Global research on Obsessive Compulsive Disorder and related disorders: A scientometric assessment of global research during 2002–2021

to examine the global publication output on Obsessive Compulsive Disorder (OCD) during the last 20 years using bibliometric methods.The quantitative and qualitative analysis of global publications was performed for all the publications in Scopus database by using "OCD, Obsessive Compulsive Disorder, other related disorders" as keyword in "Title" tag.10,365 publications on OCD and related disorders were indexed in Scopus international database in the last 20 years and these publications were cited 241,962 times, averaging 23.34 citations per paper (CPP). About 24.91% share of global publication output received funding support and registered a CPP of 36.57. Among various countries, authors from USA, U.K., and Germany contributed the largest number of publications (3585, 965, and 836 publications), and publications arising from Netherlands (36.79 and 1.58), U.K. (32.65 and 1.40), and USA (32.43 and 1.39) registered the highest CPP and relative citation index (RCI). The organizations that produced the highest number of publications were Harvard Medical School, USA (487 papers), Massachusetts General Hospital, USA (454 papers), and King's College London, U.K. (297 papers). The authors who published highest number of papers were E.A. Storch (254 papers), D. Mataix-Cols (178 papers), and D.J. Stein (178 papers). The authors whose publications had highest CPP and RCI were B.D. Greenberg (USA) (73.76 and 3.16), and S.A. Rasmussen (USA) (63.36 and 2.71).This study reveals that majority of the research on OCD and related disorders is from the developed countries and compared to disorders like schizophrenia, OCD has received less research attention.
