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…

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…

There is a need for measures to track symptom change in autism spectrum disorder (ASD). We conducted a validation study on a revised version of the Autism Behavior Inventory (ABI), and a short form (ABI-S). Caregivers of individuals (6-54 years) with confirmed diagnoses of ASD (N = 144) completed the ABI and other rating scales at 4 time points.…

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'…

Given the dearth of technically adequate universal screening tools in the Greek language, the current study sought to examine the psychometric properties of a 67-item universal screener (i.e. Integrated Teacher Rating Form; ITRF), that was originally developed in American English and then translated and implemented in Greek primary schools. The…

The current study evaluates the psychometric properties of the Behavior Rating Inventory of Executive Function (BRIEF) with children with Down syndrome. Caregivers of 84 children with Down syndrome rated their child's behavior with the BRIEF. Teacher ratings were obtained for 57 children. About 40% of children with Down syndrome were reported by…

Restricted repetitive behaviors (RRBs) are a core feature of autism spectrum disorders (ASD) and further occur in intellectual disability (ID), mental disorders (MD), and in typically developed people (TD). There is a need of a valid and reliable measure to record RRBs as transdiagnostic symptom, which captures RRBs heterogeneity and evaluates…

Frequent formative assessment of students' functioning, or progress monitoring, is a critical component of multi-tiered systems of support as data inform data-driven decisions about response to treatment. Progress monitoring tools for students' academic and behavioral functioning are readily available and widely researched; however, despite the…

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'…

The present study examined the relationships between the standardized applied behavior analysis (ABA) direct assessment, the PEAK Comprehensive Assessment (PCA), and established assessments commonly used in educational and clinical settings, including the Childhood Autism Rating Scale - Third Edition (CARS-3), the PDD Behavior Inventory (PDDBI),…

Naturalistic developmental behavioral interventions for young children with autism spectrum disorder share key elements. However, the extent of similarity and overlap in techniques among naturalistic developmental behavioral intervention models has not been quantified, and there is no standardized measure for assessing the implementation of their…

Background: Adaptive skills measures tend to be lengthy. The GO4KIDDS (Great Outcomes for Kids Impacted by Severe Developmental Disabilities; (Journal of Applied Research in Intellectual Disabilities, 58, 2015 and 594)) Brief Adaptive Behaviour Scale was developed to provide a brief assessment of adaptive skills. Our study aimed to examine the…

Restricted and repetitive behavior (RRB) is one of the two key diagnostic features of autism spectrum disorder (ASD). DSM-5 highlights the importance of severity-based diagnostic modifiers assigned on the basis of intensity of needed supports. Therefore, there is a need for available measures that assess the severity of RRB. The repetitive…

Poor reciprocity is a defining feature of an autism spectrum disorder (ASD). In the current study, we examined the reliability and validity of the Interactive Drawing Test (IDT), a new instrument to assess reciprocal behavior. The IDT was administered to children and adolescents with ASD (n = 131) and to a typically developing group (n = 62). The…

Psychometric properties of Romanian translations of the "Behavior Problems Inventory-01" ("BPI-01"; Rojahn, Matson, Lott, Esbensen, & Smalls, 2001) and the "Nisonger Child Behavior Rating Form" ("NCBRF"; Aman, Tasse, Rojahn, & Hammer, 1996) were explored. Respondents completed the instruments for 115…
