Trait anger and hostility predict the development of coronary heart disease, and systemic inflammation may partly mediate this association. In a sample of 94 middle-aged and older married couples, we replicate research showing a within individuals (i.e., actor effect) association of trait hostility with high sensitivity C-reactive protein (hsCRP). As a novel extension of that research, the present study also examined the association of individuals' trait hostility with their partners' hsCRP (i.e., partner effect). Controlling for potential confounds, trait hostility, measured with the Buss-Perry Aggression Questionnaire, was significantly associated with both participants' own hsCRP, b=.0528 (SE=.0196), p=.008 and their partners' levels b=.0473 (SE=.0194), p=.016. Hence, the inflammatory correlates of trait hostility occur not only within individuals but between them, as well. The effects of unhealthy personality traits may extend to intimate partners and possibly other social network members.
特质愤怒和敌意预示着冠心病的发展，而全身炎症可能部分介导了这种关联。在一个由94对中老年已婚夫妇组成的样本中，我们重复了一项研究，该研究表明特质敌意与高敏C反应蛋白（hsCRP）之间存在个体内部（即行为者效应）关联。作为该研究的一个新扩展，本研究还考察了个体的特质敌意与其伴侣的hsCRP之间的关联（即伴侣效应）。在控制了潜在的混杂因素后，用布斯-佩里攻击性问卷测量的特质敌意与参与者自身的hsCRP显著相关，b = 0.0528（标准误 = 0.0196），p = 0.008，与他们伴侣的水平也显著相关，b = 0.0473（标准误 = 0.0194），p = 0.016。因此，特质敌意的炎症相关不仅发生在个体内部，也发生在个体之间。不健康人格特质的影响可能会延伸到亲密伴侣以及其他可能的社会网络成员。
