Making behavioral activation more behavioral.

Behavioral Activation, an efficacious treatment for depression, presents a behavioral theory of depression--emphasizing the need for clients to contact positive reinforcement--and a set of therapeutic techniques--emphasizing provision of instructions rather than therapeutic provision of reinforcement. An integration of Behavioral Activation with another behavioral treatment, Functional Analytic Psychotherapy, addresses this mismatch. Functional Analytic Psychotherapy provides a process for the therapeutic provision of immediate and natural reinforcement. This article presents this integration and offers theoretical and practical therapist guidelines on its application. Although the integration is largely theoretical, empirical data are presented in its support when available. The article ends with a discussion of future research directions.
