Interventions
The intervention included both screening and educational components. The screening component invited residents aged 36-64 years to participate in a two-step screening program. In the initial screening, a self-report questionnaire were mailed to all of those residents in the priority districts with a past high suicide rate. The second stage was conducted for the participants who screened positive though a semi-structural interview. Based on the results, participants who were diagnosed with a major depressive episode were provided with a referral to a psychiatry and support for treatment adherence. Written feedback on the screening results was mailed to all respondents. The educational component was implemented through workshops open to the general public (3 times every year) and local public newsletters (twice every year) designed to improve access and adherence to treatment and to reduce stigma associated with suicide and depression.
