Study Summary

This trial sought to evaluate a novel intervention to reduce aggressive driving.

Who is the study for?
This trial is for adults in Central Ohio with a valid driver's license. It aims to understand aggressive driving, particularly among young drivers. Ages vary by experiment: anyone 18+ for Experiment 1; ages 18-21 for Experiments 2-4 and 6-7; over 21 for Experiment 5. Those prone to motion sickness cannot participate.Check my eligibility
What is being tested?
The study tests how different factors like roadside vegetation, video games, videos, bumper stickers, alcohol-related cues, and music influence aggressive driving behavior using a driving simulation.See study design
What are the potential side effects?
There are no medical side effects as this is not a drug or clinical intervention trial. However, participants sensitive to motion may experience discomfort due to the simulation if they have not been properly screened out.

Experimental Treatment
Group I: Experiment 7Experimental Treatment1 Intervention
Experiment 7 tests whether roadside vegetation can reduce aggression in frustrated drivers. After giving their consent, participants (N=90, n=30 per group) will complete the personality variables (see Experiment 1). Next, they will complete the Enjoyment of Nature Scale (Cheng & Moore, 2012), which contains 7 items (e.g., "I like to see wild flowers in nature" and "Being in the natural environment makes me feel peaceful"; 1=strongly disagree to 5= strongly disagree; Cronbach =.87). Next, participants will be randomly assigned to one of three driving scenarios: (1) roadside vegetation, (2) trash, or (3) control (no roadside vegetation / no trash). After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will be debriefed.
Group II: Experiment 6Experimental Treatment1 Intervention
Experiment 6 will test the effects of music with aggressive versus prosocial lyrics on aggressive driving. The tempo of the music will also be manipulated because it might influence arousal levels. After giving their consent, participants (N=150, n=30 per group) will complete the personal variables (see Experiment 1). Music will be played over the car's sound system. Participants will be randomly assigned to one of five conditions: (1) violent lyrics / upbeat tempo, (2) violent lyrics / calm tempo, (3) prosocial lyrics / upbeat tempo, (4) prosocial lyrics / calm tempo, or (5) no music control. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will be debriefed.
Group III: Experiment 5Experimental Treatment1 Intervention
Experiment 5 tests whether alcohol-related cues can increase aggressive driving. After giving their consent, participants (N=40) will complete the personal variables (see Experiment 1). Next, participants will be randomly assigned to one of two conditions: (1) 12-pack of beer on passenger seat, or (2) 12-pack of sparkling water on passenger seat. Participants will be told that the object on the seat is part of a different experiment that the other experimenter forgot to clean up, which they should ignore it. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will be debriefed.
Group IV: Experiment 4Experimental Treatment1 Intervention
Experiment 4 tests the effects of political bumper stickers on aggressive driving in Republicans versus Democrats. After giving their consent, participants (N=120; n=60 Republicans, n=60 Democrats) will complete the personal variables (see Experiment 1). Some cars in the driving scenario will contain bumper stickers. Experiment 4 has four conditions: (1) Republicans / "Donald Trump for President 2016" stickers, (2) Republicans / "Hillary Clinton for President 2016" stickers, (3) Democrats / "Donald Trump for President 2016" stickers, (4) Democrats / "Hillary Clinton for President 2016" stickers. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will report their attitudes toward Trump and Clinton. A debriefing will follow.
Group V: Experiment 3Experimental Treatment1 Intervention
Experiment 3 tests the effects of racial bumper stickers on black and white participants. After giving their consent, participants (N=120; n=60 black, n=60 white) will complete the personal variables (see Experiment 1), the race IAT, and report their political party. Some cars in the driving scenario will contain bumper stickers. Experiment 3 contains four conditions: (1) white participants / "All Lives Matter" stickers, (2) black participants / "All Lives Matter" stickers, (3) white participants / "Black Lives Matter" stickers, (4) black participants / "Black Lives Matter" stickers. After participants complete the driving scenario, they will complete measures of state and hostile appraisals, and will report their attitudes toward the #BLM and #ALM movements. A debriefing will follow.
Group VI: Experiment 2Experimental Treatment1 Intervention
Experiment 2 tests whether participants actually drive more aggressively after a playing a violent or nonviolent racing video game. After giving their consent, participants (N=60, n=30 each group) will complete the same personal variables as in Experiment 1, and will report the video games they play. Next, participants will be randomly assigned to play one of two types of video games for 20 minutes: (1) violent racing video game, (2) nonviolent racing game, or (3) a neutral game. After participants complete the driving scenario, participants will complete measures of state and hostile appraisals. A debriefing will follow.
Group VII: Experiment 1Experimental Treatment1 Intervention
The purpose of Experiment 1 is to develop a standardized measure of aggressive driving for driver simulation experiments. After giving their consent, participants (N=200) will complete several personal variables (i.e., gender, age, driving experience, driving frequency, trait anger, self-reported aggressive and prosocial driving). Next, participants will watch several short videos of aggressive driving (e.g., speeding, tailgating, driving on shoulder), and road rage (e.g., hitting another vehicle or pedestrian). Participants will indicate whether the driver's behavior was aggressive (yes, no), and will rate how aggressive it was on an 11-point scale (0=not at all aggressive to 10=extremely aggressive). A debriefing will follow.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are there any patient requirements in order to be eligible for this research?

"This study is looking for 830 individuals aged 18-21 who currently exhibit aggression. There are different age requirements for different experiments. For example, Experiment 1 requires participants to be 18 or older, while Experiment 5 requires participants to be 21 or older. Furthermore, all potential participants must have a driver's license and live in Central Ohio."
