    Since the publication of the Rorschach Inkblot Method (Rorschach, 1921/1942 ), theorists, researchers, and practitioners have been debating the nature of the task, its conceptual foundation, and most important its psychometric properties. The validity of the Rorschach Comprehensive System (CS; Exner, 1974 , 2003; Exner & Weiner, 1995 ) has been supported by several meta-analyses that used different types of nontest external criterion for validating individual variables. In a recent meta-analysis, Mihura, Meyer, Dumitrascu, and Bombel ( 2013 ) found coefficients ranging from modest to excellent for most of the selected CS variables, with 13 of them reported as showing "little to no support." This article focuses on these variables. Although endorsing Mihura et al.'s mainly validating findings, we also suggest that the evidence presented for the little or no validity of these 13 variables is not quite compelling enough to warrant changing their definition or coding, or removing them from the system. We point to some issues concerning the description and interpretation of these variables and the appropriateness of the external criteria used for exploring their validity, and suggest considering these issues in further CS research. Implications of Mihura et al.'s meta-analysis for clinical and forensic practice are discussed.

    Full Text Available Psychometric testing is an important, valuable, widespread and legally protected activity in South Africa. Within the ambit of the organizational context a psychometric policy is required to guide and direct this activity. The purpose of this article is to show how the need for such a policy within an organization can be fulfilled. The article proceeds as follows: firstly, the positioning of a psychometric policy within the overall human resource management of an organization is discussed; secondly, a definition of the term 'psychometric policy' and the aims thereof are given; thirdly, a suggested content for such a policy is outlined; fourthly a method of generating this policy is proposed; and lastly, the role of the psychologist in this regard is indicated.  Opsomming Psigometriese toetsing is 'n belangrike, waardevolle, algemene en wetlik beskermde aktiwiteit in Suid-Afrika. Binne organisatoriese verband word 'n psigometriese beleid benodig om hierdie aktiwiteit te lei en rig. Die doel van hierdie artikel is om aan te toon hoe die behoefte aan sodanige beleid in 'n organisasie vervul kan word. Die artikel verloop soos volg: eerstens, word die plasing van 'n psigometriese beleid binne die algemene menslike hulpbronbestuur van die organisasie bespreek; tweedens, word 'n definisie van die begrip "psigometriese beleid" en die doelwitte daarvan gegee; derdens, word 'n voorgestelde inhoud vir sodanige beleid aan die orde gestel; uierdens, word 'n metode aangedui waarvolgens hierdie beleid daargestel kan word; en laastens, word die rol van die sielkundige in hierdie area aangedui.

    2016-04-01

    Integrating long depression-screening instruments into routine clinical practice and research studies is often impractical, necessitating short-item if not single-item measures with comparable psychometric properties. To examine whether single-item or short depression-screening measures are comparable to a comprehensive screening measure in reliability (i.e., internal consistency and test-retest reliability) and validity (i.e., convergent, concurrent, and predictive validity) in Korean young adults within a Classical Testing Theory framework. A total of 458 students from six nursing colleges in South Korea completed three depression measures: the 20-item Center for Epidemiologic Studies-Depression screening instrument (CES-D; comprehensive measure); the five-item Profile of Mood States-Brief depression subscale (POMS-B depression subscale; short measure); a single-item Likert measure; and a single-item numeric rating scale. Internal consistency reliability was tested by Cronbach's alpha and item-total correlations; test-retest reliability by intraclass correlation coefficient (ICC); convergent validity by correlation with the CES-D; concurrent validity by the correlation with perceived stress level and sleep quality; and predictive validity by receiver operating characteristic curve to predict the two groups with different depression levels. The POMS-B depression subscale was comparable to the comprehensive CES-D scale in internal consistency reliability (alpha=.85); test-retest reliability (ICC=.76); and convergent (r=.81 with CES-D), concurrent (r=.64 with perceived stress level, r=.34 with sleep quality), and predictive validity (area under the curve=.88). The two single-item options were not comparable to the comprehensive CES-D. The short POMS-B depression subscale shows an acceptable balance between practical clinical and research needs and psychometric quality. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Facial identity and facial expression processing are crucial socio-emotional abilities but seem to show only limited psychometric uniqueness when the processing speed is considered in easy tasks. We applied a comprehensive measurement of processing speed and contrasted performance specificity in socio-emotional, social and non-social stimuli from an individual differences perspective. Performance in a multivariate task battery could be best modeled by a general speed factor and a first-order factor capturing some specific variance due to processing emotional facial expressions. We further tested equivalence of the relationships between speed factors and polymorphisms of dopamine and serotonin transporter genes. Results show that the speed factors are not only psychometrically equivalent but invariant in their relation with the Catechol-O-Methyl-Transferase (COMT) Val158Met polymorphism. However, the 5-HTTLPR/rs25531 serotonin polymorphism was related with the first-order factor of emotion perception speed, suggesting a specific genetic correlate of processing emotions. We further investigated the relationship between several components of event-related brain potentials with psychometric abilities, and tested emotion specific individual differences at the neurophysiological level. Results revealed swifter emotion perception abilities to go along with larger amplitudes of the P100 and the Early Posterior Negativity (EPN), when emotion processing was modeled on its own. However, after partialling out the shared variance of emotion perception speed with general processing speed-related abilities, brain-behavior relationships did not remain specific for emotion. Together, the present results suggest that speed abilities are strongly interrelated but show some specificity for emotion processing speed at the psychometric level. At both genetic and neurophysiological levels, emotion specificity depended on whether general cognition is taken into account or not. These

    2013-07-01

    Full Text Available This research seeks to identify possible predictors of the difficulty level of reading comprehension items used in a standardized psychometric test for university admission. Several potential predictors of difficulty were proposed, namely, propositional density, negations, grammatical structure, vocabulary difficulty, presence of enhancement elements (words highlighted typographically, item abstraction level and degree of similarity between correct option and relevant text to resolve the item. By Linear Logistic Test Model (Fisher, 1973 it was found that the number of propositions, the syntactic structure, and fundamentally, the presence of difficult words contributed to the prediction of the item difficulty level.

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

    2017-01-01

    Risk characteristics within a psychometric paradigm have been of major concern in studies of food risk perception. This study compared the influence of psychometric factors, perceivers' characteristics (i.e., risk attitude, trust, and favorability of the country of origin), and that of the news media on the levels of food risk perception. The interaction of news media with the other two factors was also examined. A nationwide survey (n = 1,500) was conducted. The foods under investigation were Chinese processed foods and Japanese seafood imported to South Korea. In both cases, hierarchical multiple regression analyses revealed that psychometric factors had the greatest influence on food risk perception, followed by perceivers' characteristics and media use. In addition, our results showed that the effect of perceived benefit and dread in Chinese food were salient only for those with little media use. The implication of the interaction effect on food risk perception is discussed in terms of accessibility and limited capacity of information processing.

    2006-02-01

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

    Within a hybrid strong/weak coupling model for jets in strongly coupled plasma, we explore jet modifications in ultra-relativistic heavy ion collisions. Our approach merges the perturbative dynamics of hard jet evolution with the strongly coupled dynamics which dominates the soft exchanges between the fast partons in the jet shower and the strongly coupled plasma itself. We implement this approach in a Monte Carlo, which supplements the DGLAP shower with the energy loss dynamics as dictated by holographic computations, up to a single free parameter that we fit to data. We then augment the model by incorporating the transverse momentum picked up by each parton in the shower as it propagates through the medium, at the expense of adding a second free parameter. We use this model to discuss the influence of the transverse broadening of the partons in a jet on intra-jet observables. In addition, we explore the sensitivity of such observables to the back-reaction of the plasma to the passage of the jet.

    Full Text Available Task-based language teaching (TBLT is an instructional approach that aims to develop learners’ communicative competence and focuses on the use of tasks as the main unit of instruction. The aim of this study is to investigate the effectiveness of strong and weak versions of TBLT approach over more traditional approaches in improving reading comprehension of Iranian elementary-level EFL learners. Moreover, the distinction between the strong and weak versions of this approach is taken into account in order to investigate which version is more beneficial over the other version. To achieve the objective, 90 male learners in the 15-17 age range who were studying in an institute in Rasht were selected. The findings showed that utilizing both versions of TBLT approach can provide tremendous opportunities for learners to enhance their reading comprehension compared to traditional language teaching methods. More specifically, the results of this study revealed that the use of the weak version of TBLT approach leads the learners to more proficiency in reading comprehension. It is worth pointing out that this study was conducted with Iranian male elementary-level EFL learners in the 15-17 age range studying in Soroush English Institute in Rasht, Iran. It indicates that a small size of population, a specific age range, and male gender were considered. Thus, for other researchers, more participants at different proficiency levels, with other ranges of age, and both genders may be considered in order to make broader generalization about the results.

    We present a comparative study of ring current dynamics during strong and moderate storms. The ring current during the strong storm is studied with IMAGE/HENA data near the solar cycle maximum in 2000. The ring current during the moderate storm is studied using energetic neutral atom (ENA) data from the Two Wide-Angle Imaging Neutral- Atom Spectrometers (TWINS) mission during the solar minimum in 2008. For both storms, the local time distributions of ENA emissions show signatures of postmidnight enhancement (PME) during the main phases. To model the ring current and ENA emissions, we use the Comprehensive Ring Current Model (CRCM). CRCM results show that the main-phase ring current pressure peaks in the premidnight-dusk sector, while the most intense CRCM-simulated ENA emissions show PME signatures. We analyze two factors to explain this difference: the dependence of charge-exchange cross section on energy and pitch angle distributions of ring current. We find that the IMF By effect (twisting of the convection pattern due to By) is not needed to form the PME. Additionally, the PME is more pronounced for the strong storm, although relative shielding and hence electric field skewing is well developed for both events.

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

    Abstract Background The quality of the Educational environment is a key determinant of a student centred curriculum. Evaluation of the educational environment is an important component of programme appraisal. In order to conduct such evaluation use of a comprehensive, valid and reliable instrument is essential. One of most widely used contemporary tools for evaluation of the learning environment is the Dundee Ready Education Environment Measure (DREEM). Apart from the initial psychometric evaluation of the DREEM, few published studies report its psychometric properties in detail. The aim of this study was to examine the psychometric quality of the DREEM measure in the context of medical education in Ireland and to explore the construct validity of the device. Methods 239 final year medical students were asked to complete the DREEM inventory. Anonymised responses were entered into a database. Data analysis was performed using PASW 18 and confirmatory factor analysis performed. Results Whilst the total DREEM score had an acceptable level of internal consistency (alpha 0.89), subscale analysis shows that two subscales had sub-optimal internal consistency. Multiple group confirmatory factor analysis (using Fleming\\'s indices) shows an overall fit of 0.76, representing a weak but acceptable level of fit. 17 of the 50 items manifest fit indices less than 0.70. We sought the best fitting oblique solution to the 5-subscale structure, which showed large correlations, suggesting that the independence of the separate scales is open to question. Conclusions There has perhaps been an inadequate focus on establishing and maintaining the psychometric credentials of the DREEM. The present study highlights two concerns. Firstly, the internal consistency of the 5 scales is quite variable and, in our sample, appears rather low. Secondly, the construct validity is not well supported. We suggest that users of the DREEM will provide basic psychometric appraisal of the device in future

    The essential underlying foundations of Early Intervention (EI), in which parents/family play a critical role in their child's development, leads us to conclude that their contribution assessing early detection of problems is fundamental. The Ages & Stages Questionnaires (ASQ) is a standardized screening instrument that has been successfully studied in different countries and cultures. Translate and study the psychometrics proprieties of the Portuguese version of the 9, 18 and 30month questionnaires of the Ages and Stages Questionnaires, 3rd edition (ASQ-3). Cross-sectional study. Validity and reliability were studied in a sample of 234 parents of children within 9, 18 and 30months. The results indicated that the questionnaires had good internal consistency, strong agreement between observers and between observations with two weeks interval, and strong Pearson product-moment correlation coefficients between the overall and the total for each domain. The cutoff points (i.e. 2 standard deviations below the mean domain score), that identifies children who should receive further referral for more comprehensive assessment, were close to those determined in the original ASQ-3 psychometric studies. Cronbach's alpha ranging from .42 to .70 and Pearson's r values varies from .22 to .60. Although some weaknesses were noted in psychometric qualities analysis, it can be concluded that the ASQ-PT of 9, 18 and 30months of age fulfills the requirements of a screening tool validated for the Portuguese population.

    2016-12-01

    The aim of this study was to evaluate the psychometric properties of complementary and novel measures of partner interfering and partner supportive behaviors in cancer care (PIB-C and PSB-C). Structured telephone interviews were conducted with 378 women (aged 18-79) in partnered relationships and recruited from the Kentucky Cancer Registry. Psychometric analyses of PIB-C and PSB-C were used to determine scale reliability, and scale construct and predictive validity (correlations with indicators of partner abuse, symptoms of depression, anxiety, and stress after cancer). Cronbach's alpha and split-half calculations indicated excellent internal consistency of the 20-item PIB-C (0.936 and 0.87, respectively) and 12-item PSB-C (0.930 and 0.89). Three thematic clusters for the PIB-C and two for the PSB-C were identified through factor analyses. Regarding construct validity, higher PIB-C and lower PSB-C scores were associated with a measure of psychological impacts from abuse. Predictive validity was suggested through (1) lower PSB-C associated with depression, (2) higher PIB-C associated with anxiety, and (3) higher perceived stress associated with higher PIB-C/lower PSB-C scores. Both PIB-C and PSB-C have strong psychometric properties and distinguish partner behaviors more likely to negatively impact women's depression, anxiety, and stress during cancer care/recovery. Use of these measures may assist clinical teams in comprehensively assessing women patients' home environment to best ensure cancer care/recovery. Copyright © 2015 John Wiley & Sons, Ltd.

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

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

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

    2014-02-01

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

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

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

    Nickitas, Donna M; Fealy, Gerard M; De Natale, Mary L

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

    2004-12-01

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

  6. Strong decoherence

    CERN Document Server

    Gell-Mann, Murray; Gell-Mann, Murray; Hartle, James B

    1997-01-01

    We introduce a condition for the strong decoherence of a set of alternative histories of a closed quantum-mechanical system such as the universe. The condition applies, for a pure initial state, to sets of homogeneous histories that are chains of projections, generally branch-dependent. Strong decoherence implies the consistency of probability sum rules but not every set of consistent or even medium decoherent histories is strongly decoherent. Two conditions characterize a strongly decoherent set of histories: (1) At any time the operators that effectively commute with generalized records of history up to that moment provide the pool from which --- with suitable adjustment for elapsed time --- the chains of projections extending history to the future may be drawn. (2) Under the adjustment process, generalized record operators acting on the initial state of the universe are approximately unchanged. This expresses the permanence of generalized records. The strong decoherence conditions (1) and (2) guarantee wha...

  7. Strong Force

    CERN Document Server

    Without the strong force, there could be no life. The carbon in living matter is synthesised in stars via the strong force. Lighter atomic nuclei become bound together in a process called nuclear fusion. A minor change in this interaction would make life impossible. As its name suggests, the strong force is the most powerful of the 4 forces, yet its sphere of influence is limited to within the atomic nucleus. Indeed it is the strong force that holds together the quarks inside the positively charged protons. Without this glue, the quarks would fly apart repulsed by electromagnetism. In fact, it is impossible to separate 2 quarks : so much energy is needed, that a second pair of quarks is produced. Text for the interactive: Can you pull apart the quarks inside a proton?

    Park, Min Hee; Yang, Sook Ja; Chee, Yeon Kyung

    2016-01-01

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

    2013-02-01

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

    2015-03-01

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

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

    2014-04-01

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

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

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

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

    Spatial neglect has been related to both cortical (predominantly at the temporal-parietal junction) and subcortical (predominantly of the superior longitudinal fasciculus) lesions. The objectives of this observational study were to specify the anatomical relationships of behavioral neglect in activities of daily living (N-ADLs), and the anatomical and psychometric relationships of N-ADLs on one hand and components of neglect (peripersonal neglect and personal neglect) and anosognosia on the other. Forty five patients were analyzed for behavioral difficulties in daily living (on the Catherine Bergego scale) and the main components of neglect (using conventional clinical assessments) during the first months post right hemisphere stroke. Voxel-based lesion-symptom mapping was used to identify brain areas within which lesions explained the severity of bias in each assessment (non-parametric permutation test; p<0.01, one tailed). N-ADLs was associated with lesions centered on the posterior part of the superior temporal gyrus and extending to the temporo-parietal junction, temporo-occipital junction and subcortical white matter (including the superior longitudinal fasciculus). Peripersonal neglect resulted from extended cortical lesions centered on the superior temporal gyrus and the inferior parietal gyrus, with subcortical extension. Personal neglect resulted predominantly from lesions centered on the somatosensory cortex and at a lesser degree on the superior temporal sulcus. Anosognosia resulted from lesions of the posterior inferior temporal gyrus and superior temporal gyrus. In anatomic terms, N-ADLs was strongly related to peripersonal neglect, and those relationships were also shown by the psychometric analysis. In conclusions, superior temporal gyrus and superior longitudinal fasciculus lesions have a pivotal role in N-ADLs. N-ADLs is principally related (anatomically and psychometrically) to peripersonal neglect, and at a lesser degree to anosognosia and

    The use of psychometric tests in personnel selection has been regarded with an extraordinary degree of suspicion and scepticism. This is especially true when selection occurs in respect of a diverse applicant group. Concern is expressed about the seemingly uncritical embracing of specific tenets related to the use of psychometric tests in personnel selection in the absence of any systematic coherent psychometric argument to justify these beliefs. The absence of such a supporting psychometric ...

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

    2017-01-01

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

  8. Exploring the "psychometric paradigm": comparisons between aggregate and individual analyses.

    Science.gov (United States)

    1997-06-01

    The "psychometric paradigm" developed by Slovic, Fischhoff, and Lichtenstein was a landmark in research about public attitudes toward risks. One problem with work, however, was that (at least initially) it did not attempt to distinguish between individuals or groups of people, except "experts" vs. "lay people." This paradigm produced a "cognitive map" of hazards, and the assumption seemed to be that the characteristics identified were inherent attributes of risk. This paper examines the validity of this assumption. A questionnaire survey similar to those designed by Slovic et al. was conducted, but the data were analyzed at both the aggregate level, using mean scores, and at the level of individuals (N = 131 Norwich residents). The results reported here demonstrate that (1) individuals vary in their perception of the same risk issue; (2) individuals vary in their rating of the same risks characteristics on the same risk issue; and (3) some of the strong intercorrelations observed between risk characteristics at the aggregate level are not supported when the same data are analysed at the level of individuals. Despite these findings, the relationship between risk characteristics and risk perceptions inferred by the psychometric paradigm did hold true at the level of individuals, for most--but not all--of the characteristics. In particular, the relationship between "lack of knowledge to those exposed" and risk perceptions appears to be a complex one, a finding which has important implications for risk communication strategies.

  9. The psychometric refinement of the Materials Concept Inventory (MCI)

    Corkins, James

    The purpose of this study was to evaluate the psychometric properties of the Materials Concept Inventory (MCI) and then recommend revisions. The MCI was administered to a sample of 303 undergraduate engineering students enrolled in a materials engineering course taught by an instructor unrelated to this study. The MCI demonstrated adequate reliability (Cronbach's alpha was .73) and strong discriminatory power (Ferguson's delta was 0.96). A pretest MCI was given only two days into the course and was able to predict the final course grade (r = .30, p fit by the empirical data [chi-squared (194) = 196.03, p = .426; and root mean square error approximation (RMSEA) was .007; and comparative fit index (CFI) was .996]. The Cronbach's alpha of the refined-MCI was 0.75, suggesting 'good' reliability. The six factors could only be interpreted by an integration of cognitive processes with content. Those six factors were labeled: (1) compare and contrast ductile and brittle material, (2) analyze structure and how it changes due to defects arising from stretching, (3) understand and analyze the structure and properties of glass, (4) analyze structure and how it changes due to defects arising from bending, (5) understand and analyze the structure and properties of metals, and (6) synthesize and apply graphs and proportions with relation to various materials engineering concepts. Results related to the psychometrics of the refined version of the Materials Concept Inventory are promising, but based on this study's results, further revision may be required.

    2014-01-01

    The psychometric screening and detection of schizotypy through the use of concise self-report assessment instruments such as the Schizotypal Personality Questionnaire-Brief Revised (SPQ-BR; Cohen, Matthews, Najolia, & Brown, 2010) enables an expeditious identification of individuals at putatively elevated risk to develop schizophrenia-spectrum disorders. Using 2 large, culturally diverse, independent samples, this study expanded the psychometric evaluation of this instrument by presenting a series of confirmatory factor analyses; reviewing internal consistency reliabilities; and evaluating the construct validity of the scale by way of examining group differences in SPQ-BR scores between individuals with and without self-reported family histories of schizophrenia. The results indicate a 2-tier factor solution of the measure and indicate strong internal reliability for the scale. Findings regarding construct validity of the SPQ-BR are more variable with the Cognitive-Perceptual Deficits superordinate factor receiving the strongest evidentiary support. Limitations of this study and directions for future research are discussed.

    2016-01-01

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

    The current study provides a comprehensive evaluation of critical psychometric properties of commonly used psychophysiology laboratory tasks/measures within the NIMH RDoC. Participants (N = 128) completed the no-shock, predictable shock, unpredictable shock (NPU) task, affective picture viewing task, and resting state task at two study visits separated by 1 week. We examined potentiation/modulation scores in NPU (predictable or unpredictable shock vs. no-shock) and affective picture viewing tasks (pleasant or unpleasant vs. neutral pictures) for startle and corrugator responses with two commonly used quantification methods. We quantified startle potentiation/modulation scores with raw and standardized responses. We quantified corrugator potentiation/modulation in the time and frequency domains. We quantified general startle reactivity in the resting state task as the mean raw startle response during the task. For these three tasks, two measures, and two quantification methods, we evaluated effect size robustness and stability, internal consistency (i.e., split-half reliability), and 1-week temporal stability. The psychometric properties of startle potentiation in the NPU task were good, but concerns were noted for corrugator potentiation in this task. Some concerns also were noted for the psychometric properties of both startle and corrugator modulation in the affective picture viewing task, in particular, for pleasant picture modulation. Psychometric properties of general startle reactivity in the resting state task were good. Some salient differences in the psychometric properties of the NPU and affective picture viewing tasks were observed within and across quantification methods. © 2016 The Authors.

    2009-01-01

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

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

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

    2017-01-01

    Background: Many research participants are misinformed about research terms, procedures, and goals; however, no validated instruments exist to assess individual’s comprehension of health-related research information. We propose research literacy as a concept that incorporates understanding about the purpose and nature of research. Objectives: We developed the Research and Knowledge Scale (RaKS) to measure research literacy in a culturally, literacy-sensitive manner. We describe its development and psychometric properties. Research Design: Qualitative methods were used to assess perspectives of research participants and researchers. Literature and informed consent reviews were conducted to develop initial items. These data were used to develop initial domains and items of the RaKS, and expert panel reviews and cognitive pretesting were done to refine the scale. We conducted psychometric analyses to evaluate the scale. Subjects: The cross-sectional survey was administered to a purposive community-based sample (n=430) using a Web-based data collection system and paper. Measures: We did classic theory testing on individual items and assessed test-retest reliability and Kuder-Richardson-20 for internal consistency. We conducted exploratory factor analysis and analysis of variance to assess differences in mean research literacy scores in sociodemographic subgroups. Results: The RaKS is comprised of 16 items, with a Kuder-Richardson-20 estimate of 0.81 and test-retest reliability 0.84. There were differences in mean scale scores by race/ethnicity, age, education, income, and health literacy (all P<0.01). Conclusions: This study provides preliminary evidence for the reliability and validity of the RaKS. This scale can be used to measure research participants’ understanding about health-related research processes and identify areas to improve informed decision-making about research participation.

    To systematically review and examine the psychometric properties of established resilience scales in older adults, i.e. ≥60 years. A systematic review of Scopus and Web of Science databases was undertaken using the search strategy "resilience" AND (ageing OR aging)". Independent title/abstract and fulltext screening were undertaken, identifying original peer-reviewed English articles that conducted psychometric validation studies of resilience metrics in samples aged ≥60 years. Data on the reliability/validity of the included metrics were extracted from primary studies. Five thousand five hundred nine studies were identified by the database search, 426 used resilience psychometrics, and six psychometric analysis studies were included in the final analysis. These studies conducted analyses of the Connor Davidson Resilience Scale (CD-RISC) and its shortened 10-item version (CD-RISC10), the Resilience Scale (RS) and its shortened 5- (RS-5) and 11- (RS-11) item versions, and the Brief Resilient Coping Scale (BRCS). All scales demonstrated acceptable levels of internal consistency, convergent/discriminant validity and theoretical construct validity. Factor structures for the RS, RS-11 and CD-RISC diverged from the structures in the original studies. The RS, RS-5, RS-11, CD-RISC, CD-RISC10 and BRCS demonstrate psychometric robustness adequate for continued use in older populations. However, results from the current study and pre-existing theoretical construct validity studies most strongly support the use of the RS, with modest and preliminary support for the CD-RISC and BRCS, respectively. Future studies assessing the validity of these metrics in older populations, particularly with respect to factor structure, would further strengthen the case for the use of these scales.

    The development and psychometric qualities of a measure using teacher judgment to rate performance in reading comprehension for narrative text is described-the Rating Scales for Academic Skills-Reading Comprehension Narrative (RSAS-RCN). Sixty-five teachers from the third, fourth, and fifth grades of 8 elementary schools completed the measure on 177 students. Each teacher rated students who had been identified through school-based universal screening to be below the 25th percentile, between the 25th and 74th percentile, and at or above the 75th percentile on national normative standards. Results indicated the RSAS-RCN has strong to moderate evidence of (a) 1-week test-retest reliability, (b) concurrent validity with the Group Reading Assessment and Diagnostic Evaluation (GRADE) and end of year state assessment in reading, and (c) significant classification accuracy across student ability levels. Principal component analysis and item response theory (Rasch modeling) indicate the RSAS-RCN is comprised of a single general dimension. Overall, this examination of the RSAS-RCN suggests teacher judgment may be a potentially valuable tool in assessing reading comprehension among upper elementary school students.

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

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

    This study investigates the utility and psychometric properties of a new measure of psychotherapy process, the Alliance Negotiation Scale (ANS; Doran, Safran, Waizmann, Bolger, & Muran, 2012). The ANS was designed to operationalize the theoretical construct of negotiation (Safran & Muran, 2000), and to extend our current understanding of the working alliance concept (Bordin, 1979). The ANS was also intended to improve upon existing measures such as the Working Alliance Inventory (WAI; Horvath & Greenberg, 1986, 1989) and its short form (WAI-S; Tracey & Kokotovic, 1989) by expanding the emphasis on negative therapy process. The present study investigates the psychometric validity of the ANS test scores and interpretation-including confirming its original factor structure and evaluating its internal consistency and construct validity. Construct validity was examined through the ANS' convergence and divergence with several existing scales that measure theoretically related constructs. The results bolster and extend previous findings about the psychometric integrity of the ANS, and begin to illuminate the relationship between negotiation and other important variables in psychotherapy research.

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

    Full text of publication follows: this paper argues that perceptual control is an essential component in human risk evaluation. Control is seen as an integrative concept between the psychometric research paradigm and various psychological theories. The psychometric approach to the study of risk has mainly dealt with the intuitive judgements people do when they are asked to evaluate risky activities and technologies. It shows that people judge risk in relation to the possible consequences and probabilities related to an outcome; the former more typical for the public and the latter more often usedby experts. The psychometric research tradition has concentrated on doing human risk evaluations quantifiable and the reactions predictable. This paper also relates to possible practical implications of this strategy, namely that humans react heterogeneously to different kinds of threats due to perceived control. Theoretical ability to explain and elaborate perceptions of risk, as well as individual reactions, were the main criteria for the literature selection, which includes work on e.g. attribution theory, locus of control, and learned helplessness. Thus, the paper addresses available psychological views for a contribution to a developed theoretical framework for human risk evaluation. It seeks to compare and integrate the psychometric research tradition within social psychological theories. The way in which people find their informational basis for their risk judgements, either from others or from their own perceptions is also discussed. Furthermore, the theories are related to the social and psychological reactions of the Chernobyl accident. The paper concludes that psychological theories can contribute to a more comprehensive framework for the understanding of human risk evaluation, leading to a more coherent and integrative knowledge.

    2015-01-01

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

    2017-03-01

    The purpose of this article is to summarize the psychometric results from studies of the last 25 years of the Overeating Tension Scale, Exercise Tension Scale, Feelings Tension Scale, and Feelings About Weight Tension Scale. These reliable and valid technology-delivered weight management scales can be used by clinicians independently or in combination to longitudinally identify specific triggers of overeating, skipping exercise, feeling low or down, and strong feelings about one's body weight; motivational states, and related tension levels. Through cognitive behavior therapy, individuals can learn to shift to another motivational state and employ healthy coping mechanisms to avoid related negative behaviors. Psychometric results from seven developmental studies are described, including technology-delivery adaptation results from the original paper and pencil versions. Future tension scale development priorities also are discussed.

