This training will introduce the guiding principles and core processes of Acceptance and Commitment Therapy (ACT), including discussion of the goals of ACT and how they overlap with and differ from the goals of other cognitive-behavioral therapies. Participants will be guided through experiential exercises that can later be used with clients, including activities focused on values clarification, cognitive defusion, and acceptance. The training will also explore how techniques from ACT can enhance clinical work with homeless-experienced and justice-involved clients. Participants will learn how tools and interventions from ACT can be used to navigate challenges such as recovering from traumatic experiences, reducing substance use, navigating major transitions (e.g., re-entry, obtaining housing), building supportive relationships, and increasing alignment with personal values. Participants will leave the training with a set of ACT-informed strategies that can be incorporated into psychotherapy, case management, recovery coaching, and other service contexts.
