Fifty-nine participants with schizophrenia/schizoaffective disorder and fifty non-clinical controls completed the PSI and a battery of social functioning and social cognition measures.

Pathways to care are causally implicated as a DUP reduction rate-limiting factor. This paper illustrates a balanced care model, wherein resource-intensive community and clinical services are centralized to support a more efficient, standardized, and direct pathway to EIP care; identification of psychosis and psychotic risk states is made by highly-trained diagnosticians; and measurement-based care across the Learning Health System (LHS) is supported by a central assessment team. The Central Assessment of Psychosis Service (CAPS) streamlines core front-end EIP functions across the LHS, thereby alleviating the burden on EIP teams while enhancing access, equity, efficiency, and quality of the initial psychodiagnostic assessment. CAPS represents an innovative application of the balanced care model that preserves the core functions of the EIP team while task sharing or task shifting resource-intensive activities to an academic medical center partner. We review the five core functions of a centralized referral, screening, and assessment service.
