Hostility is an independent risk factor for coronary heart disease (CHD), and certain hostility subscales (e.g., Barefoot's refined Ho) predict CHD and mortality more powerfully than global hostility measures. An intervention for modifying CHD-predictive hostility components was developed and tested. Twenty-two healthy, high-hostile males, who were matched on age and hostility level, were randomly assigned to either an experimental hostility-reduction treatment group or an information-control group. The experimental group received eight 90-min weekly sessions for altering antagonism, cynicism, and anger reactions. After controlling for pretreatment levels, subjects' group status accounted for an additional and significant 28 and 19% of the variance in improvement of observed Anger-Out scores and Barefoot's refined Ho scores, respectively. Thus, this treatment may reduce CHD-predictive and mortality-predictive hostility levels. The possible clinical significance of these results was tested, and future large-scale and long-term trials are recommended.
敌意是冠心病（CHD）的一个独立危险因素，某些敌意分量表（如Barefoot改良的敌意量表）比整体敌意测量更能有力地预测冠心病和死亡率。一种针对改变预测冠心病的敌意成分的干预措施被开发并进行了测试。22名健康的、敌意程度高的男性，根据年龄和敌意水平进行匹配，被随机分配到实验性敌意降低治疗组或信息对照组。实验组每周接受8次90分钟的课程，以改变对抗、愤世嫉俗和愤怒反应。在控制了预处理水平后，受试者的组别状态分别在观察到的愤怒爆发分数和Barefoot改良的敌意量表分数的改善方差中额外显著占比28%和19%。因此，这种治疗可能会降低预测冠心病和死亡率的敌意水平。对这些结果可能的临床意义进行了测试，并建议未来进行大规模和长期试验。
