Group psychotherapy with disturbed undersocialized adolescents requires modification of traditional group psychotherapy methods. The effectiveness of a structured, brief video-tape feedback and discussion on group psychotherapy process with this population was studied by an analysis of detailed ratings of each "statement", or process unit; in randomly selected videotapes from a control and experimental group during a nine-month period. Significant differences in level of intimacy of verbal content and in frequency of feedback about behavior in content indicate that this technique is effective in facilitating group psychotherapy goals.
