The Danish version of the Dizziness Handicap Inventory - translation and validation.
Introduction: The Dizziness Handicap Inventory (DHI) is a widely used patient-reported outcome measure assessing the impact of dizziness on daily life. A Danish version (DHI-DK) was developed to facilitate its use in Danish-speaking populations.
Methods: The DHI was translated into Danish following standard cross-cultural adaptation procedures. The psychometric properties of the DHI-DK were evaluated in a sample of 100 patients with dizziness. Internal consistency was assessed using Cronbach's alpha, test-retest reliability with intraclass correlation coefficients (ICCs), and construct validity through correlations with the visual analogue scale (VAS).
Results: The DHI-DK demonstrated high internal consistency (Cronbach's alpha = 0.88) and excellent test-retest reliability (ICC = 0.95). A strong correlation was observed between DHI-DK and VAS scores (r = 0.60, p less-than 0.001), supporting construct validity.
Conclusions: The DHI-DK is a reliable and valid instrument for assessing the self-perceived handicap due to dizziness in Danish-speaking patients. It is suitable for use in both clinical practice and research settings.
