  1. ActScore – Daily phone accelerometer activity score. homDist – Maximum distance (in km) from home traveled that day. radiusMobility – Radius (in km) covering all places visited in a day. percentHome – Percentage of time spent at home each day. DayPlaces – Number of distinct locations visited each day. Variables labeled person-centered reflect day-to-day fluctuations within individuals. Variables labeled mean reflect each participant’s average across the study period.
