: Although post-traumatic stress disorder (PTSD) onset-persistence is thought to vary significantly by trauma type, most epidemiological surveys are incapable of assessing this because they evaluate lifetime PTSD only for traumas nominated respondents as their 'worst.'
Background Considerable research has documented that exposure to traumatic events negative effects on physical and mental health. Much less examined the predictors of event exposure. Increased understanding risk factors for could be considerable value in targeting preventive interventions anticipating service needs.
