Evaluation of an Interactive Mobile Phone-Based Brief Intervention to Reduce Substance-Impaired Driving among Emerging Adults

项目摘要/摘要 吸食大麻后驾驶(DACU)和同时饮酒和吸食大麻后驾驶 严重的公共卫生问题。物质损害驾驶的比率仍然特别高，在 新兴成人和交通事故仍然是与物质相关的死亡的主要原因 人口。短期干预(BIS)已被证明可以减少新兴成年人的酒精和大麻使用， 但到目前为止，还没有研究根据最近的DACU选择新兴成年人并评估 基于移动的物质受损驾驶BI。这项研究将是第一次检查移动电话是否 基于手机的物质受损驾驶BI，包括互动短信，显著减少 在新兴成人药物使用者中的DACU与仅限个性化反馈相比。研究参与者 将有160名新兴成年人(年龄18-25岁)在吸食大麻后和/或同时支持驾驶 在过去的三个月里，大麻和酒精至少使用了三次。在完成基线测量后， 参与者将被随机分配以接受以下任一项：a)物质受损驾驶个性化反馈 或b)物质受损驾驶个性化反馈干预加上交互式文本消息。 参与者将在干预后3个月和6个月完成全面随访。反复采取措施 混合建模分析将用于确定干预是否显著降低DACU 时间到了。该项目有两个具体目标：1)评估基于手机的物质受损驾驶 随机临床试验中的干预，以及2)确定认知因素是否在以前的 研究(如感知危险程度和后果、同伴规范、期望值)调解干预 结果。这项研究具有创新性，因为它利用尖端技术来提供整个干预， 使这项研究能够在短时间内以经济高效的方式接触到大量新兴成年人 举止。这项研究意义重大，因为它将对物质受损驾驶做出重大贡献 通过确定一种干预措施，可以减少这种高危人群中的物质受损驾驶 人口。此外，这项研究将通过以下方式增加快速增长的基于技术的干预文献 包括基于移动的评估、个性化反馈和交互式文本消息。

PROJECT SUMMARY/ABSTRACT Driving after cannabis use (DACU) and driving after simultaneous alcohol and cannabis use represent significant public health concerns. Rates of substance-impaired driving remain especially high among emerging adults, and traffic accidents remain the leading cause of substance-related death among this population. Brief Interventions (BIs) have been shown to reduce alcohol and cannabis use in emerging adults, but to date no study has selected emerging adults on the basis of recent DACU and evaluated the efficacy of a mobile-based substance-impaired driving BI. The present study will be the first to examine whether a mobile phone-based substance-impaired driving BI, including interactive text-messaging, significantly decreases DACU among emerging adult substance users compared to personalized feedback only. Research participants will be 160 emerging adults (ages 18-25) who endorse driving after cannabis use and/or simultaneous cannabis and alcohol use at least three times in the past 3 months. After completing baseline measures, participants will be randomly assigned to receive either: a) substance-impaired driving personalized feedback or b) a substance-impaired driving personalized feedback intervention plus interactive text messages. Participants will complete comprehensive follow-ups 3- and 6-months post-intervention. Repeated measures mixed modeling analyses will be used to determine whether the intervention significantly reduces DACU over time. The project has two specific aims: 1) to evaluate a mobile phone-based substance-impaired driving intervention in a randomized clinical trial, and 2) to determine whether cognitive factors identified in previous research (e.g. perceived dangerousness and consequences, peer norms, expectancies) mediate intervention outcomes. This study is innovative because it utilizes cutting-edge technology to deliver the entire intervention, enabling the study to reach a large number of emerging adults in a short time period in a cost-effective manner. The study is significant because it will contribute substantially to the substance-impaired driving literature by identifying an intervention that can decrease substance-impaired driving among this high-risk population. Additionally, this study will add to the rapidly growing technology-based intervention literature by including mobile-based assessment, personalized feedback, and interactive text-messaging.
