Summary

The goal of the study is to examine alcohol use behaviors of young adults through the use of testing the feasibility of adding an innovative brief personalized alcohol biomarker feedback component (TAC feedback) to an existing efficacious personalized feedback intervention, eCHECKUP TO GO (eCTG), and how (if at all) the intervention impacts drinking behaviors in high-risk college students. The study will conduct a feasibility assessment of the TAC feedback component, and will also assess the effects of the eCTG + TAC at 6-months post-baseline relative to an eCTG only group.

Conditions

• High Risk Drinking
• College Student Drinking

Interventions

Type	Name	Description
BEHAVIORAL	eCHECKUP TO GO (eCTG)	A brief, web-based program designed by San Diego State University to reduce high-risk drinking by providing personalized normative feedback regarding alcohol use, risk factors, and risks associated with drinking and accurate information about alcohol
BEHAVIORAL	eCHECKUPTOGO + brief personalized alcohol biomarker feedback intervention (eCTG + TAC)	Participants will receive the eCHECKUPTOGO in addition to the transdermal alcohol concentration (TAC) personalized feedback. The TAC is a brief individually delivered intervention based on the principles of Motivational Interviewing and focuses on increasing students' motivation to reduce harmful drinking by drinking in a safer, less risky manner. Participants will receive information on their drinking (both from the TAC sensor and daily diary data). Participants will be asked about drinking events during the past 2 weeks (how reflective they were of typical patterns and if a night stood out as particularly negative). Students will receive information and visual representations about TAC rise rates and peaks, and then be shown how their drinking during the past 2 weeks maps onto those visuals.
