French Translation and Validation of the Victorian Institute of Sports Assessment for Gluteal Tendinopathy Questionnaire

Introduction: Developed in 2015, the VISA-G is the first Patient Reported Outcome Measure
(PROM) tool specifically designed to measure the severity of disability associated with greater
trochanteric pain syndrome. There is currently no French version of the VISA-G questionnaire.
Objective: The purpose of this work was to translate the VISA-G questionnaire into French
(VISA-GF) and to test its psychometric performances.
Design: Cross-sectional study, validation study.
Setting: Clinics in Liège, Belgium and in France.
Patients: Participants suffering from greater trochanteric pain syndrome and control
asymptomatic participants.
Intervention: Not applicable
Main outcome: French translation of the VISA-G and psychometric performances of the
questionnaire tested using internal consistency, construct validity and test-retest reliability
with a seven-day interval.
Results: The eight items of the VISA-G questionnaire were translated without any difficulties.
106 participants (median age 53 (58-64) years old, 65 women (61.3%)) were included in the
psychometric validation study. The questionnaire discriminates well between pathologic
(n=52) and asymptomatic participants (n=54). Moreover, we found a good internal consistency
and excellent test-retest reliability for the VISA-GF questionnaire. We also confirmed the
construct validity and did not find any floor or ceiling effects.
Conclusions: The VISA-GF has been shown to be a valid and reliable way to measure the
severity of disability associated with greater trochanteric pain syndrome in French speaking
participants.
