This paper describes the initial phase of acceptance and commitment therapy (ACT). The paper begins with a review of ACT’s theoretical orientation. Basic empirical support for ACT and its model is covered. A case description follows that highlights the initial phases of ACT. The paper concludes with practical recommendations for starting therapy using ACT.

Clinical impact statement:

Question: The goal of this paper is to present the manner in which ACT is initiated. Findings: There are specific theoretical elements of ACT that suggest certain approaches be taken at the beginning of therapy. Meaning: Before starting ACT with a new client, therapists should be familiar with the theoretical orientation of the therapy and the techniques needed to imitate it. Next Steps: Research on how to train these skills appears needed.
