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…

Scores from the Child Behavior Checklist and the Client Development Evaluation Report for 67 children and adolescents with mental retardation were examined to evaluate the factorial validity of the instruments. Results found that both instruments were successful in measuring maladaptive behaviors and both yielded two-dimensional representations of…

The psychometric properties of the Motivation Assessment Scale were examined using 90 ratings of different problem behaviors among 86 individuals with mental retardation. Although reliability and internal consistency were generally poor, the results depended upon topographies of problem behavior and methods of calculation. The construct validity…

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)

A study tested the psychometric properties of the Stereotyped Behavior Scale, an empirically developed behavior rating scale for adolescents and adults with mental retardation. Forty-five adults with mental retardation and various rates of stereotypies participated. Results found the scale had high rates of reliability, validity, and interrater…

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)

This study compared responses to a survey on critical social behaviors completed by 79 persons who had prior experience with employees with mental retardation and 59 persons without such experience. Findings revealed that prior experience did not appear to affect ratings though other factors, such as knowing the purpose of the survey, did…

A study used the Questions about Behavior Function Scale to examine the functions of five severe problem behaviors (self-injurious behavior, aggression, stereotypies, pica, and rumination) in 417 institutionalized persons with mental retardation. The most common function for all behaviors except aggression was nonsocial. Aggression was maintained…

Differences in parent and teacher ratings of social-emotional behavior among 198 preschool-age children with developmental delays and 198 without significant developmental problems were examined. The children with developmental delays were rated by both groups as having significantly lower levels of social skills and significantly higher levels of…

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…

A study involving 41 mothers explored the relation of severity of functional impairment on the Childhood Autism Rating Scale-Parent Version to diagnosis, parenting stress, and child age. Children with autism received significantly higher ratings than did children with pervasive developmental disorder-not otherwise specified. Severity predicted…
