Participant Flow

All participants were recruited starting on October 13, 2021 via online platforms (e.g., craigslist) and flyers. A recruitment center was located in New Haven, Connecticut.

Out of the 33 enrolled participants, six participants did not start the study due to scheduling difficulties (N=2), no shows (N=3), and obtaining a new job (N=1).

Measure
Digital Intervention (4-week)
All participants received a 4-week digital intervention, "Emotion regulation via Breathing for Alcohol Reduction (EBA)," which combines alcohol intervention with stress reduction techniques based on self-regulated breathing exercises. The preliminary efficacy of this digital intervention was evaluated through assessments conducted before and immediately after the intervention, as well as during a follow-up assessment 30 days later.

PRIMARY outcome

Timeframe: baseline, immediately post-intervention, and follow-up (30 days)

Population: Two participants (N=2) discontinued participation in the study following the baseline assessment; One participant withdrew during the second week of the intervention due to scheduling difficulties from a personal busy schedule, and the other participant withdrew in week 4 of the intervention due to non-compliance issues (e.g., repeated instances of not showing up).
