After 9/11, mental health workers in New York City found themselves overwhelmed with requests to provide treatment to kids and their families. In response, clinical psychologist Laura Murray and her colleagues developed the Common Elements Treatment Approach, or CETA, which helps providers address multiple problems and symptoms using a customized plan of evidence-based therapies. Dr. Murray talks with Stephanie Desmon about the program's applications in conflict zones like Ukraine, and its promise in bolstering mental health programs in the US.
