![]() Change in HbA 1c level was also assessed. Secondary outcomes included levels of engagement and acceptability. Primary outcome was change in carbohydrate counting ability over 3 months. Subsequently, iSpy was evaluated in a pilot randomized controlled trial with 22 iSpy users and 22 usual care controls aged 10-17 years. Errors were noted, acceptability was assessed, and refinement and retesting were performed across cycles. Participants were provided a mobile device and asked to complete tasks using iSpy app features while thinking aloud. Methods: Iterative usability testing (3 cycles) was conducted involving a total of 16 individuals aged 8.5-17.0 years with type 1 diabetes. Objective: Our objective was to test the app's usability and potential impact on carbohydrate counting accuracy. iSpy is a novel mobile app that leverages machine learning to allow food identification through images and that was designed to assist youth with type 1 diabetes in counting carbohydrates.

Outcomes will include retention, treatment adherence, functionality of the tool, and user interactivity with the tool. Participants will undergo surveys and interviews at multiple time points, and those who are randomized to experience SweetMama will undergo an exit interview. Randomization will be unbalanced to favor receipt of the intervention. 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. 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. 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. 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. SweetMama is a theory-driven application that delivers an interactive, goal-oriented educational and motivational diabetes-focused curriculum. This "first-of-its-kind" mHealth platform for pregnant women with GDM or T2DM is called SweetMama. 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. In prior work, the investigators created a text messaging curriculum that was well-received by patients for diabetes-related education and support during pregnancy. Condition or diseaseīehavioral: SweetMama Focus Groups Behavioral: SweetMama Individual Testing Behavioral: SweetMama Feasibility Testing - Pilot Randomized Trial 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. First the investigators will conduct focus groups and individual usability testing followed by refinement of SweetMama based on participant input. This phase of work involves develop an optimized version of SweetMama via a 2-step sequential process of in-depth usability and feasibility testing. The investigators have developed a novel early-phase tool, called SweetMama, that incorporates educational, motivational and supportive elements to positively impact maternal health behaviors.
