Studies show that people commonly have psychotic symptoms for over a year before receiving treatment. Reducing this duration is critical, because early treatment is strongly associated with better outcomes. The National Academies Forum on Mental Health and Substance Use Disorders hosted a workshop in July 2022 to examine the current evidence on short- and long-term outcomes for people at high risk for psychosis. Speakers explored potential policy solutions and strategies that are most effective for coordinated, early-intervention specialty services. This Proceedings document summarizes workshop discussions.
