A Randomized Trial of a Personalized Feedback Intervention for Nonstudent Emerging Adult At-Risk Drinkers

Emerging adulthood is a period of heightened vulnerability for problematic alcohol use. Considerable research has been devoted to reducing alcohol risks in college student populations, although far less effort has focused on their noncollege-attending peers. Research targeting nonstudent emerging adults is critical as this group is at risk of experiencing alcohol-related harms. Consequently, the main objective of the present randomized study was to examine the preliminary efficacy of a brief personalized feedback intervention (PFI) tailored for nonstudent at-risk drinkers. We also examined the influence of gender on intervention outcomes. Finally, we explored participant acceptability of the intervention.

Participants were 164 (65.9% men) emerging adults (M age = 21.98, SD = 2.02) recruited from the community. They were randomly assigned to either a 50-minute, in-person PFI or an assessment-only control group and were assessed over 9 months postintervention.

Results showed that for short-term change (1 month), the PFI condition reduced drinking significantly more than controls. For longer-term change (1 to 9 months), both conditions continued to show gradual decline in consumption. The groups did not differ in alcohol-related problems, and the intervention was equally effective for both women and men. Regarding acceptability, participants were extremely satisfied with the intervention, perceived the information to be personally relevant, and thought it provided them a new way of looking at their own drinking.

Overall, the present research advanced knowledge regarding an understudied and at-risk group of drinkers. This is among one of the first randomized studies to evaluate a brief intervention tailored to the needs of nonstudent emerging adults based on prior formative research with this group. Our data support PFI as a promising intervention approach for nonstudent drinkers in the community. Ultimately, this line of research aims to reduce alcohol-related health disparities associated with inequities in education.
