The role of psychological and biological factors in postinfective gut dysfunction. (1/6813)

BACKGROUND: Both psychological and physiological disturbances have been implicated in the aetiopathogenesis of irritable bowel syndrome (IBS). AIMS: To investigate how the psychological factors act, and the involvement of infective and physiological factors. METHODS: Consecutive patients hospitalised for gastroenteritis reported life events for the previous 12 months, and past illness experiences on standardised questionnaires. They also completed psychometric questionnaires for anxiety, neuroticism, somatisation, and hypochondriasis. In some patients, rectal biopsy specimens were obtained during the acute illness and at three months postinfection. RESULTS: Ninety four patients completed all questionnaires: 22 patients were diagnosed with IBS after their gastroenteritis (IBS+), and 72 patients returned to normal bowel habits (IBS-). IBS+ patients reported more life events and had higher hypochondriasis scores than IBS- patients. The predictive value of the life event and hypochondriasis measures was highly significant and independent of anxiety, neuroticism, and somatisation scores, which were also elevated in IBS+ patients. Rectal biopsy specimens from 29 patients showed a chronic inflammatory response in both IBS+ and IBS- patients. Three months later, specimens from IBS+ patients continued to show increased chronic inflammatory cell counts but those from IBS- patients had returned to normal levels. IBS+ and IBS- patients exhibited rectal hypersensitivity and hyper-reactivity and rapid colonic transit compared with normal controls, but there were no significant differences between IBS+ and IBS- patients for these physiological measurements. CONCLUSION: Psychological factors most clearly predict the development of IBS symptoms after gastroenteritis but biological mechanisms also contribute towards the expression of symptoms.  (+info)

Development of the physical therapy outpatient satisfaction survey (PTOPS). (2/6813)

BACKGROUND AND PURPOSE: The purposes of this 3-phase study were (1) to identify the underlying components of outpatient satisfaction in physical therapy and (2) to develop a test that would yield reliable and valid measurements of these components. SUBJECTS: Three samples, consisting of 177, 257, and 173 outpatients from 21 facilities, were used in phases 1, 2, and 3, respectively. METHODS AND RESULTS: In phase 1, principal component analyses (PCAs), reliability checks, and correlations with social desirability scales were used to reduce a pool of 98 items to 32 items. These analyses identified a 5-component model of outpatient satisfaction in physical therapy. The phase 2 PCA, with a revised pool of 48 items, indicated that 4 components rather than 5 components represented the best model and resulted in the 34-item Physical Therapy Outpatient Satisfaction Survey (PTOPS). Factor analyses conducted with phase 2 and phase 3 data supported this conclusion and provided evidence for the internal validity of the PTOPS scores. The 4-component scales were labeled "Enhancers," "Detractors," "Location," and "Cost." Responses from subsamples of phase 3 subjects provided evidence for validity of scores in that the PTOPS components of "Enhancers," "Detractors," and "Cost" appeared to differentiate overtly satisfied patients from overtly dissatisfied patients. "Location" and "Enhancer" scores discriminated subjects with excellent attendance at scheduled physical therapy sessions from those with poor attendance. CONCLUSION AND DISCUSSION: In this study, we identified components of outpatient satisfaction in physical therapy and used them to develop a test that would yield valid and reliable measurements of these components.  (+info)

The psychometric properties of clinical rating scales used in multiple sclerosis. (3/6813)

OullII;l y Many clinical rating scales have been proposed to assess the impact of multiple sclerosis on patients, but only few have been evaluated formally for reliability, validity and responsiveness. We assessed the psychometric properties of five commonly used scales in multiple sclerosis, the Expanded Disability Status Scale (EDSS), the Scripps Neurological Rating Scale (SNRS), the Functional Independence Measure (FIM), the Ambulation Index (AI) and the Cambridge Multiple Sclerosis Basic Score (CAMBS). The score frequency distributions of all five scales were either bimodal (EDSS and AI) or severely skewed (SNRS, FIM and CAMBS). The reliability of each scale depended on the definition of 'agreement'. Inter-and intra-rater reliabilities were high when 'agreement' was considered to exist despite a difference of up to 1.0 EDSS point (two 0.5 steps), 13 SNRS points, 9 FIM points, 1 AI point and 1 point on the various CAMBS domains. The FIM, AI, and the relapse and progression domains of the CAMBS were sensitive to clinical change, but the EDSS and the SNRS were unresponsive. The validity of these scales as impairment (SNRS and EDSS) and disability (EDSS, FIM, AI and the disability domain of the CAMBS) measures was established. All scales correlated closely with other measures of handicap and quality of life. None of these scales satisfied the psychometric requirements of outcome measures completely, but each had some desirable properties. The SNRS and the EDSS were reliable and valid measures of impairment and disability, but they were unresponsive. The FIM was a reliable, valid and responsive measure of disability, but it is cumbersome to administer and has a limited content validity. The AI was a reliable and valid ambulation-related disability scale, but it was weakly responsive. The CAMBS was a reliable (all four domains) and responsive (relapse and progression domains) outcome measure, but had a limited validity (handicap domain). These psychometric properties should be considered when designing further clinical trials in multiple sclerosis.  (+info)

Impairment in preattentive visual processing in patients with Parkinson's disease. (4/6813)

We explored the possibility of whether preattentive visual processing is impaired in Parkinson's disease. With this aim, visual discrimination thresholds for orientation texture stimuli were determined in two separate measurement sessions in 16 patients with idiopathic Parkinson's disease. The results were compared with those of 16 control subjects age-matched and 16 young healthy volunteers. Discrimination thresholds were measured in a four-alternative spatial forced-choice paradigm, in which subjects judged the location of a target embedded in a background of distractors. Four different stimulus configurations were employed: (i) a group of vertical targets among horizontal distractors ('vertical line targets'); (ii) targets with varying levels of orientation difference on a background of spatially filtered vertically oriented noise ('Gaussian filtered noise'); (iii) one 'L' among 43 '+' signs ('texton'), all of which assess preattentive visual processing; and (iv) control condition, of one 'L' among 43 'T' distractors ('non-texton' search target), which reflects attentive visual processing. In two of the preattentive tasks (filtered noise and texton), patients with Parkinson's disease required significantly greater orientation differences and longer stimulus durations, respectively. In contrast, their performance in the vertical line target and non-texton search target was comparable to that of the matched control subjects. These differences were more pronounced in the first compared with the second session. Duration of illness and age within the patient group correlated significantly with test performance. In all conditions tested, the young control subjects performed significantly better than the more elderly control group, further indicating an effect of age on this form of visual processing. The results suggest that, in addition to the well documented impairment in retinal processing, idiopathic Parkinson's disease is associated with a deficit in preattentive cortical visual processing.  (+info)

