In assessing criminality, researchers have used counts of crimes, arrests, and so on, because interval measures were not available. Additionally, crime seriousness varies depending on demographic factors. This study examined the Crime and Violence Scale (CVS) regarding psychometric quality using item response theory (IRT) and invariance of the…

The second edition of this essential handbook provides a comprehensive, updated overview of the science that informs best practices for the implementation of response to intervention (RTI) processes within Multi-Tiered Systems of Support (MTSS) to facilitate the academic success of all students. The volume includes insights from leading scholars…

Despite the increasing interest in and need for test information for use in instructional practice and student learning, there have been few attempts to systematically link a diagnostic approach to English for academic purposes (EAP) writing instruction and assessment. In response to this need for research, this study examined the extent to which…

The climate of school classrooms, shaped by a combination of teacher practices and peer processes, is an important determinant for children's psychosocial functioning and is a primary factor affecting bullying and victimization. Given that there are relatively few theoretically grounded and validated assessment tools designed to measure the social…

The impact of the environment on the quality of life and health is considered to be important for adults as well as for children and adolescents. To include the subjective view of children and adolescents in this context, instruments for measuring the perception of the environment are needed. The new scale CANEP (Children's and Adolescents'…

This paper analyzes the sum score based (SSB) formulation of the Rasch model, where items and sum scores of persons are considered as factors in a logit model. After reviewing the evolution leading to the equality between their maximum likelihood estimates, the SSB model is then discussed from the point of view of pseudo-likelihood and of…

The Penn State Worry Questionnaire for Children (PSWQ-C; Chorpita, Tracey, Brown, Collica, & Barlow, 1997) is a 14-item self-report measure of worry in children and adolescents. Although the PSWQ-C has demonstrated favorable psychometric properties in small clinical and large community samples, this study represents the first psychometric…
