The National Institutes of Health (NIH), through the National Institute on Alcohol Abuse and Alcoholism (NIAAA), is inviting applications for the Alcohol Health Services Research (R01 Clinical Trial Optional) grant. This funding opportunity aims to address the treatment gap for individuals with Alcohol Use Disorder (AUD) by focusing on five key areas: increasing treatment accessibility, enhancing the appeal of treatments, analyzing cost structures and insurance systems, researching the dissemination of evidence-based treatment approaches, and minimizing health disparities among affected populations. The initiative is crucial for advancing research that improves outcomes for individuals struggling with AUD, with grants available for a project period of up to five years and a direct cost limit of $500,000. Interested applicants can find more information and submit proposals by the closing date of September 7, 2026, and may contact NIH Grants Information at grantsinfo@nih.gov for further inquiries.
