The U.S. faces an unprecedented behavioral health crisis among youth and adults. As a trusted partner to the federal, state, and local sectors, Abt informs public policy on behavioral health through a comprehensive suite of approaches. We use systems change thinking, evaluation design and implementation, scientific evidence, health communications, capacity-building, and collaboration to heal the whole person. We also promote behavioral health equity by addressing social determinants of health, including insurance access, stable employment, stable housing, education, and culturally sensitive care. Our experts bring their backgrounds in social work, clinical psychology, public health, and sociology to offer integrated prevention, treatment, and intervention.
