To describe inconsistencies in reporting past-year drinking status and heavy drinking occasions (HDOs) on single questions from two different instruments, and to identify associated characteristics and impacts.
We compared computer-presented Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) with categorical response options, and mental health interview (MHI) with open-ended consumption questions, completed on the same day. Participants were 464 men and 459 women aged 38 (91.7% of surviving birth cohort members). Differences in dichotomous single-item measures of abstention and HDO frequency, associations of inconsistent reporting with sex, socioeconomic status (SES) and survey order, and impacts of instrument choice on associations of alcohol with sex and SES were examined.
The AUDIT-C drinking frequency question estimated higher past-year abstention prevalence (AUDIT = 7.6%, MHI = 5.4%), with one-third of AUDIT-C abstainers being MHI drinkers. Only AUDIT-C produced significant sex differences in abstainer prevalence. Inconsistencies in HDO classifications were bidirectional, but with fewer HDOs reported on the MHI than AUDIT-C question. Lower SES was associated with inconsistency in abstention and weekly+ HDOs. Abstention and higher HDO frequency were associated with lower SES overall, but sex-specific associations differed by instrument.
In this context, data collection method affected findings, with inconsistencies in abstention reports having most impact. Future studies should: (a) confirm self-reported abstention; (b) consider piloting data collection methods in target populations; (c) expect impacts of sex and SES on measurements and analyses.
描述在使用两种不同工具中的单个问题报告过去一年饮酒状况和重度饮酒场合（HDOs）时存在的不一致性，并确定相关特征和影响。
我们比较了当天完成的、带有分类回答选项的计算机呈现的酒精使用障碍识别测试-消费版（AUDIT-C），以及带有开放式消费问题的心理健康访谈（MHI）。参与者为464名男性和459名女性，年龄38岁（占存活出生队列成员的91.7%）。研究了在戒酒和HDO频率的二分单项测量上的差异、不一致报告与性别、社会经济地位（SES）和调查顺序的关联，以及工具选择对酒精与性别和SES关联的影响。
AUDIT-C饮酒频率问题估计的过去一年戒酒患病率更高（AUDIT = 7.6%，MHI = 5.4%），AUDIT-C中三分之一的戒酒者在MHI中被列为饮酒者。只有AUDIT-C在戒酒者患病率上产生了显著的性别差异。HDO分类中的不一致是双向的，但MHI报告的HDO比AUDIT-C问题少。较低的SES与戒酒和每周及以上HDOs的不一致相关。总体而言，戒酒和较高的HDO频率与较低的SES相关，但特定性别的关联因工具而异。
在这种情况下，数据收集方法影响了研究结果，戒酒报告中的不一致影响最大。未来的研究应该：（a）确认自我报告的戒酒情况；（b）考虑在目标人群中试点数据收集方法；（c）预期性别和SES对测量和分析的影响。
