Blood-pressure responses during social interaction in high- and low-cynically hostile males
The Cook and Medley Hostility (Ho) Scale has been found to predict the development of coronary heart disease, coronary death, and death from other causes. Enhanced physiological responsiveness among high-Ho subjects may represent a link between hostility and health. The present study examined the systolic and diastolic blood-pressure (SBP, DBP) and heart-rate (HR) responses of high- and low-Ho undergraduate males while they presented their position and listened to their partner's opposing position in a current events discussion task. Compared to low-Ho subjects, the high-Ho group displayed larger SBP and DBP responses. These results and others suggest that cynical hostility is associated with greater physiological responses to interpersonal stressors.
