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 ...

Rasch analysis of an instrument for measuring occupational value : Implications for theory and practiceRasch analysis of an instrument for measuring occupational value : Implications for theory and practice
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 ...
Psychometrics - WikipediaPsychometrics - Wikipedia
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 ...
Canadian-French, German and UK versions of the Child Health Questionna by J. M. Landgraf, E. Maunsell et al."Canadian-French, German and UK versions of the Child Health Questionna" by J. M. Landgraf, E. Maunsell et al.
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

A Singular View of Psychometric Data. :: PsycCRITIQUESA Singular View of Psychometric Data. :: PsycCRITIQUES
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 ...
Development of a metric for tracking and comparing population health based on the minimal generic set of domains of functioning...Development of a metric for tracking and comparing population health based on the minimal generic set of domains of functioning...
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

Psychometric Properties of Eight-Item Physical Activity Enjoyment Scale in a Chinese Population in: Journal of Aging and...Psychometric Properties of Eight-Item Physical Activity Enjoyment Scale in a Chinese Population in: Journal of Aging and...
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. ...
An evaluation of the Minnesota Living with Heart Failure Questionnaire using Rasch analysis - UQ eSpaceAn evaluation of the Minnesota Living with Heart Failure Questionnaire using Rasch analysis - UQ eSpace
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 ...
The emotion regulation questionnaire : Psychometric properties and norms for Swedish parents of children aged 10-13 yearsThe emotion regulation questionnaire : Psychometric properties and norms for Swedish parents of children aged 10-13 years
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 ...

ACRM 96th Annual MeetingACRM 96th Annual Meeting
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.

Identifying hopelessness in population research: a validation study of two brief measures of hopelessness | BMJ OpenIdentifying hopelessness in population research: a validation study of two brief measures of hopelessness | BMJ Open
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

talks.cam : Optimal Design for Item Response Theory Modelstalks.cam : Optimal Design for Item Response Theory Models
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 ...

Individuals differ in the intensity of exercise they prefer and the intensity they can tolerate. The purpose of this project was to develop a measure of individual differences in the preference for and tolerance of exercise intensity. The steps involved in (a) item generation and face validation, (b) exploratory factor analysis and item selection, (c) structural validation, (d) examination of the internal consistency and test-retest reliability, (e) concurrent validation, and (f) construct validation are described. The Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q) is a 16-item, 2-factor measure that exhibits acceptable psychometric properties and can be used in research aimed at understanding individual differences in responses to exercise and thus the psychological processes involved in the public health problem of exercise dropout. ...

Development of an item bank for computerized adaptive test (CAT) measurement of pain - White Rose Research OnlineDevelopment of an item bank for computerized adaptive test (CAT) measurement of pain - White Rose Research Online
Purpose: Patient-reported outcomes should ideally be adapted to the individual patient while maintaining comparability of scores across patients. This is achievable using computerized adaptive testing (CAT). The aim here was to develop an item bank for CAT measurement of the pain domain as measured by the EORTC QLQ-C30 questionnaire. Methods: The development process consisted of four steps: (1) literature search, (2) formulation of new items and expert evaluations, (3) pretesting and (4) field-testing and psychometric analyses for the final selection of items. Results: In step 1, we identified 337 pain items from the literature. Twenty-nine new items fitting the QLQ-C30 item style were formulated in step 2 that were reduced to 26 items by expert evaluations. Based on interviews with 31 patients from Denmark, France and the UK, the list was further reduced to 21 items in step 3. In phase 4, responses were obtained from 1103 cancer patients from five countries. Psychometric evaluations showed that ...

