N2 - The Wound-QoL is an often used reliable and valid measure, originally developed in Germany. It has been sequentially translated and validated for other languages/countries, for the measurement of health-related quality of life (HRQoL) in patients with chronic wounds. However, a study from the United States postulated its benefits from further adaptations. Furthermore, some patients struggled to provide an answer for some of the items. We aimed to test the cross-cultural structure and psychometric performance of the questionnaire to suggest necessary revisions. This cross-sectional analysis of existing data sets included 1185 patients from Germany, the US, the Netherlands, Spain, Sweden, and Israel. Patients in the U.S. Wound Registry completed the Wound-QoL during routine care. Different studies comprised the data collection in the other countries. Almost half of the patients were women (48.4%). Furthermore, 42.6% were diagnosed with leg ulcers. Their average age was 66 years. We used a confirmatory factor analysis and an unconstrained graded response model. We revised and shortened the Wound-QoL from 17 to 14 items. In addition, we supported the cross-cultural metric invariance of the revised Wound-QoL questionnaire. The new version with 14 items and three dimensions revealed good psychometric properties with Cronbach's alpha (α) of 0.913 for the total score, and 0.709-0.907 for different dimensions. Furthermore, we provided strict invariance for different clinical variables. In conclusion, the revised Wound-QoL is a reliable and cross-cultural instrument to measure the HRQoL on patients with chronic wounds. Future studies should analyse the revised Wound-QoL for convergent validity with generic HRQoL questionnaires as well as for determining its sensitivity to clinical change.
