The investigators are developing an interactive, web-based program for youth ages 12-17 focused on the prevention of prescription opioid abuse because to the investigators knowledge, no science-based, interactive program focused on the prevention of prescription opioid abuse among youth exists. This program is grounded in a scientific understanding of risk factors for prescription opioid abuse among youth, employs informational technologies which are effective in promoting relevant knowledge and skills, and presents program content using strategies shown to be highly appealing to adolescents. In the completed Phase 1 of this project, the investigators developed and demonstrated the scientific, technical and commercial merit and feasibility of a prototype of a web-based, prescription opioid abuse prevention program for youth. In Phase 2, the investigators will complete the development of all components of the multimedia, prescription opioid abuse prevention program and conduct a randomized, controlled trial with youth to evaluate the effectiveness of the web-based prevention intervention in increasing knowledge about key issues relevant to prescription opioid abuse among youth, skills acquisition relevant to preventing their misuse, negative attitudes about prescription opioid misuse, and perceived risk associated with their misuse. The investigators will also assess the program's effectiveness in reducing intentions to misuse prescription opioids as well as actual rates of such use. If this tool is shown to be effective, the investigators plan to embed it in a suite of science-based, technology-delivered tools focused on the prevention and treatment of substance use disorders that have been developed and deployed in a wide array of settings by the investigative team.
