This article aims to provide an overview of the published studies by the International College of Obsessive-Compulsive Spectrum Disorders, in relation to the Snapshot database which has, over the past 10\u00a0years, gathered clinical naturalistic data from over 500 patients with OCD attending various research centers\/clinics worldwide. This collaborative effort has provided a multi-cultural worldwide perspective of different socio-demographic and clinical features of patients with OCD. Data on age, gender, smoking habits, age at onset, duration of illness, comorbidity, suicidal behaviors, and pharmacological treatment strategies are presented here, showing peculiar differences across countries.<\/jats:p>","DOI":"10.1017\/s1092852923002432","type":"journal-article","created":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T08:40:55Z","timestamp":1694421655000},"page":"40-48","source":"Crossref","is-referenced-by-count":4,"title":["Lessons from a multicenter, international, large sample size analysis of patients with obsessive\u2013compulsive disorders: an overview of the ICOCS Snapshot studies"],"prefix":"10.1017","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9533-8615","authenticated-orcid":false,"given":"Matteo","family":"Vismara","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0539-7150","authenticated-orcid":false,"given":"Beatrice","family":"Benatti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi A.","family":"Fineberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Hollander","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4357-5184","authenticated-orcid":false,"given":"Michael","family":"Van Ameringen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose M.","family":"Menchon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Zohar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9370-5365","authenticated-orcid":false,"given":"Bernardo","family":"Dell\u2019Osso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,9,11]]},"reference":[{"key":"S1092852923002432_r9","doi-asserted-by":"publisher","DOI":"10.1080\/13651501.2016.1207087"},{"key":"S1092852923002432_r27","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2020.07.115"},{"key":"S1092852923002432_r14","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3956(02)00087-0"},{"key":"S1092852923002432_r28","doi-asserted-by":"publisher","DOI":"10.2174\/0929867325666171222163645"},{"key":"S1092852923002432_r34","doi-asserted-by":"publisher","DOI":"10.1016\/S0193-953X(05)70176-3"},{"key":"S1092852923002432_r32","first-page":"417","article-title":"Comorbidade em trastorno obsessivo-compulsivo 3a parte: objetivos, metodologia, resultados e discuss\u00e4o","volume":"46","author":"Petrib\u00fa","year":"1997","journal-title":"J bras psiquiatr."},{"key":"S1092852923002432_r19","doi-asserted-by":"publisher","DOI":"10.1556\/JBA.1.2012.008"},{"key":"S1092852923002432_r21","volume-title":"The Anxiety Disease","author":"Sheehan","year":"1983"},{"key":"S1092852923002432_r1","doi-asserted-by":"publisher","DOI":"10.1097\/YIC.0000000000000314"},{"key":"S1092852923002432_r12","doi-asserted-by":"publisher","DOI":"10.1177\/0269881113517955"},{"key":"S1092852923002432_r24","doi-asserted-by":"publisher","DOI":"10.1016\/j.comppsych.2022.152353"},{"key":"S1092852923002432_r10","doi-asserted-by":"publisher","DOI":"10.1017\/S1092852915000565"},{"key":"S1092852923002432_r20","unstructured":"20.
