The Victorian Sports Assessment Institute-Achilles Tendinopathy Questionnaire (VISA-A): Chinese cross-cultural adaptation and psychometric validation.

PURPOSE

We aimed to create a standardized cross-cultural adaptation of the simplified Chinese version of VISA-A, test its reliability and validity and conduct exploratory factor analysis on the correlation between items.

METHODS

According to international recommendations for the cross-cultural adaptation of questionnaires, after considering the opinions of patients, we translated and revised the English version to create a simplified Chinese version of the questionnaire. We recruited healthy subjects in the general specialty of one university (n = 90) and the physical education specialty of another university (n = 89), and we recruited patients with Achilles tendinopathy in a third group (n = 85). Reliability was evaluated by calculating test-retest reliability and internal consistency, validity was evaluated by exploring structural and criterion validity (correlation with the physical function and body pain items of the SF-36), and responsiveness was evaluated by calculating area under the receiver operating characteristic curve (AUC).

RESULTS

The simplified Chinese version of the VISA-A had no ceiling or floor effects. Four common factors were extracted and explained by the exploratory factor analysis. The test-retest reliability (ICC = 0.97) and internal consistency (Cronbach's alpha = 0.84) were adequate. The questionnaire had moderate correlations with the physical function and body pain items of the SF-36. The AUC was 0.9407.

CONCLUSION

The simplified Chinese version of the VISA-A had good reliability and validity and excellent responsiveness, but the factorial structure is not inconsistent with the dimensions of the original version. It can be used to assess and manage patients with Achilles tendinitis in the Chinese culture.
