The Role of Functional Health Literacy in terms of Harmful Alcohol Use in Adults with Probable Posttraumatic Stress Disorder and Alcohol Use Disorder.

Purpose The current study examined functional health literacy (FHL) in regard to hazardous drinking among a sample with probable posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD). Methods Participants were 565 adults with probable PTSD and hazardous alcohol use (52.2% female, 68.8% Non-Hispanic White, average age = 39.2 years ± 10.9 years). Results FHL literacy maintained statistically significant role in terms of hazardous drinking ( p  < .001) even in the context of posttraumatic stress. Conclusion FHL may be important to better understand hazardous drinking among persons with comorbid PTSD and AUD.
