Adherence

Actigraphy provides a valid, cost-effective, and less invasive alternative to polysomnography (PSG) for estimating sleep parameters in population-based epidemiological studies, with agreement rates of 91-93% in adults.

For tracking sleep in real-world settings, use an actigraphy device (wrist-worn accelerometer). It is a validated, non-invasive, and cost-effective method to estimate sleep duration and efficiency, especially when studying large groups or long-term patterns where lab-based PSG is impossible.

GoodSupportsHIGH confidence
In a comprehensive review of the role of actigraphy in studies of sleep and circadian rhythms, Ancoli Israel et al. (2003) reported that, in adult populations, the estimated agreement between PSG and actigraphy ranged from 91 to 93%.
