What this trial studies

This observational study utilizes the World Health Organization Composite International Diagnostic Interview-5th (CIDI-5) to evaluate the prevalence of major depressive disorders and suicidal ideation among residents in Hong Kong. To improve the accuracy of retrospective reporting, the study incorporates a life history calendar (LHC) that helps participants recall significant life events. By enhancing the CIDI-5 with the LHC, the study aims to provide a more reliable assessment of lifetime mental health issues. Participants will be randomly selected from a census list and must meet specific eligibility criteria.
