Currently over 3 million Veterans have adopted the VA Patient Portal, My HealtheVet (MHV), however actual use of the portal varies considerably, and the investigators have little data on how the portal features can best improve patient outcomes, or whether effective use varies by subgroups. By examining the patient portal features associated with improved outcomes and clarifying how patients can best leverage these features to better manage their diabetes, the investigators will develop and test an intervention to improve adoption and use of the patient portal for diabetes management. The goal of this small scale study, using a randomized encouragement design, is to to test the feasibility of engaging Veterans in a supported adoption intervention to promote effective MHV use, in a sample of Veterans with diabetes (with or without comorbid mental health problems).
