Research Studies

North American Prodrome Longitudinal Study (NAPLS)

Mental health problems affect many individuals and often begin to develop in adolescence or young adulthood. The goal of the NAPLS study is to improve the ability to identify youth who are at risk for developing psychosis and better understand why some young people develop psychosis and others do not. This study funded by the National Institute of Mental Health (NIMH) and is part of a group of prodromal research sites across North America.

The NAPLS Project is recruiting young people in the San Francisco Bay Area who are concerned about the possibility of developing psychosis. Your involvement may help us to learn how certain mental health problems begin, how to predict who may be most at risk, and who is most likely to improve over time.

People experiencing the following symptoms may be at increased risk for developing an illness like psychosis:
