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…

We examined the correlation between interviewer-administered Vineland Adaptive Behavior Scale II (VABS-II) and the parent-rated Adaptive Behavior Assessment System II (ABAS-II) questionnaire in 352 participants (ages 1.5-20.8 years) with autism spectrum disorder (ASD) to determine if ABAS could be used as a screen to reduce the number of VABS…

In this study the Autism Mental Status Exam (AMSE) was validated towards ICD-10 Autism Spectrum Diagnoses (ASD) based on an interview with the Diagnostic Interview for Social and Communication Disorders (DISCO-11) with parent(s)/caregiver(s) in a group of 124 children referred for assessment to a clinical assessment unit for pre-school children.…

This study aimed to assess the validity and normative statistics of the Farsi version of the Social Responsiveness Scale-2 (SRS-2). Among the mainstream elementary schools, 191 boys and 342 girls with a mean age of 9.46 (+ 1.72) years were recruited. Teachers and parents completed the SRS-2. The parents also answered the Social Communication…

This study presents an independent replication and extension of psychometric evidence supporting the "Theory of Mind Inventory" ("ToMI"). Parents of 20 children with ASD (4; 1-6; 7 years; months) and 20 with typical development (3; 1-6; 5), rated their child's theory of mind abilities in everyday situations. Other parent report…

The PEP-R (psychoeducational profile revised) is an instrument that has been used in many countries to assess abilities and formulate treatment programs for children with autism and related developmental disorders. To the end to provide further information on the PEP-R's psychometric properties, a large sample (N = 137) of children presenting…

The TARPA (Training & Assessment of Relational Precursors & Abilities) is a recently developed computer-based protocol for the assessment of a progression of key domains of responding critical to the development of generative language. In the current pilot study, five children with autism were assessed using the TARPA and their score on…

Vineland Adaptive Behavior Scales (VABS) data were examined in a large sample of young children with ASD (n = 290) of varying cognitive levels. IQ was higher than VABS composite score among high functioning children only; the opposite pattern was found in lower IQ subgroups. Profile analysis of VABS domains across cognitive levels demonstrated…

The classification agreement of the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) was examined in 129 children and adolescents (aged 7-18 years) who were evaluated for autism. Participants received a diagnosis of autism or non-autism based on the ADI-R. Linear discriminant analysis revealed…

The study found good concurrent validity when the American Association of Mental Deficiency Adaptive Behavior Scale-School Edition and the Vineland Adaptive Behavior Scales were used with 15 autistic persons aged 8 to 18. (Author/DB)

The psychometric properties of the Vineland Adaptive Behavior Scales Survey Form were studied in a total population of children and adolescents with MR, and in the specific levels of functioning (n=826, age 4-18 years). The original division into (sub)domains, as assigned by the authors, was replicated in the total population and in the mild and…
