven approach. Based on the results of literature review, the research team developed an initial model of health which encompassed the concept of health in TCM. An expert panel was then invited to comment and give suggestions for improvement of the initial model. According to their suggestions, the model was refined and a set of initial items for the ChQOL was drafted. The refined model, together with the key domains, facets and initial items of the ChQOL were then mailed to a sample of about 100 Chinese medicine practitioners throughout Mainland China for their comments and advice. A revised set of items were developed for linguistic testing by a convenience sample consisting of both healthy people and people who attended Chinese Medicine treatment. After that, an item pool was developed for field-testing. Field test was conducted on a convenience sample of healthy and patient subjects to determine the construct validity and psychometric

    Despite the application of Self-Efficacy Theory (Bandura, 1977, 2000) to many areas of psychology, there is a lack of research on self-efficacy in the ability to testify in court. The present study fills this gap by incrementally developing the construct of Witness Self-Efficacy and establishing its psychometric properties. Study I features exploratory and confirmatory factor analyses yielding a two-factor Witness Self-Efficacy Scale (WSES). The two components are Poise and Communication Style. Study II uses a second data collection to show that both WSES domains possess convergent, divergent, and predictive validity relations consistent with those expected using an SET framework. Notably, WSES components predicted perceptions of witness credibility and sentencing outcomes above and beyond witness extraversion, general self-efficacy, and general self-confidence. Implications for SET and witness preparation training are discussed. Copyright © 2010 John Wiley & Sons, Ltd.

    In this article, we describe the development and validation of a short (10 item) but comprehensive self-report measure of childhood narcissism. The Childhood Narcissism Scale (CNS) is a 1-dimensional measure of stable individual differences in childhood narcissism with strong internal consistency reliability (Studies 1-4). The CNS is virtually unrelated to conventional measures of self-esteem but is positively related to self-appraised superiority, social evaluative concern and self-esteem contingency, agentic interpersonal goals, and emotional extremity (Study 5). Furthermore, the CNS is negatively related to empathic concern and positively related to aggression following ego threat (Study 6). These results suggest that childhood narcissism has similar psychological and interpersonal correlates as adult narcissism. The CNS provides researchers a convenient tool for measuring narcissism in children and young adolescents with strong preliminary psychometric characteristics.

    On-line monitoring and tracking of nuclear plant system and component degradation is being investigated as a method for improving the safety, reliability, and maintainability of aging nuclear power plants. Accurate prediction of the current degradation state of system components and structures is important for accurate estimates of their remaining useful life (RUL). The correct quantification and propagation of both the measurement uncertainty and model uncertainty is necessary for quantifying the uncertainty of the RUL prediction. This research project developed and validated methods to perform RUL estimation throughout the lifecycle of plant components. Prognostic methods should seamlessly operate from beginning of component life (BOL) to end of component life (EOL). We term this "Lifecycle Prognostics." When a component is put into use, the only information available may be past failure times of similar components used in similar conditions, and the predicted failure distribution can be estimated with reliability methods such as Weibull Analysis (Type I Prognostics). As the component operates, it begins to degrade and consume its available life. This life consumption may be a function of system stresses, and the failure distribution should be updated to account for the system operational stress levels (Type II Prognostics). When degradation becomes apparent, this information can be used to again improve the RUL estimate (Type III Prognostics). This research focused on developing prognostics algorithms for the three types of prognostics, developing uncertainty quantification methods for each of the algorithms, and, most importantly, developing a framework using Bayesian methods to transition between prognostic model types and update failure distribution estimates as new information becomes available. The developed methods were then validated on a range of accelerated degradation test beds. The ultimate goal of prognostics is to provide an accurate assessment for

    The USA National Phenology Network (USA-NPN; www.usanpn.org) serves science and society by promoting a broad understanding of plant and animal phenology and the relationships among phenological patterns and environmental change. The National Phenology Database (NPDb) maintained by USA-NPN contains almost 6 million in-situ observation records for plants and animals for the period 1954-2015. These data have been used in a number of science, conservation and natural resource management applications, including national assessments of historical and potential future trends in phenology and regional assessments of spatio-temporal variation in organismal activity. Customizable downloads of raw or summarized data, freely available from www.usanpn.org, are accompanied by metadata, data-use and data-attribution policies, published protocols, version/change control, documentation of QA/QC, and links to publications that use historical or contemporary data held in the NPDb. The National Coordinating Office of USA-NPN is developing a suite of standard data products (e.g., quality-controlled raw or summarized status data) and tools (e.g., a new visualization tool released in 2015) to facilitate use and application by a diverse set of data users. This presentation outlines a workflow for the development and validation of spatially gridded phenology products, drawing on recent work related to the Spring Indices now included in two national Indicator systems. In addition, we discuss how we engage observers to collect in-situ data to validate model predictions. Preliminary analyses indicate high fidelity between historical in-situ and modeled observations on a national scale, but with considerable variability at the regional scale. Regions with strong differences between expected and observed data are identified and will be the focus of in-situ data collection campaigns using USA-NPN's Nature's Notebook on-line user interface (www.nn.usanpn.org).

The rationale for the questionnaire is to bring together into one short instrument questions about two distinct domains – patients' reports of the outcomes of their care and how they experience care.Methods: The OEQ was developed from literature reviews, iterative drafting and discussion within the research group and cognitive testing with a sample of patients who had a hospital experience. Two validation studies were carried out with an eleven item OEQ. The goals of the studies were to examine response rates and to test specific hypotheses of how OEQ should relate to other variables normally collected in the two studies. In the first study, the OEQ was added to the follow-up questionnaires for patients (n=490 receiving surgery for hip or knee replacement or varicose vein procedures participating in the national Patient Reported Outcome Measures (PROMs program permitting the analysis of the OEQ against change scores for the measures obtained before and after surgery. In the second study the OEQ was included in a sample of patients (n=586 who had been selected to receive the National Health Service (NHS inpatient survey from three contrasting hospital trusts.Results: Results from study one provided consistent and substantial evidence of construct validity of OEQ particularly for those receiving hip or knee replacement. The OEQ sub-scales behaved differently and as predicted against other PROMs variables. Again hypotheses of how the two sub-scales regarding outcomes and experiences would relate to the existing domains of patient experience in the inpatient survey were broadly confirmed in study two

    To develop and perform reliability and validity assessments of the international Multidimensional Nursing Generations Questionnaire. There are three generations of nurses in the European workforce. There is little research on the characteristics of these generations and the ways in which to manage them professionally, and no instrument has yet been developed to measure these aspects specifically. With results from previous studies, 69 nursing generations-oriented items were created in English, translated into Italian and Finnish, and pretested to form the basis of an instrument that was tested between September and October 2014 on a sample of Finnish and Italian nurses (n = 1302) using principal component analysis and Cronbach's alpha. Fifty-four items and eight components (Cronbach's α range: 0.61-0.81) were identified in the instrument: (1) conflicts between generations; (2) patient safety view; (3) relationships between generations; (4) working as a multigenerational team; (5) orientation to change; (6) presenteeism and job propensity; (7) intention to leave, and (8) flexibility and availability. The instrument showed acceptable preliminary psychometric properties and satisfactory internal consistency. The Multidimensional Nursing Generations Questionnaire is a useful tool to measure the characteristics of different generations of nurses and to develop management strategies tailored to those generations. © 2017 John Wiley & Sons Ltd.

    The high cost of software production is driving development organizations to adopt more automated design and analysis methods such as rapid prototyping, computer-aided software engineering (CASE) tools, and high-level code generators. Even developers of safety-critical software system have adopted many of these new methods while striving to achieve high levels Of quality and reliability. While these new methods may enhance productivity and quality in many cases, we examine some of the risks involved in the use of new methods in safety-critical contexts. We examine a case study involving the use of a CASE tool that automatically generates code from high-level system designs. We show that while high-level testing on the system structure is highly desirable, significant risks exist in the automatically generated code and in re-validating releases of the generated code after subsequent design changes. We identify these risks and suggest process improvements that retain the advantages of rapid, automated development methods within the quality and reliability contexts of safety-critical projects.

    A railgun hydrogen pellet injector model is presented and its predictions are compared with the experimental data. High-speed hydrogenic ice injection is the dominant refueling method for magnetically confined plasmas used in controlled thermonuclear fusion research. As experimental devices approach the scale of power-producing fusion reactors, the fueling requirements become increasingly more difficult to meet since, due to the large size and the high electron densities and temperatures of the plasma, hypervelocity pellets of a substantial size will need to be injected into the plasma continuously and at high repetition rates. Advanced technologies, such as the railgun pellet injector, are being developed to address this demand. Despite the apparent potential of electromagnetic launchers to produce hypervelocity projectiles, physical effects that were neither anticipated nor well understood have made it difficult to realize this potential. Therefore, it is essential to understand not only the theory behind railgun operation, but the primary loss mechanisms, as well. Analytic tools have been used by many researchers to design and optimize railguns and analyze their performance. This has led to a greater understanding of railgun behavior and opened the door for further improvement. A railgun hydrogen pellet injector model has been developed. The model is based upon a pellet equation of motion that accounts for the dominant loss mechanisms, inertial and viscous drag. The model has been validated using railgun pellet injectors developed by the Fusion Technology Research Laboratory at the University of Illinois at Urbana-Champaign.

    Cisplatin is effective in the treatment of several cancers but is a known ototoxin resulting in shifts to hearing sensitivity in up to 50-60% of patients. Cisplatin-induced hearing shifts tend to occur first within an octave of a patient's high frequency hearing limit, termed the sensitive range for ototoxicity (SRO), and progress to lower frequencies. While it is currently not possible to know which patients will experience ototoxicity without testing their hearing directly, monitoring the SRO provides an early indication of damage. A tool to help forecast susceptibility to ototoxic-induced changes in the SRO in advance of each chemotherapy treatment visit may prove useful for ototoxicity monitoring efforts, patient counseling, and therapeutic planning. This project was designed to (1) establish pretreatment risk curves that quantify the probability that a new patient will suffer hearing loss within the SRO during treatment with cisplatin and (2) evaluate the accuracy of these predictions in an independent sample of Veterans receiving cisplatin for the treatment of cancer. Two study samples were used. The Developmental sample contained 23 subjects while the Validation sample consisted of 12 subjects. Risk curve predictions for SRO threshold shifts following cisplatin exposure were developed using a Developmental sample comprised of data from a total of 155 treatment visits obtained in 45 ears of 23 Veterans. Pure-tone thresholds were obtained within each subject's SRO at each treatment visit and compared with baseline measures. The risk of incurring an SRO shift was statistically modeled as a function of factors related to chemotherapy treatment (cisplatin dose, radiation treatment, doublet medication) and patient status (age, pre-exposure hearing, cancer location and stage). The model was reduced so that only statistically significant variables were included. Receiver-operating characteristic (ROC) curve analyses were then used to determine the accuracy of the

    Drop-out from 12-step groups is notoriously high, yet the field lacks strong models and scales for addressing this problem. We aim to determine whether the theory of planned behavior (TPB) can be applied to 12-step involvement, and to develop and validate a scale of 12-step readiness based on that theory: the Alcoholics Anonymous Intention Measure (AAIM). Data were from a longitudinal trial of a manual-guided 12-step facilitation intervention called Making AA Easier (MAAEZ) involving two treatment programs in California (N=508). Participants completed surveys at baseline, 7 weeks, 6 months, and 12 months. Surveys included the preliminary AAIM, a 12-step involvement measure, other readiness measures, and substance use outcomes. The final, 17-item AAIM measured Attitude (5-item alpha's=.75-.83), Subjective Norm (4-item alpha's=.56-.81), Perceived Control (5-item alpha's=.78-.85), and Intention (3-item alpha's=.80-.95) regarding attendance at 12-step groups. Components were correlated with each other and other readiness measures as expected, supporting the AAIM's validity. Scale components predicted 31% of the variance in Intention to attend 12-step groups at 6 months and 41% of the variance in 12-step involvement at 12 months. Social factors were among the strongest predictors of 12-step involvement. Results did not support the expectancy-value formulation of the TPB, as unweighted (vs. weighted) belief items performed optimally. Results generally support the TPB as a model of 12-step involvement and suggest specific targets for 12-step facilitation interventions within attitude, norm, and control components. Findings also support the AAIM as a tool for identifying drop-out risks and tailoring individual interventions.

    Full Text Available BACKGROUND: The objective of this study was to develop a questionnaire for caregivers to assess the eating behavior of Chinese preschoolers. METHODS: To assess children's eating behaviors, 152 items were derived from a broad review of the literature related to epidemiology surveys and the assessment of children's eating behaviors. All of these items were reviewed by 50 caregivers of preschoolers and 10 experienced pediatricians. Seventy-seven items were selected for use in a primary questionnaire. After conducting an exploratory factor analysis and a variability analysis on the data from 313 preschoolers used to evaluate this primary questionnaire, we deleted 39 of these 77 items. A Chinese Preschoolers' Eating Behavior Questionnaire (CPEBQ was finally established from the remaining 38 items. The structure of this questionnaire was explored by factor analysis, and its reliability, validity and discriminative ability were evaluated with data collected from caregivers of 603 preschoolers. RESULTS: The CPEBQ consisted of 7 dimensions and 38 items. The 7 dimensions were food fussiness, food responsiveness, eating habit, satiety responsiveness, exogenous eating, emotional eating and initiative eating. The Cronbach's α coefficient for the questionnaire was 0.92, and the test-retest reliability was 0.72. There were significant differences between the scores of normal-weight, overweight and obese preschoolers when it was referred to food fussiness, food responsiveness, eating habits, satiety responsiveness and emotional eating (p<0.05. Differences in caregiver's education levels also had significant effects on scores for food fussiness, eating habits and exogenous eating (p<0.05. CONCLUSIONS: The CPEBQ satisfies the conditions of reliability and validity, in accordance with psychometric demands. The questionnaire can be employed to evaluate the characteristics of Chinese preschoolers' eating behaviors; therefore, it can be used in child health care

    Alcohol consumption has been suggested to be associated with a dysregulation in habit formation and execution in dependent patients. Although there are established craving questionnaires assessing various components of craving, to our knowledge, no questionnaire exists to assess habitual and automated substance intake. In this study, we present and validate the "Craving Automated Scale for Alcohol" (CAS-A), a newly developed questionnaire assessing craving and other components of automated addictive behavior. Forty-three recently detoxified alcohol-dependent patients were examined in an inpatient setting using a cross-sectional design. The CAS-A, a self-report questionnaire, was applied. According to classical test theory, we conducted principal component analyses (PCAs) to identify the components of CAS-A, after which we validated it using established craving questionnaires. Thirty-two healthy participants served as a control group. Our first-order PCA identified a 5-factor solution. A second-order analysis then identified 2 general factors. These factors were partially associated with established craving measures and with the severity of dependence. Our findings suggest that CAS-A assesses additional components of addictive behavior compared to established measures. We interpret the 5 CAS-A factors as "only aware in hindsight," "no deliberate decision," "contrary to intention," "no perception," and "no control." We suggest the 2 general factors be interpreted as "unaware" and "nonvolitional." Our results indicate that the CAS-A indeed assesses some components of automated craving and automated drinking behavior in a more sophisticated way than established questionnaires. The CAS-A as a retrospective questionnaire can be considered to be a trait rather than a state measure. Copyright © 2015 by the Research Society on Alcoholism.

    Although the Manning equation is widely accepted as the empirical flow law for rough turbulent open-channel flow, using the equation in practical situations such as slope-area computations is fraught with uncertainty because of the difficulty in specifying the value of the reach resistance, Manning's n. Riggs (1976, J. Res. US Geol. Surv., 4: 285-291) found that n was correlated with water-surface slope, and proposed a multiple-regression equation that obviates the need for estimating n in slope-area estimates of discharge. Because his relation was developed from a relatively small sample ( N = 62), had potential flaws owing to multicollinearity, and was not thoroughly validated, we used an expanded data base ( N = 520) and objective methods to develop a new relation for the same purpose: Q = 1.564 A1.173R0.400S-0.0543log S where Q is discharge (m 3 s -1), A is cross-sectional area (m 2), R is hydraulic radius (m), and S is water-surface slope. We validated Rigg's model and our model using 100 measurements not included in model development and found that both give similar results. Riggs's model is somewhat better in terms of actual (m 3 s -1) error, but ours is better in terms of relative (log Q) error. We conclude that either Riggs's or our model can be used in place of Manning's equation in slope-area computations, but that our model is preferable because it has less bias, minimizes multicollinearity, and performs better when applied to discharge changes in individual reaches. We also found that our model performs better than those of Jarrett (1984, J. Hydraul. Eng., 110: 1519-1539) or Riggs in the range of applicability of Jarrett's equation (0.15 m ≤ R ≤ 2.13 m; 0.002 ≤ S ≤ 0.052). Both Riggs's and our models significantly overestimate Q in flows satisfying both the following conditions: Q < 3 m 3s -1 and Froude number less than 0.2. For other in-bank flows in relatively straight reaches, our model can be recommended for use in slope-area computations

    A satellite based surface visibility retrieval has been developed using Moderate Resolution Imaging Spectroradiometer (MODIS) measurements as a proxy for Advanced Baseline Imager (ABI) data from the next generation of Geostationary Operational Environmental Satellites (GOES-R). The retrieval uses a multiple linear regression approach to relate satellite aerosol optical depth, fog/low cloud probability and thickness retrievals, and meteorological variables from numerical weather prediction forecasts to National Weather Service Automated Surface Observing System (ASOS) surface visibility measurements. Validation using independent ASOS measurements shows that the GOES-R ABI surface visibility retrieval (V) has an overall success rate of 64.5% for classifying Clear (V ≥ 30 km), Moderate (10 km ≤ V skill during June through September, when Heidke skill scores are between 0.2 and 0.4. We demonstrate that the aerosol (clear sky) component of the GOES-R ABI visibility retrieval can be used to augment measurements from the United States Environmental Protection Agency (EPA) and National Park Service (NPS) Interagency Monitoring of Protected Visual Environments (IMPROVE) network, and provide useful information to the regional planning offices responsible for developing mitigation strategies required under the EPA's Regional Haze Rule, particularly during regional haze events associated with smoke from wildfires.

