    Welcome to the Lab for Youth Mental Health, led by Professor John Weisz.

  • Our Research

    Our research bridges the gap between clinical science and practice to improve youth mental health care.



    We have implemented and tested a modular approach to youth psychotherapy in communities and schools across the globe.

  • Meta-Analysis

    We conduct meta-analyses of psychotherapy research to characterize the state of our field and improve research and practice.


    We have developed an efficient, principle-guided treatment targeting an array of youth mental health problems.

  • FIRST Project Manual and Study Design


    We are now using FIRST in an NIMH-funded multisite clinical trial in Massachusetts and Texas.

  • Brief Digital Interventions

    Brief Digital Interventions
