Quality of life is widely acknowledged as one of the most important outcomes in autism research, but few measures of this construct have been validated for use in autistic people. The goal of the current study was to examine the psychometric properties of the Patient-Reported Outcomes Measurement Information System Global--10, an established…

This study involved a systematic and evaluative review of school climate measures to catalog main domains and subdomains and rate parameters of instrument presentation and psychometric quality. Four databases were used (Web of Science, Scopus, ERIC, and PsycINFO) and 37 instruments (studies) met inclusion criteria (instrument measured school…

Early identification of language delay is important as it has a serious impact on a child's life in terms of educational, social, and emotional development. Among the early language screening tools, there are some parent-administered tools; however, they are not culturally appropriate or freely available. This article documents the development and…

Identifying student strengths is central to transition planning. However, school personnel use few assessments that operationalize behavioral and emotional strengths, and the psychometric functioning of those measures have not been established with transition-age students. In this two-part study, we used a national sample of transition-age…

The goal of this study was to extend research on scale contextualization (i.e., frame-of-reference effect) to the decision making styles construct, compare the effects of contextualization across three unique decision style scales, and examine the consequences of scale contextualization within an item response theory framework. Based on a mixed…

This study examined psychometric properties of scores on the Depression Anxiety Stress Scales-21 (DASS-21) with a nonclinical sample of senior games athletes (N = 383). Information on the internal reliability, item-scale correlations, structural validity, and concurrent validity of the DASS-21 scores is provided to test its applicability to senior…

Background: Dynamic, relational developmental systems-based models of development emphasize that developmentally-nurturant youth-adult relationships elicit in youth perceptions of being known and loved. Although such perceptions are foundations of positive youth development (PYD), such measures do not exist. Objective: We sought to create a…

Within educational and social discourses, the term 'inclusion' has various meanings. In both research and practice, there is no official definition of inclusion. Nevertheless, subjective definitions affect pedagogical acts. We developed the Definitions of Inclusion Questionnaire ["Fragebogen zur Erfassung subjektiver Definitionen von…

Studies have shown that the School Kindness Scale (SKS) has adequate psychometric properties in different societies such as Canada, Turkey, and the Philippines. However, there is scarce evidence on the psychometric validity of this scale across multiple societies and educational contexts. This study explores the cross-national invariance of the…

Computational thinking (CT) is an emerging and multifaceted competence important to the computing era. However, despite the growing consensus that CT is a competence domain, its theoretical and empirical account remain scarce in the current literature. To address this issue, rigorous psychometric evaluation procedures were adopted to investigate…

Background: Implementation of Health Promoting School (HPS) programs can be challenging due to the dynamic school context. Navigating between program fidelity and adaptation, as well as integrating the program, is essential for successful implementation, and consequently, for program effects. As part of an evaluation study in the Netherlands, this…

In order to support research on school effectiveness, there is a need for valid and reliable instruments to assess policymaking capacities of schools. Increasingly, policymaking is seen as a shared responsibility of the entire pedagogical team of a school. In this article, data were analysed from a sample of 1,696 (care) teachers coordinators and…

Computational thinking (CT) has permeated primary and early childhood education in recent years. Despite the extensive effort in CT learning initiatives, few age-appropriate assessment tools targeting young children have been developed. In this study, we proposed Computational Thinking Test for Lower Primary (CTtLP), which was designed for lower…

This paper summarizes the development and validation of the Revised Affirmative to Problem Parenting Scale (R-APPS) using a sample of 643 adults with disabilities. Results of exploratory factor analysis, confirmatory factor analysis, correlations, and reliability estimates reveal sound psychometric structure for a 4-factor scale distinguishing…

The "Child Behavior Checklist for Ages 1.5-5" (CBCL/1½-5) has been widely used by researchers and clinicians in the field of special education and psychology. The purpose of this study was to examine the psychometric properties of the CBCL/1½-5 with a sample of preschool children from low-income families using the Rasch model.…
