Abstract
ObjectiveTo investigate the reliability and validity of the Chinese Version of Dizziness Handicap Inventory(DHI).
MethodsCross-cultural adaptation of health-related quality of life measures was used for translating the DHI to Chinese version. The DHI contains 7 physical, 9 emotional, and 9 functional questions.The patients scored the DHI straightforward. Then the scores of the total scale and each subscales were calculated and evaluated.Three hundred and sixty-six dizzy patients, 116 males and 250 females, aged from 14 to 79 years, were included in the research and finished the questionnaire of the evaluation.SPSS 13.0 was used for statistical analysis.
ResultsReliability: Cronbach α values for the total and subscale of DHI were 0.751-0.912. The reliability coefficients were 0.877-0.921 (P<0.001). Validity: the correlation coefficients between the total scale and three subscale were 0.815-0.934 (P<0.001). The correlation coefficients of the scores internal the subscale were higher than between the other subscale(r=0.446-0.781). Common factor analysis provides 5 factors. The cumulative variance ratio was 54.5%. The component of each item was over 0.4.
ConclusionsChinese version of DHI has good reliability and validity, which can be used to evaluate the dizzy patients.
