q3 i? Across reviewed studies, HRV-stress correlations reached large or medium/small effect-size levels in 14 HRV-variable pairs versus 8 uncorrelated pairs, implying moderate concurrent validity for stress measurement. → Hyun Jin Kim 2024

q3 · i? · review · r3

Systematic review of 48 educational studies; the authors coded each HRV-variable pair into four correlation levels by effect-size magnitude and counted 14 L1/L2 pairs versus 8 L4 pairs, concluding "the concurrent validity of HRV data used to measure stress has moderate support."

"For stress measurement, there were 14 L1/L2 pairs and 8 L4 pairs, implying that the concurrent validity of HRV data used to measure stress has moderate support."
