Dr. C. Hendricks Brown’s work has focused on the prevention of serious mental disorders such as schizophrenia, and also the prevention of suicide. He now co-directs a randomized trial of 32 schools to evaluate the use of a gatekeeper training program to prevent suicide in middle and high schools, a randomized trial of the Sources of Strength suicide prevention program being conducted in three states, a randomized trial of a first-grade classroom behavior and curriculum intervention to prevent drug abuse, and a randomized trial of 40 counties in California to test the dissemination of an evidence-based foster care program. He co-directs a NIDA funded study to examine variation in preventive effects within and across sites from the United States and the European Union. He also has funding from NIMH to evaluate the impact of antidepressants on suicide using multiple datasets.
