The ease of delivery and application of behavioral procedures allowed parents and other caregivers to become meaningfully involved in the clinical process, and so facilitated therapy gains and the maintenance and generalization of those gains. Perhaps the most significant change in behavior therapy in the 1970s was the move beyond interventions derived strictly from learning theories to applications based on knowledge from a variety of psycho­ logical research areas. The cognitive mediational activities of the client have received special attention, and this book presents the conceptual, methodological, and clinical issues in contemporary cognitive behavior therapy with children.
