SweetMama: Testing of a Novel Technology for Diabetes Education and Support to Pregnant Women

Diabetes Mellitus in Pregnancy Clinical Trial

Official title: SweetMama Usability and Feasibility: Testing of a Novel Technology for Diabetes Education and Support to Pregnant Women

Status Completed

Clinical Trial Summary

Diabetes during pregnancy is a challenging clinical situation requiring substantial patient engagement. The investigators have developed a novel early-phase tool, called SweetMama, that incorporates educational, motivational and supportive elements to positively impact maternal health behaviors. This phase of work involves develop an optimized version of SweetMama via a 2-step sequential process of in-depth usability and feasibility testing. First the investigators will conduct focus groups and individual usability testing followed by refinement of SweetMama based on participant input. Next, the investigators will conduct feasibility testing via a pilot randomized trial to determine acceptability, feasibility, and pilot procedures for a fully powered larger trial.

Clinical Trial Description

In prior work, the investigators created a text messaging curriculum that was well-received by patients for diabetes-related education and support during pregnancy. The team has now drawn upon these earlier phases to develop a mobile health behavior tool to educate and support low-income, minority pregnant women with Gestational Diabetes Mellitus and Type 2 Diabetes Mellitus. This "first-of-its-kind" mHealth platform for pregnant women with GDM or T2DM is called SweetMama. SweetMama is a theory-driven application that delivers an interactive, goal-oriented educational and motivational diabetes-focused curriculum. SweetMama currently functions as a user-friendly application in which participants are delivered curriculum messages and have the opportunity to receive novel educational, motivational, or supportive content when desired by patients; they additionally have the opportunity to view library content and receive support with goal-setting.

To perform usability testing, the investigators will first conduct focus groups with 10-20 low-income pregnant women with diabetes to evaluate tool functionality, design, and interpretability. The investigators will then conduct a phase of individual usability testing with 20 women, who will use SweetMama for 2 weeks followed by qualitative (interviews) and quantitative (questionnaires and user interaction data) assessments of tool satisfaction and use.

Next, to perform feasibility testing, the investigators will recruit approximately 40 low-income pregnant women with diabetes to be randomized to either usual care or SweetMama care, from the beginning of their enrollment at this clinical site for diabetes-specific prenatal care through the first 8 weeks postpartum. Randomization will be unbalanced to favor receipt of the intervention. Participants will undergo surveys and interviews at multiple time points, and those who are randomized to experience SweetMama will undergo an exit interview. Outcomes will include retention, treatment adherence, functionality of the tool, and user interactivity with the tool. The expected outcome of the pilot RCT phase is a better understanding of feasibility of a SweetMama trial via field testing. ;
