Testing the Effectiveness of Different Messaging Approaches to Increase Doctor Visits Amongst Individuals With Risk Factors for Diabetes

The purpose of the research is to test the effectiveness of different messaging approaches to nudge members of Vitality and Discovery Health, with risk factors for diabetes (based on data from the Vitality Health Check and Vitality Age assessment), to visit a doctor and test for diabetes. The messages are based on concepts from behavioural economics that aim to make information on screening more salient by using the concept of social proof (person like you) and an authoritative source (a diabetes specialist and the Vitality doctor).
