Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The investigators will work with one of Vitality's partner corporations to test whether curiosity can motivate employees to follow through on their virtuous intentions and complete their annual health risk assessment (VHR). Employees will receive email messages that contain either a curiosity-inducing question or a standard encouragement message. The investigators predict that presenting people with curiosity-arousing questions will make them more likely to complete a health risk assessment, as compared to standard messages.
