Dizziness Handicap Inventory (DHI)

Overview

The Dizziness Handicap Inventory (DHI) is a 25-item self-report questionnaire that measures the self-perceived handicap caused by dizziness or unsteadiness — not the dizziness itself, but the toll it takes on a person’s function, emotions, and physical confidence day to day. It’s one of the most widely used patient-reported outcome measures in vestibular practice, and is often the first standardised measure completed at a patient’s initial vestibular assessment.

The DHI deliberately separates impairment (the sensation of dizziness) from disability (what that sensation stops a person from doing, and how it makes them feel). Two patients with identical vestibular test results can score very differently on the DHI — and that gap is often exactly what a clinician needs to know to plan treatment and predict who is likely to struggle with day-to-day function.

History

The DHI was developed by Gary P. Jacobson and Craig W. Newman and published in 1990 in the Archives of Otolaryngology–Head & Neck Surgery. At the time, most tools available for dizziness assessment focused on describing or quantifying vertigo symptoms directly (frequency, severity, triggers), with little standardised way to capture the broader functional and psychological impact.

Jacobson and Newman built the DHI around three subscales — Functional, Emotional, and Physical — deliberately structured so clinicians could see not just whether a patient was handicapped by dizziness, but in which domain the greatest impact fell. The instrument was validated on patients with a range of vestibular diagnoses and quickly became a standard outcome measure in otolaryngology and vestibular rehabilitation, where it remains one of the most frequently cited PROMs in the vestibular literature more than three decades later.

Indications

The DHI is used wherever dizziness or imbalance is a presenting complaint, including:

• Peripheral vestibular disorders — benign paroxysmal positional vertigo (BPPV), vestibular neuritis, Ménière’s disease, and unilateral or bilateral vestibular hypofunction.
• Central and functional dizziness — vestibular migraine and persistent postural-perceptual dizziness (PPPD), where the emotional subscale often carries particular weight.
• Post-concussion and mild traumatic brain injury, where dizziness is a common and persistent symptom.
• Pre- and post-vestibular rehabilitation therapy, as the standard outcome measure for tracking change over a course of treatment.
• Falls-risk assessment in older adults, often used alongside the ABC Scale or Berg Balance Scale.
• Pre-operative and post-operative vestibular surgery (e.g. vestibular schwannoma resection, labyrinthectomy), to document functional impact before and after intervention.

How It’s Scored

Each of the 25 items is answered Yes (4 points), Sometimes (2 points), or No (0 points). Items are drawn from three subscales:

• Functional (9 items) — effects on daily activities: travel, walking, reading, housework, social participation.
• Emotional (9 items) — frustration, embarrassment, fear, depression, and concentration difficulties related to the problem.
• Physical (7 items) — provocation by specific head and body movements: looking up, bending over, quick head turns, turning over in bed.

Scores are summed across all 25 items to produce a total score out of 100, where higher scores indicate greater self-perceived handicap. Subscale scores can also be calculated separately by summing only the items in that domain, which is often more clinically informative than the total alone.

Interpretation bands

Cut-points vary slightly by source, but the following bands are widely used as a general guide:

As with the ABC Scale, the DHI has a reported minimal detectable change (MDC) in the region of 18 points in several vestibular rehabilitation studies — meaning smaller shifts between assessments may reflect measurement variability rather than a true change in status, and should be interpreted alongside the clinical picture.

What It Tells the Clinician

• Separates disability from impairment. A patient may report only mild vertigo but severe functional and emotional handicap, or the reverse — information that changes how a treatment plan is prioritised.
• Highlights the dominant domain. A high Emotional subscale relative to Physical and Functional may point toward a significant anxiety or PPPD component, prompting a different, more graded and psychologically-informed rehabilitation approach.
• Flags provoking movements. High scores on Physical-subscale items (looking up, bending, quick head turns) can guide which specific vestibular rehabilitation exercises to prioritise.
• Tracks recovery over a course of care. Because it’s quick to re-administer, the DHI is commonly used at intake and at set intervals through vestibular rehabilitation to demonstrate — and document — functional improvement.
• Supports referral and case complexity decisions. Persistently high Emotional-subscale scores despite improving Physical and Functional scores can flag patients who may benefit from a combined vestibular and psychological approach.
