The Classroom Learning Activities Checklist (CLAC) is a brief classroom observation measure that assesses task-oriented and self-regulated learning in early childhood environments. We assessed the tool's dimensionality and validity in predicting prekindergarten (PreK) learning gains. The study sample is from the Midwest Child-Parent Center (MCPC)…

The prevalence of bullying has increased over the past decade and is a public health concern. Existing measures of bullying lack breadth and/or psychometric support, which may inaccurately represent current rates of bullying. The purpose of this study was to develop and validate a psychometrically sound measure, the Multidimensional Bullying…

The Hellenic WISC-III (Wechsler, 1997) is currently the only standardized and officially published tool for the assessment of the intelligence of children and adolescents in Greece. The test is also used with caution in Cyprus, among Greek speakers, but no specific norms exist for use in this country. The purpose of this study was to provide…

In this paper, the Classroom Learning Activities Checklist (CLAC) is proposed as a classroom observation measure that effectively captures the classroom environments and strategies that support self-regulation via task-oriented learning in young students. The CLAC's dimensionality, reliability, and concurrent and predictive validity evidence are…

Personality disorder is prevalent among offenders with intellectual disabilities (ID), and it is associated with their risk for violence and recurrent offending behaviour. A new staff-rated instrument, the Personality Disorder Characteristics Checklist (PDCC), designed to screen for ICD-10 dissocial and emotionally unstable personality…

This article presents information on the development and initial validation of the 16-item Response to Intervention (RTI) Beliefs Scale. The scale is designed to measure the extent to which educators working in schools hold beliefs consistent with the tenets of RTI. The authors administered the instrument to 2,430 educators in 62 elementary…

The Resilience Scale for Adults (RSA) was developed and has been extensively validated in Norwegian samples. The purpose of this study was to explore the construct validity of the Resilience Scale for Adults in a French-speaking Belgian sample and test measurement invariance between the Belgian and a Norwegian sample. A Belgian student sample (N =…

This study aimed to establish the validity of the Language Development Rating Scale and the Attitudes toward Reading and Voluntary Reading Behaviour Rating Scale in Morrow's Checklist for Assessing Early Literacy Development for use with preschool children in Hong Kong.

The Behavior Problems Inventory-Short Form (BPI-S) is…

Background: Different dimensions of oppositional defiant disorder (ODD) have been found as valid predictors of further mental health problems and antisocial behaviors in youth. The present study aimed at testing the construct, concurrent, and predictive validity of ODD dimensions derived from parent- and self-report measures. Method: Confirmatory…

Two self-report measures of psychopathy, Levenson's Primary and Secondary Psychopathy scales (LPSP) and the Psychopathic Personality Inventory (PPI), were administered to a large sample of 1,603 offenders. The most widely researched measure of criminal psychopathy, the Hare Psychopathy Checklist-Revised (PCL-R), served as a provisional referent…

This study used item response theory (IRT) to examine the Impulsive Behaviors Checklist for Adolescents (IBCL-A) among 6,276 (67.7% girls) Chinese secondary school students. The IBCL-A included 15 maladaptive impulsive behaviors adapted from the Revised Diagnostic Interview for Borderlines. The authors obtained the severity and discrimination…

The Psychopathy Checklist-Revised (PCL-R) is the most widely used measure of psychopathy in forensic clinical practice, but the generalizability of the measure to offenders with intellectual disabilities (ID) has not been clearly established. This study examined the structural equivalence and scalar equivalence of the PCL-R in a sample of 185 male…

This study explores the psychometric properties of data drawn from the Korean translation of the full "Scales of Independent Behavior--Revised" (SIB-R). In addition, semantic, content, conceptual, and technical equivalence are examined. The participants include 2,763 typically developing children and 406 children with intellectual…
