Hazardous alcohol use and treatment outcome in male combat veterans with posttraumatic stress disorder

Abstract

The relationship between alcohol problems and posttraumatic stress disorder (PTSD) remains unclear. Six hundred and eight combat veterans diagnosed with PTSD were assessed for PTSD symptoms and alcohol problems prior to group cognitive-behavioral treatment. They were reassessed 3 and 9 months after treatment. Participants were classified into low-risk and hazardous drinkers at each time point. Drinking status at intake did not predict PTSD symptoms at intake or follow-up. However, drinking status was associated with PTSD symptoms when both were assessed at follow-up. PTSD arousal symptoms were the only symptom cluster to differentiate drinking groups.
