[Health measurement instruments in patients with vertigo]. / Instrumentos de medida de la salud en pacientes con vértigo.

OBJECTIVE: Compare disability and handicap in patients with dizziness by means of two questionnaires. STUDY DESIGN: Prospective study. PATIENTS: 337 patients seen for non-acute dizziness from peripheral or central origin in a tertiary referral setting. MAIN OUTCOME MEASURES: Spanish version of the Dizziness Handicap Inventory test and UCLA-Dizziness Questionnaire after transcultural adaptation following the method of translation-back-translation. RESULTS: We obtained a good correlation between the frequency of dizzy spells and quality of health as perceived by the patient; also there was good correlation between the intensity of each spell and limitation for performance of daily activities. Quality of life is mainly related to handicap in these patients. CONCLUSION: Vertigo, as a non-fatal health outcome, can be studied following the two main conceptual frameworks of Impairment, Disabilities and Handicap and Health-Related Quality of Life.
