Mediating effect of readiness to change at 3 months on mean standard ethanol consumption at 12 months (n = 151).

Beta estimates (β) are unstandardised. Multiple linear regression models controlled for baseline readiness to change, AUDIT scores, and PHQ-9 scores, where the intervention was delivered (primary health centre) and who delivered it (health counsellor), and patient education. µp ≤ 0.10. *p < 0.05. ***p < 0.001. Variables as follows: β, Beta coefficient; a, a-path (CAP→mediator); b, b-path (mediator→outcome); c, direct effect (CAP→outcome); a × b, indirect effect. AUDIT, Alcohol Use Disorders Identification Test; Counselling for Alcohol Problems; PHQ-9, Patient Health Questionnaire 9.
