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…

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…

A brief negative-reinforcement assessment was conducted with five children (ages 4 to 14) with developmental disabilities with severe destructive behavior. Children were trained to engage in an escape response and were presented with a variety of stimuli. For each child, several stimuli were identified that may serve as effective negative…

A study examined the effects of progressive relaxation training on the disruptive behaviors of a 12-year-old boy with autism. The participant acquired progressive relaxation skills, displayed more relaxed behavior after performing the procedures, and showed a decrease in the duration of his disruptive behavior upon completing progressive…

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…

Three severely mentally retarded adolescents who exhibited repetitive hand movements were assessed during baseline (reinforcement for on-task behavior) and sensory change (rings on fingers of both hands, rings and reinforcement, and faded rings) conditions. Sensory change effectively reduced the target responses for up to four hours. (Author/JDD)

This study analyzed effects of repetitive task size on rate of responding and behavior of five adolescents with autism and mental retardation. Compared to large-task conditions, small-task conditions resulted in higher on-task behavior and better work-related behavior for all participants and higher work rate for four participants. (Author/PB)

Time-based lag sequential analyses were conducted on 23 topographies of challenging behavior shown by 5 young people with severe mental retardation across 2 settings. Potential behavioral functions were identified for 21 of the 23 behaviors. Response classes were identified for four participants. Cross-validation with brief experimental analyses…

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…

A follow-up study of 26 children (ages 5-13) with attention deficit hyperactivity disorder and low intelligence found that children identified with both characteristics have significant behavioral and emotional problems while in their early adolescence. A significant minority had problems at school and with the law. (CR)

This study of three individuals (ages 12-14) with profound mental retardation found that visual screening was more effective than thioridazine in reducing stereotypy and increasing social behavior. Thioridazine produced modest stereotypy reductions and minor social behavior increases, with a higher dose slightly more effective than a lower dose…

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)

Fifty children and adolescents with affective disorders and mental retardation admitted to a psychiatric inpatient unit were compared with 50 inpatients without depression. Behavioral symptoms occurred significantly more often in the affective group than in the comparison group. The behavioral presentation of affective symptoms in children and…
