Youth who provide appropriate consents/assents will be emailed a unique study identification (ID) and temporary password to use on the study's secure website. During the initial login, participants will be required to change their password. Participants will be invited to complete baseline assessments online. As a further validity check, participants will be asked for their Date of Birth twice at baseline. If an individual provides discrepant dates, s/he will not be invited to move forward with randomization but will be referred to the Drug Enforcement Administration's website (JustThinkTwice.gov).