    This study examined the relationships between codependency and age, gender, self-confidence, autonomy, and succorance, which is the quality of soliciting emotional support from others. The study also tested the validity of the Spann-Fischer Codependency Scale (Fischer, Spann, & Crawford, 1991). Ninety-five undergraduates completed a demographic sheet, the Adjective Check List (Gough & Heilbrun, 1983), the Spann-Fischer Codependency Scale, the Co-Dependents Anonymous Checklist (Whitfield, 1991), and a questionnaire developed for this study based on the work of Hemfelt, Minirth, and Meier (1989). As predicted, codependency was negatively related to self-confidence and positively related to succorance. However, contrary to expectation, a negative relationship between codependency and autonomy was not found. In addition, low self-confidence was the strongest predictor of codependency. Finally, all three measures of codependency were strongly related, attesting to the convergent validity of the Spann-Fischer Codependency Scale. Future studies should further investigate the role of emotional autonomy and codependency and should begin to utilize an experimental approach, making predictions regarding the behavior of codependent and noncodependent persons in experimental situations.

    Peripheral arterial disease (PAD) is generally associated with considerable morbidity and reduced quality of life. Patient-reported outcome measures (PROMs) provide important information about the burden of disease and impact of treatment in affected patients. The objective of the review was to identify and appraise studies reporting the psychometric evaluation of PROMs administered to a specified population of patients with PAD with a view to recommending suitable PROMs. A systematic review of peer-reviewed English language articles was undertaken to identify primary studies reporting psychometric properties of PROMs in English-speaking patients with various stages of PAD. Comprehensive searches were completed up until January 2015. Study selection, data extraction and quality assessment were undertaken independently by at least two researchers. Findings were presented as tabular and narrative summaries based on accepted guidance. Psychometric evaluation of 6 generic and 7 condition-specific PROMs reported in 14 studies contributed data to the review. The frequently reported measure was the SF-36 (n = 11 studies); others included the Walking Impairment Questionnaire (n = 8 studies), EQ-5D (n = 5 studies) and the Vascular Quality of Life Questionnaire (n = 3 studies). Studies included a diverse PAD population and varied in methodology, including approach to validation of PROMs. Various PROMs have been validated in patients with PAD but no study provided evidence of a full psychometric evaluation in the patient population. Careful selection is required to identify reliable and valid PROMs to use in clinical and research settings.

    This study aimed to evaluate the psychometric performance of the six-item Caring Behaviours Inventory in a sample of Australian acute hospital inpatients. Caring is significant for nursing, and exploring the prevalence of staff-caring behaviours is imperative for high-quality acute care. There is a need for psychometrically sound scales that measures caring in acute care, without imposing extensive respondent burden. A cross-sectional survey design was used to distribute the six-item Caring Behaviours Inventory to an Australian sample of hospital inpatients (n = 210) in December 2012. Psychometric evaluation included item performance, construct validity and internal consistency reliability. The six-item Caring Behaviours Inventory had satisfactory psychometric performance as evidenced by normally distributed scores, a uni-dimensional structure explaining 65% of variance in data, a total Cronbach's α of 0·89 and corrected item-total correlations between 0·51-0·82. The six-item Caring Behaviours Inventory had satisfactory estimates of validity and reliability when tested in an Australian sample of acute hospital inpatients. The tool contributes to the literature by being a brief and nonburdensome alternative with seemingly strong psychometric properties to be used in future measures of caring in nursing. The six-item Caring Behaviours Inventory provides a psychometrically tested fundament for reflective clinical discussions on how nurse behaviours facilitate or impede patient experiences of caring. This can benefit quality development in clinical practice as being in tune with patient experiences and expectations is fundamental to high quality services and patient satisfaction. © 2015 John Wiley & Sons Ltd.

  7. Four theorems on the psychometric function.

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

    Full Text Available The use of psychometric tests in personnel selection has been regarded with an extraordinary degree of suspicion and scepticism. This is especially true when selection occurs in respect of a diverse applicant group. Concern is expressed about the seemingly uncritical embracing of specific tenets related to the use of psychometric tests in personnel selection in the absence of any systematic coherent psychometric argument to justify these beliefs. The absence of such a supporting psychometric rationale seems unfortunate in as far as it probably would inhibit the independent critical evaluation of the psychometric merits of these generally accepted beliefs. Specific beliefs related to selection fairness, measurement bias and adverse impact are critically examined.

    Many published studies have employed the Mini-K to measure a single fast-slow life history dimension. However, the internal structure of the Mini-K has not been determined and it is not clear that a single higher order K-factor fits the data. It is also not clear that the Mini-K is measurement invariant across groups such as the sexes. To establish the construct validity of K as well as the broader usefulness of applying life history theory to humans, it is crucial that these psychometric issues are addressed as a part of measure validation efforts. Here we report on three studies that used latent variable modeling and data drawn from two college student samples ( ns = 361 and 300) to elucidate the psychometrics of the Mini-K. We found that (a) the Mini-K had a six dimensional first-order structure, (b) the K-factor provided a parsimonious explanation of the associations among the lower order factors at no significant cost to fit, (c) the Mini-K measured the same K-factor across the sexes, (d) K-factor means did not have the same meaning across the sexes and thus the first-order factors should be used in studies of mean sex differences, and finally, (e) the K-factor was only associated with environment and aspects of mating competition in females. Implications and future directions for life history research are discussed.

    Full Text Available Abstract Background A strong consensus exists for a systematic approach to linguistic validation of patient reported outcome measures (PROMs and discrete methods for assessing their psychometric properties. Despite the need for robust evidence of the appropriateness of measures, transition from linguistic to psychometric validation is poorly documented or evidenced. This paper demonstrates the importance of linking linguistic and psychometric testing through a purposeful stage which bridges the gap between translation and large-scale validation. Findings Evidence is drawn from a study to develop a Welsh language version of the Beck Depression Inventory-II (BDI-II and investigate its psychometric properties. The BDI-II was translated into Welsh then administered to Welsh-speaking university students (n = 115 and patients with depression (n = 37 concurrent with the English BDI-II, and alongside other established depression and quality of life measures. A Welsh version of the BDI-II was produced that, on administration, showed conceptual equivalence with the original measure; high internal consistency reliability (Cronbach’s alpha = 0.90; 0.96; item homogeneity; adequate correlation with the English BDI-II (r = 0.96; 0.94 and additional measures; and a two-factor structure with one overriding dimension. Nevertheless, in the student sample, the Welsh version showed a significantly lower overall mean than the English (p = 0.002; and significant differences in six mean item scores. This prompted a review and refinement of the translated measure. Conclusions Exploring potential sources of bias in translated measures represents a critical step in the translation-validation process, which until now has been largely underutilised. This paper offers important findings that inform advanced methods of cross-cultural validation of PROMs.

    A positive and strong safety culture underpins effective learning from patient safety incidents in health care, including the community pharmacy (CP) setting. To build this culture, perceptions of safety climate must be measured with context-specific and reliable instruments. No pre-existing instruments were specifically designed or suitable for CP within Scotland. We therefore aimed to develop a psychometrically sound instrument to measure perceptions of safety climate within Scottish CPs. The first stage, development of a preliminary instrument, comprised three steps: (i) a literature review; (ii) focus group feedback; and (iii) content validation. The second stage, psychometric testing, consisted of three further steps: (iv) a pilot survey; (v) a survey of all CP staff within a single health board in NHS Scotland; and (vi) application of statistical methods, including principal components analysis and calculation of Cronbach's reliability coefficients, to derive the final instrument. The preliminary questionnaire was developed through a process of literature review and feedback. This questionnaire was completed by staff in 50 CPs from the 131 (38%) sampled. 250 completed questionnaires were suitable for analysis. Psychometric evaluation resulted in a 30-item instrument with five positively correlated safety climate factors: leadership, teamwork, safety systems, communication and working conditions. Reliability coefficients were satisfactory for the safety climate factors (α > 0.7) and overall (α = 0.93). The robust nature of the technical design and testing process has resulted in the development of an instrument with sufficient psychometric properties, which can be implemented in the community pharmacy setting in NHS Scotland. © 2014 John Wiley & Sons, Ltd.

    The field of discourse processing has dissected many of the levels of representation that are constructed when individuals read or listen to connected discourse. These levels include the surface code, the propositional textbase, the referential situation model, the communication context, and the discourse genre. Discourse psychologists have developed models that specify how these levels are mentally represented and how they are dynamically built during comprehension. This chapter focuses on the meaning representations that are constructed when adults read written text, such as literary stories, technical expository text, and experimenter-generated "textoids." Recent psychological models have attempted to account for the identification of referents of referring expressions (e.g. which person in the text does she refer to), the connection of explicit text segments, the establishment of local and global coherence, and the encoding of knowledge-based inferences.

    Psychometric characteristics of the Postconcussion Symptom Inventory (PCSI) were examined in both concussed (n = 633) and uninjured (n = 1,273) 5 to 18 year olds. Parent- and self-report forms were created with developmentally appropriate wording and content. Factor analyses identified physical, cognitive, emotional, and sleep factors; that did not load strongly or discriminate between groups were eliminated. Internal consistency was strong for the total scales (α = 0.8–0.9). Test–retest reliability for the self-report forms was moderate to strong (intraclass coeffecients, ICCs = 0.65–0.89). Parent and self-report concordance was moderate (r = .44–.65), underscoring the importance of both perspectives. Convergent validity with another symptom measure was good (r = .8). Classification analyses indicated greater discriminability from parent report, but caveats to this are presented. With strong psychometric characteristics, the four versions of the PCSI capture important postconcussion symptoms and can be utilized to track recovery from pediatric concussion and guide treatment recommendations.

    For the purpose of developing a comprehensive assessment method of predicting academic and professional success among health professions' students, a set of 12 psychosocial measures were administered and their psychometric properties were examined. Participants were 141 female allied health and 71 female medical students. Alpha and test-retest reliabilities and construct and concurrent validities of the measures were studied, and most of the measures were found to have satisfactory psychometric properties. Comparisons were also made between medical and allied health sciences students using the 12 psychosocial measures. Allied health students scored higher on loneliness, anxiety, depression, and scored lower on perception of general health and perception of their fathers as compared to medical students. Implications of the findings for development of prediction models of academic and professional performance are discussed.

    Comprehensive land use plans and their corresponding regulations play a role in determining the nature of the built environment and community design, which are factors that influence population health and health disparities. To determine the level in which a plan addresses healthy living and active design, there is a need for a systematic, reliable and valid method of analyzing and scoring health-related content in plans and regulations. This paper describes the development and validation of a scoring tool designed to measure the strength and comprehensiveness of health-related content found in land use plans and the corresponding regulations. The measures are scored based on the presence of a specific item and the specificity and action-orientation of language. To establish reliability and validity, 42 land use plans and regulations from across the United States were scored January-April 2016. Results of the psychometric analysis indicate the scorecard is a reliable scoring tool for land use plans and regulations related to healthy living and active design. Intraclass correlation coefficients (ICC) scores showed strong inter-rater reliability for total strength and comprehensiveness. ICC scores for total implementation scores showed acceptable consistency among scorers. Cronbach's alpha values for all focus areas were acceptable. Strong content validity was measured through a committee vetting process. The development of this tool has far-reaching implications, bringing standardization of measurement to the field of land use plan assessment, and paving the way for systematic inclusion of health-related design principles, policies, and requirements in land use plans and their corresponding regulations.

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

    Full Text Available Assessment of Quality of Life in Epilepsy has currently been emphasized to provide comprehensive care to patients. Aim: To develop and standardize and assess the psychometric properties of Bengali version of QOLIE-10 and to assess the relationship of quality of life with seizure variables and presence of psychiatric morbidity. Design: English QOLIE-10 was translated into Bengali by a translation committee using translation-re-translation technique. Inter-rater reliability between the English and Bengali version was assessed during initial practice session held amongst 20 bilingual patients. It was found that item 3 (related to driving was reported to have difficulty in answering by all the patients as none drove any vehicle. Thus, this item was dropped. The inter-rater reliability of the resultant 9 item scale was found to be high (kappa = 0.9. One hundred and seven epilepsy patients attending the Epilepsy clinic were selected for the study if they met the following criteria: age> 15 years, duration of seizure> 1 year, regular intake of antiepileptic drugs, presence of informant and ability to read Bengali. For each patient, demographic and clinical data (seizure frequency, last seizure date, seizure type as per record, medicine intake history and records of past investigations such as EEG was collected. Each patient were administered QOLIE-9 (Bengali and SRQ-24 Bengali version to screen for psychiatric morbidity. Results: The Cronbach′s Alpha coefficient for QOLIE-9 was 0.81, which did not improve if any item was dropped. All items showed strong correlation with the total score. The instrument showed stable factor structure with three factors (Limitation, Depression, Illness effects. However, the item with regard to memory problem did not fit into any of the factors. The QOLIE-9 total showed a significant correlation with the seizure frequency (r = 0.76FNx08. SRQ positive (i.e., suspected psychiatric morbidity cases had higher QOLIE-9 score

    Full Text Available Recent work in animals suggests that the extent of early tactile stimulation by parents of offspring is an important element in early caregiving. We evaluate the psychometric properties of a new parent-report measure designed to assess frequency of tactile stimulation across multiple caregiving domains in infancy. We describe the full item set of the Parent-Infant Caregiving Touch Scale (PICTS and, using data from a UK longitudinal Child Health and Development Study, the response frequencies and factor structure and whether it was invariant over two time points in early development (5 and 9 weeks. When their infant was 9 weeks old, 838 mothers responded on the PICTS while a stratified subsample of 268 mothers completed PICTS at an earlier 5 week old assessment (229 responded on both occasions. Three PICTS factors were identified reflecting stroking, holding and affective communication. These were moderately to strongly correlated at each of the two time points of interest and were unrelated to, and therefore distinct from, a traditional measure of maternal sensitivity at 7-months. A wholly stable psychometry over 5 and 9-week assessments was not identified which suggests that behavior profiles differ slightly for younger and older infants. Tests of measurement invariance demonstrated that all three factors are characterized by full configural and metric invariance, as well as a moderate degree of evidence of scalar invariance for the stroking factor. We propose the PICTS as a valuable new measure of important aspects of caregiving in infancy.

  5. Psychometric equivalence of recorded spondaic words as test items.

    1998-06-01

    In the determination of the speech-reception threshold (SRT), spondaic words are assumed to be homogeneous with respect to intelligibility; and the assumption of equal intelligibility requires that the words be comparable for all signal levels. Previous attempts to assess the equal intelligibility assumption using word thresholds as the sole criterion are not an adequate basis for specifying the equality of intelligibility. In the present study, the recorded spondaic words (Tillman recording) were analyzed in an attempt to create a more homogeneous set of spondaic words for future laboratory work. To achieve this goal, the data reported by Young, Dudley, and Gunter (1982) and data collected in our laboratory were fitted to a logistic function (psychometric function) from which a 50% point (threshold) and slope were obtained. To specify their acoustical parameters, the recorded spondaic words were digitized and the RMS level and duration of each syllable and word were calculated. None of the RMS or duration measures were correlated with word thresholds, so no attempt was made to equate level or duration. On the other hand, when the threshold of each word was adjusted to equal the mean threshold of the set (n = 36), the dispersion among word thresholds and slopes was greatly reduced. Further, we recommend that small sets of "equally intelligible" spondaic words not be used for clinical testing because set size is a strong factor in determining threshold for spondees (Meyer & Bilger, 1997; Punch & Howard, 1985).

    The purpose of this study was to evaluate the psychometric properties of the Shared Decision-Making Inventory-Revised (SDMI-R) to measure four constructs (knowledge, attitudes, self-efficacy, and intent) theoretically defined as vital in discussing the human papillomavirus (HPV) disease and vaccine with clients. The SDMI-R was distributed to a sample (N = 1,525) of school nurses. Correlational matrixes denoted moderate to strong correlations, indicating adequate internal reliability. Reliability for the total instrument was satisfactory (α = .874) along with Attitude, Self-Efficacy and Intent subscales .828, .917, .891, respectively. Exploratory factor analysis revealed five components that explained 75.96% of the variance.

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

    2007-05-01

    This article presents a psychometric evaluation of the Claustrophobia Scale (CS), consisting of one subscale for measuring anxiety (20 items, 0-4) and one for avoidance (18 items, 0-2). Participants were 87 claustrophobic patients and 200 normal controls randomly selected from the community. The results show that CS has excellent internal consistency, high test-retest reliability, concurrent and discriminant validity. The patients and controls differ significantly on the total scores of anxiety and avoidance, as well as on each individual item scores. The CS was also found to be sensitive to change after cognitive behavioral treatment. Preliminary factor analyses yielded two factors for each subscale; "Being in small enclosed spaces" and "Other people present", accounting for large proportions of the variance. The CS is useful both as a state, and as an outcome self-report measure of claustrophobia.

    As the construct of moral injury has gained increased conceptual and empirical attention among military personnel and veterans, preliminary attempts to operationalize and measure the construct have emerged. One such measure is the Moral Injury Event Scale (MIES). The aim of the current study was to further evaluate the MIES's psychometric properties in two military samples: a clinical sample of Air Force personnel and a nonclinical sample of Army National Guard personnel. Exploratory and confirmatory factor analyses across both samples supported a three-factor solution: transgressions by others, transgressions by self, and betrayal. Transgressions-Others was most strongly associated with posttraumatic stress; Transgressions-Self was most strongly associated with hopelessness, pessimism, and anger; and Betrayal was most strongly associated with posttraumatic stress and anger. Results support the construct validity of the MIES, although areas for improvement are indicated and discussed.

  20. Psychometric functions for detection and discrimination with and without flankers

    García-Pérez, Miguel A.; Alcalá-Quintana, Rocío; Woods, Russell L.; Peli, Eli

    2010-01-01

    Recent studies reported that flanking stimuli broaden the psychometric function and lower detection thresholds. We measured psychometric functions for detection and discrimination with and without flankers to investigate whether these effects occur throughout the contrast continuum. Our results confirm that lower detection thresholds with flankers are accompanied by broader psychometric functions. Psychometric functions for discrimination reveal that discrimination thresholds with and without flankers are similar across standard levels, and that the broadening of psychometric functions with flankers disappears as standard contrast increases, to the point that psychometric functions at high standard levels are virtually identical with or without flankers. Threshold-versus-contrast (TvC) curves with flankers only differ from TvC curves without flankers in occasional shallower dippers and lower branches on the left of the dipper, but they run virtually superimposed at high standard levels. We discuss differences between our results and other results in the literature, and how they are likely attributed to the differential vulnerability of alternative psychophysical procedures to the effects of presentation order. We show that different models of flanker facilitation can fit the data equally well, which stresses that succeeding at fitting a model does not validate it in any sense. PMID:21264745

    Belongingness has been identified both as a fundamental human need and as a prerequisite for nursing students' clinical learning. Belongingness has also been associated with students' academic achievement, retention, self-esteem, self-directed learning, and self-efficacy. The Belongingness Scale-Clinical Placement Experience is a valid and reliable measure of nursing students' belongingness scores; however, a Persian version of this scale is not currently available. This study aimed to translate the Belongingness Scale-Clinical Placement Experience into Persian, to evaluate its psychometric properties, and to measure the belongingness experiences of Iranian nursing students. Following translation and initial validity and reliability testing of the scale, 300 nursing students from three universities in Iran completed the survey. Further psychometric testing was undertaken followed by analysis of descriptive statistics. Based on the results of confirmatory factor analysis two items were removed from the scale. The mean score of Persian version of the Belongingness Scale-Clinical Placement Experience was 3.21 (0.57). The whole scale had a high internal consistency (Cronbach's alpha=0.92). The alpha coefficients of the subscales of "self-esteem", "connectedness", and "efficacy" were 0.85, 0.86, and 0.80 respectively. Similar to previous versions of the Belongingness Scale-Clinical Placement Experience, the Persian version demonstrated strong psychometric properties with strong validity and reliability, indicating its utility and appropriateness when measuring Iranian nursing students' belongingness experiences. Further testing with other cohorts would strengthen these results. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The psychological assessment of patients suffering back pain has become a standard part of comprehensive diagnostic protocol and an accepted responsibility of the clinical practitioner. This is for good reason, since research confirms the value of psychological evaluation to clinical diagnosis, treatment planning, and the outcomes of both medical and surgical treatment. However, the traditional psychological tests developed for use with psychiatric patients and in mental health settings are not appropriate for nonpsychiatric orthopaedic patients with back pain. However, a psychometric instrument has recently been developed for use with patients in pain. The Post-Traumatic Personality Profile (P-3) is a 48-item, multiple-choice, paper-and-pencil instrument that takes only 15 to 20 minutes. This article discusses the psychometric properties of the P-3 and presents a typical test interpretation.

    The purpose of the present study was to evaluate, in a sample of young people and adults from the general community, the psychometric properties of two models developed for assessing gambling motives (Gambling Motives Questionnaire and Gambling Motives Questionnaire-Financial; GMQ and GMQ-F). Specifically, a confirmatory factor analysis was carried out to assess the fit of the two models to the data. Internal consistency of the scales was then analyzed. A multiple regression analysis was conducted to analyze the utility of gambling motives for predicting levels of gambling problem severity. The final sample was made up of 341 young people and adults, aged 18 to 60, who reported any gambling activity during the last six months. The maximum likelihood (ML) method with robust Satorra-Bentler correction was used to evaluate the fit of the models to the data. The results indicated that both the GMQ and the GMQ-F models show a reasonable fit to the data. All scales have adequate internal consistency values. Enhancement, coping and financial gambling motives were associated with greater severity of gambling problems. Overall, the results indicate that both models have adequate psychometric properties, though the GMQ-F appears to provide a more comprehensive alternative for assessing gambling motives in the general community.

    Background The Positive and Negative Affect Schedule (PANAS) is a widely used measure of affect, and a comprehensive psychometric evaluation has never been conducted among substance users. Objective To examine the psychometric properties of the PANAS in a sample of outpatient treatment substance users. Methods We used pooled data from four randomized clinical trials (N = 416; 34% female, 48% African American). Results A confirmatory factor analysis indicated adequate support for a two-factor correlated model comprised of Positive Affect and Negative Affect with correlated item errors (Comparative Fit Index = .93, Root Mean Square Error of Approximation = .07, χ2 = 478.93, df = 156). Cronbach’s α indicated excellent internal consistency for both factors (.90 and .91, respectively). The PANAS factors had good convergence and discriminability (Composite Reliability >.7; Maximum Shared Variance < Average Variance Extracted). A comparison from baseline to Week 1 indicated acceptable test-retest reliability (Positive Affect = .80, Negative Affect = .76). Concurrent and discriminant validity were demonstrated with correlations with the Brief Symptom Inventory and Addiction Severity Index. The PANAS scores were also significantly correlated with treatment outcomes (e.g., Positive Affect was associated with the maximum days of consecutive abstinence from primary substance of abuse, r = .16, p = .001). Conclusion Our data suggest that the psychometric properties of the PANAS are retained in substance using populations. Although several studies have focused on the role of Negative Affect, our findings suggest that Positive Affect may also be an important factor in substance use treatment outcomes. PMID:26905228

    The purpose of this study is to establish the psychometric properties of 22 measures from a community-based participatory research (CBPR) conceptual model. The design of this study was an online, cross-sectional survey of academic and community partners involved in a CPBR project. CPBR projects (294) in the United States with federal funding in 2009. Of the 404 academic and community partners invited, 312 (77.2%) participated. Of the 200 principal investigators/project directors invited, 138 (69.0%) participated. Twenty-two measures of CBPR context, group dynamics, methods, and health-related outcomes were examined. Confirmatory factor analysis to establish factorial validity and Pearson correlations to establish convergent and divergent validity were used. Confirmatory factor analysis demonstrated strong factorial validity for the 22 constructs. Pearson correlations (p < .001) supported the convergent and divergent validity of the measures. Internal consistency was strong, with 18 of 22 measures achieving at least a .78 Cronbach α. CBPR is a key approach for health promotion in underserved communities and/or communities of color, yet the basic psychometric properties of CBPR constructs have not been well established. This study provides evidence of the factorial, convergent, and discriminant validity and the internal consistency of 22 measures related to the CBPR conceptual model. Thus, these measures can be used with confidence by both CBPR practitioners and researchers to evaluate their own CBPR partnerships and to advance the science of CBPR.

    Background Psychometric testing is used to identify patients with cirrhosis who have developed hepatic encephalopathy (HE). Most batteries consist of a series of paper-and-pencil tests, which are cumbersome for most clinicians. A modern, easy-to-use, computer-based battery would be a helpful clinical tool, given that in its minimal form, HE has an impact on both patients’ quality of life and the ability to drive and operate machinery (with societal consequences). Aim We compared the Cogstate™ computer battery testing with the Psychometric Hepatic Encephalopathy Score (PHES) tests, with a view to simplify the diagnosis. Methods This was a prospective study of 27 patients with histologically proven cirrhosis. An analysis of psychometric testing was performed using accuracy of task performance and speed of completion as primary variables to create a correlation matrix. A stepwise linear regression analysis was performed with backward elimination, using analysis of variance. Results Strong correlations were found between the international shopping list, international shopping list delayed recall of Cogstate and the PHES digit symbol test. The Shopping List Tasks were the only tasks that consistently had P values of battery correlated very strongly with the digit symbol component of PHES in discriminating severity of HE. These findings would indicate that components of the current PHES battery with the international shopping list tasks of Cogstate would be discriminant and have the potential to be used easily in clinical practice.

    The extent to which Theory of Mind impairments are a trait associated with schizotypy is unclear. To date, findings have been mixed. We compared two groups of psychometrically identified schizotypes, namely, those characterized by positive schizotypy (perceptual aberrations and magical ideation; n=36) and those characterized by negative schizotypy (social anhedonia; n=30) to a low schizotypy comparison group (n=68) in terms of their Theory of Mind performance. Theory of Mind was assessed in two ways: a composite Hinting Task and the Reading the Mind in the Eyes Test. The groups were also compared in terms of their self-reported levels of referential thinking. Our results indicate that individuals characterized by positive schizotypy show Theory of Mind deficits, as measured by the Hinting Task. The three groups did not differ in terms of the Eyes Test. Referential thinking was significantly associated with the Eyes Test but not the Hinting Task. Overall these findings suggest that different aspects of schizotypy are associated differentially with Theory of Mind deficits. The results also provide further rationale for the inclusion of multiple tasks when attempting to study multifaceted constructs such as Theory of Mind. Copyright © 2011 Elsevier Ltd.

    The Cognitive Failures Questionnaire (CFQ) is used in ergonomics research to measure behavioural problems associated with attentiveness and memory in everyday life. CFQ scores have been related to constructs such as accident proneness and outcomes such as human error and psychological strain. The two-year test-retest reliability of the CFQ is reported together with the findings of factor analyses of CFQ data from 535 respondents. Evidence for the predictive and criterion validity and internal reliability of the CFQ is provided. Psychological strain was measured concurrently with CFQ on both testing occasions, two years apart. The test-retest reliability of the summated CFQ score was found to be 0.71, while for the General Health Questionnaire (GHQ-12) strain measure it was 0.32.The relative variance stability was five times greater for the CFQ than the GHQ, indicating that scores on these questionnaires are not covariates. The use of the CFQ as a measure of cognitive control capacity is also discussed. Ergonomists have long been interested in human error and the role of high work demands due to poor equipment design and excessive workload. The CFQ measures attentiveness in daily life and is shown to have excellent psychometric properties that make it suitable for use in both laboratory and field studies as a trait measure of attentiveness in daily life.

    Despite the prevalence of pornography use, and recent conceptualization of problematic use as an addiction, we could find no published scale to measure craving for pornography. Therefore, we conducted three studies employing young male pornography users to develop and evaluate such a questionnaire. In Study 1, we had participants rate their agreement with 20 potential craving items after reading a control script or a script designed to induce craving to watch pornography. We dropped eight items because of low endorsement. In Study 2, we revised both the questionnaire and cue exposure stimuli and then evaluated several psychometric properties of the modified questionnaire. Item loadings from a principal components analysis, a high internal consistency reliability coefficient, and a moderate mean inter-item correlation supported interpreting the 12 revised items as a single scale. Correlations of craving scores with preoccupation with pornography, sexual history, compulsive internet use, and sensation seeking provided support for convergent validity, criterion validity, and discriminant validity, respectively. The enhanced imagery script did not impact reported craving; however, more frequent users of pornography reported higher craving than less frequent users regardless of script condition. In Study 3, craving scores demonstrated good one-week test-retest reliability and predicted the number of times participants used pornography during the following week. This questionnaire could be applied in clinical settings to plan and evaluate therapy for problematic users of pornography and as a research tool to assess the prevalence and contextual triggers of craving among different types of pornography users.

