The COVID-19 pandemic and obsessive–compulsive disorder in young people: Systematic review

Abstract

Background: The COVID-19 pandemic has impacted the world since the first cases were reported in China in January 2020. The secondary mental health impacts of the pandemic are thought to be significant. Obsessive–compulsive disorder is a condition defined by recurrent obsessions and compulsions. It has been hypothesised that the focus on hygiene and contamination during the pandemic could exacerbate obsessive–compulsive symptoms in young people. Method: A systematic literature review was conducted. Papers were sought looking at the effect of the pandemic on obsessive–compulsive disorder in young people. Results: Six published cross-sectional and longitudinal studies were identified, of which four studies investigated clinic samples with a diagnosis of obsessive–compulsive disorder and two looked at community adolescent populations. Five out of the six studies found that obsessive–compulsive symptoms were exacerbated during the COVID-19 pandemic. Conclusion: The COVID-19 pandemic appears to be associated with a worsening of obsessive–compulsive symptoms in young people. Being in treatment seems to have a protective effect. Maintaining mental health services during a pandemic is vital. It is important to be aware of the implications of pandemic on obsessive–compulsive symptoms in young people in order to allow them to access appropriate treatments. More research is needed in this area.
