Risk for Alcohol Impaired Driving: From the Laboratory to the Natural Environment

项目摘要 尽管以前在减少酒精损害驾驶（AID）方面取得了成功，但与酒精有关的 自1990年代以来，机动车撞车事故没有显著减少。开发新型 要取得进一步进展，可能需要采取预防/干预办法。基础上 最初项目的实验室结果（急性酒精对冲动性和风险的影响， 饮酒和驾驶），拟议的项目旨在将这项工作从实验室带到 在自然的饮用环境中做出援助决定。参与者将完成 实验室酒精管理会议，随后是6周的多方法门诊 考核门诊评估部分将包括参与者报告， 智能手机，使用BACtrack生物传感器的经皮酒精浓度（TAC），以及 智能手机GPS/加速度计被动收集的位置和移动数据。的 这些方法的组合将允许主观（例如，感知 中毒）和客观（例如，TAC，计算的饮用位置）数据 插曲。该项目的目标1是测试实验室措施作为艾滋病的预期预测因素， 研究事件层面对具体AID决策的影响。 拟议项目的目标2是测试减少艾滋病的新干预措施的潜力 使用移动的技术。受试者将被随机分配到一个完整的门诊 评估或最小评估控制条件。引入机管局的时间， 也可以在完全动态评估条件下进行操作。这种设计将使我们能够 测试引入动态评估是否会改变AID行为， 以及一旦停止门诊评估，这些变化是否持续。变化 修订后的申请旨在确保实现这两个研究目标。如果 目的2已经实现，门诊评估改变了AID行为， 最小评估控制条件和引入前的完全评估条件 有足够的样本量和功效来检验目标1假设。

Project Summary Despite previous success in reducing alcohol impaired driving (AID), rates of alcohol-related motor vehicle crashes have not decreased significantly since the 1990s. Developing novel approaches to prevention/intervention is likely required to produce further progress. Building on laboratory findings from the original project (Acute Alcohol Effects on Impulsivity and Risk for Drinking and Driving), the proposed project is designed to bring this work out of the lab and into the natural drinking environment in which AID decisions are made. Participants will complete a laboratory alcohol administration session followed by six weeks of multi-method ambulatory assessment. The ambulatory assessment component will include participant report via smartphone, transdermal alcohol concentration (TAC) using the BACtrack biosensor, and location and movement data passively collected by the smartphone GPS/accelerometer. The combination of these methods will allow for the integration of subjective (e.g., perceived intoxication) and objective (e.g., TAC, calculated drinking location) data for each drinking episode. Aim 1 of the project is to test laboratory measures as prospective predictors of AID and examine the role of event-level influences on specific AID decisions. Aim 2 of the proposed project is to test the potential for a novel intervention to reduce AID using mobile technology. Participants will be randomly assigned to either a full ambulatory assessment or a minimal assessment control condition. The timing of the introduction of AA will also be manipulated within the full ambulatory assessment condition. This design will allow us to test whether the introduction of ambulatory assessment produces changes in AID behavior, as well as whether such changes persist once ambulatory assessment is discontinued. Changes made to the revised application are aimed at ensuring the achievement of both study aims. If Aim 2 is achieved and ambulatory assessment alters AID behavior, the combination of the minimal assessment control condition and the full assessment condition prior to the introduction of ambulatory assessment has sufficient sample size and power to test Aim 1 hypotheses.
