Note. TSST-Trier Social Stress Test; ΔSBP-change in systolic blood pressure; ΔDBP-change in diastolic blood pressure; ΔHR—change in heart rate; AUCi-area under the curve with respect to increase; RSA- Respiratory sinus arrhythmia (measure of heart rate variability); prep-preparatory phase of the Trier. Because of non-normal distributions and small sample size, p-values and betas (standardized) are reported for the log-transformed self-compassion score, cortisol, and the diastolic blood pressure change score for the speech task as well as square-root transformations for the change in heart variables. The heart rate variability vairables functioned best without transformation. Adjusted models included terms for gender (male = 1, female = 0) and race (white = 1, other = 0).
