Evaluating the Hindi Translation of the Dizziness Handicap Inventory and Its Concurrent Validity With the ABC Scale

Objectives Dizziness is defined as a deceptive or erroneous perception of movement, which can be either non-rotational (such as oscillopsia) or rotational (such as vertigo). These types of movement are frequently caused by injuries to the neurological system and the ears. About 15% of people worldwide suffer from vertigo, a common kind of dizziness. The purpose of the study was to create a series of questionnaires that were easily understood by Hindi speakers and to assess the internal consistency of the translated questionnaires. Materials and Methods A cross-sectional study involving 100 individuals with vestibular pathology-related dizziness, ranging in age from 16 to 75, was carried out. The investigation consisted of two stages. Phase I involves creating and verifying the inventory, while Phase II involves administering the translated inventory. Results The Cronbach’s alpha coefficient was calculated to assess the questionnaire’s internal consistency. With an overall alpha value of 0.92, the DHI-H showed strong internal consistency. The scores for the physical, emotional, and functional subscales were 0.94, 0.93, and 0.99, respectively. To assess the association between the two questionnaires utilised in this study, Kendall’s tau correlation coefficient was also employed. According to the test results, there was a moderate association between the DHI-H score and the ABC-H. Conclusion The findings of the study indicate that the DHI-H possesses good internal reliability. As such, it can be effectively used among Hindi-speaking individuals to assess the impact of dizziness, offering valuable information for both pre- and post-intervention evaluations.
