The use of metaphors is fundamental in the successful delivery of acceptance and commitment therapy (ACT), but for many ACT therapists, they often become over-used, stale, and less effective as time wears on. The Big Book of ACT Metaphors is an essential A-Z resource guide that includes new metaphors and experiential exercises to help promote client acceptance, defusion from troubling thoughts, and values-based action. The book also includes scripts tailored to different client populations. Whether treating a client with anxiety, depression, trauma, or an eating disorder, this book will provide mental health professionals with the skills needed to improve lives, one exercise at a time.
