title: Harassment, hostility, and type A as determinants of cardiovascular reactivity during competition.
abstract: Anger/hostility and Type A behavior have been implicated in elevated cardiovascular reactivity and disease. In the present experiment systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were monitored during conditions of competition alone or in conjunction with goal blocking or harassment. Cardiovascular reactivity was examined as a function of conditions, Type A or B pattern, and various measures of anger/hostility. Harassment elicited significantly elevated SBP and HR changes relative to goal-blocking and control conditions. Type As reliably exceeded Type Bs in magnitude of SBP change during the harassment condition only. However, exploratory analyses correlating anger/hostility measures and cardiovascular reactivity indicated that only subjects scoring high on the Buss-Durkee Hostility Inventory showed significantly elevated SBP reactivity as a function of Type A behavior pattern, rated hostility during the A-B interview, or outward expression of anger assessed by the Framingham Anger-In vs Anger-Out Scale.
