My main research interests are in the development of therapeutic approaches to prevent psychosis and enhance functioning and protective factors (coping, supportive family environment) among youth at clinical high risk for psychosis. Recently, colleagues and I completed a randomized clinical trial that found that an intervention that provided 18 sessions of family focused therapy (FFT) and included psycho-education, communication and problem solving training was associated with greater reductions in positive symptoms of psychosis and a more supportive family environment than was an intervention that included 3 sessions of family psychoeducation. We are currently conducting a multisite dissemination study in Los Angeles County to evaluate whether therapists at community mental health centers can be trained to provide family focused therapy with high levels of adherence and competence, and whether administration of FFT to a diverse community population is tolerable to families and associated with improvements in symptoms and functioning for youths at high risk for psychosis or experiencing a first episode of psychosis and their families. In addition, we are studying mechanisms that may account for improved outcomes. I am also quite interested in teaching students how to conduct evidence based assessment and treatment with a variety of patient populations.
