The Sequential Intercept Model

The Sequential Intercept Model (SIM) was developed over several years in the early 2000s by Mark Munetz, MD and Patricia A. Griffin, PhD, along with Henry J. Steadman, PhD, of Policy Research Associates, Inc. The SIM was developed as a conceptual model to inform community-based responses to the involvement of people with mental and substance use disorders in the criminal justice system.

Since its development, the use of the SIM as a strategic planning tool has grown tremendously. In the 21st Century Cures Act, the 114th Congress of the United States of America identified the SIM, specifically the mapping workshop, as a means for promoting community-based strategies to reduce the justice system involvement of people with mental disorders.(5) SAMHSA has supported community-based strategies to improve public health and public safety outcomes for justice-involved people with mental and substance use disorders through SIM Mapping Workshop national solicitations and by providing SIM workshops as technical assistance to its criminal justice and behavioral health grant programs. In addition, the Bureau of Justice Assistance has supported the SIM Mapping Workshop by including it as a priority for the Justice and Mental Health Collaboration Program grants.