    Self-determination theory (SDT; Deci & Ryan, 2000) proposes that intrinsic, relative to extrinsic, goal content is a critical predictor of the quality of an individual's behavior and psychological well-being. Through three studies, we developed and psychometrically tested a measure of intrinsic and extrinsic goal content in the exercise context: the Goal Content for Exercise Questionnaire (GCEQ). In adults, exploratory (N = 354; Study 1) and confirmatory factor analyses (N = 312; Study 2) supported a 20-item solution consisting of 5 lower order factors (i.e., social affiliation, health management, skill development, image and social recognition) that could be subsumed within a 2-factor higher order structure (i.e., intrinsic and extrinsic). Evidence for external validity, temporal stability, gender invariance, and internal consistency of the GCEQ was found. An independent sample (N = 475; Study 3) provided further support for the lower order structure of the GCEQ and some support for the higher order structure. The GCEQ was supported as a measure of exercise-based goal content, which may help understand how intrinsic and extrinsic goals can motivate exercise behavior.

    Existing scales for experienced coercion have limitations. We developed and validated a short self-report form for experienced coercion for use across care settings, care phases, and care measures. In Stage 1, we developed an item pool, based on the literature, patient accounts, interviews, and expert feedback. Stages 2 and 3 consisted of 2 cross-sectional studies, with patients from acute and nonacute inpatient wards, outpatient care, and supported housing. In Stage 2, patients (N = 212) responded to the Coercion Ladder and the experienced coercion items from Stage 1. We selected 20 items for Stage 3 based on item performance in typically coercive versus voluntary care settings, each items' relation to the Coercion Ladder score, and with regard to the component structure from principal component analysis (PCA). In Stage 3, we collected and examined item responses and clinical and coercion data from a new sample of patients (N = 219). We selected 15 items based on factor loadings to form part of the final Experienced Coercion Scale (ECS). The internal consistency was high and score distribution approached the normal curve. ECS sum scores correlated strongly with scores on the Coercion Ladder. In a regression analysis, demographic variables, diagnosis, duration of treatment, and care setting did not predict ECS scores, while legal status and continuing involuntary medication significantly predicted scores. In this initial study, the ECS scores showed promising psychometric properties, suggesting it can be used across care settings and is suitable for research and service evaluation.

    2016-01-01

    This study describes the development of the Maladaptive Daydreaming Scale (MDS), a 14-item self-report instrument designed to gauge abnormal fantasizing. Our sample consisted of 447 English-speaking individuals from 45 different countries. A 3-correlated-factors model best presented the underlying dimensions Yearning, Kinesthesia and Impairment, capturing related rewarding experiences as well as psychological impairment of maladaptive daydreaming. MDS scores were associated with obsessive-compulsive behavior and thoughts, dissociative absorption, attention deficit, and high sense of presence during daydreaming, but less with psychotic symptoms. The MDS and its subscale demonstrated good validity, sound internal consistency and temporal stability and discriminated well between self-identified individuals with and without maladaptive daydreaming. Considering the instrument's high sensitivity and specificity levels, it seems an excellent measure for future investigation of MD that will, hopefully, shed light on the etiology and psycho-biological mechanisms involved in this mental condition, as well as on the development of effective MD treatment methods.

    Chronic interpersonal traumata systematically result in psychological impairments referred to as complex post-traumatic stress disorder (cPTSD or DESNOS). This diagnosis will be newly established in the ICD-11 system. However, there is need for diagnostic instruments to assess cPTSD. The aim was to develop a screening form to identify patients at risk for cPTSD. The Screening for complex PTSD (SkPTBS) tests a) experience of potential traumatic events, b) related influential features and risk factors, and c) symptoms of cPTSD. 325 patients (mean age 51.5±8.7 years; 62.1% female) filled out the screening instrument at the beginning of their inpatient psychotherapy. The primary criterion for testing SkPTBS validity was the diagnosis of complex PTSD at the end of the inpatient treatment. The proportion of patients with cPTSD was 8.9% (n=29). SkPTBS items were selective, and the scale showed very good reliability (α=0.91). Factor analysis revealed a one-dimensional structure. SkPTBS total values predicted having cPTSD diagnosis and were correlated with global symptom severity (SCL-90-R) and depressive symptoms (BDI-II). There is evidence for high clinical utility of SkPTBS. A revised version was developed. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available The development and construct validation process of the Paradoxical Personality Scale is presented in this paper. The concept assessed has been posed by Csikszentmihalyi (1996 and was described as related to creative individuals. Following his guidelines, 150 items were designed and judged by five experts, and later analysed from a facies standpoint. The resulting version was used in a sample of college students (n=473; 50.5% males, 49.5% females from 18 to 35 years ( = 21.82; DT= 3.14, to explore underlying dimensions. A 30item/6-factor solution was firstly isolated and after confirmed by a confirmatory factor analysis developed with 800 college students (44.4% males, 55.6% females, between18 and 35 years ( = 23.47; DT= 3.30. Both samples were selected from the population of college students from Buenos Aires, Argentina. Internal consistency and temporal stability of scores were also tested, obtaining adequate coefficients in both cases, in view of the composition of the dimensions underlying the construct analysed. Results show acceptable psychometric properties as well as shortness and simplicity for data gathering, which are discussed taking into account theoretical models and new research lines.

    KERENA is an advanced boiling water reactor, combining AREVA's and E.ON's expertise. A project was launched to customize the final basic design for this advanced nuclear power plant having a net power output of about 1, 250 MW, a net efficiency of about 37% and a design service life of 60 years. The development takes into account the technical and accumulated operating experience of the project partners. The plant safety concept is based on an optimized combination of a reduced number of proven active safety systems and passive safety systems, utilizing basic laws of physics, such as gravity, enabling them to function without electrical power supplies or activation by powered instrumentation and control systems. Control of a postulated core melt accident is assured with considerable safety margins thanks to passive flooding of the containment for in-vessel melt retention. All passive safety systems are validated in an experimental test program at AREVA, using 1:1 scale test facilities (INKA test facility Karlstein). The KERENA boiling water reactor is compliant with international nuclear codes and standards, and is also designed to withstand the effects of an aircraft crash involving a military aircraft or a large passenger airline. The safety level of the KERENA reactor has been able to be significantly increased compared to existing BWR plants. The advantages of the new safety concept are: -) Reduced susceptibility of safety systems to failures; -) Larger safety margins; -) Good plant behavior in the event of accidents due to the fact that conditions change at a slower rate; -) Grace periods of several days after an accident before operator intervention is required; -) Significantly reduced impact of operator error on reactor safety; -) No need for large-scale emergency response actions such as temporary evacuation or relocation of the neighboring population following a core melt accident.

    Full Text Available Purpose: Global competition and ever changing customers demand have made manufacturing organizations to rapidly adjust to complexities, uncertainties, and changes. Therefore, flexibility in manufacturing resources is necessary to respond cost effectively and rapidly to changing production needs and requirements.  Ability of manufacturing resources to dynamically reallocate from one stage of a production process to another in response to shifting bottlenecks is recognized as resource flexibility. This paper aims to develop and validate resource flexibility measures for manufacturing industry that could be used by managers/ practitioners in assessing and improving the status of resource flexibility for the optimum utilization of resources. Design/methodology/approach: The study involves survey carried out in Indian manufacturing industry using a questionnaire to assess the status of various aspects of resource flexibility and their relationships. A questionnaire was specially designed covering various parameters of resource flexibility. Its reliability was checked by finding the value of Cronback alpha (0.8417. Relative weightage of various measures was found out by using Analytical Hierarchy Process (AHP. Pearson’s coefficient of correlation analysis was carried out to find out relationships between various parameters. Findings: From detailed review of literature on resource flexibility, 17 measures of resource flexibility and 47 variables were identified. The questionnaire included questions on all these measures and parameters. ‘Ability of machines to perform diverse set of operations’ and ability of workers to work on different machines’ emerged to be important measures with contributing weightage of 20.19% and 17.58% respectively.  All the measures were found to be significantly correlated with overall resource flexibility except ‘training of workers’, as shown by Pearson’s coefficient of correlation. This indicates that

    This study was designed to investigate the convergent validity of individual clinical task interviews as presented by Piaget and Inhelder paired with three widely used group tests of cognitive development. These tests are designed to assess the acquisition of cognitive abilities. The three group test raw scores paired with summed raw scores on four concrete-formal task interviews yielded the following Pearson product-moment correlations: Reasoning Test (Ankney and Joyce), 0.43; Logical Reasoning Test (Burney), 0.61; Classroom Test of Formal Operations (Lawson), 0.37. The raw data was then ranked into cognitive level groups and presented on contingency tables. The following contingency coefficients were determined: Logical Reasoning Test, 0.52; Logical Reasoning Test (adjusted), 0.61; Classroom Test of Formal Operations, 0.50. This study reflects that the Reasoning Test tends to indicate lower cognitive levels of subjects when paired with summed scores on the clinical task interviews, whereas the Logical Reasoning Test and the Classroom Test of Formal Operations tend to indicate higher cognitive levels of subjects when paired with summed scores on the clinical task interviews. In each case the correlations do not appear to be sufficiently strong to warrant selection or categorization of an individual student based on his/her test performance.

    Contemporary research into science education has generally been conducted from the perspective of 'conceptual change' in learning. This study sought to extend previous work by recognizing that human rationality can be influenced by the emotions generated by the learning environment and specific actions related to learning. Methods used in educational psychology were adopted to investigate the emotional experience of science students as affected by gender, teaching methods, feedback, and learning tasks. A multidisciplinary research approach combining brain activation measurement with multivariate psychological data theory was employed in the development of a questionnaire intended to reveal the academic emotions of university students in three situations: attending science class, learning scientific subjects, and problem solving. The reliability and validity of the scale was evaluated using exploratory and confirmatory factor analyses. Results revealed differences between the genders in positive-activating and positive-deactivating academic emotions in all three situations; however, these differences manifested primarily during preparation for Science tests. In addition, the emotions experienced by male students were more intense than those of female students. Finally, the negative-deactivating emotions associated with participation in Science tests were more intense than those experienced by simply studying science. This study provides a valuable tool with which to evaluate the emotional response of students to a range of educational situations.

    Full Text Available An examination of the psychometric properties of the Lateral Violence in Nursing Survey (LVNS, an instrument previously developed to measure the perceived incidence and severity of lateral violence (LV in the nursing workplace, was carried out. Conceptual clustering and principal components analysis were used with survey responses from 663 registered nurses and ancillary nursing staff in a southeastern tertiary care medical center. Where appropriate, Cronbach’s alpha (α evaluated internal consistency. The prevalence/severity of lateral violence items constitute two distinct subscales (LV by self and others with Cronbach’s alpha of 0.74 and 0.86, respectively. The items asking about potential causes of LV are unidimensional and internally consistent (alpha = 0.77 but there is no conceptually coherent theme underlying the various causes. Respondents rating a potential LV cause as “major” scored higher on both prevalence/severity subscales than those rating it a “minor” cause or not a cause. Subsets of items on the LVNS are internally reliable, supporting construct validity. Revisions of the original LVNS instrument will improve its use in future work.

    Morphing fears (also called transformation obsessions) involve concerns that a person may become contaminated by and acquire undesirable characteristics of others. These symptoms are found in patients with obsessive-compulsive disorder (OCD) and are thought to be related to mental contamination. Given the high levels of distress and interference morphing fears can cause, a reliable and valid assessment measure is needed. This article describes the development and evaluation of the Morphing Fear Questionnaire (MFQ), a 13-item measure designed to assess for the presence and severity of morphing fears. A sample of 900 participants took part in the research. Of these, 140 reported having a current diagnosis of OCD (SR-OCD) and 760 reported never having had OCD (N-OCD; of whom 24 reported a diagnosis of an anxiety disorder and 23 reported a diagnosis of depression). Factor structure, reliability and construct and criterion-related validity were investigated. Exploratory and confirmatory factor analyses supported a one-factor structure replicable across the N-OCD and SR-OCD group. The MFQ was found to have high internal consistency and good temporal stability and showed significantly greater associations with convergent measures (assessing obsessive-compulsive symptoms, mental contamination, thought-action fusion and magical thinking) than with divergent measures (assessing depression and anxiety). Moreover, the MFQ successfully discriminated between the SR-OCD sample and the N-OCD group, anxiety disorder sample and depression sample. These findings suggest that the MFQ has sound psychometric properties and that it can be used to assess morphing fear. Clinical implications are discussed. Copyright © 2015 John Wiley & Sons, Ltd. Little remains known about morphing fears, but it is an important area of investigation due to symptoms being highly distressing and often debilitating Because morphing fears commonly present as obscure symptoms, they may not be recognized as a

    Bayldon, John Michael

    2007-12-01

    In composite manufacturing, Vacuum Assisted Resin Transfer Molding (VARTM) is becoming increasingly important as a cost effective manufacturing method of structural composites. In this process the dry preform (reinforcement) is placed on a rigid tool and covered by a flexible film to form an airtight vacuum bag. Liquid resin is drawn under vacuum through the preform inside the vacuum bag. Modeling of this process relies on a good understanding of closely coupled phenomena. The resin flow depends on the preform permeability, which in turn depends on the local fluid pressure and the preform compaction behavior. VARTM models for predicting the flow rate in this process do exist, however, they are not able to properly predict the flow for all classes of reinforcement material. In this thesis, the continuity equation used in VARTM models is reexamined and a modified form proposed. In addition, the compaction behavior of the preform in both saturated and dry states is studied in detail and new models are proposed for the compaction behavior. To assess the validity of the proposed models, the shadow moire method was adapted and used to perform full field measurement of the preform thickness during infusion, in addition to the usual measurements of flow front position. A new method was developed and evaluated for the analysis of the moire data related to the VARTM process, however, the method has wider applicability to other full field thickness measurements. The use of this measurement method demonstrated that although the new compaction models work well in the characterization tests, they do not properly describe all the preform features required for modeling the process. In particular the effect of varying saturation on the preform's behavior requires additional study. The flow models developed did, however, improve the prediction of the flow rate for the more compliant preform material tested, and the experimental techniques have shown where additional test methods

    Currently the majority of space-based assets are located inside the Earth's magnetosphere where they must endure the effects of the near-Earth space environment, i.e. space weather, which is driven by the supersonic flow of plasma from the Sun. Space weather refers to the day-to-day changes in the temperature, magnetic field and other parameters of the near-Earth space, similarly to ordinary weather which refers to changes in the atmosphere above ground level. Space weather can also cause adverse effects on the ground, for example, by inducing large direct currents in power transmission systems. The performance of computers has been growing exponentially for many decades and as a result the importance of numerical modeling in science has also increased rapidly. Numerical modeling is especially important in space plasma physics because there are no in-situ observations of space plasmas outside of the heliosphere and it is not feasible to study all aspects of space plasmas in a terrestrial laboratory. With the increasing number of computational cores in supercomputers, the parallel performance of numerical models on distributed memory hardware is also becoming crucial. This thesis consists of an introduction, four peer reviewed articles and describes the process of developing numerical space environment/weather models and the use of such models to study the near-Earth space. A complete model development chain is presented starting from initial planning and design to distributed memory parallelization and optimization, and finally testing, verification and validation of numerical models. A grid library that provides good parallel scalability on distributed memory hardware and several novel features, the distributed cartesian cell-refinable grid (DCCRG), is designed and developed. DCCRG is presently used in two numerical space weather models being developed at the Finnish Meteorological Institute. The first global magnetospheric test particle simulation based on the

    Terrorism creates lingering anxiety about future attacks. In prior terror research, the conceptualization and measurement of coping behaviors were constrained by the use of existing coping scales that index reactions to daily hassles and demands. The authors created and validated the Coping with Terror Scale to fill the measurement gap. The authors emphasized content validity, leveraging the knowledge of terror experts and groups of Israelis. A multistep approach involved construct definition and item generation, trimming and refining the measure, exploring the factor structure underlying item responses, and garnering evidence for reliability and validity. The final scale comprised six factors that were generally consistent with the authors' original construct specifications. Scores on items linked to these factors demonstrate good reliability and validity. Future studies using the Coping with Terror Scale with other populations facing terrorist threats are needed to test its ability to predict resilience, functional impairment, and psychological distress.

