A growing body of empirical evidence suggests that both parents and peers have unique and interactive effects on youth psychosocial adjustment; however, the generalizability of these findings to low-income, African American youth is questionable. This study aimed to replicate and extend this research by examining the relative contribution of parents and peers to internalizing and externalizing problems among 277 low-income, African American youth (7 - 15 years). Results demonstrated that both parenting and peer relations contributed to youth psychosocial adjustment, although the specific nature of the findings depended on the assessment and outcome examined. Clinical implications and directions for future research are discussed
