In 1986 the first research study investigating Acceptance and Commitment Therapy (ACT) was published. It aimed to determine if an early conceptualization of the ACT model could be used to treat depression. Since this seminal study, further investigations have been conducted across every imaginable psychological issue and the rate at which this research has emerged is impressive. This book describes the research journey that ACT has taken in the past 30 years. It also suggests, in light of the progress that has already been made, how ACT research should move forward in the coming decades.

“Hooper and Larsson aim to describe the research journey of ACT so far and map out directions for future research. … The clear and logical structure of the book certainly helps the reader to use it in this way. I think the book is likely to appeal to both researchers and clinicians, whether they are experienced in ACT or are just curious to learn more about the approach and the current state of the evidence base.” (Pamela Jacobsen, The Journal of Critical Psychology, Counselling and Psychotherapy, Vol. 16 (3), September, 2016)
