Participants were split into three small groups purposively chosen to ensure policy and academic and civil society representation. As a modelling team our shared belief was that alcohol use in South Africa presents a public health problem that warrants intervention, and that sufficient evidence exists to support pricing policies as a potentially cost-effective policy option. The specific objective of this exercise was to inform a problem-orientated conceptual model of the burden of alcohol in South Africa. This technique draws upon frameworks utilised within operational research for knowledge elicitation and brings together the stakeholder and researcher’s understanding of the problem in an accessible form [6 (link), 15 (link)–18 ].
A simplified map depicting causal pathways between consumption and alcohol harm in South Africa was presented and explained before each group took an A0 hardcopy to edit (Appendix 3, OSM). After 30 min the edited maps were presented back to the whole group. All changes were later merged onto one new diagram and further revisions added after email circulation post workshop.