    2008-01-01

    The psychometric properties of the Beck Depression Inventory-II (BDI-II) as a self-administered screening tool for depressive symptoms were examined in a sample of community-dwelling older and younger adults. Participants completed the BDI-II, the Center for Epidemiologic Studies Depression Scale, the Coolidge Axis II Inventory, the Perceived Stress Scale, and the Short Psychological Well-Being Scale. Internal reliability of the BDI-II was found to be good among older and younger adults. The average BDI-II depression score did not differ between younger and older adults. Solid evidence for convergent and discriminant validity was demonstrated by correlations between the BDI-II with the other measures. The BDI-II appears to have strong psychometric support as a screening measure for depression among older adults in the general population. Implications for using the BDI-II as an assessment instrument in behaviorally based psychotherapy are discussed.

    2016-06-01

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

    Although research on Theory-of-Mind (ToM) is often based on single task measurements, more comprehensive instruments result in a better understanding of ToM development. The ToM Storybooks is a new instrument measuring basic ToM-functioning and associated aspects. There are 34 tasks, tapping various emotions, beliefs, desires and mental-physical distinctions. Four studies on the validity and reliability of the test are presented, in typically developing children (n = 324, 3-12 years) and children with PDD-NOS (n = 30). The ToM Storybooks have good psychometric qualities. A component analysis reveals five components corresponding with the underlying theoretical constructs. The internal consistency, test-retest reliability, inter-rater reliability, construct validity and convergent validity are good. The ToM Storybooks can be used in research as well as in clinical settings.

    Full Text Available We review the effects of strong background fields in noncommutative QED. Beginning with the noncommutative Maxwell and Dirac equations, we describe how combined noncommutative and strong field effects modify the propagation of fermions and photons. We extend these studies beyond the case of constant backgrounds by giving a new and revealing interpretation of the photon dispersion relation. Considering scattering in background fields, we then show that the noncommutative photon is primarily responsible for generating deviations from strong field QED results. Finally, we propose a new method for constructing gauge invariant variables in noncommutative QED, and use it to analyse the physics of our null background fields.

    The aim of this study was to investigate the psychometric properties of the Oswestry Disability Index (ODI) in a large cross-sectional cohort of individuals with chronic low back pain by defining its internal consistency, construct structure and validity, and its ability to differentiate between different degrees of functional limitation. A total of 837 consecutive outpatient patients with low back pain were studied. The internal consistency of ODI was assessed by Cronbach's α, construct structure by exploratory factor analysis, construct validity by confirmatory factor analysis, and discrimination was determined by item response theory analysis. The ODI showed good internal consistency (α=0.85). Explanatory factor analysis showed that ODI is a unidimensional test measuring functional level and nothing else. The confirmatory factor analysis showed that the standardized regression weights of all ODI items were relatively high, varying from 0.5 to 0.7. The item response theory analysis suggested that eight out of 10 ODI items have a close to perfect ability to measure functional limitations in accordance with the actual severity of disability experienced by the respondents. Discrimination of all the items was high to perfect (1.08-2.01). The test characteristic and test information curves showed that the discriminative ability of the ODI is superior at higher levels of disability. The present data showed that the ODI is an internally consistent, unidimensional scale with overall excellent construct validity and ability to discriminate the severity of functional disability. The analysis suggests that the ODI may better distinguish between the relative degrees of function at above-average disability levels.

    Elastic neutron scattering plays a key role in establishing the neutron-nucleus potential, i.e., the interaction strength between a neutron and a nucleus. In ADS applications, this information is useful in many different ways. Elastic scattering data are needed when determining the neutron intensity profile in and ADS system. In addition, the optical potentials derived from elastic neutron scattering data are used as input in every model calculation with a neutron in the incident or exit channel. Recently, there has been intense international debate on the neutron-proton scattering cross section. In the global data base, the backward cross section differs by 10% or even more at energies above 100 MeV. It is difficult to overemphasize the importance of this issue. The np scattering cross section is used as cross section reference in essentially all measurements of neutron-induced cross sections. Thus, for many applied cross sections the absolute scale is uncertain by the same amount. Moreover, the np scattering cross section has been used to derive the pion-nucleon coupling constant, i.e., the absolute strength of the strong interaction. It is annoying to have such a large uncertainty for such a fundamental parameter. We are presenting new data on elastic neutron scattering at 96 MeV from {sup 12}C and {sup 208}Pb, where the latter is part of the HINDAS project. In addition, new data on np scattering at 190 MeV will be presented. The impact on ADS and fundamental physics will be discussed. (orig.)

    QUEST+ is a Bayesian adaptive psychometric testing method that allows an arbitrary number of stimulus dimensions, psychometric function parameters, and trial outcomes. It is a generalization and extension of the original QUEST procedure and incorporates many subsequent developments in the area of parametric adaptive testing. With a single procedure, it is possible to implement a wide variety of experimental designs, including conventional threshold measurement; measurement of psychometric function parameters, such as slope and lapse; estimation of the contrast sensitivity function; measurement of increment threshold functions; measurement of noise-masking functions; Thurstone scale estimation using pair comparisons; and categorical ratings on linear and circular stimulus dimensions. QUEST+ provides a general method to accelerate data collection in many areas of cognitive and perceptual science.

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

    Isenberg, James

    2017-01-01

    The Hawking-Penrose theorems tell us that solutions of Einstein's equations are generally singular, in the sense of the incompleteness of causal geodesics (the paths of physical observers). These singularities might be marked by the blowup of curvature and therefore crushing tidal forces, or by the breakdown of physical determinism. Penrose has conjectured (in his `Strong Cosmic Censorship Conjecture`) that it is generically unbounded curvature that causes singularities, rather than causal breakdown. The verification that ``AVTD behavior'' (marked by the domination of time derivatives over space derivatives) is generically present in a family of solutions has proven to be a useful tool for studying model versions of Strong Cosmic Censorship in that family. I discuss some of the history of Strong Cosmic Censorship, and then discuss what is known about AVTD behavior and Strong Cosmic Censorship in families of solutions defined by varying degrees of isometry, and discuss recent results which we believe will extend this knowledge and provide new support for Strong Cosmic Censorship. I also comment on some of the recent work on ``Weak Null Singularities'', and how this relates to Strong Cosmic Censorship.

    2015-12-01

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

    The aim of our study was to report preliminary validation data on the EORTC translated, Polish version of the EORTC QLQ-ELD14 questionnaire to show that this tool is an acceptable and psychometrically robust measure to collect HRQoL data in Polish elderly patients with cancer. Patients with histological confirmation of primary cancer were eligible for the study. All patients filled out the Polish version of the EORTC QLQ-ELD14 module in addition to EORTC QLQ-C30 and a demographic questionnaire. Standardized validity and reliability analyses were performed. Sixty-five patients (41 females - 63.1%) were enrolled into the study, with a mean age of 76.4 ± 5.7 years. Cronbach alpha coefficients, range 0.70-0.84, showed positive internal consistency. Satisfactory convergent and discriminant validity in multi-trait scaling analyses was seen. Strong correlations were observed between the EORTC QLQ-ELD14 (especially mobility and burden of illness), and the EORTC QLQ-C30 (r = -0.30-(-0.83); p EORTC QLQ-ELD14 module is a reliable and valid tool for measuring HRQoL in elderly cancer patients. However further research is needed to establish the full psychometric properties of the described module, especially in regards to test-retest and responsiveness over time.

    It is presented the structure and psychometric studies of the "School Motivation Questionnaire". The SMQ is a self-report questionnaire with 101 items, organized in sixteen scales that measure the students' goal orientations, the perceived classroom goal structures, the perceived teacher's autonomy support and the use of learning strategies. Twelve scales are adapted from the "Learning Climate Questionnaire", "Perceptions of Instrumentality" and "Cuestionário a Estudiantes". Four scales and five additional items are created new. The psychometric studies rely on a convenience sample consisting of 9th and 12th grade students (N = 485) of Portuguese schools. The factorial and construct validity, verified through several exploratory factorial analyses to the data, presents a final solution of six factors, labelled Strategies (F1), Teacher Extrinsic Goals (F2), Student Extrinsic Goals, Externally Regulated (F3) Teacher Intrinsic Goals (F4), Student Extrinsic Goals, Internally Regulated (F5), and Student Intrinsic Goals (F6). The six-factor solution explains a significant variance of the scale results (53.95%). Good coefficients of internal consistency are obtained for all factors, never below (.858; F6). In sum there is strong evidence to support the multi-dimensionality of SMQ, upholding that the data obtained is exploratory and applies for future validation studies.

    Full Text Available The purpose was to describe the development and psychometric properties of the Emotional Intelligence Admission Essay scale. The authors developed an admission essay question and rating scale designed to provide information about applicants’ emotional intelligence (EI. Content validity, convergent validity, interrater reliability, and internal consistency were established. The scale was also examined to determine if it could discriminate between students with and without professional behavior problems in the academic and fieldwork settings. Content validity was found to be high by a panel of three experts in EI (content validity index = 1.0. Convergent validity with the Assessing Emotions Scale was moderate (r = .46, p < .02. Interrater reliability between two trained faculty raters was high (ICC = .91, p < .000. Internal consistency of the scale was high with a Cronbach’s alpha of .95. This version of the scale was not able to discriminate between students with and without professional behavior problems. The moderate to strong psychometric properties suggest that the EI Admission Essay Scale has the ability to provide information about applicants’ EI. The wording of the essay question must be modified to better instruct applicants to address interpersonal conflict.

    Full Text Available Abstract Background This paper reports the psychometric properties of the Chinese version of Craving Beliefs Questionnaire (CCBQ, an easy-to-administer assessment instrument of measurement of craving beliefs for heroin abusers. Methods Participants were 445 heroin abusers from four methadone clinics in Northern Taiwan. Fifty-one of the participants were tested twice within a two-week period at a different hospital to examine test-retest reliability. Results Three-factor solution using principal component analysis was identified in the CCBQ: will power, compulsive behavior, and negative coping, accounting for 54.6% of the variance. Internal consistency analysis indicated that the three factors have strong reliability, with Cronbach alphas ranging from .81 to .92. The test-retest ICC coefficient is .80. The test-retest coefficients for the subscales will power, compulsive behavior, and negative coping are .76, .51, and .64, respectively. Overall, the data show that the CCBQ has acceptable reliability and validity, demonstrating that it can be a research instrument for assessing heroin craving beliefs. Conclusions The psychometric properties of the CCBQ seem promising for both research and clinical purposes, and the scale thus deserves further refinement and validation with heroin abusers.

    2014-05-01

    The Generalized Anxiety Disorder Inventory is a recently developed self-report measure that assesses symptoms of generalized anxiety disorder. Its psychometric properties have not been investigated further since its original development. The current study investigated its psychometric properties in a Canadian student/community sample. Exploratory principal component analysis replicated the original three-component structure. The total scale and subscales demonstrated excellent internal consistency reliability (α = 0.84-0.94) and correlated strongly with the Penn State Worry Questionnaire (r = 0.41-0.74, all ps Generalized Anxiety Disorder-7 (r = 0.55-0.84, all ps generalized anxiety disorder diagnosis established by diagnostic interview. The somatic subscale in particular may require revision to improve predictive validity. Revision may also be necessary given changes in required somatic symptoms for generalized anxiety disorder diagnostic criteria in more recent versions of the Diagnostic and Statistical Manual of Mental Disorders (i.e. although major changes occurred from Diagnostic and Statistical Manual of Mental Disorders-III-R to Diagnostic and Statistical Manual of Mental Disorders-IV, changes in Diagnostic and Statistical Manual of Mental Disorders-5 were minimal) and the possibility of changes in the upcoming 11th revision of the International Classification of Diseases.

    Chevy, F.; Salomon, C.

    2016-10-01

    The strongly interacting Bose gas is one of the most fundamental paradigms of quantum many-body physics and the subject of many experimental and theoretical investigations. We review recent progress on strongly correlated Bose gases, starting with a description of beyond mean-field corrections. We show that the Efimov effect leads to non universal phenomena and to a metastability of the low temperature Bose gas through three-body recombination to deeply bound molecular states. We outline differences and similarities with ultracold Fermi gases, discuss recent experiments on the unitary Bose gas, and finally present a few perspectives for future research.

  10. Abortion: Strong's counterexamples fail

    2009-01-01

    This paper shows that the counterexamples proposed by Strong in 2008 in the Journal of Medical Ethics to Marquis's argument against abortion fail. Strong's basic idea is that there are cases--for example, terminally ill patients--where killing an adult human being is prima facie seriously morally......'s scenarios have some valuable future or admitted that killing them is not seriously morally wrong. Finally, if "valuable future" is interpreted as referring to objective standards, one ends up with implausible and unpalatable moral claims....

    2013-08-01

    Full Text Available Strongly interacting gases of ultracold fermions have become an amazingly rich test-bed for many-body theories of fermionic matter. Here we present our recent experiments on these systems. Firstly, we discuss high-precision measurements on the thermodynamics of a strongly interacting Fermi gas across the superfluid transition. The onset of superfluidity is directly observed in the compressibility, the chemical potential, the entropy, and the heat capacity. Our measurements provide benchmarks for current many-body theories on strongly interacting fermions. Secondly, we have studied the evolution of fermion pairing from three to two dimensions in these gases, relating to the physics of layered superconductors. In the presence of p-wave interactions, Fermi gases are predicted to display toplogical superfluidity carrying Majorana edge states. Two possible avenues in this direction are discussed, our creation and direct observation of spin-orbit coupling in Fermi gases and the creation of fermionic molecules of 23Na 40K that will feature strong dipolar interactions in their absolute ground state.

  2. A quantitative confidence signal detection model: 1. Fitting psychometric functions.

    Science.gov (United States)

    Yi, Yongwoo; Merfeld, Daniel M

    2016-04-01

    Perceptual thresholds are commonly assayed in the laboratory and clinic. When precision and accuracy are required, thresholds are quantified by fitting a psychometric function to forced-choice data. The primary shortcoming of this approach is that it typically requires 100 trials or more to yield accurate (i.e., small bias) and precise (i.e., small variance) psychometric parameter estimates. We show that confidence probability judgments combined with a model of confidence can yield psychometric parameter estimates that are markedly more precise and/or markedly more efficient than conventional methods. Specifically, both human data and simulations show that including confidence probability judgments for just 20 trials can yield psychometric parameter estimates that match the precision of those obtained from 100 trials using conventional analyses. Such an efficiency advantage would be especially beneficial for tasks (e.g., taste, smell, and vestibular assays) that require more than a few seconds for each trial, but this potential benefit could accrue for many other tasks.

  6. On the Psychometric Study of Human Life History Strategies.

    Science.gov (United States)

    Richardson, George B; Sanning, Blair K; Lai, Mark H C; Copping, Lee T; Hardesty, Patrick H; Kruger, Daniel J

    2017-01-01

    This article attends to recent discussions of validity in psychometric research on human life history strategy (LHS), provides a constructive critique of the extant literature, and describes strategies for improving construct validity. To place the psychometric study of human LHS on more solid ground, our review indicates that researchers should (a) use approaches to psychometric modeling that are consistent with their philosophies of measurement, (b) confirm the dimensionality of life history indicators, and (c) establish measurement invariance for at least a subset of indicators. Because we see confirming the dimensionality of life history indicators as the next step toward placing the psychometrics of human LHS on more solid ground, we use nationally representative data and structural equation modeling to test the structure of middle adult life history indicators. We found statistically independent mating competition and Super-K dimensions and the effects of parental harshness and childhood unpredictability on Super-K were consistent with past research. However, childhood socioeconomic status had a moderate positive effect on mating competition and no effect on Super-K, while unpredictability did not predict mating competition. We conclude that human LHS is more complex than previously suggested-there does not seem to be a single dimension of human LHS among Western adults and the effects of environmental components seem to vary between mating competition and Super-K.

    2013-05-01

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

    Recent national surveys in Brazil have demonstrated a decrease in the consumption of traditional food and a parallel increase in the consumption of ultra-processed food, which has contributed to a rise in obesity prevalence in all age groups. Environmental factors, especially familial factors, have a strong influence on the food intake of preschool children, and this has led to the development of psychometric scales to measure parents' feeding practices. The aim of this study was to test the validity of a translated and adapted Comprehensive Feeding Practices Questionnaire in a sample of Brazilian preschool-aged children enrolled in private schools. A transcultural adaptation process was performed in order to develop a modified questionnaire (43 items). After piloting, the questionnaire was sent to parents, along with additional questions about family characteristics. Test-retest reliability was assessed in one of the schools. Factor analysis with oblique rotation was performed. Internal reliability was tested using Cronbach's alpha and correlations between factors, discriminant validity using marker variables of child's food intake, and convergent validity via correlations with parental perceptions of perceived responsibility for feeding and concern about the child's weight were also performed. The final sample consisted of 402 preschool children. Factor analysis resulted in a final questionnaire of 43 items distributed over 6 factors. Cronbach alpha values were adequate (0.74 to 0.88), between-factor correlations were low, and discriminant validity and convergent validity were acceptable. The modified CFPQ demonstrated significant internal reliability in this urban Brazilian sample. Scale validation within different cultures is essential for a more comprehensive understanding of parental feeding practices for preschoolers.

    Discourse comprehension is a hallmark of human social behaviour and refers to the act of interpreting a written or spoken message by constructing mental representations that integrate incoming language with prior knowledge and experience. Here, we report a human lesion study (n = 145) that investigates the neural mechanisms underlying discourse comprehension (measured by the Discourse Comprehension Test) and systematically examine its relation to a broad range of psychological factors, including psychometric intelligence (measured by the Wechsler Adult Intelligence Scale), emotional intelligence (measured by the Mayer, Salovey, Caruso Emotional Intelligence Test), and personality traits (measured by the Neuroticism-Extraversion-Openness Personality Inventory). Scores obtained from these factors were submitted to voxel-based lesion-symptom mapping to elucidate their neural substrates. Stepwise regression analyses revealed that working memory and extraversion reliably predict individual differences in discourse comprehension: higher working memory scores and lower extraversion levels predict better discourse comprehension performance. Lesion mapping results indicated that these convergent variables depend on a shared network of frontal and parietal regions, including white matter association tracts that bind these areas into a coordinated system. The observed findings motivate an integrative framework for understanding the neural foundations of discourse comprehension, suggesting that core elements of discourse processing emerge from a distributed network of brain regions that support specific competencies for executive and social function.

Knowing the basic knowledge and grasping the test - taking tactics are key factors of good reading comprehension. In this thesis, I will dwell on nine commonly used tactics for reading comprehension. This will help you to deal with the problems with reading comprehension efficiently.

  19. Strong Field Spherical Dynamos

    CERN Document Server

    Dormy, Emmanuel

    2014-01-01

    Numerical models of the geodynamo are usually classified in two categories: those denominated dipolar modes, observed when the inertial term is small enough, and multipolar fluctuating dynamos, for stronger forcing. I show that a third dynamo branch corresponding to a dominant force balance between the Coriolis force and the Lorentz force can be produced numerically. This force balance is usually referred to as the strong field limit. This solution co-exists with the often described viscous branch. Direct numerical simulations exhibit a transition from a weak-field dynamo branch, in which viscous effects set the dominant length scale, and the strong field branch in which viscous and inertial effects are largely negligible. These results indicate that a distinguished limit needs to be sought to produce numerical models relevant to the geodynamo and that the usual approach of minimizing the magnetic Prandtl number (ratio of the fluid kinematic viscosity to its magnetic diffusivity) at a given Ekman number is mi...

  3. Strong Coupling and Classicalization

    CERN Document Server

    Dvali, Gia

    2016-01-01

    Classicalization is a phenomenon in which a theory prevents itself from entering into a strong-coupling regime, by redistributing the energy among many weakly-interacting soft quanta. In this way, the scattering process of some initial hard quanta splits into a large number of soft elementary processes. In short, the theory trades the strong coupling for a high-multiplicity of quanta. At very high energies, the outcome of such a scattering experiment is a production of soft states of high occupation number that are approximately classical. It is evident that black hole creation in particle collision at super-Planckian energies is a result of classicalization, but there is no a priory reason why this phenomenon must be limited to gravity. If the hierarchy problem is solved by classicalization, the LHC has a chance of detecting a tower of new resonances. The lowest-lying resonances must appear right at the strong coupling scale in form of short-lived elementary particles. The heavier members of the tower must b...

  4. On the psychometric properties of the aggressiveness-IAT for children and adolescents.

    In research on aggression, implicit association tests (IATs) have been constructed to elucidate automatic processes involved in aggressiveness. Despite an increasing number of applications of the "Aggressiveness-IAT" in basic and applied research, the psychometric properties of this method for measuring an automatic aggressive self-concept have not been comprehensively investigated. Although the Aggressiveness-IAT has been used both as a cross-situationally consistent trait measure and as a measure to indicate situational changes, prior studies have not tested to what extent it reliably captures a stable trait vs. an occasion-specific aggressive self-concept. The present research scrutinizes the psychometric properties of the Aggressiveness-IAT by addressing two issues. First, we tested the reliability, consistency, and occasion specificity of the Aggressiveness-IAT in a longitudinal panel study with four waves and 574 Austrian school children/adolescents by applying latent-state trait (LST) theory. Second, we validated latent trait scores of the IAT vis-à-vis other measures either clearly related to aggression or not. Results demonstrate that 20-30% of the variance in children's and adolescents' IAT scores is situation-unspecific (i.e., "stable"), whereas 36-50% are situation-specific. Regarding its construct validity, the Aggressiveness-IAT is correlated with explicit measures of aggression and related constructs, but it is not associated with discriminant variables (e.g., school achievement). Implications for using the Aggressiveness-IAT are discussed in the light of these findings. Aggr. Behav. 41:84-95 2015. © 2014 Wiley Periodicals, Inc.

    To develop and validate a concise, parent-completed Brief Intellectual Disability Scale (BIDS) for children in low-disability resource and high-disability care burden countries. In this prospective cross-sectional study of 124 children recruited from a facility for intellectual disability (ID), the newly developed BIDS as the measure for validation as well as for the gold standard and convergent and divergent validities was administered by independent raters. Tests for diagnostic accuracy, reproducibility, and validity were conducted at the item and scale levels. The BIDS scores of ≥5 (sensitivity [Sn] = 71.43%, specificity [Sp] = 80.95%) and ≥11 (Sn = 4.29%, Sp = 100%), with area under the curve of 0.79, are suggested, respectively, for screening and diagnostic use in Indian populations. The inter-rater reliability (intra-class correlation coefficient [ICC] = 0.96) and test-retest reliability at 4 weeks (ICC = 0.95) for BIDS are strong. Besides the adequate face and content validities, BIDS demonstrates good internal consistency (Cronbach α = 0.80) and item-total correlation. There is moderate convergent validity with Binet-Kamat Test of Intelligence or Gesell's Developmental Schedule (r = -0.66, P = 0.001) as well as with adaptive behavior measure of Vineland Social Maturity Scale (r =-0.52, P = 0.001) and low divergent validity with the subscales of Attention Deficit Disorder with Hyperactivity: Comprehensive Teacher Rating Scale ( r = -0.11, P = 0.7; r = 0.18, P = 0.5; r = 0.13, P = 0.6; r = 0.08, P = 0.7). An exploratory factor analysis demonstrated a three-factor structure, explaining 60% of variance. The BIDS shows promise as a psychometrically adequate, yet brief measure for identifying ID in countries with low disability care resources and high disability-related burden.

    Since no Italian validated instrument focuses specifically on the measurement of pathological gambling in very young people, with this study, we aim to adapt an international instrument (SOGS-RA) and assess its psychometric properties in a sample (n = 14.910) of young Italian students aged between 15 and 19 years. Cross-cultural adaptation of the instrument was performed through translation, synthesis of translation, back-translation, expert committee review, and pre-testing. The kappa statistic for test-retest concordance ranged from 0.53 to 0.80. Internal validity was assessed by the MCA that identified one principal component with eigenvalue equal to 3,875: the Divgi index and very simple structure analysis also pointed out one common factor, so uni-dimensionality of the SOGS-RA was accepted. Moreover the SOGS-RA was found to have acceptable internal consistency (α = 0.780). Cronbach's alpha was also assessed separately among males and females (respectively 0.786 and 0.707). The SOGS-RA was assessed in relation to gambling frequency, alcohol and drug use: Chi squared test revealed a strong association both for males and females with gambling frequency (p value ≤ 0.0001), frequent use of illicit drugs (for each drug p value ≤ 0.0001) and having had 3 or more occasions of binge drinking in the last month (p value ≤ 0.0001). At the end we can say that, the results of our study suggest that the SOGS-RA screen may be useful to assess at-risk or problem gambling for both genders in comprehensive youth surveys.

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

    Objective This study developed and examined the psychometric properties of a newly formed measure designed to assess professor/instructor bullying, as well as teacher bullying occurring prior to college. Additionally, prevalence of instructor bullying and characteristics related to victims of instructor bullying were examined. Participants Participants were 337 college students recruited in 2012 from a northeastern university. Methods An online questionnaire was administered to college students. A split-half, cross-validation approach was employed for measurement development. Results The measure demonstrated strong criterion validity and internal consistency. Approximately half of students reported witnessing professor/instructor bullying and 18% reported being bullied by a professor/instructor. Report of teacher bullying occurring prior to college was related to professor/instructor bullying in college, and sex was a moderating variable. Conclusion College students perceive instructor bullying as occurring but may not know how to properly address it. Prevention efforts should be made by university administrators, faculty and staff.

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

    Despite the expansion of early intervention approaches for young children with ASD, investigators have struggled to identify measures capable of assessing social communication change in response to these interventions. Addressing recent calls for efficient, sensitive, and reliable social communication measures, the current paper outlines the refinement and validation of the Social Communication Checklist (SCC). We discuss two small studies exploring the psychometric properties of the SCC and the SCC-R (revised Social Communication Checklist), including sensitivity to change, inter-rater reliability, and test-retest reliability, in two samples of children with ASD and one sample of typically-developing children. Results indicate this measure is reliable, sensitive to change after a brief social communication intervention, and strongly related to well-established measures of social communicative functioning.

    The present study aimed to test the psychometric properties of the Polish version of the managing the emotions of others scale (MEOS). MEOS consists of six dimensions: mood enhancing (Enhance), mood worsening (Worsen), concealing emotions from others (Conceal), use of inauthentic displays for self-serving purposes (Inauthentic), poor emotion skills (Poor skills), and use of diversion to enhance another's mood (Divert). The results showed that among MEOS dimensions, Enhance was the most strongly related to performance-based emotional intelligence. Among the Dark Triad, Narcissism was related to the greatest number of MEOS subscales-all except Poor skills. The results indicated that the MEOS has a similar factor structure, reliability, and pattern of correlations with personality and emotional intelligence in Poland as in previous studies.

    This investigation aimed to develop and collect psychometric data for two tests assessing listening comprehension of Portuguese students in primary school: the Test of Listening Comprehension of Narrative Texts (TLC-n) and the Test of Listening Comprehension of Expository Texts (TLC-e). Two studies were conducted. The purpose of study 1 was to construct four test forms for each of the two tests to assess first, second, third and fourth grade students of the primary school. The TLC-n was administered to 1042 students, and the TLC-e was administered to 848 students. The purpose of study 2 was to test the psychometric properties of new items for the TLC-n form for fourth graders, given that the results in study 1 indicated a severe lack of difficult items. The participants were 260 fourth graders. The data were analysed using the Rasch model. Thirty items were selected for each test form. The results provided support for the model assumptions: Unidimensionality and local independence of the items. The reliability coefficients were higher than .70 for all test forms. The TLC-n and the TLC-e present good psychometric properties and represent an important contribution to the learning disabilities assessment field.

    A 1997 study evaluated the quantitative, publicly available, and regularly reported data continuously collected by Oxfam to determine whether there have been changes in the diversity of employees over the past 3 years, whether the data collection met the needs of managers trying to implement the gender policy, and what strategies and recommendations could be adopted. It was found that, until recently, Oxfam only collected data about contracted staff in the UK, including only senior staff in country offices. In addition, Oxfam has not collected publicly available information about the most senior management positions. The analysis based on the incomplete information available indicated that the UK-contracted work force contains a majority of women, but men remain three grades higher than most women and women occupy fewer and fewer positions as the management ladder climbs. The gender-mapping report recommended that Oxfam 1) collect data on all employees; 2) commission research to identify and analyze key factors that prohibit women from advancing in management; and 3) make a commitment to ensure that the gains women have made continue. In related work in the East and Central Africa region, the recruitment of a human resources officer will facilitate the collection of comprehensive human resources data as a basis for future decision-making. Problems faced include the fact that women caring for dependents will have less opportunity to take advantage of the employment opportunities offered by regionalization and that mobility will be hampered by restrictions on visas and work permits.

    Strongly correlated materials are profoundly affected by the repulsive electron-electron interaction. This stands in contrast to many commonly used materials such as silicon and aluminum, whose properties are comparatively unaffected by the Coulomb repulsion. Correlated materials often have remarkable properties and transitions between distinct, competing phases with dramatically different electronic and magnetic orders. These rich phenomena are fascinating from the basic science perspective and offer possibilities for technological applications. This article looks at these materials through the lens of research performed at Rice University. Topics examined include: Quantum phase transitions and quantum criticality in "heavy fermion" materials and the iron pnictide high temperature superconductors; computational ab initio methods to examine strongly correlated materials and their interface with analytical theory techniques; layered dichalcogenides as example correlated materials with rich phases (charge density waves, superconductivity, hard ferromagnetism) that may be tuned by composition, pressure, and magnetic field; and nanostructure methods applied to the correlated oxides VO₂ and Fe₃O₄, where metal-insulator transitions can be manipulated by doping at the nanoscale or driving the system out of equilibrium. We conclude with a discussion of the exciting prospects for this class of materials.

