Özet
Objective: The Dizziness Handicap Inventory (DHI) is a condition specific health status measure for patients with vestibular disease. The purpose of this study is to evaluate the internal consistency, test-retest reliability, construct validity and sensitivity to change of the DHI in people with peripheral vestibular disorder. Materials and Methods: Thirty-three patients with unilateral peripheral vestibular disease were included in the study. For analysis of test-retest reliability, Turkish version of DHI inventory developed by "translation-back translation" method was performed to patients on the day of admission and one week after admission. To assess validity, patients were also evaluated with the visual Analog Scale (VAS), Romberg/tandem Romberg test (eyes open/closed), standing on foam (eyes open/closed), static posturography, five times sit to stand test (FTSTS), timed up to go test (TUG), gait speed, dynamic Gait Index (DGI), functional gait assessment (FGA) and Activities-specific Balance Confidence Scale (ABC). To assess sensitivity to change, 27 patients were involved in a 4 week customized vestibular rehabilitation program. Results: Crohnbach alpha for DHI total was 0.92, Crohnbach alpha for emotional subscore was 0.83, Crohnbach alpha for functional subscore was 0.88 and Crohnbach alpha for physical subscore was 0.67. Although ABC showed significant correlation with DHI (r=0.62-0.53, p<0.05) no such a correlation was determined between DHI and other parameters (p>0.05). Significant improvement was achieved in DHI and other parameters by customized exercise program (p<0.05). Conclusions: Although Turkish DHI scale showed high internal consistency and sensitivity change, its test-retest reliability and validity was relatively poor.
