Translation, reliability, and validity of the Turkish version of the Victorian Institute of Sports Assessment For Gluteal Tendinopathy (VISA-G) questionnaire in individuals with greater trochanteric pain syndrome

Background: Greater trochanteric pain syndrome (GTPS) is a common cause of lateral hip pain. Objective: The objectives of this study were to translate the Victorian Institute of Sports Assessment for Gluteal Tendinopathy (VISA-G) questionnaire into the Turkish language and to examine its reliability and validity. Methods: 108 individuals (45 female, 63 male) participated in the translation and the reliability and validity analysis. The original VISA-G questionnaire was translated into Turkish language using Beaton guidelines. The Turkish version of the VISA-G, Harris Hip Score (HHS), Oswestry Disability Index (ODI), Oxford Hip Score (OHS), and International Physical Activity Questionnaire (IPAQ) were applied to 108 individuals with GTPS for convergent validity. The VISA-G was retested to investigate its reliability after one week. Results: The VISA-G had a good correlation with HHS (r = 0.694, p < .001), ODI (r = −0.659, p < .001), OHS (r = 0.678, p < .001), and IPAQ (r = 0.440, p < .001). The reliability and internal consistency were excellent (ICC (2,1) value = 0.943; Cronbach’s α = 0.946, respectively). And no floor and ceiling effects were revealed related VISA-G. Conclusion: The Turkish version of the VISA-G has good validity and excellent reliability. It can be used in clinical and research practices in the Turkish population with GTPS.
