Abstract:
This study examined the impact of person-centered communication on bereaved young adults' physiological stress responses when they talked about the death of their parent. Heart rate variability - indexed by the standard deviation of the normal-to-normal intervals (SDNN), the root mean square of successive differences (rMSSD), and the heart rate variability index (HRVi) - was monitored before, during, and after the interaction as an objective measure of stress reactivity and recovery. The final sample included 69 subjects, and they conversed with research confederates who provided varying levels of person-centered support. The results showed that participants who received highly person-centered support experienced faster stress recovery, as indicated by increased HRVi, compared to those who received moderately or low person-centered support. Bereaved adults' SDNN during the interaction was positively associated with subjective evaluations of cognitive reappraisal, emotional improvement, and support quality. The discussion highlights the significance of supportive interactions on physiological, psychological, and emotional well-being.
