A team of two female interviewers, two male interview assistants, and one or two additional male observers were stationed in front of targeted drinking establishments to survey individuals about their drinking practices and to collect blood alcohol levels (BALs) using portable breath testers. Of the 176 individuals asked to participate, 156 (88%) consented to be interviewed and 141 (90%) provided breath samples. Of those tested, 40 (29%) were legally intoxicated (BAL greater than or equal to 100 mg/dl) while 68 (49%) registered a BAL of 50 mg/dl or greater. The mean BAL was 72 mg/dl. Individuals reporting that they were going to drive had significantly lower BALs than those planning not to drive. Subjects who thought they were legally intoxicated, on average, had BALs greater than the legal level of intoxication, and BALs significantly greater than those who felt they were not intoxicated. These data suggest that the collection of BAL, in combination with self-reported alcohol data, is an important component of methodologically sound alcohol field research.
由两名女性面试官、两名男性面试助理以及一两名额外的男性观察员组成的团队驻扎在目标饮酒场所前，就饮酒习惯对个人进行调查，并使用便携式呼气测试仪采集血液酒精含量（BAL）。在被邀请参与的176人中，156人（88%）同意接受访谈，141人（90%）提供了呼气样本。在接受测试的人中，40人（29%）达到法定醉酒状态（血液酒精含量大于或等于100毫克/分升），而68人（49%）的血液酒精含量达到50毫克/分升或更高。平均血液酒精含量为72毫克/分升。报告打算开车的人的血液酒精含量显著低于计划不开车的人。认为自己达到法定醉酒状态的受试者，其血液酒精含量平均高于法定醉酒水平，且显著高于那些认为自己未醉酒的人。这些数据表明，采集血液酒精含量并结合自我报告的酒精数据，是方法合理的酒精领域研究的重要组成部分。
