For\n FM<\/jats:styled-content>\n , medical treatments alone appear insufficient. Recent meta\u2010analyses point to the utility of cognitive behaviour therapy (\n CBT<\/jats:styled-content>\n ), but effects are moderate. Within the continuous development of\n CBT<\/jats:styled-content>\n , the empirical support for acceptance and commitment therapy (\n ACT<\/jats:styled-content>\n ) has increased rapidly.\n ACT<\/jats:styled-content>\n focuses on improving functioning by increasing the patient's ability to act in accordance with personal values also in the presence of pain and distress (i.e., psychological flexibility). However, no study has yet explored the utility of\n ACT<\/jats:styled-content>\n in\n FM<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n \n To evaluate the efficacy of\n ACT<\/jats:styled-content>\n for\n FM<\/jats:styled-content>\n and the role of psychological inflexibility as a mediator of improvement.\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n In this randomized controlled trial,\n ACT<\/jats:styled-content>\n was evaluated in comparison to a waiting list control condition. Forty women diagnosed with\n FM<\/jats:styled-content>\n participated in the study. Assessments were made pre\u2010 and post\u2010treatment and at 3 months of follow\u2010up. The\n ACT<\/jats:styled-content>\n intervention consisted of 12 weekly group sessions.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Significant differences in favour of\n ACT<\/jats:styled-content>\n were seen in pain\u2010related functioning,\n FM<\/jats:styled-content>\n impact, mental health\u2010related quality of life, self\u2010efficacy, depression, anxiety and psychological inflexibility. Changes in psychological inflexibility during the course of treatment were found to mediate pre\u2010 to follow\u2010up improvements in outcome variables.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n The results correspond with previous studies on\n ACT<\/jats:styled-content>\n for chronic pain and suggest the utility of\n ACT<\/jats:styled-content>\n for\n FM<\/jats:styled-content>\n as well as the role of psychological inflexibility as a mediator of improvement.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/j.1532-2149.2012.00224.x","type":"journal-article","created":{"date-parts":[[2012,10,23]],"date-time":"2012-10-23T05:27:06Z","timestamp":1350970026000},"page":"599-611","source":"Crossref","is-referenced-by-count":204,"title":["Acceptance and commitment therapy for fibromyalgia: A randomized controlled trial"],"prefix":"10.1002","volume":"17","author":[{"given":"R.
