Abstract
Sixteen moderately and mildly retarded human adults were selected from a group residential facility and randomly assigned to experimental and control groups. The experimental group received a 12-session interpersonal skills training program consisting of instruction in the following areas: introductions and small talk; asking for help; differing with others; and handling criticism. The social skills instructional package included verbal instruction, modeling, role playing, feedback, contingent incentives and homework. Moderately and mildly retarded adults acquired new social skills as evidenced by performance on a situation role play assessment. These gains generalized to untrained role play situations but did not result in significant group differences when assessed in a more natural setting.
