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…

Background: In addition to symptoms of neurodevelopmental disorders, functional impairment is crucial to the determination of clinical significance. The aim of this study was to examine partial validity and usefulness of the Strengths and Difficulties Questionnaire's (SDQ) impact supplement (SDQ impact) in measuring functional impairment in…

We used parent-report data from a prospective longitudinal study to better understand the early strengths in written skills often observed in preschoolers on the spectrum. Consistent with previous research, children demonstrated relative strengths in standardized written communication compared to spoken communication scores on the VABS-II. We…

The purpose of this study was to evaluate the reliability, validity, and accuracy of scores from the Intervention Selection Profile--Function (ISP-Function): a brief functional assessment tool founded upon Direct Behavior Rating (DBR) methodology. Participants included 34 teacher-student dyads. Using the ISP-Function, teachers rated the extent to…

Preschool children with autism spectrum disorder (ASD) experience slower development of daily living skills (DLS) that are essential for independent functioning compared to typically developing children. Few studies have examined the trajectories of DLS in preschoolers with ASD and the existing literature has reported conflicting results. This…

The aim of this study is to investigate the applicability of ASK-R among Turkish pre-school children and determine the psychometric properties (validity and reliability) of this scale. This study was conducted with 167 students from different pre-schools in Mugla. Within the aim of the study, three different methods were set down in order to…

Individuals with autism spectrum disorder (ASD) tend to have significant delays in adaptive functioning. In this study, the relationship between adaptive behavior and ASD symptomatology was investigated in minimally verbal, school-aged children with ASD (n = 333). Both the social affect (SA) and restricted and repetitive behavior (RRB) domains…

Inconsistencies of results of foreign language anxiety's effect on advanced learners' language performances have persisted over the years. And little has been known on the relationship between foreign language anxiety and engineering graduate students' language performances. To fill the gap, this study employed a self-report anxiety scale called…

Instructional Technologies and Material Design (ITMD) lesson is a tool that enables Mathematics teacher candidates to design materials for contributing to lasting learning of their students, and use them most effectively. This lesson helps students to activate their creative thinking skills, increase their courage and self-confidence, find…

Background: There is no study to date that has examined the association between history of abuse and adaptive functioning deficits in youth with co-occurring and psychotic disorders or mood disorders. Method: This study used a retrospective chart review of 98 youth under the age of 18 (Mean age = 16.06 years) with co-occurring intellectual…

The researcher investigated if relationships maybe enhanced or deteriorated by the behaviors shown by the principal. The purpose of this correlational…

This study aimed to extract the psychometric properties of a Jordanian version of the Parents Evaluation of Developmental Status: Developmental Milestones (PEDS:DM) to present a psycho-metrically reliable Arabic scale that benefits the Jordanian context as an effective childhood intervention scale. The validity of the scale was achieved in three…

Children with autism spectrum disorder (ASD) tend to receive several related services during their early school years. In this study, we followed 70 preschoolers with ASD and used parent reports to document the intensity of these services over a 4-year period, in relation to children's outcomes in three domains. While behavioral difficulties…

Evidence is accumulating that early intervention can be effective in improving the skills of young children with autism spectrum disorder. However, the science is hampered by the lack of agreed "gold standard" tools for the measurement of progress and outcome. What is required is a reliable, valid, and sensitive measure of change in the…
