Purpose: The objective of current study is to construct validity and reliability of Vestibular Disorders Activities of Daily Life In Turkish language. And also It was aimed to determine effects of symptoms on activities of daily life In patients with vestibular disorders. Methods: Subjects with peripheral vestibular disorders and chronic vertigo complaints were included In the study. Subjects with neurologic, systemic and physical problems and also subjects with acute Meniere disease were excluded from the study. Turkish version of scale was applied to 233 subjects over 18 ages. However, statistical analyses were done with fully completed 175scales. Results: Internal consistency reliability was found to significant for total Cronbach' alpha=0.96; and for subscales of functional=0.92, ambulatlon=0.93 and instrumental=0.89. Test-retest correlation coefficient was 0.93 for total score (for functional, ambulation and instrumental was 0.85,0.70 and 0.95). There were no significant difference between applications (p>0.05). Bartlett test (x2=4640.05; df=300) p=0.00 results were significant and KMO result (0.90) was above the critic value. Factor analysis yielded one factor explaining 57.32%of variance. The corrected Item-total correlation coefficients ranged from 0.64 to 0.86. Significant correlation (r=0.518) was found between Turkish VADL and Turkish DHI (p<0.05). Discussion: Turkish VADL reliability scores were similar to original VADL scores. It was shown that Turkish VADL is a reliable scale in evaluation of adult patients with vertigo and dizziness.
