Incidence of first-episode psychosis was higher among individuals in ethnic minority groups, lower socioeconomic groups and those who lived in more urban or deprived neighborhoods, suggesting potential target areas for intervention services.
“Unfortunately, psychosis epidemiology is predominantly informed by an older literature, conducted prior to the widespread introduction of these services, almost exclusively based in urban settings. This research has revealed important heterogeneity in incidence by person and place, generating new directions for etiological research. However, national implementation efforts being developed in countries such as Denmark, Australia, and Canada, and currently undergoing revision in the United Kingdom, require accurate, relevant estimates about the epidemiology of psychotic disorders in populations served by early intervention psychosis services,” James B. Kirkbride, PhD, of University College London, and colleagues wrote.
“Such data will also be critical in countries such as the United States, where early intervention initiatives are gaining traction but where little recent epidemiological data exist to inform service provision.”
