A study investigated the validity of the Questions about Behavioral Function, a checklist designed to assess antecedent behavior, using a sample of 398 persons with mental retardation and self-injurious behavior, aggression, or stereotypies. The checklist was used successfully to derive clear behavioral functions across all three target behaviors.…

Since many problem behaviors of individuals with mental retardation are maintained by multiple functions, this project developed the Functional Assessment for multiple CausaliTy (FACT), an informant-based, forced-choice measure designed to identify the most prominent function associated with the occurrence of problem behaviors. This paper…

A study explored the construct of general anxiety in 69 individuals with severe and profound mental retardation and evaluated the validity of the DASH-II anxiety subscale to determine its value in categorizing individuals with and without anxiety. Results indicated only behavioral symptoms associated with anxiety could be reliably assessed.…

A review found many of the studies that have assessed the efficacy of psychotropic medications with individuals with mental retardation (MR) are methodologically flawed. It details suggestions to improve the quality of medication studies and avoid methodological problems that prevent the scientific advancement of psychopharmacological research…

Studies assessing treatments for severe behavior problems of developmentally delayed persons were reviewed. Procedures used in the 382 studies, published from 1967-1987, were analyzed in terms of problem behaviors, side effects, and treatment methods. Also examined were number of studies reported yearly, maintenance and generalization of effects,…

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…

This study examined three maladaptive behaviors, self-injurious behavior (SIB), stereotypies, and aggression in 36 adults with either autism, pervasive developmental disorder not otherwise specified (PDD-NOS), and mental retardation. Findings indicated that, for all three diagnostic categories, aggression was primarily maintained for attentional…

Two experiments involving 143 and 1,480 individuals with severe and profound mental retardation found that persons with profound mental retardation were more likely to evince sterotypies or self-injury (SIB) compared to their severely impaired counterparts. Those with stereotypies were more likely to present with autism, organicity, and eating…

This article reviews 251 studies evaluating the behavioral treatment of autism from 1980 to 1995. Each study is analyzed for the target behaviors and behavioral techniques that were implemented. Target behaviors included aberrant behaviors, social skills, language, daily living skills, and academic skills. Behavioral techniques are identified as…

A study compared the Aberrant Behavior Checklist (ABC) and the Behavior Problems Inventory (BPI) for assessing the maladaptive behavior of 226 adults, mostly with severe or profound mental retardation. Individuals with elevated BPI scores generally had higher ABC scores, however, the extent of covariation differed across subscales. (Contains…

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…