    The advanced 3D-coal combustion code AIOLOS for quasi-stationary turbulent reacting flows is based on a conservative finite-volume procedure. Equations for the conservation of mass, momentum and scalar quantities are solved. In order to deal with pressurized combustion chambers which are usually of cylindrical shape, a first task in the frame of the project consisted in the extension of the code towards cylindrical co-ordinates, since the basic version of AIOLOS was only suitable for cartesian grids. Furthermore, the domain decomposition method was extended to the new co-ordinate system. Its advantage consists in the possibility to introduce refined sub-grids, providing a better resolution of regions where high gradients occur (e.g. high velocity and temperature gradients near the burners). The accuracy of the code was proven by means of a small-scale test case. The results obtained with AIOLOS were compared with the predictions of the commercial CFD-code FLOW3D and validated against the velocity and temperature distributions measured at the test facility. The work during the second period focused mainly on the extension of the reaction model, as well as on the modelling of the optical properties of the flue gas. A modified submodel for char burnout was developed, considering the influence of pressure on diffusion mechanisms and on the chemical reaction at the char particle. The goal during the third project period was to improve the numerical description of turbulence effects and of the radiative heat transfer, in order to obtain an adequate modelling of the complex processes in pressurized coal combustion furnaces. Therefore, a differential Reynolds stress turbulence model (RSM) and a Discrete-Ordinates radiation model were implemented, respectively. 13 refs., 13 figs., 1 tab.

    Food-guide pyramids help translate nutrient goals into a visual representation of suggested food intake on a population level. No such guidance system has ever been specifically designed for athletes. Therefore, the authors developed a Food Pyramid for Swiss Athletes that illustrates the number of servings per food group needed in relation to the training volume of an athlete. As a first step, an average energy expenditure of 0.1 kcal . kg(-1) . min(-1) for exercise was defined, which then was translated into servings of different food groups per hour of exercise per day. Variable serving sizes were defined for athletes' different body-mass categories. The pyramid was validated by designing 168 daily meal plans according to the recommendations of the pyramid for male and female athletes of different body-mass categories and training volumes of up to 4 hr/d. The energy intake of the meal plans met the calculated reference energy requirement by 97% +/- 9%. The carbohydrate and protein intakes were linearly graded from 4.6 +/- 0.6-8.5 +/- 0.8 g . kg(-1) . d(-1) and 1.6 +/- 0.2-1.9 +/- 0.2 g . kg(-1) . d(-1), respectively, for training volumes of 1-4 hr of exercise per day. The average micronutrient intake depended particularly on the dietary energy intake level but was well above the dietary reference intake values for most micronutrients. No tolerable upper intake level was exceeded for any micronutrient. Therefore, this Food Pyramid for Swiss Athletes may be used as a new tool in sports nutrition education (e.g., teaching and counseling).

    Trait affect scales have been a mainstay of the assessment literature for more than 50 years. These scales have demonstrated impressive construct validity, including substantial relations with personality, satisfaction, and psychopathology. However, the accumulating evidence has exposed several limitations, including (a) problems associated with retrospective biases, (b) lower temporal stability because of enhanced susceptibility to transient error, and (c) reduced self-other agreement. These limitations motivated the creation of the Temperament and Affectivity Inventory (TAI), which uses a traditional personality format (i.e., full sentences rather than single words or short phrases). The 12 TAI scales were created based on factor analyses in two samples and validated in four additional samples. The scales are internally consistent, highly stable over time, and show strong convergent, discriminant, and incremental validity in relation to self-report and interview-based measures of personality and psychopathology. Thus, the TAI provides a promising new approach to assessing trait affectivity.

  13. Development and Validation of Sterility Systems for Trees

    2007-03-30

    The overall goal of this project was to develop and validate sterility systems in poplar with the ultimate goal of fulfilling the basic requirements for commercial use. For this, sterility must be complete and stable over multiple growing seasons, cause no detrimental effects on vegetative growth, and successful transformation events must be identifiable via molecular tests when trees are still juvenile. Because of the inherent difficulties in achieving and demonstrating complete sterility in trees, our approach was to study alternate sterility systems in Arabidopsis and/or early-flowering tree systems. The public benefit from this work is the capacity for containment of genes or exotic forms of trees so they can be of benefit for industry for production of wood, energy, and renewable products, while having minimal impact on wild populations of trees. We tested three methods for engineering sterility: dominant negative mutant (DNM) proteins, floral tissue ablation, and RNA interference (RNAi) to suppress the expression of several floral regulatory genes. The ultimate goal of this work was to produce a number of transgenic poplars that could be outplanted to enable future assessments of the effectiveness of these transgenic sterility methods. Our attempts to produce ablation constructs that did not interfere with tree health were partially successful. Using the poplar LEAFY gene promoter and the barnase/barstar system, we were able to regenerate plants that grew well in the greenhouse, but they showed poor health in the field. Four of seven DNM genes tested were considered promising enough, based on results in Arabidopsis, to produce transgenic poplars. Single, double, and triple RNAi genes were produced and transformed into poplar. Over all, we produced 1,964 PCR-confirmed transgenic events with 19 different kinds of sterility genes and several kinds of control genes. We propagated 5,640, 6,820, and 7,055 trees for each of three test poplar genotypes, and field

    2012-01-01

    Paruresis, characterized by the difficulty or inability to urinate in a variety of social contexts, is a scientifically under-studied phenomenon. One reason for this state of affairs is the paucity of reliable and valid measures for assessing this problem. The present article attempted to address this limitation by investigating the psychometric properties and validity of a new measure of paruresis: the Shy Bladder Scale (SBS). In two undergraduate samples, the SBS demonstrated excellent internal consistency and a stable factor structure assessing difficulty urinating in public, impairment and distress, and paruresis-related fear of negative evaluation. Undergraduate students evidenced very low levels of paruresis-related concerns. In contrast, SBS scores were markedly elevated among individuals recruited from an online support network who appeared to meet diagnostic criteria for paruresis-specific social phobia. Our findings highlight the SBS's potential utility as a measure of paruresis in clinical and research contexts.

    Llatas, C; Osmani, M

    2016-10-01

    Reduction in construction waste is a pressing need in many countries. The design of building elements is considered a pivotal process to achieve waste reduction at source, which enables an informed prediction of their wastage reduction levels. However the lack of quantitative methods linking design strategies to waste reduction hinders designing out waste practice in building projects. Therefore, this paper addresses this knowledge gap through the design and validation of a Building Design Waste Reduction Strategies (Waste ReSt) model that aims to investigate the relationships between design variables and their impact on onsite waste reduction. The Waste ReSt model was validated in a real-world case study involving 20 residential buildings in Spain. The validation process comprises three stages. Firstly, design waste causes were analyzed. Secondly, design strategies were applied leading to several alternative low waste building elements. Finally, their potential source reduction levels were quantified and discussed within the context of the literature. The Waste ReSt model could serve as an instrumental tool to simulate designing out strategies in building projects. The knowledge provided by the model could help project stakeholders to better understand the correlation between the design process and waste sources and subsequently implement design practices for low-waste buildings.

    Full Text Available Consumer-Company Identification is a relatively new issue in the marketing academia. Bhattacharya and Sen(2003 explored the Social Identity theory and established Consumer-Company Identification as the primary psychological substrate for deep relationships between the organization and its customers. In the present study a new instrument was constructed and validated that permits the empirical verification of the phenomenon described by Bhattacharya and Sen (2003. The scale validated in the present study is the first to embrace the idiosyncrasies of the identification between consumers and organizations. The process was conducted through 3 independent data collections. The first one was collected using literature search and in-depth interviews with 12 undergraduate students and bachelors from different professional fields. The second data base was obtained from a survey of 226 undergraduate students from 3 universities in 2 big Brazilian cities. This data base was used for purification purposes using Explanatory Factorial Analysis. Finally, the Structural Equation Modeling technique was applied to analyze a third data base composed of 387 observations collected from the same 3 universities of the second study. The results confirm the content, convergent and discriminant validity of the new scale proposed.

    2015-01-30

    Motivation deficits are common in several disorders including schizophrenia, and are an important factor in both functioning and treatment adherence. Self-Determination Theory (SDT), a leading macro-theory of motivation, has contributed a number of insights into how motivation is impaired in schizophrenia. Nonetheless, self-report measures of motivation appropriate for people with severe mental illness (including those that emphasize SDT) are generally lacking in the literature. To fill this gap, we adapted and abbreviated the well-validated General Causality Orientation Scale for use with people with schizophrenia and with other severe mental disorders (GCOS-clinical populations; GCOS-CP). In Study 1, we tested the similarity of our measure to the existing GCOS (using a college sample) and then validated this new measure in a schizophrenia and healthy control sample (Study 2). Results from Study 1 (N=360) indicated that the GCOS-CP was psychometrically similar to the original GCOS and provided good convergent and discriminant validity. In Study 2, the GCOS-CP was given to individuals with (N=44) and without schizophrenia (N=42). In line with both laboratory-based and observer-based research, people with schizophrenia showed lower motivational autonomy and higher impersonal/amotivated orientations. Additional applications of the GCOS-CP are discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The purpose of this project was to prepare and operate a fast pyrolysis process development unit (PDU) that can validate experimental data generated at the bench scale. In order to do this, a biomass preparation system, a modular fast pyrolysis fluidized bed reactor, modular gas clean-up systems, and modular bio-oil recovery systems were designed and constructed. Instrumentation for centralized data collection and process control were integrated. The bio-oil analysis laboratory was upgraded with the addition of analytical equipment needed to measure C, H, O, N, S, P, K, and Cl. To provide a consistent material for processing through the fluidized bed fast pyrolysis reactor, the existing biomass preparation capabilities of the ISU facility needed to be upgraded. A stationary grinder was installed to reduce biomass from bale form to 5-10 cm lengths. A 25 kg/hr rotary kiln drier was installed. It has the ability to lower moisture content to the desired level of less than 20% wt. An existing forage chopper was upgraded with new screens. It is used to reduce biomass to the desired particle size of 2-25 mm fiber length. To complete the material handling between these pieces of equipment, a bucket elevator and two belt conveyors must be installed. The bucket elevator has been installed. The conveyors are being procured using other funding sources. Fast pyrolysis bio-oil, char and non-condensable gases were produced from an 8 kg/hr fluidized bed reactor. The bio-oil was collected in a fractionating bio-oil collection system that produced multiple fractions of bio-oil. This bio-oil was fractionated through two separate, but equally important, mechanisms within the collection system. The aerosols and vapors were selectively collected by utilizing laminar flow conditions to prevent aerosol collection and electrostatic precipitators to collect the aerosols. The vapors were successfully collected through a selective condensation process. The combination of these two mechanisms

    Leonard, Carrie A; Staples, Jaime; Williams, Robert J

    2015-09-01

    Existing research has demonstrated that poker is a game predominated by skill. Little is known about the specific characteristics of good poker players however, likely due in part to the lack of a readily available measure of poker skill. In the absence of an available and easily administered poker skill measure, laboratory studies of poker player attributes have used questionable methodologies to assess skill including peer- and self-report. The aim of the current research was to create a valid, reliable, and easily administered measure of poker playing skill. A sample of 100 University of Lethbridge undergraduate students and Lethbridge community members completed the newly created Poker Skills Measure (PSM) and an objective measure of poker playing performance (playing virtual poker). External validity of the measure was demonstrated via significant associations—expected and detected—between the PSM and the objective playing measure. Specifically, significant positive associations were found between PSM scores and hands won, pre- and post flop aggression, and a significant negative relationship was detected between PSM scores and number of hands played. Within the current sample, acceptable internal consistency (Cronbach's α = .82) and very good test re-test reliability (r = .78) was achieved with the 35 item PSM. Future directions are discussed.

    2010-01-01

    Full Text Available This study employed qualitative construct mapping and factor analysis to construct a scale to measure attitudes toward dementia. Five family caregivers, five professionals, and five college students participated in structured interviews. Qualitative analysis of the interviews led to a 46-item scale, which was reduced to 20 items following principal axis factoring with two different samples: college students (=302 and certified nursing assistant students (=145. Confirmatory factor analysis was then conducted with another sample of college students (=157. The final scale, titled the Dementia Attitudes Scale (DAS, essentially had a two-factor structure; the factors were labeled “dementia knowledge” and “social comfort.” Total-scale Cronbach's alphas ranged 0.83–0.85. Evidence for convergent validity was promising, as the DAS correlated significantly with scales that measured ageism and attitudes toward disabilities (range of correlations = 0.44–0.55; mean correlation =0.50. These findings demonstrate the reliability and validity of the DAS, supporting its use as a research tool.

    2010-03-01

    The validation parameters for pharmaceutical analyses were examined for the accelerator mass spectrometry measurement of (14)C/C ratio, independent of chemical separation procedures. The isotope ratio measurement was specific (owing to the (14)C label), stable across samples storage conditions for at least 1 year, linear over four orders of magnitude with an analytical range from 0.1 Modern to at least 2000 Modern (instrument specific). Furthermore, accuracy was excellent (between 1 and 3%), while precision expressed as coefficient of variation was between 1 and 6% determined primarily by radiocarbon content and the time spent analyzing a sample. Sensitivity, expressed as LOD and LLOQ was 1 and 10 attomoles of (14)C, respectively (which can be expressed as compound equivalents) and for a typical small molecule labeled at 10% incorporated with (14)C corresponds to 30 fg equivalents. Accelerator mass spectrometry provides a sensitive, accurate and precise method of measuring drug compounds in biological matrices.

    Webb, Monica C; Chaney, J Don; Chen, W William; Dodd, Virginia J; Huang, I-Chan; Sanders, Sadie

    2015-02-01

    Through the use of multi-modal methods, the purpose of this study was to develop and assess measurement properties of an instrument evaluating specific sexual behaviors of college students and the role alcohol intoxication plays in one's intention to participate in these behaviors. A modified version of N. Krause's instrument development process was applied to create a behavior-specific instrument assessing oral, vaginal, and anal sex behaviors. The process included a review by expert scholars in relevant fields, cognitive interviews with the target population using screen-capture program Camtasia, piloting to assess measurement scales, and a formal investigation. The applied instrument development process employed screen capture software and web-based surveying in a cost-effective format suitable for mixed-method measurement development. The development and application of the instrument provides a clearer understanding of the relationship between alcohol use and sexual activity and aids in the development of effective public health interventions and policies.

  2. Development and validation of a realistic head model for EEG

    Science.gov (United States)

    Bangera, Nitin Bhalchandra

    The utility of extracranial electrical or magnetic field recordings (EEG or MEG) is greatly enhanced if the generators of the bioelectromagnetic fields can be determined accurately from the measured fields. This procedure, known as the 'inverse method,' depends critically on calculations of the projection from generators in the brain to the EEG and MEG sensors. Improving and validating this calculation, known as the 'forward solution,' is the focus of this dissertation. The improvements involve more accurate modeling of the structures of the brain and thus understanding how current flows within the brain as a result of addition of structures in the forward model. Validation compares calculations using different forward models to the experimental results obtained by stimulating with implanted dipole electrodes. The human brain tissue displays inhomogeneity in electrical conductivity and also displays anisotropy, notably in the skull and brain white matter. In this dissertation, a realistic head model has been implemented using the finite element method to calculate the effects of inhomogeneity and anisotropy in the human brain. Accurate segmentation of the brain tissue type is implemented using a semi-automatic method to segment multimodal imaging data from multi-spectral MRI scans (different flip angles) in conjunction with the regular T1-weighted scans and computed x-ray tomography images. The electrical conductivity in the anisotropic white matter tissue is quantified from diffusion tensor MRI. The finite element model is constructed using AMIRA, a commercial segmentation and visualization tool and solved using ABAQUS, a commercial finite element solver. The model is validated using experimental data collected from intracranial stimulation in medically intractable epileptic patients. Depth electrodes are implanted in medically intractable epileptic patients in order to direct surgical therapy when the foci cannot be localized with the scalp EEG. These patients

    2016-01-01

    We quantified medical signs and symptoms to construct the Physical Symptom Score (PSS) for use in research to assess somatic disease burden in mucopolysaccharidoses (MPS) to track disease and monitor treatments. We examined scoring reliability, its concurrent validity with other measures, and relationship to age in MPS type I. Fifty-four patients with MPS I (36 with Hurler syndrome treated with hematopoietic cell transplant and 18 with attenuated MPS I treated with enzyme replacement therapy), ages 5 to 18 years, were seen longitudinally over 5 years. The summation of frequency and severity of signs of specific organ involvement, surgeries, and hydrocephalus drawn from medical histories comprise the PSS. We examined relationship to age and to daily living skills (DLS) from the Vineland Adaptive Behavior Scale and physical quality of life from the Child Health Questionnaire (CHQ) for each group. The PSS was associated with age in both groups, indicating increase in disease burden over time. The PSS was significantly negatively associated with DLS (r = -0.48) and CHQ (r = -0.55) in the attenuated MPS I but not in the Hurler group. The association of somatic disease burden with physical quality of life and ability to carry out daily living skills suggests that the PSS will be useful in the measurement of disease and treatment effects in the attenuated MPS I group. Earlier treatment with transplant and differing parental expectations are possible explanations for its lack of association with other outcomes necessitating an adaptation for Hurler syndrome in the future.

    Lee, Younju; Lee, Mihyoung

    2014-04-01

    The purpose of this study was to develop an instrument to assess bullying of nurses, and test the validity and reliability of the instrument. The initial thirty items of WPBN-TI were identified through a review of the literature on types bullying related to nursing and in-depth interviews with 14 nurses who experienced bullying at work. Sixteen items were developed through 2 content validity tests by 9 experts and 10 nurses. The final WPBN-TI instrument was evaluated by 458 nurses from five general hospitals in the Incheon metropolitan area. SPSS 18.0 program was used to assess the instrument based on internal consistency reliability, construct validity, and criterion validity. WPBN-TI consisted of 16 items with three distinct factors (verbal and nonverbal bullying, work-related bullying, and external threats), which explained 60.3% of the total variance. The convergent validity and determinant validity for WPBN-TI were 100.0%, 89.7%, respectively. Known-groups validity of WPBN-TI was proven through the mean difference between subjective perception of bullying. The satisfied criterion validity for WPBN-TI was more than .70. The reliability of WPBN-TI was Cronbach's α of .91. WPBN-TI with high validity and reliability is suitable to determine types of bullying in nursing workplace.

