本研究探讨了敌意和心血管反应的维度之间的独立关系的实验室任务，有和没有骚扰。根据Cook和Medley敌意（Ho）量表评分（大于24或小于14），选择了53名年龄在18至26岁之间、父母无心血管疾病史的男性。因素分析的六个单独的措施的敌意/愤怒导致两个因素的解决方案;因素1代表敌对的敌意和因素2代表神经质的敌意。结果显示，敌对性敌对因子分越高，收缩压（SBP）和前臂血流量（FBF）变化越大，对骚扰的收缩压恢复越差。此外，高因子分的神经质敌意显着预测更大的FBF变化的骚扰。其他相关性分析显示，心血管反应与自我报告的负面影响呈正相关，但仅适用于任何一个维度得分较高的受试者。这些结果与最近的证据相一致，表明只有对抗性敌意可能与冠状动脉疾病的严重程度增加有关，人际冲突的程度缓和了冠状动脉易感行为和心血管反应之间的关联。
: The present study examined the independent relationships between dimensions of hostility and cardiovascular responses to a laboratory task with and without harassment. Fifty-three males, aged 18 to 26, with a negative parental history of cardiovascular disease were selected on the basis of their scores on the Cook and Medley Hostility (Ho) scale (greater than 24 or less than 14). Factor-analysis of six separate measures of hostility/anger resulted in a two-factor solution; Factor 1 representing antagonistic hostility and Factor 2 representing neurotic hostility. Results showed that high factor scores on antagonistic hostility were significantly associated with greater systolic blood pressure (SBP) and forearm blood flow (FBF) changes and poorer SBP recovery to harassment. In addition, high factor scores on neurotic hostility significantly predicted greater FBF changes to harassment. Additional correlational analysis showed that cardiovascular responses were positively associated with self-reported negative affects but only for subjects with high scores on either dimension. These results are in agreement with recent evidence suggesting that only antagonistic hostility may be related to increased severity of coronary artery disease and that the degree of interpersonal conflict moderates the association between coronary-prone behaviors and cardiovascular responses.
