BACKGROUND
The COPD Assessment Test (CAT™) is a new questionnaire that has been developed recently for measuring the COPD patient's health status. It is known to have a good correlation with disease specific health status measured by St. George's Respiratory Questionnaire (SGRQ). For the wider application in clinical practice, it has been validated in many countries. We evaluated the reliability and validity of the translated CAT questionnaire for Thai COPD patients.
METHODS
The study was designed as a cross-sectional validation study enrolling stable Thai COPD patients from three academic centers in Thailand at a single visit. The original CAT questionnaire was translated to Thai through linguistic validation process. The official Thai CAT and SGRQ questionnaires were filled by Thai patients after orientation by the out-patient nurse. The reliability of all items was assessed by Cronbach's formula for coefficient using pooled data from all patients. The validity of the questionnaire was tested using Pearson's correlation with SGRQ.
RESULTS
A total of 98 Thai COPD patients completed the official Thai CAT questionnaire; 83% were male, mean age 71 years (SD 8.2), and % predicted of FEV1 56.6% (SD 20.9). The official Thai CAT questionnaire was shown to have a high internal consistency (Cronbach's α coefficient = 0.853). The assessment of validity of official Thai CAT questionnaire was moderately correlated with that of SGRQ (r = 0.652).
CONCLUSIONS
The official Thai CAT questionnaire has an acceptable reliability and validity. It can be expected to serve as a short and simple tool for assessment of the health status of Thai COPD patients.
背景
COPD 评估测试（CAT）是一种新的问卷，最近已被开发用于衡量 COPD 患者的健康状况。它与圣乔治呼吸问卷（SGRQ）测量的特定疾病健康状况具有良好的相关性。为了更广泛地应用于临床实践，它已在许多国家得到验证。我们评估了翻译后的 CAT 问卷在泰国 COPD 患者中的可靠性和有效性。
方法
该研究设计为一项横断面验证研究，在泰国的三个学术中心的一次就诊中招募稳定的泰国 COPD 患者。原始 CAT 问卷通过语言验证过程被翻译成泰语。在门诊护士指导下，泰国患者填写官方泰语 CAT 和 SGRQ 问卷。使用所有患者的汇总数据，通过 Cronbach 公式评估所有项目的可靠性。使用 SGRQ 的 Pearson 相关性测试问卷的有效性。
结果
共有 98 名泰国 COPD 患者完成了官方的泰语 CAT 问卷；83%为男性，平均年龄 71 岁（SD 8.2），FEV1 预测值为 56.6%（SD 20.9）。官方泰语 CAT 问卷具有较高的内部一致性（Cronbach's α 系数=0.853）。官方泰语 CAT 问卷的评估有效性与 SGRQ 中度相关（r=0.652）。
结论
官方泰语 CAT 问卷具有可接受的可靠性和有效性。它有望成为评估泰国 COPD 患者健康状况的一种简短而简单的工具。
