Dynamic Tracking to Identify Topics and Thematic Evolution of Obsessive-compulsive disorder as an Emerging Topic

Abstract

This study aims to draw a science map, provide structural analysis, explore the evolution, and determine new trends in research articles published in the field of obsessive-compulsive disorder (OCD). The articles published from 1981 to 2021 were retrieved by searching the related keywords in multiple databases including PubMed, Scopus, and Web of Science, according to their thematic coverage and scope. The papers were analyzed using R and SciMAT software. A total of 1820 articles were analyzed and 4191 keywords plus, and 3242 author keywords were reported in the journals. Moreover, 7482 authors contributed in conducting these studies, of which 111 articles were written by single authors, and the collaborative coefficient was 4.36. Neuropsychopharmacology, International Clinical Psychopharmacology, and Journal of Clinical Psychopharmacology are the most significant journals publishing OCD articles. This study uncovered new insights into the evolution trend of the leading research stream on OCD over the past years. The findings of this study can contribute to developing the OCD Global Research Program and policymakers.
