This breakout session provides a practical and clinically grounded exploration of Acceptance and Commitment Therapy (ACT) and its application across treatment settings. Participants will examine the theoretical foundations of ACT, including Relational Frame Theory and mindfulness-based interventions, and learn how these frameworks inform case conceptualization and treatment planning. The session will focus on strengthening psychological flexibility, the central mechanism of change in ACT, and understanding how experiential avoidance contributes to client suffering. Through discussion and applied examples, attendees will explore how to integrate the six core processes of ACT into real-world clinical contexts. Participants will leave with actionable strategies to help clients accept painful experiences, clarify values, and move toward more vital, purposeful, and value-driven lives. Session Objectives: Describe the theoretical models underlying ACT, including relational frame theory and mindfulness-based interventions, as they relate to case conceptualization Use skills in mindfulness to accept the painful aspects of clients’ lives while at the same time reducing the experiential avoidance that causes suffering in clients Show how the lack of “psychological flexibility” contributes to a client’s suffering Articulate the application of the six core processes of ACT in unique clinical contexts Articulate how ACT can be used to empower clients live a more vital and value-driven life
