Victorian Institute of Sport Assessment questionnaire specifically tailored for greater trochanteric pain syndrome for the Dutch population

Greater trochanteric pain syndrome (GTPS) is a highly prevalent condition characterized by lateral hip and thigh pain. The Victorian Institute of Sport Assessment (VISA) questionnaire specifically tailored for GTPS (VISA-G) questionnaire was developed for the purpose of assessing and quantifying the severity of symptoms related to gluteal tendinopathy or GTPS. It is commonly used in research and clinical settings to evaluate the impact of GTPS on patient function and quality of life. The VISA-G questionnaire was developed for English-speaking populations. Before this questionnaire can be used in non-English-speaking populations, it has to be translated and validated for a particular population. The current study aimed to translate and validate the VISA-G questionnaire for a Dutch-speaking context (VISA-G-Dutch). In this study, we conducted a comprehensive process involving forward and back translation, along with a thorough comparison with other established hip-related questionnaires. The COSMIN checklist was used to ensure uniformity in the validation study. A sample of 100 participants, 50 symptomatic and 50 asymptomatic, completed the VISA-G-Dutch, Harris Hip Score, Hip Disability and Osteoarthritis Outcome Score, Oxford Hip Score, and Nonarthritic Hip Score questionnaires. Internal consistency and test–retest reliability were measured. Construct validity was assessed through positive correlations between the VISA-G-Dutch and gold standard questionnaires. Strong internal consistency and test–retest reliability correlations were found in both the asymptomatic and symptomatic groups. The test–retest reliability also demonstrated strong positive correlations for the symptomatic group. The standard error of measurement was ∼2.3 for the symptomatic group. These results prove that the VISA-G-Dutch is a reliable and valid tool for assessing GTPS and gluteal tendinopathy in Dutch-speaking individuals, providing clinicians with a valuable assessment tool.