    The development of the Chinese Positive Youth Development Scale (CPYDS) is outlined in this paper. The CPYDS assesses 15 aspects of positive youth development, including bonding, resilience, social competence, emotional competence, cognitive competence, moral competence, behavioral competence, self-determination, self-efficacy, spirituality, positive view of the future, positive self-identity, prosocial involvement, prosocial norms, and recognition for positive behavior. Based on a Well Adjustment Group (N=162) and a Poor Adjustment Group (N=264), the present findings showed that the CPYDS and its subscales possess acceptable internal consistency. Except the Self-Efficacy Subscale, the CPYDS total and subscale scores were able to discriminate the two groups. While the CPYDS total and subscale scores were positively related to thriving, wellness assessment and life satisfaction measures, they were negatively related to substance abuse, delinquency, and behavioral intention to engage in problem behavior. The present findings provide support for the reliability and validity of the CPYDS to assess positive youth development in the Chinese culture.

  6. The Pain-Related Cognitive Processes Questionnaire: Development and Validation.

    Day, Melissa A; Ward, L Charles; Thorn, Beverly E; Lang, Cathryne P; Newton-John, Toby R O; Ehde, Dawn M; Jensen, Mark P

    2017-03-06

     Cognitive processes may be characterized as how individuals think, whereas cognitive content constitutes what individuals think. Both cognitive processes and cognitive content are theorized to play important roles in chronic pain adjustment, and treatments have been developed to target both. However, the evaluation of treatments that target cognitive processes is limited because extant measures do not satisfactorily separate cognitive process from cognitive content. The current study aimed to develop a self-report inventory of potentially adaptive and presumed maladaptive attentional processes that may occur when someone is experiencing pain.  Scales were derived from a large item pool by successively applying confirmatory factor analysis to item data from two undergraduate samples (N = 393 and 233).  Items, which were generated to avoid confounding of cognitive content with cognitive processes, represented nine constructs: Suppression, Distraction, Enhancement, Dissociation, Reappraisal, Absorption, Rumination, Nonjudgment, and Acceptance. The resulting nine scales formed the Pain-Related Cognitive Process Questionnaire (PCPQ), and scale correlations produced four conceptually distinct composite scales: Pain Diversion, Pain Distancing, Pain Focus, and Pain Openness. Internal consistency reliabilities of the nine scales were adequate (α ≥ 0.70) to good, and the four composite scales had α values of 0.79 or higher. Correlations with pain-related criterion variables were generally consistent with putative constructs.  The developed PCPQ scales offer a comprehensive assessment of important cognitive processes specific to pain. Overall, the findings suggest that the PCPQ scales may prove useful for evaluating the role of pain-related cognitive processes in studies of chronic pain.

The sensitivity and specificity was compared to previous assays utilized for detection (PGMY and MY09/11 PCR with dot blot hybridization using cloned HPV-32 L1, the closely related HPV-42 L1 as well as clinical samples (oral swabs and fluids from 89 HIV-positive subjects. Results The HPV-32 specific PCR assay showed improved sensitivity to 5 copies of HPV-32 as compared to the PGMY PCR, MY09/11 PCR and dot blot which had a limit of detection of approximately 3,000 copies. Using the HPV-32 dot blot hybridization assay as the gold standard, the HPV-32 specific PCR assay has a sensitivity of 95.8% and 88.9% by sample and subject, respectively, and specificity was 87.8% and 58.8% by sample and subject, respectively. The low sensitivity is due to the HPV-32 specific PCR assays ability to detect more HPV-32 positive samples and may be the new gold standard. Conclusion Due to the ease, sensitivity, and specificity the HPV-32 specific PCR assay is superior to previous assays and is ideal for detection of HPV-32 in large cohorts. This assay provides an excellent tool to study the natural history of HPV-32 infection and the development of oral warts.

    The current project sought to develop the Mexican Intercultural Competence Scale (MICS), which assesses group-specific skills and attributes that facilitate effective cultural interactions, among adults of Mexican descent. Study 1 involved an Exploratory Factor Analysis (N = 184) that identified five factors including Ambition/Perseverance, Networking, the Traditional Latino Culture, Family Relationships, and Communication. In Study 2, a Confirmatory Factor Analysis provided evidence for the 5-factor model for adults of Mexican origin living in the Midwest (N = 341) region of the U.S. The general findings are discussed in terms of a competence-based formulation of cultural adaptation and include theoretical and clinical implications.

    This report describes the initial results of a study being conducted as part of the Urban Search Planning Tool project. The study is comparing the Urban Scene Simulator (USS), a one-dimensional (1D) radiation transport model developed at LLNL, with the three-dimensional (3D) radiation transport model from ORNL using the MCNP, SCALE/ORIGEN and SCALE/MAVRIC simulation codes. In this study, we have analyzed the differences between the two approaches at every step, from source term representation, to estimating flux and detector count rates at a fixed distance from a simple surface (slab), and at points throughout more complex 3D scenes.

    System-identification methods compose a mathematical model, or series of models, from measurements of inputs and outputs of dynamic systems. The extracted models allow the characterization of the response of the overall aircraft or component subsystem behavior, such as actuators and on-board signal processing algorithms. This paper discusses the use of frequency-domain system-identification methods for the development and integration of aircraft flight-control systems. The extraction and analysis of models of varying complexity from nonparametric frequency-responses to transfer-functions and high-order state-space representations is illustrated using the Comprehensive Identification from FrEquency Responses (CIFER) system-identification facility. Results are presented for test data of numerous flight and simulation programs at the Ames Research Center including rotorcraft, fixed-wing aircraft, advanced short takeoff and vertical landing (ASTOVL), vertical/short takeoff and landing (V/STOL), tiltrotor aircraft, and rotor experiments in the wind tunnel. Excellent system characterization and dynamic response prediction is achieved for this wide class of systems. Examples illustrate the role of system-identification technology in providing an integrated flow of dynamic response data around the entire life-cycle of aircraft development from initial specifications, through simulation and bench testing, and into flight-test optimization.

    Microgravity exposure affects visual acuity in a subset of astronauts and mechanisms may include structural changes in the posterior globe and orbit. Particularly, posterior globe flattening has been implicated in the eyes of several astronauts. This phenomenon is known to affect some terrestrial patient populations and has been shown to be associated with intracranial hypertension. It is commonly assessed by magnetic resonance imaging (MRI), computed tomography (CT) or B-mode Ultrasound (US), without consistent objective criteria. NASA uses a semiquantitative scale of 0-3 as part of eye/orbit MRI and US analysis for occupational monitoring purposes. The goal of this study was ot initiate development of an objective quantification methodology to monitor small changes in posterior globe flattening.

    Transgender-inclusive behaviors are actions and communication supporting transgender individuals. Examples include using language not reinforcing the gender binary, asking for and using correct pronouns, creation of spaces that welcome members of the transgender community, and acknowledging cisgender (non-transgender) privilege. A survey was developed measuring this behavior in individuals to examine the impact of transgender-inclusive behavior and the potential effect of interventions on promoting inclusive behavior. Data were collected utilizing an online survey (N = 1,051). The sample was split in half to run two sets of cases in a principal components analysis. Analysis of the full sample showed Cronbach's alpha to be .93 (n = 918). Findings suggest that the Transgender Inclusive Behavior Scale (TIBS) may be a useful instrument for identifying behaviors related to being inclusive of transgender individuals, groups, and communities. It may also be used to measure behavior change before and after transgender-specific educational and behavioral interventions.

    Batterers' resistance to traditional intervention programs has been well documented. Within a Transtheoretical Model of Change (stage of change) framework, a measure of processes of resistance was developed and administered to 346 adult male domestic violence offenders in treatment. The study yielded a 38-item measure that assesses eight dimensions of resistance: (a) System Blaming, (b) Problems with Partner, (c) Problems with Alliance, (d) Social Justification, (e) Hopelessness, (f) Isolation, (g) Psychological Reactance, and (h) Passive Reactance. The relationship between resistance and stage of change, time in treatment, and partner aggression are reported. Results suggest that we look beyond the most common forms of resistance (e.g., denial and victim-blaming) to identify and address other forms of resistance that may be more internally based and difficult to detect. The processes of resistance measure provides a tool for measuring those types of resistance.

    Full Text Available We describe the development of a healthy aging survey for older Thai adults. Domains of physical, psychological, social and spiritual health were identified as relevant based on focus groups of older Thai adults and a synthesis of Western and Thai literature on aging. A 4-phase approach was employed. First, for each domain, we selected measures that had been used in Thailand and/or in other countries, and adapted them for older Thai adults. Second, 2 forward translations from English to Thai and 1 back translation were conducted. Third, the survey was pretested by using a general debriefing pretest and cognitive interviewing. Last, the final scales were selected based on factor analysis and psychometric properties assessed in a sample of 350 older Thai community-dwelling adults. Factor analysis explained 61.8 - 74.5 % of the variance within each domain. The final survey consisted of 72 items with 16 scales. Most scales achieved good reliability; 13 scales had a Cronbach’s alpha greater than 0.70 (range 0.48 and 0.93. A 2-week test-retest reliability showed acceptable Pearson correlations. The first-generation survey demonstrates good psychometric properties and provides the basis for measuring healthy aging in the older Thai adult population. The survey may also be applicable to other cultures.

    The impact of biotechnologies on peoples' everyday lives continuously increases. Measuring young peoples' attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of substantial number of instruments which focused on measuring student attitudes toward biotechnology, a majority of them were not rigorously validated. This study deals with the development and validation of an attitude questionnaire toward biotechnology. Detailed information on development and validation process of the instrument is provided. Data gathered from 326 university students provided evidence for the validity and reliability of the new instrument which consists of 28 attitude items on a five point likert type scale. It is believed that the instrument will serve as a valuable tool for both instructors and researchers in science education to assess students' biotechnology attitudes.

    Santa Ana winds, common to southern California during the fall through spring, are a type of katabatic wind that originates from a direction generally ranging from 360°/0° to 100° and is usually accompanied by very low humidity. Since fuel conditions tend to be driest from late September through the middle of November, Santa Ana winds occurring during this period have the greatest potential to produce large, devastating fires when an ignition occurs. Such catastrophic fires occurred in 1993, 2003, 2007, and 2008. Because of the destructive nature of these fires, there has been a growing desire to categorize Santa Ana wind events in much the same way that tropical cyclones have been categorized. The Santa Ana Wildfire Threat index (SAWT) is an attempt to categorize such events with respect to fire activity, based on surface wind velocity, dew point depression, and forecasted fuel conditions. The index, a USDA Forest Service product, was developed by the Forest Service in collaboration with San Diego Gas and Electric Utility (SDG&E), the Department of Atmospheric and Oceanic Sciences at UCLA, The Desert Research Institute (DRI), and Vertum Partners. The methodology behind the SAWT index, along with the index itself will be presented in detail. Also, there will be a discussion on the construction of a 30-year climatology of the index, which includes various meteorological and fuel parameters. We will demonstrate the usefulness of the index as another decision support tool for fire agencies and first responders, and how it could assist the general public and private industry in the preparation of critical Santa Ana wind events.

    Full Text Available A size-segregated aerosol dynamics model UHMA (University of Helsinki Multicomponent Aerosol model was developed for studies of multicomponent tropospheric aerosol particles. The model includes major aerosol microphysical processes in the atmosphere with a focus on new particle formation and growth; thus it incorporates particle coagulation and multicomponent condensation, applying a revised treatment of condensation flux onto free molecular regime particles and the activation of nanosized clusters by organic vapours (Nano-Köhler theory, as well as recent parameterizations for binary H2SO4-H2O and ternary H2SO4-NH3-H2O homogeneous nucleation and dry deposition. The representation of particle size distribution can be chosen from three sectional methods: the hybrid method, the moving center method, and the retracking method in which moving sections are retracked to a fixed grid after a certain time interval. All these methods can treat particle emissions and atmospheric transport consistently, and are therefore suitable for use in large scale atmospheric models. In a test simulation against an accurate high resolution solution, all the methods showed reasonable treatment of new particle formation with 20 size sections although the hybrid and the retracking methods suffered from artificial widening of the distribution. The moving center approach, on the other hand, showed extra dents in the particle size distribution and failed to predict the onset of detectable particle formation. In a separate test simulation of an observed nucleation event, the model captured the key qualitative behaviour of the system well. Furthermore, its prediction of the organic volume fraction in newly formed particles, suggesting values as high as 0.5 for 3–4 nm particles and approximately 0.8 for 10 nm particles, agrees with recent indirect composition measurements.

    2005-12-15

    Dental pain, estimated to affect 12-40% of community-dwelling adults, is a symptom of a wide range of clinical conditions. A population screening instrument is needed to study their prevalence. This project aimed to develop a questionnaire for classifying a sample of dental pain patients into three groups of common dental pain conditions, i.e. Group 1 (Acute periapical periodontitis and Irreversible pulpitis), Group 2 (Reversible pulpitis and Dentine hypersensitivity) and Group 3 (Pericoronitis). Initial items were generated through a literature review, individual unstructured patient interviews and consultation with experts. Items generated were administered to a sample of dental pain patients for self-completion. Responses were subjected to a series of factor and discriminant analyses to identify questions capable of differentiating the sample into three groups, originally categorized by clinical diagnosis, with high classification rates. The selected items were administered to a further sample of dental pain patients to test for its sensitivity and specificity in classifying the sample into three groups against the gold standard of clinical diagnosis. The final 16-item Dental Pain Questionnaire (DePaQ) was capable of correctly classifying 89.7% of dental pain cases initially categorized by clinical diagnoses. The sensitivity of the questionnaire was 0.80-Group z1, 0.85-Group 2 and 0.59-Group 3. Specificity was 0.83-Group A1, 0.89-Group A2 and 0.90-Group 3. The DePaQ, which can easily be administered by non-clinical personnel, may be used to collect epidemiological data on common dental pain conditions, assess dental needs for a specified population, and triage of patients seeking treatment for dental pain.

    Aggressive resuscitation can decrease sepsis mortality, but its success depends on early detection of sepsis. The purpose of this study was to develop and verify an Automated Sepsis Risk Assessment System (Auto-SepRAS), which would automatically assess the sepsis risk of inpatients by applying data mining techniques to electronic health records (EHR) data and provide daily updates. The seven predictors included in the Auto-SepRAS after initial analysis were admission via the emergency department, which had the highest odds ratio; diastolic blood pressure; length of stay; respiratory rate; heart rate; and age. Auto-SepRAS classifies inpatients into three risk levels (high, moderate, and low) based on the predictive values from the sepsis risk-scoring algorithm. The sepsis risk for each patient is presented on the nursing screen of the EHR. The AutoSepRAS was implemented retrospectively in several stages using EHR data and its cut-off scores adjusted. Overall discrimination power was moderate (AUC>.80). The Auto-SepRAS should be verified or updated continuously or intermittently to maintain high predictive performance, but it does not require invasive tests or data input by nurses that would require additional time. Nurses are able to provide patients with nursing care appropriate to their risk levels by using the sepsis risk information provided by the Auto-SepRAS. In particular, with early detection of changes related to sepsis, nurses should be able to help in providing rapid initial resuscitation of high-risk patients. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Introduction Facilitation of child development is usually emphasized in the form of early intervention classes and practical demonstrations. However, non-adherence to home program for such interventions has been reported due to various reasons. Aim To develop and validate an educational leaflet as a supplement guide for caregivers to promote better development of their child during 4-6 months of age. Materials and Methods An in-depth literature review and focus group discussion with the experts was conducted to formulate the content of leaflet. Initial framework consisted of introduction, main text with pictorial representation and instructions about facilitation of various milestones, do’s–don’ts and disclaimer. Validation was done through a questionnaire consisting of 9 questions pertaining to completeness, understandability, legibility, clarity and utility of educational material for caregivers and a section for comments. Leaflet with enclosed questionnaire was distributed to 14 validators (2 neonatologists, 4 paediatricians and 8 physiotherapists), along with a covering letter stating the purpose and relevance of this educational material, and the importance of their participation in validation process. Scoring was done on 5 point Likert scale for each item in the material. Results Responses from the 14 evaluators were collected and analysed. Item level content validity index (I-CVI) was calculated for individual items which ranged from 0.73 – 1. Scale level Content Validity Index (S-CVI) was calculated for complete nine items and it was found to be 0.91. Validators expressed their views to include a column on normal milestones across 4-6 months of age and also to highlight the significance of performing each activity mentioned in the leaflet. These suggestions were incorporated in consensus with the subject experts and the final draft was made. Conclusion Educational leaflet for caregivers of 4-6 months preterm infants has been developed and validated

    The Cognitive Style Questionnaire (CSQ) measures the cognitive vulnerability factor featured in the hopelessness theory of depression. The CSQ has been used in over 30 published studies since its inception, yet detailed information about the psychometric and validity properties of this instrument has yet to be published. In this article, we describe the development of the CSQ and review reliability and validity evidence. Findings to date using college samples, indicate that the CSQ is a reliable measure of cognitive vulnerability with a high degree of construct validity.

