Acceptance and Commitment Therapy (ACT; Hayes, Strosahl, & Wilson, 1999) has been found effective in treating a wide number of psychological conditions affecting adults. To date, however, little research has been done on the use of ACT with youth and parents. Few efforts have been made at summarizing the literature that does exist. This article, therefore, is a review of empirical and theoretical work with these populations. Online databases, ACT-related websites, and personal communication were used to collect information about published and unpublished, ongoing work. Recommendations for future research are also mentioned. (Contains 1 table.)
