Associations between trauma-related guilt, symptoms of posttraumatic stress disorder, and problematic alcohol use.

Trauma-related guilt, or a belief that one should have felt, thought, or acted differently during a traumatic event in which someone's life or physical integrity was threatened, has been consistently associated with mental health disorders such as posttraumatic stress disorder (PTSD). Theories of trauma-related guilt suggest that some avoidant coping behaviors, such as problematic alcohol use, are crucial pathways connecting trauma-related guilt to PTSD but have not been thoroughly investigated. The present study uses data from a longitudinal cohort of veterans to examine two models: the first assessed problematic alcohol use as a mechanism linking trauma-related guilt and PTSD. The second explored PTSD as a mechanism linking trauma-related guilt to problematic alcohol use. Results indicated that problematic alcohol use was a significant mechanism linking global guilt and guilt cognitions with PTSD. Further, results indicated that PTSD was a significant mechanism linking global guilt and distress with problematic alcohol use. Results of our study indicate that alcohol use is a key construct that has been overlooked in the trauma-related guilt literature, despite the high prevalence of co-occurring PTSD and alcohol use (and alcohol use disorder). Targeting trauma-related guilt during integrated treatments for PTSD and alcohol use disorder may be particularly important for veterans.
