Development and Validation of the DHI
The DHI was developed to assess the impact of dizziness, validated through studies ensuring reliability and effectiveness in clinical use, providing a standardized tool for evaluating dizziness-related challenges.
2;1 History and Creation of the DHI
The Dizziness Handicap Inventory (DHI) was created in 1990 by Jacobson and colleagues to quantify the impact of dizziness on patients’ lives. It was designed to measure self-perceived handicap across physical, functional, and emotional domains. The development aimed to provide a reliable tool for clinicians to assess dizziness-related challenges effectively. Its creation marked a significant advancement in vestibular rehabilitation and research.
2.2 Validation Studies and Reliability
The DHI has undergone extensive validation, demonstrating strong internal consistency and test-retest reliability. Jacobson’s 1990 study established its reliability, supported by subsequent research, including MM Tanashyan’s 2022 study. Cross-cultural adaptations, such as the Brazilian version, further validate its universal applicability. These studies confirm the DHI’s effectiveness in assessing dizziness-related disability across diverse populations, ensuring its reliability as a clinical and research tool.
Structure and Administration of the DHI
The DHI is a 25-item questionnaire divided into three subscales: physical, functional, and emotional aspects of dizziness. Available in PDF format, it is self-administered, with patients rating difficulties on a 0-4 scale. Instructions guide respondents to focus on dizziness-related challenges, ensuring clarity and consistency in administration.
3.1 The 25-Item Questionnaire
The DHI consists of 25 items, each addressing specific challenges related to dizziness. These items are divided into three subscales: physical (7 items), functional (9 items), and emotional (9 items). Each question uses a 4-point Likert scale, ranging from “No problem” (0) to “Severe problem” (4). This structure ensures a comprehensive assessment of dizziness’s impact on daily life and emotional well-being. The PDF format ensures clarity and ease of use in clinical settings.
3.2 Instructions for Completing the DHI
The DHI is a self-administered questionnaire where patients rate their difficulties due to dizziness on a 0-4 scale. Respondents select answers based on how dizziness affects their daily activities, emotional state, and physical function. The PDF version provides clear instructions, ensuring ease of completion. Patients are advised to answer based on their current condition, allowing clinicians to assess the impact of dizziness accurately.
Scoring and Interpretation of the DHI
The DHI scores range from 0 to 100, with higher scores indicating greater disability. Scores are categorized as mild (10-30), moderate (31-52), and severe (53-100).
4.1 How to Calculate DHI Scores
To calculate DHI scores, sum the responses for all 25 items, with each question scored from 0 (no problem) to 4 (severe problem). The total score ranges from 0 to 100, where higher scores indicate greater handicap. Scores are categorized as mild (10-30), moderate (31-52), and severe (53-100). This scoring system provides a clear measure of dizziness-related disability, aiding in clinical assessment and monitoring progress over time.
4.2 Interpreting the Results
DHI scores range from 0 to 100, with higher scores indicating greater handicap. Mild handicap is 10-30, moderate is 31-52, and severe is 53-100. Scores above 10 suggest significant impact on daily life. Clinicians use these categories to assess disability levels and monitor treatment progress, ensuring appropriate interventions for patients with varying degrees of dizziness-related challenges.
