Study Summary

The purpose of this study is to conduct a two-arm, parallel-design, pragmatic randomized controlled trial of a patient portal intervention for diabetes, My Diabetes Care, to evaluate its effect on patient activation and secondary cognitive, behavioral, and clinical outcomes.

Each item uses a 4-point Likert-type scale of response options ranging from strongly disagree to strongly agree. PAM-13 item responses result in total raw scores ranging from 13 to 52, which we converted to the linear interval scale of patient activation scores, ranging from 0 (lowest act
