摘要

背景:肌肉疏松症在癌症患者中很普遍,对生活质量有负面影响。然而,通用工具无法捕捉到肌肉疏松症对生活质量的轻微影响。肌肉疏松症生活质量(SF-SarQoL)问卷的简易版被开发为评估肌肉疏松症对老年人生活质量影响的有效工具。目的:本研究旨在探讨中文 SF-SarQoL 在结直肠癌患者中的临床测量特性,尤其是其检测生活质量变化的能力:方法:使用 SF-SarQoL 及其他问卷对 408 名计划接受手术的结直肠癌患者进行了纵向调查。随后对其中的 341 名患者进行了术后 1 个月的随访。研究考察了 SF-SarQoL 的临床特性,包括信度(内部一致性)、效度(结构效度、并发效度)、灵敏度(检测变化的能力、判别能力)以及下限效应和上限效应:结果:SF-SarQoL 的内部一致性是可以接受的(Cronbach's alpha = .94 和 McDonald's omega = .94)。莫肯分析法证实了总分和每个项目都具有很强的可扩展性。并发有效性分析表明,SF-SarQoL 与肌肉相关和健康相关问卷的得分有显著相关性。SF-SarQoL显示出足够的灵敏度,因为它能很好地检测出生活质量的变化,具有中等的效应大小(Cohen's d = 0.56),并能通过接收者操作特征曲线分析区分肌肉疏松和非肌肉疏松患者(曲线下面积 = 0.73,95% CI [0.66,0.79])。没有观察到下限或上限效应:结论:中文 SF-SarQoL 在结直肠癌术前患者中表现出良好的临床测量特性,对捕捉术后生活质量的变化具有足够的灵敏度。

Clinimetric Properties of the Chinese Short Form of the Sarcopenia Quality of Life Questionnaire in Patients With Cancer.

Background: Sarcopenia, prevalent in patients with cancer, negatively affects quality of life. However, generic tools are unable to capture the minor effects of sarcopenia on quality of life. The short-form version of the Sarcopenia Quality of Life (SF-SarQoL) questionnaire was developed as an efficient tool to assess the impact of sarcopenia on quality of life in older adults. However, its clinimetric properties in patients with cancer remain unknown.

Purpose: This study was designed to examine the clinimetric properties of the Chinese SF-SarQoL in patients with colorectal cancer, particularly with regard to its ability to detect changes in quality of life.

Methods: A longitudinal survey was conducted using the SF-SarQoL and other questionnaires on 408 patients with colorectal cancer planning to undergo surgery. Follow-up was subsequently conducted on 341 of these patients 1 month after surgery. The clinimetric properties of the SF-SarQoL were examined, including reliability (internal consistency), validity (construct validity, concurrent validity), sensitivity (ability to detect changes, discriminative ability), and floor and ceiling effects.

Results: The internal consistency of the SF-SarQoL was found to be acceptable (Cronbach's alpha = .94 and McDonald's omega = .94). Strong scalability of the total score and each item was confirmed using Mokken analysis. Concurrent validity analyses indicate the SF-SarQoL is significantly correlated with muscle-related and health-related questionnaire scores. The SF-SarQoL showed adequate sensitivity due to its good ability to detect changes in quality of life with a moderate effect size (Cohen's d = 0.56) and discriminate between sarcopenic and nonsarcopenic patients (area under the curve = 0.73, 95% CI [0.66, 0.79]) using receiver operating characteristic curve analyses. No floor or ceiling effects were observed.

Conclusions: The Chinese SF-SarQoL exhibits good clinimetric properties in preoperative patients with colorectal cancer and is sufficiently sensitive to capture changes in quality of life after surgery.
