摘　　要：目的 探讨头晕评价量表（dizziness handicap inventory,DHI）中文版的信度和效度特征.方法 采用跨文化翻译法将DHI量表翻译成中文版,量表包含有躯体（physical）、情感（emotional）和功能（functional）三个子维度,每个子维度包含7～9个题目,共25个题目.受试者对每个问题进行打分,按照评分标准将所得分数相加,分别计算三个子维度得分和总分.共有366例确诊头晕患者（男116例,女250例;年龄14～79岁）完成DHI中文版量表测试.使用SPSS 13.0软件对测试数据进行统计学分析,评价量表的信度和效度.结果 信度检验：总量表及三个子维度评分的内部一致性检验,Cronbachα系数为0.751 ～0.912,重测信度系数为0.877～0.921（P＜0.001）;效度检验：结构效度检验显示三个子维度与总表之间的相关度为0.815 ～0.934（P＜0.001）;25个题目在所属三个子维度内部的r值为0.446 ～0.781,明显高于与其他子维度之间的相关性;主成分因子分析：特征根大于1的公因子5个,累计贡献率54.515％,各条目负荷大于0.4.结论 DHI量表中文版具有良好的信度和效度,可以初步用来作为头晕患者自我评估的工具.Objective To investigate the reliability and validity of the Chinese Version of Dizziness Handicap Inventory（DHI）.Methods Cross-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.Results Reliability：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.Conclusions Chinese version of DHI has good reliability and validity,which can be used to evaluate the dizzy patients.