Students perceived understanding and competency in probability concep by M Zamalia and Anne L. Porter"Students' perceived understanding and competency in probability concep" by M Zamalia and Anne L. Porter
Student understanding and competency in probability have been investigated from different perspectives. Competency is often measured in the form of tests. The purpose of this study was to investigate whether perceived understanding and competency can be calibrated and assessed together using Rasch measurement tools. The study comprised 44 students who enrolled in the STAT131 Understanding Uncertainty and Variation course at University of Wollongong, Australia. Their voluntary participation in the study was through the e-learning Moodle platform where tests and assessment were administered online. Data were analysed using the Rasch measurement models. The study revealed majority of the students had little understanding about conditional and independent events prior to learning them but tended to demonstrate a slightly higher competency level afterward. Based on the Rasch map, there is an indication of some increase in learning and knowledge about probability concepts at the end of the two weeks lesson.

Validation of the functional assessment of cancer therapy cognitive sc by Sheri R. Jacobs"Validation of the functional assessment of cancer therapy cognitive sc" by Sheri R. Jacobs
Research has demonstrated that cancer patients report problems with cognitive functioning related to their cancer and their cancer treatments. Cognitive complaints refer to subjective reports of problems such as decreased memory, attention, concentration, and language skills. These problems with cognitive functioning can interfere with a persons quality of life. The current measures of cognitive complaints have poor or unknown psychometric properties. Therefore, the present study sought to examine the psychometric properties of a newly developed measure of cognitive complaints for cancer patients, the Functional Assessment of Cancer Therapy Cognitive Scale (FACT-Cog). Eighty-two patients were administered a comprehensive battery of neuropsychological tests assessing memory, executive functioning, motor, and attention, as well as a battery of psychosocial measures six months or twelve months after receiving a bone marrow transplant. Results indicated that the internal consistency reliability of the FACT

An item response theory evaluation of three depression assessment instruments in a clinical sample | BMC Medical Research...An item response theory evaluation of three depression assessment instruments in a clinical sample | BMC Medical Research...
Certainly, the main difficulty of this study is the limited sample size. However, the aim was to find a way to reasonably evaluate rating scale type assessment instruments at an early stage (which implies a small sample), and thereby make it possible to introduce improvements or evaluate the appropriateness of their use before a further large scale application. Furthermore, the history tells us that small studies are carried out quite frequently. We therefore suggest this 3- step strategy, which starts out from the use of sum score as the aggregated message from an instrument. It is well known that statistical models are vulnerable when applied on small samples. The sum score model is a model based solely on conditions in the assessment instrument - equally weighted items with unit distances between item categories - a fact which is often overlooked. In step 1, the nonparametric approach, basic characteristics are revealed with as few modelling restrictions as possible and form the basis for ...

Revisiting developmental assessment of children. Schek 17 adapted the general functioning scale of the family to another cultural context, with a sample of 4, Chinese adolescents. The author obtained significant results similar to those investigated here: temporal stability and good internal consistency, good construct and concurrent validity, and the ability to discriminate between clinical and nonclinical groups. The author points out that the significant correlation of the GFF scale with other family functioning measures is a relevant finding, especially since the GFF is a fairly reduced scale compared to the others.. This result is at odds with Morris 13 and Aarons et al. Other studies report GFF scale measurement equivalence data. Georgiadis et al. This may indicate that this item represents the same idea of other items, therefore being redundant in this instrument. In the analysis, items 2 and 9 were maintained, despite the correlation. Operationally, this option would allow for ...

PresentationsPresentations
Dr. Bjorner will describe the unique features of item banks and CAT, discuss how to develop item banks, and describe some of the opportunities and challenges for using CAT in medical research. In CAT, a computer selects the items from an item bank that are most relevant for and informative about the particular respondent; thus optimizing test relevance and precision. Dr. Bjorner will discuss principles and practical experiences in developing item banks and CAT for health outcomes. In addition to the careful psychometric analysis, the clinical application of PROM assessments needs clear construct definitions, good items, and well-founded interpretation guidelines. The application of CAT in medical research offers new opportunities and challenges for test strategies and for the statistical analysis of data from a CAT. The strongest statistical analysis is usually achieved through expanded IRT models that specify the research question of interest as a parameter in the model. Such specialized IRT ...
