The Sequential Intercept Model (SIM) is a conceptual model that informs community-based responses to the involvement of people with mental and substance use disorders in the criminal justice system. This microsite contains resources and tools for communities that have had or are interested in bringing a SIM Mapping Workshop to their jurisdiction.

The SIM is composed of six intercepts:

  1. Intercept 0: Community Services
  2. Intercept 1: Law Enforcement
  3. Intercept 2: Initial Detention/Initial Court Hearings
  4. Intercept 3: Jails/Courts
  5. Intercept 4: Reentry
  6. Intercept 5: Community Corrections

The microsite is broken down into five sections:

  1. History and impact of the SIM
  2. Best practices at each intercept
  3. Best practices across the intercepts
  4. The SIM as a strategic planning tool
  5. About PRA

Also included in the microsite are downloads of the SIM tri-fold brochure and one-pager.

The SIM was developed in the early 2000s by Mark Munetz, M.D., and Patricia A. Griffin, Ph.D., along with Henry J. Steadman, Ph.D., of PRA. Dr. Steadman first conceptualized the linear model in 2004 through a Small Business Innovative Research grant from the National Institute of Mental Health after several years of refinement and testing. PRA published the model in 2005. Since its development and publication, the SIM has been well established as a strategic planning tool.
