There is consistent evidence that a majority of mildly and moderately mentally retarded persons adjust to community environments upon leaving school. Mental age and academic achievement appear not to have a significant influence on adjustment. Other features, including interpersonal skills and social competence do have a strong bearing on community adjustment.In view of this, numerous studies over the past two decades have been conducted to evaluate social skill enhancement strategies. Unfortunately, there are serious limitations to this literature.Specifically, (a) the absence of a conceptual base has resulted in the failure of research to build a comprehensive body of knowledge; (b) training priorities have not been matched to learner characteristics or needs; (c) the social significance of program effects has generally been ignored; (d) independent and dependent variables have not been evaluated and applied with equal precision ; (e) investigators seldom evaluate the generality of effects to other settings, responses, and time; and finally (f) research has not demonstrated that community integration and adjustment can be enhanced through training.
