Research Overview

Dr. Shrier's research focuses on the link between mental health and risk behavior in adolescents and young adults.
Dr. Shrier has been funded by the National Institutes of Health and other sources to conduct research using momentary assessment methods with mobile devices to study emotional states, social contexts, and health behaviors in vivo. She has developed the MOMENT intervention, which uses smartphones to reduce marijuana use in heavily-using youth, and is currently conducting a randomized controlled trial to test the feasibility and preliminary efficacy of the intervention.

Dr. Shrier and her collaborators created the Safer Sex Intervention, a theory-based individualized intervention to reduce sexual risk behaviors in high-risk adolescent girls. The Safer Sex Intervention is featured in the Centers for Disease Control and Prevention's Compendium of Evidence-Based HIV Prevention Interventions and was selected for replication funding as part of a $75M opportunity through the Office of Adolescent Health, Department of Health and Human Services. Currently, multiple sites across the U.S. are conducting replications of the Safer Sex Intervention.