Validation of a specific quality of life questionnaire for functional digestive disorders. (5/6813)

BACKGROUND: Dyspepsia and irritable bowel syndrome are suitable conditions for assessment of quality of life. Their similarities justify the elaboration of a single specific questionnaire for the two conditions. AIMS: To examine the process leading to the validation of the psychometric properties of the functional digestive disorders quality of life questionnaire (FDDQL). METHODS: Initially, the questionnaire was given to 154 patients, to assess its acceptability and reproducibility, analyse its content, and reduce the number of items. Its responsiveness was tested during two therapeutic trials which included 428 patients. The questionnaire has been translated into French, English, and German. The psychometric validation study was conducted in France, United Kingdom, and Germany by 187 practitioners. A total of 401 patients with dyspepsia or irritable bowel syndrome, defined by the Rome criteria, filled in the FDDQL and generic SF-36 questionnaires. RESULTS: The structure of the FDDQL scales was checked by factorial analysis. Its reliability was expressed by a Cronbach's alpha coefficient of 0.94. Assessment of its discriminant validity showed that the more severe the functional digestive disorders, the more impaired the quality of life (p<0.05). Concurrent validity was supported by the correlation found between the FDDQL and SF-36 questionnaire scales. The final version of the questionnaire contains 43 items belonging to eight domains. CONCLUSIONS: The properties of the FDDQL questionnaire, available in French, English, and German, make it appropriate for use in clinical trials designed to evaluate its responsiveness to treatment among patients with dyspepsia and irritable bowel syndrome.  (+info)

Measuring therapist technique in psychodynamic psychotherapies. Development and use of a new scale. (6/6813)

Treatment manuals are becoming a requirement for conducting quality psychotherapy research. What the field lacks, however, are reliable, valid, and cost-efficient instruments that can be used to measure a wide variety of prescribed therapeutic techniques. This article describes the development and use of a new instrument, the Interpretive and Supportive Technique Scale (ISTS). It is designed to measure interpretive and supportive features of technique for a broad range of dynamically oriented psychotherapies. Data concerning the psychometric properties of the ISTS are presented from two studies. The findings suggest that the ISTS is a potentially useful tool for measuring interventions for different forms of dynamically oriented psychotherapy.  (+info)

Attentional ability among survivors of leukaemia. (7/6813)

Attentional ability in 19 survivors of acute lymphoblastic leukaemia and 19 sibling controls was assessed using a neuropsychological model of attention. Analysis revealed that children who had received treatment for leukaemia exhibited significantly poorer performance on measures of the "focus encode" and "focus execute" elements of attention and on measures of the ability to respond to external cues and feedback. No significant differences in performance were found for measures of sustained attention and the ability to shift attention. These results indicate that children who have received treatment for leukaemia may experience highly specific attentional deficits that could have an impact on academic performance, particularly mathematical and reading skills. It is suggested that this underlying attentional deficit might be the source of the neuropsychological sequelae associated with the disease. Future attempts at remediation should incorporate activities specifically designed to ameliorate focusing difficulties.  (+info)

Race in the "decade of the brain". (8/6813)

Despite NIMH efforts to facilitate the study of women and minorities in federally funded schizophrenia research, there is a significant lack of information about race differences in brain morphology and neuropsychological function in schizophrenia. A review of three major psychiatric journals between 1994 and 1996 revealed that only 14 (2.8%) of 502 schizophrenia articles reported the results of race analyses. Only 84 (16.7%) even reported the racial composition of the study sample. The study of race differences in schizophrenia, although fraught with methodological complexity and social/political tension, is necessary to prevent inappropriate generalization of research results across racial groups.  (+info)

Objective To test psychometrics of the Short Form 36 Health Survey version 2 (SF-36v2) and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0) in Chinese mainland patients with methadone maintenance treatment (MMT). Methods A total of 1,212 patients were recruited from two MMT clinics in Xian, China. Reliability was estimated with Cronbachs α and intra-class correlation (ICC). Convergent and discriminant validity was assessed using multitrait-multimethod correlation matrix. Sensitivity was measured with ANOVA and relative efficiency. Responsiveness was evaluated by pre-post paired-samples t-test and standardized response mean based on the patients health status changes following 6-month period. Results Cronbachs α of the SF-36v2 physical and mental summary components were 0.80 and 0.86 (eight scales range 0.73-0.92) and the QOL-DAv2.0 was 0.96 (four scales range: 0.80-0.93). ICC of the SF-36v2 two components were 0.86 and 0.85 (eight scales range: 0.72-0.87) and the QOL-DAv2.0 was 0.94 (four
Evidence-based assessment of the psychometric properties of available paediatric sleep instruments is needed (Lewandowski et al., 2011; Spruyt and Gozal, 2011). The current study examined the factor structure, internal consistency reliability and concurrent validity of the ASHS using a community-based urban sample of 16-19-year-old adolescents. The empirical factor structure of the revised 24-item scale (ASHSr) is largely consistent with the theoretically based structure proposed initially (LeBourgeois et al., 2005), with the exceptions that the cognitive and emotional domains were combined into one factor and a new behavioural arousal construct was identified. Internal consistency reliability of the ASHSr as well as concurrent validity with objective measures of sleep and convergent validity with behavioural outcomes indicate that the ASHSr has satisfactory psychometric properties for a research instrument to assess adolescent sleep hygiene.. Sleep hygiene was correlated modestly with objective ...

