Overview
This book empowers both new and seasoned clinicians to enhance their proficiency in acceptance and commitment therapy. Acceptance and commitment therapy (ACT) is rooted in a behavioral and contextual understanding of human suffering, with language and cognition playing a central role. While the capacity for language enables creativity, planning, and connection, it also allows humans to engage in internal dialogue that can generate and prolong distress, increasing suffering. ACT is a psychological intervention that aims to increase psychological flexibility—the ability to stay present, open up to experience, and take action guided by deeply held values. With their book, the authors aim to help newer and seasoned clinicians understand the underpinnings of ACT, and learn and develop skills in implementing ACT as an integrated therapy. Deliberate practice of ACT is designed to guide readers through learning ACT in a structured, step-by-step way—from core theory and model to applied clinical skills. The book is organized into a series of parts that build on one another, each laying the foundation for the next to support deep, integrated learning. Chapters address basic, intermediate, and advanced skills development, complemented with engaging personal and clinical practice exercises to help readers understand the process both conceptually and experientially. The book offers theory and skills building on a personal level by inviting readers to examine the impact of ACT concepts on their own experience before applying them in session, and to practice exploring the full model with feedback from students and other professionals interested in learning ACT.

Luoma, PhD, CEO, Portland Psychotherapy, and Senior Scientist, Portland Institute for Psychedelic Science, Portland, OR ""This is the ACT book I wish I'd started with—a smart, well-written guide that uses simple, clear language to lay out the what, when, and why of ACT interventions. It's packed with genuinely useful exercises that bring the concepts to life in practical ways, while perfectly illuminating ACT's philosophy, theory, and six core processes. An ideal introduction for anyone beginning to learn ACT or wanting to deepen their understanding of the approach."" - Miranda Morris, PhD, Peer Reviewed ACT Trainer, Past President, Association for Contextual Behavioral Science, ACBS Fellow, and Founder, True North Therapy and Training, Bethesda, MD
