慢性阻塞性肺疾病(COPD)评估测试(CAT)是一份简短的问卷，有助于评估COPD受试者的健康状况。然而，关于猫是否可以作为圣乔治呼吸问卷(SGRQ)的合适替代品，仍然存在争议。本研究调查了CAT和SGRQ的信度和得分分布，并评估了每个问卷的哪些因素对健康状况有影响。本研究共纳入109名来自同一中心的COPD稳定期受试者。每个受试者都完成了肺功能测试、运动测试和以下自填式问卷：基线呼吸困难指数、医院焦虑和抑郁量表、CAT和SGRQ。CAT和SGRQ总分的内部一致性均较好(克朗巴赫α系数分别为0.890和0.933)。CAT总分与SGRQ总分呈显著正相关(R=0.668，P<；0.001)。CAT评分与肺功能、呼吸困难、运动能力、心理因素等参数的相关性不如与SGRQ总分的相关性。多元回归分析和主成分分析均显示SGRQ总分和CAT总分之间略有差异。在辨别健康状况方面，猫与SGRQ相似。然而，我们证明了CAT评估的结果可能与SGRQ测量的结果略有不同。
The chronic obstructive pulmonary disease (COPD) assessment test (CAT) is a short questionnaire that has facilitated health status measurements in subjects with COPD. However, it remains controversial as to whether the CAT can be used as a suitable substitute for the St George’s Respiratory Questionnaire (SGRQ). This study investigated the reliability and score distributions of the CAT and SGRQ and evaluated which factors contributed to health status for each questionnaire. A total of 109 consecutive subjects with stable COPD from a single center were enrolled in this study. Each subject completed pulmonary function tests, exercise tests, and the following self-administered questionnaires: the Baseline Dyspnea Index, the Hospital Anxiety and Depression Scale, the CAT, and SGRQ. Internal consistencies of CAT and SGRQ total scores were both excellent (Cronbach’s α coefficients =0.890 and 0.933). Statistically significant correlations were observed between CAT and SGRQ total scores (R=0.668, P<0.001). Correlations of CAT scores with parameters related to pulmonary function, dyspnea, exercise performance, and psychological factors were inferior to correlations with those parameters with SGRQ total scores. Both multiple regression analyses and principal component analyses revealed that there were slight differences between SGRQ total scores and CAT scores. The CAT is similar to SGRQ in terms of discriminating health status. However, we demonstrated that what is assessed by the CAT may differ slightly from what is measured by SGRQ.
