- 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.
