Validation of “Wound QoL” Hebrew version disease‐specific questionnaire for patients with lower extremity ulcerations

Abstract

The slow healing process and high recurrence rate of lower extremity ulcerations (LEU) impose a considerable medical and economic burden and affect quality of life (QoL). Analyses of LEU-related QoL in Israel are limited due to lack of a validated Hebrew disease-specific evaluation instrument. The aim of this study was to validate the disease-specific Hebrew "Wound QoL" questionnaire. The validation of the "Wound QoL" disease-specific instrument, translated from English to Hebrew, was based on a comparison with the valid Hebrew version of the SF12v.2 health-related questionnaire. The convenience sample for the "Wound QoL" validation (n = 32) was obtained from patient populations in the Maccabi Health Services' outpatient clinics at the northern and southern parts of Israel. The study was conducted between June and September 2017. Face/construct validity was accepted by specialists' consensus. Internal consistency assessed by Cronbach's α was .893. Concurrent validity reflected by Pearson's correlations between the tools was in the range of 0.830 to 0.950. The Wound QoL Hebrew version is a valid and reliable instrument suitable for implementation in an Israeli cultural environment.

Assessing the quality of life of people with chronic wounds by using the cross‐culturally valid and revised Wound‐QoL questionnaire

“…6,7 According to the diabetes registry of the Ministry of Health, the estimated annual prevalence of diabetic foot ulcers was 1.2% in Israel. 8 Elderly people are particularly affected by chronic wounds. 3 Thus, the aging population might lead to an increase in the incidence in near future.…”

“…17,18 It was sequentially translated and psychometrically validated into different languages, for example, Dutch, 19 U.S. English, 20 Spanish, 21 Swedish, 22 and Hebrew. 8 Alternative subscale structures have been tested in the Hebrew study. The result deviated from the original structure and included the last item (item 17) in the everyday life category.…”

“…The result deviated from the original structure and included the last item (item 17) in the everyday life category. 8 In addition, there were minor changes of item 10 during the translation progress of the Hebrew Wound-QoL version. 8 Furthermore, researchers adapted wording of item 4 in the Dutch version before the study.…”

Psychometric properties of the Brazilian version of the Wound Quality of Life questionnaire

“…No estudo realizado para verificar as propriedades psicométricas do Wound-QoL, versão original, a correlação foi superior a 0,80 em todos os escores, validade convergente com o FLQA-Wk, alta em todos os escores, e significativa com os questionários Euro QoL Quality of Life questionnaire-5D-3L (EQ-5D--3L) e o Euro QoL-Visual Analogue Scales (EQ-VAS) (4) . Na versão sueca, as correlações foram significativas (p<0,010) (19) , e na hebraica, houve validade concorrente com correlações altas (0,830 a 0,950) (20) .…”

“…No que se refere à confiabilidade do questionário Wound-QoL, obteve-se um alfa de Cronbach global de 0,84, corroborando o estudo de validação da sua versão original, que apresentou um alfa de 0,91 (7) , e com o estudo realizado para verificar suas propriedades psicométricas, que encontrou uma consistência interna >0,80 (4) . Em sua validação sueca, o coeficiente foi de 0,92 para o escore global, e a versão hebrai-ca exibiu valores acima de 0,75 em todos os domínios (19)(20) . No estudo da FLQA-wk, versão original, o resultado foi ≥0,85 (6) , e em sua versão brasileira, foi de 0,86 para a escala total (7) , todos assemelhando-se ao estudo realizado.…”
