The validation of measured and self-reported sleep duration and perceived sleep quality: an empirical study with three generations of smartwatches (opens in new tab)

IntroductionSleep is routinely assessed in the management of mental health conditions. Wearable technologies like smartwatches offer a non-intrusive method to quantitatively measure sleep. However, there are limited empirical benchmarks for sleep duration and sleep quality measured by wearables against user reports. This study aims to evaluate the concordance between user-reported and smartwatch-measured hours of sleep and sleep quality.MethodsParticipants were recruited from two decentralize...
