The use of digital tools to measure physiological and behavioural variables of potential
relevance to mental health is a growing field sitting at the intersection between computer …

Actigraphy, a method for inferring sleep/wake patterns based on movement data gathered
using actigraphs, is increasingly used in population-based epidemiologic studies because …

Wrist worn raw-data accelerometers are used increasingly in large-scale population
research. We examined whether sleep parameters can be estimated from these data in the …

Wrist-worn accelerometers are increasingly being used for the assessment of physical
