About the study

The investigators will conduct a randomized controlled trial to evaluate the impact of an outreach campaign designed to increase engagement with Pack Health, a Quest Diagnostics wellness program providing individual health coaching for weight management and diabetes prevention. While employee wellness and disease-management programs have the potential to improve wellbeing and reduce healthcare costs, their effectiveness is often undermined by low engagement and selection bias in participant comparisons. This study will test whether an outreach approach that auto-enrolls eligible individuals-employees and their spouses/domestic partners-into the program, with the option to opt out, can increase engagement and improve health outcomes compared to the standard invitation-based approach.
