Dizziness Handicap Inventory
Also known as: DHI
The Dizziness Handicap Inventory (DHI) is a 25-item self-report questionnaire designed to measure the functional, emotional, and physical effects of dizziness and balance disorders on daily life. Developed by Jacobson and Newman in 1990, it has become a standard tool for assessing dizziness-related handicap in clinical and research settings. The DHI is valuable for tracking disability progression and treatment response in vestibular patients.
Key highlights
- Multidimensional assessment capturing physical, emotional, and functional consequences of dizziness—not just symptom severity
- Excellent reliability (test-retest intraclass correlation coefficient >0.90) and strong internal consistency (Cronbach's α = 0.89)
- Extensively validated across diverse vestibular populations (BPPV, bilateral vestibular loss, central disorders, migraine-related dizziness)
- Simple, quick self-report format; no equipment required
- Validated MCID (≈18 points) enables detection of clinically meaningful change in individuals

When to use it
The DHI is used for patients with vestibular disorders, benign paroxysmal positional vertigo (BPPV), Ménière disease, vestibulitis, central dizziness, and post-concussive balance dysfunction. It is particularly valuable for baseline assessment, monitoring treatment response in vestibular rehabilitation programs, and evaluating disability in clinical trials. Suitable for primary care, otolaryngology, neurology, and physical therapy settings.
Strengths & limitations
- Multidimensional assessment capturing physical, emotional, and functional consequences of dizziness—not just symptom severity
- Excellent reliability (test-retest intraclass correlation coefficient >0.90) and strong internal consistency (Cronbach's α = 0.89)
- Extensively validated across diverse vestibular populations (BPPV, bilateral vestibular loss, central disorders, migraine-related dizziness)
- Simple, quick self-report format; no equipment required
- Validated MCID (≈18 points) enables detection of clinically meaningful change in individuals
- Yes/no format with trichotomous response (sometimes=2) may miss subtle symptom fluctuation; ordinal scale limits parametric analysis
- Does not distinguish between objective balance deficit and anxiety-driven avoidance; high emotional subscale may reflect secondary depression rather than vestibular impairment
- Developed for adult vestibular populations; validity in pediatric and geriatric cohorts less extensively studied
- Does not assess vertigo frequency, duration, or triggers; relies solely on handicap perception

Frequently asked
What is the minimal clinically important difference (MCID) for the DHI?
The MCID is approximately 18 points. This represents the smallest change in score that patients perceive as meaningful improvement or deterioration. A change of 18 points or greater is recommended as evidence of meaningful clinical change in individual patients.
Can the DHI be used in children?
The original DHI was validated in adult populations. A pediatric version (DHI for Children) was adapted by Horak et al. (2000) and is suitable for ages 5–16 years. Use age-appropriate versions; direct application of adult DHI in young children is not recommended.
How does DHI compare to other vestibular disability measures?
The DHI is brief (25 items) compared to the Activities-Specific Balance Confidence (ABC) scale (16 items) or Vertigo Symptom Scale (12–15 items), yet provides multidimensional assessment. The Vestibular Activities and Participation (VAP) measure assesses participation restrictions; DHI emphasizes handicap. Both are complementary.
Is the DHI affected by mood or anxiety?
Yes, the emotional subscale (9 items) is sensitive to anxiety and depression, which commonly co-occur with dizziness. High emotional subscale scores may reflect secondary anxiety rather than vestibular dysfunction. When mood disorder is suspected, administer concurrent mood screening (GAD-7, PHQ-9).
