背景：堪萨斯城心肌病问卷（KCCQ）是最近开发的一种疾病特异性工具，用于测量慢性心力衰竭（CHF）患者的健康相关生活质量（HRQoL），无论其病因如何。目的：评估 KCCQ 在既往心肌梗死（MI）患者中的信度和效度。方法和结果：在 754 名存活出院的心肌梗死患者中，我们从患者的病历中收集了临床数据。急性心肌梗塞发生两年半后，我们向 548 名仍然活着的患者邮寄了一份自填问卷。回应率为74%。使用 Cronbach's alpha 评估的内部一致性可靠性范围为 0.66-0.95。使用组内相关系数 (ICC) 进行测试的重测信度在 0.41-0.83 范围内。 KCCQ 和简表 36 (SF-36) 的相似和不相似量表之间的关联模式支持 KCCQ 的收敛/发散有效性。四个 KCCQ 量表和两个总结分数区分了心力衰竭药物治疗和未药物治疗的患者，以及不同水平的左心室射血分数 (LVEF)，支持不同组的有效性。 结论：挪威版 KCCQ 显示出可接受的信度和横断面效度，支持使用该问卷来衡量心肌梗死后与健康相关的生活质量。 (C) 2004 年欧洲心脏病学会。由 Elsevier B.V. 出版。保留所有权利。
Background: The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a recently developed disease-specific instrument for measuring health-related quality of life (HRQoL) in patients with chronic heart failure (CHF) regardless of aetiology.Aim: To assess the reliability and validity of the KCCQ in patients with previous myocardial infarction (MI).Methods and results: In 754 myocardial infarction patients who were discharged alive, we collected clinical data from the patients' medical records. Two and a half years after the acute myocardial infarction, we mailed a self-administered questionnaire to the 548 patients still alive. The response rate was 74%. Internal consistency reliability, assessed with Cronbach's alpha, ranged 0.66-0.95. Test-retest reliability, tested with an intraclass correlation coefficient (ICC), ranged 0.41-0.83. The pattern of association between similar and dissimilar scales of the KCCQ and Short Form 36 (SF-36) supported the convergent/divergent validity of the KCCQ. Four of the KCCQ scales and the two summary scores discriminated between patients with and without medication for heart failure, and between different levels of left ventricular ejection fraction (LVEF) supporting different groups validity.Conclusions: The Norwegian version of the KCCQ showed acceptable reliability and cross-sectional validity, which support the use of this questionnaire to measure health-related quality of life after myocardial infarction.
