Mobility, activity and social interactions in the lives of healthy older adults (MOASIS project)

In this project we monitor activity data from 150+ community-dwelling older adults aged 65+ years over 30 days using a custom-built sensor (“uTrail”) including a GPS tracker, an accelerometer, and a microphone to capture mobility (i.e., spatial activity), physical activity and social activity in daily life. In addition, during the first 2 weeks of wearing the uTrail, participants respond to seven daily prompts from a smartphone and record their current experiences, perceptions and feelings as well as perform a short numerical updating task as a measure of momentary working memory performance in daily life. The goal of the project is to examine within-person activity profiles both within and across domains, within-person couplings between activities, self-reports and cognition, and the degree to which a wide range of dispositional quality of life and performance measures can explain interindividual differences in the intraindividual profiles.
