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 Oman and elsewhere in Arab countries school professionals rely on measures that were developed in Western countries. Measures that assess adaptive behaviour (AB) that have been developed in Western cultures are argued to be culturally bound. Nevertheless, these measures are used elsewhere despite a paucity of data that examine their…

This article is an overview of identification of intellectual disabilities (ID), with a focus on meeting legal and ethical requirements when assessing children from culturally and linguistically diverse backgrounds and those living in poverty. Specific procedures and recommended instruments will be reviewed.

The aim of this study was to examine the internal consistency, inter-respondent reliability, and convergent and divergent validity of the Psychoeducational Profile-third edition Caregiver Report (PEP3-CR) in children with Autism Spectrum Disorders (ASD). We examined the internal consistency on 66 mothers of children with ASD who completed the…

Background: People with severe challenging behaviour are vulnerable to exclusion from local services and removal to out-of-area placements if locally available supported accommodation is insufficient to meet their needs. There are concerns about the high costs and potentially poorer outcomes of out-of-area placements but relatively little is known…

The study assessed the degree to which rehabilitation staff rate severity of maladaptive behaviors on the Americal Association on Mental Deficiency Adaptive Behavior Scale and developed a socially validated revision of the scoring system to allow more accurate classification of mentally retarded individuals as having mild, moderate, or severe…

The strengths of the scales were concentrated in the areas of domain and construct validity, weaknesses in the areas of discriminant validity, interobserver reliability, and decision-making reliability. (DB)

The article describes and critiques two scales (the Vineland Social Maturity Scale and the American Association of Mental Deficiency's Adaptive Behavior Scale - Public School Version) for assessing the adaptive behavior of mentally retarded children. (PHR)

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)

A methodology was described for operationalizing the terms "occasionally" and "frequently" on the Maladaptive Behavior Scale developed from the American Association of Mental Deficiency Adaptive Behavior Scale. Numerical definitions were devised from modal ratings of staff members of 28 rehabilitation agencies. (Author/DB)

The validity of the Adaptive Behavior Scale (ABS) for placement purposes was estimated using as Ss 95 formerly institutionalized retarded persons, 97 institutional residents referred for discharge, and 178 institutional residents. Results suggest that knowledge of an individual's ABS scores would enable a test user to make valid estimates of group…

Forty-five graduate students in special education were asked to rate the items in the violent and destructive behavior domain from part two of the AAMD (American Association of Mental Deficiencies) Adaptive Behavior Scale on a 1 (not very severe) to 4 (extremely severe) scale. (Author/PHR)

The Hand Test and the maladaptive behavior scale of the Adaptive Behavior Scale (ABS) were administered to 78 institutionalized mentally retarded. Significant correlations were found between two purported Hand Test indicators of destructive acting-out behavior and observed violent behavior. (MH)

Presents and discusses a variety of psychometric information pertaining to the American Association of Mental Deficiency (AAMD) Adaptive Behavior Scale. Presents reliability and validity data. Delineates the technical characteristics of the AAMD Adaptive Behavior Scale. (Author/RC)
