This course provides behavior analysts with a comprehensive, practical framework for integrating Acceptance and Commitment Therapy (ACT) into applied behavior analysis. Grounded in contextual behavioral science and Relational Frame Theory (RFT), participants will move beyond theory to develop real-world clinical skills. Across 14 weeks, learners will explore the ACT Hexaflex, adapt interventions for diverse populations, write measurable goals, design data systems, and address ethical, cultural, and supervisory considerations. Each module builds toward advanced case conceptualization and system-wide implementation. Through applied assignments, case mapping, and expert-led instruction, participants will learn how to target psychological flexibility as a meaningful treatment outcome. This course is designed for professionals seeking to expand their clinical impact while maintaining a strong behavior analytic foundation.
