The National Institute of Mental Health Collaborative Psychiatric Epidemiology Surveys (CPES) provides data on the distributions, correlates, and risk factors of mental disorders among the general population, with special emphasis on minority groups to permit the investigation of cultural and ethnic influences on mental health. This project joins together three nationally representative surveys: the National Comorbidity Survey Replication (NCS-R), the National Survey of American Life (NSAL), and the National Latino and Asian American Study (NLAAS).
