This study investigates the change in social self-concept among adolescents participating in a summer program for the gifted. Participants include 140 gifted students who had completed the 7th through 10th grade during the previous academic year. Social self-concept was measured at the beginning and end of the summer camp using the same-sex peer relations and the opposite-sex peer relations subscales of the Self-Description Questionnaire II (Marsh, 1990). Results indicate both males and females experienced an increase in their perceived same-sex peer relations and their perceived opposite-sex peer relations over the course of the summer program. Conclusions and implications for education policy are discussed.