Results: Rasch analysis was used to refine the SPaRQ. The result was a 19-item measure divided into two subscales. The 9-item Social Behaviors subscale measured difficulties with performing actions in a social context due to hearing loss. The 10-item Social Perceptions subscale measured negative thoughts and feelings experienced in a social context due to hearing loss. Both Rasch analysis and the traditional psychometric analysis techniques demonstrated that each subscale had strong psychometric properties. In particular, each subscale passed the test of unidimensionality, displayed good fit to the Rasch model, and had high internal consistency. In addition, it was found that, as predicted, each subscale had strong, positive correlations with the hearing-specific questionnaire and moderate, positive correlations with the generic health and disability questionnaire and the depression and anxiety screening questionnaire. Taken together, these findings support the construct validity of the 19-item ...

This study investigated psychometric properties of an instrument for assessing perceived occupational value, the 26-item OVal-pd. Data from 225 Swedish subjects with and without known mental illness were analysed regarding fit to the Rasch measurement model (partial credit model), differential item functioning (DIF), and functioning of the OVal-pd four-category response scale. The reliability (index of person separation, analogous to Cronbachs alpha) was good (0.92) but there were signs of overall and item level (six items) misfit. There was DIF between people with and without mental illness for three items. Iterative deletion of misfitting items resulted in a new 18-item DIF-free scale with good overall and individual item fit and maintained reliability (0.91). There were no disordered response category thresholds. These observations also held true in separate analyses among people with and without mental illness. Thus, the first steps of ensuring that occupational value can be measured in a ...
Key concepts in classical test theory are reliability and validity. A reliable measure is one that measures a construct consistently across time, individuals, and situations. A valid measure is one that measures what it is intended to measure. Reliability is necessary, but not sufficient, for validity. Both reliability and validity can be assessed statistically. Consistency over repeated measures of the same test can be assessed with the Pearson correlation coefficient, and is often called test-retest reliability.[14] Similarly, the equivalence of different versions of the same measure can be indexed by a Pearson correlation, and is called equivalent forms reliability or a similar term.[14] Internal consistency, which addresses the homogeneity of a single test form, may be assessed by correlating performance on two halves of a test, which is termed split-half reliability; the value of this Pearson product-moment correlation coefficient for two half-tests is adjusted with the Spearman-Brown ...

This large national survey of patients with RA or axSpA generated two principal results. First, almost one-fifth (17.2%) of evaluated patients had high fear scores, despite both diseases being typically well managed, and these scores were associated with psychological distress. Thus, the fears identified in this study may reflect psychological distress, and need to be addressed even in patients who have moderate to low disease activity. Second, we have developed the FAIR questionnaire: a disease-specific, psychometrically validated PRO to measure disease and treatment-related fears in patients with RA or axSpA. This instrument demonstrated acceptable psychometric properties: notably unidimensionality, high internal coherence, good discriminant validity and adequate test-retest stability. The FAIR is short (10 items), simple to score and may be a useful tool both in routine practice and clinical trials.. The strengths of this study include the size of the study population, the high level of ...
Using emerging international guidelines, stringent procedures were used to develop and evaluate Canadian-French, German and UK translations/adaptions of the 50 item, parent-completed Child Health Questionnaire (CHQ-PF50). Multitrait analysis was used to evaluate the convergent and discriminant validity of the hypothesized item sets across countries relative to the results obtained for a representative sample of children in the US. Cronbachs alpha coefficient was used to estimate the internal consistency reliability for each of the health scales. Floor and ceiling effects were also examined. Seventy-nine percent of all the item-scale correlations achieved acceptable internal consistency (0.40 or higher). The tests of the item convergent and discriminant validity were successful at least 87% of the time across all scales and countries. Equal item variance was observed 90% of the time across all countries. The reliability coefficients ranged from a low of 0.43 (parental time impact, Canadian English) to a
Item response theory (IRT) is a popular approach used for addressing statistical problems in psychometrics as well as in other fields. The fully Bayesian approach for estimating IRT models is computationally expensive. This limits the use of the procedure in real applications. In an effort to reduce the execution time, a previous study shows that high performance computing provides a solution by achieving a considerable speedup via the use of multiple processors. Given the high data dependencies in a single Markov chain for IRT models, it is not possible to avoid communication overhead among processors. This study is to reduce communication overhead via the use of a row-wise decomposition scheme. The results suggest that the proposed approach increased the speedup and the efficiency for each implementation while minimizing the cost and the total overhead. This further sheds light on developing high performance Gibbs samplers for more complicated IRT models.

Reviews the book, Psychometrics and Psychology by Paul Kline (1979). The author believes that human variation should be studied by analyzing data from psychometric tests usually written multiple-choice tests. Test validity is to be established by the factor structure of tests batteries. Tests are thus validated by their correlation with other tests. Criterion-referenced evaluations, such as studies of contrasts between the scores of reference groups, are seen as suspect. Criterion-referenced tests may provide a description, but because of factor impurity, criterion-referenced tests are not valid scientific instruments. Experimental studies of cognition and personality may complement information gathered from psychometric investigations, but because of their necessarily small sample sizes, such studies are to be regarded as secondary psychometrics. Having thus set the ground rules, Kline presents a cursory discussion of standard test theory. The brevity is unfortunate, because undefined terms ...
The following minimal set of valid health domains for tracking the health of both clinical and general populations has recently been proposed: 1) energy and drive functions, 2) emotional functions, 3) sensation of pain, 4) carrying out daily routine, 5) walking and moving around, and 6) remunerative employment. This study investigates whether these domains can be integrated into a sound psychometric measure to adequately assess, compare, and monitor the health of populations. Data from waves 3 and 4 of the English Longitudinal Study of Ageing (ELSA) were analysed (N = 9779 and 11,050). From ELSA, 12 items operationalizing the six domains of the minimal generic set were identified. The Partial Credit Model (PCM) was applied to create a health metric based on these items. The Item Response Theory (IRT) model assumptions of unidimensionality, local independence, and monotonicity were evaluated, and Differential Item Functioning (DIF) was examined for sex and age groups. The psychometric properties of: 1)
painDETECT (PD-Q) is a self-reported assessment of pain qualities developed as a screening tool for pain of neuropathic origin. Rasch analysis is a strategy for examining the measurement characteristics of a scale using a form of item response theory. We conducted a Rasch analysis to consider if the scoring and measurement properties of PD-Q would support its use as an outcome measure. Rasch analysis was conducted on PD-Q scores drawn from a cross-sectional study of the burden and costs of NeP. The analysis followed an iterative process based on recommendations in the literature, including examination of sequential scoring categories, unidimensionality, reliability and differential item function. Data from 624 persons with a diagnosis of painful diabetic polyneuropathy, small fibre neuropathy, and neuropathic pain associated with chronic low back pain, spinal cord injury, HIV-related pain, or chronic post-surgical pain was used for this analysis. PD-Q demonstrated fit to the Rasch model after

