Item response theory was used to study the psychometric properties of the Client Meaningful Experiences Scale (CMES). In a sample of 306 adult counseling clients, we examined the dimensional structure of the scale, item-fit, and person-fit statistics. Implications of these findings for counselors, counselors-in-training, and counseling researchers…

Community-based participatory research (CBPR) is an emerging research approach with the aim of increasing sampling of diverse populations in studies. The purpose of this study was to evaluate the psychometric properties of scores on the CBPR Knowledge Self-Assessment Scale (CBPR-KSAS) using Rasch analysis. The scale was completed by 204…

We assessed the psychometric properties of the visual analog scale (VAS) form of the Outcome Rating Scale (ORS) using item response theory (IRT) with a sample of 2,109 Canadian counseling clients. Findings indicate that the ORS was unidimensional and that the equal-interval assumption was not tenable for the VAS.

The psychometric properties of the 2 versions of the Junior Metacognitive Awareness Inventory were examined with Singapore student samples. Other than 2 misfitting items and an underutilized response scale, Rasch analysis demonstrated that the instruments have good measurement precision, and no differential item functioning was detected across…

Research focused on student belonging has sometimes used available measures in a unidimensional way despite evidence of multidimensionality in these scales. This study introduces a new unidimensional measure of school belonging that is psychometrically robust with preliminary evidence of construct validity that we call the Simple School Belonging…

This study examines the psychometric features of a General Aptitude Test-Verbal Part, which is used with assessments of high school graduates in Saudi Arabia. The data supported a bifactor model, with one general factor and three content domains (Analogy, Sentence Completion, and Reading Comprehension) as latent aspects of verbal aptitude.

The psychometric properties of the General Functioning subscale of the McMaster Family Assessment Device were examined using the Rasch Model (N = 237 couples). Mothers' and fathers' ratings of the General Functioning subscale of the McMaster Family Assessment Device are recommended, provided these are analyzed separately. More than a quarter of…

The purpose of this study was to investigate psychometric properties of the Children's Depression Inventory within a nonclinical and longitudinal sample (8th and 12th grades). Using the Rasch rating scale, most items represented one dimension. There was adequate separation among items and no overlap between ranges of item difficulties with latent…

In this study, psychometric properties of a Korean-adapted version of the Experiences in Close Relationships--Revised scale were investigated using confirmatory factor analysis (CFA) in conjunction with item response theory. In CFA, neither the supposed two-factor model of Anxiety and Avoidance nor two single-factor models for each factor showed a…

The psychometric properties of measures of self-efficacy for the six themes of Holland's theory were examined using item response theory. Item and scale quality were compared across levels of the trait continuum; all the scales were highly reliable but differentiated better at some levels of the continuum than others. Applications for adaptive…

The Math and Me Survey was designed to measure elementary students' attitudes toward mathematics. The authors conducted content validation, exploratory factor analysis, confirmatory factor analysis, item response theory, reliability, and external validity analyses to improve it and to test its psychometric properties. The final Math and Me Survey…

The author used Rasch measurement to examine the reliability and validity of 382 Korean university students' scores on the Marlowe-Crowne Social Desirability Scale (MCSDS; D. P. Crowne and D. Marlowe, 1960). Results revealed that item-fit statistics and principal component analysis with standardized residuals provide evidence of MCSDS'…

Examined the psychometric properties of the Situational Confidence Questionnaire (SCQ) in adolescents (N=662). Results indicate that an eight-factor model fit the data in the same pattern as found in adults. The SCQ's reliability coefficient was high and it comprised highly discriminating items. Modifications, therefore, are unnecessary when…
