An exploratory factor analysis of the HAD was carried out in 568 cancer patients. Two distinct, but correlated, factors emerged which corresponded to the questionnaire's anxiety and depression subscales. The factor structure proved stable when subsamples of the total sample were investigated. The internal consistency of the two subscales was also high. These results provide support for the use of the separate subscales of the HAD in studies of emotional disturbance in cancer patients.
对568名癌症患者进行了医院焦虑抑郁量表（HAD）的探索性因素分析。出现了两个不同但相关的因素，分别对应于该问卷的焦虑和抑郁分量表。当对总样本的子样本进行调查时，因素结构证明是稳定的。两个分量表的内部一致性也很高。这些结果为在癌症患者情绪障碍研究中使用医院焦虑抑郁量表的单独分量表提供了支持。