    Representatives from eleven Organization for Economic Co-operation and Development member countries participated in an exercise to validate computer calculations to evaluate the criticality safety for several fissile material transport and handling situations. A procedure evolved from this work which has been shown to demonstrate whether a given computation method produces ''valid'' results. This procedure is expected to provide a basis for acceptance of computational results on an international basis by regulatory authorities through the comparison of methods used by the various countries. This work will also provide the framework for validating computational methods for other applications such as heat transfer and neutron/gamma shielding.

    Atheoretical measure purification may lead to construct deficient measures. The purpose of this paper is to provide a theoretically driven procedure for the development and empirical validation of symmetric component measures of multidimensional constructs. Particular emphasis is placed on establishing a formalized three-step procedure for achieving a posteriori content validity. Then the procedure is applied to development and empirical validation of two symmetrical component measures of market orientation, customer orientation and competitor orientation. Analysis suggests that average variance extracted is particularly critical to reliability in the respecification of multi-indicator measures. In relation to this, the results also identify possible deficiencies in using Cronbach alpha for establishing reliable and valid measures.

    The series of related studies reported here describe the development and validation of the Organizational Stressor Indicator for Sport Performers (OSI-SP). In study 1, an expert and usability panel examined the content validity and applicability of an initial item pool. The resultant 96 items were analyzed with exploratory factor analyses in Study 2, with the factorial structure comprising 5 factors (viz., goals and development, logistics and operations, team and culture, coaching, selection) and 33 items. Using confirmatory factor analyses, Studies 3 and 4 found support for the 5-factor structure. Study 4 also provided evidence for the OSI-SP's concurrent validity and invariance across different groups. The OSI-SP is proposed as a valid and reliable measure of the organizational stressors encountered by sport performers.

    Few instruments provide reliable and valid data on child well-being and contextual assets during middle childhood, using children as informants. The authors developed a population-level, self-report measure of school-aged children's well-being and assets-the Middle Years Development Instrument (MDI)-and examined its reliability and validity. The MDI was designed to assess child well-being inside and outside of school on five dimensions: (1) Social and emotional development, (2) Connectedness to peers and to adults at school, at home, and in the neighborhood, (3) School experiences, (4) Physical health and well-being, and (5) Constructive use of time after school. This paper describes the theoretical framework, selection of items and scales for the survey, and four studies that were conducted to revise the MDI and examine its psychometric properties. The findings indicate a theoretically predicted factor structure, high internal consistency, and document the convergent and discriminant validity of the MDI scales. The discussion delineates a plan for future validation studies that address further validity questions, such as predictive validity, measurement invariance, and fairness/bias, and provides a brief outlook of how the MDI may be used by practitioners, educators, and decision makers in schools and communities to motivate and inform action in support children's well-being.

    This article describes the development and validation of the Core Competencies Scale (CCS) using Bok's (2006) competency framework for undergraduate education. The framework included: communication, critical thinking, character development, citizenship, diversity, global understanding, widening of interest, and career and vocational development. The sample comprised 70 college and university students. Results of analysis using Rasch rating scale modelling showed that there was strong empirical evidence on the validity of the measures in contents, structure, interpretation, generalizability, and response options of the CCS scale. The implication of having developed Rasch-based valid and dependable measures in this study for gauging the value added of college and university education to their students is that the feedback generated from CCS will enable evidence-based decision and policy making to be implemented and strategized. Further, program effectiveness can be measured and thus accountability on the achievement of the program objectives.

    Increasingly, commercial immunoassay kits are used to support drug discovery and development. Longitudinally consistent kit performance is crucial, but the degree to which kits and reagents are characterized by manufacturers is not standardized, nor are the approaches by users to adapt them and evaluate their performance through validation prior to use. These factors can negatively impact data quality. This paper offers a systematic approach to assessment, method adaptation and validation of commercial immunoassay kits for quantification of biomarkers in drug development, expanding upon previous publications and guidance. These recommendations aim to standardize and harmonize user practices, contributing to reliable biomarker data from commercial immunoassays, thus, enabling properly informed decisions during drug development.

    This work presents the design, development, testing and validation of a Photonic Virtual Laboratory, highlighting the study of LEDs. The study was conducted from a conceptual, experimental and didactic standpoint, using e-learning and m-learning platforms. Specifically, teaching tools that help ensure that our students perform significant learning have been developed. It has been brought together the scientific aspect, such as the study of LEDs, with techniques of generation and transfer of knowledge through the selection, hierarchization and structuring of information using concept maps. For the validation of the didactic materials developed, it has been used procedures with various assessment tools for the collection and processing of data, applied in the context of an experimental design. Additionally, it was performed a statistical analysis to determine the validity of the materials developed. The assessment has been designed to validate the contributions of the new materials developed over the traditional method of teaching, and to quantify the learning achieved by students, in order to draw conclusions that serve as a reference for its application in the teaching and learning processes, and comprehensively validate the work carried out.

    The aim of this study was to develop and psychometrically validate a new instrument that comprehensively measures video game satisfaction based on key factors. Playtesting is often conducted in the video game industry to help game developers build better games by providing insight into the players' attitudes and preferences. However, quality feedback is difficult to obtain from playtesting sessions without a quality gaming assessment tool. There is a need for a psychometrically validated and comprehensive gaming scale that is appropriate for playtesting and game evaluation purposes. The process of developing and validating this new scale followed current best practices of scale development and validation. As a result, a mixed-method design that consisted of item pool generation, expert review, questionnaire pilot study, exploratory factor analysis (N = 629), and confirmatory factor analysis (N = 729) was implemented. A new instrument measuring video game satisfaction, called the Game User Experience Satisfaction Scale (GUESS), with nine subscales emerged. The GUESS was demonstrated to have content validity, internal consistency, and convergent and discriminant validity. The GUESS was developed and validated based on the assessments of over 450 unique video game titles across many popular genres. Thus, it can be applied across many types of video games in the industry both as a way to assess what aspects of a game contribute to user satisfaction and as a tool to aid in debriefing users on their gaming experience. The GUESS can be administered to evaluate user satisfaction of different types of video games by a variety of users. © 2016, Human Factors and Ergonomics Society.

    Full Text Available This study is a report on the design, development, and validation of a model within the main tenets of critical pedagogy (CP with a hope to implement in education in general and applied linguistics in particular. To develop a transformative L2 materials preparation (TLMP model, the researchers drew on Crawford’s (1978 principles of CP as a springboard. These principles provide the theoretical framework of the ELT program in general, but they need to be adapted to the specific features of L2 materials development. To this end, Nation and Macalister’s (2010 model of materials development were utilized to base different aspects of materials preparation. The newly developed model has driven 22 principles which was validated through a stepwise process. It was administered among 110 participants in 15 cities of Iran. Exploratory and confirmatory factor analyses were performed. The results indicated a high level of internal consistency and satisfactory construct validity. The TLMP model could be conducive for language policy makers, ELT professionals, materials and curriculum developers.

    Full Text Available ABSTRACT OBJECTIVE To validate a Spanish version of the Test of Gross Motor Development (TGMD-2 for the Chilean population. METHODS Descriptive, transversal, non-experimental validity and reliability study. Four translators, three experts and 92 Chilean children, from five to 10 years, students from a primary school in Santiago, Chile, have participated. The Committee of Experts has carried out translation, back-translation and revision processes to determine the translinguistic equivalence and content validity of the test, using the content validity index in 2013. In addition, a pilot implementation was achieved to determine test reliability in Spanish, by using the intraclass correlation coefficient and Bland-Altman method. We evaluated whether the results presented significant differences by replacing the bat with a racket, using T-test. RESULTS We obtained a content validity index higher than 0.80 for language clarity and relevance of the TGMD-2 for children. There were significant differences in the object control subtest when comparing the results with bat and racket. The intraclass correlation coefficient for reliability inter-rater, intra-rater and test-retest reliability was greater than 0.80 in all cases. CONCLUSIONS The TGMD-2 has appropriate content validity to be applied in the Chilean population. The reliability of this test is within the appropriate parameters and its use could be recommended in this population after the establishment of normative data, setting a further precedent for the validation in other Latin American countries.

    Full Text Available Traditional classroom situation where students are taught predominantly of lecture-discussion method put the classroom in a mathophobic atmosphere. Oftentimes, students exposed to this classroom atmosphere lead to math anxiety and eventually hate the subject and the teacher. Addressing this, varied interactive strategies to create an atmosphere of discourse has been developed and promoted. The use of instructional games has been viewed as one strategy that promotes active learning inside the classroom. Instructional games support constructivist learning and social learning. This study is aimed at developing, validating and evaluating card pairing games for specific topics in Math 8. The Research and Development model ( R& D was used. The card pairing games was validated by subject experts and experts in developing games. In evaluating the card pairing games, the Quasi-Experimental Pretest-Posttest design was used. There are six card pairing games developed for specific topics in Math 8; the card pairing game is highly valid based on the result of the validation; Students exposed to card pairing game become more intact (homogeneous; Students exposed to card games enhance academic performance. It is recommended to test the effectiveness of card pairing games to other group of students; Encourage math teachers to use the developed math card pairing games for classroom instruction; Develop other card pairing game for specific topics in math.

    Efficacious patient safety monitoring should focus on the implementation of evidence-based practices that avoid unnecessary harm related to healthcare. The ISEP-Brazil project aimed to develop and validate indicators for best patient safety practices in Brazil. The basis was the translation and adaptation of the indicators validated in the ISEP-Spain project and the document Safe Practices for Better Healthcare (U.S. National Quality Forum), recommending 34 best practices. A 25-member expert panel validated the indicators. Reliability and feasibility were based on a pilot study in three hospitals with different management formats (state, federal, and private). Seventy-five best practice indicators were approved (39 structure; 36 process) for 31 of the 34 recommendations. The indicators were considered valid, reliable, and useful for monitoring patient safety in Brazilian hospitals.

    2007-01-01

    This paper reports the results of three studies conducted to develop, refine, and validate a scale which assessed heterosexual adults' attitudes toward same-sex marriage, the Attitude Toward Same-Sex Marriage Scale (ASSMS). The need for such a scale is evidenced in the increasing importance of same-sex marriage in the political arena of the United States and other nations, as well as the growing body of empirical research examining same-sex marriage and related issues (e.g., Lannutti, 2005; Solomon, Rothblum, & Balsam, 2004). The results demonstrate strong reliability, convergent validity, and predictive validity for the ASSMS and suggest that the ASSMS may be adapted to measure attitudes toward civil unions and other forms of relational recognition for same-sex couples. Gender comparisons using the validated scale showed that in college and non-college samples, women had a significantly more positive attitude toward same-sex marriage than did men.

    2013-07-01

    This study outlines the development and validation of a new 4-dimensional job insecurity measure (JIM). Items were generated from interviews with Australian employees facing an objective threat of job loss. The measure was then validated on a North American sample of 1,004 respondents. Exploratory and confirmatory factor analyses (EFA and CFA) with tests of sample invariance supported an 18-item measurement model consisting of 4 correlated but distinct subscales of insecurity: Job Loss, Job Changes, Marginalization, and Organizational Survival. The results indicate convergent and discriminant validity as well as high internal consistency for the instrument. Significant associations with psychological well-being (job related affective well-being, job satisfaction) and organizational attitudes (organizational commitment, trust in management, intention to resign) established the criterion-related validity of each subscale. These findings support the use of the instrument in academic and applied settings.

    2010-01-01

    Background. We have reported a new equation (CKD-EPI equation) that reduces bias and improves accuracy for GFR estimation compared to the MDRD study equation while using the same four basic predictor variables: creatinine, age, sex and race. Here, we describe the development and validation of this equation as well as other equations that incorporate diabetes, transplant and weight as additional predictor variables. Methods. Linear regression was used to relate log-measured GFR (mGFR) to sex, race, diabetes, transplant, weight, various transformations of creatinine and age with and without interactions. Equations were developed in a pooled database of 10 studies [2/3 (N = 5504) for development and 1/3 (N = 2750) for internal validation], and final model selection occurred in 16 additional studies [external validation (N = 3896)]. Results. The mean mGFR was 68, 67 and 68 ml/min/ 1.73 m2 in the development, internal validation and external validation datasets, respectively. In external validation, an equation that included a linear age term and spline terms in creatinine to account for a reduction in the magnitude of the slope at low serum creatinine values exhibited the best performance (bias = 2.5, RMSE = 0.250) among models using the four basic predictor variables. Addition of terms for diabetes and transplant did not improve performance. Equations with weight showed a small improvement in the subgroup with BMI <20 kg/m2. Conclusions. The CKD-EPI equation, based on creatinine, age, sex and race, has been validated and is more accurate than the MDRD study equation. The addition of weight, diabetes and transplant does not significantly improve equation performance. PMID:19793928

    The instruments that evaluate a student's perception of receiving simulated training are English versions and have not been tested for reliability or validity. The aim of this study was to develop and validate a Chinese version Simulation-Based Learning Evaluation Scale (SBLES). Four stages were conducted to develop and validate the SBLES. First, specific desired competencies were identified according to the National League for Nursing and Taiwan Nursing Accreditation Council core competencies. Next, the initial item pool was comprised of 50 items related to simulation that were drawn from the literature of core competencies. Content validity was established by use of an expert panel. Finally, exploratory factor analysis and confirmatory factor analysis were conducted for construct validity, and Cronbach's coefficient alpha determined the scale's internal consistency reliability. Two hundred and fifty students who had experienced simulation-based learning were invited to participate in this study. Two hundred and twenty-five students completed and returned questionnaires (response rate=90%). Six items were deleted from the initial item pool and one was added after an expert panel review. Exploratory factor analysis with varimax rotation revealed 37 items remaining in five factors which accounted for 67% of the variance. The construct validity of SBLES was substantiated in a confirmatory factor analysis that revealed a good fit of the hypothesized factor structure. The findings tally with the criterion of convergent and discriminant validity. The range of internal consistency for five subscales was .90 to .93. Items were rated on a 5-point scale from 1 (strongly disagree) to 5 (strongly agree). The results of this study indicate that the SBLES is valid and reliable. The authors recommend that the scale could be applied in the nursing school to evaluate the effectiveness of simulation-based learning curricula. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Introduction The need for valid, reliable, and objective tools has always been emphasized in studies related to the clinical assessment of nursing students. The aims of this study were to develop and assess the validity and reliability of the tools used to evaluate the clinical pharmacology unit. Methods This study was a methodological one, conducted in 2016. An item pool was developed based on the literature review and personal interviews with faculty members. The tool’s validity was determined through assessment of face validity, content validity, and construct validity, using exploratory factor analysis on the data provided by 264 second- and third-semester nursing students of the Islamic Azad University of Babol University of Medical Sciences. Reliability was determined through internal and external consistency, using a Cronbach’s coefficient of the correlation between classes. Results Based on the exploratory factor analysis, all items with a special value of >1 were grouped into six factors: 1) professional behavior; 2) effective communication; 3) recognition of medical terminology; 4) nursing actions before administering medicine; 5) nursing actions while administering medicine; and 6) nursing actions after administering medicine. These factors explained 77% of the total variance of the concept of assessment of the clinical pharmacology unit. In this study, reliability was demonstrated by a Cronbach’s alpha coefficient of 0.96; the correlation coefficient between floors for the total tool was 0.91, ranging from 0.64 to 0.89 in its dimensions. Conclusion The evaluation tool of the clinical pharmacology unit has an acceptable construct validity and satisfactory reliability and validity. Therefore, it can be used to evaluate the clinical pharmacology unit in the nursing education system in Iran. PMID:28008285

    Patient in-session interpersonal behavior, as part of the therapeutic alliance, is an important aspect of the psychotherapy process and impacts treatment outcome. In the present study, the development and validation of a rating scale of patient in-session interpersonal behavior is described. A 10-item rating scale, the Assessment Form of Patient Interpersonal Behavior (AFPIB), was developed using an inductive procedure. The AFPIB was then validated in a sample of patients with hypochondriasis (N = 30), by having two independent raters assess patients' interpersonal behaviors shown in videotaped psychotherapy sessions (N = 60). The AFPIB demonstrated good reliability and validity. Thus, the AFPIB seems to be a promising rating scale for the assessment of patient interpersonal behavior shown in psychotherapy sessions.

  15. Test validity and performance validity: considerations in providing a framework for development of an ability-focused neuropsychological test battery.

    Larrabee, Glenn J

    2014-11-01

    Literature on test validity and performance validity is reviewed to propose a framework for specification of an ability-focused battery (AFB). Factor analysis supports six domains of ability: first, verbal symbolic; secondly, visuoperceptual and visuospatial judgment and problem solving; thirdly, sensorimotor skills; fourthly, attention/working memory; fifthly, processing speed; finally, learning and memory (which can be divided into verbal and visual subdomains). The AFB should include at least three measures for each of the six domains, selected based on various criteria for validity including sensitivity to presence of disorder, sensitivity to severity of disorder, correlation with important activities of daily living, and containing embedded/derived measures of performance validity. Criterion groups should include moderate and severe traumatic brain injury, and Alzheimer's disease. Validation groups should also include patients with left and right hemisphere stroke, to determine measures sensitive to lateralized cognitive impairment and so that the moderating effects of auditory comprehension impairment and neglect can be analyzed on AFB measures.

