587-P: Adherence, Acceptability, and Feasibility of Mobile Ecological Momentary Assessments (mEMA) in Young Adults (YA) with Type 1 Diabetes (T1D) of Racial-Ethnic Minority Status

Abstract

Background: YA with T1D of racial-ethnic minority disproportionately experience stress related to social determinants of health (SDOH), which may be associated with hyperglycemia, glycemic variability, and poorer emotional well-being. Mobile EMA methodology uses mobile technology to assess contextually relevant, real-time behavioral and self-report data. Methods: Coupled with real-time CGM for two weeks, we employed mEMA methodology with three times daily cell phone-delivered surveys to study the association of momentary variations in SDOH-related stress with glycemia in YA with T1D from the Bronx, NY. We report our preliminary findings on acceptability, feasibility, and adherence of mEMA methodology in this ongoing study. We evaluated adherence by real-time app tracking of mEMA survey completion, and evaluated acceptability and feasibility by post-study questionnaires and qualitative interviews. Results: Thus far, 18 participants have completed the study: (mean age 23 yrs, 11 Hispanic, 7 non-Hispanic Black, mean HbA1c 8.0%). Adherence to assigned daily surveys was high at 85% (753/887 surveys). There were no differences in survey adherence across timepoints. Acceptability was high: participants reported good understanding of mEMA procedures (mean score 4/5 on Likert scale), high satisfaction (mean score 5/5), high willingness to participate again (mean score 5/5), and were very likely to recommend participation to others (mean score 5/5). For feasibility, the most common barrier cited was mEMA app issues (40%, n=7), specifically dropped survey notifications, which interfered with adherence. Conclusions: YA with T1D of racial-ethnic minority demonstrated high adherence, feasibility, and acceptability of mEMA methods, however there were app-related issues that need closer monitoring. mEMA is a viable tool to study real-time contextual and behavioral factors in minority YA with T1D.
