Indigenous context of vertigo: translation and validation of dizziness handicap inventory for diagnosis and evaluation of patients in Pakistani hospitals

Abstract

Purpose The purpose of this paper is to focus on the indigenous need for public health challenges being faced by the patients in Pakistan because of vertigo symptoms. Vertigo or benign paroxysmal positional vertigo is described as short episodes of dizziness (spinning sensations) that are caused because of movements of head in varying directions. Various published accounts have linked vertigo to psychological and psychiatric symptoms, which include stress, anxiety and depression. The aim of present study is to examine the validity and reliability of Dizziness Handicap Inventory (DHI) Urdu version that is vital in the diagnosis, evaluation and treatment of patients coming in hospitals. Design/methodology/approach This present study included two segments, namely, preliminary and main study. Preliminary study results indicated that the overall scale had high internal consistency of DHI Urdu version α = 0.95. The overall scale retained a high test-retest correlation tested over a period of 15 days (r = 0.93). Main study was performed on 222 vestibulocochlear disorder patients having chief complaints of tinnitus and vertigo, age ranged from 18 to 89 (M = 46.14; SD = 16.64) and recruited from various hospitals of Islamabad and Rawalpindi, Pakistan. Purposive sampling technique was applied based on cross-sectional design. Findings Significant correlations were noted between dizziness symptoms rating on the translated scale. Confirmatory factor analysis was used to determine the structure of the scales; an orthogonal rotation (Varimax) was conducted on the data collected from patients. A three-factor solution was obtained for DHI, the factors obtained were associated to the subscales vestibular handicap, vestibular disability and visuo-vestibular disability, demonstrating a strong factorial validity in the Pakistani cultural context. Originality/value Vertigo is a symptom that initiates various psychological issues among vestibulocochlear disorder patients (patients having ear related problems) around the world and therefore the investigated inventory offers an initial assessment for the severity of dizziness. Current research will help in the development of indigenous measures to ascertain the severity of the symptoms triggering various other mental health-related issues.
