This project involves development and preliminary evaluation of a patient-centered education and self-care tool for use with women whose pregnancies are complicated by diabetes. The study begins with development of a text messaging curriculum to provide motivational and educational support. We will use a one-way, non-interactive text-based educational platform to provide supportive and educational messages to a cohort of 40 women with diabetes. Women receive 3-5 text messages per week until delivery. The goal is to develop a program that can be expanded to a clinical trial in which perinatal outcomes are assessed.
