ICBT can be delivered in a self\u2010guided or clinician\u2010guided format. While a literature is emerging on the predictors of response to clinician\u2010guided ICBT, there is a lack of research examining the predictors of response to self\u2010guided ICBT. The aim of the present study was to examine predictors of outcome in a large sample of participants with OCD who commenced a self\u2010guided ICBT intervention. One hundred and fifty\u2010seven participants (<jats:italic>M<\/jats:italic><jats:sub>age<\/jats:sub>\u2009=\u200934.82; SD\u2009=\u200910.49; 78% female) were included in the study. Regression analyses were conducted to determine clinical and demographic predictors of (1) posttreatment symptom severity and (2) a clinically meaningful treatment response for both the intention\u2010to\u2010treat (ITT) and completer samples. The regression models significantly predicted posttreatment outcome for both the ITT (<jats:italic>F<\/jats:italic><jats:sub>(8,\u2009148)<\/jats:sub>\u2009=\u200915.844, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) and completer sample (<jats:italic>F<\/jats:italic><jats:sub>(8,\u2009101)<\/jats:sub>\u2009=\u20095.929, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), explaining 46% and 34% of the variance respectively. Higher baseline OCD severity, younger age, experiencing higher contamination or symmetry symptoms, and a history of past treatment were all found to be significantly associated with higher posttreatment severity in the ITT sample. In the completer sample only higher baseline OCD severity and severity of harm\u2010related obsessions and checking compulsions was significantly associated with higher posttreatment severity. When predicting treatment response the regression models for both the ITT and completer sample were nonsignificant.<\/jats:p>","DOI":"10.1002\/jclp.23710","type":"journal-article","created":{"date-parts":[[2024,6,24]],"date-time":"2024-06-24T05:29:20Z","timestamp":1719206960000},"page":"2014-2028","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Predictors of outcome in self\u2010guided internet\u2010delivered cognitive\u2010behavior therapy for obsessive\u2010compulsive disorder: A preliminary investigation"],"prefix":"10.1002","volume":"80","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9036-0699","authenticated-orcid":false,"given":"Bethany M.","family":"Wootton","sequence":"first","affiliation":[{"name":"Discipline of Clinical Psychology, Graduate School of Health University of Technology Sydney New South Wales Australia"},{"name":"School of Psychological Sciences, Faculty of Medicine, Health and Human Sciences Macquarie University North Ryde New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"McDonald","sequence":"additional","affiliation":[{"name":"Discipline of Clinical Psychology, Graduate School of Health University of Technology Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eyal","family":"Karin","sequence":"additional","affiliation":[{"name":"School of Psychological Sciences, Faculty of Medicine, Health and Human Sciences Macquarie University North Ryde New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nickolai","family":"Titov","sequence":"additional","affiliation":[{"name":"School of Psychological Sciences, Faculty of Medicine, Health and Human Sciences Macquarie University North Ryde New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blake F.","family":"Dear","sequence":"additional","affiliation":[{"name":"School of Psychological Sciences, Faculty of Medicine, Health and Human Sciences Macquarie University North Ryde New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,6,23]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0018260"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425787"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291712000244"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocrd.2014.10.003"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1037\/0033-2909.112.1.155"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.beth.2015.06.001"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjc.12365"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1037\/\/1040-3590.14.4.485"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.janxdis.2016.03.005"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1017\/bec.2014.20"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.1989.01810110048007"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/mpr.1359"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-1497.2001.016009606.x"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.2196\/jmir.9566"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.l1476"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2022.1967"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocrd.2020.100561"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2014.09.012"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/da.20694"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/wps.20299"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2022.08.037"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjc.12369"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/da.23105"},{"key":"e_1_2_10_25_1","doi-asserted-by":"publisher","DOI":"10.4306\/pi.2016.13.4.373"},{"key":"e_1_2_10_26_1","doi-asserted-by":"publisher","DOI":"10.4088\/JCP.12l07879"},{"key":"e_1_2_10_27_1","doi-asserted-by":"publisher","DOI":"10.2196\/jmir.2772"},{"key":"e_1_2_10_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/0005-7967(96)00036-8"},{"key":"e_1_2_10_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.comppsych.2015.08.007"},{"key":"e_1_2_10_30_1","volume-title":"Using multivariate statistics","author":"Tabachnick B.
