Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Suicide is a major cause of premature death, particularly among middle-aged adults, in the majority of Western and Asian countries. A strong association of suicide and depression often indicates the necessity of a high-risk approach for suicide prevention. Improvements in identification and treatment can lead to better depression outcomes and suicide prevention. The investigators hypothesize that a 4-year community-based intervention, consisting of universal depression screening and subsequent care support in the target areas and health education programs, would result in reduced suicide rates among the middle-aged adult population in areas with a high suicide rate.

Multi-level suicide prevention programs

The study team, including staff members from the intervention municipalities, provided each municipality with a standardized form of the work plan used in our study. The intervention municipality autonomously conducted the intervention program during the implementation period.

Multi-level suicide prevention programs

Intervention Type BEHAVIORAL

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.
