Obsessive-Compulsive Disorder During the COVID-19 Pandemic Process: A Narrative Review

This study aimed to review all empirical contributions published between March 2020 and June 2022,

addressing the impact of the COVID-19 pandemic on obsessive-compulsive disorder in adults. We searched

the literature in PubMed, Google Scholar, and Web of Science. A total of 543 articles were scanned and

73 full-text articles were identified. Reviews, comments, letters to the editor, and case reports (except case

series) were excluded. It was determined that 42 articles met the inclusion criteria, 6 studies involving only

children and adolescents were excluded, and 36 were decided on their suitability for our study. The analysis

determined that COVID-19 had an impact on obsessive-compulsive disorder. Characteristics such as liability

for harm and unacceptable thoughts influenced the symptoms as well as contamination and washing. Some

studies showed an increase in the severity of obsessive-compulsive symptoms, while some reported no

worsening but improvement with treatment and follow-up. While some reported variations in outcomes

related to sociodemographic characteristics and subtypes, some focused on the risk of suicide. There were

also studies conducted on special groups such as pregnant women or healthcare workers. The results were

controversial. While available data contain more information on worsening obsessive-compulsive disorder

symptoms, data on the status of patients under treatment were scarce. There were not enough studies

evaluating follow-up results. Influencing factors such as sociodemographic characteristics, subtypes, comorbid

conditions, treatment, and support did not seem to have been adequately addressed
