The advisability of granting a probation period to an adolescent offender on condition that he accept psychotherapy, although against his will, is affirmed in a case study by Odenwald. A sullen negativistic seventeen-year-old juvenile delinquent found, in spite of his suspicions and hostility, such emotional relief through psychiatric interviews that a marked change in behavior set in. After the probation period was over and treatment had been suspended, he continued to show beneficial results and maintained a good external adjustment. Eventually he developed an agoraphobia that led him voluntarily to seek a renewal of treatment. The case is of interest in demonstrating how the latent desire for recovery may be activated in the course of work with psychopathic personalities.
