The timeline followback (TLFB) interview is the gold standard for the quantitative assessment of alcohol use. However, self-reported "drinks" can vary in alcohol content. If this variability is not accounted for, it can compromise the reliability and validity of TLFB data. To improve the precision of the TLFB data, we developed a detailed standard operating procedure (SOP) to calculate standard drinks more accurately from participant reports.
For the new SOP, the volume and alcohol content by volume (ABV) of distinct types of alcoholic beverages were determined based on product websites and other reliable sources. Recipes for specific cocktails were constructed based on recipes from bartending education websites. One standard drink was defined as 0.6 oz (14 g) of absolute alcohol. Standard drink totals were contrasted for the new SOP approach and the standard procedure, which generally assumed that one self-reported drink was equivalent to one standard drink.
Relative to the standard TLFB procedure, higher numbers of standard drinks were reported after implementing the TLFB SOP.
Variability in procedures for conversion of self-reported alcohol consumption to standard drinks can confound the interpretation of TLFB data. The use and reporting of a detailed SOP can significantly reduce the potential for such inconsistencies. Detailed and consistent procedures for calculation of standard drinks can enhance the quality of TLFB drinking data.
时间追溯访谈（TLFB）是酒精使用量定量评估的金标准。然而，自我报告的“饮品”酒精含量可能存在差异。如果不考虑这种变异性，可能会损害TLFB数据的可靠性和有效性。为提高TLFB数据的精确性，我们制定了详细的标准操作程序（SOP），以便根据参与者报告更准确地计算标准饮品量。
对于新的SOP，根据产品网站和其他可靠来源确定不同类型酒精饮料的体积和体积酒精含量（ABV）。基于调酒教育网站的配方构建特定鸡尾酒的配方。将一杯标准饮品定义为0.6盎司（14克）纯酒精。对比了新SOP方法和标准程序的标准饮品总量，标准程序通常假定自我报告的一杯饮品等同于一杯标准饮品。
相对于标准TLFB程序，实施TLFB SOP后报告的标准饮品数量更多。
将自我报告的酒精摄入量转换为标准饮品的程序变异性可能会混淆TLFB数据的解释。使用和报告详细的SOP可显著降低此类不一致性的可能性。计算标准饮品的详细且一致的程序可提高TLFB饮酒数据的质量。
