Using data from the NIMH-sponsored RAISE-ETP trial, this study examines socioeconomic barriers to the effec- tive provision of psychiatric care. RAISE investigators found modest benefits of an early-intervention program for patients with first-episode psychosis. Our preliminary analysis suggests a large and statistically significant gap in which only high-SES patients benefitted from the intervention. We will examine possible explanations for this pattern, including SES differences in initial mental health, stigma, treatment adherence, cognition, substance abuse, and economic empowerment. Finally we will quantify the contribution of this pattern for the SES gap in mental health. This inquiry is distinct from any analysis that the RAISE investigators have proposed or carried out.
