Official title

Evaluation of an Interactive Text-Message Based Brief Intervention to Reduce Substance-Impaired Driving Among College Students

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Substance-Impaired Driving among college students remains a significant public health concern and may be the single riskiest substance-related outcome among young adults. Brief Interventions (BIs) have been shown to reduce alcohol-impaired driving among college students, but are not often implemented - despite their demonstrated efficacy - because it is not economically feasible for universities to hire and train staff to deliver in-person BIs to all college substance users. Very few college students seek out substance prevention or treatment services available on campus or in the surrounding community. Innovative ways of delivering BIs to this at-risk population in a manner that is both effective and economically feasible have to be developed. The present study will be the first to examine whether a text-messaging-based substance-impaired driving BI significantly decreases substance-impaired driving among colleges substance users compared to an informational control. Participants will be 150 college students who endorse driving after substance use (alcohol, drugs, and/or combined alcohol/drugs) at least twice in the past 3 months. After completing baseline measures, participants will be randomly assigned to receive either: a) substance use information, b) a substance-impaired driving personalized feedback intervention, or c) a substance-impaired driving personalized feedback intervention plus interactive text messages. Participants will complete outcome measures 3, 6, and 12 months post-intervention. Repeated measures mixed modeling analyses will be used to determine whether the intervention significantly reduces substance-impaired driving over time. The project has two specific aims: 1) to evaluate a text based substance-impaired driving intervention in a randomized clinical trial, and 2) to determine whether the use of interactive text-messages sustains intervention effects over time. This study is innovative because it utilizes cutting-edge technology to deliver the entire intervention, enabling the study to reach a large number of students in a short time period at a low cost. 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 newly emerging technology-based intervention literature.
