Purpose: This study examined the relationship between informal social support from extended family and friends and suicidality among African Americans.
Methods: Logistic regression analysis was based on a nationally representative sample of African Americans from the National Survey of American Life (N = 3263). Subjective closeness and frequency of contact with extended family and friends and negative family interaction were examined in relation to lifetime suicide ideation and attempts.
Results: Subjective closeness to family and frequency of contact with friends were negatively associated with suicide ideation and attempts. Subjective closeness to friends and negative family interaction were positively associated with suicide ideation and attempts. Significant interactions between social support and negative interaction showed that social support buffers against the harmful effects of negative interaction on suicidality.
Conclusions: Findings are discussed in relation to the functions of positive and negative social ties in suicidality.
