This study examined the psychometric properties of the Ego Resiliency Scale-Revised (ER89-R). Though support exists for a multidimensional conceptualisation using classical test theory approaches (i.e., a higher-order model comprising Openness to Life Experiences and Optimal Regulation factors), this measure has not been subjected to Rasch…

The present study sought to examine the psychometric properties of the French and German versions of the Physical Self-Concept Questionnaire for Elementary School Children-Revised (PSCQ-C-R). A sample of 519 children participated in this study. Of those, 197 were French-Canadian and 322 were German. Results support the factor validity and…

Physical self-concept plays a central role in older adults' physical health, mental health and psychological well-being; however, little attention has been paid to the underlying dimensions of physical self-concept in the elderly. The purpose of this study was to develop and validate a new measurement for older adults. First, a qualitative study…

Psychometric and utility studies on Social Emotional Assessment Measure (SEAM), an innovative tool for assessing and monitoring social-emotional and behavioral development in infants and toddlers with disabilities, were conducted. The Infant and Toddler SEAM intervals were the study focus, using mixed methods, including item response theory…

The comparison of scores from linguistically different tests is a twofold matter: the adaptation of tests and the comparison of scores. These 2 aspects of measurement invariance intersect at the need to guarantee the psychometric equivalence between the original and adapted versions. In this study, the authors examined comparability in 2 stages.…

Differential item functioning (DIF) in the Multidimensional Self Concept Scale (B. A. Bracken, 1992) was evaluated using 2 different methods to identify and describe DIF. Of 149 items from the Multidimensional Self Concept Scale, 42% exhibited gender DIF. Nonuniform, crossover DIF was evident in items throughout the instrument.

Reliability and validity of the Offer Self-Image Questionnaire (OSIQ) for adolescents were studied in an Australian sample of 72 male and 144 female high school students. The OSIQ was found to be reliable for appropriate research with adolescents. Further work is needed to improve item content and the present subscales. (SLD)
