Biomarkers for Alcohol Measurement
BHI researchers are leading the world in the use of alcohol biomarkers to assess alcohol use. Funded by the National Institute on Alcohol Abuse and Alcoholism, our team focuses on using alcohol biomarkers like ethyl glucuronide (EtG), a urine test that can detect drinking for 2-5 days. EtG allows us to accurately and feasibly conduct contingency management interventions for alcohol use disorders. Having conducted thousands of EtG tests, our group has published about best practices use of EtG in research and clinical settings. BHI faculty are also conducting research on the biomarker phosphatidylethonal (PEth), which can detect use for up to 28 days, as well as bluetooth enabled brethalyzers. We are using all these biomarkers to improve assessment of alcohol outcomes and personalize treatments for individuals with alcohol use disorders.

Re-Centering Measures for Alcohol Misuse Among American Indian and Alaska Native Communities
The 50-item self-report survey the Drinker Inventory of Consequences (DrInC) and its’ shorter 15-item, companion, the Short Inventory of Problems (SIP) assess five domains related to drinking consequences: (1) physical, (2) intrapersonal, (3) social responsibility, (4) interpersonal and (5) impulse control. Along with our Tribal partners, we are culturally adapting the existing measures. A Community Advisory Board (CAB) has been convened with AI/AN leaders and content experts to assess the existing DrInC/SIP measure(s) for item content validity and to make recommendations for additional items to capture culturally relevant negative consequences associated with alcohol misuse. The adapted measure will then be available online for AI/AN adults to complete.
