The study will also examine whether this type of monitoring is practical and acceptable for participants and clinicians. The main questions it aims to answer are:\n\n* Can researchers successfully collect wearable and survey data throughout late pregnancy and the first 3 months after birth?\n* Do participants and clinicians find wearable-based monitoring easy to use and helpful?\n* Are changes in sleep, heart rate, activity, and other wearable data linked to mood changes during the perinatal period?\n\nResearchers will compare 2 wearable devices, the Oura Ring and EmbracePlus, to see which device provides more complete and usable data.\n\nParticipants will:\n\n* Wear either the Oura Ring or EmbracePlus device every day from the third trimester of pregnancy until 3 months after birth\n* Complete short daily and biweekly questionnaires about mood and wellbeing\n* Allow the wearable device to collect information such as sleep, heart rate, heart rate variability, and physical activity\n\nThe study will include 10 participants. Researchers will measure feasibility by looking at how many participants join the study and how much study data is completed. The study team hopes at least 70% of scheduled study activities data will be collected.\n\nResearchers will also interview 5 participants and 4 reproductive psychiatry clinicians about their experiences using wearable monitoring. These interviews will explore ease of use, usefulness in clinical care, and how wearable data may fit into electronic medical records.\n\nThis study may help researchers develop future tools that can predict the risk of perinatal depression earlier and support more personalized care during pregnancy and after birth.",[152],"Perinatal Depression",[154,155,156,157,158,159,160,161,162,163,164,165,152],"Pregnancy","Ecological Momentary Assessment","Monitoring, Ambulatory","Depression, Postpartum","Wearable Electronic Devices","Heart Rate","Risk Assessment","Patient Acceptance of Health Care","Passive Sensing","Early Detection","Sleep","Depressive Disorder, Major","NOT_YET_RECRUITING","2026-08-21",{"date":169,"type":170},"2026-08-25","ACTUAL",{"date":172,"type":146},"2026-09",{"date":174,"type":146},"2027-11",{"name":5,"class":6},1]