This study examined the psychometric properties of the eight-item Physical Activity Enjoyment Scale (PACES) in Hong Kong older adults. Study 1 assessed the scales factor validity and test-retest reliability, whereas Study 2 examined its convergent validity in Hong Kong older adults. A total of 168 (Study 1) older adults completed the PACES twice over a 2-week interval, and 57 (Study 2) older adults completed both the eight-item PACES and a measure of quality of life. The results of both studies showed that the eight-item PACES had a high degree of internal consistency. Both the composite reliability and average variance extracted from Study 1 were high, suggesting that as a set, the eight items of the PACES reliably measured the construct. The observed test-retest reliability was satisfactory over a 2-week interval. This eight-item PACES is an expedited and reliable instrument for assessing physical activity enjoyment in Chinese older adults. ...
Results: Findings from the exploratory factor analysis of the MLHFQ revealed three factors (physical, emotional and social) that explained 72 % of the total variance. Mokken analysis confirmed the MLHFQ total scale, and the three subscales, as valid ordinal scales: the total MLHFQ scale [overall Loevinger coefficient (H) = 0.61], physical scale (H = 0.75), emotional scale (H = 0.79) and social scale (H = 0.552). Rasch analysis confirmed the physical scale as a unidimensional scale, but this was not consistent for the total MLHFQ scale which showed poor fit to the Rasch model (χ 2 = 162), df = 42, p , 0.0001). Six items of the total scale were misfitting (7, 8, 10, 14-16) and removing them improved the fit of the total scale. The physical subscale showed fit to the Rasch model (χ 2 = 20.24, df = 16, p = 0.21), and there was evidence of unidimensionality (t tests = 0.09, lower bound 95 % CI 0.04). There was evidence of disordered thresholds for the MLHFQ total and physical scale, and targeting ...
This thesis compromise four studies, three regarding psychometrics and norms of parent rating scales, and one study regarding effectiveness of two different interventions. A normative sample consisting of 1443 parents with children aged 10 to 13 years old, was used in the Study I, II and III. In Study IV, 231 self-referred parents with children aged 10-13 years old with externalizing behavior problem (EBP) were randomized to either Family Check-Up (FCU) or iComet.. The Strengths and Difficulties Questionnaire (SDQ) used in Study I proved to be a reliable and valid instrument with high internal consistency, clear factor structure and high correlation with other similar instruments. In addition, the results support the online use of SDQ as well as using norms obtained through traditional administration even when the SDQ has been administrated online. The Emotion Regulation Questionnaire (ERQ) investigated in Study II was shown to have adequate reliability and construct validity. The specific use ...
Organisations should embrace the use of psychometric assessment to improve their health and safety cultures, according to practitioners in the field.
Comparisons of competing models using confirmatory factor analyses indicated that the four-factor model (somatic symptoms, depressed affect, positive affect, and interpersonal difficulties) possessed the best model fit (CFI=0.98; TLI= 0.98; RMSEA=0.05). CTT analyses showed that the CES-D had satisfactory internal consistency (α=0.74-0.87). Rasch analyses supported the unidimensionality of each CES-D subscale with no misfit item. Rating scale analyses indicated the need to collapse response categories 2 and 3 of the somatic symptoms subscale. Reliability analyses indicated satisfactory item reliability but poor person separation of all subscales. A floor effect for persons and an uneven spread of items across the spectrum were observed. A total of 3 differential item functioning (DIF) items (depressed affect: 1; somatic symptoms: 2) across gender, and 1 DIF item (depressed affect: 1) across the time course of recovery were found but none of them reached practical relevance. All items of the ...

A brief measure is needed to examine the role of hopelessness on mental and physical health outcomes in large population studies. We examined the validity and reliability of two brief measures of hopelessness in a large non-clinical sample, one negatively valenced (Brief-H-Neg) and one positively valenced (Brief-H-Pos). Both were shown to correlate strongly with the longer BHS and mirror the positive correlation seen between the BHS and a measure of depression, providing evidence of concurrent validity, with adequate internal consistency and test-retest reliability.. The sizes of the 2-week retest correlations for the brief measures reported in our non-clinical sample (0.67 and 0.72) are similar to those reported for the BHS in a sample of university undergraduates over a 3-week retest interval (0.67, female students) or a 10-week interval (0.75).25 ,26 Studies assessing the retest reliability of hopelessness instruments have reported varying retest intervals. Hopelessness may be conceptualised ...
Background and Objectives: The aim of the present research is to study the questions used in the 2018 MIR exam (a test that allows access to specialized medical training in Spain), describe their psychometric properties, and evaluate their quality. Materials and Methods: This analysis is performed with the help of classical test theory (CTT) and item response theory (IRT). The answers given to the test questions by a total of 3868 physicians are analyzed. Results: According to CTT, the average difficulty index for all of the test questions was 0.629, which falls into the acceptable category. The average difficulty index with correction for random effects was 0.515, which corresponds to a value within the optimal range. The mean discrimination index was 0.277, which is in the good category, while the mean point biserial correlation coefficient, with a value of 0.275 fits in the regular category. The values of difficulty and discrimination calculated according to the model of two parameters of the IRT

Background The Chronic Pain Coping Inventory (CPCI) has been widely used to measure coping with pain, however, the psychometric properties of the Brazilian CPCI are unknown. Aim To verify the validity and reliability of the CPCI-Brazilian version. Materials and methods A sample of 705 outpatients with chronic pain participated in the study. Cronbachs alpha, corrected item-total correlations, and confirmatory factor analysis were performed, using the method of Diagonally Weighted Least Squares. Results Construct validity was supported with a factor loading range of 0.36-0.90 (9 factors) corroborating original loads. The final model had adequate fit with items 42 and 54 excluded, D.F = 2174, TLI = 0.96; CFI = 0.96 and RMSEA = 0.051(p = 0.067). Eight of the nine CPCI scales showed satisfactory reliability (Cronbachs alpha ranged from 0.70 to 0.92). The Relaxation scale obtained a low alpha value (0.53). Conclusion The CPCI-Brazilian version, after exclusion of items 42 and 54, is valid to measure ...

