Fifty staff working with adults with mental retardation rated potentially challenging behaviors in terms of: (1) whether they thought the behaviors were challenging, and (2) whether the behaviors should be the focus of intervention. Results found that staff were less likely to identify as challenging those behaviors having negative effects on…

Results of evaluating effects of fenfluramine on 21 maladaptive behaviors in 20 autistic individuals (from 9 to 30 years old) over a 9-month period using a double-blind, cross-over, placebo-controlled design indicated no significant reductions in maladaptive behaviors and the presence of negative side effects.

Data were summarized from 1,841 sessions involving 10 subjects with mental retardation who participated in a number of experiments over a 10-year research program concerning dietary influences on ruminating. Relationships were found between amount of food consumed and rumination. Satiation feeding resulted in substantial decreases in postmeal…

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 efficacy of the atypical antipsychotic risperidone was evaluated in the treatment of aberrant behavior (e.g., aggression, self-injury) in 20 individuals with developmental disabilities. The study, a double-blind crossover design, identified 50 percent of participants as responders. Naturalistic observations of five participants showed that…

In this study with three children (ages four and five) with severe developmental disabilities and aberrant behavior maintained by tangible positive reinforcement, noncontingent reinforcement, and differential reinforcement of alternative behavior were found to decrease the frequency of aberrant behavior while strengthening mands. (Author/DB)

An attempt to replicate previous studies showing a positive effect of antecedent exercise on problem behavior found no consistent changes in problem behaviors for six adults with severe mental retardation exposed to either daily jogging or leisure games (attention control). (Author/DB)

This commentary outlines considerations in assessing (and programing for) social validity to attain results that are valued by client audiences. It discusses the objectives and contexts of several types of social validation, procedures for conducting a social validation, and questions addressed by researchers in assessing social validity.

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)

The study assessed whether 4 students (ages 9-13) with severe autistic disabilities could learn to use a self-management treatment package to reduce stereotypic behavior. Use of the procedures greatly reduced levels of stereotypic behavior. Improvement also occurred for extended periods of time in new settings without the presence of a treatment…

Functional analysis conducted during a 90-minute evaluation session identified maintaining variables for aggressive behavior and an alternative replacement response in 3 individuals with severe handicaps. During a subsequent contingency reversal phase, aggressive behavior was substantially reduced and alternative behavior increased. Results…

A functional assessment of tantrum behaviors of two students (ages seven and nine) with severe mental retardation found that the function of the behavior was to gain attention rather than to avoid or escape demands. Intervention, based on the positive reinforcement hypothesis, resulted in a substantial reduction of tantrums for both subjects.…

Comparison of the relative effectiveness of part versus whole teaching strategies for students (N=24) with moderate and severe mental retardation found positive (but not significant) effects favoring the part method. Students taught by the part method exhibited less excess behavior than did students taught by the whole method. (Author/DB)

The efficacy of the serotonin uptake inhibitor clomipramine in treatment of self-injurious behavior (SIB) was tested using a double-blind, placebo-controlled crossover trial in eight adults with severe/profound mental retardation. Clomipramine treatment was associated with significant improvement in the frequency of SIB, SIB intensity, and…

The article reviewed research on professionals', consumers', and others' judgments of the restrictiveness, social acceptability, and estimated frequency of use of procedures to decrease problem behaviors of disabled persons. Most respondents agreed that more restrictive procedures should be used as a last resort and that less restrictive…