  16. Strong Coupling Holography

    2009-01-01

    We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4+d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this effect for orbifold planes, as well as for the solitonic branes and string theoretic D-branes. In all cases the emergence of a 4D strong coupling scale from bulk holography is a persistent phenomenon. The effect turns out to be insensitive even to such extreme deformations of the brane action that seemingly shield 4D theory from the bulk gravity effects. A well understood example of such deformation is given by large 4D Einstein term in the 3-brane action, which is known to suppress the strength of 5D gravity at short distances and change the 5D Newton's law into the four-dimensional one. Nevertheless, we observe that the ...

    The determinants of the health-related quality of life of women with polycystic ovary syndrome are not fully understood. The aim of this study was to develop a comprehensive instrument to assess the health-related quality of life of Iranian women with PCOS and to assess its psychometric properties. We used a mixed-method, sequential, exploratory design including both qualitative [in-depth interview to define the components of health-related quality of life questionnaire (PCOSQ)] and quantitative approaches (to assess the psychometric properties of PCOSQ). A preliminary questionnaire was developed including 147 items which emerged from the qualitative phase of the study. Considering the optimum cutoff points for content validity ratio (CVR), content validity index (CVI), and impact score, items of the preliminary questionnaire were reduced from 147 to 88 items. Finally, by excluding highly correlated items using the exploratory factor analysis, a 50-item questionnaire was obtained. The Kaiser criteria (eigenvalues >1) and Scree plot tests demonstrated that six factors were optimum with an estimated 47.3 % of variance. Assessment of the psychometric properties of the questionnaire demonstrated a mean CVI = 0.92, CVR = 0.91, Cronbach's alpha for whole questionnaire = 0.88 (0.61-0.88 for subscales), Spearman's correlation coefficients of test-retest = 0.75, and the intra-class correlation coefficient for the PCOS questionnaire subscales ranging from 0.57 to 0.88. Eventually the final questionnaire included 50 items in six domains, 'psychosocial and emotional,' 'fertility,' 'sexual function,' 'obesity and menstrual disorders,' 'hirsutism,' and 'coping' and rated on a 5-point Likert scale. The PCOSQ-50 is a valid and reliable instrument for the assessment of quality of life of women with PCOS, capable of assessing some obscure aspects overlooked by previous HRQL questionnaires.

    The aim of this study was to assess the psychometric properties of the EQ-5D-3 L, the SF-12 v2 and its preference based derivative the SF-6D, and the St Georges Respiratory Questionnaire (SGRQ), in patients diagnosed with Acute Respiratory Distress Syndrome (ARDS). Data from the Oscillation in ARDS (OSCAR) randomised unblinded clinical trial of 795 patients diagnosed with ARDS provided the foundation of this secondary psychometric analysis. The three source patient reported outcome measures (PROMs) (EQ-5D-3 L, SF-12 and SGRQ) were collected at both 6 and 12 months post randomisation. All measures were tested for acceptability, reliability, internal consistency, validity and responsiveness. Data from responders at 6 months was used to test for acceptability, reliability, known groups validity and internal responsiveness. Data from patients who responded at both 6 and 12 months was used to test for convergent validity and external responsiveness. Rates of response at both 6 and 12 months post randomisation were 89.88 % for the EQ-5D-3 L, 77.38 % for the SF-6D, 71.43 % for both the physical and mental components of the SF-12 and 38.10 % for the SGRQ. All measures had a Cronbach's Alpha statistic higher than 0.7. For known group's validity, there was no difference in mean summary or utility scores between known groups for all PROMs with minimal effect sizes. All three source measures showed strong convergent and discriminant validity. There was consistent evidence that the SF-6D is an empirically valid and efficient alternative to the EQ-5D-3 L. The EQ-5D-3 L and SGRQ were more responsive compared to the SF-12 and SF-6D with the EQ-5D-3 L generating greater effect sizes than the SGRQ. The PROMs explored in this study displayed varying psychometric properties in the context of ARDS. Further research should focus on shortening the SGRQ whilst still maintaining its psychometric properties and mapping between the SGRQ and preference-based measures for future application

    To determine the psychometric properties and theoretical grounding of instruments that evaluate self-care behaviour or barriers in people with type 2 diabetes. There are many instruments designed to evaluate self-care behaviour or barriers in this population, but knowledge about their psychometric validation processes is lacking. Systematic review. We conducted a search for psychometric or validation studies published between January 1990-December 2012. We carried out searches in Pubmed, CINAHL, PsycINFO, ProQuolid, BibliPRO and Google SCHOLAR to identify instruments that evaluated self-care behaviours or barriers to diabetes self-care. We conducted a systematic review with the following inclusion criteria: Psychometric or clinimetric validation studies that included patients with type 2 diabetes (exclusively or partially) and which analysed self-care behaviour or barriers to self-care and proxies like self-efficacy or empowerment, from a multidimensional approach. Language: Spanish or English. Two authors independently assessed the quality of the studies and extracted data using Terwee's proposed criteria: psychometrics properties, dimensionality, theoretical ground and population used for validation through each included instrument. Sixteen instruments achieved the inclusion criteria for the review. We detected important methodological flaws in many of the selected instruments. Only the Self-management Profile for Type 2 Diabetes and Problem Areas in Diabetes Scale met half of Terwee's quality criteria. There are no instruments for identifying self-care behaviours or barriers elaborated with a strong validation process. Further research should be carried out to provide patients, clinicians and researchers with valid and reliable instruments that are methodologically solid and theoretically grounded. © 2013 John Wiley & Sons Ltd.

    Models including an energy transfer from CDM to DE are widely considered in the literature, namely to allow DE a significant high-z density. Strongly Coupled cosmologies assume a much larger coupling between DE and CDM, together with the presence of an uncoupled warm DM component, as the role of CDM is mostly restricted to radiative eras. This allows us to preserve small scale fluctuations even if the warm particle, possibly a sterile neutrino, is quite light, O(100 eV). Linear theory and numerical simulations show that these cosmologies agree with LCDM on supergalactic scales; e.g., CMB spectra are substantially identical. Simultaneously, simulations show that they significantly ease problems related to the properties of MW satellites and cores in dwarfs. SC cosmologies also open new perspectives on early black hole formation, and possibly lead towards unificating DE and inflationary scalar fields.

  2. On Strong Cosmic Censorship

    Isenberg, James

    2015-01-01

    For almost half of the one hundred year history of Einstein's theory of general relativity, Strong Cosmic Censorship has been one of its most intriguing conjectures. The SCC conjecture addresses the issue of the nature of the singularities found in most solutions of Einstein's gravitational field equations: Are such singularities generically characterized by unbounded curvature? Is the existence of a Cauchy horizon (and the accompanying extensions into spacetime regions in which determinism fails) an unstable feature of solutions of Einstein's equations? In this short review article, after briefly commenting on the history of the SCC conjecture, we survey some of the progress made in research directed either toward supporting SCC or toward uncovering some of its weaknesses. We focus in particular on model versions of SCC which have been proven for restricted families of spacetimes (e.g., the Gowdy spacetimes), and the role played by the generic presence of Asymptotically Velocity Term Dominated behavior in th...

    2004-10-01

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

    This study aimed to evaluate the psychometric properties of the General Health Questionnaire (GHQ-30) given conflicting findings in the literature. A cross-sectional, nonexperimental research was used with a convenience sample of 271 American female health care professionals. Data were collected by using self-reported questionnaires. A series of exploratory factor analyses (EFAs), confirmatory factor analyses (CFAs), and structural equation modeling (SEM) were performed to examine underlying dimensions of the GHQ-30. Results from EFAs and CFAs revealed the three-factor composition (positive affect, anxiety, and depressed mood). All factor loadings were statistically significant, and one pair of error variance was allowed to be correlated. All factors contained questionnaire items with acceptable face validity and demonstrated good internal consistency reliability. Results from SEM further confirmed underlying constructs of the scale. To our knowledge, this is the first study that extensively tested the psychometric properties of the GHQ-30, taking both statistical and substantive issues into consideration.

    QuickEval is a web application for carrying out psychometric scaling experiments. It offers the possibility of running controlled experiments in a laboratory, or large scale experiment over the web for people all over the world. It is a unique one of a kind web application, and it is a software needed in the image quality field. It is also, to the best of knowledge, the first software that supports the three most common scaling methods; paired comparison, rank order, and category judgement. It is also the first software to support rank order. Hopefully, a side effect of this newly created software is that it will lower the threshold to perform psychometric experiments, improve the quality of the experiments being carried out, make it easier to reproduce experiments, and increase research on image quality both in academia and industry. The web application is available at www.colourlab.no/quickeval.

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

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

    Full Text Available After many decades of romantic relationship research, there is a new focus on a multidimensional model of love. This empirical study examines the multidimensionality and psychometrics of Passionate and Companionate love, based on an extensive study of 413 participants using Multidimensional Love Scale (MLS. A new statistical approach employed in this study explores the typology and structure of love. The statistical approach included the combination of Two-Step Cluster Analysis of cases and Principle Component Analysis of dimensions while using centered variable scores. The results reveal a typology of love based on its multidimensional structure. Further analysis revealed two main types of love: Passionate and Companionate, both containing several factors allowing for interpretation of their multidimensional structures. The MLS subscales and detailed psychometric analysis measuring specific love dimensions are incorporated to allow further research in other studies.

    The purpose of this study was to test the psychometric properties of the Nursing Teamwork Survey-Icelandic (NTS-Icelandic), which was translated from US English to Icelandic. The Nursing Teamwork Survey, with 33 items, measures overall teamwork and five factors of teamwork: trust, team orientation, backup, shared mental models, and team leadership. The psychometric testing of the NTS-Icelandic was carried out on data from a pilot study and a national study. The sample for a pilot study included 123 nursing staff from five units, and the sample for a national study included 925 nursing staff from 27 inpatient units. The overall test-retest intraclass correlation coefficient in the pilot study was 0.693 (lower bound = 0.498, upper bound = 0.821) (p teamwork. The NTS-Icelandic tested valid and reliable in this study. Study findings support further use of the Nursing Teamwork Survey internationally.

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

    Type 2 diabetes mellitus (T2DM) self-management among Hispanic adults occurs in a family context. Self-efficacy (SE) affects T2DM self-management behaviors; however, no instruments are available to measure family diabetes self-efficacy. The study's purpose was to test the psychometric properties of the Family Self-Efficacy for Diabetes Scale (FSE). Family members (n = 113) of adults with T2DM participated. Psychometric analysis included internal consistency reliability and concurrent and construct validity. Internal consistency reliability was .86. Items loaded on 2 factors, Family SE for Supporting Healthy Behaviors and Family SE for Supporting General Health, accounting for 71% of the variance. FSE correlated significantly with 3 diabetes-related instruments. The FSE is a reliable and valid instrument. Further testing is needed in diverse populations and geographic areas.

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

    Paula Inez Cunha Gomide

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

    Orthorexia nervosa has recently been defined as excessive preoccupation with healthy eating, causing significant nutritional deficiencies and social and personal impairments. The ORTO-15 is the most widely used instrument to evaluate orthorexia nervosa, although previous studies obtained inconsistent results about its psychometric properties, and there are no data on the Spanish version. Thus, the main objective of the present study was to analyze the psychometric properties of the Spanish adaptation of the ORTO-15. In order to cross-validate the results, two independent samples were used (Sample 1: n = 807, 74.1% women; Sample 2: n = 242, 63.2% women). The results did not support the original recoding and reversal of the items; thus, the original scores were maintained. The analysis of the internal structure showed that the best interpretable solution was unidimensional, and due to low loadings, four items were removed. The internal consistency (α = .74) and temporal stability (r = .92; p orthorexia nervosa.

    Given a directed graph G, an edge is a strong bridge if its removal increases the number of strongly connected components of G. Similarly, we say that a vertex is a strong articulation point if its removal increases the number of strongly connected components of G. In this paper, we present linear-time algorithms for computing all the strong bridges and all the strong articulation points of directed graphs, solving an open problem posed in [2].

    2009-09-01

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

Comparable instruments were also developed for children and adolescents (the Health of the Nation Outcome Scales for Children and Adolescents and older people (the Health of the Nation Outcome Scales 65+. All three are being widely used as outcome measures in the United Kingdom, Australia and New Zealand. There is, however, no comprehensive review of these instruments. This paper fills this gap by reviewing the psychometric properties of each. Method Articles and reports relating to the instruments were retrieved, and their findings synthesised to assess the instruments' validity (content, construct, concurrent, predictive, reliability (test-retest, inter-rater, sensitivity to change, and feasibility/utility. Results Mostly, the instruments perform adequately or better on most dimensions, although some of their psychometric properties warrant closer examination. Conclusion Collectively, the Health of the Nation Outcome Scales family of measures can assess outcomes for different groups on a range of mental health-related constructs, and can be regarded as appropriate for routinely monitoring outcomes.

    The International Classification of Functioning, Disability and Health (ICF) conceptualizes the bio-psycho-social model of health and illness, but cannot be used as an assessment instrument in routine care. The objective of this study was to psychometrically test a self-report instrument for measuring activities and social participation (ICF-Mental-A&P) of psychotherapy patients. For the psychometric evaluation of the ICF-Mental-A&P, participants completed a questionnaire on symptoms, interpersonal problems and quality of life at admission and at discharge of in-patient treatment. A consecutive sample of 2256 patients diagnosed with at least one mental disorder was recruited from eight in-patient units in Germany. After item selection, the ICF-Mental-A&P contained 31 items comprising six subscales examined by confirmatory factor analysis. Subscales had acceptable internal consistency (α = 0.78-0.90) and test-retest correlations (r = 0.71-0.86). There were several expected correlations (r ≥ 0.6) between ICF-Mental-A&P scores and measures of symptoms and interpersonal problems. Findings suggest that the ICF-Mental-A&P is a comprehensive, reliable measure of activities and participation according to the ICF concept for patients with mental disorders. It may therefore be an important instrument in clinical practice and could help to determine and evaluate functioning-related and patient-focused treatment outcomes.

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

    The psychometric characteristics of multiple-choice questions (MCQ) changed when taking into account their anatomical sites and the presence of item-writing flaws (IWF). The aim is to understand the impact of the anatomical sites and the presence of IWF in the psychometric qualities of the MCQ. 800 Clinical Anatomy MCQ from eight examinations were classified as standard or flawed items and according to one of the eight anatomical sites. An item was classified as flawed if it violated at least one of the principles of item writing. The difficulty and discrimination indices of each item were obtained. 55.8 % of the MCQ were flawed items. The anatomical site of the items explained 6.2 and 3.2 % of the difficulty and discrimination parameters and the IWF explained 2.8 and 0.8 %, respectively. The impact of the IWF was heterogeneous, the Writing the Stem and Writing the Choices categories had a negative impact (higher difficulty and lower discrimination) while the other categories did not have any impact. The anatomical site effect was higher than IWF effect in the psychometric characteristics of the examination. When constructing MCQ, the focus should be in the topic/area of the items and only after in the presence of IWF.

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

    Psychometric sensory discrimination functions are usually modeled by cumulative Gaussian functions with just two parameters, their central tendency (μ) and their slope (1/σ). These correspond to Fechner's "constant" and "variable" errors, respectively. Fechner pointed out that even the constant error could vary over space and time and could masquerade as variable error. We wondered whether observers could deliberately introduce a constant error into their performance without loss of precision. In three-dot vernier and bisection tasks with the method of single stimuli, observers were instructed to favour one of the two responses when unsure of their answer. The slope of the resulting psychometric function was not significantly changed, despite a significant change in central tendency. Similar results were obtained when altered feedback was used to induce bias. We inferred that observers can adopt artificial response criteria without any significant increase in criterion fluctuation. These findings have implications for some studies that have measured perceptual "illusions" by shifts in the psychometric functions of sophisticated observers.

    2006-04-01

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

    2013-12-01

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

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions. Following ALEPH he tur...

    The specific enhancement of ultra-low-frequency (ULF) electromagnetic oscillations a few hours prior to the strong earthquakes, which was previously mentioned in the literature, motivated us to search for the distinctive features of the mechanical (foreshock) activity of the Earth's crust in the epicentral zones of the future earthquakes. Activation of the foreshocks three hours before the main shock is revealed, which is roughly similar to the enhancement of the specific electromagnetic ULF emission. It is hypothesized that the round-the-world seismic echo signals from the earthquakes, which form the peak of energy release 2 h 50 min before the main events, act as the triggers of the main shocks due to the cumulative action of the surface waves converging to the epicenter. It is established that the frequency of the fluctuations in the foreshock activity decreases at the final stages of the preparation of the main shocks, which probably testifies to the so-called mode softening at the approach of the failure point according to the catastrophe theory.

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

    Full Text Available ABSTRACT BACKGROUND: Fatigue is a common complaint in cirrhotic patients and may be considered a debilitating symptom with negative impact on quality of life. Research on its etiology and treatment has been hampered by the lack of relevant and reproducible measures of fatigue. OBJECTIVE: To evaluate the psychometric properties of the Fatigue Severity Scale (FSS in cirrhotic patients and to correlate with depressive symptomatology and quality of life. METHODS: Cross-sectional study with a convenience sample of 106 cirrhotic patients, aged between 18 and 70 years, both genders, literate, pre and post liver transplantation in outpatient follow-up. Internal consistency, reproducibility, discriminant validity, criterion validity, construct validity, responsiveness criterion, depressive symptomatology and quality of life were evaluated through questionnaires between January and October 2015. RESULTS: The mean age was 54.75±9.9 years, 65.1% male and 32.1% of the sample had cirrhosis due to hepatitis C virus. The mean FSS score was 4.74±1.64. Cronbach’s alpha was 0.93, and the Intraclass Correlation Coefficient was 0.905 (95% CI: 0.813-0.952. For discriminant validity, FSS differentiated scores from different groups (P=0.009 and presented a correlation with the Modified Fatigue Impact Scale (r=0.606, P=0.002. FSS correlated significantly and positively with depressive symptomatology and correlated negatively with the SF-36 domains for construct validity. For responsiveness, no significant changes were observed in the fatigue scores in the pre and post-liver transplantation periods (P=0.327. CONCLUSION: FSS showed good psychometric performance in the evaluation of fatigue in patients with cirrhosis. Fatigue presented a strong correlation with depressive symptomatology and quality of life.

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

    Humans imitate each other during social interaction. This imitative behavior streamlines social interaction and aids in learning to replicate actions. However, the effect of imitation on action comprehension is unclear. This study investigated whether vocal imitation of an unfamiliar accent improved spoken-language comprehension. Following a pretraining accent comprehension test, participants were assigned to one of six groups. The baseline group received no training, but participants in the other five groups listened to accented sentences, listened to and repeated accented sentences in their own accent, listened to and transcribed accented sentences, listened to and imitated accented sentences, or listened to and imitated accented sentences without being able to hear their own vocalizations. Posttraining measures showed that accent comprehension was most improved for participants who imitated the speaker's accent. These results show that imitation may aid in streamlining interaction by improving spoken-language comprehension under adverse listening conditions.

    The consideration of organisational aspects, such as shared goals and clear communication, within the health care team is important to ensure good quality care. In primary health care, the instrument Survey of Organizational Attributes for Primary Care (SOAPC) is available to measure organisational attributes of care. However, there is no instrument available for dental care. The aim of the present study was to investigate psychometric properties and test-retest reliability of the version of SOAPC adapted for dental care, namely the Survey of Organizational Attributes in Dental Care (SOADC). The SOADC consists of 21 items in the following four subscales: communication; decision making; stress/chaos; and history of change. Convergent construct validity was measured using the job satisfaction scale. A total of 287 dental-care practices were asked to participate in the validation study. Psychometric properties and test-retest reliability were observed. A total of 43 dental-care practices responded to the survey. At baseline, 178 dental-care staff completed the questionnaire, and 4 weeks later 138 did so. Internal consistency, measured by Cronbach's alpha, was 0.718 or higher in the subscales. The test-retest reliability for each subscale and the overall SOADC score demonstrated good correlations over the 4-week test-retest interval, except for 'history of change'. A strong correlation with the aggregated job-satisfaction scale showed high convergent construct validity of SOADC. The consideration of organisational aspects from the perspective of dental-care teams is important for providing good quality of care. The SOADC is a reliable instrument with good psychometric properties and is suitable for the evaluation of organisational attributes in dental-care practices. © 2015 FDI World Dental Federation.

    Full Text Available The academic debate nowadays is focused on producing an applied science of learning, aiming to teach students how to learn and be strategic in their acquisition. The aim of the study is to identify and discuss the reading comprehension instruction approach applied in the Albanian system of education. Findings from 10 classes of Albanian language and literature with students of third grade were directly observed and analyzed, in order to gather evidence based on indicators and instruments that assess the way of reading comprehension. Findings were categorized according to strategy use; the frequency of their application in different classes was counted and represented in percentages. In this paper we will try to respond to questions like: What are students' main barriers of comprehending? Does the instructional approach respond to students’ needs and level of comprehension? Are teachers prepared to teach comprehension strategies? Furthermore, examples of procedures on how to deliver instruction of comprehension strategies in natural contexts will be represented. Results from teacher practices during lessons of reading comprehension confirmed that teachers use limited teaching strategies to deliver lessons. They mainly use strategies to test comprehension; while the approach of teaching students to read independently and strategically is an unknown practice.

    The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Symptom Validity (Fake Bad Scale [FBS]) Scale is widely used to assist in determining noncredible symptom reporting, despite a paucity of detailed research regarding its itemmetric characteristics. Originally designed for use in civil litigation, the FBS is often used in a variety of clinical settings. The present study explored its fundamental psychometric characteristics in a sample of 303 patients who were consecutively referred for a comprehensive examination in a Veterans Affairs (VA) neuropsychology clinic. FBS internal consistency (reliability) was .77. Its underlying factor structure consisted of three unitary dimensions (Tiredness/Distractibility, Stomach/Head Discomfort, and Claimed Virtue of Self/Others) accounting for 28.5% of the total variance. The FBS's internal structure showed factoral discordance, as Claimed Virtue was negatively related to most of the FBS and to its somatic complaint components. Scores on this 12-item FBS component reflected a denial of socially undesirable attitudes and behaviors (Antisocial Practices Scale) that is commonly expressed by the 1,138 males in the MMPI-2 normative sample. These 12 items significantly reduced FBS reliability, introducing systematic error variance. In this VA neuropsychological referral setting, scores on the FBS have ambiguous meaning because of its structural discordance.

    The aim of this study is to examine the reliability and validity of the Turkish adaptations of the Positive Beliefs about Rumination Scale (PBRS) and the Negative Beliefs about Rumination Scale (NBRS) in clinical and non-clinical samples. While the non-clinical sample of the study consisted of 455 participants, the clinical sample was composed of 60 major depressive disorder (MDD), 30 panic disorder (PD) and 30 social anxiety disorder (SAD) cases. The results of the factor analyses confirm the construct validity and original factor structure of the scales. Findings obtained from internal consistency and test-retest analyses indicated good reliability for the scales. Supporting the convergent validity of the scales, the correlations between metacognitions about rumination and depressive symptoms, rumination, metacognitions about worry, pathological worry, and anxiety symptoms were found to be positive and significant in the non-clinical sample. Hierarchical regression analyses demonstrated that both scales have predictive validity for depressive symptoms after controlling for anxiety symptoms. As for extreme group comparisons, it supported the criterion-related validity of the scales. In discriminant clinical validity examinations, although both scales were able to differentiate MDD, PD, and SAD groups from healthy controls, they were unable to differentiate the depressive group from the other anxiety disorder groups. A comprehensive psychometric evaluation of the scales demonstrated that both PBRS and NBRS are reliable and valid assessment devices that can be used for research purposes both in clinical and non-clinical groups in Turkey.

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

    This study examined the psychometric properties of the Chinese version of the Personal Diabetes Questionnaire (C-PDQ). The PDQ was translated into Chinese using a forward and backward translation approach. After being reviewed by an expert panel, the C-PDQ was administered to a convenience sample of 346 adults with Type 2 diabetes. The Chinese version of the Summary of Diabetes Self-Care Activities (C-SDSCA) was also administered. The results of the exploratory factor analysis revealed a one-factor structure for the Diet Knowledge, Decision-Making, and Eating Problems subscales and a two-factor structure for the barriers-related subscales. The criterion and convergent validity were supported by significant correlations of the subscales of the C-PDQ with the glycated hemoglobin values and the parallel subscales in the C-SDSCA, respectively. The C-PDQ subscales also showed acceptable internal consistency (α = .61-.89) and excellent test-retest reliability (intraclass correlation coefficients: .73-.96). The results provide preliminary support for the reliability and validity of the C-PDQ. This comprehensive, patient-centered instrument could be useful to identify the needs, concerns, and priorities of Chinese patients with type 2 diabetes. © The Author(s) 2016.

Given its symptoms and neurobiological features, attention-deficit hyperactivity disorder (ADHD should be susceptible to impairment in organization. A valid organization scale is imperative to assess and intervene individuals with ADHD. However, there is no validated organization scale in Japan. Referring to existing scales and clinical experience, the self-rating organization scale (SOS was developed and tested in terms of its psychometric properties with 1,017 adults and students including 47 adults with ADHD. Additionally, cutoffs for disorganization were set for clinical utility. Three factors (materials disorganization, temporal disorganization, and mess were extracted by factor analyses. The index for reliability and validity of the SOS was acceptable. The factor “mess” could reflect the unique aspect of the Japanese environment. Further study is needed to enhance the clinical utility of the SOS. Keywords: adult, attention-deficit hyperactivity disorder, organization, scale

    The New Multi-dimensional Depression Scale (NMDS) is one of the most comprehensive scales that measures depression symptoms in four domains, including emotional, cognitive, somatic, and interpersonal. This study aimed to evaluate the factor structure and psychometric properties of the NMDS in a group of Iranian inpatients with Major Depressive Disorder (MDD). At first, the scale was translated into Persian and used as part of a battery consisting of the Beck Depression Inventory-II (BDI-II), Oxford Happiness Inventory (OHI), Beck Anxiety Inventory (BAI), and Short Form Health Survey (SF-36). The battery was administered to 271 inpatients with MDD (90 men and 181 women) aged from 18 to 60 who had been referred to psychiatric hospitals in Tehran, Iran. Confirmatory factor analysis of the Persian version of the NMDS upheld its original four-factor structure. Moreover, the results showed its good internal consistency (Cronbach's alpha coefficient ranging from 0.70 for the emotional subscale to 0.83 for the interpersonal subscale). In addition, the NMDS scores were correlated with other constructs in empirically and theoretically expected ways, which provides evidence for the convergent (positive significant relationships with anxiety and cognitive and somatic-affective symptoms of depression) and divergent (negative significant relationships with happiness and mental health and physical health) validity of the scale. These findings supported the Persian version of the NMDS as a reliable and valid measure for the assessment of depression symptoms in patients with MDD.

    Full Text Available Orientation: Corporate survival mechanisms, like mergers, downsizing, restructuring and outsourcing, contribute to unemployment levels amongst adults. Psychological maturity seems to influence the quality of the career decisions that people make in these difficult circumstances. However, we do not know what their behavioural strengths are.Research objectives: The objective of this study was to investigate the psychometric relationship between career thinking (negative and positive career thoughts and salutogenic functioning (locus of control and sense of coherence amongst unemployed adults.Motivation for study: Career decision research has consistently surveyed students to understand career indecision. Adults are not a homogenous group. Therefore, this trend may not reflect throughout the larger adult population. For this reason, the researchers conducted exploratory research into the nature of career indecision amongst non-student adults.Research design, approach and method: The researchers used a quantitative design that included a four-instrument survey on a purposive sample of 225 Canadian unemployed and non-student adults who had not decided on a career. They calculated correlations and regressions.Main findings: The researchers reported significant relationships between the four constructs. They found that a sense of coherence predicted career thinking.Contribution/value-add: A sense of coherence, which includes comprehension, meaningfulness and manageability, acts as a facilitator of effective career thinking.Practical/managerial implications: During career assessment and guidance, the role of sense of coherence as a strength factor will indicate the person’s readiness to make important career decisions.

