New paper: Engagement & behavioural mechanisms of the Drink Less app

3 July 2024

We found that using the Drink Less app (self-reported adherence) and tracking drinking (self-monitoring behaviour) appear to be important mechanisms of action for alcohol reduction.

Full title: Do engagement and behavioural mechanisms underpin the effectiveness of the Drink Less app?

CBC researchers involved: 

This study was a process evaluation of a large UK-based randomised controlled trial evaluating the effectiveness of recommending an alcohol reduction app, Drink Less, compared with usual digital care in reducing alcohol consumption in increasing and higher risk drinkers.

The aim was to understand whether participants’ engagement (‘self-reported adherence’) and behavioural characteristics were mechanisms of action underpinning the effectiveness of Drink Less. 

Following the recommendation (self-reported adherence) and the tracking (self-monitoring behaviour) feature of the Drink Less app appear to be important mechanisms of action for alcohol reduction among increasing and higher risk drinkers.
