Rates of suicide are increasing among African American adolescents and pose a significant public health concern. One area that has received little attention is the relationship between various types of social support and suicide, and the extent to which support moderates the relationship between depressive symptoms and suicidality. A total of 212 African American adolescents completed in-school surveys on three types of social support: family support, peer support, and community connectedness. The survey also addressed depressive symptoms and suicidality, as measured by reasons for living, a cognitive measure of suicide risk. Hierarchical multiple regression analyses were used to examine direct and moderating relationships between types of social support and suicidality. The results indicated that increased family support and peer support are associated with decreased suicidality, and peer support and community connectedness moderated the relationship between depressive symptoms and suicidality. Over a third of the variability in reasons for living was predicted by family support, peer support, and community connectedness. Implications for research and preventative interventions for African American adolescents are discussed.
