57. Association of trauma and aggressive behavior in an early psychosis population.
Individuals with psychosis are at greater risk for aggressive behavior (AB) than the non-psychiatric population. Prior research indicates strong links between trauma exposure and risk for AB, but few studies have examined this relationship in early psychosis (EP) populations. AB and trauma history were coded retrospectively using clinician administered questionnaires, and self-report measures for 427 individuals with first-episode psychosis (FEP; 72% male, 16% Hispanic, ages 12-35 M=20.09±4.12). We measured AB towards others, self, and objects using a 10-point severity scale based on the Modified Overt Aggression Scale. We hypothesized that participants with at least one type of trauma will report higher prevalence and severity of AB than those with no history of trauma. FEP individuals with a trauma history (19%) report higher rates of AB (p<0.001) and greater severity of AB (p<0.001). Individuals with a trauma history are more likely to engage in AB towards others and objects, but not self, than those with no trauma history (p<0.001). Results suggest that experience of trauma is associated with more severe and greater likelihood of AB in FEP. This indicates trauma screening is an important element of risk-management in EP individuals and targeted trauma treatment may lead to reductions in AB.
