Study name	Brief interventions for older adults (BIO) delivered by non‐specialist community health workers to reduce at‐risk drinking in primary care: a study protocol for a randomised controlled trial
Methods	Study design: RCT Country: Brazil
Participants	Older individuals (≥ 60 years) considered at‐risk drinkers Inclusion criteria:  a. 60 years or older; b. registered at PCUs in São José dos Campos; c. identified as at‐risk drinkers based on Alcohol Use Disorders Identification Test‐Consumption (AUDIT‐C) score ≥ 4. Exclusion criteria: a. received previous treatment for substance use disorders, except tobacco, in the last 90 days; b. severe mental or physical illness that may impair the acquisition of alcohol consumption data; c. requiring hospitalisation; d. unable to communicate clearly and/or who are intoxicated at the time of screening. Stated purpose: to address two main research questions: 1) What is the efficacy of BIO compared with usual care (waiting list) for reducing alcohol consumption in primary care? 2) What are the effects of BIO on physical activity, cognition, quality of life (QoL) and depression?
Interventions	Intervention: Brief Intervention for Older adults (BIO) The BIO is a technique with a duration 10–15 min that is designed to change behaviour and includes seven components: (1) feedback; (2) identification; (3) information; (4) reflection; (5) normative; (6) construction; (7) booklet. The intervention will be delivered by CHWs, who will receive specific training in the methodology. This BIO was based on the intervention ‘Brief Advice’ (https://www.sips.iop.kcl.ac.uk) and adapted for the older adult and the Brazilian population. The participants will receive the same usual care as the control group plus the BIO. Control: Usual care (waiting list: the participants allocated to this group will receive usual care during the period of study. For this group, we will offer the intervention immediately after the 6‐month follow‐up.)
Outcomes	Participants'outcomes of interest for this review Mental health symptoms/depression – Geriatric Depression Scale (GDS) Quality of life – Control, Autonomy, Self‐realisation and Pleasure‐16 (CASP‐16) Economic outcomes Use of health services Time points: baseline, post‐intervention (6 months)
