From: Do engagement and behavioural mechanisms underpin the effectiveness of the Drink Less app?
Directed acyclic graph showing potential causal mechanism for the effect of randomisation to the Drink Less app on the outcome, weekly alcohol consumption at 6-month follow-up. A series of model-based causal mediation analyses were run for each potential mediator: (1) self-reported adherence, (2) self-regulatory behaviour, (3) self-monitoring behaviour and (4) urges to drink. The unmarked blue ovals refer to ancestors of outcome, the green oval refers to exposure, and the blue oval with an ‘I’ refers to the outcome.
