Zettle, R. D., & Hayes, S. C. (2002). Brief ACT treatment of depression. In F. Bond & W. Dryden (Eds.), Handbook of Brief Cognitive Behaviour Therapy (pp. 35-54). Chichester, England: Wiley.
The purpose of this chapter is to discuss the short-term treatment of depression with acceptance and commitment therapy (ACT—pronounced as one word, “act,” not A-C-T). We will first consider the psychological contexts that seem to relate to the initiation, exacerbation, maintenance, and alleviation of depression. We will then present a brief overview of the principles and techniques of ACT, and show how they attempt to modify the contexts within which depression occurs. Finally we will review the literature on the impact of ACT on depression.
