The Analytical Hierarchy Process (AHP) is a multi-criteria decision-making method developed in the 1970s. It provides a structured approach to compare and prioritize different criteria based on their relative importance. AHP breaks down complex decision-making problems into a hierarchy of criteria and alternatives, allowing decision-makers to assess their impacts and make informed choices. When evaluating the impact of an HIV health education campaign, the first step is to establish the hierarchy of criteria. This hierarchy typically consists of three levels: the goal, criteria, and alternatives. The goal represents the ultimate objective, such as increasing knowledge, changing attitudes, or reducing risky behaviours. Criteria can include factors such as reach, message clarity, community engagement, and cost-effectiveness. Alternatives refer to the various strategies or interventions implemented in the campaign [1,2].
