ACT studies Based on Computers, Phones, SmartPhones, and Books

Lappalainen, P., Granlund, A., Siltanen, S., Ahonen, S., Vitikainen, M., Tolvanen, A., & Lappalainen, R. (2014). ACT Internet-based vs face-to-face? A randomized controlled trial of two ways to deliver Acceptance and Commitment Therapy for depressive symptoms: An 18-month follow-up. Behaviour Research and Therapy, 61, 43-54. DOI: 10.1016/j.brat.2014.07.006 RCT comparing face to face with internet based ACT for outpatients experiencing mild or worse depression. 6 weekly therapy sessions versus 6 weeks of access to an ACT-based Internet program.

Muto, T., Hayes, S. C., & Jeffcoat, T. (2011). The effectiveness of Acceptance and Commitment Therapy bibliotherapy for enhancing the psychological health of Japanese college students living abroad. Behavior Therapy, 42, 323–335. RCT on the impact of Get Out of Your Mind and Into Your Life on the mental health of international students (N = 70). Better general mental health at post and follow up. Moderately and above depressed or stressed, and severely anxious students showed improvement compared to those not receiving the book. Outcomes mediated and moderated by psychological flexibility.

Jeffcoat, T. & Hayes, S. C. (2012). A randomized trial of ACT bibliotherapy on the mental health of K-12 teachers and staff. Behaviour Research and Therapy, 50, 571-579. ACT RCT with K – 12 school personnel (N = 236; 91% female; 30 - 60 years old) in a wellness program compared to wait list. Three-fourths were above clinical cutoffs in general mental health, depression, anxiety, or stress. Participants read the book for two months, completed exercises and quizzes, and after post assessment were followed for 10 weeks; wait list participants were then also given the book with two months to complete it. Overall, participants showed significant improvement in psychological health. Significant preventive effects for depression and anxiety were observed along with significant ameliorative effects for those in the clinical ranges of depression, anxiety and stress. Follow up general mental health, depression, and anxiety outcomes were related to the manner in which participants used the workbook and to post levels of psychological flexibility.

Smoking cessation was mediated by increases in total acceptance of physical, cognitive, and emotional cues to smoke (80% of the effect).
