Abstract:
|
Wearables provide a much more complete view of physical activity, sleep, and circadian rhythmicity and their association with mental health disorders, most of the studies use different devices placed at different parts of the body. Thus, there is a critical need of harmonizing these assessments across clinical and population samples to facilitate more comprehensive cross-study analyses. We will present three novel harmonization approaches that efficiently addresses this challenge.
