Welcome to the Dizziness Handicap Inventory (DHI) Calculator. This tool is designed to help individuals assess the self-perceived handicap resulting from dizziness. The DHI is a widely used and validated questionnaire in clinical settings to quantify the impact of dizziness on daily life across physical, emotional, and functional domains.
Please answer the following 25 questions based on how your dizziness impacts you:
Understanding the Dizziness Handicap Inventory (DHI)
The Dizziness Handicap Inventory (DHI) is a self-assessment questionnaire used to measure the perceived impact of dizziness and unsteadiness on daily life. Developed by Jacobson and Newman in 1990, it has become a standard tool in audiology, otolaryngology, and physical therapy for both clinical assessment and research.
The DHI consists of 25 questions, each targeting a specific aspect of how dizziness affects an individual. These questions are categorized into three subscales, providing a nuanced understanding of the handicap:
- Functional (F) Scale (9 items): Assesses difficulties with daily activities such as walking, bending, driving, or household chores.
- Emotional (E) Scale (9 items): Evaluates emotional responses to dizziness, including frustration, fear, anxiety, and depression.
- Physical (P) Scale (7 items): Measures the impact of specific movements or positions that provoke dizziness, such as head movements or getting in and out of bed.
How the DHI Calculator Works
For each of the 25 questions, you are asked to select one of three responses:
- Yes: This response indicates a significant impact and is scored as 4 points.
- Sometimes: This response indicates a moderate impact and is scored as 2 points.
- No: This response indicates no impact and is scored as 0 points.
After answering all questions, the calculator sums up the points from your responses to provide a total DHI score. The maximum possible score is 100 points (25 questions * 4 points/question).
Interpreting Your DHI Score
The total DHI score provides an indication of the severity of the self-perceived handicap due to dizziness. While interpretations can vary slightly between clinicians and studies, common guidelines are:
- 0 - 14 points: No or Mild Handicap
- 16 - 30 points: Moderate Handicap
- 32 - 100 points: Severe Handicap
It's important to remember that these are general guidelines. A higher score indicates a greater self-perceived handicap from dizziness, suggesting a more significant impact on your quality of life.
Why is the DHI Important?
The DHI is a valuable tool for several reasons:
- Patient-Centered Assessment: It focuses on the patient's subjective experience of dizziness, which is crucial for understanding its real-world impact.
- Treatment Planning: Scores can help healthcare professionals identify specific areas (physical, emotional, functional) where a patient struggles, guiding tailored treatment plans (e.g., vestibular rehabilitation, psychological support).
- Monitoring Progress: Repeated DHI assessments over time can track changes in a patient's perceived handicap, helping to evaluate the effectiveness of interventions.
- Research: It provides a standardized measure for clinical trials and studies on dizziness and balance disorders.
