Randomized trial shows feedback increases drinking change intentions in Asian Americans, highlighting intervention potential.

This pilot study aims to explore how personalized feedback about ALDH2*2 and alcohol use affects drinking intentions and behaviors.
Enrolled 360 Asian American undergraduates, aged 17-25, randomized into three feedback groups: phenotype feedback only, phenotype plus genotype, and attention control.
Measured intention to change drinking and alcohol consumption over time (baseline, 1, 4, 7, and 10 months).
Participants receiving PHEN+GENE had significantly higher intention to change drinking compared to CONTROL.
Interaction between self-efficacy and threat perception significantly predicted drinking intention.
Intention to change drinking did not correlate with a reduction in heaviest week drinking quantity.

Saldich et al. (2026) studied this question.
