Abstract:
The present study examined the relationship between trauma exposure and smoking status and the extent to which post-traumatic stress disorder symptoms mediated this relationship in a sample of 329 college students who experienced a prior traumatic event. Participants experienced an average of 2.2 prior traumas, and approximately 15% (n = 49) were smokers. Bootstrapping analyses revealed that after controlling for age, gender and time since trauma, post-traumatic stress disorder symptoms served as a pathway through which trauma exposure increased the risk of smoking [BC 95% CI (0.02, 0.18)]. Results appeared to be due largely to the influence of hyperarousal symptoms [BC 95% CI (0.05, 0.22)]. Comprehensive interventions for undergraduate smokers may be improved by attending to the impact of prior trauma and mental health needs.
