Notes. SES = socioeconomic status; RSA = respiratory sinus arrhythmia; PPS = perceived physiological stress; adjusted R2 reported; sample sizes for each reactivity model: cortisol (n = 336), heart rate (n = 320); RSA (n = 184); PPS (n = 251); F statistics pertain to model results, β statistics refer to standardized coefficients of individual predictors.
