Over a five-year period the author treated eleven delinquents who were referred by the court; their not keeping appointments was considered a violation of parole. With the early patients in the series the therapist used his traditional psychoanalytically oriented techniques which proved to be ineffective in establishing any therapeutic relationship or in counteracting antisocial behavior. Technique later was modified; a therapeutic activity designed to establish a new and challenging ego-enriching object relationship was used. Favorable response tended to become the rule as shown by developments in therapy and a follow-up study.
