Predictors of chronic trauma-related symptoms in a community sample of New Zealand motor vehicle accident survivors.

This study examined 1,500 New Zealand community-residing adults for involvement in serious motor vehicle accident (MVA) and the development of trauma-related symptomatology. The incidence of MVA was 11 %. More than 50 % of the accident victim sub-sample reported hyperarousal, with exaggerated startle, intrusive recollections, situational avoidance, emotional reactivity, and cognitive avoidance.
