This article describes the development of the Multi-Tiered System of Supports-Interventionist Beliefs Scale (MTSS-IBS). The introduction reviews the importance between practitioner beliefs and MTSS success. Because there is no measure to assess the MTSS beliefs of school interventionists for the success of all students, we used a principal…

School-wide positive behavior interventions and supports (SWPBIS) is widely implemented across the United States. Evidence suggests that SWPBIS, when implemented with fidelity, has a significant and positive impact on schools, including lower suspensions and higher reading and mathematics achievement. A critical component of this research is…

The goal of the present study was to investigate the factor structure of the Bullying Participant Behaviors Questionnaire in an independent elementary school sample. The BPBQ is a self-report inventory that purports to measure participation or experiences in five bullying roles: perpetrator, target, assistant, defender, and outsider. The current…

At present, there are no brief, freely-available, informant-report measures that evaluate key challenging behaviors relevant to youth with autism spectrum disorder (ASD) or other developmental disabilities (DD). This paper describes the development, refinement, and initial psychometric evaluation of a new 18-item measure, the Open-Source…

Over the last two decades, cyberbullying has gained increasing attention from the research community as the phenomenon has become a public health issue affecting children, adolescents, and young adults. Although several instruments assess cyberbullying worldwide, many still need to be adequately validated in different languages, countries, and…

This study examined the development and technical adequacy of the Interventionist Knowledge and Skill Survey (IKSS), a self-assessment used for understanding the degree of knowledge and skills associated with interventionists working within a multitiered system of support (MTSS). A national sample of 600 school psychologists and school counselors…

Background: Active learning supports student performance, but can be challenging to implement in large courses. The Learning Assistant (LA) Program is a growing intervention to support students in large active learning classrooms. This program places advanced undergraduates who have training in pedagogical methods in active learning classrooms to…

Purpose: This study examines the psychometric properties of the Teamwork Scale for Youth, an assessment designed to measure youths' perceptions of their teamwork competency. Methods: The Teamwork Scale for Youth was administered to a sample of 460 youths. Confirmatory factor analyses examined the factor structure and measurement invariance of the…

Introduction: This article has two objectives: a) to examine the factorial structure of the Spanish version of the EPQR-A through an exploratory factor analysis and b) to perform a confirmatory factor analysis to determine the psychometric properties of the Spanish version of the EPQR-A in terms of construct validity in an adult academic…

This article describes the development of a measure of interventionists' competence in implementing culturally responsive multitiered systems of support (MTSS) practices. We ran an exploratory factor analysis (EFA) on a 30-question survey that measured the multicultural competence of 651 school counselors and psychologists in MTSS implementation.…

This study focused on the development of the Problem-Solving Team Effectiveness Scale, a measure used by practitioners to assess the professional learning of a problem-solving team (PST) engaging in the technical aspects of intervention selection, implementation, and evaluation. Several best practices by PSTs were initially identified through a…

The aim was to examine the theoretical constructs and psychometric structure of the Protective Behavioural Strategies Scale (PBSS). Exploratory and confirmatory factor analysis (EFA, CFA) were conducted on data from two studies. Only data from registered university students (18-25 years) were included. EFA supported a two-factor solution for the…

The illness perception questionnaire (IPQ) and its revision (IPQ-R) measure perceptions about health-related diagnoses and the influence of cognitions on coping. In this study, the factor structure of a version revised for use with autism spectrum disorder (ASD) was investigated with a sample of parents (n = 361) whose children have ASD.…

Objective: This study examined the factor structure and psychometric properties of the Urban Hassles Index (UHI). Method: Exploratory factor analyses (EFAs) were conducted via principal axis factoring extraction method. Confirmatory factor analyses were conducted to evaluate the fit of the EFA-derived model using the weighted least squares…

Background: There is a relative lack of measures tailored to the study of fathers of children with developmental challenges (DCs). The goal of the current study was to create and validate a brief measure designed to capture the perceptions and experiences of these fathers. The Fathers of Children with Developmental Challenges (FCDC) questionnaire…
