Veterans returning from Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) have been found to be at increased risk for post-traumatic stress disorder (PTSD) and alcohol use disorders, leading to negative mental health-related quality of life (MHRQoL). The current study examined the unique impact of alcohol consumption levels versus alcohol-related consequences on the relationship between PTSD symptoms and MHRQoL in a sample of OEF/OIF combat veterans (N = 205, median age 29, 95% men). Mediation analyses indicated that the effect of PTSD symptoms on MHRQoL was explained only by alcohol-related consequences and not by alcohol consumption. Findings highlight the importance of including alcohol-related consequences in clinical assessment and intervention programs for OEF/OIF veterans. Additionally, this study enhances knowledge regarding the underlying mechanisms of functional impairment related to PTSD and alcohol use disorders.
