Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The main aim of this formative study is to test and iteratively refine a new mobile phone app, which delivers assessments and tailored intervention content. The study will use social media advertisements to recruit a total of 40 youth between the ages of 16-24 years. Those screening positive for past-month binge drinking or marijuana use will be invited to complete a baseline survey, download and use the app for 30 days, and complete a follow-up survey about the app functionality, design and content, and preliminary outcomes (intentions and importance of reducing use).
