Person-fit statistics have been proposed to investigate the fit of an item score pattern to an item response theory (IRT) model. The author investigated how these statistics can be used to detect different types of misfit. Intelligence test data were analyzed using person-fit statistics in the context of the G. Rasch (1960) model and R. J. Mokken's (1971, 1997) IRT models. The effect of the cho...

BACKGROUND No studies have compared the 2-factor structures of Wong's and Post's versions of the short-form Stroke-Specific Quality of Life (i.e., 12-item SSQOL) scale. This study compared the construct validity of 2 short-forms of the 12-item-SSQOL (not the 12-domain-SSQOL). METHODS Data were obtained from a previous validation study of the original 49-item SSQOL in 263 patients. Construct v...

The short Expagg scale is a psychometric measure of social representations of expressive and instrumental aggression developed by Campbell, Muncer, McManus and Woodhouse (1999). Confirmatory factor analysis (CFA) was used to compare the 16-item and 10-item versions of the scales on their goodness of fit to a proposed two-dimensional model. On a sample of 1,000 respondents, the 5-item version sh...

BACKGROUND Self-efficacy is needed for effectuating lifestyle changes, and it is therefore an important target related to health. The purpose of this study was to evaluate the psychometric properties of the General Self-Efficacy Scale (GSE) using Rasch analysis in a sample of adults with morbid obesity. METHODS A convenience sample of adults with morbid obesity was recruited from patient educ...