    We developed a novel procedure specific simulation platform for robotic partial nephrectomy. In this study we prospectively evaluate its face, content, construct and concurrent validity. This hybrid platform features augmented reality and virtual reality. Augmented reality involves 3-dimensional robotic partial nephrectomy surgical videos overlaid with virtual instruments to teach surgical anatomy, technical skills and operative steps. Advanced technical skills are assessed with an embedded full virtual reality renorrhaphy task. Participants were classified as novice (no surgical training, 15), intermediate (less than 100 robotic cases, 13) or expert (100 or more robotic cases, 14) and prospectively assessed. Cohort performance was compared with the Kruskal-Wallis test (construct validity). Post-study questionnaire was used to assess the realism of simulation (face validity) and usefulness for training (content validity). Concurrent validity evaluated correlation between virtual reality renorrhaphy task and a live porcine robotic partial nephrectomy performance (Spearman's analysis). Experts rated the augmented reality content as realistic (median 8/10) and helpful for resident/fellow training (8.0-8.2/10). Experts rated the platform highly for teaching anatomy (9/10) and operative steps (8.5/10) but moderately for technical skills (7.5/10). Experts and intermediates outperformed novices (construct validity) in efficiency (p=0.0002) and accuracy (p=0.002). For virtual reality renorrhaphy, experts outperformed intermediates on GEARS metrics (p=0.002). Virtual reality renorrhaphy and in vivo porcine robotic partial nephrectomy performance correlated significantly (r=0.8, p platform displayed face, content and construct validity. Performance in the procedure specific virtual reality task correlated highly with a porcine model (concurrent validity). Future efforts will integrate procedure specific virtual reality tasks and their global assessment. Copyright © 2015

    Objective To develop a new composite disease activity score for gout and provide its first validation. Methods Disease activity has been defined as the ongoing presence of urate deposits that lead to acute arthritis and joint damage. Every measure for each Outcome Measures in Rheumatology core domain was considered. A 3‐step approach (factor analysis, linear discriminant analysis, and linear regression) was applied to derive the Gout Activity Score (GAS). Decision to change treatment or 6‐month flare count were used as the surrogate criteria of high disease activity. Baseline and 12‐month followup data of 446 patients included in the Kick‐Off of the Italian Network for Gout cohort were used. Construct‐ and criterion‐related validity were tested. External validation on an independent sample is reported. Results Factor analysis identified 5 factors: patient‐reported outcomes, joint examination, flares, tophi, and serum uric acid (sUA). Discriminant function analysis resulted in a correct classification of 79%. Linear regression analysis identified a first candidate GAS including 12‐month flare count, sUA, visual analog scale (VAS) of pain, VAS global activity assessment, swollen and tender joint counts, and a cumulative measure of tophi. Alternative scores were also developed. The developed GAS demonstrated a good correlation with functional disability (criterion validity) and discrimination between patient‐ and physician‐reported measures of active disease (construct validity). The results were reproduced in the external sample. Conclusion This study developed and validated a composite measure of disease activity in gout. Further testing is required to confirm its generalizability, responsiveness, and usefulness in assisting with clinical decisions. PMID:26815286

    2015-06-01

    This study reports on the initial development and validation of the Teacher Subjective Wellbeing Questionnaire (TSWQ) with 2 samples of educators-a general sample of 185 elementary and middle school teachers, and a target sample of 21 elementary school teachers experiencing classroom management challenges. The TSWQ is an 8-item self-report instrument for assessing teachers' subjective wellbeing, which is operationalized via subscales measuring school connectedness and teaching efficacy. The conceptualization and development processes underlying the TSWQ are described, and results from a series of preliminary psychometric and exploratory analyses are reported to establish initial construct validity. Findings indicated that the TSWQ was characterized by 2 conceptually sound latent factors, that both subscales and the composite scale demonstrated strong internal consistency, and that all scales demonstrated convergent validity with self-reported school supports and divergent validity with self-reported stress and emotional burnout. Furthermore, results indicated that TSWQ scores did not differ according to teachers' school level (i.e., elementary vs. middle), but that they did differ according to unique school environment (e.g., 1 middle school vs. another middle school) and teacher stressors (i.e., general teachers vs. teachers experiencing classroom management challenges). Results also indicated that, for teachers experiencing classroom challenges, the TSWQ had strong short-term predictive validity for psychological distress, accounting for approximately half of the variance in teacher stress and emotional burnout. Implications for theory, research, and the practice of school psychology are discussed.

    2012-06-01

    Full Text Available This study discusses the process of developing and validating a conceptual and procedural understanding test for integral calculus. The aim was to produce a valid and reliable test to measure students’ understanding of both types of knowledge, conceptual and procedural, in integral calculus. The test questions were developed in four main stages consisting of eight distinct systematic phases. The validation process started with discussions with content experts followed by a pilot test. Four experts provided inputs for the content validity purposes. Their inputs were used to produce a valid set of Integral Calculus achievement test comprising 15 questions. A pilot test assessed the reliability and fit statistics of the test. The test was administered to 79 students in a higher learning institution selected randomly from a group of students taking Integral Calculus. The data was analyzed using Winstep’s software to ensure the quality of the questions. The analysis was done separately for each construct. The results indicated excellent item reliability indices with very good index separation values for both constructs. However, the person reliability indices for both constructs were only fair to good. Likewise, the results revealed only fair index separation values. In terms of fit statistics, three conceptual understanding items were replaced with a new item. Meanwhile, for procedural understanding items, two items were combined and one misfitting item was modified. Based on the experts’ views and empirical data, the test questions were modified before they were used in the actual study.

    Full Text Available ABSTRACT Objective: to develop and validate an instrument to evaluate the knowledge of health professionals about domestic violence on children. Method: this was a study conducted with 194 physicians, nurses and dentists. A literature review was performed for preparation of the items and identification of the dimensions. Apparent and content validation was performed using analysis of three experts and 27 professors of the pediatric health discipline. For construct validation, Cronbach's alpha was used, and the Kappa test was applied to verify reproducibility. The criterion validation was conducted using the Student's t-test. Results: the final instrument included 56 items; the Cronbach alpha was 0.734, the Kappa test showed a correlation greater than 0.6 for most items, and the Student t-test showed a statistically significant value to the level of 5% for the two selected variables: years of education and using the Family Health Strategy. Conclusion: the instrument is valid and can be used as a promising tool to develop or direct actions in public health and evaluate knowledge about domestic violence on children.

    Objectives To develop and validate brief scales to measure common emotional and behavioural problems among adolescents in the examination-oriented education system and collectivistic culture of China. Setting Middle schools in Hunan province. Participants 5442 middle school students aged 11–19 years were sampled. 4727 valid questionnaires were collected and used for validation of the scales. The final sample included 2408 boys and 2319 girls. Primary and secondary outcome measures The tools were assessed by the item response theory, classical test theory (reliability and construct validity) and differential item functioning. Results Four scales to measure anxiety, depression, study problem and sociality problem were established. Exploratory factor analysis showed that each scale had two solutions. Confirmatory factor analysis showed acceptable to good model fit for each scale. Internal consistency and test–retest reliability of all scales were above 0.7. Item response theory showed that all items had acceptable discrimination parameters and most items had appropriate difficulty parameters. 10 items demonstrated differential item functioning with respect to gender. Conclusions Four brief scales were developed and validated among adolescents in middle schools of China. The scales have good psychometric properties with minor differential item functioning. They can be used in middle school settings, and will help school officials to assess the students’ emotional/behavioural problems. PMID:28062469

    Abstract Currently research exploring paruresis and parcopresis, anxiety relating to urinating and having bowel motions in public respectively is limited. While there are several validated measures of paruresis, no valid measure assessing parcopresis is currently available. The present study investigates the development and validation of the Shy Bladder and Bowel Scale (SBBS) which assesses both paruresis and parcopresis. Two participant groups were utilised to validate this scale, a student psychology cohort (n = 387) and a public cohort (n = 334). An eight-item two-factor model was identified in the psychology cohort and confirmed in the public cohort. The two-factor SBBS was found to be a valid and reliable measure of paruresis and parcopresis. Paruresis and parcopresis-related concerns were associated with social anxiety in both cohorts. Subscales for both paruresis and parcopresis (i.e. difficulty, interference and distress) were positively correlated, suggesting individuals are likely to report similar levels of concerns across both conditions. Further, individuals self-identifying with either paruresis or parcopresis reported significantly higher scores on the respective SBBS subscales than non-identifying paruresis and parcopresis individuals. The SBBS also demonstrated strong test–retest reliability in a small sample of adults (n = 13). Overall, the developed scale provides clinicians and researchers with a valuable tool to evaluate both paruresis and parcopresis. PMID:27216857

    Recently, the number of papers about SFC increased drastically but scientists did not truly focus their work on quantitative performances of this technique. In order to prove the potential of UHPSFC, the present work discussed about the different steps of the analytical life cycle of a method: from development to validation and application. Moreover, the UHPSFC quantitative performances were evaluated in comparison with UHPLC, which is the main technique used for quality control in the pharmaceutical industry and then could be considered as a reference. The methods were developed using Design Space strategy, leading to the optimization of robust method. In this context, when the Design Space optimization shows guarantee of quality, no more robustness study is required prior to the validation. Then, the methods were geometrically transferred in order to reduce the analysis time. The UHPSFC and UHPLC methods were validated based on the total error approach using accuracy profile. Even if UHPLC showed better precision and sensitivity, UHPSFC method is able to give accurate results in a dosing range larger than the 80-120% range required by the European Medicines Agency. Consequently, UHPSFC results are valid and could be used for the control of active substance in a finished pharmaceutical product. Finally, UHPSFC validated method was used to analyse real samples and gave similar results than the reference method (UHPLC).

    Full Text Available Introduction: Emotional words in comparison with neutral words have different hemispheric specialization. It is assumed that the right hemisphere has a role in processing every kind of emotional word. The objective of the present study was the development of a Persian version of the dichotic emotional word test and evaluate its validation among adult Persian speakers.   Materials and Methods: The present study was done on 60 adults, with the age ranging from 18-30 years for both genders, who had no history of neurological disorders with normal hearing. The developed test included eight main lists; each had several dichotic emotional/ neutral pairs of words. Participants were asked to recall as many words in each list as they could after they listened to them. A content validity index was used to analyze the validity of the test.   Results: The mean content validity index score was 0.94. The findings showed that in the left ear, emotional words were remembered more than neutral ones (P=0.007. While in the right ear, neutral words were remembered more (P=0.009. There were no significant differences in male and female scores.   Conclusion:  Dichotic emotional word test has a high content validity. The ability to remember emotional words better in the left ear supports the dominant role of the right hemisphere in emotional word perception.

    The aim of this study was to develop a valid assessment tool to guide clinical education and evaluate students' performance in clinical nursing education. The development of the Clinical Assessment Tool for Nursing Education (CAT-NE) was based on the theory of nursing as professional caring and the Bologna learning outcomes. Benson and Clark's four steps of instrument development and validation guided the development and assessment of the tool. A mixed-methods approach with individual structured cognitive interviewing and quantitative assessments was used to validate the tool. Supervisory teachers, a pedagogical consultant, clinical expert teachers, clinical teachers, and nursing students at the University of Akureyri in Iceland participated in the process. This assessment tool is valid to assess the clinical performance of nursing students; it consists of rubrics that list the criteria for the students' expected performance. According to the students and their clinical teachers, the assessment tool clarified learning objectives, enhanced the focus of the assessment process, and made evaluation more objective. Training clinical teachers on how to assess students' performances in clinical studies and use the tool enhanced the quality of clinical assessment in nursing education.

    2013-06-01

    Impression motivation is an important individual difference variable that has been under-researched in sport psychology, partly due to having no appropriate measure. This study was conducted to design a measure of impression motivation in team-sport athletes. Construct validity checks decreased the initial pool of items, factor analysis (n = 310) revealed the structure of the newly developed scale, and exploratory structural equation modeling procedures (n = 406) resulted in a modified scale that retained theoretical integrity and psychometric parsimony. This process produced a 15-item, 4-factor model; the Impression Motivation in Sport Questionnaire-Team (IMSQ-T) is forwarded as a valid measure of the respondent's dispositional strength of motivation to use self-presentation in striving for four distinct interpersonal objectives: self-development, social identity development, avoidance of negative outcomes, and avoidance of damaging impressions. The availability of this measure has contributed to theoretical development, will facilitate research, and offers a tool for use in applied settings.

    Vibrations are inherently present in nuclear reactors, especially in cores and steam generators of pressurized water reactors (PWR). They can have significant effects on local heat transfer and wear and tear in the reactor and often set safety margins. The simulation of these multiphysics phenomena from first principles requires the coupling of several codes, which is one the most challenging tasks in modern computer simulation. Here an ambitious multiphysics multidisciplinary validation campaign is conducted. It relied on an integrated team of experimentalists and code developers to acquire benchmark and validation data for fluid-structure interaction codes. Data are focused on PWR fuel bundle behavior during seismic transients.

    Full Text Available OBJECTIVE: This study was designed to investigate the revised and short version of the smartphone addiction scale and the proof of its validity in adolescents. In addition, it suggested cutting off the values by gender in order to determine smartphone addiction and elaborate the characteristics of smartphone usage in adolescents. METHOD: A set of questionnaires were provided to a total of 540 selected participants from April to May of 2013. The participants consisted of 343 boys and 197 girls, and their average age was 14.5 years old. The content validity was performed on a selection of shortened items, while an internal-consistency test was conducted for the verification of its reliability. The concurrent validity was confirmed using SAS, SAPS and KS-scale. Receiver operating characteristics analysis was conducted to suggest cut-off. RESULTS: The 10 final questions were selected using content validity. The internal consistency and concurrent validity of SAS were verified with a Cronbach's alpha of 0.911. The SAS-SV was significantly correlated with the SAS, SAPS and KS-scale. The SAS-SV scores of gender (p<.001 and self-evaluation of smartphone addiction (p<.001 showed significant difference. The ROC analysis results showed an area under a curve (AUC value of 0.963(0.888-1.000, a cut-off value of 31, sensitivity value of 0.867 and specificity value of 0.893 in boys while an AUC value of 0.947(0.887-1.000, a cut-off value of 33, sensitivity value of 0.875, and a specificity value of 0.886 in girls. CONCLUSIONS: The SAS-SV showed good reliability and validity for the assessment of smartphone addiction.

    2010-02-01

    Full Text Available Abstract Background The use of prescription anti-obesity medication (AOM is becoming increasingly common as treatment options grow and become more accessible. However, AOM may not be without a wide range of potentially negative impacts on patient functioning and well being. The Treatment Related Impact Measure (TRIM-Weight is an obesity treatment-specific patient reported outcomes (PRO measure designed to assess the key impacts of prescription anti-obesity medication. This paper will present the validation findings for the TRIM-Weight. Methods The online validation battery survey was administered in four countries (the U.S., U.K., Australia, and Canada. Eligible subjects were over age eighteen, currently taking a prescription AOM and were currently or had been obese during their life. Validation analyses were conducted according to an a priori statistical analysis plan. Item level psychometric and conceptual criteria were used to refine and reduce the preliminary item pool and factor analysis to identify structural domains was performed. Reliability and validity testing was then performed and the minimally importance difference (MID explored. Results Two hundred and eight subjects completed the survey. Twenty-one of the 43 items were dropped and a five-factor structure was achieved: Daily Life, Weight Management, Treatment Burden, Experience of Side Effects, and Psychological Health. A-priori criteria for internal consistency and test-retest coefficients for the total score and all five subscales were met. All pre-specified hypotheses for convergent and known group validity were also met with the exception of the domain of Daily Life (proven in an ad hoc analysis as well as the 1/2 standard deviation threshold for the MID. Conclusion The development and validation of the TRIM-Weight has been conducted according to well-defined principles for the creation of a PRO measure. Based on the evidence to date, the TRIM-Weight can be considered a brief

  15. Developing and validating the Youth Conduct Problems Scale-Rwanda: a mixed methods approach.

    Directory of Open Access Journals (Sweden)

    Lauren C Ng

    Full Text Available This study developed and validated the Youth Conduct Problems Scale-Rwanda (YCPS-R. Qualitative free listing (n = 74 and key informant interviews (n = 47 identified local conduct problems, which were compared to existing standardized conduct problem scales and used to develop the YCPS-R. The YCPS-R was cognitive tested by 12 youth and caregiver participants, and assessed for test-retest and inter-rater reliability in a sample of 64 youth. Finally, a purposive sample of 389 youth and their caregivers were enrolled in a validity study. Validity was assessed by comparing YCPS-R scores to conduct disorder, which was diagnosed with the Mini International Neuropsychiatric Interview for Children, and functional impairment scores on the World Health Organization Disability Assessment Schedule Child Version. ROC analyses assessed the YCPS-R's ability to discriminate between youth with and without conduct disorder. Qualitative data identified a local presentation of youth conduct problems that did not match previously standardized measures. Therefore, the YCPS-R was developed solely from local conduct problems. Cognitive testing indicated that the YCPS-R was understandable and required little modification. The YCPS-R demonstrated good reliability, construct, criterion, and discriminant validity, and fair classification accuracy. The YCPS-R is a locally-derived measure of Rwandan youth conduct problems that demonstrated good psychometric properties and could be used for further research.

