Abstract
War-related trauma exposure has been linked to aggression and enhanced levels of community and family violence, suggesting a cycle of violence. Reactive aggression - an aggressive reaction to a perceived threat - has been associated with posttraumatic stress disorder (PTSD). In contrast, appetitive aggression - a hedonic, intrinsically motivated form of aggression - seems to be negatively related to PTSD in offender and military populations. This study examined the associations between exposure to violence, trauma-related symptoms and aggression in a civilian population. In semistructured interviews, 290 Congolese refugees were questioned about trauma exposure, PTSD symptoms, and aggression. War-related trauma exposure correlated positively with exposure to family and community violence in the past month (r = .31, p < .001), and appetitive (r = .18, p = .002) and reactive aggression (r = .29, p < .001). The relationship between war-related trauma exposure and reactive aggressive behavior was mediated by PTSD symptoms and appetitive aggression. In a multiple sequential regression analysis, trauma exposure (β = .43, p < .001) and reactive aggression (β = .36, p < .001) were positively associated with PTSD symptoms, whereas appetitive aggression was negatively associated (β=−.13, p = .007) with PTSD symptoms. Our findings were congruent with the cycle of violence hypothesis and indicate a differential relation between distinct subtypes of aggression and PTSD.
