Abstract

BACKGROUND AND OBJECTIVES
Several questionnaires had been developed to assess the handicap due to dizziness. The questionnaires for adults were used and these had been translated into Korean with validity and reliability. However, there is no Korean translation of dizziness inquiry form owing to the little concern of the pediatric dizziness. The objective of this study was to determine the reliability and validity of a Korean Dizziness Handicap Index for Patient Caregivers (KDHI-PC), and revealed the factor analysis of this index. SUBJECTS AND METHOD: We sampled the 24 pediatric patients who had dizziness-related symptoms and visited the hospitals. The patients completed a questionnaire (DHI-PC) that had been translated and reverse translated into Korean. The results of this investigation were analyzed using exploratory factor analysis, Cronbach's α coefficient and internal consistency reliability.
RESULTS
By exploratory factor analysis, KDHI-PC was divided into two scales. This questionnaire showed a good internal consistency (Cronbach's α=0.945). All items had good item-total correlations.
CONCLUSION
The KDHI-PC is a reliable tool for evaluating the dizziness of pediatric patients.
