Reducing Heavy Drinking Through the "Sober Curious" Movement in Australia: Protocol for a Mixed Methods Study.

BACKGROUND: Alcohol consumption is a major public health problem. Its socially engrained nature adds complexity to designing successful reduction approaches. Rather than implementing another intervention, we will undertake a natural experiment on the "sober curious" movement, which gained momentum through social media influencers promoting the idea of reducing alcohol consumption for wellness. We focus on ways to reduce alcohol consumption, through sober curiosity, with 4 heavy-drinking population groups: male construction workers; lesbian, gay, or bisexual women; hospitality workers; and tertiary education students.

OBJECTIVE: Aim 1 analyzes the sober curious movement from the "supply side" using qualitative interviews with sober curious stakeholders and a citizen science study of social media content with the 4 case study groups. We will also undertake citizen science and social media studies with a representative sample of the population. Aim 2 examines the sober curious movement from the "demand side" using qualitative interviews with the 4 case study groups to investigate their knowledge and attitudes toward sober curiosity. We will also undertake a representative national survey and ethnography with a representative sample of the population. For aim 3, we will develop evidence-based interventions leveraging sober curiosity and using citizens' juries, industry symposia, and policy symposia to develop feasible public health measures and options tailored to the needs of the 4 case study groups.

METHODS: The project involves 3 stages. Stage 1 will examine the supply side of alcohol-free products. A social media analysis of marketing by alcohol-free producers and distributors will generate an understanding of their techniques and population groups they target. In-depth interviews with producers will create evidence on the intentions behind making alcohol-free products available, their target market, and if and how they balance providing nonalcoholic products alongside alcohol. Stage 2 will be a qualitative study with 4 case study groups with high alcohol consumption: male construction workers; lesbian, gay, or bisexual women; hospitality workers; and tertiary education students. This stage will provide a deep understanding of the reasons for alcohol consumption, potential for alcohol-free product use, and possible interventions to sustainably reduce consumption. Stage 3 will involve deliberative symposia with non-alcoholic beverage producers and distributors, representatives from our case study groups, public health professionals, and policy makers to develop co-designed interventions for alcohol reduction.

RESULTS: This 3-year research protocol was funded by the Australian National Health and Medical Research Council via their Ideas Grants funding scheme (grant ID GNT2038211). The study will commence in July 2025. Human Research Ethics Committee approval has been granted.

CONCLUSIONS: Our study will provide a template for interventions designed to enable reduced drinking within heavy-drinking social worlds with huge potential for scalability of knowledge, expanding the economic, environmental, social, and cultural benefits within and across Australia and internationally.
