Objectives:: This study evaluates the effectiveness of Acceptance-Commitment Therapy (ACT) to decrease anxiety and depression in patients with opioid dependencies who are undergoing methadone maintenance treatment (MMT). Materials and Methods:: The present study was done in Mashhad from 2011-2012. Twenty-eight patients (18-50 yr) with opioid dependency who were on MMT were selected using purposive sampling and were divided equally between case and control groups. The case group received 8 sessions of individual psychotherapy with ACT. The level of depression and anxiety of these patients were measured using the Beck Depression Inventory-II and Beck Anxiety Inventory before the initiation of ACT as a pretest, 2 weeks after the termination of ACT as the posttest, and 3-months after the termination as a follow-up. The collected data was analyzed with SPSS (ver. 20) using \u03c72, paired t-test, ANOVA, and MANOVA. Results:: The pretest-posttest-follow up of anxiety showed no significant differences between the two groups (P = 0.05); however, the case group had lower depression scores in the posttest and follow-up than the control group (P = 0.04). Evaluating the results of the case group revealed that depression significantly decreased in the posttest group when compared to the pretest (P = 0.01) and there were no significant decreases in the follow up compared to the pretest (P = 0.34). Conclusion:: Short-term ACT for opioid dependent patients on MMT are not associated with a significant decrease in the level of anxiety; however, it is associated with a significant decrease in the level of depression. Nonetheless, this reduction was not maintained long term.<\/jats:p>","DOI":"10.17795\/ijpbs222","type":"journal-article","created":{"date-parts":[[2015,8,3]],"date-time":"2015-08-03T05:27:40Z","timestamp":1438579660000},"update-policy":"https:\/\/doi.org\/10.5812\/crossmark_update_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effectiveness of Acceptance-Commitment Therapy on Anxiety and Depression among Patients on Methadone Treatment: A Pilot Study"],"prefix":"10.5812","volume":"9","author":[{"given":"Mozhgan","family":"Saedy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shirin","family":"Kooshki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahmoud","family":"Jamali Firouzabadi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan","family":"Emamipour","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amir","family":"Rezaei Ardani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3819","published-online":{"date-parts":[[2015,3,20]]},"reference":[{"key":"key-idm6126144-1","first-page":"29","volume":"7","author":"Sarami\u00a0H","year":"2013","journal-title":"Quarterly J Research Addict."},{"issue":"78","key":"key-idm6101312-2","first-page":"76","volume":"20","author":"Khalatbari\u00a0J","year":"2010","journal-title":"J Guilan Univ Med Sci."},{"issue":"18","key":"key-idm2586432-3","first-page":"22","volume":"3","author":"Heidari\u00a0A","year":"2011","journal-title":"Scientific J Hamadan Univ Med Sci."},{"key":"key-idm2559152-4","author":"AliMohammadi\u00a0A","year":"","journal-title":"Comparison of Temperament-character Personality Characteristics among Addicted, Depressed, Anxious and Normal People."},{"key":"key-idm19781024-5","doi-asserted-by":"publisher","DOI":"10.1080\/09652140120070337"},{"key":"key-idm30864496-6","author":"Hayes\u00a0SC","year":"1999","journal-title":"Acceptance and commitment therapy: An experimental approach to behavior change."},{"issue":"1","key":"key-idm30843392-7","first-page":"106","volume":"6","author":"Saedy\u00a0M","year":"2012","journal-title":"Iranian J psychiatr Behavior Sci."},{"issue":"2","key":"key-idm27293040-8","first-page":"69","volume":"36","author":"Hayes\u00a0SC","year":"2003","journal-title":"Gedragstherapie."},{"issue":"4","key":"key-idm27265712-9","doi-asserted-by":"crossref","first-page":"619","DOI":"10.1901\/jaba.2007.619-632","volume":"40","author":"Twohig\u00a0MP","year":"2007","journal-title":"J Appl Behav Anal."},{"issue":"4","key":"key-idm13695040-10","doi-asserted-by":"crossref","first-page":"378","DOI":"10.1016\/S1077-7229(03)80055-X","volume":"10","author":"Heffner\u00a0M","year":"2003","journal-title":"Cogn Behav Pract."},{"key":"key-idm13660640-11","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2005.05.006"},{"issue":"1","key":"key-idm13997552-12","first-page":"17","volume":"4","author":"Talaei\u00a0A","year":"2009","journal-title":"Iranian J Psychiatr."},{"key":"key-idm13974864-13","doi-asserted-by":"publisher","DOI":"10.1002\/da.20070"},{"issue":"2","key":"key-idm30801952-14","first-page":"136","volume":"66","author":"Kaviani\u00a0H","year":"2008","journal-title":"Tehran Univ Med J."},{"key":"key-idm20545552-15","doi-asserted-by":"publisher","DOI":"10.1016\/j.beth.2010.07.002"},{"key":"key-idm20527104-16","doi-asserted-by":"publisher","DOI":"10.1037\/a0028310"},{"issue":"2","key":"key-idm20510560-17","first-page":"1","volume":"7","author":"Mojdehi\u00a0MR","year":"2011","journal-title":"J Cultural Counseling Psychotherapy."},{"issue":"1","key":"key-idm27758416-18","first-page":"117","volume":"38","author":"Vilardaga\u00a0R","year":"2007","journal-title":"Anuario de psicologia."},{"key":"key-idm27709680-19","author":"National Drug Strategy\u00a0","year":"","journal-title":""},{"issue":"2","key":"key-idm27688128-20","first-page":"466","volume":"15","author":"Rezaei Ardani\u00a0A","year":"2013","journal-title":"J Fundamentals Mental Health."},{"key":"key-idm14430160-21","doi-asserted-by":"publisher","DOI":"10.1177\/0145445507302037"},{"issue":"4","key":"key-idm13085200-22","doi-asserted-by":"crossref","first-page":"368","DOI":"10.1016\/j.cbpra.2009.06.001","volume":"16","author":"Eifert\u00a0GH","year":"2009","journal-title":"Cognitive and Behavioral Practice."},{"key":"key-idm13036752-23","author":"Taherinakhost\u00a0H","year":"2012","journal-title":"[A psycholpgical intervention manual treatment for people with stimulant use disorders.
