Abstract: | To examine the relation between hostility and cardiovascular reactivity to stress, 42 undergraduate men were categorized into
high and low hostile groups based on responses to the Cook Medley Hostility Scale. Participants engaged in two laboratory
tasks: a Cognitive Task (mental arithmetic) and a Social Task (confrontation role-play). Cardiovascular measures of heart
rate and blood pressure were obtained throughout rest and task periods and participants provided ratings of state anger and
forgiveness following task completion. Results revealed that low hostile participants exhibited greater systolic blood pressure
(SBP) responses to both tasks than high hostile participants (p < .05), but no significant group differences were observed for heart rate or diastolic blood pressure. High hostile men reported
greater state anger during resting conditions and less forgiveness following completion of tasks than low-hostile counterparts,
but neither of these findings moderated the relation between hostility and SBP reactivity. Higher ratings of forgiveness were
associated with lower SBP reactivity. These findings show that hostility is not always associated with exaggerated cardiovascular
reactivity to stress, and the influence of various moderating factors should be considered in elucidating this relation. |
