The utility of the Hospital Anxiety and Depression Scale (HADS) as a screening instrument for coronary care patients following acute myocardial infarction (MI) was investigated. A maximum likelihood factor analysis was conducted on the HADS to determine its psychometric properties and utility in 194 patients. Though internal reliability estimations of the anxiety and depression sub-scales were found to be acceptable, the expected two-factor solution failed to emerge from the data set. The three-factor solution that emerged isolated dimensions representing depression and distinct factors of trait anxiety and state anxiety. The utility of the HADS in the routine assessment of the affective state of patients following acute MI may be extended by the use of the instrument in predicting mortality and morbidity.
研究了医院焦虑抑郁量表（HADS）作为急性心肌梗死（MI）后冠心病护理患者筛查工具的效用。对194例患者的HADS进行了最大似然因子分析，以确定其心理测量特性和效用。尽管焦虑和抑郁子量表的内部信度估计值可以接受，但数据集中并未出现预期的两因素解决方案。出现的三因素解决方案分离出了代表抑郁以及特质焦虑和状态焦虑不同因素的维度。通过使用该量表预测死亡率和发病率，HADS在急性心肌梗死后患者情感状态常规评估中的效用可能会得到扩展。