  15. Interruptions disrupt reading comprehension.

    Previous research suggests that being interrupted while reading a text does not disrupt the later recognition or recall of information from that text. This research is used as support for Ericsson and Kintsch's (1995) long-term working memory (LT-WM) theory, which posits that disruptions while reading (e.g., interruptions) do not impair subsequent text comprehension. However, to fully comprehend a text, individuals may need to do more than recognize or recall information that has been presented in the text at a later time. Reading comprehension often requires individuals to connect and synthesize information across a text (e.g., successfully identifying complex topics such as themes and tones) and not just make a familiarity-based decision (i.e., recognition). The goal for this study was to determine whether interruptions while reading disrupt reading comprehension when the questions assessing comprehension require participants to connect and synthesize information across the passage. In Experiment 1, interruptions disrupted reading comprehension. In Experiment 2, interruptions disrupted reading comprehension but not recognition of information from the text. In Experiment 3, the addition of a 15-s time-out prior to the interruption successfully removed these negative effects. These data suggest that the time it takes to process the information needed to successfully comprehend text when reading is greater than that required for recognition. Any interference (e.g., an interruption) that occurs during the comprehension process may disrupt reading comprehension. This evidence supports the need for transient activation of information in working memory for successful text comprehension and does not support LT-WM theory. (c) 2015 APA, all rights reserved).

  16. Quotient-Comprehension Chains

    Directory of Open Access Journals (Sweden)

    Kenta Cho

    2015-11-01

    Full Text Available Quotients and comprehension are fundamental mathematical constructions that can be described via adjunctions in categorical logic. This paper reveals that quotients and comprehension are related to measurement, not only in quantum logic, but also in probabilistic and classical logic. This relation is presented by a long series of examples, some of them easy, and some also highly non-trivial (esp. for von Neumann algebras. We have not yet identified a unifying theory. Nevertheless, the paper contributes towards such a theory by introducing the new quotient-and-comprehension perspective on measurement instruments, and by describing the examples on which such a theory should be built.

Psychological research on risk perception has been dominated by the psychometric paradigm which has been fruitful in bringing up important issues in research. Yet, most of the conclusions reached in the paradigm are not sufficiently well based on empirical data and appropriate analyses. Results are presented here which show the prevalence of risk for energy attitudes, the importance of Tampering with Nature as a new risk dimension accounting for much of the perceived risk of nuclear waste, widely different levels but similar correlational structures of risk perception data for experts and the public, moderately strong correlations between perceived risk and trust (especially specific trust rather than general trust), and demand for risk mitigation being related most strongly to seriousness of consequences of a hazard, not the risk of an accident or the riskiness of the activity. Risk perception is related to conceptions of knowledge which stress the limits of science and different, New Age type, ways of knowing. Finally, interest emerged as an important predictor of demand for risk mitigation. A conceptualization of the risk perceiver, based on these results, is briefly discussed.

    Full Text Available This study attempts to shed light on the concept of assessment as an essential pedagogical practice for the improvement of the teaching-learning process. Particularly, it stresses the strategies and the techniques that should be used in assessing reading comprehension with reference to EFL classrooms. It describes the kinds of tasks that actually reveal students’ reading comprehension abilities and needs. Moreover, this paper aims to illustrate the types and the advantages of assessment for both teachers and learners. More importantly, this study tries to bring equitable evidence of how reading comprehension can be adequately assessed. The findings showed that assessment of reading comprehension is central to English language teaching as it provides teachers with essential information about students’ weaknesses, needs, obstacles, and deficits. Thus, teachers can implement the appropriate techniques and use the assessment results to amend their classroom instruction and enhance the learning abilities.

    •\tDiscourse – comprehension of orally presented stories of varying lexical-semantic and syntactic difficulty indexed by response accuracy to a set of 16 yes-no questions on explicit and implicit content of the stories. Each subtest was completed by at least 20 individuals with aphasia and 20 healthy age-matched controls. To maximize validity and reliability of the subtests, “poor” items were removed according to the following principles. First, items that were answered erroneously by two or more healthy participants were eliminated. Second, based on item difficulty and corrected-item-total correlation derived for the aphasia group, most sensitive and valid items were retained. Also, it was ensured that each influential psychometric property was represented in the refined set by a wide range of values. Thus, a final smaller set of items for each subtest was selected for further norming and standardization. We will discuss in detail the various conceptual and psychometric considerations that went into the design of the subtests and affected item selection.

    The Multi-Axial Gay Men's Inventory-Men's Short Version (MAGI-MSV) assesses internalized homophobia via 20 items and 3 dimensions. This study extended the psychometric examination of the MAGI-MSV. The instrument was administered to 228 ethnically diverse HIV-negative gay men seeking counseling in New York City (mean age = 35, age range = 16-70). Following principal axis factoring and parallel analyses, 4 factors emerged and 14 items were retained. The descriptive labels for factors included gay self-assurance and worth, public appearance of homosexuality, and impact of HIV/AIDS on homosexuality. The new, fourth factor was named maladaptive measures to eliminate homosexuality.

    Full Text Available Interest in self-esteem has been fuelled by the suggestion that level of self-esteem is associated with psychological well-being. In the present study, we translated the Rosenberg Self-Esteem Scale (RSES into the Dutch language and evaluated its psychometric properties in a sample of 442 adults. The results of both exploratory and confirmatory factor analyses confirmed that a single-factor solution provides the best fit. In addition, the Dutch RSES showed high internal consistency as well as high congruent validity. Overall, these findings support the usefulness of the Dutch RSES as a measure for global self-esteem.

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

    Institute of Scientific and Technical Information of China (English)

    1994-01-01

    In the ten years since the publication of Krashen’s theory on second language acquisition (SLA), the role of comprehensible input (CI) in the learning/acquiring of a language has received considerable attention (Krashen, 1982, 1985; Ellis, 1991, 1992; Long, 1983, 1985). As a result of these studies researchers now agree on the following points. Exposure to a language does not lead to acquisition; the personal accounts of so many language learners who have spent many years in a country or who have listened to endless hours of radio and television without being able to understand or speak the language attest to this fact.

  15. Modern psychometric approaches to analysis of scales for health-related quality of life

    DEFF Research Database (Denmark)

    Bjorner, Jakob Bue; Bech, Per

    2016-01-01

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

    Gregory, Virgil L

    2015-01-01

    The purpose of the author in this systematic psychometric review includes: providing social work researchers, educators, and administrators with a summary of descriptive psychometric information pertaining to scales which measure social workers' beliefs about research and social work practice, evaluating chronological changes in psychometric/statistical methodology, and summarizing the role current and future scale development efforts have in improving the use of evidence-based social work practice. Using predetermined inclusion and exclusion criteria, electronic databases and reference lists of included studies were reviewed and coded for methodological and psychometric properties. Seventeen studies satisfied inclusion and exclusion criteria. Eleven unique scales measuring social worker beliefs regarding research and social work practice were identified. The majority of scales and subscales had Cronbach's alphas that exceeded .70. Most of the scales had evidence of content, factorial, construct, and/or criterion validity. Strategies for improving psychometric research and implications for evidence-based social work practice are discussed.

  17. Psychometrics and its discontents: an historical perspective on the discourse of the measurement tradition.

    Science.gov (United States)

    Schoenherr, Jordan Richard; Hamstra, Stanley J

    2016-08-01

    Psychometrics has recently undergone extensive criticism within the medical education literature. The use of quantitative measurement using psychometric instruments such as response scales is thought to emphasize a narrow range of relevant learner skills and competencies. Recent reviews and commentaries suggest that a paradigm shift might be presently underway. We argue for caution, in that the psychometrics approach and the quantitative account of competencies that it reflects is based on a rich discussion regarding measurement and scaling that led to the establishment of this paradigm. Rather than reflecting a homogeneous discipline focused on core competencies devoid of consideration of context, the psychometric community has a history of discourse and debate within the field, with an acknowledgement that the techniques and instruments developed within psychometrics are heuristics that must be used pragmatically.

Panteleimon, Athens, GreeceBackground: No specific questionnaire has been developed to assess the health-related quality of life of thalassemia patients. Thus, the main objective of this study was to develop, according to psychometric standards, a self-administered Specific Thalassemia Quality of Life Instrument (STQOLI for adult patients.Methods: First, a qualitative phase was conducted to generate items and identify domains using the critical analysis incident technique and a literature review. A list of easily comprehensible, non-redundant items was defined using the Delphi technique and a pilot study on ten thalassemia patients. This phase involved both patients and experts. The second step was a quantitative validation phase comprising a study of 128 thalassemia patients in a single hospital. It was designed to select items, identify dimensions, and measure reliability and internal and concurrent validity. The psychometric and scaling properties of the proposed 41-item Specific Thalassemia Quality of Life Instrument were then assessed among patients recruited from the Thalassemia Unit at the General Hospital of Nikaia, Greece.Results: The final questionnaire had 41 items comprising four main domains and one global item about general health. The factorial structure was satisfactory (loading > 0.40 on each factor of the four domains for all items. Interscale correlations ranged from 0.06 to 0.78, Cronbach's α-coefficients were 0.78 for the psychosocial domain, 0.77 for the chelation domain, 0.72 for the transfusion domain, 0.81 for the disease and symptoms domain, and 0.840 for the total score of the questionnaire.Conclusion: The 41-item Specific Thalassemia Quality of Life Instrument seems to be a

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

    2015-01-01

    The aim was to test the construct validity of the Nurse Competence Scale. The Nurse Competence Scale has been used in hospital settings for various purposes in several countries. Despite this, confirmatory factor analyses are scarcely reported. The present study is based on re-analyses of data from 2007 (i.e. psychometric testing) and 593 newly graduated nurses working in various contexts were included. Confirmatory as well as exploratory factor analyses (Principal Component Analysis) were carried out. The original 7-factor model of the Nurse Competence Scale (73 items) was not confirmed. The exploratory factor analyses resulted in a Norwegian Nurse Competence Scale consisting of 46 items in the following competence categories: Planning and delivery of care, Teaching functions, Professional leadership, Research utilization and nursing values and Professional awareness. The results underline the needs for psychometric testing of an instrument after translation processes. The instrument is suitable for describing and comparing nurse competence for various reasons. It may also be helpful in creating competence development programs at an individual as well as at an organizational level. Further studies with a broader sample are recommended.

  1. Weight bias internalization scale: psychometric properties and population norms.

    Anja Hilbert

    Full Text Available OBJECTIVE: Internalizing the pervasive weight bias commonly directed towards individuals with overweight and obesity, co-occurs with increased psychopathology and impaired quality of life. This study sought to establish population norms and psychometric properties of the most widely used self-report questionnaire, the Weight Bias Internalization Scale (WBIS, in a representative community sample. DESIGN AND METHODS: In a survey of the German population, N = 1158 individuals with overweight and obesity were assessed with the WBIS and self-report measures for convergent validation. RESULTS: Item analysis revealed favorable item-total correlation of all but one WBIS item. With this item removed, item homogeneity and internal consistency were excellent. The one-factor structure of the WBIS was confirmed using confirmatory factor analysis. Convergent validity was shown through significant associations with measures of depressive and somatoform symptoms. The WBIS contributed to the explanation of variance in depressive and somatoform symptoms over and above body mass index. Higher WBIS scores were found in women than in men, in individuals with obesity than in individuals with overweight, and in those with lower education or income than those with higher education or income. Sex-specific norms were provided. CONCLUSIONS: The results showed good psychometric properties of the WBIS after removal of one item. Future research is warranted on further indicators of reliability and validity, for example, retest reliability, sensitivity to change, and prognostic validity.

    2017-01-01

    Recent research has suggested that metacognitions may play a role across the spectrum of addictive behaviours. The goal of our studies was to develop the first self-report scale of metacognitions about online gaming. We conducted two studies with samples of online gamers (n=225, n=348) to test the structure and psychometric properties of the Metacognitions about Online Gaming Scale and examined its capacity to predict weekly online gaming hours and Internet addiction. Exploratory and confirmatory factor analyses supported a three-factor solution: positive metacognitions about online gaming, negative metacognitions about the uncontrollability of online gaming, and negative metacognitions about the dangers of online gaming. Internal consistency, predictive and divergent validity were acceptable. All the factors of the Metacognitions about Online Gaming Scale correlated positively with weekly online gaming hours and Internet addiction. Regression analyses showed that negative metacognitions about the uncontrollability of online gaming and levels of Internet addiction were the only significant predictors of weekly online gaming hours, and that positive metacognitions about online gaming and negative metacognitions about the uncontrollability of online gaming were the only significant predictors of Internet addiction. The Metacognitions about Online Gaming Scale was shown to possess good psychometric properties, as well as predictive and divergent validity within the populations that were tested.

    2016-11-14

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

  4. Transfer Learning for Collaborative Filtering Using a Psychometrics Model

    2016-01-01

    Full Text Available In a real e-commerce website, usually only a small number of users will give ratings to the items they purchased, and this can lead to the very sparse user-item rating data. The data sparsity issue will greatly limit the recommendation performance of most recommendation algorithms. However, a user may register accounts in many e-commerce websites. If such users’ historical purchasing data on these websites can be integrated, the recommendation performance could be improved. But it is difficult to align the users and items between these websites, and thus how to effectively borrow the users’ rating data of one website (source domain to help improve the recommendation performance of another website (target domain is very challenging. To this end, this paper extended the traditional one-dimensional psychometrics model to multidimension. The extended model can effectively capture users’ multiple interests. Based on this multidimensional psychometrics model, we further propose a novel transfer learning algorithm. It can effectively transfer users’ rating preferences from the source domain to the target domain. Experimental results show that the proposed method can significantly improve the recommendation performance.

    2010-01-01

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

R., et al. (2007). Florida Obsessive-Compulsive Scale: development, reliability, and validity. Journal of Clinical Psychology, 63, 851-859]). Participants were 89 adults with OCD presenting for treatment at a specialty clinic. A trained clinician administered the Yale-Brown Obsessive Compulsive Scale and patients completed the FOCI, Obsessive-Compulsive Inventory-Revised, Beck Depression Inventory-Second Edition, and State Trait Anxiety Inventory at baseline and following 14 weekly or daily cognitive behavioral therapy sessions. The internal consistency of FOCI Symptom Checklist and Severity Scale were good, and the concurrent and divergent validity of the FOCI Symptom Checklist and Severity Scale was supported through its associations with clinician-rated OCD symptom severity, and self-reported OCD, depressive, and anxiety measures. In addition, sensitivity to cognitive-behavioral treatment effects was shown as the Severity Scale scores were significantly lower following treatment compared to baseline. These findings not only replicate Storch et al. [Storch, E. A., Stigge-Kaufman, D., Bagner, D., Merlo, L. J., Shapira, N. A., Geffken, G. R., et al. (2007). Florida Obsessive-Compulsive Scale: development, reliability, and validity.

    Full Text Available Abstract Background The NDI, COM and NPQ are evaluation instruments for disability due to NP. There was no Spanish version of NDI or COM for which psychometric characteristics were known. The objectives of this study were to translate and culturally adapt the Spanish version of the Neck Disability Index Questionnaire (NDI, and the Core Outcome Measure (COM, to validate its use in Spanish speaking patients with non-specific neck pain (NP, and to compare their psychometric characteristics with those of the Spanish version of the Northwick Pain Questionnaire (NPQ. Methods Translation/re-translation of the English versions of the NDI and the COM was done blindly and independently by a multidisciplinary team. The study was done in 9 primary care Centers and 12 specialty services from 9 regions in Spain, with 221 acute, subacute and chronic patients who visited their physician for NP: 54 in the pilot phase and 167 in the validation phase.

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

    OBJECTIVES: The costs of comprehensive cardiac rehabilitation are established and compared to the corresponding costs of usual care. The effect on health-related quality of life is analyzed. METHODS: An unprecedented and very detailed cost assessment was carried out, as no guidelines existed...... for the situation at hand. Due to challenging circumstances, the cost assessment turned out to be ex-post and top-down. RESULTS: Cost per treatment sequence is estimated to be approximately euro 976, whereas the incremental cost (compared with usual care) is approximately euro 682. The cost estimate is uncertain...... and may be as high as euro 1.877. CONCLUSIONS: Comprehensive cardiac rehabilitation is more costly than usual care, and the higher costs are not outweighed by a quality of life gain. Comprehensive cardiac rehabilitation is, therefore, not cost-effective....

    Context is very important factor that can't be ignored in speech communication. Context contributes much to understanding the meaning of words. The exact and thorough interpretation of words and utterance results from contexts. The relation is discussed between context and listening comprehension, and the functions of context are analyzed in listening. It is pointed out that the analysis of contextual clues is useful in understanding listening materials and also introduces some ways on contextual clues in listening so as to improve listening comprehension.

  12. Transport phenomena in strongly correlated Fermi liquids

    Comprehensive overview. Written by an expert of this topic. Provides the reader with current developments in the field. In conventional metals, various transport coefficients are scaled according to the quasiparticle relaxation time, {tau}, which implies that the relaxation time approximation (RTA) holds well. However, such a simple scaling does not hold in many strongly correlated electron systems, reflecting their unique electronic states. The most famous example would be cuprate high-Tc superconductors (HTSCs), where almost all the transport coefficients exhibit a significant deviation from the RTA results. To better understand the origin of this discrepancy, we develop a method for calculating various transport coefficients beyond the RTA by employing field theoretical techniques. Near the magnetic quantum critical point, the current vertex correction (CVC), which describes the electron-electron scattering beyond the relaxation time approximation, gives rise to various anomalous transport phenomena. We explain anomalous transport phenomena in cuprate HTSCs and other metals near their magnetic or orbital quantum critical point using a uniform approach. We also discuss spin related transport phenomena in strongly correlated systems. In many d- and f-electron systems, the spin current induced by the spin Hall effect is considerably greater because of the orbital degrees of freedom. This fact attracts much attention due to its potential application in spintronics. We discuss various novel charge, spin and heat transport phenomena in strongly correlated metals.

    Strongly irreducible submodules of modules are defined as follows: A submodule N of an R-module M is said to be strongly irreducible if for submodules L and K of M, the inclusion L ∩ K (∈) TV implies that either L (∈) N or K (∈) N. The relationship among the families of irreducible, strongly irreducible, prime and primary submodules of an .R-module M is considered, and a characterization of Noetherian modules which contain a non-prime strongly irreducible submodule is given.

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

    2012-01-01

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

  1. Assessing motivations for suicide attempts: development and psychometric properties of the inventory of motivations for suicide attempts.

    2013-10-01

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

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

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

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

    To report the development and psychometric evaluation of a scale to measure rural and remote (rural/remote) nurses' perceptions of the engagement of their workplaces in key dimensions of primary health care (PHC). Amidst ongoing PHC reforms, a comprehensive instrument is needed to evaluate the degree to which rural/remote health care settings are involved in the key dimensions that characterize PHC delivery, particularly from the perspective of professionals delivering care. This study followed a three-phase process of instrument development and psychometric evaluation. A literature review and expert consultation informed instrument development in the first phase, followed by an iterative process of content evaluation in the second phase. In the final phase, a pilot survey was undertaken and item discrimination analysis employed to evaluate the internal consistency reliability of each subscale in the preliminary 60-item Primary Health Care Engagement (PHCE) Scale. The 60-item scale was subsequently refined to a 40-item instrument. The pilot survey sample included 89 nurses in current practice who had experience in rural/remote practice settings. Participants completed either a web-based or paper survey from September to December, 2013. Following item discrimination analysis, the 60-item instrument was refined to a 40-item PHCE Scale consisting of 10 subscales, each including three to five items. Alpha estimates of the 10 refined subscales ranged from 0.61 to 0.83, with seven of the subscales demonstrating acceptable reliability (α ⩾ 0.70). The refined 40-item instrument exhibited good internal consistency reliability (α=0.91). The 40-item PHCE Scale may be considered for use in future studies regardless of locale, to measure the extent to which health care professionals perceive their workplaces to be engaged in key dimensions of PHC.

    There are presently no validated scales to adequately measure the stigma of suicide in the community. The Stigma of Suicide Scale (SOSS) is a new scale containing 58 descriptors of a "typical" person who completes suicide. To validate the SOSS as a tool for assessing stigma toward suicide, to examine the scale's factor structure, and to assess correlates of stigmatizing attitudes. In March 2010, 676 staff and students at the Australian National University completed the scale in an online survey. The construct validity of the SOSS was assessed by comparing its factors with factors extracted from the Suicide Opinion Questionnaire (SOQ). Three factors were identified: stigma, isolation/depression, and glorification/normalization. Each factor had high internal consistency and strong concurrent validity with the Suicide Opinion Questionnaire. More than 25% of respondents agreed that people who suicided were "weak," "reckless," or "selfish." Respondents who were female, who had a psychology degree, or who spoke only English at home were less stigmatizing. A 16-item version of the scale also demonstrated robust psychometric properties. The SOSS is the first attitudes scale designed to directly measure the stigma of suicide in the community. Results suggest that psychoeducation may successfully reduce stigma.

    This study examined the psychometric properties and criterion validity of a newly developed battery of executive function tasks for use in early childhood. The battery was included in the Family Life Project (FLP), a prospective longitudinal study of families who were over-sampled from low income and African American families at the birth of a new child (N = 1292). Ninety-nine percent (N = 1036) of children who participated in the age 5 home visit completed one or more (M = 5.8, Median = 6) of the six executive function tasks. Results indicated that tasks worked equally well for children residing in low and not low income homes, that task scores were most informative about the ability level of children in the low-average range, that performance on executive function tasks was best characterized by a single factor, and that individual differences on the EF battery were strongly related to a latent variable measuring overall academic achievement, as well as with individual standardized tests that measured phonological awareness, letter-word identification, and early math skills.

    Aims of this study were (a) to summarize the psychometric literature on the Mobility Inventory for Agoraphobia (MIA), (b) to examine the convergent and discriminant validity of the MIA's Avoidance Alone and Avoidance Accompanied rating scales relative to clinical severity ratings of anxiety disorders from the Anxiety Disorders Interview Schedule (ADIS), and (c) to establish a cutoff score indicative of interviewers' diagnosis of agoraphobia for the Avoidance Alone scale. A meta-analytic synthesis of 10 published studies yielded positive evidence for internal consistency and convergent and discriminant validity of the scales. Participants in the present study were 129 people with a diagnosis of panic disorder. Internal consistency was excellent for this sample, α=.95 for AAC and .96 for AAL. When the MIA scales were correlated with interviewer ratings, evidence for convergent and discriminant validity for AAL was strong (convergent r with agoraphobia severity ratings=.63 vs. discriminant rs of .10-.29 for other anxiety disorders) and more modest but still positive for AAC (.54 vs. .01-.37). Receiver operating curve analysis indicated that the optimal operating point for AAL as an indicator of ADIS agoraphobia diagnosis was 1.61, which yielded sensitivity of .87 and specificity of .73.

    Asperger's Syndrome (AS) is an autism spectrum disorder that is characterized by significant difficulties in social interaction and nonverbal communication, and restricted and repetitive patterns of behavior and interests. Difficulties with respect to pragmatic speech, reading emotional and social cues, differentiating between fact and fiction, and taking into account the influence of context on a statement are commonly described features. However, hitherto established questionnaires did not focus on these symptoms. In this study we present a short (11 questions) questionnaire which focuses on self-rated pragmatic speech abilities, the Freiburg Questionnaire of linguistic pragmatics (FQLP). Psychometric properties of the questionnaire were explored in a sample of 57 patients with Asperger's Syndrome, 66 patients with other psychiatric disorders, and a convenience sample of 56 people. Reliability analysis showed a high Cronbach's α. Strong correlations could be demonstrated for the FQLP with the Autism Quotient and the Empathy Quotient. Concerning divergent validity a moderate correlation was found between the FQLP and self-rated symptoms of personality disorders. No significant correlation was found between the FQLP and the vocabulary skills. The receiver operating characteristics curve showed an excellent diagnostic accuracy of the FQLP (.97). As the control group consisted of people without mental disorder and patients with different psychiatric disorders, the results indicate that the construct examined by the FQLP is quite specific to the peculiarities of AS. The FQLP is a reliable, brief and valid instrument. First results regarding sensitivity and specificity are highly promising.

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

    We examined the psychometric properties of the Dutch version of the Attitudes to Chocolate Questionnaire (ACQ), comparing the original three-factor model to a later-suggested two-factor model. We evaluated the construct validity of the ACQ by investigating the associations between the resulting factors and other eating-related questionnaires such as the Three Factor Eating Questionnaire and the Food Thought Suppression Inventory. Finally, we compared the scores on several scales regarding eating behavior between different groups (men versus women, dieters versus non-dieters and cravers versus non-cravers). A confirmatory factor analysis of the Dutch ACQ indicated the best global fit indices for the two-factor model, with the resulting factors being "Negative consequences and Guilt" and "Craving and emotional eating". Both factors were associated with other eating-related dimensions. However, craving seemed to be uniquely associated with the amount of chocolate consumed per week, whereas guilt correlated strongly with restraint. Finally, women scored higher on nearly all scales, but there was no significant gender difference with regard to chocolate consumption. Dieters reported more disinhibition, restraint, food-thought suppression and guilt, but they did not significantly differ from non-dieters with regards to their levels of craving, hunger nor consumption.

    Parental involvement in school-related tasks is associated with a number of positive outcomes across ethnic groups. However, a growing literature suggests that unique forms of involvement and barriers exist among linguistic minority Latino families. The Parental Schoolwork Support Measure-Youth (PSSM-Y) is introduced in this study along with the psychometric properties found with a sample of 133 Latino youth in Grades 5 through 7 from a public school in a low-income urban neighborhood. Exploratory factor analyses indicated the presence of three factors called direct support, language and support, and indirect support, which together accounted for 66.3% of the common variance in the 16-item version. Strong internal consistency and test-retest coefficients were found for the PSSM-Y in this sample. In addition, schoolwork support was correlated with youth depression, economic pressure, loneliness, and familism in the expected directions. The findings are discussed in terms of the potential utility of this measure for future school-based studies of Latino students and youth of immigrant backgrounds in the United States.

    The Rosenberg Self-Esteem (RSE) Scale is a commonly used measure of global self-esteem, an important element of mental health. The purpose of this cross sectional secondary analysis was to examine the psychometric properties of the scale in a sample of 98 African American single mothers. The RSE Scale showed adequate internal consistency with an alpha coefficient of .83. Two factors that accounted for a total of 54.7% of the variance were extracted. Self-esteem showed a strong negative relationship with both depressive symptoms and negative thinking. This study provides support for the internal consistency of the RSE Scale and partial support for its construct validity in this population. The RSE appears to represent a bidimensional construct of self-esteem for African American women, with the cultural influences of racial esteem and the rejection of negative stereotypes forming a separate and distinct aspect of this concept. The RSE Scale should be used and interpreted with caution in this population given these findings.

    Children may have a foundational role in efforts to raise community awareness about dementia. There is some qualitative work with children with a relative with dementia, but little work into the insights of children as general citizens without affected family. One issue is an absence of measurement tools; thus the study aimed to design and pilot a psychometrically sound self-report measure of dementia attitudes for children. Using a multi-staged scale development process, stakeholder and expert input informed a 52-item Kids Insight into Dementia Survey (KIDS). After a pretest of KIDS with 21 Australian schoolchildren aged 10-12 years, exploratory factor analysis and reliability and validity testing were run on a revised KIDS with data from 203 similar-aged schoolchildren. The KIDS was reduced from 52 to 14 items, and a three-factor solution identified: 'Personhood,' 'Stigma,' and 'Dementia Understanding.' A strong positive correlation with an adult measure of dementia attitudes (r = .76) and a moderate positive correlation with a child measure of attitudes towards older adults (r = .47) indicated good concurrent validity. Internal consistency of .83 indicated good reliability. Results support the use of KIDS as a tool to measure children's insight into dementia, and to evaluate dementia education initiatives targeting the youth.

    Full Text Available This study presents the psychometric properties of the Brazilian version of the five-item Mental Health Index (MHI-5. Participants were 524 subjects (69.8% women, aged from 18 to 88 years old (M = 38.3; SD = 13.26, from 17 Brazilian states. Exploratory and confirmatory factor analyses supported a single-factor solution. Reliability was assessed using alpha reliability, average variance extracted and composite reliability. Convergent validity was presented using the MHI-5, the Subjective Happiness Scale, the Satisfaction with Life Scale, and the General Health Questionnaire (GHQ-12. Discriminant validity, using the GHQ-12, showed that MHI-5 is a reliable measure to evaluate mental health. The scale presented strong evidence of validity and seems appropriate to evaluate mental health in the Brazilian population.

    The strong embedding conjecture states that any 2-connected graph has a strong embedding on some surface. It implies the circuit double cover conjecture: Any 2-connected graph has a circuit double cover.Conversely, it is not true. But for a 3-regular graph, the two conjectures are equivalent. In this paper, a characterization of graphs having a strong embedding with exactly 3 faces, which is the strong embedding of maximum genus, is given. In addition, some graphs with the property are provided. More generally, an upper bound of the maximum genus of strong embeddings of a graph is presented too. Lastly, it is shown that the interpolation theorem is true to planar Halin graph.

