This study, examines the psychological impact of children's exposure to vio
lence and the influence of mothers' knowledge about their children's encoun
ters with violence. Our sample consists of a poor, multiethnic sample of 10
4 fourth- or fifth-grade children and their mothers. Children in this sampl
e were exposed to rather high levels of community violence, and on the whol
e, mothers greatly underestimated their children's exposure to violence and
feelings of psychological distress. Hierarchical regression analyses indic
ated that children's exposure to violence was associated with greater psych
ological distress. Our findings suggest that the detrimental effects of com
munity violence are present for all children, irrespective of their racial
background. Further, greater mother-child agreement about children's exposu
re to violence was related to better psychological functioning. The implica
tions of these results for effective parenting strategies and community-bas
ed interventions are discussed.
