Interventions and Outcome Measures

Arms

active comparator: Enhanced Usual Care

When the online consent/assent form is completed, the teen will be sent a personalized link to complete their baseline survey. Upon survey completion, the teen will receive a link that has their electronic gift card payment, and the case manager will be notified that a particular ID has completed the survey. The case manager will be informed by study staff whether to schedule that ID for enhanced usual care (EUC) or the Chat intervention. If they are randomized as EUC, the informational brochure for the EUC will be handed to the teen during the visit or securely emailed to them. Whether the teen completes EUC or Chat, every teen will be followed by the RAND Survey Research Group to complete their paid follow-up web-based surveys based on timing of completion of their baseline survey.
