The question was whether anxiety, heart rate and skin conductance level just before invasive cardiac procedures could be predicted by anxiety related measures obtained at patients homes approximately 3 weeks before treatment. Trait measures of avoidant coping and defence were provided by sixty-three male and thirty-three female patients who were scheduled for a diagnostic or interventional heart catheterization. In hospital physiological measures were registered continuously during a 20 min interview and subsequently patients reported their anxiety. Results with hierarchical regression analysis showed that sex, age, medical variables and state anxiety at home explained 62% of state anxiety in hospital. Female sex predicted high anxiety in hospital while advanced age predicted low anxiety. Medical variables and measures of coping and defence did not add a significant contribution to this prediction of anxiety. Skin conductance and heart rate measures could not be predicted by the psychological measures collected at home.
问题在于，能否通过在治疗前约3周于患者家中获取的焦虑相关指标，来预测侵入性心脏手术前的焦虑、心率和皮肤电导水平。63名男性和33名女性患者计划接受诊断性或介入性心导管插入术，他们提供了回避应对和防御的特质测量值。在为期20分钟的访谈期间，持续记录住院期间的生理指标，随后患者报告他们的焦虑情况。分层回归分析结果显示，性别、年龄、医疗变量和在家时的状态焦虑解释了住院时62%的状态焦虑。女性性别预示着住院时的高焦虑，而高龄预示着低焦虑。医疗变量以及应对和防御测量值对焦虑的这一预测并未增加显著贡献。在家中收集的心理测量指标无法预测皮肤电导和心率测量值。
