The pages below list published ACT-related research studies for specific health problems that are available on the website as of July 2008. Empirical studies listed include ACT outcome studies, case studies, correlational research and micro/component studies. The literature is moving quickly and it takes a while to update pages like this. For a more detailed list of outcome studies and other empirical research you can download the "ACT Handout" and/or check the research summaries posted on the website, which are updated more regularly.
Update in Aug 2016: a new meta-analysis is useful in many of these areas: Graham, C. D., Gouick, J., Krahé, C., & Gillanders, D. (2016). A systematic review of the use of Acceptance and Commitment Therapy (ACT) in chronic disease and long-term conditions. Clinical Psychology Review, 46, 46–58. doi:10.1016/j.cpr.2016.04.009
