Area of Science:

Digital health interventions
Behavioral science
Public health

Background:

Alcohol use poses significant societal health challenges.
Effective interventions for alcohol use disorder are limited.
The Daybreak program offers a digital solution for individuals seeking to modify alcohol consumption.

Purpose of the Study:

To evaluate the efficacy of the Daybreak program in reducing alcohol risk.
To compare a self-guided program with one augmented by online coaching.
To assess the impact on alcohol consumption, psychological distress, and quality of life.

Main Methods:

A randomized control trial design was employed.
Participants received either a self-guided program or one with added online coaching.
Outcomes were measured using the AUDIT-C, standard drinks per week, and quality of life surveys at 1 and 3 months.

Main Results:

Significant reductions in alcohol risk (AUDIT-C), weekly alcohol consumption, and days out of role were observed.
Quality of life improved, and psychological distress decreased.
Program engagement, not online coaching, correlated with improved outcomes.

Conclusions:

The Daybreak program demonstrates clinical effectiveness in reducing alcohol use and related harms.
The program benefits both hazardous and probably dependent drinkers.
Its scalability suggests a significant population health impact potential.
