TIME Study

Temporal influences in movement and exercise (TIME) study

In TIME study, we developed a mobile and smartwatch application to gather information on factors that might influence physical activity, sedentary behavior, and sleep patterns in young adults. The app gathers information on health behaviors using ecological momentary assessment, smartwatch-based microEMA, and passive sensors on phone and the smartwatch. Note: This is a work in progress with an ongoing data collection.
