Availability of family support as a moderator of exposure to community violence.

Examined the role of availability of family support in moderating the negative effects of exposure to community violence on internalizing symptoms. Participants were 75 low-income African American children between the ages of 10 and 15. Two measures of availability of family support (mother's presence in the home and family size) were evaluated as moderators of the relations between exposure to community violence and depression and posttraumatic stress disorder (PTSD) symptoms. After controlling for age, sex, and concurrent life stress, mother's presence in the home moderated the relation between exposure to community violence and depressive symptoms but not the relation between exposure to community violence and PTSD symptoms. Children living in mother-absent families were at increased risk of depressive symptoms as exposure to community violence increased. In addition, family size approached significance as a moderator of depressive symptoms but not PTSD symptoms, revealing a trend toward children from smaller families being at increased risk of depressive symptoms as exposure to community violence increased. These findings suggest that although availability of family support is an important moderator for depressive symptoms, this is not the case for PTSD symptoms.
