Abstract
Parents of mentally retarded children rated the acceptability of four treatment techniques: differential reinforcement of incompatible behavior (DRI), over correction, time-out, and drug therapy. The treatments were described in a clinical case study of a mentally retarded child; acceptability was evaluated using the Treatment Evaluation Inventory and the Semantic Differential. The most acceptable treatment was DRI followed by overcorrection. Time-out and drug therapy proved least acceptable but were not rated significantly different from each other. This study extends findings from previous research on treatment accept- ability to parents of mentally retarded children, which is important because they are often involved in choices and implementation of treatment alternatives for their children.
