A representative sample of Hawaii's antisocial adolescents (N = 44) participated in group treatment with and without videotaping. The groups that were videotaped developed an increase in reality-based self/other concept and a more reflective posture regarding their behavior. In addition, they experienced a decrease in self-esteem with reduced emphasis on activity as a means of coping. The use of videotaping in the treatment of antisocial attitudes was most effective in allowing increased reality testing coincident with reduced use of deniat. This effect was enhanced with support provided through the peer group process.Abstract Teaser
