Likewise, subthreshold psychosis symptoms (clinical high risk for psychosis; CHR) and obsessive compulsive symptoms (OCS) often overlap and may be difficult to differentiate. This study aimed to replicate research investigating the prevalence of OCD in a CHR clinic sample, validate and investigate factor structure of a self\u2010report OCS measure in a CHR sample, explore how OCS may relate to CHR and co\u2010occurring symptoms, and investigate whether real\u2010world CHR treatment improves OCS and CHR symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>This study analysed archival clinical data from baseline and 6\u2010month follow\u2010up assessments collected by a specialist outpatient CHR clinic. Data included assessments of CHR symptoms, OCS, and clinician\u2010rated diagnosis. Exploratory factor analysis examined the OCS measure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Within this CHR clinic sample, 13.5% experienced co\u2010morbid OCD. The self\u2010report OCS measure had two factors: (1) checking and counting behaviours and (2) intrusive thoughts and images of harm\/guilt. The checking and counting factor correlated with depression and social anxiety. The intrusive thoughts and images of harm\/guilt factor significantly correlated with unusual thought content and social anxiety. Between baseline to 6\u2010month follow\u2010up, clients exhibited CHR symptom improvement regardless of OCD diagnosis. However, OCS did not change.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These findings support validity of a self\u2010report OCS measure in a CHR clinic sample and that types of OCS experiences may exhibit different clinical patterns. Additionally, it appears that individuals with comorbid OCD responded similarly to CHR treatment compared to those without OCD.<\/jats:p><\/jats:sec>","DOI":"10.1111\/eip.13596","type":"journal-article","created":{"date-parts":[[2024,7,24]],"date-time":"2024-07-24T05:12:05Z","timestamp":1721797925000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Overlap of obsessive compulsive and psychosis risk symptoms in a specialized clinic"],"prefix":"10.1111","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1080-8452","authenticated-orcid":false,"given":"Michelle L.","family":"West","sequence":"first","affiliation":[{"name":"Department of Psychiatry University of Colorado School of Medicine, Anschutz Medical Campus  Aurora Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8671-3631","authenticated-orcid":false,"given":"James","family":"Green","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Beth Israel Deaconess Medical Center  Boston Massachusetts USA"},{"name":"Department of Mental Health Massachusetts Mental Health Center  Boston Massachusetts USA"},{"name":"Brookline Center for Community Mental Health  Brookline Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Madison E.","family":"Barber","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of Colorado School of Medicine, Anschutz Medical Campus  Aurora Colorado USA"},{"name":"Metropolitan State University of Denver  Denver Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1554-0966","authenticated-orcid":false,"given":"Shadi","family":"Sharif","sequence":"additional","affiliation":[{"name":"Department of Psychiatry University of Colorado School of Medicine, Anschutz Medical Campus  Aurora Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victoria","family":"Lisowski","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Beth Israel Deaconess Medical Center  Boston Massachusetts USA"},{"name":"Department of Mental Health Massachusetts Mental Health Center  Boston Massachusetts USA"},{"name":"Brookline Center for Community Mental Health  Brookline Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michelle","family":"Friedman\u2010Yakoobian","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Beth Israel Deaconess Medical Center  Boston Massachusetts USA"},{"name":"Department of Mental Health Massachusetts Mental Health Center  Boston Massachusetts USA"},{"name":"Brookline Center for Community Mental Health  Brookline Massachusetts USA"},{"name":"Department of Psychiatry Harvard Medical School  Boston Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,7,23]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/HRP.0000000000000027"},{"key":"e_1_2_8_3_1","volume-title":"Global functioning: Social scale (GF: Social)","author":"Auther A.
