The study included 48 adolescents aged 12\u201318 years with OCD, 35 unaffected siblings, and 39 healthy controls. Participants completed an antisaccade task using an eye-tracking device. Antisaccade correct response rate and latency were evaluated as the primary outcomes, whereas saccadic velocity was examined as an exploratory measure of oculomotor execution. The OCD group showed lower antisaccade correct response rate and longer latency compared with healthy controls, whereas the sibling group demonstrated intermediate performance. Exploratory analyses identified statistically significant group differences in mean saccadic velocity; however, this finding should be interpreted cautiously. Regression analyses indicated that both OCD diagnosis and sibling status were independently associated with antisaccade correct response rate and latency, whereas findings for saccadic velocity should be considered exploratory. These findings suggest that impairments in antisaccade performance may not be specific to OCD but may also be present, albeit to a milder extent, in unaffected siblings, providing preliminary evidence supporting antisaccade performance as a candidate familial-risk marker for OCD that warrants further investigation within an endophenotype framework.<\/jats:p>","DOI":"10.3390\/jemr19040078","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T07:29:39Z","timestamp":1784100579000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Antisaccade Performance in Adolescent Obsessive\u2013Compulsive Disorder: Evidence from a Familial-Risk Design"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6623-7375","authenticated-orcid":false,"given":"Oguz Bilal","family":"Karakus","sequence":"first","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Trabzon Kanuni Training and Research Hospital, Trabzon 61290, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayse","family":"Akca","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Trabzon Kanuni Training and Research Hospital, Trabzon 61290, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammed Said","family":"Demirkan","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Trabzon Kanuni Training and Research Hospital, Trabzon 61290, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-1600-2857","authenticated-orcid":false,"given":"Zeynep Ahsen","family":"Ozcan","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Trabzon Kanuni Training and Research Hospital, Trabzon 61290, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0531-5215","authenticated-orcid":false,"given":"Didem","family":"Cek Ozturk","sequence":"additional","affiliation":[{"name":"BEH Children and Young People Mental Health Services, North London NHS Foundation Trust, Edgware Community Hospital, Burnt Oak Broadway, Edgware HA8 0AD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9340-499X","authenticated-orcid":false,"given":"Ilayda","family":"Barankoglu Sevin","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Dr. Behcet Uz Training and Research Hospital, Izmir 35210, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7612-2601","authenticated-orcid":false,"given":"Sumeyra","family":"Karakus","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases and Clinical Microbiology, Trabzon Kanuni Training and Research Hospital, Trabzon 61290, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim Selcuk","family":"Esin","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Trabzon Kanuni Training and Research Hospital, Trabzon 61290, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2990-9851","authenticated-orcid":false,"given":"Onur Burak","family":"Dursun","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Trabzon Kanuni Training and Research Hospital, Trabzon 61290, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"53","DOI":"10.1038\/mp.2008.94","article-title":"The epidemiology of obsessive-compulsive disorder in the National Comorbidity Survey Replication","volume":"15","author":"Ruscio","year":"2010","journal-title":"Mol.
