The Reliability and Validity of the Turkish Version of the European Evaluation of Vertigo Scale

Abstract

Objective: The aim of this study is to make validity and reliability analysis with the Turkish adaptation of the European Evaluation of \rVertigo Scale (EEV-TR). Material and Methods: Patients who applied to \rthe otorhinolaryngology department with vestibular complaints were included in the study (n=100). EEV scale was adapted into Turkish from the \roriginal language. EEV-TR questionnaire and Vertigo Symptom Scale-TR \r(VSS-TR) assessments of the patients were performed twice, at baseline and \ron the 4th week. Results: One hundred participants (65 women, 35 men) \rwith a mean age of 50.87±14.94 were enrolled in the research. The mean age \rof 35 (35%) male patients was 55.51±12.41, and the mean age of 65 (65%) \rfemale patients was 48.5±15.75. Seventy seven patients were diagnosed \rwith BPPV, 18 patients with Meniere’s disease, and 5 patients with vestibular neuronitis. The Cronbach’s alpha value of the EEV-TR was calculated \ras 0.712 in the baseline measurement and 0.864 at the 4th-week measurement. The intraclass correlation coefficient of the EEV-TR was 0.835. A \rsignificant correlation was found between EEV-TR and VSS-TR baseline \rmeasurements (r=.411, p=0.001) and between 4th-week measurements \r(r=.649, p?0.001). EEV-TR factorial accumulation was consistent with the \roriginal scale. The BPPV discriminative power of the EEV-TR scale was \rmedium to high (p<0.01). Conclusion: EEV-TR is a valid and reliable scale \rthat can be used in the evaluation and follow-up of patients with vestibular \rcomplaints.
