Translation, cross-cultural adaptation and validation of the Bulgarian version of the Dizziness Handicap Inventory

摘要

Purpose The aim of the present study was the translation, cross-cultural adaptation and validation of the Dizziness Handicap Inventory in Bulgarian language (DHI-BG). Methods Ninety-seven vestibular patients (19 men and 78 women, mean age 45.08 +- 13.85 years) took part in the investigation. All participants were asked to fill in the DHI-BG. Internal consistency was estimated using Cronbach's alpha and item-total correlation, reproducibility by calculating Bland-Altman's limits of agreement and intraclass correlation coefficients (ICCs). Associations were estimated by Spearman's correlation coefficients.
