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…

Factor analyses of ratings received by 617 patients in a state hospital for the mentally retarded, concerning 26 problem behaviors, indicated that five factors describe the behaviors. (Author)

Thirty-three psychologists with experience in mental retardation rated the 452 statements contained in Part Two of the Adaptive Behavior Scale (used to assess the mentally retarded) along a continuum of severity. (Author/DLS)

Three Scales of imitative behavior (nonverbal, vocal, and verbal) were administered to 28 Down's syndrome Ss (mean age 26 years) and 56 Ss (mean age 26.8 years) with other diagnoses in order to test the hypothesis that Down's syndrome individuals "are outstanding in their mimicry". (Author/PHR)

A structured behavior-observation instrument for studying supervision (mode of communication, function, content, tone, location, and target) had high reliability when used with five administrators in schools for severely mentally retarded children. Supervisors generally spent more time on administrative than professional or teaching-related…

Teachers and parents completed the Adaptive Behavior Scale-School Edition and the Adaptive Behavior Inventory for Children, and 57 mildly retarded and slow-learning students completed the Children's Adaptive Behavior Scale. Results indicated higher ratings for the slow-learner group on all three measures. Parents rated students higher than did…

The development of the Wisconsin Behavior Rating Scale was examined and the hypothesis supported that the extensive content of the scale as well as its arrangement of items with progressive difficulty would be effective in discriminating a rather homogeneous group of individuals functioning between 0 and 4 years. (Author/CL)

In the study based on scores from 221 mentally retarded residents, the individual items in the first 13 Part Two domains of the American Association on Mental Deficiency Adaptive Behavior Scale were weighted for the perceived severity of the behavior they represent. (Author/SW)

The Minnesota Developmental Programming System Behavioral Scales, Alternate Form C, designed to assess adaptive behavior of profoundly developmentally disabled individuals, was evaluated using data from 3,487 individuals. (Author/CL)

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…

The development of a scale to assess drug and other treatment effects on severely mentally retarded individuals is described. Separate factor analyses of the data from two samples resulted in a five-factor scale: (1) Irritability, Agitation, Crying; (2) Lethargy, Social Withdrawal; (3) Stereotypic Behavior; (4) Hyperactivity, Noncompliance; and…

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)
