Abstract

Abstract : The VISA‐A questionnaire has proven to be a valid and reliable tool for assessing severity of Achilles tendinopathy (AT). The aim was to translate and cross‐culturally adapt the VISA‐A questionnaire for a Danish‐speaking AT population, and subsequently perform validity and reliability tests. Translation and following cross‐cultural adaptation was performed as translation, synthesis, reverse translation, expert review, and pretesting. The final Danish version (VISA‐A‐DK) was tested for reliability on healthy controls ( n = 75) and patients ( n = 36). Tests for internal consistency, validity, and structure were performed on 71 patients. VISA‐A‐DK showed good reliability for patients ( r = 0.80 ICC = 0.79) and healthy individuals ( r = 0.98 ICC = 0.97). Internal consistency was 0.73 (Cronbach's alpha). The mean VISA‐A‐DK score in AT patients was 51 [47–55]. This was significantly lower than healthy controls with a score of 93 (90–95). Criterion validity was considered good when comparing the scores of the Danish version with the original version in both healthy individuals and patients. VISA‐A‐DK is a valid and reliable instrument and has shown compatible to the original version in assessment of AT patients. VISA‐A‐DK is a useful tool in the assessment of AT, both in research and in a clinical setting.
