Background: Communication impairments are a leading concern for parent caregivers of individuals with rare neurodevelopmental disorders (RNDDs). Clinical trials of disease modifying therapies require valid and responsive outcome measures that are relevant to individuals with RNDDs. Identifying and evaluating current psychometric properties for…

Measures of academic engagement and disruptive behavior in students are strong predictors of social, academic, and lifelong career outcomes. Educators need a measurement tool that is feasible, accurate, and cost-effective in order to identify students who may be in need of additional behavioral support. Direct Behavior Ratings (DBRs) offer a…

Strength-based assessment has achieved acceptance from educational, mental health, and social service professionals as a means to measuring emotional and behavioral strengths of children. Several standardized, norm-referenced tests have been developed to assess these strengths; however, the primary mode of assessment is via informal interviews of…

Behavior analysts frequently use the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess the language and social skills of children with autism in everyday practice and in research. Despite the widespread use of the VB-MAPP, its psychometric characteristics have not been extensively investigated. To provide information…

CDKL5 deficiency disorder (CDD) results in early-onset epilepsy and lifelong cognitive and motor impairments. With no validated measure for communication in CDD, this study evaluated the psychometric properties of the Communication and Symbolic Behavior Scales-Developmental Profile Infant Toddler Checklist (CSBS-DP ITC). Caregivers (n = 150;…

Irrational beliefs (IB) are irrational thinking patterns that limit the interpretation of situations and generate difficulties in daily life. Although there are several instruments to evaluate irrational beliefs, attention to their evaluation in adolescents has been insufficient, and possible gender and cultural differences have been overlooked.…

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…

This study analyzed the psychometric properties of a Chinese version of the teacher-reported Devereux Early Childhood Assessment, Second Edition (DECA-P2) using a sample of 246 children aged between 2 and 6 years old. Confirmatory factor analysis was used to examine its construct validity. Reliability was evaluated based on the internal…

Although 70% of autistic children and young people meet criteria for co-occurring psychiatric conditions, there are few screening measures specifically for autistic individuals. We describe the development and validation of the Assessment of Concerning Behavior (ACB), an instrument co-developed with the autistic community to assess mental health…

Teachers of inclusive early childhood education (ECE) are responsible for monitoring children's social skills achievement, and promoting social play between children with and without special educational needs (SEN). The Teacher Impression Scale (TIS) is an observational assessment developed for this purpose. This study aims to explore the social…

The current study represents the first psychometric evaluation of an expanded version of the Integrated System Teacher Rating Form, which is a German language school-based universal screening measure initially developed to identify students with academic productivity problems and oppositional behavior. The measure was expanded to include…

Minority studies are underrepresented in gifted and talented education programs across the nation and the methods used to identify students for advanced services may be the issue. This study examined the Scales for Identifying Gifted Students (SIGS), a set of nationally normed behavior rating scales, for the purpose of updating the instrument. The…

The Early Learner Curriculum and Achievement Record (ELCAR, Greer et al., 2020) is a criterion-referenced curriculum and assessment of children's development of language and social repertoires from the earliest foundational observing responses to advanced verbal repertoires. The developmental cusps or stages identified in the ELCAR have been…

Introduction: Current measures of restrictive and repetitive behavior (RRB) in people with autism focus on severity and intensity and, to some degree, the global interference of the behavior. In this study we developed the Social Impact of Repetitive Behavior Scale (SIRBS) to capture several different contexts in which repetitive behavior is…

Prevalence estimates suggest that up to 20% of students in schools experience significant internalizing behaviors that impact behavioral, social, or academic functioning. School-based interventions have great potential to promote student mental health; however, validated and feasible brief assessments are needed to progress monitor students'…