  16. Development, reliability, and validity testing of the Ethical Behavior Test: a measure for nurses' ethical behavior.

    1997-01-01

    The need for reliable and valid measures for ethical behavior of nurses has encouraged the authors to develop a new instrument to measure students' ethical behavior in daily nursing dilemmas. Characteristic of the instrument presented is the inclusion of two fundamental components of ethical behavior: (1) ethical reasoning (and the resulting decision), and (2) the actual implementation of the ethical decision. As for many instruments, Kohlberg's theory of moral development has been used as the conceptual framework. However, Kohlberg's abstract justice orientation was refined by a care perspective and representative nursing dilemmas were used to make the instrument conceptually more appropriate for measuring nurses' ethical behavior. The analysis of the psychometric properties of the instrument has provided several relevant indications for the reliability and validity of the ethical reasoning and implementation scores. The revealed inconsistencies in the Ethical Behavior Test could be satisfactorily interpreted in terms of Kohlberg's theory and related empirical research findings, supporting the reliability of the ethical behavior scores. The content validity rests upon the careful development of the instrument resulting in an optimal mix of dilemmas, arguments and care situations to reveal nurses' ethical behavior and in a substantial degree of correspondence between the concept and operationalization. The congruency between the patterns of ethical behavior and Kohlberg's theoretical insights about ethical reasoning and practice support the construct validity of the instrument.

    The assessment of intervention integrity is essential in psychotherapeutic intervention outcome research and psychotherapist training. There has been little attention given to it in mindfulness-based interventions research, training programs, and practice. To address this, the Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) was developed. This article describes the MBI:TAC and its development and presents initial data on reliability and validity. Sixteen assessors from three centers evaluated teaching integrity of 43 teachers using the MBI:TAC. Internal consistency (α = .94) and interrater reliability (overall intraclass correlation coefficient = .81; range = .60-.81) were high. Face and content validity were established through the MBI:TAC development process. Data on construct validity were acceptable. Initial data indicate that the MBI:TAC is a reliable and valid tool. It can be used in Mindfulness-Based Stress Reduction/Mindfulness-Based Cognitive Therapy outcome evaluation research, training and pragmatic practice settings, and in research to assess the impact of teaching integrity on participant outcome.

    To describe the development of and test the validity and reliability of the Workplace Culture of Health (COH) scale. Exploratory factor analysis and confirmatory factor analysis were performed on data from a health care organization (N = 627). To verify the factor structure, confirmatory factor analysis was performed on a second data set from a medical equipment manufacturer (N = 226). The COH scale included a structure of five orthogonal factors: senior leadership and polices, programs and rewards, quality assurance, supervisor support, and coworker support. With regard to construct validity (convergent and discriminant) and reliability, two different US companies showed the same factorial structure, satisfactory fit statistics, and suitable internal and external consistency. The COH scale represents a reliable and valid scale to assess the workplace environment and culture for supporting health.

    2010-04-01

    This article outlines the development and initial validation of the Controlling Coach Behaviors Scale (CCBS), a multidimensional self-report measure designed to assess sports coaches' controlling interpersonal style from the perspective of self-determination theory (Ryan & Deci, 2002). Study 1 generated a pool of items, based on past literature and feedback from coaches, athletes, and academic experts. The factorial structure of the questionnaire was tested using exploratory and confirmatory factor analyses across Studies 2 and 3. The final CCBS model in Study 3 comprised 4 factors (controlling use of rewards, conditional regard, intimidation, and excessive personal control) and was cross-validated using a third independent sample in Study 4. The scale demonstrated good content and factorial validity, as well as internal consistency and invariance across gender and sport type. Suggestions for its use in research pertaining to the darker side of coaching and sport participation are discussed.

    The aim of this study was to develop and investigate the validity and reliability of the Hospital-in-the-Home (HITH) Dependency Scale (HDS). The HDS is a new instrument designed to measure the dependency of HITH patients. It calculates an overall dependency level by rating four dimensions of the provision of HITH nursing care. Specifically, these dimensions are the complexity of assessment, complexity of treatment, time taken to provide the treatment, and the frequency of treatment. The results of testing the HDS suggest that it is valid in measuring adult medical and surgical HITH patient dependency. The scale demonstrated strong stability over time in test retest procedures over a one month period (r = 0.80, p HDS is a valid, reliable instrument that is quick and easy to use in the HITH setting.

    2008-03-01

    The main objectives in this research were to introduce the concept of team role knowledge and to investigate its potential usefulness for team member selection. In Study 1, the authors developed a situational judgment test, called the Team Role Test, to measure knowledge of 10 roles relevant to the team context. The criterion-related validity of this measure was examined in 2 additional studies. In a sample of academic project teams (N = 93), team role knowledge predicted team member role performance (r = .34). Role knowledge also provided incremental validity beyond mental ability and the Big Five personality factors in the prediction of role performance. The results of Study 2 revealed that the predictive validity of role knowledge generalizes to team members in a work setting (N = 82, r = .30). The implications of the results for selection in team environments are discussed.

    2015-01-01

    Although the negative impact of disruptive clinician behavior on quality health care delivery has gained attention recently, little systematic effort to address this issue has been reported. To facilitate empirical research to reduce disruptive clinician behaviors, an assessment tool (Johns Hopkins Disruptive Clinician Behavior Survey [JH-DCBS]) with 5 discrete subscales was developed using a 2-step design. First a pool of items was generated from focus group studies and the literature, and then a psychometric evaluation of the survey was conducted with a sample of clinicians (N = 1198) practicing in a large urban academic medical center. The results indicated that the tool was reliable (Cronbach α = .79-.91), showed high content validity (Content Validity Index = .97), and had significantly high correlations with theoretically selected variables. The study team concluded that the JH-DCBS provides a valid empirical assessment of disruptive behavior. Assessment results may be used to design strategies to improve the health and safety of practice environments.

    In recent studies of the structure of affect, positive and negative affect have consistently emerged as two dominant and relatively independent dimensions. A number of mood scales have been created to measure these factors; however, many existing measures are inadequate, showing low reliability or poor convergent or discriminant validity. To fill the need for reliable and valid Positive Affect and Negative Affect scales that are also brief and easy to administer, we developed two 10-item mood scales that comprise the Positive and Negative Affect Schedule (PANAS). The scales are shown to be highly internally consistent, largely uncorrelated, and stable at appropriate levels over a 2-month time period. Normative data and factorial and external evidence of convergent and discriminant validity for the scales are also presented.

    We have developed a reliable and valid questionnaire to measure the psychological consequences of screening mammography. The questionnaire measures the effect of screening on an individual's functioning on emotional, social, and physical life domains. Content validity was ensured by extensive review of the relevant literature, discussion with professionals and interviews with attenders at a pilot Breast X-ray Screening Program in Melbourne, Australia. Discriminant validity was assessed by having expert judges sort items into dimensions which they appeared to be measuring. Acceptable levels of concordance (above 80%) with a priori classifications were found. Concurrent validity was demonstrated by comparison of subscale scores of 53 attenders at the Breast X-ray Program with an independent interview assessment of dysfunction on each of the emotional, social and physical dimensions. There was over 79% agreement between interview scores and questionnaire scores for each dimension. Construct validity was confirmed by showing that subscale scores varied in predicted ways. For women who were recalled for further investigation, scores on each subscale measuring negative consequences, were higher at the recall clinic than at screening clinic (emotional: t = -7.28; df = 70; P less than 0.001; physical: t = -2.53; df = 70; P = 0.014; social: t = -2.49; df = 70; P = 0.015). The internal consistency of all subscales was found to be acceptable. This questionnaire is potentially useful for assessing the psychological consequences of the screening process and should have wide application.

    Measurement of health-related quality of life (HRQL) is becoming more important in studies of patients with inflammatory bowel disease. The McMaster IBDQ is the most widely used HRQL instrument for these patients. However, its use with patients in the United Kingdom has not been validated. This study develops and validates a UK version of the McMaster IBDQ (UK IBDQ). The UK IBDQ was tested with two samples of patients for its reliability, validity, reproducibility, and responsiveness. The first sample consisted of 180 patients participating in a randomized clinical trial. The second was recruited from members of the National Association for Colitis and Crohns Disease. Reliability of the subscales and the summary score of the UK IBDQ is demonstrated by Cronbach's alpha and item-total correlations. Their validity is demonstrated by their correlations with SF-36 subscales and an empirical index of disease activity. Good intraclass correlations and responsiveness ratios show their reproducibility and responsiveness. The findings support the reliability, validity, reproducibility, and responsiveness of the UK IBDQ and its acceptability to patients in UK.

    To design and validate a questionnaire to measure visual symptoms related to exposure to computers in the workplace. Our computer vision syndrome questionnaire (CVS-Q) was based on a literature review and validated through discussion with experts and performance of a pretest, pilot test, and retest. Content validity was evaluated by occupational health, optometry, and ophthalmology experts. Rasch analysis was used in the psychometric evaluation of the questionnaire. Criterion validity was determined by calculating the sensitivity and specificity, receiver operator characteristic curve, and cutoff point. Test-retest repeatability was tested using the intraclass correlation coefficient (ICC) and concordance by Cohen's kappa (κ). The CVS-Q was developed with wide consensus among experts and was well accepted by the target group. It assesses the frequency and intensity of 16 symptoms using a single rating scale (symptom severity) that fits the Rasch rating scale model well. The questionnaire has sensitivity and specificity over 70% and achieved good test-retest repeatability both for the scores obtained [ICC = 0.802; 95% confidence interval (CI): 0.673, 0.884] and CVS classification (κ = 0.612; 95% CI: 0.384, 0.839). The CVS-Q has acceptable psychometric properties, making it a valid and reliable tool to control the visual health of computer workers, and can potentially be used in clinical trials and outcome research.

    Full Text Available The purpose of this paper was to report the development and preliminary validation of tactical assessment system in Soccer and highlight its advantages. The validation process followed five perspectives of the concept of validity that consider the value of heuristic methods and the importance of the description of behavior performed in playing situations. Thus, the process of validation was focused on four points: i acceptability and reasonableness of the test perceived by players; ii analysis of content of assessment tool through a panel of experts; iii potential of the assessment tool to discriminate the quality of the performance of players; iv observation reliability. The results displayed values higher than 0.63 for correlation between the evaluations of coaches and the system. It shows the potential of this system to distinguish the performances of players based on the evaluations of coaches. The players who performed the field test agreed with its physical demands and spatial and normative configurations. All experts endorsed the categories and variables of this system. The reliabilities showed values higher than 0.79 for intra and inter-observers. Therefore, it is possible to conclude that the system is valid and reliable for the assessment of the tactical behavior of soccer players.

    Physicians and researchers in the field of family medicine often need to find relevant articles in online medical databases for a variety of reasons. Because a search filter may help improve the efficiency and quality of such searches, we aimed to develop and validate search filters to identify research studies of relevance to family medicine. Using a new and objective method for search filter development, we developed and validated 2 search filters for family medicine. The sensitive filter had a sensitivity of 96.8% and a specificity of 74.9%. The specific filter had a specificity of 97.4% and a sensitivity of 90.3%. Our new filters should aid literature searches in the family medicine field. The sensitive filter may help researchers conducting systematic reviews, whereas the specific filter may help family physicians find answers to clinical questions at the point of care when time is limited.

    The stability-indicating LC assay method was developed and validated for quantitative determination of cefpirome sulfate (CPS) in the presence of degradation products formed during the forced degradation studies. An isocratic HPLC method was developed with Lichrospher RP-18 column, 5 μm particle size, 125 mm x 4 mm column and 12 mM ammonium acetate-acetonitrile (90 : 10 v/v) as a mobile phase. The flow rate of the mobile phase was 1.0 mL/min. Detection wavelength was 270 nm and temperature was 30 degrees C. Cefpirome sulfate as other cephalosporins was subjected to stress conditions of degradation in aqueous solutions including hydrolysis, oxidation, photolysis and thermal degradation. The developed method was validated with regard to linearity, accuracy, precision, selectivity and robustness. The method was applied successfully for identification and determination of cefpirome sulfate in pharmaceuticals and during kinetic studies.

    2006-05-03

    A high performance liquid chromatography (HPLC) method for the detection of traces of LpHse (4-tert-amylphenol and 2-phenylphenol) has been developed and validated. The method was shown to be linear in the range from 0.5 to 10.00 ppm in solution. The method was also shown to be accurate with a recovery of up to 95% by area response for amylphenol and up to 94% by area response for phenylphenol from metal surfaces (4''x4'' un-polished 304 stainless steel plates) by means of swab material. The reproducibility of the method was determined to be 1.61% by area response and 1.52% by height response for amylphenol and 5.40% by area response and 13.77% by height response for phenylphenol from solutions reported as the pooled relative standard deviation. The developed method was also shown to be rugged by comparisons of different preparations by different analysts. The limit of detection was established to be 0.076 ppm by peak area, 0.079 ppm by peak height for amylphenol and 0.34 ppm by peak area, 0.82 ppm by peak height for phenylphenol from solution, and 1.77 ppb by peak area, 1.23 ppm by peak height for amylphenol and 1.23 ppm by peak area, 1.44 ppm by peak height for phenylphenol from recovery from metal studies. The limit of quantitation was established to be 0.25 ppm by peak area, 0.26 ppm by peak height for amylphenol and 1.14 ppm by peak area, 2.73 ppm by peak height for phenylphenol from solution, and 3.89 ppm by peak area, 4.11 ppm by peak height for amylphenol and 4.11 ppm by peak area, 4.79 ppm by peak height for phenylphenol from recovery from metal plates studies. This method can be employed to determine the presence of LpHse residues in cleaned equipments where the detergent was used.

  15. Test Validity and Performance Validity: Considerations in Providing a Framework for Development of an Ability-Focused Neuropsychological Test Battery

    Science.gov (United States)

    Larrabee, Glenn J.

    2014-01-01

    Literature on test validity and performance validity is reviewed to propose a framework for specification of an ability-focused battery (AFB). Factor analysis supports six domains of ability: first, verbal symbolic; secondly, visuoperceptual and visuospatial judgment and problem solving; thirdly, sensorimotor skills; fourthly, attention/working memory; fifthly, processing speed; finally, learning and memory (which can be divided into verbal and visual subdomains). The AFB should include at least three measures for each of the six domains, selected based on various criteria for validity including sensitivity to presence of disorder, sensitivity to severity of disorder, correlation with important activities of daily living, and containing embedded/derived measures of performance validity. Criterion groups should include moderate and severe traumatic brain injury, and Alzheimer's disease. Validation groups should also include patients with left and right hemisphere stroke, to determine measures sensitive to lateralized cognitive impairment and so that the moderating effects of auditory comprehension impairment and neglect can be analyzed on AFB measures.

    Objective To develop a fatigue assessment scale and test its reliability and validity for commercial construction workers. Methods Using a two-phased approach, we first identified items for the development of a Fatigue Assessment Scale for Construction Workers (FASCW) through review of existing scales in the scientific literature, key informant interviews (n=11) and focus groups (3 groups with 6 workers each) with construction workers. The second phase included assessment for the reliability, validity and sensitivity of the new scale using a repeated-measures study design with a convenience sample of construction workers (n=144). Results Phase one resulted in a 16-item preliminary scale that after factor analysis yielded a final 10-item scale with two sub-scales (“Lethargy” and “Bodily Ailment”).. During phase two, the FASCW and its subscales demonstrated satisfactory internal consistency (alpha coefficients were FASCW (0.91), Lethargy (0.86) and Bodily Ailment (0.84)) and acceptable test-retest reliability (Pearson Correlations Coefficients: 0.59–0.68; Intraclass Correlation Coefficients: 0.74–0.80). Correlation analysis substantiated concurrent and convergent validity. A discriminant analysis demonstrated that the FASCW differentiated between groups with arthritis status and different work hours. Conclusions The 10-item FASCW with good reliability and validity is an effective tool for assessing the severity of fatigue among construction workers. PMID:25603944

    Ohno, Shuji; Ohshima, Hiroyuki; Tajima, Yuji; Ohki, Hiroshi

    Thermodynamic consequence in liquid sodium leak and fire accident is one of the important issues to be evaluated when considering the safety aspect of fast reactor plant building. The authors are therefore initiating systematic verification and validation (V&V) activity to assure and demonstrate the reliability of numerical simulation tool for sodium fire analysis. The V&V activity is in progress with the main focuses on already developed sodium fire analysis codes SPHINCS and AQUA-SF. The events to be evaluated are hypothetical sodium spray, pool, or combined fire accidents followed by thermodynamic behaviors postulated in a plant building. The present paper describes that the ‘Phenomena Identification and Ranking Table (PIRT)’ is developed at first for clarifying the important validation points in the sodium fire analysis codes, and that an ‘Assessment Matrix’ is proposed which summarizes both separate effect tests and integral effect tests for validating the computational models or whole code for important phenomena. Furthermore, the paper shows a practical validation with a separate effect test in which the spray droplet combustion model of SPHINCS and AQUA-SF predicts the burned amount of a falling sodium droplet with the error mostly less than 30%.

    Park, Soonhye; Suh, Jeekyung; Seo, Kyungwoon

    2017-04-01

    This paper describes procedures by which two types of measures of Pedagogical Content Knowledge (PCK) were developed and validated: (a) PCK Survey and (b) PCK Rubric. Given the topic-specificity of PCK, the measures centered on photosynthesis as taught in high school classrooms. The measures were conceptually grounded in the pentagon model of PCK and designed to measure indispensable PCK that can be applied to any teacher, in any teaching context, for the given topic. Because of the exploratory nature of the study, the measures focus on two key components of PCK: (a) knowledge of students' understanding in science and (b) knowledge of instructional strategies and representations. Both measures have established acceptable levels of reliability as determined by internal consistency and inter-rater agreement. Evidence related to content validity was gathered through expert consultations, while evidence related to construct validity was collected through analysis of think-aloud interviews and factor analyses. Issues and challenges emerging from the course of the measure development, administration, and validation are discussed with strategies for confronting them. Directions for future research are proposed in three areas: (a) relationships between PCK and teaching experiences, (b) differences in PCK between science teachers and scientists, and (c) relationships between PCK and student learning.

