This study compared the occurrence and characteristics of self-stimulatory behaviors of 5 children with developmental delays and 10 nondisabled children (matched for either mental or chronological age). Few differences were found between groups in percentage of time spent in self-stimulatory behavior, the variety of such behaviors, the speed at…

The diets of three individuals with profound mental retardation and histories of coprophagia (ingestion of feces) were supplemented with a nutritionally complete elemental diet called Vivonex, resulting in decreases in the frequency of coprophagia in all three cases. (DB)

The effects of two levels of exercise (walking versus jogging) in suppressing the self-stimulatory behavior during academic programming of a 5-year-old boy with autism were examined. Decreased physical self-stimulation and "out of seat" behavior were found only for the jogging condition. Sharp reductions in these behaviors did not return…

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 oral opiate, naltrexone, was used in a double-blind placebo-controlled study with two young profoundly mentally adults who exhibited intractable self-injurious behavior. No measurable effects on the self-injurious behavior were observed. (Author/DB)

A survey of 39 psychologists at a state school for mentally retarded persons assessed the prevalence of self-restraint, self-injurious behavior (SIB) and other maladaptive behaviors. Results indicated that almost all clients engaging in self-restraint also engaged in self-injurious behavior. (Author/DB)

Data concerning maladaptive behavior obtained on a sample of persons (n=8255) with mild to profound mental retardation and aged from birth to 98 years were factor analyzed resulting in identification of 2 principal factors for children, 3 for adolescents and young adults, and three and 4 for middle and older adults, with level of retardation also…

This study evaluated a method for assessing the behavioral function of severe self-injury in four adults with severe/profound mental retardation. Initial assessment included analyzing within-session trends and fluctuations in rates of self-injury by plotting the frequency within each minute of the session. (DB)

In this preliminary study, three parents who requested outpatient services for treatment of developmentally disabled children's problem behavior were taught to implement multiple treatment components. Therapists employed the most cost-efficient method first (i.e., written and verbal instructions) to teach prescribed behavior management strategies.…

A brief functional analysis indicated that the object mouthing of a young girl diagnosed with autism was maintained independent of social consequences. Separate and combined effects of response blocking and non-contingent reinforcement were then evaluated as treatments. Although both interventions were unsuccessful when implemented separately,…

Analysis of 117 research articles reporting use of behavioral interventions with single subjects with autism concluded that behavioral treatments are effective in reducing problematic behaviors. Type of target behavior and type of treatment did not moderate average treatment effect. Reliability of observation, number of treatment data points, and…

This study compared guided compliance versus time out as a method of promoting child adherence to adult requests. Time out effected larger increases in percentage compliance among four of five participating children (ages three to six years) with mild developmental disabilities. (Author/DB)

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…

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…

This case study focused on an adult with severe disabilities and multiple problem behaviors fitting a pattern of behavioral escalation. Functional assessment indicated that use of rule statements by the teacher was related to occurrence and escalation of problem behaviors. Elimination of rule statements was an effective instructional intervention…
