Community violence and posttraumatic stress disorder symptoms in urban youth: The moderating influence of friend and parent support.

Separate lines of research have demonstrated that community violence predicts posttraumatic stress disorder (PTSD) symptoms in youth and that social support is one protective factor against the development of PTSD symptoms. The current study sought to examine the associations between primary and secondary exposure to community violence and the moderating role of parent and friend support on these relations. Participants were 96 urban youths (aged 6-17 years; 58.4% racial/ethnic minority; 51% female) and a caregiver recruited from a university mental health clinic. Results indicated that both primary and secondary exposure to community violence predicted PTSD symptoms. Friend support, but not parent support, moderated the association between primary, but not secondary, exposure to community violence and PTSD symptoms. The findings suggest that friend support is a salient protective factor for urban youth who may be at risk of PTSD symptoms due to exposure to community violence.
