South Korea's elderly suicide rate is not merely the highest among the member nations of the Organization for Economic Cooperation and Development, it is the highest in the world. This study analyzed the effect of ego-resilience and social support on depression and suicidal ideation of the elderly, providing baseline data to aid in the development of preventive programs on elder suicide. We found that ego-resilience is a strong inhibitor of suicidal ideation. Direct and indirect effects of social support on suicidal ideation were especially helpful for elders with mild depression.
