Cross-cultural adaptation and measurement of psychometric properties of the Filipino version of Victorian Institute of Sports Assessment Ankle Instability (VISA-A) questionnaire for achilles tendinopathy

ABSTRACT

BACKGROUND@#Achilles Tendinopathy (AT) is common in elite and recreational athletes involved in sports such as running and jumping. The severity of this condition can be assessed using the VISA-A questionnaire. However, this is originally developed in English. This has been translated to several languages, but there is no translation and cross-cultural adaptation yet to Filipino. This study aims to translate, cross-culturally adapt the VISA-A questionnaire to Filipino, and examine its psychometric properties.@*METHOD@#The translation and validation process were in accordance with the guidelines set by Beaton et al., and Sousa et al. The psychometric properties were assessed on n= 8 healthy and n= 8 symptomatic athletes.@*RESULTS@#The VISA-A questionnaire exhibited excellent face validity (100% agreement), content validity (Item-Content Validity Index and Scale-Content Validity Index= 1.00), construct validity (U= 2.50, p= 0.001), and concurrent validity (r= 0.90, p= 0.001). The items have good internal consistency (α= 0.80) and showed excellent reliability (ICC= 0.94; 95% CI 0.73–0.99).@*CONCLUSIONS@#The cross-cultural adaptation of the Filipino version of VISAA (VISA-A-Fil) was successful. Preliminary psychometric testing showed that the VISA-A-Fil questionnaire is a valid and reliable tool that measures the severity of AT. However, there is still a need to explore its full psychometric properties.
