Brief Summary

The goal of this randomized controlled educational study is to learn whether a structured, theory-based program can help reduce drowsy driving among college students (18 years and older) in Nevada. Drowsy driving means driving when you are very sleepy, tired, or struggling to stay alert. It is a serious safety problem because it can slow reaction time, reduce attention, and increase the risk of crashes, injuries, and even deaths. Many college students have irregular sleep schedules due to classes, jobs, late-night studying, and social activities, which can increase tiredness and increase the likelihood of drowsy driving. Research question

  • Complete a short screening to confirm eligibility (for example, being 18+ and having recent experiences of drowsy driving)
  • Provide informed consent before any study activities begin
  • Be randomly assigned to one of the two programs
  • Attend four weekly sessions (about 75 minutes each) over 4 weeks, with a short break and refreshments during sessions
  • Complete surveys at three time points: Baseline (before the program begins), Post-intervention (after week 4), and Follow-up (after two weeks)
  • Answer questions about their drowsy driving behavior and related influences, such as fatigue triggers, barriers to sleep, confidence to avoid driving when sleepy, and supports that make safe choices easier. The study will measure changes in drowsy driving behavior and in MTM-related factors that may explain why these changes occur. For example, the MTM-based program helps students think about the benefits of avoiding drowsy driving (and the risks of continuing it), build behavioral confidence to choose safer options, and identify practical environmental supports (such as a safe place to rest, asking a friend for a ride, using ride-share or public transportation, or adjusting trip timing). It also supports emotional transformation (turning concern into motivation), practice for change (setting goals and tracking progress), and building a supportive social environment (friends and family encouraging safer choices). During the sessions, participants may learn and practice real-world skills such as recognizing early warning signs of sleepiness (heavy eyelids, frequent yawning, drifting lanes, missing exits), using short rest breaks and safe "pull-over" plans, managing schedules to reduce late-night driving, and creating a personal action plan for high-risk situations (after work shifts, long study nights, or long-distance travel). The follow-up survey helps researchers see whether any improvements continue beyond the end of the 4-week program. At the end of the study, results will help colleges, public health professionals, and road safety programs understand what types of education are most effective for preventing drowsy driving in young adults. If the MTM-based program is effective, it could be adapted and used more widely to improve student safety and reduce injuries related to drowsy driving. Participants who complete the final follow-up survey will receive an incentive.

Outcome Measures

Primary Outcomes (3)

  • Change From Baseline in Number of Days of Self-Reported Drowsy Driving in the Past 14 Days

    Self-reported number of days (0-14) during which participants drove while feeling drowsy or fatigued in the previous 14 days. Participants will report the frequency of drowsy driving episodes using a structured survey item assessing behavior over a two-week recall period.

    Baseline (Week 0), immediately post-intervention (Week 4), and follow-up (Week 6)

  • Change From Baseline in Intent to Initiate Reduction of Drowsy Driving (MTM Initiation Scale Score)

    The intent to initiate stopping drowsy driving measured using a single Likert-type item assessing the likelihood of initiating attempts to stop drowsy driving in the coming week. Response options range from 0 (Not at all likely) to 4 (Completely likely); the total score range 0 to 4.

    Baseline (Week 0), immediately post-intervention (Week 4), and follow-up (Week 6)

  • Change From Baseline in Intent to Sustain Reduction of Drowsy Driving (MTM Sustenance Scale Score)

    The Intent to sustain stopping drowsy driving measured using a single Likert-type item assessing the likelihood of stopping drowsy driving from now on. Response options range from 0 (Not at all likely) to 4 (Completely likely); the total score range is 0 to 4.

    Baseline (Week 0), immediately post-intervention (Week 4), and follow-up (Week 6)

Study Arms (2)

MTM-based intervention

EXPERIMENTAL

In this arm, participants will attend a 4-week educational intervention delivered in weekly group sessions (approximately 75 minutes each, including a 5-minute break). The sessions will incorporate experiential learning strategies such as role-plays, video dramatizations, reflective journaling, and peer discussions. Participants will use a provided sleep journal to record nightly sleep duration and any drowsy driving episodes. They will also note emotional or situational triggers related to fatigue and discuss key reflections during weekly group discussions. Session content will address the key constructs of the Multi-Theory Model (MTM) to support behavior change.

Behavioral: MTM Theory based intervention

Standard AAA Knowledge based

ACTIVE COMPARATOR

Participants in the AAA (American Automobile Association) intervention (comparison) group will complete a 5-hour online course focused on drowsy driving prevention. The course will be delivered in four sessions, each approximately 75 minutes in length, matching the session duration of the experimental arm. All sessions will be completed under the supervision of the investigator and CITI-trained study personnel.
