title: An examination of alcohol risk profiles and co-occurring mental health symptoms among OEF/OIF veterans.
abstract: Compared to the general population, veterans of the wars in Afghanistan and Iraq (OEF/OIF) are more likely to engage in hazardous alcohol use and meet criteria for mental health disorders including Posttraumatic Stress Disorder (PTSD) and Major Depressive Disorder. Less is known how distinct profiles of alcohol use behavior relate to mental health symptoms.
  
  
  
  The current study examined the extent that indicators of alcohol use (i.e., drinks per week, peak blood alcohol concentration, and alcohol-related problems) are categorized into different alcohol risk profiles utilizing a person-centered approach. We also examined how mental health symptoms (i.e., PTSD, depression, and anxiety-related symptoms) were associated with the alcohol risk profiles. Participants were 252 Veterans who reported consuming alcohol within the past month.
  
  
  
  Latent profile analysis indicated a four-class solution yielded the best-fitting model, and profiles were named based on their respective levels and patterns of alcohol use. Mental health symptoms were significantly different among the four profiles. Profiles of veterans who endorsed more alcohol-related problems (i.e., the "Severe alcohol behavior" and "Steady drinkers with functional impairment") also reported comorbid clinical symptoms of PTSD, depression, and anxiety. The "Binge drinkers with no functional impairment" and "Mild alcohol behavior" profiles reported the lowest levels of mental health symptoms.
  
  
  
  Findings highlight the unique relationship between distinct alcohol risk profiles and mental health outcomes. Targeted interventions and treatment options based on unique alcohol risk profiles may be helpful in tailoring prevention and intervention efforts in detecting co-occurring mental health symptoms among OEF/OIF veterans.
