Mental health treatment utilization among Gulf War era veterans with probable alcohol use disorder.

Introduction: Alcohol use disorder (AUD) is prevalent among veterans, and excessive alcohol use is associated with significant mental and physical health consequences. Currently, the largest cohort of veterans seeking services at the VA are those from the 1990s Gulf War Era. This cohort of veterans is unique due to the nature of their deployment resulting in a myriad of unexplained symptoms collectively known as "Gulf War Illness" and higher rates of mental health problems. The present study sought to examine the association between probable AUD and mental health treatment utilization in a sample of 1126 (882 male) Gulf War-era veterans.

Methods: Veterans completed a self-report survey including the AUDIT-C, questions about mental health treatment engagement, and demographic questions.

Results: Results demonstrated that approximately 20 % of the sample screened positive for probable AUD, determined by standard AUDIT-C cutoff scores. Among those screening positive for AUD, 25 % reported engaging in mental health treatment in the past year. Veterans with probable AUD who use VA care had 3.8 times the odds of receiving mental health services than veterans not using VA care. Use of mental health services was associated with mental health comorbidity and identifying as Black/African American.

Conclusions: The results of the present study highlight a significant unmet need for mental health treatment among Gulf War-era veterans with AUD.
