DTRACResearch context
INSPIRE is presented in the context of understanding daily emotion and behavior among North Korean defectors. The pilot in the presentation instead describes 28 community-adult completers and a 14-day collection protocol, with no disease-specific recruitment criterion. Completers were aged 22–71. Do not relabel the pilot sample as a sample of North Korean defectors.
The example uses Galaxy phones and Galaxy Watches. Figures and schedules on this page come from pages 7 and 14 of the September 17, 2026 MD4BD presentation.
Collection protocol
| Area | Presentation description |
|---|---|
| EMA | Once each in early morning, morning, afternoon, and evening; 60-minute response window |
| Reminders | Every 15 minutes if incomplete, up to three reminders |
| Voice | 19:00–23:59; two recordings per day, 30–60 seconds each |
| Sensors | Acceleration, device motion, location, screen/battery, call state |
| Health | Exercise, sleep, heart rate, steps, blood pressure, glucose, temperature, oxygen saturation |
These are study-specific items from the presentation, not the current default registry's automatic collection list. Check the individual data pages for current code status.
Reported pilot results
| Item | Mean of participant completion rates |
|---|---|
| Surveys | 88.7% |
| Voice diaries | 88.5% |
| Cognitive tasks | 91.8% |
| Sleep records | 85.3% |
A separate aggregate reports sensor records present on 454 / 455 participant-days. Do not recalculate that denominator as 28×14 or apply it to other completion rates. Detailed formulas and aggregation definitions require the original study data. Record presence does not establish complete raw data from every sensor.
