Participants in 4 separate weekend encounter groups and matched control Ss were administered pre- and posttests of the Adjective Checklist to determine whether the encounter-group experience would result in increased positive self-concept and confidence and improved social skills and attitudes. Checklist scales were grouped into self-concept-related scales and social-skills scales. Combined data over the 4 experimental groups demonstrated improvement on the 2 concepts, while there was no change in the matched controls over the same time period. Limitations of the study are discussed.
