The Quality of Recovery-15 scale (QoR-15) is an easy-to-use score for assessing the quality of post-operative recovery.
The primary aim of the present study was to translate the QoR-15 into the Chinese language and validate it. The secondary aim was to compare it with the Post-operative Quality Recovery Scale (PQRS).
The Chinese version of the QoR-15 (QoR-15C) was developed according to the methods adopted by the International Quality of Life Assessment project. A total of 470 patients undergoing surgery and general anesthesia completed the QoR-15C and the PQRS before or on the day of surgery, and on post-operative days (POD)-1, -3, and -30. To validate the QoR-15C, we assessed validity, reliability, responsiveness, and clinical feasibility and compared them with those of the PQRS.
Convergent validity showed the Pearson's r coefficient of the QoR-15C with visual analog scale and the PQRS to be 0.63 and 0.10, respectively. Predictive validity showed it had significant correlations with duration of anesthesia, duration of operation, time in post-anesthesia care unit, time in intensive care unit, and length of hospital stay. Discriminant validity showed it differed between patients who had a good or poor recovery, and decreased with increasing grades (indicating difficulty and complexity) of surgery. The intraclass correlation coefficient, split-half coefficient, and Cronbach's α were 0.99, 0.70, and 0.76, respectively. The standardized effect size ranged from 0.85 to 1.20, and the standardized response mean ranged from 0.93 to 1.27. Compared with the QoR-15C, the PQRS may have inferior convergent validity (0.36 vs. 0.63), and split-half reliability (0.63 vs. 0.70). Furthermore, the PQRS took longer to complete: 4.20 (standard deviation 0.79) versus 1.57 (standard deviation 0.65) min.
Similar to the original English version, the QoR-15C reveals satisfactory psychometric properties. Furthermore, it may be a more valid, reliable, and easy-to-use scale than the PQRS.
术后恢复质量-15量表（QoR-15）是一种用于评估术后恢复质量的易于使用的评分工具。
本研究的主要目的是将QoR-15翻译成中文并进行验证。次要目的是将其与术后质量恢复量表（PQRS）进行比较。
根据国际生活质量评估项目采用的方法制定QoR-15的中文版（QoR-15C）。共有470例接受手术和全身麻醉的患者在手术前或手术当天以及术后第1天、第3天和第30天完成了QoR-15C和PQRS。为了验证QoR-15C，我们评估了其效度、信度、反应度和临床可行性，并将它们与PQRS的相应指标进行比较。
聚合效度显示，QoR-15C与视觉模拟量表和PQRS的Pearson相关系数分别为0.63和0.10。预测效度显示，它与麻醉持续时间、手术持续时间、麻醉后监护病房停留时间、重症监护病房停留时间和住院时间显著相关。区分效度显示，它在恢复良好或恢复不佳的患者之间存在差异，并且随着手术分级（表示难度和复杂性）的增加而降低。组内相关系数、分半系数和Cronbach's α分别为0.99、0.70和0.76。标准化效应量范围为0.85至1.20，标准化反应均值范围为0.93至1.27。与QoR-15C相比，PQRS的聚合效度可能较差（0.36对0.63），分半信度也较差（0.63对0.70）。此外，完成PQRS所需的时间更长：4.20（标准差0.79）分钟对1.57（标准差0.65）分钟。
与原始英文版类似，QoR-15C显示出令人满意的心理测量特性。此外，它可能是一种比PQRS更有效、更可靠且易于使用的量表。
