Motivations, Attitudes, and Perceptions Study

The goal of this clinical trial is to compare the impact of providing participants with 1. A recently developed protocol for motivating bystanders to intervene to help others who are in sexual risk situations (Motivate-the-Bystander) alone 2. Motivate-the-Bystander with an alcohol component focused on reducing drinking behaviors (Motivate-the-Bystander+Alcohol) 3. A control condition focused on reducing stress The main questions it aims to answer are: * Is Motivate-the-Bystander more effective than the attention control for increasing bystander behaviors? * Is Motivate-the-Bystander+Alcohol more effective than MTB alone for increasing bystander behaviors? * Is Motivate-the-Bystander+Alcohol more effective than Motivate-the-Bystander alone for decreasing alcohol use during bystander intervention opportunities? Participants will: * Complete online measures (e.g., self-reported bystander behaviors, past bystander training, history of bystander intervention attempts, sexual experiences, drinking behaviors, and other substance use behaviors) * Complete either MTB, MTB+ALC, or the attention control condition online * Complete the virtual reality simulation in the lab * Complete electronic daily diary follow-up surveys about alcohol use and bystander intervention
