BACKGROUND Participation in education is a vital component of adolescents' everyday life and a determinant of health and future opportunities in adult life. The School Setting Interview (SSI) is an instrument which assesses student-environment fit and reflects the potential needs for adjustments to enhance students' participation in school activities. The aim of the study was to investigate the...

Investigating the existence of items with differential item functioning (DIF) may provide more accurate comparisons group differences in studies that aim to compare scores obtained a test by groups different characteristics. In present study, scale measuring critical thinking motivation was adapted Turkish culture applied 817 participants, who were high school graduates, university students, an...

Aim This study tested the construct validity (i.e., factor structure) of Persian Mindful Attention Awareness Scale (MAAS) on a sample male prisoners. Methods All participants (mean±SD age = 39.44±7.94 years) completed three scales—the MAAS, Insomnia Severity Index (ISI), and 12-item General Health Questionnaire (GHQ-12). Confirmatory analysis (CFA) Rasch with differential item functioning (DIF)...

BACKGROUND. Mastery refers to the degree to which people perceive that they can control factors that influence their life situation, and has been found important for people’s quality of life and well-being. It is thus essential to be able to measure mastery in a valid and reliable way. AIM. This study aimed at using the Rasch measurement model for investigating the psychometric properties of a ...

OBJECTIVE To determine the content, structural, and construct validity of the Dutch version of the Neck Disability Index (NDI). STUDY DESIGN AND SETTING To assess content validity, 11 neck pain experts and 10 patients commented on the construct, comprehensiveness, and relevance of the NDI. Structural validity was assessed by item factor analysis (FA) and item response theory modeling using th...

Understanding and accounting for gender performance differences on high stakes examinations has become a particular concern for educational researchers to ensure test fairness for all examinees. In the context of second/foreign language proficiency testing, research (Ryan and Bachman, 1992) suggests that males and females do not react differently at the item level. However, as Nandakumar (1993)...

Measurement invariance is a prerequisite for confident cross-cultural comparisons of personality profiles. Multigroup confirmatory factor analysis was used to detect differential item functioning (DIF) in factor loadings and intercepts for the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) in comparisons of college students in the United States (N = 261), Philippines...

We evaluated the psychometric properties of the Cambridge Face Memory Test (CFMT; Duchaine & Nakayama, 2006). First, we assessed the dimensionality of the test with a bifactor exploratory factor analysis (EFA). This EFA analysis revealed a general factor and 3 specific factors clustered by targets of CFMT. However, the 3 specific factors appeared to be minor factors that can be ignored. Second,...

The psychotree package contains the function raschtree, that can be used to detect differential item functioning (DIF) in the Rasch model. The DIF detection method implemented in raschtree is based on the model-based recursive partitioning framework of Zeileis, Hothorn, and Hornik (2008) and employs generalized M-fluctuation tests (Zeileis and Hornik 2007) for detecting differences in the item ...
