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.
