Jennifer Skeem (UCB) and Susan Turner (UCI) were awarded $1.6M by the Laura and John Arnold Foundation (LJAF) to conduct a five-study that will advance policy for justice-involved people with mental illness. In this randomized controlled trial, we will test whether and how Interventions, a cognitive-behavioral group treatment program, reduces recidivism for this population, compared to existing services in a mental health court or a day reporting center.
