Sustainable effects on suicidality were found for the Nuremberg alliance against depression

Area of Science:

• Public Health
• Epidemiology
• Mental Health Interventions

Background:

• Suicidality poses a significant public health challenge.
• Effective community-based interventions are crucial for suicide prevention.
• Assessing the long-term sustainability of interventions is vital.

Purpose of the Study:

• To evaluate the sustainability of a community-based intervention's effects on suicidality.
• To compare the reduction in suicidal acts in an intervention region versus a control region post-intervention.

Main Methods:

• A four-level community-based intervention program (Nuremberg Alliance Against Depression - NAD) was implemented in Nuremberg from 2001-2002.
• Suicidal acts (completed and attempted suicides) were monitored in Nuremberg and a control region (Wuerzburg).
• Data from the intervention years (2001-2002) and a follow-up year (2003) were compared to baseline (2000) and the control region.

Main Results:

• The intervention resulted in a significant -21.7% reduction in suicidal acts during 2001-2002 compared to baseline and the control region.
• In the follow-up year (2003), the reduction in suicidal acts in Nuremberg was -32.4% compared to baseline, significantly greater than in the control region (P = 0.0065).
• The reduction in suicidal acts in the follow-up year was numerically larger than during the intervention years, indicating sustained effects.

Conclusions:

• The Nuremberg Alliance Against Depression (NAD) intervention demonstrates sustainable preventive effects on suicidality one year after its termination.
• The four-level intervention model appears to be a cost-effective approach to suicide prevention.
• The NAD intervention's success supports its broader implementation in other regions.