    The Evidence-Based Practice Attitude Scale (EBPAS) was developed in the United States to assess attitudes of mental health and welfare professionals toward evidence-based interventions. Although the EBPAS has been translated in different languages and is being used in several countries, all research on the psychometric properties of the EBPAS within youth care has been carried out in the United States. The purpose of this study was to investigate the psychometric properties of the Dutch version of the EBPAS. After translation into Dutch, the Dutch version of the EBPAS was examined in a diverse sample of 270 youth care professionals working in five institutions in the Netherlands. We examined the factor structure with both exploratory and confirmatory factor analyses and the internal consistency reliability. We also conducted multiple linear regression analyses to examine the association of EBPAS scores with professionals' characteristics. It was hypothesized that responses to the EBPAS items could be explained by one general factor plus four specific factors, good to excellent internal consistency reliability would be found, and EBPAS scores would vary by age, sex, and educational level. The exploratory factor analysis suggested a four-factor solution according to the hypothesized dimensions: Requirements, Appeal, Openness, and Divergence. Cronbach's alphas ranged from 0.67 to 0.89, and the overall scale alpha was 0.72. The confirmatory factor analyses confirmed the factor structure and suggested that the lower order EBPAS factors are indicators of a higher order construct. However, Divergence was not significantly correlated with any of the subscales or the total score. The confirmatory bifactor analysis endorsed that variance was explained both by a general attitude towards evidence-based interventions and by four specific factors. The regression analyses showed an association between EBPAS scores and youth care professionals' age, sex, and educational level. The

    Prenatal attachment (PA) is defined as the relationship that develops between a woman and her foetus. Three measurements exist for evaluating PA: the Maternal Foetal Attachment Scale (MFAS), the Maternal Antenatal Attachment Scale (MAAS) and the Prenatal Attachment Inventory (PAI). Of these three, only the PAI has been used in French. The overall objective of the current study was to evaluate the psychometric properties of this second measure of PA: the MAAS. This scale was developed in 1993 by Condon. The MAAS is a 19-item self-report questionnaire which allows for calculating a total attachment score and two subscale scores; one score estimating the quality of the affective attachment experience and the other that estimates the intensity of concern about the foetus. For each item, the future mother provided an appreciation on a 5-point Likert scale (1=absence of feelings for the foetus; 5=very strong feelings for the foetus). The sample was composed of 117 primiparous French females (27.5 ± 4.27 years) in the third trimester of pregnancy (32.84 ± 3.77 weeks of amenorrhea). The study was carried out over a period of 5 months (January-May 2012). Each woman was asked to provide demographic data, a French version of the MAAS, a validated French version of the PAI, and a scale evaluating depressive symptoms (Edinburgh PostNatal Depression Scale, EPDS). The MAAS demonstrated moderately good psychometric properties. Condon's two-factor structure of MAAS was not supported in our sample. Four factors were identified with exploratory factor analysis. Internal consistency was satisfactory for the global scale and for the factor 1 but not sufficiently adequate for the other factors. Concurrent validity was indicated by moderate correlations between the global MAAS scores with the total PAI score. A weak but significant inverse correlation was found between the MAAS and the EPDS suggesting good divergent validity. The authors suggest that additional research be conducted on

    Two main models are currently used to evaluate psychosocial factors at work: the Job Strain model developed by Karasek and the Effort-Reward Imbalance model. A French version of the first model has been validated for the dimensions of psychological demands and decision latitude. As regards the second one evaluating three dimensions (extrinsic effort, reward, and intrinsic effort), there are several versions in different languages, but until recently there was no validated French version. The objective of this study was to explore the psychometric properties of the French version of the Effort-Reward Imbalance model in terms of internal consistency, factorial validity, and discriminant validity. The present study was based on the GAZEL cohort and included the 10 174 subjects who were working at the French national electric and gas company (EDF-GDF) and answered the questionnaire in 1998. A French version of Effort-Reward Imbalance was included in this questionnaire. This version was obtained by a standard forward/backward translation procedure. Internal consistency was satisfactory for the three scales of extrinsic effort, reward, and intrinsic effort: Cronbach's Alpha coefficients higher than 0.7 were observed. A one-factor solution was retained for the factor analysis of the scale of extrinsic effort. A three-factor solution was retained for the factor analysis of reward, and these dimensions were interpreted as the factor analysis of intrinsic effort did not support the expected four-dimension structure. The analysis of discriminant validity displayed significant associations between measures of Effort-Reward Imbalance and the variables of sex, age, education level, and occupational grade. This study is the first one supporting satisfactory psychometric properties of the French version of the Effort-Reward Imbalance model. However, the factorial validity of intrinsic effort could be questioned. Furthermore, as most previous studies were based on male samples

    In this article, it is assumed that gender violence, or violence against women, has mainly a sociocultural basis. A scale (Adolescent Sexism Detection; ASD) to detect sexism in adolescents was developed and its psychometric properties were analysed. 245 adolescents between 14 and 17 years of age participated in the study. As a result of the factor analyses carried out, the hostile and benevolent dimensions of sexism were clearly differentiated. Convergent validity of the scale was confirmed by its high correlations with the Ambivalent Sexism Inventory (ASI). Participants scored higher in benevolent than in hostile sexism, an effect even stronger in female participants. These findings suggest that the ASD scale is a valid instrument to measure sexism among adolescents. The main findings of this study are compared to those obtained in other studies using the ASI. The potential of this scale to appropriately detect sexism among adolescents is discussed.

    This paper describes the development and psychometric properties of the Health and Functioning ICF-60 (HF-ICF-60) measure, based on the World Health Organization (WHO) 'International Classification of Functioning, Disability and Health: ICF' (2001). The aims of the present study were to test psychometric properties of the HF-ICF-60, developed as a measure that would be responsive to change in functioning through changes in health and nutritional status, as a prospective measure to monitor health and nutritional status of populations and to explore the relationship of the HF-ICF-60 with quality of life measures such as the World Health Organization WHOQOL-BREF quality of life assessment in relation to non-communicable diseases. The HF-ICF-60 measure consists of 60 items selected from the ICF by an expert panel, which included 18 items that cover Body Functions, 21 items that cover Activities and Participation, rated on five-point scales, and 21 items that cover Environmental Factors (seven items cover Individual Environmental Factors and 14 items cover Societal Environmental Factors), rated on nine-point scales. The HF-ICF-60 measure was administered to the Russian nationally representative sample within the Russian National Population Quality of Life, Health and Nutrition Survey, in 2004 (n = 9807) and 2005 (n = 9560), as part of the two waves of the Russian Longitudinal Monitoring Survey (RLMS). The statistical analyses were carried out with the use of both classical and modern psychometric methods, such as factor analysis, and based on Item Response Theory, respectively. The HF-ICF-60 questionnaire is a new measure derived directly from the ICF and covers the ICF components as follows: Body Functions, Activities and Participation, and Environmental Factors (Individual Environmental Factors and Societal Environmental Factors). The results from the factor analyses (both Exploratory Factor Analyses and Confirmatory Factor Analyses) show good support for the

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

    Full Text Available The understanding of user satisfaction and consumers of services is a necessity for those responsible for them. There’s a variety of instruments that assess the perceived quality but are criticized for several reasons: concepts, procedures, lack of specificity... EPOD is a scale with 29 items integrated in four dimensions, direct practical application which had been previously validated. However, nobody had checked the psychometric properties of the instrument. Therefore, the aim of this study is to determine them. The sample was 463 users of sports services who were given the instrument. The results show good internal and external validity, while it has a high reliability. Therefore, EPOD becomes a tool to assess the perceived quality of service provided by the sports organizations in a valid, reliable, simple and brief way, considering the different dimensions that make up the provision of sports services.

    Recent investigations emphasized the role of communication features on behavioral trust and reciprocity in economic decision making but no studies have been focused on the effect of communication on affective states in such a context. Thanks to advanced methods of computational psychometrics, in this study, affective states were deeply examined using simultaneous and synchronized recordings of gazes and psychophysiological signals in 28 female students during an investment game. Results showed that participants experienced different affective states according to the type of communication (personal versus impersonal). In particular, participants involved in personal communication felt more relaxed than participants involved in impersonal communication. Moreover, personal communication influenced reciprocity and participants' perceptions about trust and reciprocity. Findings were interpreted in the light of the Arousal/Valence Model and self-disclosure process. PMID:26339285

    More and more American older adults are relocating to retirement communities, and they experience challenges in adjusting to new surroundings that may increase their depression and mortality. An instrument not previously tested in the United States, the Index of Relocation Adjustment (IRA), may help in early identification of poor relocation adjustment. This study examined the psychometric properties of the IRA using secondary data from a convenience sample of 104 older adults who relocated to 6 retirement communities in Northeast Ohio. Cronbach's alpha was .86. The IRA was correlated with measures of positive cognitions (r = .48, p controllability (r = -.62, p IRA is potentially useful as a screening measure for early detection of poor adjustment among relocated older adults.

The scale was composed of 49 Likert scale items related to cognitive and metacognitive strategies. It was applied in a sample of 1,490 university students. The factor analysis revealed that 35 items had acceptable loadings and identified a three factor structure: Factor 1 - Cognitive and Metacognitive Self-regulation, Factor 2 - Internal Resource and Context regulation, and Factor 3 - Social regulation. Its internal consistency was assessed by Cronbach’s alpha and was .87 for the total scale, .86 for Factor 1, .71 for Factor 2 and .65 for Factor 3. The total variance explained was 26.6%. Further studies are suggested based on confirmatory factor analyses, so that the scale can be better utilized in psychoeducational evaluation.

    Full Text Available OBJECTIVES: The Nurses Work Functioning Questionnaire (NWFQ is a 50-item self-report questionnaire specifically developed for nurses and allied health professionals. Its seven subscales measure impairments in the work functioning due to common mental disorders. Aim of this study is to evaluate the psychometric properties of the NWFQ, by assessing reproducibility and construct validity. METHODS: The questionnaire was administered to 314 nurses and allied health professionals with a re-test in 112 subjects. Reproducibility was assessed by the intraclass correlations coefficients (ICC and the standard error of measurement (SEM. For construct validity, correlations were calculated with a general work functioning scale, the Endicott Work Productivity Scale (EWPS (convergent validity and with a physical functioning scale (divergent validity. For discriminative validity, a Mann Whitney U test was performed testing for significant differences between subjects with mental health complaints and without. RESULTS: All subscales showed good reliability (ICC: 0.72-0.86, except for one (ICC = 0.16. Convergent validity was good in six subscales, correlations ranged from 0.38-0.62. However, in one subscale the correlation with the EWPS was too low (0.22. Divergent validity was good in all subscales based on correlations ranged from (-0.06-(-0.23. Discriminative validity was good in all subscales, based on significant differences between subjects with and without mental health complaints (p<0.001-p = 0.003. CONCLUSION: The NWFQ demonstrates good psychometric properties, for six of the seven subscales. Subscale "impaired decision making" needs improvement before further use.

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

    This study evaluated the psychometric properties of the Adolescent Sleep Hygiene Scale (ASHS), a self-report measure assessing sleep practices theoretically important for optimal sleep. Data were collected on a community sample of 514 adolescents (16-19; 17.7 ± 0.4 years; 50% female) participating in the late adolescent examination of a longitudinal study on sleep and health. Sleep hygiene and daytime sleepiness were obtained from adolescent reports, behavior from caretaker reports, and sleep-wake estimation on weekdays from wrist actigraphy. Confirmatory factor analysis indicated the empirical and conceptually based factor structure were similar for six of the eight proposed sleep hygiene domains. Internal consistency of the revised scale (ASHSr) was α = 0.84; subscale alphas were: physiological: α = 0.60; behavioural arousal: α = 0.62; cognitive/emotional: α = 0.81; sleep environment: α = 0.61; sleep stability: α = 0.68; daytime sleep: α = 0.78. Sleep hygiene scores were associated positively with sleep duration (r = 0.16) and sleep efficiency (r = 0.12) and negatively with daytime sleepiness (r = -0.26). Results of extreme-groups analyses comparing ASHSr scores in the lowest and highest quintile provided further evidence for concurrent validity. Correlations between sleep hygiene scores and caretaker reports of school competence, internalizing and externalizing behaviours provided support for convergent validity. These findings indicate that the ASHSr has satisfactory psychometric properties for a research instrument and is a useful research tool for assessing sleep hygiene in adolescents. © 2013 European Sleep Research Society.

    To develop and psychometrically test the Jacelon Attributed Dignity Scale (JADS). The JADS was designed to measure self-perceived attributed dignity in community-dwelling older adults. Attributed dignity was conceived of as a state characteristic of the self. The JADS is a short, positively scored, norm-referenced, evaluation index designed to measure self-perceived attributed dignity during the last week. Instrument development and testing including psychometric properties, internal consistency, factor structure, temporal stability and construct validity. Using a quota sample, 289 older adults (65-99 years old) were recruited from senior centres in western New England to complete the JADS, demographic information, the Self-Esteem Scale and the Social Desirability Scale during 2010-2011. Descriptive statistics, exploratory factor analysis, construct validity and temporal stability were evaluated. The resulting positively scored 18-item scale has four factors with high internal consistency for each factor and the entire scale. Construct validity was established by examining correlations with instruments that measured self-esteem and social desirability. Attributed dignity is a unique concept that is stable over time. The JADS is an 18-item Likert-scaled instrument designed to measure attributed dignity. Attributed dignity is a concept with four factors and is defined as a cognitive component of the self-connoting self-value, perceived value from others, self in relation to others and behaving with respect. The importance of attributed dignity for older adults in relation to health, function, independence, quality of life and successful ageing can now be evaluated. © 2014 John Wiley & Sons Ltd.

    Evidence of psychometric support is needed for use of the Differentiation of Self Inventory with adolescents as a clinical assessment instrument to evaluate psychotherapeutic progress and outcomes, and for its use as a research instrument to evaluate the effectiveness of interventions on the basis of Bowen family systems theory. To examine the reliability and validity of the 46-item, self-report Differentiation of Self Inventory (DSI) for use with adolescents. An ex post facto research design was used to determine the psychometric properties of the DSI for adolescents, and to test theoretically grounded hypotheses drawn from Bowen theory that linked differentiation of self with chronic anxiety and symptom development. The DSI, the State-Trait Anxiety Inventory, and the Symptom Pattern Scale were administered to an ethnically diverse sample of 363 adolescents 14 to 19 years of age. The DSI full scale demonstrated good internal consistency reliability, with a Cronbach's alpha coefficient of.84. Factor analysis yielded a six-factor structure, representing the multidimensionality of the DSI items among adolescents. As hypothesized, differentiation of self mediated the relation between chronic anxiety and symptom development (p <.001), indicating that greater differentiation of self predicted fewer symptoms over and above chronic anxiety, and lending support to the construct validity of the DSI in adolescent populations. The results of this study support the use of the DSI with adolescents. Future longitudinal studies are needed for definitive causal conclusions regarding the role that differentiation of self plays as a mediator between the relation of chronic anxiety and symptom development.

    The purpose of this study is to assess the psychometric properties of a French version of the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), a self-report measure of posttraumatic stress disorder (PTSD) symptoms, and to further validate the existing English version of the measure. Undergraduate students (n = 838 English, n = 262 French) completed the PCL-5 as well as other self-report symptom measures of PTSD and depression online. Both the English and French versions PCL-5 total scores demonstrated excellent internal consistency (English: α = .95; French: α = .94), and strong convergent and divergent validity. Strong internal consistency was also observed for each of the four subscales for each version (α’s > .79). Test-retest reliability for the French version of the measure was also very good (r = .89). Confirmatory factor analysis indicated that the four-factor DSM-5 model was not a good fit of the data. The seven-factor hybrid model best fit the data in each sample, but was only marginally superior to the six-factor anhedonia model. The French version of the PCL-5 demonstrated the same psychometric qualities as both the English version of the same measure and previous versions of the PCL. Thus clinicians serving French-speaking clients now have access to this highly used screening instrument. With regards to the structural validity of the PCL-5 and of the new PTSD diagnostic structure of the DSM-5, additional research is warranted. Replication of our results in clinical samples is much needed. PMID:27723815

    We investigate the effect of strong disorder on a system with strong electronic repulsion. In the absence of disorder, the system has a d-wave superconducting ground state with strong non-BCS features due to its proximity to a Mott insulator. We find that while strong correlations make superconductivity in this system immune to weak disorder, superconductivity is destroyed efficiently when disorder strength is comparable to the effective bandwidth. The suppression of charge motion in regions of strong potential fluctuation leads to the formation of Mott insulating patches, which anchor a larger nonsuperconducting region around them. The system thus breaks into islands of Mott insulating and superconducting regions, with Anderson insulating regions occurring along the boundary of these regions. Thus, electronic correlation and disorder, when both are strong, aid each other in destroying superconductivity, in contrast to their competition at weak disorder. Our results shed light on why zinc impurities are efficient in destroying superconductivity in cuprates, even though it is robust to weaker impurities.

    We aimed to perform a comprehensive systematic review of the existing ataxia scales. We described the disorders for which the instruments have been validated and used, the time spent in its application, its validated psychometric properties, and their use in studies of natural history and clinical trials. A search from 1997 onwards was performed in the MEDLINE, LILACS, and Cochrane databases. The web sites ClinicalTrials.gov and Orpha.net were also used to identify the endpoints used in ongoing randomized clinical trials. We identified and described the semiquantitative ataxia scales (ICARS, SARA, MICARS, BARS); semiquantitative ataxia and non-ataxia scales (UMSARS, FARS, NESSCA); a semiquantitative non-ataxia scale (INAS); quantitative ataxia scales (CATSYS 2000, AFCS, CCFS and CCFSw, and SCAFI); and the self-performed ataxia scale (FAIS). SARA and ICARS were the best studied and validated so far, and their reliability sustain their use. Ataxia and non-ataxia scores will probably provide a better view of the overall disability in long-term trials and studies of natural history. Up to now, no clear advantage has been disclosed for any of them; however, we recommend the use of specific measurements of gait since gait ataxia is the first significant manifestation in the majority of ataxia disorders and comment on the best scales to be used in specific ataxia forms. Quantitative ataxia scales will be needed to speed up evidence from phase II clinical trials, from trials focused on the early phase of diseases, and for secondary endpoints in phase III trials. Finally, it is worth remembering that estimation of the actual minimal clinically relevant difference is still lacking; this, together with changes in quality of life, will probably be the main endpoints to measure in future therapeutic studies.

    While the most commonly employed burnout measure has been the Maslach Burnout Inventory (MBI), researchers have been troubled by some of the psychometric limitations of this instrument. The aim of this study was to analyze the psychometric properties of the "Spanish Burnout Inventory" (SBI). The psychometric properties were analysed with data from a sample of 277 Chilean professionals working to physical disabled people. The psychometric properties of the SBI were examined through the following analyses: confirmatory factor analysis, reliability Cronbach's alpha, and concurrent validity with the MBI. The hypothesized four factor model obtained an adequate data fit for the sample (chi2(164) = 285.32, p burnout in the Chilean cultural context.

  12. Measuring negative attitudes towards overweight and obesity in the German population - psychometric properties and reference values for the German short version of the Fat Phobia Scale (FPS.

    Directory of Open Access Journals (Sweden)

    Janine Stein

    Full Text Available Obesity is one of the leading public health problems worldwide. Obese individuals are often stigmatized and the psychosocial consequences of overweight and obesity are the subject of current research. To detect stigmatizing attitudes towards obese people, the Fat Phobia Scale (FPS was developed in the USA in the early nineties. In addition, the 14-item short form of the FPS was constructed. The FPS belongs to the most commonly used instruments for measuring negative attitudes towards obese people because of its good psychometric properties. For the recently developed German short form of the FPS, however, the comprehensive investigation of the psychometric properties and the determination of reference values are still pending. Thus, the main objectives of this study were the evaluation of the psychometric quality of the scale as well as the calculation of reference values.The study was based on a representative survey in the German general population. A sample of 1,657 subjects (18-94 years was assessed via structured telephone interviews including the 14-item German version of the FPS. Descriptive statistics and inference-statistical analyses were conducted. Reference values in terms of percentage ranks were calculated.Substantial evidence for the reliability and validity of the German short version of the FPS was found. This study, for the first time in Germany, provides age-specific reference values for the German short form of the FPS allowing the interpretation of individual test scores.Facing the far-reaching consequences of experienced stigmatization of obese individuals, these study results provide an important basis for further studies aiming at the investigation of negative attitudes towards overweight and obesity.

    Knowledge about predictors for reading comprehension in children with intellectual disabilities (ID) is still fragmented. This study compared reading comprehension, word decoding, listening comprehension, and reading related linguistic and cognitive precursor measures in children with mild ID and typically developing controls. Moreover, it was explored how the precursors related to reading achievement. Children with mild ID and typical controls were assessed on reading comprehension, decoding, language comprehension, and linguistic (early literacy skills, vocabulary, grammar) and cognitive (rapid naming, phonological short-term memory, working memory, temporal processing, nonverbal reasoning) precursor measures. It was tested to what extent variations in reading comprehension could be explained from word decoding, listening comprehension and precursor measures. The ID group scored significantly below typical controls on all measures. Word decoding was at or above first grade level in half the ID group. Reading comprehension in the ID group was related to word decoding, listening comprehension, early literacy skills, and temporal processing. The reading comprehension profile of children with mild ID strongly resembles typical early readers. The simple view of reading pertains to children with mild ID, with additional influence of early literacy skills and temporal processing. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Routine monitoring of cancer-related distress is recognized as essential to quality care and mandated by a major accrediting organization. However, to the authors' knowledge, few cancer-specific measures have been developed to date to assess the multiple cancer-related factors contributing to this distress. In the current study, the authors examined the psychometric properties of the Cancer and Treatment Distress (CTXD) measure over time in hematopoietic cell transplantation (HCT) recipients. As a secondary analysis of a multicenter randomized controlled clinical trial, adult patients undergoing autologous or allogeneic HCT completed patient-reported outcomes including the CTXD and the Medical Outcomes Study Short Form-36 (SF-36) before transplantation and 100 days and 180 days after HCT. Across 21 transplantation centers, a total of 701 patients consented, underwent transplantation, and were included in the current analyses, 645 of whom were alive at 100 days and 618 of whom were alive at 180 days. Internal consistency reliability was found to be strong for the overall CTXD at the 3 time points: Cronbach alphas (α) were .94, .95, and .95, respectively. Subscale reliability met hypothesized levels of an α>.70 across time, with the lowest reliability noted for the Identity subscale at 180 days (α = .77). Correlations with the SF-36 Mental Health subscale were higher than with the Physical Functioning subscale at each time point, thereby supporting convergent and discriminant validity. Strong correlations of the pretransplantation CTXD with the posttransplantation CTXD and SF-36 Mental Health subscale supported predictive validity. The CTXD is reliable and valid as a measure of cancer distress both before and after HCT. It may be a useful tool for measuring dimensions of distress and for defining those patients requiring treatment for distress during and after transplantation.

    Objective The majority of scales to measure family member distress in dementia are designed for community settings and do not capture the unique burdens of the nursing home (NH) environment. We report the psychometric properties of a new Family Distress in Advanced Dementia Scale for use in the NH setting. Design, Setting, Participants Cross-sectional questionnaire of 130 family member health care proxies of NH residents with advanced dementia in 31 Boston-area NHs. Methods Thirty-one initial items were evaluated, measuring the frequency over the past 3 months of sources of distress. Exploratory factor analysis identified domains of distress; Cronbach’s alpha was computed for each domain. Associations between the domains and other measures were evaluated using Pearson correlation coefficients, including measures of depression (PHQ-9), satisfaction with care (Satisfaction with Care at the End-of-Life in Dementia [SWC-EOLD]) and caregiver burden (Zarit Burden Interview short version). Results Factor analysis suggested three domains: Emotional Distress (9 items), Dementia Preparedness (5 items), and NH Relations (7 items). Cronbach’s alpha coefficients were 0.82, 0.75 and 0.83 respectively. The PHQ-9 correlated most strongly with the Emotional Distress factor (r = 0.34), the SWC-EOWD correlated most strongly with the NH Relations factor (r = 0.35), as did the Zarit Burden Scale (r = 0.50). Conculsions The Family Distress in Advanced Dementia Scale encompasses three domains of distress. This scale represents a much needed tool to assess distress among family members of NH residents with advanced dementia and provides a metric to evaluate interventions in the population.

  9. Strong interaction physics from hadronic atoms

    Batty, C. J.; Friedman, E.; Gal, A.

    1997-08-01

    Hadronic atoms provide a unique laboratory for studying strong interactions and nuclear medium effects at zero kinetic energy. Previous results from analyses of strong-interaction data consisting of level shifts, widths and yields in π-, K -, p¯ and ∑ - atoms are reviewed. Recent results from fits to comprehensive sets of data in terms of density-dependent optical potentials that respect the low-density limit, where the interaction tends to the free hadron nucleon value, are discussed. The importance of using realistic nuclear density distributions is highlighted. The introduction of density dependence in most cases significantly improves the fit to the data and leads to some novel results. For K - atoms, a substantial attraction of order 200 MeV in nuclear matter is suggested, with interesting repercussions for K¯ condensation and the evolution of strangeness in high-density stars. For p¯ atoms it is found that a reasonable p-wave strength can be accommodated in the fitted optical potential, in agreement with the energy dependence observed for some low-energy p¯N reactions. For ∑ - atoms, the fitted potential becomes repulsive inside the nucleus, implying that Σ hyperons generally do not bind in nuclei in agreement with recent measurements. This repulsion significantly affects calculated masses of neutron stars.

  10. ClassSTRONG: Classical simulations of Strong Field processes

    CERN Document Server

    Ciappina, M F; Lewenstein, M

    2013-01-01

    A set of Mathematica functions is presented to model classically two of the most important processes in strong field physics, namely high-order harmonic generation (HHG) and above-threshold ionization (ATI). Our approach is based on the numerical solution of the Newton-Lorentz equation of an electron moving on an electric field and takes advantage of the symbolic languages features and graphical power of Mathematica. Similarly as in the Strong Field Approximation (SFA), the effects of atomic potential on the motion of electron in the laser field are neglected. The SFA has proven to be an essential tool in strong field physics in the sense that it is able to predict with great precision the harmonic (in the HHG) and energy (in the ATI) limits. We have extended substantially the conventional classical simulations, where the electric field is only dependent on time, including spatial nonhomogeneous fields and spatial and temporal synthesized fields. Spatial nonhomogeneous fields appear when metal nanosystems int...

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

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

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

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

  17. The SNAP Strong Lens Survey

    2005-01-03

    Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical detection of strong lenses. Such a ''piggy-back'' survey might be expected even pessimistically to provide a catalogue of a few thousand new strong lenses, with the numbers dominated by systems of faint blue galaxies lensed by foreground ellipticals. After sketching out our strategy for detecting and measuring these galaxy lenses using the SNAP images, we discuss some of the scientific applications of such a large sample of gravitational lenses: in particular we comment on the partition of information between lens structure, the source population properties and cosmology. Understanding this partitioning is key to assessing strong lens cosmography's value as a cosmological probe.

    2016-01-01

    This paper reviews recent advances in the study of strongly interacting systems of dipolar molecules. Heteronuclear molecules feature large and tunable electric dipole moments, which give rise to long-range and anisotropic dipole-dipole interactions. Ultracold samples of dipolar molecules with long-range interactions offer a unique platform for quantum simulations and the study of correlated many-body physics. We provide an introduction to the physics of dipolar quantum gases, both electric and magnetic, and summarize the multipronged efforts to bring dipolar molecules into the quantum regime. We discuss in detail the recent experimental progress in realizing and studying strongly interacting systems of polar molecules trapped in optical lattices, with particular emphasis on the study of interacting spin systems and non-equilibrium quantum magnetism. Finally, we conclude with a brief discussion of the future prospects for studies of strongly interacting dipolar molecules.

    Full Text Available Abstract Background It would be useful to have psychometrically-sound measures of dental fear for Hispanics, who comprise the largest ethnic minority in the United States. We report on the psychometric properties of Spanish-language versions of two common adult measures of dental fear (Modified Dental Anxiety Scale, MDAS; Dental Fear Survey, DFS, as well as a measure of fear of dental injections (Needle Survey, NS. Methods Spanish versions of the measures were administered to 213 adults attending Hispanic cultural festivals, 31 students (who took the questionnaire twice, for test-retest reliability, and 100 patients at a dental clinic. We also administered the questionnaire to 136 English-speaking adults at the Hispanic festivals and 58 English-speaking students at the same college where we recruited the Spanish-speaking students, to compare the performance of the English and Spanish measures in the same populations. Results The internal reliabilities of the Spanish MDAS ranged from 0.80 to 0.85. Values for the DFS ranged from 0.92 to 0.96, and values for the NS ranged from 0.92 to 0.94. The test-retest reliabilities (intra-class correlations for the three measures were 0.69, 0.86, and 0.94 for the MDAS, DFS, and NS, respectively. The three measures showed moderate correlations with one another in all three samples, providing evidence for construct validity. Patients with higher scores on the measures were rated as being more anxious during dental procedures. Similar internal reliabilities and correlations were found in the English-version analyses. The test-retest values were also similar in the English students for the DFS and NS; however, the English test-retest value for the MDAS was better than that found in the Spanish students. Conclusion We found evidence for the internal reliability, construct validity, and criterion validity for the Spanish versions of the three measures, and evidence for the test-retest reliability of the Spanish

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

    Despite many studies there are still open questions about strong photoassociation in ultracold gases. Photoassociation occurs only at short range and thus can be used as a tool to probe and control the two-body correlation function in an interacting many-body system and to engineer Hamiltonians using dissipation. We propose the possibility to slow down decoherence by photoassociation through the quantum Zeno effect. This can realized by shining strong photoassociation light on the superposition of the lowest two hyperfine states of Lithium 6. NSF, ARO-MURI, Samsung, NSERC.

