title: [Cross-cultural adaptation and validation of the Dizziness Handicap Inventory: Argentine version].
abstract: OBJECTIVE
  The Dizziness Handicap Inventory is a useful tool for quantifying self-perceived handicap in patients with vertigo, dizziness or unsteadiness and its impact on daily living activities. The Dizziness Handicap Inventory identifies functional, physical and emotional disorders related to balance disturbance. Our objective was to cross-culturally adapt the Peninsular Spanish version of the Dizziness Handicap Inventory for use in Argentina and validate the adapted Argentinian version.
  
  
  METHODS
  We included both healthy subjects and patients with vertigo, dizziness or unsteadiness, aged 18 to 85 years, native Spanish-speaking Argentinians. We introduced linguistic and cultural modifications to the Peninsular Spanish version to obtain the Argentinian one. This version was given twice to 108 patients, 24 to 72 h apart. Internal consistency, test-retest reliability and construct validity were assessed using a visual analogue scale, the Romberg test, the tandem Romberg test and the tandem gait test.
  
  
  RESULTS
  We found high internal consistency (α=0.87) and very high test-retest reliability for the total Dizziness Handicap Inventory score (intraclass correlation coefficient: 0.98) and its subscales. The total Dizziness Handicap Inventory and the functional subscale were found to correlate significantly with the Romberg and tandem Romberg tests. The emotional subscale showed a significant correlation with the Romberg test and the eyes-open tandem Romberg test (P<.05)
  
  
  CONCLUSIONS
  The Argentinian version of the Dizziness Handicap Inventory proved to be a reliable and valid tool to quantify self-perceived handicap resulting from vertigo, dizziness or unsteadiness.
