What it is

First published in 2005, this self-help workbook introduces ideas associated with acceptance and commitment therapy (ACT). It is intended for general readers and may also be used alongside professional support.

What it covers

The authors discuss ways of relating to difficult thoughts and emotions, acceptance, psychological flexibility and actions connected to personal values. These are ideas and exercises in the approach, not a claim that avoidance explains every person’s distress.

Related research

A 2011 randomised study compared an ACT self-help book in Japanese with a waitlist among 70 Japanese international students in the United States. Participants receiving the book reported better general mental health in that study. A 2012 study compared an ACT self-help volume with a waitlist among 236 school personnel. The accessible abstracts do not identify the books by title, so this entry does not assume they tested this exact edition. Results from these groups and comparisons cannot predict an individual reader’s outcome.

Reading level and limits

The catalogue lists this as an introductory self-help workbook. Research on ACT or on other self-help books does not by itself establish this edition’s effectiveness. This entry is educational and does not offer a diagnosis or individual treatment recommendation.