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

    The Quick-EBP-VIK is a new instrument for measuring nurses' value, implementation, and knowledge of EBP. Psychometric testing was conducted in two parts. Part 1 describes the tool development and validity testing which resulted in the development of a 25-item survey after receiving ≥0.80 Item-Level Content Validity Index for both clarity and relevance. Part 2 describes psychometric testing was necessary to assess additional types of validity and reliability. The purpose of this paper is to further describe the psychometric testing of the Quick-EBP-VIK survey instrument. This descriptive study was designed to assess test-retest reliability, internal consistency and construct validity via a web-based survey. The survey instrument was e-mailed to all nurses at the study hospital. Nurses who responded to the first survey (Wave 1) received another e-mail invitation to complete the survey instrument again (Wave 2) for the purpose of assessing the test-retest reliability of the instrument. A total of 1,177 deliverable e-mails were sent to all nursing staff at one free standing pediatric hospital with Magnet(®) designation in the northeast. A total of 382 nurses returned completed surveys, indicating a 32.5% response rate for Wave 1. A total of 131 nurses responded to Wave 2 indicating a response rate of 34.3%. The intraclass correlation coefficients for the items included in the final instrument ranged from 0.43 to 0.80 and were deemed sufficient. These represent a sufficient intraclass correlation coefficient. The Cronbach's Alpha values for each of the three domains are all higher than 0.7 indicating that the items of each of the measurement dimension are internally consistent. However, the composite reliability of the third domain was slightly lower than 0.7 when using Raykov's Rho. The Quick-EBP-VIK instrument has gone through rigorous comprehensive testing and has demonstrated good psychometric properties. © 2016 Sigma Theta Tau International.

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

    To explore the psychometric properties of 3 widely used measures of depression in a sample of individuals with traumatic brain injury (TBI) and major depressive disorder and refine them to maximize efficiency. Secondary analysis of data from a randomized controlled trial of cognitive-behavioral therapy for depression after TBI. Nationwide recruitment from community and clinical settings. One hundred adults within 10 years of complicated mild to severe TBI. Telephone and in-person cognitive-behavioral therapy. Patient Health Questionnaire-9 (PHQ-9), Symptom Checklist-20, and Hamilton Depression Rating Scale. We used Rasch rating scale analysis and multilevel modeling to investigate the 3 measures. Measurement properties of each of the depression measures were strong. We explored modifications to the rating scales to improve efficiency while retaining strong psychometric characteristics. Correlations among these revised measures were high. Treatment effects of each revised depression measure were compared using a multilevel model, and effect size estimates were comparable among the revised PHQ-9, Symptom Checklist-20, and Hamilton Depression Rating Scale. Although each of the 3 measures demonstrated adequate reliability, the efficiency of all 3 instruments was improved with rating scale analysis. The PHQ-9 required the fewest modifications and functions well as a measure of depression among those with TBI.

  6. Metacognition and Reading Comprehension

    2000-01-01

    @@ Introduction Reading is a mysterious process that has attracted attention from psychologists, reading researchers and educators alike for decades. Currently, reading is viewed as a meaningconstructing process where the reader interacts with the text by simultaneously using information from a variety of sources ranging from one's background knowledge of the content and about the world to the knowledge about the language in which the text is written (Mulling, 1994). Moreover, reading comprehension is achieved only after skillful orchestration of all the resources the reader possess when engaged in the act of reading. Among the various kinds of strategies a reader needs during the reading process are the monitoring strategies. In order to fully utilize the strategies, the reader needs to possess good metacognition. Metacognition refers to one's deliberate conscious control of one's cognition actions (Brown, 1980). Since it is crucial for success that we know what we know and what we don't know and, consequently what to do about what we know and don't know, it is not surprising to find the notion of metacognition being stressed in almost every situation of learning. Given the importance of metacognition in successful learning, the purpose of this paper is to explore the role metacognition plays in reading comprehension, and consequently, identify future research directions.

    This Comprehensive National Energy Strategy sets forth a set of five common sense goals for national energy policy: (1) improve the efficiency of the energy system, (2) ensure against energy disruptions, (3) promote energy production and use in ways that respect health and environmental values, (4) expand future energy choices, and (5) cooperate internationally on global issues. These goals are further elaborated by a series of objectives and strategies to illustrate how the goals will be achieved. Taken together, the goals, objectives, and strategies form a blueprint for the specific programs, projects, initiatives, investments, and other actions that will be developed and undertaken by the Federal Government, with significant emphasis on the importance of the scientific and technological advancements that will allow implementation of this Comprehensive National Energy Strategy. Moreover, the statutory requirement of regular submissions of national energy policy plans ensures that this framework can be modified to reflect evolving conditions, such as better knowledge of our surroundings, changes in energy markets, and advances in technology. This Strategy, then, should be thought of as a living document. Finally, this plan benefited from the comments and suggestions of numerous individuals and organizations, both inside and outside of government.

    This special issue contains papers presented at the International Conference on Strongly Coupled Coulomb Systems (SCCS), held from 29 July-2 August 2008 at the University of Camerino. Camerino is an ancient hill-top town located in the Apennine mountains of Italy, 200 kilometres northeast of Rome, with a university dating back to 1336. The Camerino conference was the 11th in a series which started in 1977: 1977: Orleans-la-Source, France, as a NATO Advanced Study Institute on Strongly Coupled Plasmas (hosted by Marc Feix and Gabor J Kalman) 1982: Les Houches, France (hosted by Marc Baus and Jean-Pierre Hansen) 1986: Santa Cruz, California, USA (hosted by Forrest J Rogers and Hugh E DeWitt) 1989: Tokyo, Japan (hosted by Setsuo Ichimaru) 1992: Rochester, New York, USA (hosted by Hugh M Van Horn and Setsuo Ichimaru) 1995: Binz, Germany (hosted by Wolf Dietrich Kraeft and Manfred Schlanges) 1997: Boston, Massachusetts, USA (hosted by Gabor J Kalman) 1999: St Malo, France (hosted by Claude Deutsch and Bernard Jancovici) 2002: Santa Fe, New Mexico, USA (hosted by John F Benage and Michael S Murillo) 2005: Moscow, Russia (hosted by Vladimir E Fortov and Vladimir Vorob'ev). The name of the series was changed in 1996 from Strongly Coupled Plasmas to Strongly Coupled Coulomb Systems to reflect a wider range of topics. 'Strongly Coupled Coulomb Systems' encompasses diverse many-body systems and physical conditions. The purpose of the conferences is to provide a regular international forum for the presentation and discussion of research achievements and ideas relating to a variety of plasma, liquid and condensed matter systems that are dominated by strong Coulomb interactions between their constituents. Each meeting has seen an evolution of topics and emphases that have followed new discoveries and new techniques. The field has continued to see new experimental tools and access to new strongly coupled conditions, most recently in the areas of warm matter, dusty plasmas

    The aim of the present study was to evaluate the psychometric properties of the Competence and Adherence Scale for Cognitive Behavioral Therapy (CAS-CBT). The CAS-CBT is an 11-item scale developed to measure adherence and competence in cognitive-behavioral therapy (CBT) for anxiety disorders in youth. A total of 181 videotapes from the treatment sessions in a randomized controlled effectiveness trial (Wergeland et al., 2014) comprising youth (N = 182, M age = 11.5 years, SD = 2.1, range 8-15 years, 53% girls, 90.7% Caucasian) with mixed anxiety disorders were assessed with the CAS-CBT to investigate interitem correlations, internal consistency, and factor structure. Internal consistency was good (Cronbach's alpha = .87). Factor analysis suggested a 2-factor solution with Factor 1 representing CBT structure and session goals (explaining 46.9% of the variance) and Factor 2 representing process and relational skills (explaining 19.7% of the variance). The sum-score for adherence and competence was strongly intercorrelated, r = .79, p .40, n = 10 videotapes) and also good to excellent interrater reliability when compared to expert raters (ICC = .83 for adherence and .64 for competence, n = 26 videotapes). High rater stability was also found (n = 15 videotapes). The findings suggest that the CAS-CBT is a reliable measure of adherence and competence in manualized CBT for anxiety disorders in youth. Further research is needed to investigate the validity of the scale and psychometric properties when used with other treatment programs, disorders and treatment formats. (PsycINFO Database Record

    2010-01-01

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

    Full Text Available Purpose: This research focuses on the construction and validation of a scale designed to assess the quality of the supervised classes: Interaction on Supervised Classes Scale (ISCS. Design/methodology/approach: This is a descriptive correlational study. For the construction of the scale three phases were performed in which different experts assessed the adequacy of the items. Finally, the psychometric properties of the final version were studied in a sample of 314 consumers (69.1% women aged between 18 and 77 with an average of 39.33 years (SD=12.25. Findings: The scale presents adequate validity and reliability, being a useful tool for measuring the interaction in Supervised Classes. Research limitations/implications: The sampling, non-probabilistic or convenience, have taken the sample of a unique sports facility and the small sample size. Practical implications: The ISCS allows managers to receive better feedback, allowing them to obtain deeper insight into the quality and satisfaction of the service. According to its results, the managers may implement different strategies to improve quality in a key service within sports centers. Originality/value: For the first time the interaction between customers and between customers and employees is evaluated both inside and outside the center, a topic that had not yet been studied in the scientific literature. The scale can be applied to any type of directed activity, and will allow a greater understanding of the quality of service.

    Workplace dietary intervention studies in low- and middle-income countries using psychometrically sound measures are scarce. This study aimed to validate a nutrition knowledge questionnaire (NQ) and its utility in evaluating the changes in knowledge among participants of a Nutrition Education Program (NEP) conducted at the workplace. A NQ was tested for construct validity, internal consistency and discriminant validity. It was applied in a NEP conducted at six workplaces, in order to evaluate the effect of an interactive or a lecture-based education programme on nutrition knowledge. Four knowledge domains comprising twenty-three items were extracted in the final version of the NQ. Internal consistency of each domain was significant, with Kuder-Richardson formula values>0·60. These four domains presented a good fit in the confirmatory factor analysis. In the discriminant validity test, both the Expert and Lay groups scored>0·52, but the Expert group scores were significantly higher than those of the Lay group in all domains. When the NQ was applied in the NEP, the overall questionnaire scores increased significantly because of the NEP intervention, in both groups (Pnutrition knowledge among participants of NEP at the workplace. According to the NQ, an interactive nutrition education had a higher impact on nutrition knowledge than a lecture programme.

    Full Text Available Objective: This study aimed to examin the psychometric characteristics of the Persian version of Reproductive Health Assessment Questionnaire for Women of Reproductive Age (RHAQWRA.Materials and methods: This study was a cross sectional study. We selected 150 women aged 18- 45 years based on convenience sampling method who lived in the Quake-hit areas  in eastern part of Iran in 2013. Some previously recognized and established instructions were undertaken in translating and adapting the RHAQWRA questionnaire culturally. We sought help and feedback from teenagers and experts in the fields of midwifery, sociology, and epidemiology to establish the face and content validity of the questionnaire. To examine the test-retest reliability indices of all the items, we used Kappa and McNemar tests.Results: The Content Validity Index (CVI and Content Validity Ratio (CVR scores for RHAQWRA were above 0.70. Results from Kappa and McNemar tests indicated a high degree of test-retest reliability. In order to evaluate the construct validity, known- group comparison (women with and without unwanted pregnancy was used. The internal consistency reliability indexes for the subscales obtained through Cronbach’s alpha were between 0.68 and 0.87.Conclusion: The findings suggest that the Iranian version of RHAQWRA is a valid and reliable questionnaire which can be used for measuring reproductive health needs during disasters.

    To test the psychometric properties of a boundary spanning measure by nurse managers. The health-care environment requires hospital units to coordinate efforts autonomously across their boundaries and to manage relationships with other professionals, units and departments. Boundary spanning has become increasingly important for first-line nurse managers as unit gatekeepers; however, the available measures are limited. The 30-item instrument was developed from a literature review. Survey participants were 4918 nurses at 231 hospital units. Statistical analyses of construct validity and internal consistency were performed. Furthermore, the correlation between nurses' scores on the Nurse Managers Boundary Spanning Scale and nurses' evaluations of their managers were examined. Three factors and 26 items were derived from factor analyses: connecting and mediating, informing and feedback utilisation, and resource acquisition. Cronbach's subscales' alpha coefficients were above 0.9. Correlation analysis indicated that the Nurse Managers Boundary Spanning Scale score correlated with nurses' positive perceptions of their managers. This study demonstrates tentative support for the validity and reliability of the Nurse Managers Boundary Spanning Scale. Although further study is needed, the Nurse Managers Boundary Spanning Scale shows possibilities as a new measurement of nursing leadership. This study underscores measures to build on nurse managers' roles by building on the limited research available. © 2016 John Wiley & Sons Ltd.

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

    To translate and culturally adapt the Mayo Elbow Performance Score (MEPS), a widely used instrument for evaluating disability associated with elbow injuries, into Turkish (MEPS-T) and to determine psychometric properties of the translated version. The MEPS was translated into Turkish using published methodological guidelines. The measurement properties of the MEPS-T (construct validity and floor and ceiling effects) were tested in 91 patients with elbow pathology. The reproducibility of the MEPS-T was tested in 59 patients over 7-14 days. The responsiveness of the MEPS-T was tested in a subgroup of 46 patients diagnosed with lateral epicondylitis and who received conservative treatment for 6 weeks. The interclass correlation coefficient (ICC) was used to estimate the test-retest reliability. The construct validity was analyzed with the disabilities of the arm, shoulder and hand (DASH), Visual Analog Scale (VAS) and the Short Form 36 (SF-36). Effect size (ES) was used to assess the responsiveness. The distribution of floor and ceiling effects was determined. The MEPS-T showed very good test-retest reliability (ICC 0.89). The correlation coefficients between the MEPS-T and DASH and VAS were -0.61 and -0.53, respectively (p elbow disease.

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

    Full Text Available The purpose of this study was to assess the psychometric properties of the Burnout Inventory for Referees (BIR in Portuguese in a sample of professional soccer referees and to explore the nomological validity of the inventory through concurrent validation. The analysis showed a factorial structure of burnout for the referees with one second order factor and three first order factors; physical and emotional exhaustion, reduced sense of accomplishment and sport devaluation. A cross-validation procedure showed that the factor structure was replicable, and the inventory demonstrated internal reliability as well as convergent and discriminant validity. In addition, the study assessed the concurrent validity of the inventory by examining the correlation between the scores of the Burnout Inventory for Referees and the scores of the Profile of Mood States (POMS. The subscales of burnout and total burnout were positively correlated with tension, depression, anger, fatigue and confusion and negatively with vigor, as expected. In conclusion, the Portuguese version of BIR presents good evidence of validity and reliability in the assessment of referees who may be at risk of suffering from burnout.

    Full Text Available The Tonic Immobility Scale has been only studied in abuse and/or sexual assault survivors, but tonic immobility (TI also occurs after other types of traumatic events. Consequently, we modified the scale for this purpose and studied its factor structure, internal consistency, and convergent, divergent and discriminant validity in 392 university students, most of whom had suffered one or more traumatic events of various kinds. The Fear subscale of the Modified Tonic Immobility Scale (MTIS showed very low internal consistency, and must be eliminated or reformulated. Discrimination indices of items 5 and 8 were very low, and tríese items must be reformulated or removed. After removing the five previous items, the shortened version of the MTIS had a one-factor structure, although model fit was not completely satisfactory. This scale showed acceptable levels of reliability, convergent validity with post-traumatic symptomatology, divergent validity with measures of depression and anxiety, and discriminant validity differentiating between groups that had and had not experienced traumatic events. The psychometric properties of the shortened version of the MTIS should be studied further. It may also be advisable to add new items of TI in order to establish whether this is a construct with more than one dimension.

    Full Text Available Nowadays, teaching statistics is almost undisputedly always done using some sort of software for carrying out the computations. Indeed, the range of choices available for that purpose is wide and with a lot of variety. The present work describes the capabilities of one of the systems currently available for teaching of statistics: ViSta, the Visual Statistics System. As ViSta’s developers, we wish to point out the following features as specially appealing for using it at the classroom: a price and availability, it is free and can be downloaded on-line; b flexibility, it is an open system, extensible and adaptable for different users and needs; c simplicity, it has a simple and intuitive user interface that facilitates the management, transformation and data analysis; and d its graphical power, as it implements visualization methods that allow carrying out demonstrations of concepts and data analysis techniques. These capabilities are illustrated using a specific application to the teaching of psychometrics. The limitations and perspectives of development of the system are finally discussed.

    2011-11-01

    Desire thinking is a voluntary cognitive process involving verbal and imaginal elaboration of a desired target. Recent research has highlighted the role of desire thinking in the maintenance of addictive, eating and impulse control disorders. The goal of this research project was to develop the first self-report measure of desire thinking. In Study 1 we constructed the Desire Thinking Questionnaire (DTQ) and conducted a preliminary factor analysis which identified two factors. The first factor concerned the perseveration of verbal thoughts about desire-related content and experience and was named 'Verbal Perseveration'. The second factor concerned the tendency to prefigure images about desire-related content and experience and was named 'Imaginal Prefiguration'. In Study 2 we performed a confirmatory factor analysis which provided support for this two factor solution, with both factors achieving adequate internal consistency. Divergent validity was also established through correlation analyses. In Study 3 the temporal stability of the DTQ was examined and confirmed. Finally, in Study 4, the predictive validity of the DTQ in a sample of alcohol abusers was investigated. The DTQ was shown to possess good psychometric properties, as well as divergent and predictive validity. This self-report measure may aid future research into desire thinking and craving, as well as facilitate assessment and case formulation within the context of addictive, eating and impulse control disorders.

    Background and aims The past decade has seen an increased interest in understanding hypersexual behavior and its associated features. Beyond the obvious risks for sexually transmitted infections, there is a paucity of literature examining specific challenges encountered by hypersexual individuals. This study investigated and developed a new scale, the Hypersexual Behavior Consequences Scale (HBCS), to assess the various consequences reported among hypersexual patients. Methods Participants were drawn from a sample of patients recruited in a DSM-5 Field Trial for Hypersexual Disorder (HD). Participants completed the Hypersexual Behavior Inventory, a structured diagnostic interview to assess for psychopathology and HD, and self-report measures of personality, life satisfaction, and the initial item pool for the HBCS. Results Factor analysis reduced the HBCS items to a single factor solution which showed high internal consistency and stability over time. Higher HBCS scores were positively correlated with higher levels of emotional dysregulation, impulsivity, and stress proneness and lower levels of satisfaction with life and happiness. HBCS scores among the hypersexual patients were significantly higher than non-hypersexual patients. Conclusions The HBCS possesses good psychometric properties and appears to capture various consequences associated with the DSM-5 proposed criteria for HD. The HBCS can be used to aid clinicians and researchers in identifying consequences associated with hypersexual behavior. The HBCS may also prove a useful tool to guide treatment interventions aimed at reducing the negative impact of hypersexuality in patient populations.

    To revise conversion disorder scale and to establish the psychometric properties of the revised scale. This case-control study was conducted from February to June, 2014, at the Government College University, Lahore, Pakistan, and comprised schoolchildren and children with conversion disorder. In order to generate items for revised version of conversion disorder scale, seven practising mental health professionals were consulted. A list of 42 items was finalised for expert ratings. After empirical validation, a scale of 40 items was administered on the participants and factor analysis was conducted. Of the240 participants, 120(50%) were schoolchildren (controls group) and 120(50%)were children with conversion disorder (clinical group).The results of factor analysis revealed five factors (swallowing and speech symptoms, motor symptoms, sensory symptoms, weakness and fatigue, and mixed symptoms) and retention of all 40 items of revised version of conversion disorder scale. Concurrent validity of the revised scale was found to be 0.81 which was significantly high. Similarly, discriminant validity of the scale was also high as both clinical and control groups had significant difference (pconversion disorder scale was 76% sensitive to predicting conversion disorder while specificity showed that the scale was 73% accurate in specifying participants of the control group. The revised version of conversion disorder scale was a reliable and valid tool to be used for screening of children with conversion disorder.

    Full Text Available This study presents the psychometric properties of the Brazilian version of the Positivity Scale (P-Scale. Participants were 730 subjects (65% women, aged from 17 to 70 years old (M = 31.0 years; SD = 11.43, from 21 Brazilian states. The sample was randomly split in two halves to cross-validate the results. With the first half of the sample (n1 = 365, an exploratory factor analysis (EFA was conducted. With the second half of the sample (n2 = 365, a confirmatory factor analysis (CFA assessed the fit of the exploratory model. Convergent validity and group differences were also evaluated. The EFA and CFA presented a one-dimensional structure for the P-Scale. Moderate correlations were found between the P-Scale and mental-health, subjective happiness and life-satisfaction. The levels of positivity presented a low positive correlation with age, educational level and financial income. Slightly significant effects were found for occupational status and marital status. Positivity appears to be more closely related to personal dispositions than to sociodemographic aspects. Our results suggest that the P-Scale is a reliable measure with which to evaluate the levels of positivity in Brazil.

    For the first time in history, it is possible to study human behavior on great scale and in fine detail simultaneously. Online services and ubiquitous computational devices, such as smartphones and modern cars, record our everyday activity. The resulting Big Data offers unprecedented opportunities for tracking and analyzing behavior. This paper hypothesizes the applicability and impact of Big Data technologies in the context of psychometrics both for research and clinical applications. It first outlines the state of the art, including the severe shortcomings with respect to quality and quantity of the resulting data. It then presents a technological vision, comprised of (i) numerous data sources such as mobile devices and sensors, (ii) a central data store, and (iii) an analytical platform, employing techniques from data mining and machine learning. To further illustrate the dramatic benefits of the proposed methodologies, the paper then outlines two current projects, logging and analyzing smartphone usage. One such study attempts to thereby quantify severity of major depression dynamically; the other investigates (mobile) Internet Addiction. Finally, the paper addresses some of the ethical issues inherent to Big Data technologies. In summary, the proposed approach is about to induce the single biggest methodological shift since the beginning of psychology or psychiatry. The resulting range of applications will dramatically shape the daily routines of researches and medical practitioners alike. Indeed, transferring techniques from computer science to psychiatry and psychology is about to establish Psycho-Informatics, an entire research direction of its own.

    2015-01-01

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

    The authors review research on children's reading motivation and its relation to their reading comprehension. They begin by discussing work on the development of school motivation in general and reading motivation in particular, reviewing work showing that many children's reading motivation declines over the school years. Girls tend to have more positive motivation for reading than do boys, and there are ethnic differences in children's reading motivation. Over the last 15 years researchers have identified in both laboratory and classroom-based research instructional practices that positively impact students' reading motivation and ultimately their reading comprehension. There is a strong need for researchers to build on this work and develop and study in different age groups of children effective classroom-based reading motivation instructional programs for a variety of narrative and informational materials.

    Travel, especially if it is international, often means major changes for the family. Family physicians should assess the epidemiologic risk and psychosocial significance of travel or relocation in light of the family's life-cycle stage and antecedent health. Using core references, which are kept current in partnership with public health agencies, family physicians are able to provide comprehensive immunization, medications, and patient education for all travel risks. Families are given medical record summaries and recommended sources of care at their destination. Eight weeks after their return patients are reassessed for newly acquired illness and helped to integrate the perspectives gained during the travel into the family's future dynamics. Taking advantage of growing travel medicine opportunities, family medicine educators should base the care of travelers and teaching of residents on defined competence priorities. Travelers' health provides a mutually rewarding model of shared care with public health consultants in the community medicine curriculum.

    Perceived control is a construct with important theoretical and clinical implications for healthcare providers, yet practical application of the construct in research and clinical practice awaits development of an easily administered instrument to measure perceived control with evidence of reliability and validity. To test the psychometric properties of the Control Attitudes Scale-Revised (CAS-R) using a sample of 3,396 individuals with coronary heart disease, 513 patients with acute myocardial infarction, and 146 patients with heart failure. Analyses were done separately in each patient group. Reliability was assessed using Cronbach's alpha to determine internal consistency, and item homogeneity was assessed using item-total and interitem correlations. Validity was examined using principal component analysis and testing hypotheses about known associations. Cronbach's alpha values for the CAS-R in patients with coronary heart disease, acute myocardial infarction, and heart failure were all greater than .70. Item-total and interitem correlation coefficients for all items were acceptable in the groups. In factor analyses, the same single factor was extracted in all groups, and all items were loaded moderately or strongly to the factor in each group. As hypothesized in the final construct validity test, in all groups, patients with higher levels of perceived control had less depression and less anxiety compared with those of patients who had lower levels of perceived control. This study provides evidence of the reliability and validity of the 8-item CAS-R as a measure of perceived control in patients with cardiac illness and provides important insight into a key patient construct.

    Policy makers and healthcare organizations are calling for expansion of the nurse practitioner (NP) workforce in primary care settings to assure timely access and high-quality care for the American public. However, many barriers, including those at the organizational level, exist that may undermine NP workforce expansion and their optimal utilization in primary care. This study developed a new NP-specific survey instrument, Nurse Practitioner Primary Care Organizational Climate Questionnaire (NP-PCOCQ), to measure organizational climate in primary care settings and conducted its psychometric testing. Using instrument development design, the organizational climate domain pertinent for primary care NPs was identified. Items were generated from the evidence and qualitative data. Face and content validity were established through two expert meetings. Content validity index was computed. The 86-item pool was reduced to 55 items, which was pilot tested with 81 NPs using mailed surveys and then field-tested with 278 NPs in New York State. SPSS 18 and Mplus software were used for item analysis, reliability testing, and maximum likelihood exploratory factor analysis. Nurse Practitioner Primary Care Organizational Climate Questionnaire had face and content validity. The content validity index was .90. Twenty-nine items loaded on four subscale factors: professional visibility, NP-administration relations, NP-physician relations, and independent practice and support. The subscales had high internal consistency reliability. Cronbach's alphas ranged from.87 to .95. Having a strong instrument is important to promote future research. Also, administrators can use it to assess organizational climate in their clinics and propose interventions to improve it, thus promoting NP practice and the expansion of NP workforce.

    Full Text Available This study aimed to validate a Chinese's adaption of the Cognitive Emotion Regulation Questionnaire for children (CERQ-Ck. This self-report instrument evaluates nine cognitive emotion regulation strategies that can be used by children after experiencing a negative life event. The CERQ-Ck was evaluated in a sample of 1403 elementary students between the ages of 9 and 11 by using cluster sampling. All the item-correlation coefficients for CERQ-Ck were above 0.30. The internal consistencies of the nine factors suggested moderate reliability (0.66 to 0.73. Confirmatory factor analysis (CFA indicated that the current version had the same structure as the original instrument (Tucker-Lewis index = 0.912, comparative fit index = 0.922, root mean square error of approximation = 0.032, standardized root mean square residual = 0.044. A second-order factor and a third-order factor structure were also found. Test-retest correlations (0.53 to 0.70, ps < 0.01 over a period of 1 month, which ranged from acceptable to moderately strong were obtained from a random and stratified subsample of elementary students (N = 76. In addition, we analyzed convergent validity in relation to CERQ-Ck and the Chinese version of the Children's Depression Inventory model dimensions with a subsample of 1083 elementary students. Multiple-group CFA confirmed the measurement invariance for both the male and female groups (ΔCFI < 0.01, ΔRMSEA < 0.015. Overall, results indicate that CERQ-Ck has similar psychometric properties to the original instrument as well as with adequate reliability and validity to investigate the nine cognitive emotion regulation strategies during late childhood developmental periods.

    Full Text Available Pfeffer’s Functional Activities Questionnaire (FAQ is one of the most commonly employed tools in studies on pathological cognitive ageing. Despite the different versions of the questionnaire translated for use in clinical practice, few studies have analyzed the psychometric properties of the Brazilian version of the FAQ (P-FAQ. Thus, the aim of the present study was to analyze the P-FAQ with regard to internal consistency, factorial structure and associations with demographic factors (age, sex and schooling, depressive symptoms, cognitive measures and other measures of functionality. One hundred sixty-one older adults were divided into four groups (91 with dementia, 46 with mild cognitive impairment, 11 with psychiatric disorders and 13 healthy controls. All participants were evaluated by cognitive, behavioral and functional tests and scales. Their caregivers answered the P-FAQ. The questionnaire showed high internal consistency (α = 0.91. Factor analysis revealed a two-factor structure, which, accounted for 66% of the total variance. The P-FAQ was not correlated with demographic factors, was weakly correlated with depressive symptoms (ϱ = 0.271, p < 0.01, R² = 7% and strongly correlated with cognitive measures (Matttis Dementia Rating Scale total score: ϱ = -0.574, p < 0.01, R² = 33% as well as complex instrumental activities of daily living (ϱ = -0.845, p < 0.01, R² = 71%. Cognitive performance and depression status were independent predictors of P-FAQ scores in regression models. The present findings indicate that the P-FAQ has satisfactory reliability, internal consistency, construct validity and ecological validity. Therefore, this questionnaire can be used in clinical practice and research involving the Brazilian population of older adults.

