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…

This study used the Scales of Independent Behavior (SIB) and the Social Skills Rating System (SSRS) to examine the relationship between ratings of adaptive behavior and social competence with 208 students in kindergarten through third grade with a variety of disabilities. The study provided evidence for the concurrent criterion-related validity of…

Eighteen adolescents and adults with severe/profound intellectual disability were rated by two staff members using the Motivation Assessment Scale to identify variables maintaining their aggressive behaviors. Analysis of interrater reliability indicated that for some individuals the scale may not represent a feasible alternative to more formal…

Analysis of teacher and parent ratings of 369 children with developmental disabilities on the Nisonger Child Behavior Rating Form provided normative data (means, T scores, and percentiles). Age influenced three of eight subscales on the parent ratings and one subscale on the teacher ratings. Gender did not influence subscale scores. (Author/DB)

This replication study found that only 16 of 55 raters agreed on the category of reinforcement maintaining a disabled individual's self-injurious behavior after using the Motivation Assessment Scale. Additionally, only 15 percent of the correlation coefficients obtained were above 80 percent, and none of the reliability scores was above 80…

The Reiss Screen for Maladaptive Behavior, an instrument used to identify persons with both mental retardation and mental health problems, was evaluated with 89 Dutch adults having mental retardation. Reliability and validity of the scale and relationships with subject characteristics were examined. (Author/DB)

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. (Author/DB)

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…

The applicability of the Children's Depression Inventory (CDI) (in the informant-rating version) to mentally retarded adults was evaluated with 798 individuals. Evaluation of internal consistency, interrater reliability, factor analysis, and effects of age, sex, and degree of mental retardation indicated that the CDI is suitable as a diagnostic…

Teachers completed the Connors' Teacher Rating Scale on 100 boys (ages 6-8) who either had attention deficit-hyperactivity disorder (ADHD), mental retardation, both ADHD and mental retardation, or no disability. Children with mental retardation were generally more anxious than normal peers, but there were few differences between the normal IQ ADHD…

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…

This study delineated procedures for cross-cultural adaptation and operationalization of adaptive behavior in individuals with mental retardation, culturally adapted the Vineland Adaptive Behavior Scale, and investigated the validity of the resulting instrument. The study concluded that the domain of adaptive behavior can be successfully applied…

Social skills and levels of inappropriate assertiveness/impulsiveness were assessed using the Matson Evaluation of Social Skills with Youngsters, with 17 autistic children (ages 2-21) and 17 matched nonautistic children. Significant differences in both appropriate and inappropriate social behaviors were found. Results suggest the importance of…

The Adolescent Behavior Checklist is a self-report scale used to assess the likelihood that an adolescent with mild mental retardation or borderline intelligence has a diagnosable mental illness. The scale was found to be more effective in screening in adolescents with psychiatric diagnoses than in screening out adolescents without psychiatric…
