The Wound-QoL questionnaire has been tested in a previous study, indicating that the instrument is a reliable and valid measurement for the assessment of HRQoL in chronic wounds. The aim of this study was to examine the test-retest reliability of the Wound-QoL. Patients were asked to complete the Wound-QoL twice within 3-7 days. Next to descriptive statistics, internal consistency was determined. Test-retest reliability was calculated with the intraclass correlation coefficient. The data showed ICCs between 0.79 and 0.86, which can be considered evidence of excellent reliability. Another indicator of very good reliability, high internal consistency of both global score, and subscale scores were found. The availability of the Wound-QoL provides a step forward in allowing measurement of the HRQoL in chronic wounds. The instrument is fit for use to measure outcomes in clinical trials and as well to assess treatment outcomes in routine practice.
伤口生活质量问卷已在先前的一项研究中进行了测试，表明该工具是评估慢性伤口患者健康相关生活质量的可靠且有效的测量方法。本研究的目的是检验伤口生活质量问卷的重测信度。要求患者在3至7天内两次完成伤口生活质量问卷。除描述性统计外，还确定了内部一致性。用组内相关系数计算重测信度。数据显示组内相关系数在0.79至0.86之间，这可被视为可靠性极佳的证据。还发现了另一个可靠性非常好的指标，即总体得分和子量表得分的内部一致性都很高。伤口生活质量问卷的可用性为测量慢性伤口患者的健康相关生活质量向前迈进了一步。该工具适用于测量临床试验中的结果，也适用于评估常规实践中的治疗结果。
