Summary
In collaboration with Vitality/Discovery in South Africa, an RCT amongst adult enrolled in the lowest tier of Vitality's HealthyFood benefit will be conducted. We will compare the effect of various messaging, and financial incentive strategies on healthy food purchasing behaviors in this population.
Eligibility Criteria
Inclusion Criteria
- For this study, we will focus on the following individuals:
- Adult members of Vitality Health who have activated their HealthyFood benefit in 2014 but have not completed the Vitality Age calculation or Vitality Healthy Check, and therefore are on a 10% cash- back reward level on healthy food purchases.
- Members who have chosen Woolworths as their preferred HealthyFood partner.
- Members with an available email address and SMS-capable telephone
- Members with meeting specified spending cutoff (R1000 total spend in the previous month, at least 90% of which was spent at Woolworth's.)
Exclusion Criteria
- Anyone who does not meet all of the above inclusion criteria
