Abstract Evidence demonstrating the association of preexisting psychiatric disorders with post-COVID-19 is limited. We aim to investigate the association using larger sample sizes and more extended postinfection periods than previous studies. A total of 6015 (response rate = 77.5%) COVID-19 survivors were surveyed using a self-administered questionnaire from July to September 2021. Poisson regression analysis with robust error variance was performed to estimate post-COVID-19 prevalence ratios (PRs) with or without preexisting psychiatric disorders. Participants with preexisting psychiatric disorders numbered 1067 (17.7%), and with post-COVID-19 were 2149 (35.7%). Post-COVID-19 PR with preexisting psychiatric disorders was 1.09 (95% CI 1.02–1.18, p = 0.013). The interaction between preexisting psychiatric disorders and postinfection periods was significant (p for interaction < 0.001). The subgroup analysis showed that those with preexisting psychiatric disorders might be at greater prolonged risk of post-COVID-19 than those without the disorders. These findings suggested that preexisting psychiatric disorders were associated with an increased post-COVID-19 risk, and post-COVID-19 with preexisting psychiatric disorders might prolong even if time passes.
