In light of this dire situation, the team of Prof. Lydia A. Shrier at Boston Children’s Hospital, Massachusetts has developed an interventional program called MOMENT (Momentary Self-Monitoring and Feedback + Motivational Enhancement Therapy), which combines brief motivational enhancement therapy provided in clinic followed by ecological momentary interventions delivered via mobile technology aiming to reduce marijuana use among this vulnerable group of people. mHealth is pleased this time to interview Prof. Shrier who will share with us more about this interventional program.
