Health status is increasingly recognized as an important outcome for the management of chronic heart failure (CHF). The Chronic Heart Questionnaire (CHQ) is valid, reliable, and responsive but is interview led. The aim of this study was to develop a self-reported version (CHQ-SR) to aid practical application of the questionnaire. The validity, repeatability, and responsiveness were investigated.
Patients with CHF (n = 54) were recruited; 50 completed both CHQs-the self-reported (CHQ-SR) and the interview led (CHQ-IL)-within a 2-week period with the order of administration alternated. Patients (n = 43) completed the CHQ-SR twice within a 2-week period. Construct validity was assessed using the Medical Outcomes Short Form 36 (SF-36) questionnaire, and the responsiveness was assessed using a randomized controlled trial of exercise rehabilitation versus usual care.
The CHQ-SR was comparable but not interchangeable with the CHQ-IL. There were no significant differences between the mean scores for each domain on 2 administrations of the CHQ-SR, except for a small improvement in the emotional function domain. There were moderate-to-high correlations between the domains of the CHQ-SR and relevant components of the SF-36. The CHQ-SR was as responsive as the CHQ-IL when applied to a randomized controlled trial of exercise rehabilitation versus usual care in patients with CHF.
The CHQ-SR is comparable with the CHQ-IL and is repeatable. It has construct validity with other health status measures and is responsive. The advantage of not requiring interviewer time and associated cost provides for a practical administration of the questionnaire.
健康状况越来越被认为是慢性心力衰竭（CHF）管理的重要结果。慢性心脏问卷（CHQ）是有效、可靠且敏感的，但需要面谈。本研究旨在开发一种自我报告版本（CHQ-SR），以帮助问卷的实际应用。调查了其有效性、可重复性和敏感性。
招募了 CHF 患者（n=54）；50 名患者在 2 周内完成了 CHQ 的自我报告（CHQ-SR）和面谈（CHQ-IL）两种版本，两种版本的执行顺序交替。43 名患者在 2 周内完成了 CHQ-SR 的两次测试。使用医疗结局简表 36 项（SF-36）问卷评估结构效度，使用运动康复与常规护理的随机对照试验评估敏感性。
CHQ-SR 与 CHQ-IL 相似但不可互换。CHQ-SR 的两次测试中，除情感功能领域略有改善外，每个领域的平均得分均无显著差异。CHQ-SR 的各个领域与 SF-36 的相关成分之间存在中度至高度相关性。当应用于 CHF 患者的运动康复与常规护理的随机对照试验时，CHQ-SR 与 CHQ-IL 一样敏感。
CHQ-SR 与 CHQ-IL 相似且可重复。它与其他健康状况测量具有结构效度，并且敏感。不需要面谈者时间和相关成本的优势为问卷的实际管理提供了便利。
