There has been limited research investigating if comorbid sleep difficulties impair treatment outcome for OCD and if the sleep difficulties change following OCD\u2010treatment. Thirty\u2010six patients with obsessive compulsive disorder underwent concentrated exposure treatment delivered in a group over four consecutive days and were assessed with measures of OCD, depressive symptoms and sleep disturbance at three different time points (pre, post and 6 months follow\u2010up). The sample was characterized by a high degree of comorbidity with other psychiatric disorders. At pre\u2010treatment nearly 70% of the patients reported sleep difficulties indicative of primary insomnia. The results showed that patients had large reductions of OCD\u2010symptoms as well as significant improvements in sleep disturbance assessed after treatment, and that these improvements were maintained at follow\u2010up. Sleep disturbance did not impair treatment outcome, on the contrary patients with higher degree of sleep disturbance at pre\u2010treatment had better outcome on OCD\u2010symptoms after treatment. The results indicated that the majority of the OCD sample suffered from sleep disturbances and that these sleep disturbances were significantly reduced following adequate treatment of OCD without specific sleep interventions. However, a proportion of the patients suffered from residual symptoms of insomnia after treatment.<\/jats:p>","DOI":"10.1111\/sjop.12417","type":"journal-article","created":{"date-parts":[[2017,12,16]],"date-time":"2017-12-16T16:46:33Z","timestamp":1513442793000},"page":"186-191","source":"Crossref","is-referenced-by-count":20,"title":["Sleep disturbances in treatment\u2010seeking OCD\u2010patients: Changes after concentrated exposure treatment"],"prefix":"10.1111","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6066-1164","authenticated-orcid":false,"given":"H\u00e5kon","family":"Nordahl","sequence":"first","affiliation":[{"name":"Haukeland University Hospital OCD\u2010team Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audun","family":"Havnen","sequence":"additional","affiliation":[{"name":"Haukeland University Hospital OCD\u2010team Bergen Norway"},{"name":"Department of Clinical Psychology University of Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bjarne","family":"Hansen","sequence":"additional","affiliation":[{"name":"Haukeland University Hospital OCD\u2010team Bergen Norway"},{"name":"Department of Clinical Psychology University of Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars\u2010G\u00f6ran","family":"\u00d6st","sequence":"additional","affiliation":[{"name":"Haukeland University Hospital OCD\u2010team Bergen Norway"},{"name":"Department of Psychology Stockholm University Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerd","family":"Kvale","sequence":"additional","affiliation":[{"name":"Haukeland University Hospital OCD\u2010team Bergen Norway"},{"name":"Department of Clinical Psychology University of Bergen Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,12,15]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890423349"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/1097-4679(198411)40:6<1365::AID-JCLP2270400615>3.0.CO;2-D"},{"key":"e_1_2_7_5_1","volume-title":"Beck Anxiety Inventory manual","author":"Beck A.
