A pre-rule for the sequential probability ratio test in a between-item grid multidimensional computerized classification test.

The measurement efficiency of a grid multidimensional computerized classification test (grid MCCT), which makes a classification decision per dimension, can be improved by taking the correlations between the dimensions into account in the termination criterion. The higher the correlations, the better the improvement in measurement efficiency. However, a termination criterion utilizing inter-dimensional information (i.

A New Approach to Desirable Responding: Multidimensional Item Response Model of Overclaiming Data.

A variety of approaches have been presented for assessing desirable responding in self-report measures. Among them, the overclaiming technique asks respondents to rate their familiarity with a large set of real and nonexistent items (foils). The application of signal detection formulas to the endorsement rates of real items and foils yields indices of (a) and (b) .

Error patterns of facial emotion recognition in patients with schizophrenia.

Error patterns of facial emotion recognition (FER) indicate how individuals misinterpret others' facial expressions, which helps clinicians to manage related deficits. However, previous investigations are limited and may have been biased due to methodological issues (e.g.

Improving test efficiency for a grid multidimensional computerized classification test by the application of a conditional latent-trait distribution to a sequential probability ratio test.

The measurement efficiency of a multidimensional computerized adaptive testing (MCAT) can be improved by taking the correlations between the dimensions into account during the item selection and latent-trait estimation procedures (Segall, 1996; Wang & Chen, 2004). Although a multidimensional computerized classification test (MCCT), which was based on a multidimensional itemresponse model, was previously found more efficient than its unidimensional counterpart, the difference was negligible (Seitz & Frey, 2013); the researchers had adopted a sequential probability ratio test (SPRT) as the termination criterion in this MCCT study. To make a classification decision on each dimension, which is called a grid classification (Wang et al.

An Exploratory Strategy to Identify and Define Sources of Differential Item Functioning.

The sources of differential item functioning (DIF) items are usually identified through a qualitative content review by a panel of experts. However, the differential functioning for some DIF items might have been caused by reasons outside of the experts' experiences, leading to the sources for these DIF items possibly being misidentified. Quantitative methods can help to provide useful information, such as the DIF status and the number of sources of the DIF, which in turn help the item review and revision process to be more efficient and precise.

A psychometric analysis of a short form of the Chinese version of the ISPCAN child abuse screening tools - Children's home version (SC-ICAST-CH) using multidimensional item response theory.

Background: The development of measures of child maltreatment for the Chinese population were limited until the Chinese version of the ISPCAN Child Abuse Screening Tools - Children's Home version (ICAST-CH-C) was proposed. Although the ICAST-CH-C was found to be effective in assessing the scope and prevalence of child maltreatment, it has several potential drawbacks. The time that is required to complete the ICAST-CH-C scale is longer than usual for a 36-item scale, because many of its items have one or more follow-up questions.

A prospective study of the responsiveness of the original and the short form Berg Balance Scale in people with stroke.

Objective: The study aim was to examine the responsiveness of the Berg Balance Scale (BBS) and that of its short form (SFBBS) at both the individual person level and the group level.

Design: A repeated-measurements design.

Setting: Hospital and home setting.

Examining unidimensionality and improving reliability for the eight subscales of the SF-36 in opioid-dependent patients using Rasch analysis.

Purpose: The Medical Outcome Study Short Form 36 (SF-36) is one of the most commonly used questionnaires for monitoring the Health-Related Quality of Life (HRQOL) of opioid-dependent patients. However, the unidimensionality and reliability of the SF-36 have not been verified in opioid-dependent patients. The aim of this study was to examine the unidimensionality and to improve the test reliability of the SF-36 for use in opioid-dependent patients.

Validating and improving the reliability of the EORTC qlq-c30 using a multidimensional Rasch model.

Objective: The reliability and validity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) has not been examined while taking into account the correlation between subscales. The reliability of the EORTC QLQ-C30 subscales is modest, thus limiting their utility in both clinical and research settings. The purpose of this study was to validate the factor structure of multiple-item subscales of the EORTC QLQ-C30 and to improve their reliability by means of an item response analysis by using the multidimensional partial credit model.

Development of a computerized adaptive testing system of the Fugl-Meyer motor scale in stroke patients.

Objective: To develop a computerized adaptive testing system of the Fugl-Meyer motor scale (CAT-FM) to efficiently and reliably assess motor function in patients with stroke.

Design: First, a simulation study was used to develop and examine the psychometric properties of the CAT-FM. Second, a field study was employed to determine the administration efficiency of the CAT-FM.

Development and initial validation of the Preschooler Gross Motor Quality Scale.

Motor skills have great impact on children in adapting to an environment and developing interpersonal interaction, cognition, and social behavior. Understanding what children can do and how they perform it is essential. Most motor tests seldom contain quality evaluation in the items or criteria.
