Trauma associated with civil conflict and posttraumatic stress disorder: evidence from the Northern Ireland study of health and stress.

The authors provide epidemiological estimates of trauma, posttraumatic stress disorder (PTSD), and associated mental disorders in Northern Ireland (NI) with a focus on the impact of civil conflict using data from the NI Study of Health and Stress (NISHS), a representative epidemiological survey of adults in NI. Overall 60.6% had a lifetime traumatic event, and 39.0% experienced a presumed conflict-related event. Men were significantly more likely to experience any traumatic event and most conflict-related event types (p < .05). The lifetime and 12-month prevalence of PTSD were 8.8% and 5.1%, respectively. Furthermore, the lifetime prevalence of any mental disorder among men and women who experienced a conflict-related trauma (46.0% and 55.9%, respectively) was significantly higher than the prevalence among men and women who did not experience this type of traumatic event (27.2% and 31.1%, respectively). Given the public health burden posed by PTSD and additional impact of conflict, specific attention must be paid to the policy, service, and clinical challenge of delivering evidence-based treatments in the wake of a tumultuous period of conflict.
