COVID-19-related intrusive thoughts and associated ritualistic behaviors.

This study evaluated COVID-19-related intrusive thoughts and associated ritualistic behaviors (CITRB). From March to May 2020, 1,118 Chinese high school students, college students, psychiatric outpatients, and community members completed a survey assessing CITRB, generalized anxiety, depression, somatization, obsessive-compulsive symptoms, and pandemic-related disruptions. Overall, participants reported mild to moderate CITRB, although certain thoughts/behaviors were more frequently endorsed, such as repeatedly telling others to take precautions against COVID-19 and checking COVID-19-related news. Being male, younger, a health-care worker, or in isolation/quarantine was associated with CITRB severity in community members. Obsessive-compulsive symptom severity, depression, somatic symptoms, and anxiety were associated with CITRB severity, although only obsessive-compulsive symptoms were uniquely associated with CITRB. This study provided evidence for the construct of CITRB, which may help mental health providers identify the nature and sources of COVID-19-related distress for some individuals as well as serve as a framework for evaluating obsessive-compulsive symptoms specific to large-scale crises.
