Abstract:
Objective: Determine the validity and reliability of the LIMB-Q scales, Function, and Symptoms in patients with chronic lower extremity wounds. Approach: Cognitive debriefing interviews with people with current or previous wounds were conducted to examine content validity. Scales were field-tested in an international sample of people with chronic lower extremity wounds sourced from an online platform (i.e., Prolific). Psychometric properties were examined using the Rasch Measurement Theory analysis. A test-retest reproducibility study was performed, and construct validity was examined. Results: Content validity was established after 10 cognitive interviews. A total of 233 people with lower extremity wounds (age 19-80 years, mean 39.3) participated in the field test. All 25 items tested demonstrated good fit to the Rasch model with ordered thresholds. One item had a fit residual outside ±2.5, but no items had significant χ2 values after Bonferroni adjustment. Reliability was high with the person separation index, Cronbach alpha, and intraclass correlation coefficient values >0.8. Strong correlations were found between the Function and Symptoms scales and EQ-5D dimensions measuring similar constructs as well as the EQ-5D global score. All hypotheses for construct validity were confirmed. Innovation: Patient-reported outcome measures are an important component of patient-centered care, as they capture the patient\'s perspective in a rigorous and reproducible way. Adding these two scales to the WOUND-Q provides a means to measure function and symptoms associated with lower extremity wounds. Conclusion: These new WOUND-Q scales can be used to measure outcomes important to patients with lower extremity wounds in clinical settings and research studies.
摘要:
目的:确定LIMB-Q量表的有效性和可靠性,功能和症状,慢性下肢伤口患者。
方法:对当前或以前有伤口的人进行认知汇报访谈,以检查内容的有效性。对来自在线平台的慢性下肢伤口患者的国际样本进行了现场测试(即,多产)。使用Rasch测量理论分析检查了心理测量特性。进行了重测重复性研究,并检查结构效度。
结果:内容效度是在10次认知访谈后确定的。共有233名下肢伤口患者(年龄19-80岁,平均39.3)参加了现场测试。测试的所有25个项目都证明了与有序阈值的Rasch模型的良好拟合。一个项目的拟合残差在±2.5之外,但Bonferroni调整后没有项目具有显着的χ2值。人分离指数的可靠性很高,CronbachAlpha,类内相关系数值>0.8。在功能和症状量表与测量相似结构的EQ-5D维度以及EQ-5D全局得分之间发现了强相关性。所有关于结构效度的假设都得到了证实。
方法:PROM是以患者为中心的护理的重要组成部分,因为他们以严格和可重复的方式捕捉患者的观点。将这两个量表添加到WOUND-Q提供了测量与下肢伤口相关的功能和症状的手段。
结论:这些新的WOUND-Q量表可用于在临床和研究中测量下肢伤口患者的重要预后。
