To examine biopsychosocial processes that might contribute to the associations among social dominance, gender, and cardiovascular reactivity,.
Social dominance, the tendency to exercise social influence and control, has been positively associated with coronary heart disease (CHD) risk among males, independent of biomedical risk factors and hostility. Exposure to dominant others behaviors also has been associated with elevated CHD risk. For females, submissiveness and a constellation of psychosocial behaviors opposite to urgency and competitiveness have been associated with increased risk for cardiovascular disease (CVD). The studies extend a growing literature concerning the central role of social relationships in health and illness and they test a theoretical model that addresses why social relationships and interpersonally-oriented person variables such as dominance may have differing consequences for the physical well-being of men and women.
The three studies were designed to test a social-contextual model of dominance and cardiovascular stress reactivity (CVR) that synthesized and elaborated earlier models in order to account for (1) cardiovascular consequences of exposure to dominant others and (2) differences in dominant men's and women's cardiovascular responses to social interactions. Because of the disproportionately high rates of CVD among Black Americans, both Black and white men and women were included in the studies.
Using a laboratory social interaction paradigm, study 1 refined and validated a coding system designed to assess dominant and hostile behaviors during dyadic social interaction. Study 2 examined two factors proposed to account for differences in dominant men's and women's cardiovascular responses to social interaction: (1) explicit role demands regarding dominance expression (i.e., the degree to which situations provided clear and salient cues regarding expected and acceptable behavior) and (2) gender composition of the dyad (i.e., same sex versus opposite sex). These two factors were manipulated independently while unacquainted, healthy young adult men and women participated in task-oriented dyadic discussions designed to activate motives to influence; cardiovascular responses were measured during the discussions and preceding rests. Study 3, a secondary analysis of data collected in study 2, examined associations between CVR and exposure to others' dominance. The aforementioned behavioral coding system was used to assess behavioral dominance observed in study 2 and path analytic techniques were used to model associations among CVR, one's own and one's partner's trait and behavioral dominance, gender, and situational factors.

Pathological conditions involving the CARDIOVASCULAR SYSTEM including the HEART; the BLOOD VESSELS; or the PERICARDIUM.
Methods and procedures for the diagnosis of diseases or dysfunction of the cardiovascular system or its organs or demonstration of their physiological processes.
Diseases of long duration and generally slow progression. The four main types of noncommunicable diseases are CARDIOVASCULAR DISEASES (e.g., heart attacks and stroke), CANCER, chronic respiratory diseases (e.g., CHRONIC OBSTRUCTIVE PULMONARY DISEASE and ASTHMA) and DIABETES MELLITUS.
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death.
