Parents of 601 children and adolescents with mental retardation rated their children on the Aberrant Behavior Checklist-Community (ABC). Factor analysis revealed a factor structure similar to the original ABC but without the inappropriate speech factor. Analysis of subject variables revealed main effects for gender, age, and classroom assignment…

The Reiss Screen for Maladaptive Behavior was factor analyzed in 2 institutional samples and 1 community sample of persons with mental retardation (total n=353). Factor analysis revealed no strong justification for the instrument's seven scales. An alternative three-factor solution, comprising intrapersonal maladaptive behavior, psychotic…

The original factor structure of the Aberrant Behavior Checklist was cross-validated with a U.S. sample of 470 persons with moderate to profound mental retardation (27 percent nonambulatory). Results replicated previous findings, suggesting that the original five factors (irritability, lethargy, stereotypic behavior, hyperactivity, and…

Parent and teacher ratings on the Aberrant Behavior Checklist with an outpatient sample of 110 children, adolescents, and young adults with mental retardation found that the 5-factor structure of both parent and teacher data corresponded very well with the 5 factors originally obtained from staff ratings of mentally retarded inpatients.

Analysis of data from the Behaviour Disorder Scale for 405 adults and adolescents with intellectual disability revealed that subjects exhibited a mean of 14 problem behaviors per person. Factor analysis identified two general syndromes (a conduct syndrome and an emotional syndrome), raising the possibility of dealing with sets of problem behaviors…

The Child Behavior Rating Form (CBRF) was adapted for use with children having mental retardation and was named the Nisonger CBRF. Independent factor analyses of parent and teacher ratings for 369 children produced 2 Social Competence subscales and 6 Problem Behavior subscales. Internal consistency was generally high and parent-teacher agreement…

Teacher ratings on the Aberrant Behavior Checklist were collected on 666 students with mental retardation attending special classes. Classroom placement and age had significant effects on subscale scores, whereas sex failed to affect ratings. The study concludes that the original scoring method, developed for individuals in residential facilities,…

Evaluation of the factor validity and reliability of the Aberrant Behavior Checklist (Japanese version) with 322 subjects (mean age 30) with moderate to profound mental retardation found most items loading on the same factors as in the original factor solution, high coefficient alphas across 5 subscales, high test-retest reliability, and…

Psychometric evaluation of the Preschool and Kindergarten Behavior Scales (PKBS) is reported. Factor analyses indicated the presence of a stable factor structure for both social skills and problem behaviors scales. Reliability studies indicated the PKBS has adequate-to-strong stability. Explorations of within-scale relationships yielded evidence…

This report presents results from three research studies that were designed to explore both the definition and the structure of the adaptive behavior construct. The first study investigated the structure of adaptive behavior as a function of age, developmental level, and type of handicap through an exploratory factor analysis of both the…
