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 alpha = 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.
