Cognitive dysfunction is commonly observed among individuals with alcohol use disorder (AUD) and trauma exposure and is, in turn, associated with worse clinical outcomes. Accordingly, disruptions in cognitive functioning may be conceptualized as a trans-disease phenomenon representing a potential high-yield target for intervention. Less is known though about how different cognitive functions covary with alcohol use, craving, and post-traumatic stress symptom severity among trauma-exposed individuals with AUD. Sixty-eight male and female trauma-exposed military veterans with AUD, entering treatment trials to reduce alcohol use, completed measures assessing alcohol use and craving, post-traumatic stress symptom severity, and cognitive functioning. In multivariate models, after controlling for post-traumatic stress symptom severity, poorer learning and memory was associated with higher alcohol consumption and higher risk taking/impulsivity was associated with stronger preoccupations with alcohol and compulsions to drink. Alcohol consumption and craving, but not performance on cognitive tests, were positively associated with post-traumatic stress symptom severity. Findings suggest that interventions to strengthen cognitive functioning might be used as a preparatory step to augment treatments for AUD. Clinicians are encouraged to consider a standard assessment of cognitive functioning, in addition to post-traumatic stress symptom severity, in treatment planning and delivery for this vulnerable and high-risk population.
