Differentiating shame- and guilt-proneness with heart rate variability in Chinese young adults

A high proneness to experience shame and guilt has been associated with psychopathology. Despite their similarity, shame- and guilt-proneness have different psychological and neurobiological correlates. The present study aims to compare the physiological correlates between shame- and guilt-proneness. Resting heart rate variability (HRV), a peripheral biomarker of emotion dysregulation and psychopathology, was measured in a sample of 60 Chinese young adults with two sessions of electrocardiogram recording. Proneness to shame and guilt were measured by the Test of Self-Conscious Affect 3. Hierarchical linear modeling indicated that guilt-proneness was positively associated with HRV while shame-proneness was not. Our findings implied that shame- and guilt-proneness have different relations with HRV. The distinct physiological relations are discussed with respect to the adaptive/maladaptive nature of shame- and guilt-proneness.
