Racial-ethnic disparities in empirically-derived subtypes of subclinical psychosis among a U.S. sample of youths.

ABSTRACT:

Introduction

Racial-ethnic minority status is a consistent risk factor for schizophrenia, with associations extending to bipolar disorder and subthreshold psychotic experiences.
