Abstract
This article describes the results of a quantitative analysis of research on the treatment of aggression, self-injury, and property destruction with persons who are developmentally disabled. Fifteen evaluative criteria, including use of functional analysis of behavior, assessment of generalization, maintenance, and change in collateral behaviors, were used in examining 62 experiments. Results indicate significant limitations in methodological rigor and use of "state-of-the-art" behavioral procedures. Conclusions regarding effective treatment are generally consistent with earlier reviews. Discussion focuses on the need for improvements in the design and evaluation of interventions, further research on reinforcement-based interventions, effects of punishment, and treatment of aggression displayed by adults.
