Methods of psychotherapeutic intervention with developmentally disabled adolescents are described. The need to consider the cognitive deficits of these individuals is noted. Therapeutic techniques, utilizing primarily a direct teaching approach and involving a great deal of behavioral rehearsal and repetition, are described. Clinical material is presented to illustrate the use of these procedures when problematic behavior stems from a negative self-image, faulty judgement, poor impulse control, or a failure to attain emotional independence. It is suggested that the therapist must focus on the specific problematic aspects of the adolescent's life that are in need of change and should take a position as to the nature and direction of such change.
