Social support and depression among elderly Korean immigrants in the United States.

Based on the integrative concept of social support, we investigated the effects of quantitative, structural, and functional aspects of social relationships on the level of depressive symptoms among elderly Korean immigrants, taking into account their level of acculturation and life stress. Korean elders having more close persons and more frequent contacts with them exhibited fewer depressive symptoms. Networks providing instrumental support consisted mainly of family ties; networks for emotional support included diverse relationships as well as family members. Emotional support was found to moderate the harmful effect of life stress, and thus to be more relevant than instrumental support to the mental health of Korean elderly.
