Objective: Few studies have examined the contribution of specific disaster-related experiences to symptoms of depression. The aims of this study were to do this by examining the roles of peri-traumatic stress and distress due to lingering disaster-related disruption in explaining linkages between disaster exposure and major depressive disorder symptoms among a cohort exposed to the 2010-2011 Canterbury (New Zealand) earthquakes. Methods: Structural equation models were fitted to data obtained from the Christchurch Health and Development Study at age 35 (n = 495), 20-24 months following the onset of the disaster. Measures included earthquake exposure, peri-traumatic stress, disruption distress and symptoms of major depressive disorder. Results: The associations between earthquake exposure and major depression were explained largely by the experience of peri-traumatic stress during the earthquakes (? = 0.180, p < 0.01) and not by disruption distress following the earthquakes (? = 0.048, p = 0.47). Conclusion: The results suggest that peri-traumatic stress has been under-recognised as a predictor of major depressive disorder.