If you have a question about this talk, please contact Professor John Rust.. Optimal design allows for estimating parameters of statistical models according to important optimality criteria, e. g., minimizing standard errors of estimators. Thus, optimal designs may considerably reduce the number of experimental units, such as respondents or items in empirical studies. For a long time, optimal design has not received much attention within psychology, but meanwhile interest for this subject is rapidly increasing as such designs are needed, e. g., in large scale assessment, adaptive testing or automatic item generation. In this presentation, first, fundamental principles of optimal design are introduced using well-known linear models, e. g. analysis of variance or simple regression. The rationale of adaptive, Bayesian, and minimax designs needed for nonlinear models will then be outlined. Such designs are presented for Item Response Theory (IRT) models, e.g., 1Pl and 2PL model or linear logistic ...

Objective: To test the reliability and the discriminant and convergent validity of the abbreviated Brazilian Portuguese World Health Organizations Quality of Life Instrument - Spirituality, Religion, and Personal Beliefs module (WHOQOL-SRPB BREF). Methods: In a sample of 404 individuals, we applied a general questionnaire, the WHOQOL-BREF, the long-form SRPB, the Brief Religious-Spiritual Coping Scale (RCOPE), and the Beck Depression Inventory (BDI). Priority was given to the 9-item SRPB assessment: its unidimensionality was tested through confirmatory factor analysis and Rasch analysis. Results: Confirmatory factor analysis of the 9-item SRPB assessment indicated an adjusted model with acceptable fit to data. In the Rasch analysis, general fit measures showed adequate performance. The 9-item SRPB assessment showed good internal consistency (alpha = 0.85), and could differentiate (discriminant validity) between religious and atheist/agnostic respondents (mean = 74.7614.1 and 56.8615.5, ...
Academic Motivation Scale: adaptation and psychometric analyses for high school and college students Juliana Beatriz Stover,1 Guadalupe de la Iglesia,1 Antonio Ria,l Boubeta,2 Mercedes Fernández Liporace11Buenos Aires University and National Research Council (CONICET), Buenos Aires, Argentina; 2Santiago de Compostela University, Santiago de Compostela, SpainAbstract: The Academic Motivation Scale (AMS), supported in Self-Determination Theory, has been applied in recent decades as well in high school as in college education. Although several versions in Spanish are available, the underlying linguistic and cultural differences raise important issues when they are applied to Latin-American population. Consequently an adapted version of the AMS was developed, and its construct validity was analyzed in Argentine students. Results obtained on a sample that included 723 students from Buenos Aires (393 high school and 330 college students) verified adequate psychometric properties in this new version, solving
Purpose: The sense of coherence (SOC) scale is widely used and has an extensive history in research. The psychometric properties of the SOC scale have been investigated using classic test theory, but modern test theory enables a more multifaceted investigation of the properties of the SOC scale. The aim of this study was to explore the measurement properties of the SOC scale using the Rasch measurement model.. Methods: SOC questionnaires from a sample of 623 healthy adults were analysed using Rasch analysis. Aspects analysed were rating scale functioning, item fit, unidimensionality, differential item functioning (DIF), targeting, and reliability.. Results: Rating scale analysis showed that the seven scale steps were not utilized in the intended manner and that a shortening to five categories would be beneficial. Twelve out of the 13 items showed acceptable goodness-of-fit and 43 % of the variance was explained by the SOC dimension in the principal components analysis. There was no DIF between ...

onstruct validity with enjoyment and BMI, and on cross-sectional concurrent validity with objectively measured MVPA (tri-axial accelerometry) over the span of seven consecutive days. Study 3 (n = 58) examined the PAQ-C-It reliability, construct validity with BMI and VO₂ max as the objective measurement among a population of children with congenital heart defects (CHD). In study 2 and 3, the factor structure of the PAQ-C-It was then re-examined with an EFA. The PAQ-C-It showed acceptable to good reliability (alpha .70 to .83). Results on construct validity showed moderate but significant association with enjoyment perception (r = .30 and .36), with BMI (r = -.30 and -.79 for CHD simple form), and with the VO₂ max (r = .55 for CHD simple form). Significant concurrent validity with the objectively measured MVPA was reported (rho = .30, p , .05). Findings of the EFA suggested a two-factor structure for the PAQ-C-It, with items 2, 3, and 4 contributing little to the total score. This study ...

