To study the psychometric properties of a modified Alcohol Use Disorders Identification Test in the multilingual context of Switzerland.
Data were obtained from the most extensive health survey to date in Switzerland, with a response rate of 69%. Seven core items of AUDIT were used. The first two items of AUDIT (frequency of drinking, quantity of drinking) were not used in their original form, but reconstructed from a quantity-frequency instrument (QF) measuring alcohol consumption, and categorized according to the AUDIT. The third AUDIT item (frequency of binge drinking) was similarly not used in its original form, but 8+ drinks instead of 6+ drinks was used. All 10 items of the modified AUDIT were completed by 10321 subjects - 6677 in the German-speaking region and 3644 in the Latin-language (French, Italian) regions. The dimensionality of the modified AUDIT was modelled by confirmatory factor analysis. The contribution of each item to the total modified AUDIT score was investigated by the prevalence of positively screened subjects when items were deleted, and factor loadings of the unidimensional model.
In Switzerland the modified AUDIT fitted neither a unidimensional nor the hypothesized tri-dimensional model. Consumption items, especially frequency of drinking, showed almost no correlation with items measuring alcohol-related problems, but the latent constructs 'harmful drinking' and 'alcohol dependence' were highly correlated, indicating a shared underlying factor. Frequency of drinking was the item that most influenced whether an individual screened positively or not. Except for the correlation of frequency and binge drinking, results were almost identical for both linguistic regions.
The current form of the modified AUDIT may have to be changed for screening in Switzerland, as the study raised questions about the suitability of the frequency-of-drinking item as an indicator of a screening device for alcohol-related problems in this country.
在瑞士多语言环境下研究改良版酒精使用障碍识别测试的心理测量特性。
数据取自瑞士迄今为止规模最大的健康调查，应答率为69%。使用了酒精使用障碍识别测试（AUDIT）的七个核心项目。AUDIT的前两个项目（饮酒频率、饮酒量）并非采用其原始形式，而是根据一个测量酒精消费的量频工具（QF）重新构建，并按照AUDIT进行分类。AUDIT的第三个项目（暴饮频率）同样未采用其原始形式，而是使用8杯及以上饮酒量替代了6杯及以上。10321名受试者完成了改良版AUDIT的所有10个项目，其中德语区6677人，拉丁语言区（法语、意大利语）3644人。通过验证性因素分析对改良版AUDIT的维度进行建模。通过删除项目时阳性筛查受试者的患病率以及单维模型的因素负荷，研究每个项目对改良版AUDIT总分的贡献。
在瑞士，改良版AUDIT既不符合单维模型，也不符合假设的三维模型。消费项目，尤其是饮酒频率，与测量酒精相关问题的项目几乎没有相关性，但潜在结构“有害饮酒”和“酒精依赖”高度相关，表明存在一个共同的潜在因素。饮酒频率是对个体是否筛查为阳性影响最大的项目。除了饮酒频率与暴饮的相关性外，两个语言区的结果几乎相同。
在瑞士进行筛查时，可能需要改变改良版AUDIT的当前形式，因为该研究对饮酒频率项目作为该国酒精相关问题筛查工具指标的适用性提出了质疑。
