Why the study?
Wearable sensors are increasingly used to collect longitudinal and ecologically valid psychophysiological data, but ensuring their measurement fidelity and reliability remains critical.
This tutorial provides a framework and statistical tools for systematically quantifying the measurement reliability of wearable heart rate sensors in psychophysiological research.
Offers framework for assessing wearable reliability; leaves open validation and adoption in cardiovascular research and practice.
Wearable sensors are quickly making their way into psychophysiological research, as they allow collecting longitudinal and ecologically valid data. The present tutorial considers fidelity of physiological measurement with wearable sensors, focusing on reliability. We elaborate why ensuring reliability for wearables is important and offer statistical tools for assessing wearable reliability for between participants and within-participant designs. The framework offered here is illustrated using several brands of commercially available heart rate sensors. Our hope is that by systematically quantifying measurement reliability, researchers will be able to make informed choices about specific wearable devices and measurement procedures that meet their research goals.
