Abstract: The megastudy is a promising concept for testing and evaluating behavioural interventions. As a scaled up RCT, it allows an apples-to-apples comparison of a battery of interventions applied to the same sample. But the devil is in the details: the megastudy is useful insofar as the interventions are designed and selected appropriately. This talk will discuss a stakeholder-informed, crowd-sourcing approach to intervention development. As a case study, it will frame the discussion around an ongoing project: The AMR Intervention Development and Forecasting Collaboration, a stakeholder-informed megastudy of behavioural interventions designed to improve behaviours that reduce the spread of antimicrobial resistance (AMR).
