A prospective examination of the relationships between PTSD, exposure to assaultive violence, and cigarette smoking among a national sample of adolescents.

Research demonstrates robust associations among posttraumatic stress disorder (PTSD), exposure to assaultive violence (i.e., sexual assault, physical assault, and witnessed violence), and cigarette smoking among adults and adolescents. Whether exposure to assaultive violence confers risk for cigarette smoking over and above the effects of PTSD and non-assaultive traumatic events (e.g., motor vehicle accidents) is unclear. The current study prospectively measured PTSD, assaultive violence exposure, non-assaultive traumatic event exposure, and cigarette smoking three times over approximately three years among a nationally representative sample of adolescents (N=3614, age range 12-17 at Wave 1). Results revealed that multiple exposure to assaultive violence at Wave 1 was a consistent and robust prospective predictor of cigarette smoking at Waves 2 and 3. By contrast, PTSD diagnoses and non-assaultive traumatic event exposures at Wave 1 only predicted cigarette smoking at Wave 2, but not at Wave 3. Theoretical and clinical implications are discussed.