    Pathogen environmental monitoring programs (EMPs) are essential for food processing facilities of all sizes that produce ready-to-eat food products exposed to the processing environment. We developed, implemented, and evaluated EMPs targeting Listeria spp. and Salmonella in nine small cheese processing facilities, including seven farmstead facilities. Individual EMPs with monthly sample collection protocols were designed specifically for each facility. Salmonella was detected in only one facility, with likely introduction from the adjacent farm indicated by pulsed-field gel electrophoresis data. Listeria spp. were isolated from all nine facilities during routine sampling. The overall Listeria spp. (other than Listeria monocytogenes ) and L. monocytogenes prevalences in the 4,430 environmental samples collected were 6.03 and 1.35%, respectively. Molecular characterization and subtyping data suggested persistence of a given Listeria spp. strain in seven facilities and persistence of L. monocytogenes in four facilities. To assess routine sampling plans, validation sampling for Listeria spp. was performed in seven facilities after at least 6 months of routine sampling. This validation sampling was performed by independent individuals and included collection of 50 to 150 samples per facility, based on statistical sample size calculations. Two of the facilities had a significantly higher frequency of detection of Listeria spp. during the validation sampling than during routine sampling, whereas two other facilities had significantly lower frequencies of detection. This study provides a model for a science- and statistics-based approach to developing and validating pathogen EMPs.

    The number of farmers' markets in the United States is growing. Although there are tools to analyze food availability at grocery stores, corner stores, and convenience stores, little research exists about the availability of food types at farmers' markets. This research developed an audit tool to measure the food environment at farmers' markets in rural and urban food environments and examined its psychometric properties, including face validity, interrater reliability, and discriminant validity. The Farmers' Market Audit Tool was reviewed by content experts, revised, and then tested in six farmers' markets by researchers across three states in 2013, including Kentucky, North Carolina, and Montana. Seven food categories were developed, including vegetables, fruits, meats, cheeses, eggs, grains, and samples. Interrater reliability was high within farmers' market across states. As expected, discriminant validity indicated a systematic disagreement within and between states due to seasonality and ability to grow different types of food across different farmers' markets. The total scores assessing the healthfulness of each farmers' market was 38 (range = 28-50). Using the Farmers' Market Audit Tool at farmers' markets is a reliable and valid method to capture the availability of food offerings.

    Full Text Available Teaching tertiary mathematics entails the use of instructional materials which lead to independent learning. The study evaluated the content validity and level of acceptability of a developed worktext in Basic Mathematics 2. It also found the significant difference between the respondents’ evaluation. Likewise, the study found the significant difference in the pretest and posttest performance between experimental and the control group and the difference between the posttest of the experimental and control groups. The study utilized the descriptive comparative method in determining the validity and acceptability of the developed worktext and the difference between the evaluation of experts/teachers and the student respondents. Quasi-experimental design was also used to find out if the worktext is effective in teaching the course employing t-test for correlated samples and t-test for independent samples. The result showed that the content validity and acceptability is very much valid and very much acceptable. The difference in the post-test between the experimental and the control groups was significant. It is concluded that the worktext is effective to be used in teaching the course.

    Depression among older adults is under-recognized either in the community or in general hospitals in Chinese culture. This study aimed to develop a culturally appropriate screening instrument for late-life depression in the non-psychiatric settings and to test its reliability and validity for a diagnosis of depression. Using a Delphi method, we developed a geriatric depression inventory (GDI), consisting of 12 core symptoms of depressive disorder in old age. We investigated its reliability and validity on 89 patients with late-life depression and 249 non-depression controls. Both self-report (GDI-SR) and physician-interview (GDI-RI) versions were assessed. Cronbach's α coefficient was 0.843 for GDI-SR and 0.880 for GDI-RI. Both GDI-SR and GDI-RI showed good concurrent validity with the 15-item Geriatric Depression Scale (GDS-15) (GDI-SR: r = 0.750, p depression versus non-depression. Using a cut-off of three items endorsed, sensitivity and specificity were 92.1% and 81.9% for GDI-SR, and 93.3% and 87.1% for GDI-RI. The GDI, either based on self-report or rater interview, is a reliable and valid instrument for the detection of depression among older adults in non-psychiatric medical settings in Chinese culture.

    Risk-taking propensity can be influenced by sensation-seeking traits and self-perceived invincibility. We hypothesized that the latter factor may reflect a stable trait that endures across situations and may influence risk-taking behavior. We developed and validated a 20-item scale, the Invincibility Belief Index (IBI) to measure this construct. The IBI demonstrated good internal consistency and excellent test-retest reliability in the development sample (n = 100) and sustained similar levels of reliability in a cross-validation sample (n = 74). Principal components analysis yielded three orthogonal factors measuring self-perceived impunity (immunity from consequences), boldness/audacity (self-assuredness and competitiveness), and adroitness (mental agility and survival skill). In the prediction of risk taking, IBI scores contributed additional unique variance beyond sensation-seeking scores alone. IBI scores demonstrated convergent and discriminant validity with concurrently administered measures. These preliminary results support the reliability and validity of the IBI as a brief measure of self-perceived vulnerability-invincibility in the face of adversity.

    The acute lymphocytic leukemia is a hematopoietic cancer that occurs predominantly in children. Methotrexate is one of the most useful drugs in cancer chemotherapy. The aim of the study was to develop and validate the methodology of high performance liquid chromatography (HPLC) with ultraviolet detection for methotrexate dosage and to determine its concentration in plasma samples from children with leukemia. The study included patients from the outpatient care of pediatric oncology at the Faculty of Medicine of ABC carriers in treatment of leukemia. The study was conducted in chromatographic model Agilent 1100 with UV detector at 302 nm and by the method of ELISA microplate reader capable of reading absorbance at 450 nm. We obtained satisfactory results of selectivity, accuracy, linearity, limit of quantification (LOQ), limit of detection (LOD), precision and robustness and apply the basic criteria for validation as RE No. 899, of May 29, 2003 Guide validation of analytical and bioanalytical National Agency Health Surveillance (ANVISA). We conclude that results for linearity/concentration range, precision, robustness, limit of quantification and detection limits are within the acceptance criteria defined by ANVISA and that the developed analytical method is valid and feasible to be used as a tool in monitoring therapy of methotrexate.

    PURPOSE: The purpose of this paper is to describe the development and validation of a multi-dimensional instrument to measure servant leadership. DESIGN/METHODOLOGY/APPROACH: Based on an extensive literature review and expert judgment, 99 items were formulated. In three steps, using eight samples totaling 1571 persons from The Netherlands and the UK with a diverse occupational background, a combined exploratory and confirmatory factor analysis approach was used. This was followed by an analysis of the criterion-related validity. FINDINGS: The final result is an eight-dimensional measure of 30 items: the eight dimensions being: standing back, forgiveness, courage, empowerment, accountability, authenticity, humility, and stewardship. The internal consistency of the subscales is good. The results show that the Servant Leadership Survey (SLS) has convergent validity with other leadership measures, and also adds unique elements to the leadership field. Evidence for criterion-related validity came from studies relating the eight dimensions to well-being and performance. IMPLICATIONS: With this survey, a valid and reliable instrument to measure the essential elements of servant leadership has been introduced. ORIGINALITY/VALUE: The SLS is the first measure where the underlying factor structure was developed and confirmed across several field studies in two countries. It can be used in future studies to test the underlying premises of servant leadership theory. The SLS provides a clear picture of the key servant leadership qualities and shows where improvements can be made on the individual and organizational level; as such, it may also offer a valuable starting point for training and leadership development.

    Validation of remote sensing land products is a fundamental issue for Earth observation. Ministry of Science and Technology of the People's Republic of China (MOST) has launched a high-tech R&D Program named `Development and experimental verification of key techniques to validate remote sensing products' in 2011. This paper introduces the background, scientific objectives, research contents of this project and research result already achieved. The objectives of this project include (1) to build a technical specification for the validation of remote sensing products; (2) to investigate the performance, we will carry out a comprehensive remote sensing experiment on satellite - aircraft - ground truth and then modify Step 1 until reach the predefined requirement; (3) to establish a validation network of China for remote sensing products. In summer 2012, with support of the Heihe Watershed Allied Telemetry Experimental Research (HiWATER), field observations have been successfully conducted in the central stream of the Heihe River Basin, a typical inland river basin in northwest China. A flux observation matrix composed of eddy covariance (EC) and large aperture scintillometer (LAS), in addition to a densely distributed eco-hydrological wireless sensor network have been established to capture multi-scale heterogeneities of evapotranspiration (ET), leaf area index (LAI), soil moisture and temperature. Airborne missions have been flown with the payloads of imaging spectrometer, light detection and ranging (LiDAR), infrared thermal imager and microwave radiometer that provide various scales of aerial remote sensing observations. Satellite images with high resolution have been collected and pre-processed, e.g. PROBA-CHRIS and TerraSAR-X. Simultaneously, ground measurements have been conducted over specific sampling plots and transects to obtain validation data sets. With this setup complex problems are addressed, e.g. heterogeneity, scaling, uncertainty, and eventually to

    Background Pharmacists work within a highly-regulated occupational sphere, and are bound by strict legal frameworks and codes of professional conduct. This regulatory environment creates the potential for moral distress to occur due to the limitations it places on acting in congruence with moral judgements. Very little research regarding this phenomenon has been undertaken in pharmacy: thus, prominent research gaps have arisen for the development of a robust tool to measure and quantify moral distress experienced in the profession. Objective The aim of this study was to develop an instrument to measure moral distress in community pharmacists. Setting Community pharmacies in the United Kingdom. Method This study adopted a three-phase exploratory sequential mixed-method design. Three semi-structured focus groups were then conducted to allow pharmacists to identify and explore scenarios that cause moral distress. Each of the identified scenarios were developed into a statement, which was paired with twin seven-point Likert scales to measure the frequency and intensity of the distress, respectively. Content validity, reliability, and construct validity were all tested, and the questionnaire was refined. Main outcome measure The successful development of the valid instrument for use in the United Kingdom. Results This research has led to the development of a valid and reliable instrument to measure moral distress in community pharmacists in the UK. The questionnaire has already been distributed to a large sample of community pharmacists. Conclusion Results from this distribution will be used to inform the formulation of coping strategies for dealing with moral distress.

    Full Text Available Abstract Background Tools to enhance physician searches of Medline and other bibliographic databases have potential to improve the application of new knowledge in patient care. This is particularly true for articles about glomerular disease, which are published across multiple disciplines and are often difficult to track down. Our objective was to develop and test search filters for PubMed, Ovid Medline, and Embase that allow physicians to search within a subset of the database to retrieve articles relevant to glomerular disease. Methods We used a diagnostic test assessment framework with development and validation phases. We read a total of 22,992 full text articles for relevance and assigned them to the development or validation set to define the reference standard. We then used combinations of search terms to develop 997,298 unique glomerular disease filters. Outcome measures for each filter included sensitivity, specificity, precision, and accuracy. We selected optimal sensitive and specific search filters for each database and applied them to the validation set to test performance. Results High performance filters achieved at least 93.8% sensitivity and specificity in the development set. Filters optimized for sensitivity reached at least 96.7% sensitivity and filters optimized for specificity reached at least 98.4% specificity. Performance of these filters was consistent in the validation set and similar among all three databases. Conclusions PubMed, Ovid Medline, and Embase can be filtered for articles relevant to glomerular disease in a reliable manner. These filters can now be used to facilitate physician searching.

    The goal of this study was to develop and validate the Family Motivational Climate Questionnaire (FMCQ). Parental involvement (PI) affects children's academic orientations. However, PI questionnaires had not considered parenting behaviours from the perspective of motivational theories. It was therefore decided to develop the FMCQ. 570 Secondary-School students formed the sample. To validate the FMCQ, confirmatory factor analyses, reliability analysis and correlation and regression analyses were conducted. Children's attribution to parents of perceived change in motivational variables affecting achievement, were used as external criteria. Results support most of the hypotheses either related to the FMCQ structure or to its moderating role as predictor of school achievement and of attribution to parents of changes in different motivational variables --interest, effort, perceived ability, success expectancies, resilience, and satisfaction. The results underline the importance of acting on FMC-components in order to improve Children's motivation and achievement.

    Cyberchondria is a form of anxiety characterised by excessive online health research. It may lead to increased levels of psychological distress, worry, and unnecessary medical expenses. The aim of the present study was to develop a psychometrically sound measure of this dimension. A sample of undergraduate students (N = 208; 64% female) completed a pilot version of the cyberchondria severity scale (CSS) along with the short form version of the depression, anxiety and stress scale (DASS-21). Exploratory factor analysis identified a correlated five factor structure that were labelled 'Compulsion', 'Distress', 'Excessiveness', 'Reassurance Seeking' and 'Mistrust of Medical Professional'. The CSS demonstrated good psychometric properties; the subscales had high internal consistency, along with good concurrent and convergent validity. The CSS may prove useful in a wide variety of future research activities. It may also facilitate the development and validation of interventions for cyberchondria. Copyright © 2014 Elsevier Ltd.

    Many problems that arise when providing pharmacy services may contain some ethical components and the aims of this study were to develop and validate a scale that could assess difficulties of ethical issues, as well as the frequency of those occurrences in everyday practice of community pharmacists. Development and validation of the scale was conducted in three phases: (1) generating items for the initial survey instrument after qualitative analysis; (2) defining the design and format of the instrument; (3) validation of the instrument. The constructed Ethical Issue scale for community pharmacy setting has two parts containing the same 16 items for assessing the difficulty and frequency thereof. The results of the 171 completely filled out scales were analyzed (response rate 74.89%). The Cronbach's α value of the part of the instrument that examines difficulties of the ethical situations was 0.83 and for the part of the instrument that examined frequency of the ethical situations was 0.84. Test-retest reliability for both parts of the instrument was satisfactory with all Interclass correlation coefficient (ICC) values above 0.6, (for the part that examines severity ICC = 0.809, for the part that examines frequency ICC = 0.929). The 16-item scale, as a self assessment tool, demonstrated a high degree of content, criterion, and construct validity and test-retest reliability. The results support its use as a research tool to asses difficulty and frequency of ethical issues in community pharmacy setting. The validated scale needs to be further employed on a larger sample of pharmacists.

    Background The social valorisation of overweight in African populations could promote high-risk eating behaviours and therefore become a risk factor of obesity. However, existing scales to assess body image are usually not accurate enough to allow comparative studies of body weight perception in different African populations. This study aimed to develop and validate the Body Size Scale (BSS) to estimate African body weight perception. Methods Anthropometric measures of 80 Cameroonians and 81 Senegalese were used to evaluate three criteria of adiposity: body mass index (BMI), overall percentage of fat, and endomorphy (fat component of the somatotype). To develop the BSS, the participants were photographed in full face and profile positions. Models were selected for their representativeness of the wide variability in adiposity with a progressive increase along the scale. Then, for the validation protocol, participants self-administered the BSS to assess self-perceived current body size (CBS), desired body size (DBS) and provide a “body self-satisfaction index.” This protocol included construct validity, test-retest reliability and convergent validity and was carried out with three independent samples of respectively 201, 103 and 1115 Cameroonians. Results The BSS comprises two sex-specific scales of photos of 9 models each, and ordered by increasing adiposity. Most participants were able to correctly order the BSS by increasing adiposity, using three different words to define body size. Test-retest reliability was consistent in estimating CBS, DBS and the “body self-satisfaction index.” The CBS was highly correlated to the objective BMI, and two different indexes assessed with the BSS were consistent with declarations obtained in interviews. Conclusion The BSS is the first scale with photos of real African models taken in both full face and profile and representing a wide and representative variability in adiposity. The validation protocol proved its

    (i) To develop the Pharmacy Value-Added Services Questionnaire (PVASQ) using emerging themes generated from interviews. (ii) To establish reliability and validity of questionnaire instrument. Using an extended Theory of Planned Behavior as the theoretical model, face-to-face interviews generated salient beliefs of pharmacy value-added services. The PVASQ was constructed initially in English incorporating important themes and later translated into the Malay language with forward and backward translation. Intention (INT) to adopt pharmacy value-added services is predicted by attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), knowledge and expectations. Using a 7-point Likert-type scale and a dichotomous scale, test-retest reliability (N=25) was assessed by administrating the questionnaire instrument twice at an interval of one week apart. Internal consistency was measured by Cronbach's alpha and construct validity between two administrations was assessed using the kappa statistic and the intraclass correlation coefficient (ICC). Confirmatory Factor Analysis, CFA (N=410) was conducted to assess construct validity of the PVASQ. The kappa coefficients indicate a moderate to almost perfect strength of agreement between test and retest. The ICC for all scales tested for intra-rater (test-retest) reliability was good. The overall Cronbach' s alpha (N=25) is 0.912 and 0.908 for the two time points. The result of CFA (N=410) showed most items loaded strongly and correctly into corresponding factors. Only one item was eliminated. This study is the first to develop and establish the reliability and validity of the Pharmacy Value-Added Services Questionnaire instrument using the Theory of Planned Behavior as the theoretical model. The translated Malay language version of PVASQ is reliable and valid to predict Malaysian patients' intention to adopt pharmacy value-added services to collect partial medicine supply.
