Purpose
This study examines differences between major city and regional and remote participants in engagement in a digital alcohol support intervention (Daybreak), risky drinking, and psychological distress and tests the mediating role of psychological distress.
Methods
This was a longitudinal, observational cohort study of Daybreak participants between January 2019 and December 2024 ( N = 12,824). Outcomes were risky drinking and psychological distress. Ordered logistic regression examined associations between the outcomes and program engagement, and multilevel generalized structural equation modeling tested mediation by psychological distress.
Findings
At 6 months, risky drinking scores declined by 42% in major city participants and 57% in regional and remote participants. High engagement in reacting to posts reduced risky drinking in both metro (OR = 0.47, 95% CI 0.27–0.80) and regional and remote areas (OR = 0.42, 95% CI 0.18–0.99). High engagement in post sharing was associated with lower odds of high risky drinking only in major city participants (OR = 0.56, 95% CI 0.33–0.98). In regional areas, participants who aimed to quit drinking at registration had lower risky drinking (OR = 0.72, 95% CI 0.53–0.99), while longer program inactivity increased odds of psychological distress (OR = 1.95, 95% CI 1.13–3.38). Psychological distress mediated 56% of the association between post reactions and risky drinking in major city participants and 33% in regional and remote participants.
Conclusions
Distinct engagement pathways across regional and remote and major city settings suggest the need for more flexible digital program designs. Psychological distress, as a partial mediator, should be both a treatment target and a mechanism of change.
