prescribed drugs as treatment for disorders of emotion or behavior. Unfortunately, further studies indicate that only one or 2 out of every 10 clients receiving medication are determined to be "responders," such that some thera­ peutic benefit is derived from their drug treatment. As noted by the title, the single major thrust of this volume is to review approaches to the treatment of behavior disorders in persons with mental retardation from a nondrug perspective. This requires the presentation of a wide range of material on treatment: basic behavior modification programming, cognitive-behavioral strategies, habilitative approaches, counseling and psychotherapy, designing therapeutic living environments, managing medical factors bearing relevance to emotional illness, intervening with families, training special education teachers and direct care staff, and supplying information on the client's rights to obtain treatment in the least restrictive and least intrusive manner.
