14 Best Books on Acceptance and Commitment Therapy

Acceptance and Commitment Therapy BooksAcceptance and Commitment Therapy, or ACT (pronounced “act”), is an evidence-based psychological therapy that blends Cognitive-Behavioral, humanistic, and mindfulness-based approaches to treatment.

ACT is a collaborative coaching intervention based on a therapeutic model called the hexaflex, which is supported by relational frame theory.

The best way to learn about ACT is to take an experiential skills training course and get supervision. However, there is a great deal you can learn from reading books about Acceptance and Commitment Therapy too.

This article reviews our 14 favorite ACT books and includes links to relevant resources so that you can kick-start your ACT education.

14 Top Acceptance and Commitment Therapy Books

This article reviews the top 14 ACT books and has been broken down into sections so you can head straight to the type of books that interest you most.

As a seasoned ACT practitioner myself, I’ve chosen the following books to include classic texts for individuals, groups, beginners, and more advanced practitioners; self-help books for clients; and ACT workbooks for specific client groups.

The names of a few well-known authors might jump out at you, such as Professor Steven Hayes and Russ Harris.

Russ Harris, an author, trainer, and expert in ACT, has written several books, including The Happiness Trap and ACT Made Simple, that offer practical guidance on how to apply the principles of ACT in your life. Harris is also the founder of The Happiness Trap website, which provides resources and information on ACT.

In turn, the workbooks address specific problems where ACT can be most effectively applied.

But before I jump into the selection of Acceptance and Commitment Therapy books, you might want to brush up on ACT with this extensive selection of related articles:

7 Best ACT Therapy Books for Practitioners

These are my top seven must-reads for any ACT practitioner, whether you are a beginner or more experienced. The latest edition of each text (as of writing) is discussed, and recent revisions based on the up-to-date research evidence are explained.

1. ACT Made Simple: An Easy-to-Read Primer on Acceptance and Commitment Therapy – Russ Harris

ACT Made Simple

Russ Harris is a medical doctor turned ACT therapist who is probably best known for his writing on ACT for a popular audience. Harris writes with clarity and humor, making his teachings both entertaining and easy to implement.

Now fully revised and updated, the second edition of ACT Made Simple includes new chapters on self-compassion, flexible perspective taking, and working with trauma. Harris breaks down the six core principles underpinning the ACT hexaflex into simple ideas that make it easy for a new practitioner to grasp and implement.

The book includes exercises, ACT metaphors, scripts, and worksheets you can use with your clients. It provides a session-by-session guide to implementing ACT, which is illustrated with transcripts of therapy sessions. Finally, it provides guidance for creating your own ACT techniques and practical tips for overcoming “therapy roadblocks.”

If you are curious about this book, consider accessing the first two chapters, which are posted on Harris’s website for free.

2. Acceptance and Commitment Therapy: The Process and Practice of Mindful Change – Steven C. Hayes, Kirk D. Strosahl, and Kelly G. Wilson

Acceptance and Commitment Therapy, Second Edition

This is a classic written by the founder of ACT, Professor Steven C. Hayes, and two of his colleagues.

The book begins with an explanation of relational frame theory, which is the philosophical foundation of the entire approach. The text is intellectually dense and recommended for those looking for an academic grounding in the philosophy behind ACT, rather than an introductory guide.

The new edition refers to the huge advances that have been made in clinical applications, theory building, and research.

ACT focuses on enhancing psychological flexibility, and this revised edition includes more detailed explanations of mindfulness, the therapeutic relationship, and case formulation. It is especially aimed at clinicians interested in the moment-by-moment process of ACT therapy.

3. The Essential Guide to the ACT Matrix: A Step-by-Step Approach to Using the ACT Matrix Model in Clinical Practice – Kevin L. Polk, Benjamin Schoendorff, Mark Webster, and Fabian O. Olaz

The Essential Guide to the ACT Matrix

This book takes the core concepts of Acceptance and Commitment Therapy and presents them in a simple way to help you explain to your clients how ACT works. It’s a highly accessible book.

The ACT matrix fuses the six core principles of ACT into a simplified approach that focuses on clients’ behaviors as either workable or unworkable.

This innovative approach to ACT can apply to a range of contexts, especially when clients seem resistant or unmotivated to participate. The matrix was originally developed for group settings but is now used to work with individuals too.

The emphasis is on learning to track where certain behaviors take the client: either toward or away from their personal values. Generally, the ACT matrix helps clients align with what’s important to them (“toward” moves) by becoming more aware of avoidance behaviors (“away” moves) that block the development of psychological flexibility.

This book on the ACT matrix is a great guide for practitioners who want to streamline their therapeutic approach.

4. The Big Book of ACT Metaphors: A Practitioner’s Guide to Experiential Exercises and Metaphors in Acceptance and Commitment Therapy – Jill A. Stoddard and Niloofar Afari

The Big Book of ACT Metaphors

ACT practitioners often use metaphors to explain concepts in a therapy session. Metaphors help to cut through literality, allowing a more visceral and emotional experience of ACT. By drawing on imagery and visualization, concepts stick better.

Many practitioners have created metaphors that have been widely shared for free. However, metaphors can become stale. This resource book has been written by two ACT researchers to provide an A-to-Z library of new ACT metaphors and other experiential exercises to help perfect these powerful tools.

The authors explain the six core ACT processes, detail how to organize group sessions, and include a range of activities that facilitate cooperation between group members. Comprehensive worksheets are also provided.

The book explains how the benefits of the ACT approach can be enhanced in a group setting because there are more participants in the exercises. Group work also leads to increased accountability and enables clients to play an active role in their own treatment while observing how ACT works for others.

The book includes tips for applying ACT to several group work scenarios, such as inpatient group therapy, outpatient programs, and community self-help groups. The detailed exercises and outlines of group activities provide everything you need to start using ACT in group settings.

The second edition includes important revisions based on new research in contextual behavioral science. These recent developments are reflected in the new and updated exercises and references included.

The book guides practitioners on how to use the ACT hexaflex and six core processes as a diagnostic tool, for case conceptualization, and for structuring treatments for clients. The revised edition includes updated information on process coaching, an increased focus on functional analysis, and downloadable role-play examples of the ACT processes in action.

The new workbook exercises can help you improve clients’ psychological flexibility and help them lead more fulfilled lives. This is an especially useful book for practitioners seeking a deeper understanding of the broader field of contextual behavioral science.

By developing a willingness to accept and experience all your emotions fully without letting them hijack your life, you’ll learn to let go of your struggle against pain and commit to acting in ways that fulfill your personal values.

Anxiety is one of the most prevalent mental health challenges people face today. Although many try to manage anxiety by attempting to avoid it altogether, this often makes it worse.

Clinicians can use this accessible and entertaining workbook and as a self-help resource. Readers will learn how to transform anxiety and create a richer and more fulfilling life for themselves and/or their clients using innovative ACT techniques.