OBJECTIVE: The objective was to create a linguistically and culturally validated Swedish version of the Valued Life Activities scale. The aim was also to describe its content and concurrent validity and its internal consistency in persons with rheumatoid arthritis.. METHODS: The Valued Life Activities scale was translated to Swedish and culturally adapted. In order to describe the content validity, both the Swedish and original Valued Life Activities scale were linked to the International Classification of Functioning, Disability and Health. The concurrent validity and internal consistency were evaluated in 737 patients with rheumatoid arthritis. To establish concurrent validity, the scale was correlated to disease activity, activity limitations, and life satisfaction. Internal consistency was assessed with Cronbachs alpha.. RESULTS: The equivalence of meaning between the Swedish and the original Valued Life Activities scale was ensured by harmonization review. Content validity was high when ...
Within structural equation modeling, the most prevalent model to investigate measurement bias is the multigroup model. Equal factor loadings and intercepts across groups in a multigroup model represent strong factorial invariance (absence of measurement bias) across groups. Although this approach is possible in principle, it is hardly practical when the number of groups is large or when the group size is relatively small. Jak, Oort and Dolan (2013) showed how strong factorial invariance across large numbers of groups can be tested in a multilevel structural equation modeling framework, by treating group as a random instead of a fixed variable. In the present study, this model is extended for use with three-level data. The proposed method is illustrated with an investigation of strong factorial invariance across 156 school classes and 50 schools in a Dutch dyscalculia test, using three-level structural equation modeling.
This study evaluated the acceptability and psychometric properties (convergent validity, test-retest reliability and inter-rater reliability) of the Italian version of the Mental Health Recovery Star (MHRS).Convergent validity was assessed by examining readings on MHRS scales and the relevant scales of other validated tools: the Health of the Nation Outcome Scales (HoNOS), World Health Organisation Quality of Life-BREF (WHOQoL-B) and Global Assessment of Functioning (GAF). Temporal stability was tested by 117 service users completing the MHRS two months apart. Finally, inter-rater reliability was examined by 42 keyworkers giving readings for a clinical case, which was described and discussed at the end of a training session.. Service users and keyworkers perceived the Recovery Star as acceptable and easy to use. Convergent validity was demonstrated and there was good test-retest reliability for all areas of the Star. Cohens kappa coefficient was calculated as a measure of inter-rater ...
Background Health-related quality of life (HRQoL) is widely used as an outcome measure in the evaluation of treatment interventions in patients with chronic obstructive pulmonary disease (COPD). In order to address challenges associated with existing fixed-length measures (e.g., too long to be used routinely, too short to ensure both content validity and reliability), a COPD-specific item bank (COPD-SIB) was developed. Methods Items were selected based on literature review and interviews with Dutch COPD patients, with a strong focus on both content validity and item comprehension. The psychometric quality of the item bank was evaluated using Mokken Scale Analysis and parametric Item Response Theory, using data of 666 COPD patients. Results The final item bank contains 46 items that form a strong scale, tapping into eight important themes that were identified based on literature review and patient interviews: Coping with disease/symptoms, adaptability; Autonomy; Anxiety about the course/end-state ...

The Patient Activation Measure (PAM) consists of 13 items and assesses patient (or consumer) self-reported knowledge, skills, and confidence for self-management of ones health or chronic condition. The aim of this study was to translate the original American version of the PAM13 into German and to test the psychometric properties of the German version in an elderly, multimorbid population with various chronic conditions. Translation was performed by a standardized forward-backward translation process. The PAM13 was sent to 9.075 participants enrolled in a randomized controlled study. 4.306 participants responded to the questionnaire. Descriptive and reliability analyses were carried out. To examine scale properties, Andrichs Rasch Rating Scale Model was fitted. The internal consistency is good (α = 0.88) and the item-rest-correlations were found as strong to moderate. The unidimensionality of the construct was confirmed, with a variance explanation of 40.9% and good model-fits for the Rasch model.

In Stage 1, 7 semi-structured focus group discussions (N=56) were conducted to elicit the underlying beliefs specific to tooth brushing. Using content thematic analysis the beliefs were identified and a TPB measure was developed. A repeated measures design was ...
This study was comprised of two phases. In Phase One an intense literature review was performed to facilitate item generation for the initial item-pool. This was then subjected to a review by a panel of experts to establish content validity. Phase Two involved the actual testing of the content validated item pool amongst a sample of ICU nurses from the target population. Ethical approval was obtained from the relevant hospitals. Classical Test Theory was implemented for psychometric evaluation of the instrument. Reliability of the instrument was addressed through the technique of test-retest reliability using Pearsons product-moment correlation coefficient and the Intra-Class correlation coefficient. Finally, the internal consistency of the instrument was addressed to examine the tools stability ...
Evaluating the psychometric properties of a newly developed instrument is critical to understanding how well an instrument measures what it intends to measure, and ensuring proposed use and interpretation of questionnaire scores are valid. The current study uses Structural Equation Modeling (SEM) techniques to examine the factorial structure and invariance properties of a newly developed construct called Superwoman Schema (SWS). The SWS instrument describes the characteristics of a superwoman (strong woman) which consists of 35 items representing five subscales: obligation to present an image of strength, obligation to suppress emotions, resistance to being vulnerable, intense motivation to succeed, and obligation to help others. Multigroup confirmatory factor analysis (CFA) and a multiple indicators multiple causes (MIMIC) model were the SEM approaches used to examine measurement invariance in the SWS instrument. Specifically in the multigroup CFA analyses, configural invariance,

To the best of our knowledge, this study is the first to validate a questionnaire (translated into Brazilian Portuguese) that measures the quality of life of women diagnosed with cervical intraepithelial neoplasia. The FACIT-CD questionnaire was developed by Rao et al. [6] in 2010. To date, no other studies have evaluated the psychometric properties of this instrument, which means that some comparisons are only exploratory.. The first test assessed the reliability of the questionnaire by analysing the internal consistency using Cronbachs alpha coefficient. Results higher than 0.70 indicate that the items on the scales or domains are homogeneous or that they measure the same attribute. In this study, the value on the relationship scale was lower than expected (0.66). However, other authors support the hypothesis that Cronbachs alpha values ​​higher than 0.60 could be acceptable [31]. Despite this assumption, we believe that a value of 0.70 ​​would be more desirable, and thus, we ...
The aim of this study is to develop a self-efficacy measuring tool that can predict the computational thinking skill that is seen as one of the 21st centurys skills. According to literature review, an item pool was established and expert opinion was consulted for the created item pool. The study group of this study consists of 319 students educated at the level of secondary school. As a result of the exploratory factor analysis, the scale consisted of 18 items under four factors. The factors are Reasoning, Abstraction, Decomposition and Generalization. As a result of applied reliability analysis, the Cronbach Alpha reliability coefficient can be seen to be calculated as .884 for the whole self-efficacy scale consisting of 18 items. Confirmative factor analysis results and fit indexes were checked, and fit indexes of the scale were seen to have good and acceptable fits. Based on these findings, the Computational Thinking Self-efficacy Scale is a valid and reliable tool that may be used in ...

