Abstract
Early international evidence conducted during the COVID-19 pandemic has documented an increase in the prevalence of common mental disorder (CMD) symptoms around the globe. However, the research conducted to date is highly heterogeneous with prevalence estimates ranging dramatically across studies. The current systematic review and meta-analysis was conducted to examine the true prevalence of CMD symptoms in the adult general population during the first year of the COVID-19 pandemic (i.e., March 11, 2020-March 11, 2021). The eligibility criteria included observational studies measuring the prevalence of CMD symptoms using validated assessment tools. Newly developed COVID-19 scales and one- or two-item scales (i.e., PHQ-2, GAD-2) were excluded. Studies using only convenience or snowball sampling were also excluded. No language restrictions were implemented. Five electronic databases (ProQuest, PubMed, PsycINFO, WHO COVID Database, Web of Science) and three grey literature sources (Google Scholar, PsyArXiv, Canadian Agency for Drugs and Technologies in Health COVID resource) were searched for eligible studies on August 21, 2021. The search was updated on June 16, 2022 to identify additional studies for inclusion. Risk of bias was assessed using the quality assessment checklist for prevalence studies developed by Hoy and colleagues (2012). A total of 67 studies met inclusion criteria and were included in this review. Fifty-two studies (N = 655,310) met inclusion criteria for the meta-analysis on depression symptoms. The pooled prevalence of depression symptoms was 16.11% (95% CI = 13.89% to 18.62%; Prediction Interval [PI] = 5.00% to 43.00%). Significant moderating variables in the analysis of depression symptoms included WHO region, assessment measure, age, and COVID-19 status. Forty-eight studies (N = 543,165) met inclusion criteria for the meta-analysis on anxiety symptoms. The pooled prevalence of anxiety symptoms was 13.95% (95% CI = 12.10% to 16.02%; PI = 3.61% to 41.20%). Significant moderating variables in the analysis of anxiety symptoms included type of anxiety, WHO region, World Bank income group, assessment measure, age, COVID-19 status, COVID-19 cases, and quality assessment score. Implications of the current meta-analysis as well as suggestions for future research are explored.