    Happiness is an important indicator of mental and physical health. It has been emphasized as one kind of well-being, and its definition varies from culture to culture. The main objective of the present study was to examine the psychometric integrity and dimensions of the Chinese Happiness Inventory (CHI) in relation to scores on Ryff's Psychological Well-Being Scale among retired older people in Taiwan. A cross-sectional study was carried out at social service centers in Taipei, Taiwan. Retired adults gave informed consent from September to November 2010, and completed a package of structured questionnaires measuring happiness and psychological well-being. Internal consistency, the factor structure of the CHI and criterion validity were assessed. Results from an exploratory factor analysis showed a three-factor solution for the CHI. These factors were named Positive Affect, Life Satisfaction and Interpersonal Relationships. Internal consistency coefficients were 0.95 (Positive Affect), 0.91 (Life Satisfaction), 0.85 (Interpersonal Relationships) and 0.97 (total scale). The results of a canonical correlation analysis showed the presence of a strong relationship between CHI and Ryff's Psychological Well-Being Scale (r = 0.69), and that two canonical variates could be derived from the relationship between them. The results show that the CHI is a three-dimensional scale with high reliability and validity. The construct of happiness emphasizes relationships in relation to others and environment rather than autonomy in this sample. Although the components of happiness might be similar for Positive Affect and Life Satisfaction, their weights for Interpersonal Relationships should be considered when measuring happiness in different cultures.

    This book provides the presentation of the motion of pure nonlinear oscillatory systems and various solution procedures which give the approximate solutions of the strong nonlinear oscillator equations. The book presents the original author’s method for the analytical solution procedure of the pure nonlinear oscillator system. After an introduction, the physical explanation of the pure nonlinearity and of the pure nonlinear oscillator is given. The analytical solution for free and forced vibrations of the one-degree-of-freedom strong nonlinear system with constant and time variable parameter is considered. Special attention is given to the one and two mass oscillatory systems with two-degrees-of-freedom. The criteria for the deterministic chaos in ideal and non-ideal pure nonlinear oscillators are derived analytically. The method for suppressing chaos is developed. Important problems are discussed in didactic exercises. The book is self-consistent and suitable as a textbook for students and also for profess...

    A common feature of many string-motivated particle physics models is additional strongly coupled U (1 )'s. In such sectors, electric and magnetic states have comparable mass, and integrating out modes also charged under U (1 ) hypercharge generically yields C P preserving electric kinetic mixing and C P violating magnetic kinetic mixing terms. Even though these extra sectors are strongly coupled, we show that in the limit where the extra sector has approximate N =2 supersymmetry, we can use formal methods from Seiberg-Witten theory to compute these couplings. We also calculate various quantities of phenomenological interest such as the cross section for scattering between visible sector states and heavy extra sector states as well as the effects of supersymmetry breaking induced from coupling to the minimal supersymmetric Standard Model.

    The continuous evolution and development of experimental techniques is at the basis of any fundamental achievement in modern physics. Strongly correlated systems (SCS), more than any other, need to be investigated through the greatest variety of experimental techniques in order to unveil and crosscheck the numerous and puzzling anomalous behaviors characterizing them. The study of SCS fostered the improvement of many old experimental techniques, but also the advent of many new ones just invented in order to analyze the complex behaviors of these systems. Many novel materials, with functional properties emerging from macroscopic quantum behaviors at the frontier of modern research in physics, chemistry and materials science, belong to this class of systems. The volume presents a representative collection of the modern experimental techniques specifically tailored for the analysis of strongly correlated systems. Any technique is presented in great detail by its own inventor or by one of the world-wide recognize...

    We show that the fermion mass spectrum may naturally be understood in terms of flavour democratic fixed points in supersymmetric theories which have a large domain of attraction in the presence of "strong unification". Our approach provides an alternative to the approximate Yukawa texture zeroes of the Froggatt-Nielsen mechanism. We discuss a particular model based on a broken gauged $SU(3)_L\\times SU(3)_R$ family symmetry which illustrates our approach.

    The size of micromagnetic structures, such as domain walls or vortices, is comparable to the exchange length of the ferromagnet. Both, the exchange length of the stray field l{sub s} and the magnetocrystalline exchange length l{sub k}, are material-dependent quantities that usually lie in the nanometer range. This emphasizes the theoretical challenges associated with the mesoscopic nature of micromagnetism: the magnetic structures are much larger than the atomic lattice constant, but at the same time much smaller than the sample size. In computer simulations, the smallest exchange length serves as an estimate for the largest cell size admissible to prevent appreciable discretization errors. This general rule is not valid in special situations where the magnetization becomes particularly inhomogeneous. When such strongly inhomogeneous structures develop, micromagnetic simulations inevitably contain systematic and numerical errors. It is suggested to combine micromagnetic theory with a Heisenberg model to resolve such problems. We analyze cases where strongly inhomogeneous structures pose limits to standard micromagnetic simulations, arising from fundamental aspects as well as from numerical drawbacks. - Highlights: • We discuss the impact of strong inhomogeneities on micromagnetic simulations. • Analysis of fundamental and numerical errors in micromagnetic point singularities. • Numerical and methodological errors in exchange energy terms are quantified. • Suggestion to combine atomistic Heisenberg models with micromagnetism in such cases.

    Introduction. Questionnaires on Functional Health Status (FHS) are part of the assessment of oropharyngeal dysphagia. Objective. To conduct a systematic review of the literature on the psychometric properties of English-language FHS questionnaires in adults with oropharyngeal dysphagia. Methods. A systematic search was performed using the electronic databases Pubmed and Embase. The psychometric properties of the questionnaires were determined based on the COSMIN taxonomy of measurement properties and definitions for health-related patient-reported outcomes and the COSMIN checklist using preset psychometric criteria. Results. Three questionnaires were included: the Eating Assessment Tool (EAT-10), the Swallowing Outcome after Laryngectomy (SOAL), and the Self-report Symptom Inventory. The Sydney Swallow Questionnaire (SSQ) proved to be identical to the Modified Self-report Symptom Inventory. All FHS questionnaires obtained poor overall methodological quality scores for most measurement properties. Conclusions. The retrieved FHS questionnaires need psychometric reevaluation; if the overall methodological quality shows satisfactory improvement on most measurement properties, the use of the questionnaires in daily clinic and research can be justified. However, in case of insufficient validity and/or reliability scores, new FHS questionnaires need to be developed using and reporting on preestablished psychometric criteria as recommended in literature.

    To review systematically the psychometric properties of balance measures for use in people with cerebellar ataxia. Medline, AMED, CINAHL, Web of Science and EMBASE were searched between 1946 and April 2014. Two reviewers independently searched data sources. Cerebellar-specific and generic measures of balance were considered. Included studies tested psychometric properties of balance measures in people with cerebellar ataxia of any cause. Quality of reported studies was rated using the Consensus Based Standards for the selection of health status Measurement INstruments (COSMIN) checklist. Twenty-one articles across which 16 measures had been tested were included for review. Using the COSMIN, quality of methodology in studies investigating psychometric properties of generic balance measures (n=10) was rated predominantly as 'poor'. Furthermore, responsiveness has not been tested for any generic measures in this population. The quality of studies investigating psychometric properties of balance sub-components of the cerebellar-specific measures (n=6) ranged from 'poor' to 'excellent'; however, Minimally Clinically Important Difference has not been determined for these cerebellar-specific measures. The Posture and Gait (PG) sub-component of the International Cooperative Ataxia Rating Scale (ICARS) demonstrates the most robust psychometric properties with acceptable clinical utility. © The Author(s) 2014.

    The aim of this study was to test psychometrically the Italian and French versions of the Care Dependency Scale. The Care Dependency Scale assesses changes in patients' level of care dependency including important functional and mental dimensions. Evaluation of the psychometric properties of the Italian version is still ongoing. The French version has to date not been validated. Nationwide cross-sectional point prevalence study. Data were extracted from the national, annual prevalence survey of hospital-acquired pressure ulcers and inpatient falls in Swiss acute care hospitals in 2011. A total of 799 Italian and 1068 French-speaking patients were included in the analysis. For the evaluation, the psychometric properties were tested for each language both separately and conjointly. The scales revealed high internal consistency. Factor analysis presented a one-factor solution for both versions separately as well as combined. Comparison of internal structure revealed an excellent degree of equivalence between the versions. Highly significant Spearman correlations between the Care Dependency Scale and the Braden Scale sum scores indicated satisfactory criterion validity. Both the Italian and the French versions of the Care Dependency Scale showed satisfactory psychometric properties and a high level of equivalence. Further psychometric testing, using modern test theory approaches, is required. However, the scale is recommended as a valid instrument for further use in Italian and French. © 2016 John Wiley & Sons Ltd.

  16. Disordered strongly correlated electronic systems

    Javan Mard, Hossein

    Disorder can have a vast variety of consequences for the physics of phase transitions. Some transitions remain unchanged in the presence of disorder while others are completely destroyed. In this dissertation we study the effects of quenched disorder on electronic systmens at zero temperature. First, we perform variational studies of the interaction-localization problem to describe the interaction-induced renormalizations of the effective (screened) random potential seen by quasiparticles. Here we present results of careful finite-size scaling studies for the conductance of disordered Hubbard chains at half-filling and zero temperature. While our results indicate that quasiparticle wave functions remain exponentially localized even in the presence of moderate to strong repulsive interactions, we show that interactions produce a strong decrease of the characteristic conductance scale g* signaling the crossover to strong localization. This effect, which cannot be captured by a simple renormalization of the disorder strength, instead reflects a peculiar non-Gaussian form of the spatial correlations of the screened disordered potential, a hitherto neglected mechanism to dramatically reduce the impact of Anderson localization (interference) effects. Second, we formulate a strong-disorder renormalization-group (SDRG) approach to study the beta function of the tight-binding model in one dimension with both diagonal and off-diagonal disorder for states at the band center. We show that the SDRG method, when used to compute transport properties, yields exact results since it is identical to the transfer matrix method. The beta function is shown to be universal when only off-diagonal disorder is present even though single-parameter scaling is known to be violated. A different single-parameter scaling theory is formulated for this particular (particle-hole symmetric) case. Upon breaking particle-hole symmetry (by adding diagonal disorder), the beta function is shown to

    Full Text Available Introduction. There have been no scales specifically developed to assess physician-patient communication behaviors (PPCB in the sub-Saharan population. Aim. We revised an existing PPCB scale and tested its psychometric properties for HIV patients in Kenya. Methods. 17 items (five-point scale measuring PPCB were initially adopted from the Matched Pair Instrument (MPI. Between July and August 2011, we surveyed a convenient sample of 400 HIV adult patients, attending three Academic Model Providing Healthcare program (AMPATH clinics in Eldoret, Kenya. Of these 400, eight also participated in cognitive interviews, and 200 were invited to return after one week for follow-up interviews; 134 (67% returned and were interviewed. Construct and content validity were established using an exploratory factor analysis, bivariate analyses, internal consistency, test-retest reliability and cognitive interviews. Results. Construct and content validity supported a one-dimensional measure of 13 PPCB items. Items assessed physicians’ effort to promote a favorable atmosphere for interaction with HIV patients. Biases associated with encoding and comprehension of specific terms, such as “discussion, involvement or concerns,” were noted. Internal consistency (Cronbach’s alpha = .81 and one-week retest reliability scores (.82 supported the reliability of the 13-item scale. Discussion. The revised PPCB scale showed acceptable validity and reliability in Kenya.

    This special section is dedicated to the Strongly Correlated Electron Systems Conference (SCES) 2011, which was held from 29 August-3 September 2011, in Cambridge, UK. SCES'2011 is dedicated to 100 years of superconductivity and covers a range of topics in the area of strongly correlated systems. The correlated electronic and magnetic materials featured include f-electron based heavy fermion intermetallics and d-electron based transition metal compounds. The selected papers derived from invited presentations seek to deepen our understanding of the rich physical phenomena that arise from correlation effects. The focus is on quantum phase transitions, non-Fermi liquid phenomena, quantum magnetism, unconventional superconductivity and metal-insulator transitions. Both experimental and theoretical work is presented. Based on fundamental advances in the understanding of electronic materials, much of 20th century materials physics was driven by miniaturisation and integration in the electronics industry to the current generation of nanometre scale devices. The achievements of this industry have brought unprecedented advances to society and well-being, and no doubt there is much further to go—note that this progress is founded on investments and studies in the fundamentals of condensed matter physics from more than 50 years ago. Nevertheless, the defining challenges for the 21st century will lie in the discovery in science, and deployment through engineering, of technologies that can deliver the scale needed to have an impact on the sustainability agenda. Thus the big developments in nanotechnology may lie not in the pursuit of yet smaller transistors, but in the design of new structures that can revolutionise the performance of solar cells, batteries, fuel cells, light-weight structural materials, refrigeration, water purification, etc. The science presented in the papers of this special section also highlights the underlying interest in energy-dense materials, which

    Metacognition describes the process of thinking about one's own thought processes. This concept was introduced by Flavell in 1979 and has since been widely developed in the cognitive approach to mood and anxiety disorders. As it happens, many recent studies have underlined the links between metacognition and anxio-depressive symptoms, pointing out the interest of assessing its various dimensions. The short form of the Metacognitions Questionnaire is a brief multidimensional measure of a range of metacognitive processes and metacognitive beliefs about worry and cognition relevant to the vulnerability to and the maintenance of emotional disorders. The aim of this study was twofold: firstly to adapt and validate a French version of the short form of the Metacognitions Questionnaire (MCQ-30) and to assess its psychometric properties in a clinical sample, and secondly to investigate metacognitive predictors of anxiety and depression in this sample. The sample included 55 clinical participants (24 men, 31 women, mean age=51.33±14.62) with DSM-IV-TR psychiatric disorders (major depression, bipolar disorder and obsessive-compulsive disorder). Instrument reliability (internal consistency), construct validity (confirmatory factor analysis), and convergent validity were measured. The total score and the five subscale scores were also compared with previous results in non-clinical samples. Reliability analyses indicated that the French version of the MCQ-30 possessed satisfactory internal consistency (Cronbach α=0.84), and confirmatory factor analysis supported the MCQ's original five-factor structure. Correlation with measurements of depression, anxiety and pathological worry demonstrated convergent validity (r=0.62, Pmetacognition, in relation to the anxio-depressive symptomatology and the subsequent management of patients.

    Work Positive is Ireland's national policy initiative to control work-related stress. Since the introduction of the UK Health and Safety Executive's Management Standards (MS) in 2004, a number of studies have been undertaken to assess the potential adaptation of the MS framework within Ireland. To investigate the dimensionality, reliability and validity of the Irish version of the MS Indicator Tool (ROI-MSIT). Between February 2011 and June 2014, we collected data from a wide range of public and private sector organizations that used the ROI-MSIT. In addition to the ROI-MSIT, respondents completed the WHO-Five Well-being Index (WHO-5). Exploratory factor analysis (EFA) was used to determine whether the ROI-MSIT maintained the structure of the UK instrument. The internal consistency of the ROI-MSIT was also assessed to determine its reliability, while its criterion-related validity was explored through correlation analysis with the WHO-5. Data were collected from 7377 participants. The factor structure of the ROI-MSIT consisted of six factors; the Demands, Control, Peer Support, Relationships and Role factors were equivalent to the original UK factors. Like the Italian version, a principal factor emerged that combined the Manager Support and Change domains. Cronbach's alpha scores ranged from 0.75 to 0.91. Finally, the ROI-MSIT's subscales and WHO-5 were positively correlated (r = 0.42-0.59, P psychometric evaluation of the ROI-MSIT is recommended. © The Author 2016.

    2013-01-01

    This paper reports the development and psychometric testing of the Ascent to Competence Scale, an instrument designed to measure nursing students' perceptions of the quality of their clinical placement experience. The key purpose of clinical placements is to facilitate students' learning and progress toward the attainment of competence. The attainment of competence requires personal commitment and active involvement of students; support and guidance of clinical and academic staff; and clinical environments that are welcoming and inclusive of students. The items for the Ascent to Competence Scale were identified following a critical review of the literature. Content and face validity were established by an expert panel. During 2010 the instrument was tested with third year nursing students (n=88) from one Australian university. Exploratory factor analysis with promax oblique rotation was used to determine construct validity and Cronbach's coefficient alpha determined the scale's internal consistency reliability. The final scale demonstrated satisfactory internal consistency (alpha 0.98). Exploratory factor analysis yielded a three-component structure termed "Being welcomed"; "Belongingness" and "Learning and competence". Each subscale demonstrated high internal consistency: 0.89; 0.96; and 0.95 respectively. The Ascent to Competence Scale provides a fresh perspective on clinical placements as it allows for the relationship between belongingness, learning and competence to be explored. The scale was reliable and valid for this cohort. Further research in different contexts would be valuable in extending upon this work. The Ascent to Competence Scale profiled in this paper will be of benefit to both educational and healthcare institutions. The use of a quantified yardstick, such as the Ascent to Competence Scale, is important in evaluating the efficacy of programs, placements and partnerships between higher education and health services.

    Alarm fatigue can adversely affect nurses' efficiency and concentration on their tasks, which is a threat to patients' safety. The purpose of the present study was to develop and test the psychometric accuracy of an alarm fatigue questionnaire for nurses. This study was conducted in two stages: in stage one, in order to establish the different aspects of the concept of alarm fatigue, the researchers reviewed the available literature-articles and books-on alarm fatigue, and then consulted several experts in a meeting to define alarm fatigue and develop statements for the questionnaire. In stage two, after the final draft had been approved, the validity of the instrument was measured using the two methods of face validity (the quantitative and qualitative approaches) and content validity (the qualitative and quantitative approaches). Test-retest, Cronbach's alpha, and Principal Component Analysis were used for item reduction and reliability analysis. Based on the results of stage one, the researchers extracted 30 statements based on a 5-point Likert scale. In stage two, after the face and content validity of the questionnaire had been established, 19 statements were left in the instrument. Based on factor loadings of the items and "alpha if item deleted" and after the second round of consultation with the expert panel, six items were removed from the scale. The test of the reliability of nurses' alarm fatigue questionnaire based on the internal homogeneity and retest methods yielded the following results: test-retest correlation coefficient = 0.99; Guttman split-half correlation coefficient = 0.79; Cronbach's alpha = 0.91. Regarding the importance of recognizing alarm fatigue in nurses, there is need for an instrument to measure the phenomenon. The results of the study show that the developed questionnaire is valid and reliable enough for measuring alarm fatigue in nurses.

    To describe the development and psychometric testing of the Supportive Supervisory Scale (SSS). The development of the items of the scale was based on Winnicott's relationship theory and on focus groups with 26 healthcare aides (HCAs) and 30 supervisors from six long-term care (LTC) facilities in Ontario, Canada. Content validity of the 15-item instrument was established by a panel of experts. Based on a secondary analysis of data collected from 222 HCAs in 10 LTC facilities in Ontario, Canada, the SSS was subjected to principal components analysis with oblique rotation. A two-factor solution was accepted, which is consistent with the theoretical conceptualization of the instrument. Factor I was labeled Respects Uniqueness and Factor II was labeled Being Reliable. Internal consistency of Factor I was .95, and that of Factor II was .91. Discriminant validity was also established. The focus groups revealed that "being available to staff" while "recognizing the HCA as an individual, and taking a moment to get to know them" was essential to feeling supported by their supervisor. The SSS is a reliable and valid measure of supervisory support of supervisors working in LTC facilities. At the core of supportive supervision is the supervisor's ability to develop and maintain positive relationships with each HCA. It is through respecting the uniqueness of each HCA and being reliable that supervisor-HCA relationships can flourish. Supportive leadership in LTC settings is a major contributor to HCAs' job satisfaction and retention and to quality of patient care. Therefore, a tool developed and tested to measure supervisors' supportive capacities in LTC is primal to evaluate the effectiveness of supervisors in these environments.

    Full Text Available Background: During the past several years, there has been a growing interest in the negative effects that providing therapy may have on therapists. Of special interest is a phenomenon called secondary traumatization, which can arise while working with traumatized clients. To develop a simple screening tool for secondary traumatization, a quantitative assessment instrument was constructed using a data-driven approach based on qualitative interviews with affected trauma therapists as well as experienced supervisors in trauma therapy. Objective: The aim of the current study was to analyze the psychometric properties of the newly developed Questionnaire for Secondary Traumatization (FST acute and lifetime version and to determine the most appropriate scoring procedure. Method: To this end, three independent samples of psychotherapists (n=371, trauma therapists in training (n=80, and refugee counselors (n=197 filled out an online questionnaire battery. Data structure was analyzed using factor analyses, cluster analyses, and reliability analyses. Results: Factor analyses yielded a six-factor structure for both the acute and the lifetime version with only a small number of items loading on differing factors. Cluster analyses suggested a single scale structure of the questionnaire. The FST total score showed good internal consistencies across all three samples, while internal consistency of the six extracted factors was mixed. Conclusion: With the FST, a reliable screening instrument for acute and lifetime secondary traumatization is now available which is free of charge and yields a sum score for quick evaluation. The six-factor structure needs to be verified with confirmatory factor analyses.

    Full Text Available Abstract Objectives Measurement of treatment satisfaction in diabetes is important as it has been shown to be associated with positive outcomes, reduced disease cost and better health. The aim of this study was to assess the construct validity and internal consistency reliability of the Greek version of the Diabetes Treatment Satisfaction Questionnaire (DTSQ. Methods A sample of type II diabetes patients (N = 172 completed the DTSQ status version, the SF-36 health survey and also provided data regarding treatment method, clinical and socio-demographic status. Instrument structure, reliability (Cronbach's a and construct validity (convergent, discriminative, concurrent and known-groups were assessed. Results The DTSQ measurement properties were confirmed in the Greek version with confirmatory factor analysis (CFA. Scale reliability was high (Cronbach's a = 0.92. Item-scale internal consistency and discriminant validity were also good, exceeding the designated success criteria. Significant correlations were observed between DTSQ items/overall score and SF-36 scales/component scores, which were hypothesized to measure similar dimensions. Known groups' comparisons yielded consistent support of the construct validity of the instrument. Conclusions The instrument was well-accepted by the patients and its psychometric properties were similar to those reported in validation studies of other language versions. Further research, incorporating a longitudinal study design, is required for examining test-retest reliability and responsiveness of the instrument, which were not addressed in this study. Overall, the present results confirm that the DTSQ status version is a reasonable choice for measuring diabetes treatment satisfaction in Greece.

    In the presence of approximate global symmetries that forbid relevant interactions, strongly coupled light Dark Matter (DM) can appear weakly coupled at small-energy and generate a sizable relic abundance. Fundamental principles like unitarity restrict these symmetries to a small class, where the leading interactions are captured by effective operators up to dimension-8. Chiral symmetry, spontaneously broken global symmetries and non-linearly realized supersymmetry are examples of this. Their DM candidates (composite fermions, pseudo-Nambu-Goldstone Bosons and Goldstini) are interesting targets for LHC missing-energy searches.

    The scalar strong interaction hadron theory, SSI, is a first principles' and nonlocal theory at quantum mechanical level that provides an alternative to low energy QCD and Higgs related part of the standard model. The quark-quark interaction is scalar rather than color-vectorial. A set of equations of motion for mesons and another set for baryons have been constructed. This book provides an account of the present state of a theory supposedly still at its early stage of development. This work will facilitate researchers interested in entering into this field and serve as a basis for possible future development of this theory.

    In this paper we present Hilbert-style axiomatizations for three logics for reasoning about continuous-space Markov processes (MPs): (i) a logic for MPs defined for probability distributions on measurable state spaces, (ii) a logic for MPs defined for sub-probability distributions and (iii) a logic...... defined for arbitrary distributions. These logics are not compact so one needs infinitary rules in order to obtain strong completeness results. We propose a new infinitary rule that replaces the so-called Countable Additivity Rule (CAR) currently used in the literature to address the problem of proving...

    The Family Attitude Scale (FAS) is a self-report measure of critical or hostile attitudes and behaviors towards another family member, and demonstrates an ability to predict relapse in psychoses. Data are not currently available on a French version of the scale. The present study developed a French version of the FAS, using a large general population sample to test its internal structure, criterion validity and relationships with the respondents' symptoms and psychiatric diagnoses, and examined the reciprocity of FAS ratings by respondents and their partners. A total of 2072 adults from an urban population undertook a diagnostic interview and completed self-report measures, including an FAS about their partner. A subset of participants had partners who also completed the FAS. Confirmatory factor analyses revealed an excellent fit by a single-factor model, and the FAS demonstrated a strong association with dyadic adjustment. FAS scores of respondents were affected by their anxiety levels and mood, alcohol and anxiety diagnoses, and moderate reciprocity of attitudes and behaviors between the partners was seen. The French version of the FAS has similarly strong psychometric properties to the original English version. Future research should assess the ability of the French FAS to predict relapse of psychiatric disorders. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The Beck Depression Inventory (BDI) is perhaps the most commonly used screening instrument for depression in the general population. We examined the psychometric properties of a Persian-language version of the second edition of this instrument (BDI-II) [Beck et al., 1996] in an Iranian college-student sample. In a sample of 125 student volunteers from two Iranian universities, we compared mean item scores on the BDI-II-Persian with those on the English-language version administered to North American college students, and assessed internal consistency and test-retest reliability of the BDI-II-Persian and its concurrent validity against a measure of negative automatic thoughts in depression, the Automatic Thoughts Questionnaire [Hollon and Kendall, 1980]. We also examined the factor structure of the BDI-II-Persian through comparing the fit of various proposed models to the data using confirmatory factor analysis. The BDI-II-Persian had high internal consistency (Cronbach's alpha=0.87) and acceptable test-retest reliability (r=0.74). The instrument correlated strongly with the Automatic Thoughts Questionnaire. In factor analysis, models with strongly correlated affective-cognitive and somatic-vegetative factors provided a better fit than models with one global factor. These data support the reliability and concurrent validity of the BDI-II-Persian as a measure of depressive symptoms in nonclinical samples. (c) 2005 Wiley-Liss, Inc.

    To investigate the psychometric properties of the Geriatric Suicide Ideation Scale (GSIS) among community-residing older adults. We recruited 173 voluntary participants, 65 years and older, into a 2+ year longitudinal study of the onset or exacerbation of depressive symptoms and suicide ideation. We assessed the internal consistency of the GSIS and its four component subscales, and its shorter and longer duration test-retest reliability, convergent (depression, social hopelessness, and loneliness), divergent (psychological well-being, life satisfaction, perceived social support, and self-rated health), discriminant (basic and instrumental activities of daily living and social desirability), criterion (history of suicide behavior), and predictive validity (future suicide ideation). The GSIS demonstrated strong test-retest reliability and internal consistency. Baseline GSIS scores were significantly positively associated with suicide risk factors, negatively associated with potential resiliency factors, and not associated with functional impairment or social desirability. GSIS scores significantly differentiated between participants with as compared to those without a history of suicide behavior. Baseline GSIS scores significantly predicted suicide ideation at a 2+ year follow-up assessment. Findings suggest strong measurement characteristics for the GSIS with community-residing older adults, including impressive consistency over time. These results are consistent with research attesting to the empirical and pragmatic strengths of this measure. These findings have implications for the monitoring of suicide risk when aiming to enhance mental health and well-being and prevent suicide in later life.

    This paper presents the main lines of the design and the findings of a reception study on news comprehension. This empirical study is a comparison of the comprehension processes of Danes and French Canadians over a set of news texts from both countries. Comprehension is explored from a cultural...... perspective, through the lens of cognition and pragmatics, revealing the role played by cultural knowledge in comprehension and the underlying relationship between a text and its intended audience. It is argued that recipients ‘problematise’ the news texts, a process by which the texts answer questions...... that take their roots in the cultural knowledge of the recipients....

    Dovey, Terence M; Aldridge, Victoria K; Martin, Clarissa I; Wilken, Markus; Meyer, Caroline

    2016-12-01

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

    The purpose of the study was to undertake rigorous psychometric testing of the Caring Efficacy Scale in a sample of Registered Nurses. A cross-sectional survey of 2000 registered nurses was undertaken. The Caring Efficacy Scale was utilized to inform the psychometric properties of the selected items of the Caring Efficacy Scale. Cronbach's Alpha identified reliability of the data. Exploratory Factor Analysis and Confirmatory Factor Analysis were undertaken to validate the factors. Confirmatory factor analysis confirmed the development of two factors; Confidence to Care and Doubts and Concerns. The Caring Efficacy Scale has undergone rigorous psychometric testing, affording evidence of internal consistency and goodness-of-fit indices within satisfactory ranges. The Caring Efficacy Scale is valid for use in an Australian population of registered nurses. The scale can be used as a subscale or total score reflective of self-efficacy in nursing. This scale may assist nursing educators to predict levels of caring efficacy.
