DHI Scoring Explained

A comprehensive guide to understanding how the Dizziness Handicap Inventory is scored, what the numbers mean, and how to interpret your results for better communication with healthcare providers.

Basic Scoring Methodology

Response Values

No
0 points
Sometimes
2 points
Yes
4 points

Total Score Calculation

The total DHI score is calculated by adding up all individual question scores:

Total Score = Σ (Question 1 + Question 2 + ... + Question 25)

Range: 0-100 points

With 25 questions and a maximum of 4 points per question, the highest possible score is 100.

DHI Subscale Scoring

The DHI consists of three subscales that measure different aspects of how dizziness affects your life. Each subscale contains specific questions and has its own maximum score.

Physical Subscale
7 questions • Maximum: 28 points

Measures how dizziness affects physical movements and activities.

Questions Include:

  • • Question 1: Looking up
  • • Question 4: Walking in supermarket
  • • Question 7: Reading
  • • Question 11: Quick head movements
  • • Question 13: Turning over in bed
  • • Question 17: Walking on sidewalk
  • • Question 25: Bending over

Physical Score = Sum of questions 1,4,7,11,13,17,25

Emotional Subscale
9 questions • Maximum: 36 points

Assesses the emotional and psychological impact of dizziness.

Questions Include:

  • • Question 2: Feeling frustrated
  • • Question 6: Social activities
  • • Question 9: Afraid to leave home

  • • Question 21: Feeling handicapped
  • • Question 23: Feeling depressed

Emotional Score = Sum of questions 2,6,9,10,15,16,18,21,23

Functional Subscale
9 questions • Maximum: 36 points

Evaluates how dizziness impacts daily tasks and functional abilities.

Questions Include:

  • • Question 3: Travel restrictions
  • • Question 5: Getting in/out of bed
  • • Question 8: Ambitious activities
  • • Question 12: Avoiding heights
  • • Question 14: Strenuous housework
  • • Question 19: Walking in dark
  • • Question 20: Staying home alone
  • • Question 22: Family relationships
  • • Question 24: Job responsibilities

Functional Score = Sum of questions 3,5,8,12,14,19,20,22,24

Score Interpretation Examples

Example 1: Mild Handicap
Total Score: 18/100

Subscale Breakdown:

  • • Physical: 8/28 (29%)
  • • Emotional: 4/36 (11%)
  • • Functional: 6/36 (17%)

Interpretation:

This patient experiences primarily physical symptoms with minimal emotional or functional impact. Symptoms are manageable and don't significantly interfere with daily life.

Example 2: Moderate Handicap
Total Score: 48/100

Subscale Breakdown:

  • • Physical: 16/28 (57%)
  • • Emotional: 18/36 (50%)
  • • Functional: 14/36 (39%)

Interpretation:

This patient shows balanced impact across all domains, with slightly higher physical and emotional scores. Indicates need for comprehensive treatment addressing multiple aspects.

Example 3: Severe Handicap
Total Score: 76/100

Subscale Breakdown:

  • • Physical: 24/28 (86%)
  • • Emotional: 28/36 (78%)
  • • Functional: 24/36 (67%)

Interpretation:

This patient experiences severe impact across all domains, with particularly high physical and emotional scores. Requires intensive, multidisciplinary treatment approach.

Clinical Significance and Usage

Minimal Clinically Important Difference (MCID)

Research suggests that a change of 18 points or more in the total DHI score represents a clinically meaningful improvement or worsening.

Subscale Analysis Benefits
  • Targeted Treatment: High physical scores may indicate need for vestibular rehabilitation
  • Psychological Support: High emotional scores suggest counseling may be beneficial
  • Functional Training: High functional scores indicate need for activity modification training
  • Progress Tracking: Monitor improvement in specific domains over time
