My Diabetes Care: A Scalability and Usability Study

My Diabetes Care: A Scalability and Usability Study

The purpose of this study is to conduct a prospective, longitudinal study on the My Diabetes Care (MDC) mobile intervention to assess usage patterns, user experience, and to uncover errors in functionality prior to a larger interventional trial.

Up to 90 adult patients with type 2 diabetes mellitus will be enrolled and given access to My Diabetes Care (MDC). My Diabetes Care (MDC) is a multi-faceted patient portal intervention for mobile devices that is designed to help patients better understand their diabetes health data as well as promote and support self-management. MDC uses infographics to facilitate patients' understanding of their diabetes health data (e.g., HbA1c, LDL) and provides literacy level-appropriate and tailored diabetes selfcare information. Patients will be invited by mail to be screened for enrollment in the study. Interested patients will be able to complete an electronic consent form and enroll online via Research Electronic Data Capture (REDCap) version 5.0.8. Study participants will complete questionnaires electronically via email using REDCap at two time points: baseline (T0) and one-month follow-up (T1). Participants will complete a baseline questionnaire (T0) including basic demographic questions, items about computer usage and internet access, and validated measures of health literacy and eHealth literacy. Each participant will have access to MDC for 1 month.
