Brief Summary

This study will evaluate a VA MyHealtheVet Secure Messaging intervention that uses different intervention messaging strategies designed to increase engagement in behaviors to prevent type 2 diabetes. The investigators will enroll 144 eligible Veterans into a 12-week MyHealtheVet Secure Messaging intervention. Eligible Veterans include those who are currently using MyHealtheVet secure messaging, meet inclusion/exclusion criteria, and have received an HbA1c test within the last 6 months that meets the ADA/CDC classification for prediabetes. Study participants will be surveyed about their engagement in behaviors to prevent TDM2 and mediators of this engagement. After completing a baseline survey, participants will be randomly assigned to receive different novel presentations of information about ways to prevent T2DM through both Secure Messaging and US Mail. The investigators will test the 5 presentations that each: (1) represent an innovative approach from behavioral economics or health psychology with great promise to increase engagement in behaviors to prevent T2DM among patients with prediabetes; and (2) have not been tested in this setting.
