Federal Project Grant Award Summary

The University of Pittsburgh received a $700,134 Project Grant from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) under the Alcohol Research Programs (CFDA 93.273), awarded June 15, 2026, with completion targeted for February 28, 2031. This research project delivers translational scientific investigation examining the development of alcohol tolerance among young adults and its relationship to problematic alcohol use (PAU). The study will recruit 300 low-risk drinking 18-19 year-olds and employ repeated assessment methodologies to track tolerance trajectories across four distinct alcohol effects—stimulation, sedation, tension-reduction, and hangover—over the five-year performance period. Data collection will combine periodic survey measures administered every six months with ecological momentary assessment bursts conducted annually, while statistical modeling will control for situational covariates including alcohol consumption patterns and substance use to isolate innate differences in alcohol adaptation.

The research addresses a significant gap in human translational research regarding whether faster-developing alcohol tolerance constitutes a neurobiological risk factor for problematic alcohol use, a phenomenon well-established in preclinical work but understudied in human populations. By examining whether tolerance to different alcohol effects develops at varying rates and determining which tolerance patterns predict PAU, this project will generate evidence to inform prevention and intervention strategies for alcohol-related problems. The deliverables will contribute fundamental knowledge applicable to the NIAAA's mission of developing improved treatment methods and prevention strategies for alcoholism and alcohol-related disorders.
