Building on a Point-of-purchase Intervention to Encourage Healthy Food Choices

Building on a Point-of-purchase Intervention to Encourage Healthy Food Choices

This study builds on the framework of a previously implemented color-coded food labeling intervention in a hospital cafeteria by testing the incremental effectiveness of providing employees with individual feedback and incentives for increasing healthy purchases in a 3-arm randomized controlled trial. The investigators hypothesize that employees assigned to receive feedback will increase healthy purchases more than employees who receive no contact and that employees who receive feedback plus incentives will increase healthy purchases more than those who receive feedback alone.

Inclusion Criteria:

• Employee at Massachusetts General Hospital who uses a cafeteria debit card to pay for cafeteria purchases

Exclusion Criteria:

• Employees who do not have a cafeteria debit card
• Employees with cafeteria debit card but who use it fewer than 3 times a month for the 3 months prior to start of trial