A total of 259 Mexican-American, bilingual women (English and Spanish), were recruited for the initial psychometric testing phase of the MBAQ and SMBAQ. The psychometric testing of the MBAQ and SMBAQ included the following steps: a) an estimate of the internal consistency reliability, utilizing Cronbachs alpha reliability coefficient, b) factor analysis, using principal components analysis with Varimax rotation, and c) paired t-test comparison of the means of the MBAQ and SMBAQ to establish their equivalence.. The sample size of 259 women was determined according to the formula of calculating 10 participants per item on a questionnaire (Nunnally & Bernstein, 1994). Since there were 25 items on both the MBAQ and SMBAQ, 250 participants were recruited into the study plus an additional nine participants to allow for questionnaires that would need to be eliminated because of incomplete or missing data on questionnaire items. Inclusion criteria for participants in the initial psychometric testing of ...

About item fit statistics, the models that provided the best fit were the bifactor model, the generalized graded unfolding model and the graded response model, ...
Jose Mestre, Carolyn Anderson, Hua Hua Chang, Gary Gladding and Katherine Ryan are leading a multidisciplinary effort that combines psychometrics and assessment, methodology, and science education to help retention of students in science and engineering. Findings from previous research show that lower performing students do not accurately predict their scores on exams. Such students tend to overestimate their performance, whether they predict performance before or after the exam. This unjustified optimism seems to reflect a tendency to confuse familiarity with the material and competence with the material. This is a critical problem because poor performance in introductory physics leads to poor retention of students in the engineering and science fields. Prof. Mestre and colleagues are tackling this problem from multiple perspectives. First, they are using advances in computer adaptive testing (CAT) to diagnose students problem solving and conceptual deficits prior to taking high-stakes course ...
Attitudes is a key help-seeking construct that influences treatment seeking behavior via intention to seek help, per the theory of planned behavior (TPB). This article presents the development and psychometric evaluation of the Mental Help Seeking Attitudes Scale (MHSAS), designed to measure respondents overall evaluation (unfavorable vs. favorable) of their seeking help from a mental health professional. In Study 1 (N = 857 United States adults), exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and item response theory (IRT) analysis were used to identify an optimal set of 9 items that demonstrated initial evidence of internal consistency, unidimensionality, and strong measurement equivalence/invariance (ME/I) across gender, past help-seeking experience, and psychological distress ...
Premarital sexual behaviors are important issue for womens health. The present study was designed to develop and examine the psychometric properties of a scale in order to identify young women who are at greater risk of premarital sexual behavior. This was an exploratory mixed method investigation. Indeed, the study was conducted in two phases. In the first phase, qualitative methods (focus group discussion and individual interview) were applied to generate items and develop the questionnaire. In the second phase, psychometric properties (validity and reliability) of the questionnaire were assessed. In the first phase an item pool containing 53 statements related to premarital sexual behavior was generated. In the second phase item reduction was applied and the final version of the questionnaire containing 26 items was developed. The psychometric properties of this final version were assessed and the results showed that the instrument has a good structure, and reliability. The results from exploratory
Patients with PAH are confronted with a growing number of therapeutic options, each of which is associated with its own unique delivery system. Because little to no comparative effectiveness data exists, patient preferences can often be the driving factor behind choice of therapy. Thus, treatment satisfaction is likely to be highly relevant in the management of PAH. In this study, we evaluated the psychometric characteristics of a relatively new treatment satisfaction measure, the TSQM, assessed among patients participating in a 12 week open-label study of inhaled PAH therapy. We found that transitioning from inhaled iloprost to inhaled treprostinil was associated with significant improvements in treatment satisfaction as measured by the TSQM. Domains of treatment satisfaction impacted included global satisfaction, effectiveness, and convenience, but not side effects. Overall, the TSQM showed high internal consistency, good convergent validity, and evidence of responsiveness to change over 12 ...
Conventional factor models assume that factor loadings are fixed over a long horizon of time, which appears overly restrictive and unrealistic in applications. In this paper, we introduce a time-varying factor model where factor loadings are allowed to change smoothly over time. We propose a local version of the principal component method to estimate the latent factors and time-varying factor loadings simultaneously. We establish the limiting distributions of the estimated factors and factor loadings in the standard large N and large T framework. We also propose a BIC-type information criterion to determine the number of factors, which can be used in models with either time-varying or time-invariant factor models. Based on the comparison between the estimates of the common components under the null hypothesis of no structural changes and those under the alternative, we propose a consistent test for structural changes in factor loadings. We establish the null distribution, the asymptotic local power
OBJECTIVE: Cancer-related fatigue (CRF) is one of the most common unrelieved symptoms experienced by patients. CRF is underrecognized and undertreated due to a lack of clinically sensitive instruments that integrate easily into clinics. Modern computerized adaptive testing (CAT) can overcome these obstacles by enabling precise assessment of fatigue without requiring the administration of a large number of questions. A working item bank is essential for development of a CAT platform. The present report describes the building of an operational item bank for use in clinical settings with the ultimate goal of improving CRF identification and treatment. STUDY DESIGN AND SETTING: The sample included 301 cancer patients. Psychometric properties of items were examined by using Rasch analysis, an Item Response Theory (IRT) model. RESULTS AND CONCLUSION: The final bank includes 72 items. These 72 unidimensional items explained 57.5% of the variance, based on factor analysis results. Excellent internal ...
OBJECTIVE: To refine and validate the Parental Illness Impact Scale (PIIS), a questionnaire designed specifically to measure the quality of life of adolescent and adult children of neurologically affected parents. METHODS: Key informant interviews and a literature review were conducted to ensure all relevant themes were incorporated in the revised PIIS (PIIS-R). Pre-testing was achieved through a 17 member expert panel and cognitive interviews with eight adolescent and adult children. The revised instrument was administered to 169 adolescent and adult children of people with Parkinsons disease, multiple sclerosis and stroke and subjected to psychometric analysis. RESULTS: Principal components analysis resulted in eight subscales accounting for 60.6% of explained variance. The PIIS-R showed good concurrent and discriminant validity through correlations with established measures of quality of life and psychosocial well-being. Internal consistency was high (Cronbachs alpha .92), and test-retest
