简介和目的：堪萨斯城心肌病问卷（KCCQ）专门用于评估慢性心力衰竭（CHF）患者的生活质量。本研究的目的是评估西班牙语版KCCQ的信度、效度和对变化的反应性。方法：对315例CHF患者进行多中心研究。在基线、24周和26周对患者进行评估。使用KCCQ、明尼苏达州心衰患者生活问卷（MLHFQ）和SF-36短表。通过检查第24周至第26周的重测和内部一致性测量来评估稳定患者（n = 163）的可靠性。通过确定KCCQ评分随纽约心脏协会（NYHA）功能分类的变化，以及与MLHFQ和SF-36相似域的评分进行比较，在基线（n = 315）评估有效性。通过确定效应大小，评估在基线和第24周（n = 31）之间经历显著临床改善的患者对变化的反应性。结果：不同域的信度系数在0.70 ~ 0.96之间。KCCQ平均分与NYHA功能分级差异有统计学意义（P < 0.001）。与其他问卷上的可比域的相关性是可以接受的（例如，对于物理限制，它们在0.77和0.81之间）。在24周观察到的改善的子样本中大多数KCCQ评分的变化对应于中等效应大小（即0.4-0.6）。结论：西班牙语版KCCQ具有良好的度量特性（即效度、信度和反应性），适合用于评估西班牙CHF患者的生活质量。(C) 2010西班牙心脏病学会。Elsevier Espana, s.l.出版，版权所有。
Introduction and objectives: The Kansas City Cardiomyopathy Questionnaire (KCCQ) is specifically designed to evaluate quality of life in patients with chronic heart failure (CHF). The purpose of this study was to assess the reliability, validity, and responsiveness to change of the Spanish version of the KCCQ.Methods: The multicenter study involved 315 patients with CHF. Patients were evaluated at baseline and at weeks 24 and 26. The KCCQ, the Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the Short Form-36 (SF-36) were administered. Reliability was assessed in stable patients (n = 163) by examining test-retest and internal consistency measures between weeks 24 and 26. Validity was evaluated at baseline (n = 315) by determining how KCCQ scores varied with NewYork Heart Association (NYHA) functional class and by comparing scores with those on similar domains of the MLHFQ and SF-36. Responsiveness to change was assessed in patients who experienced significant clinical improvement between baseline and week 24 (n = 31) by determining the effect size.Results: Reliability coefficients ranged between 0.70 and 0.96 for the different domains. Mean KCCQ scores varied significantly with NYHA functional class (P < .001). Correlations with comparable domains on the other questionnaires were acceptable (e.g. for physical limitation, they were between 0.77 and 0.81). The changes observed at 24 weeks in the majority of KCCQ scores in the subsample that improved corresponded to a moderate effect size (i.e. 0.4-0.6).Conclusions: The Spanish version of the KCCQ has good metric properties (i.e. validity, reliability and responsiveness), which make it suitable for use in evaluating quality of life in Spanish CHF patients.
