Patients with idiopathic pulmonary fibrosis (IPF) experience impaired health-related quality of life (HRQoL). Several tools have been developed to objectively assess HRQoL in this patient population, but none are in use in routine clinical practice.

To develop a rapid, specific tool that can be used for patients with IPF during routine clinic visits.

A novel and simple five-item numerical rating scale was developed and compared with two other previously validated tools. 100 consecutive patients with IPF managed at a centre for interstitial lung disease were recruited to complete the Raghu scale for pulmonary fibrosis (R-Scale-PF), King's Brief Interstitial Lung Disease questionnaire (K-BILD), and the EuroQol Five-Dimensional Five-Level questionnaire (EQ-5D-5L) in addition to pulmonary function and 6-min walk tests.

All 100 patients successfully completed the three HRQoL tools with 53 completing them again at follow-up visits. Internal consistency was high (Cronbach's α 0.825) with minimal floor/ceiling effect. Concurrent validity of the R-Scale-PF was moderate to high compared with the K-BILD (r=–0.713) and the EQ-5D-5L (r=–0.665). Concurrent validity was moderate with physiologic measures (forced vital capacity, r=–0.307, 6-min walking distance, r=–0.383). The R-Scale-PF demonstrated good known-groups validity when comparing scores across stages of disease severity.

The R-Scale-PF correlates well with the K-BILD and EQ-5D-5L. It is hoped that this novel simple numerical rating scale tool, subject to validation in patients from other centres, will provide an opportunity to objectively measure HRQoL in routine clinical practice for patients with IPF.

特发性肺纤维化 (IPF) 患者的健康相关生活质量 (HRQoL) 受损。已经开发了几种工具来客观地评估该患者群体的 HRQoL，但没有一种工具在常规临床实践中使用。

开发一种快速、具体的工具，可用于 IPF 患者在常规门诊就诊期间。

开发了一种新颖而简单的五项数字评分量表，并与其他两个先前验证的工具进行了比较。招募了 100 名在间质性肺疾病中心管理的连续 IPF 患者，以完成肺纤维化 Raghu 量表 (R-Scale-PF)、King's Brief 间质性肺疾病问卷 (K-BILD) 和 EuroQol 五维五- 除了肺功能和 6 分钟步行测试之外的水平问卷 (EQ-5D-5L)。

所有 100 名患者均成功完成了三个 HRQoL 工具，其中 53 名患者在随访中再次完成了这些工具。内部一致性很高（Cronbach's α 0.825），地板/天花板效应最小。与 K-BILD ( r =–0.713) 和 EQ-5D-5L ( r =–0.665)相比，R-Scale-PF 的同时效度为中到高。生理测量的同时效度适中（用力肺活量，r =–0.307，6 分钟步行距离，r =–0.383）。在比较疾病严重程度不同阶段的分数时，R-Scale-PF 证明了良好的已知组有效性。

R-Scale-PF 与 K-BILD 和 EQ-5D-5L 相关性很好。希望这种新颖的简单数字评分量表工具，在其他中心的患者中得到验证，将为 IPF 患者的常规临床实践中客观测量 HRQoL 提供机会。