There is growing evidence that Internet-mediated psychological tests can have satisfactory psychometric properties and can measure the same constructs as traditional versions. However, equivalence cannot be taken for granted. The prospective memory questionnaire (PMQ; Hannon, Adams, Harrington, Fries-Dias, & Gibson, 1995) was used in an on-line study exploring links between drug use and memory (Rodgers et al., 2003). The PMQ has four factor-analytically derived subscales. In a large (N = 763) sample tested via the Internet, only two factors could be recovered; the other two subscales were essentially meaningless. This demonstration of nonequivalence underlines the importance of on-line test validation. Without examination of its psychometric properties, one cannot be sure that a test administered via the Internet actually measures the intended construct. ...
These findings indicate that this questionnaire has satisfactory reliability and validity. It can detect different levels of satisfaction12 and is therefore suitable for evaluating out of hours care received by a broad range of patients. The questionnaire has satisfactory internal reliability with Cronbachs α coefficients greater than 0.60 for all scales and greater than 0.70 for five.38 The test and retest scores were highly correlated, though the regressions show that the retest scores were generally lower, so that there may have been a real fall in satisfaction with time. In a true test of test-retest reliability the variable and measurement technique should be the same on both occasions. The lower retest scores may therefore also reflect the difference in the method of application, with greater expressed satisfaction when the research assistants were present. Nevertheless, these data indicate that the retest reliability of the questionnaire is broadly satisfactory.. Content validity was ...
TY - JOUR. T1 - Ignoring clustering in confirmatory factor analysis: Some consequences for model fit and standardized parameter estimates. AU - Pornprasertmanit, S. AU - Lee, Jae Hoon. AU - Preacher, K J. PY - 2014. Y1 - 2014. N2 - In many situations, researchers collect multilevel (clustered or nested) data yet analyze the data either Ignoring the clustering (disaggregation) or averaging the micro-level units within each cluster and analyzing the aggregated data at the macro level (aggregation). In this study we investigate the effects of Ignoring the nested nature of data in confirmatory factor analysis (CFA). The bias incurred by Ignoring clustering is examined in terms of model fit and standardized parameter estimates, which are usually of interest to researchers who use CFA. We find that the disaggregation approach increases model misfit, especially when the intraclass correlation (ICC) is high, whereas the aggregation approach results in accurate detection of model misfit in the macro ...
The Beck Anxiety Inventory (BAI) is available in German. Apart from data in its manual, there are no further reports on the psychometric properties of this questionnaire and on its suitability for clinical use in Germany. This study therefore offers an independent investigation into the psychometrics as well as the clinical characteristics of the BAI. Three samples with n=145, n=90, and n=174 comprised inpatients diagnosed with anxiety disorders and treated in a large psychosomatic hospital. In addition to the BAI, the clinician rating Hamilton Anxiety Scale (HamA), the State-Trait-Anxiety Inventory (STAI) as well as the two anxiety subscales of the Symptom Checklist 90 (SCL 90) were used to establish convergent validity ...
Objectives. Measures of acquired immunodeficiency syndrome (AIDS)-related knowledge that have good psychometric properties are needed to evaluate the impact of educational interventions, particularly among impoverished populations. Few measures that satisfy these requirements are available. The authors describe the psychometric characteristics and composition of a subset of 21 AIDS knowledge items from the questionnaire used by the National Center for Health Statistics. Methods. The study was conducted with a convenience sample of women and their significant others or close friends in nine homeless shelters and 11 residential drug recovery programs in the skid row area of Los Angeles from 1991 to 1993. Trained nurses and outreach workers collected data from 486 predominately African-American adults before delivery of well-established, culturally sensitive AIDS educational intervention. A subset of 334 participants were re-interviewed 6 months later. Results. A total scale score was calculated ...
en] The purpose of this talk is to briefly present the logistic regression procedure to identify differential itm functioning (DIF) in psychometrics, and to illustrate the method on a practical data set about intellectual disability. DIF is an important research fi eld and many statistical methods have been developed in this framework. Logistic regression has the asset of not being based on item response models, and it can detect both uniform and nonuniform DIF. In addition, it can be applied to the comparison of more than two groups. This method is illustrated by comparing two groups of French pupils, one group of normal ability students and one group with intellectually disabled students. Ravens Colored Progressive Matrices test is assigned and DIF is investigated between the two groups. It is concluded that none of the items can be flagged as functioning differently ...
Study I describes the development of the Hand Assessment for Infants (HAI). The HAI is an assessment tool that constitutes of 17 observable items all measuring different aspects of goal oriented hand use. Twelve of the items are unimanual, scored for the right and the left hand separately, and five items are bimanual where one score is given. All items are scored on a three-point rating scale (0-2) and the scores of the unimanual items are summed to the Each Hand Sum score (EaHS) with a range of 0-24 raw scores. The EaHS of the better functioning hand and the lesser functioning hand is used to calculate an asymmetry index where a higher percentage indicates a larger asymmetry. The results of all the items are added to the Both Hands Sum score (0-58 raw scores) that has been converted to logits through the Rasch measurement model analysis to become the Both Hands Measure (BoHM), an interval scale of 0-100 HAI-units and the main outcome of the HAI ...

Background: Existing measurement instruments for depression are most often based on symptoms observed in western clinical populations. It remains unclear whether these instruments are appropriate for use in epidemiologic, screening, intervention monitoring and evaluation, and clinical settings in non-western contexts. The overall goal of this study was to determine if there is a need for new instruments with global applicability to measure depression, and if so, to develop and test this new instrument. Methods: Two approaches were used in this process: 1) a systematic literature review of qualitative studies to identify common symptoms related to depression across populations; and 2) a quantitative analysis of existing datasets using item response theory (IRT) to identify how different symptom questions related to depression perform across settings. Results from these investigations were used to inform the development of the International Depression Symptom Scale (IDSS), an instrument designed ...
Background: FertiQoL, which measures the Quality of Life (QOL) of reproductive partners, has been translated and used in 45 languages in the world. The reliability and validity of the original English version of FertiQoL have been confirmed. However, there is still _disibledevent= 0.059. The correlation coefficient was 0.669 (p < 0.001) with the distress scale. Conclusions: The Japanese version of FertiQoL showed adequate reliability and validity for assessing the QOL of patients with reproductive problems in Japan.
