Clinical trials

LaunchPad is an online substance use prevention program for high school seniors. The program is designed to help seniors develop skills and make informed decisions as they transition from high school to young adulthood. The purpose of this clinical trial is to learn whether individual LaunchPad lessons improve the specific attitudes, intentions, and skills they are designed to address. For example, researchers will examine whether the stress management lesson increases students' intentions to use healthy ways of managing stress. The main question this study aims to answer is: Does each individual LaunchPad lesson improve the specific outcomes it was designed to address? Researchers will compare students who receive a particular lesson with students who do not receive that lesson to determine whether the lesson changes the intended outcome. Participants will: * Complete a brief baseline survey * Complete two introductory online lessons * Complete one or more randomly assigned LaunchPad lessons * Complete a brief follow-up survey All surveys and lessons will be completed online.
