Given the pervasive misconceptions that many youth have in their understanding of the risks associated with prescription opioid misuse, the investigators will primarily focus analyses on knowledge about prescription opioid misuse as well as measures that are highly predictive of future use (attitudes, intentions, skills and perceived risk). Actual rates of use will be a secondary focus, because of the planned evaluation window and because this is a primary prevention trial and is not primarily focused on recruiting and promoting behavior change among a select sample of youth who are misusing prescription opioids at baseline. The investigators will be able to assess if the web-based program results in lower rates of use up to 6 months post-intervention.
