“…The subscales also proved to be valid and sensitive to change 15 . Test‐retest reliability of the Wound‐QoL was found to be high, with intraclass correlations between 0.79 and 0.86 16 . As the Wound‐QoL is to be used in numerous countries, international versions are required.…”

People with chronic wounds perceive an impaired health‐related quality of life (HRQoL). For the assessment of HRQoL, valid instruments are needed. Therefore, the Wound‐QoL questionnaire was originally developed and psychometrically validated for use in Germany. As the Wound‐QoL is to be used in numerous countries, international versions are required. Therefore, this study aimed to psychometrically validate the U.S. English Wound‐QoL version. Upon translation into U.S. English, psychometric testing was performed based on cross‐sectional data deriving from the U.S. Wound Registry. Besides descriptive statistics, internal consistency and concurrent validity were tested. In addition, a graded response model was used. The sample consisted of 599 people with chronic wounds of different etiologies. Participants were between 18 and 95 years old, mean age was 63.7 (SD = 15.9) years. Gender was distributed almost equally, with 47.4% female patients. High internal consistency, low floor and ceiling effects of the subscales could be largely confirmed. The internal consistency of the global score was excellent, with α > .9. Concurrent validity between the Wound‐QoL and pain, the surface area of the largest wound, total surface area, and total number of active wounds could be confirmed. In contrast, item response theory (IRT) analyses could not fully confirm the factorial model underlying the Wound‐QoL subscales. Furthermore, the items regarding smell and discharge and the items on problems with hitting the wound against something, climbing stairs and feeling dependent on help from others showed a low item information in their belonging dimensions. In conclusion, the newly validated Wound‐QoL is available for HRQoL measurement in people with chronic wounds in the United States. It showed good psychometric properties, demonstrating its reliability and validity. Therefore, the instrument may be used to assess HRQoL in clinical practice. However, IRT analyses showed that the instrument may benefit from future refinement.

“…For this purpose, the Wound-Qol questionnaire 12 has been developed based on three more extensive questionnaires for patients with wounds (the Cardiff Wound Impact Schedule (CWIS) 13 , the Freiburg Life Quality Assessment for wounds (FLQA-W) 11 and the Wuerzburg Wound Score (WWS) 15 . The Wound-QoL 12,15,16 consists of 17 questions from which a total scale score and three subscale scores can be calculated with higher values indicating worse HRQoL. The subscale 'body' is derived from items 1 to 5 (e.g., "my wound hurt", "the wound has affected my sleep"), the subscale 'psyche" is derived from items 6 to 10 (e.g., "the wound has made me unhappy", "I have been afraid of knocking the wound"), and subscale 'everyday life' is derived from items 11 to 16 (e.g., "I have had trouble moving around because of the wound", "the wound has limited my leisure activities") Item 17 does not belong to neither of the subscales.…”

BackgroundChronic wounds have a major impact on patients’ health-related quality of life (HRQoL). Therefore, measuring HRQoL is an indispensable part of the treatment of patients with chronic wounds. The aim of this study was to translate and validate the Wound-QoL, a wound-specific HRQoL questionnaire, in a Dutch population. MethodsThe Wound-QoL was translated into Dutch according to the international standards. Patients with chronic wounds were asked to complete questionnaires at baseline (T0) and after 6 weeks (T1), including Wound-QoL, EQ-5D-3L (a generic questionnaire to measure HRQoL) and a visual analogue scale (VAS) measuring wound pain. If patients were not able to complete the questionnaire by themselves, it was read out to them by a nurse. Further data were obtained from medical records.ResultsOf the 120 patients included, 64 (53.3%) completed the questionnaire by themselves. To 55 patients (45.8%), the questionnaire was read out. The internal consistency of the Wound-QoL global score was high at both time points (T0: Cronbach’s α=0.89, T1: Cronbach’s α=0.92). The item selectivity for global score ranged from r=0.25 to r=0.77 at T0 and from r=0.40 to r=0.79 at T1. Overall, the self-completion and read-out subgroups showed similar internal consistency and item selectivity scores. With regard to convergent validity, significant correlations were found between Wound-QoL and EQ-5D-3L (T0: r=-0.45, p<0.001, T1: r=-0.50, p<0.001) as well as between Wound-QoL and pain VAS (T0: r=0.23, p=0.012, T1: r=0.37, p=0.001) at both time points. Responsiveness analyses showed significant correlations between changes in Wound-QoL and changes in EQ-5D-3L (r=-0.37, p<0.001), pain VAS (r=0.24, p=0.044) and wound size (r=0.24, p=0.013). The self-completion and read-out subgroups showed differences in convergent validity and responsiveness. ConclusionsThe results indicate that the Dutch version of the Wound-QoL has positive psychometric properties. However, more research is needed to further explore the differences between self-completed and read-out questionnaires.

Overall, the self-completion and read-out subgroups showed similar internal consistency and item selectivity scores. With regard to convergent validity, significant correlations were found between Wound-QoL and EQ-5D-3L (T0: r = − 0.45, p < 0.001, T1: r = − 0.50, p < 0.001) as well as between Wound-QoL and pain VAS (T0: r = 0.23, p = 0.012, T1: r = 0.37, p = 0.001) at both time points.
