Abstract: Background: Parts of brain and internal ear forms the vestibular system. It helps to relay sensory information require for controlling balance and eye movements. If there is any lesion or pathology to this system may lead to vestibular disorder. Along with common symptoms, patients have decreased independence in self-care and mobility skills. Scales available to measure quality of life in patients with vestibular disorder are DHI, ABC, VHQ, and VADL. There are total 28 activities mentioned in the VADL scale which is further administer in different 3 sub skills including functional, ambulation and instrumental. The scale has been translated, reliable and valid in multiple languages. However no psychometrically validated Gujarati version is available. Aim: To assess the reliability and validity of Guajarati version of vestibular disorder activities of daily living scale (VADL) among the subjects with vestibular disorder. Methods: 200 subjects with vestibular disorder were recruited for the study, which was carried out under 3 primary phase. Phase 1 was translation of the scale into Gujarati language. Subsequently it was tested for understandability of the prefinal version. Later on to the final version was tested to find out its reliability and validity. Result: Intraclass Correlation Coefficient (ICC) had used to determine test re-test reliability, total score of VADL-G was 0.992, which indicated excellent reliability. Content validity was examined by Content Validity Index (CVI). The value of I-CVI for 28 items is 0.80 to 1.00 and S-CVI/Ave of 0.98 that showed excellent content validity for VADL-G. Conclusion: On the basis of findings, (VADL-G) is a reliable and valid screening tool for assessing ADL difficulties among Gujarati population with vestibular disorder.
