Ecological Momentary Assessment Study of Adolescents and Young Adults With Type 1 Diabetes (EMA-T1D)

Participants will complete an in-person baseline study visit with fasting blood draw, medical and health history, anthropometrics and vital signs, and surveys. If participants are not currently using a CGM, one will be placed. The LifeData study mobile app will be installed on the participant's smartphone. Over the two-week home monitoring period, participants will be asked to wear the CGM and respond to EMA questions three times daily. After the end of the home monitoring period, a remote visit will be performed in which the CGM will be removed by the study participant at home; the study team will obtain all data available from the CGM and insulin pump (if available); and surveys will be collected.
