Abstract

Mental health courts (MHCs) represent a critical diversion mechanism for justice-involved individuals with serious mental illness (SMI), yet substantial variability in eligibility criteria, assessment practices, and program structure limits our understanding of how court-level policies shape participant access and outcomes. This exploratory study provides the first systematic cross-borough comparison of all five New York City MHCs, achieving a 100% response rate across courts. Using an adapted version of a statewide MHC survey instrument, data were collected from court representatives via structured survey administration and supplemental interviews. Findings indicate significant variation across courts in legal and clinical eligibility criteria, assessment personnel and tools, availability of evidence-based interventions, and program capacity, alongside notable convergence in risk assessment practices and clinical gatekeeping standards. A capacity gap analysis revealed that fewer than 12% of estimated felony arrests involving individuals with SMI result in an MHC referral citywide. The near-total absence of post-exit outcome tracking across courts emerged as a substantive finding, underscoring longstanding concerns about the lack of standardized data collection in MHCs nationally. Findings highlight the need for standardized referral criteria, shared outcome data infrastructure, and expanded community resources, particularly housing, to strengthen diversion efforts and improve equity of access for justice-involved individuals with SMI across New York City.
