摘要目的 评价中文版酒精使用障碍筛查量表(AUDIT)的信度和效度,为该量表在中国医学生中的推广使用提供科学依据.方法 使用电子问卷,将问卷发给5所医学院校学生,让其按意愿自行填写.了解Cronbach'sα和分半信度评价量表的信度,了解内容效度、结构效度、会聚效度和区别效度评价量表的效度.结果 中文版AUDIT量表总的Cronbach'sα为0.782,分半信度为0.711;危险饮酒、酒精依赖、有害饮酒3个维度的Cronbach'sα分别为0.796、0.561、0.647,分半信度分别为0.794、0.623、0.640.条目水平的内容效度指数(item-level CVI,I-CVI)为0.83 ～ 1.00,平均量表水平的内容效度指数S-CVI (S-CVI/Ave)为0.99,全体一致S-CVI(S-CVI/UA)为0.90,内容效度比为0.80～ 1.00.探索性因子分析结果显示,中文版AUDIT量表符合预设的3个维度结构,累计方差贡献率为61.175％;量表的会聚效度与区别效度定标试验成功率均为100％.结论 中文版AUDIT量表在中国医学生中具有较好的信度和效度,值得推广使用.

abstractsObjective To assess the reliability and validity of the Chinese version on Alcohol Use Disorders Identification Test (AUDIT) among medical students in China and to provide correct way of application on the recommended scales.Methods An E-questionnaire was developed and sent to medical students in five different colleges.Students were all active volunteers to accept the testings.Cronbach's α and split-half reliability were calculated to evaluate the reliability of AUDIT while content,contract,discriminant and convergent validity were performed to measure the validity of the scales.Results The overall Cronbach's α of AUDIT was 0.782 and the split-half reliability was 0.711.Data showed that the domain Cronbach's α and split-half reliability were 0.796 and 0.794 for hazardous alcohol use,0.561 and 0.623 for dependence symptoms,and 0.647 and 0.640 for harmful alcohol use.Results also showed that the content validity index on the levels of items I-CVI)were from 0.83 to 1.00,the content validity index of scale level (S-CVI/UA) was 0.90,content validity index of average scale level (S-CVI/Ave) was 0.99 and the content validity ratios (CVR) were from 0.80 to 1.00.The simplified version of AUDIT supported a presupposed three-factor structure which could explain 61.175％ of the total variance revealed through exploratory factor analysis.AUDIT semed to have good convergent and discriminant validity,with the success rate of calibration experiment as 100％.Conclusion AUDIT showed good reliability and validity among medical students in China thus worth for promotion on its use.
