Evaluation of multiple component relaxation training with developmentally disabled persons.
Prior studies evaluating the response of developmentally disabled persons to relaxation training procedures are largely limited to case study reports. Most often relaxation training procedures are vaguely described in these studies, and limited outcome measures are employed. In the present comparative group outcome study a specific progressive muscle relaxation training procedure was combined with auditory electromyographic (EMG) biofeedback, modeling, and reinforcement procedures in an attempt to teach relaxation skills to mentally retarded persons (N = 32) who functioned in the profound to mild range. The procedure was effective in reducing experimental group subjects' EMG levels, F (1,28) = 6.39, p less than .05, and activity level as measured with an interval recording behavior rating procedure, F (1,28) = 58.05, p less than .05. No effect was found on peripheral skin temperature. Additionally, no significant difference between the response of low functioning and high functioning subjects was seen indicating that intellectual level and adaptive behavior level failed to predict success in treatment. Scoring on a simple behavioral assessment designed to measure receptive language skills and modeling abilities thought to relate to relaxation training success also failed to correlate with outcome measures. The need to develop other predictors of relaxation training success with a mentally retarded population is discussed.
