This article describes the methodology used in the 2007 U.S. National Roadside Survey to estimate the prevalence of alcohol- and drug-impaired driving and alcohol- and drug-involved driving. This study involved randomly stopping drivers at 300 locations across the 48 continental U.S. states at sites selected through a stratified random sampling procedure. Data were collected during a 2-hr Friday daytime session at 60 locations and during 2-hr nighttime weekend periods at 240 locations. Both self-report and biological measures were taken. Biological measures included breath alcohol measurements from 9,413 respondents, oral fluid samples from 7,719 respondents, and blood samples from 3,276 respondents.
本文描述了 2007 年美国全国路边调查中用于估计酒后和毒后驾驶以及涉酒涉毒驾驶流行率的方法。该研究通过分层随机抽样程序在全美 48 个州的 300 个地点随机拦截驾驶员。数据是在 60 个地点的周五白天 2 小时时段和 240 个地点的周末夜间 2 小时时段收集的。采用了自我报告和生物测定两种方法。生物测定包括对 9413 名应答者进行呼气酒精测量,对 7719 名应答者进行口腔液样本采集,对 3276 名应答者进行血液样本采集。
