Post-9/11 veterans are at increased risk for developing PTSD and alcohol misuse. Many studies have examined the relationship between PTSD, alcohol misuse, and functional impairment and a few studies have examined the context in which drinking takes place. However, research has yet to examine solitary drinking in the context of PTSD. Using prospective data, the study tested the following hypotheses in a sample of post-9/11 veterans with PTSD via regression analyses: greater severity of PTSD would predict more time spent drinking alone (as a proportion of all drinking occasions), as would greater alcohol use and alcohol-related consequences, and a higher proportion of solitary drinking would predict worse functional impairment. It was also hypothesized that solitary drinking would predict future alcohol-related consequences. The hypotheses were not supported. The findings suggest that the more veterans with PTSD drink alcohol, they are likely to experience greater alcohol-related consequences, regardless of drinking in a solitary or social setting.
