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 < 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. FUNDING. This study received no external funding. TRIAL REGISTRATION. Not relevant.
