Ethnicity and Type D personality as predictors of heart rate variability

Abstract

This study examined the relationship between Type D personality and heart rate variability (HRV) during three guided imagery experiences (baseline, stressful, and uplifting) in a non-medical sample. The interaction between African-American ethnicity and Type D personality was predictive of both low and high frequency HRV during stressful imagery experiences. The importance of identifying group influences when assessing psychological and cardiovascular health was discussed.
