This study examined the effectiveness of group assertiveness training with individuals who are mildly and moderately mentally retarded. There were 20 participants with 10 each in the control and the experimental group. Each group received the pretest and posttest measures. The experimental group also received four sessions on assertiveness training adapted from the Elwyn Institute's Personal Adjustment Manual, Volume II, Assertiveness Training. The training was developed for moderately and mildly mentally retarded individuals using these strategies: educational lectures, modeling, role-playing, and feedback. The control group received only the pretest and posttest measures. Assertiveness was measured by using three measures: two questionnaires, one consisting of 25 situational questions eliciting individuals to respond as they would in real life and the Chapman Assertiveness Instrument; and one behavioral observation check off chart. A univariate repeated measures anaLysis of variance was completed for each measure. There were significant results with all three measures indicating that the training was effective in increasing assertiveness.
