Supporting Individuals with IDD in the Criminal Justice System
The Sequential Intercept Model (SIM) is a framework used to identify key points within the criminal justice system where interventions can be applied to prevent individuals, especially those with intellectual and developmental disabilities (IDD), from unnecessarily entering or advancing through the system. By understanding the six intercepts, we can better support individuals with IDD and ensure they receive the care and services they need.
At SpArc, we work to address the unique challenges faced by individuals with IDD at each intercept, offering support and resources to divert them from criminal justice involvement and into community-based programs and services.
Intercept 0: Community Services
Intercept 0 focuses on preventing criminal justice involvement before it begins. This includes ensuring access to essential services such as mental health care, housing, and disability services. SpArc plays a critical role here by connecting individuals with IDD to the supports they need, reducing the likelihood of encounters with law enforcement.
Intercept 1: Law Enforcement/Emergency Services
The first point of contact often involves law enforcement or emergency services. SpArc works to train law enforcement on how to identify and interact with individuals with IDD appropriately. Through our advocacy and support services, we aim to divert individuals from arrest and instead connect them to mental health services or community-based interventions.
Intercept 2: Initial Detention/Initial Court Hearings
When an individual is arrested, they enter the legal system, where decisions are made regarding their detention. SpArc works with public defenders, judges, and prosecutors to advocate for diversion options that consider the unique needs of individuals with IDD. We strive to keep these individuals out of jail and ensure they receive appropriate care.
Intercept 3: Jails/Courts
At this stage, individuals might be detained in jail or involved in court proceedings. SpArc’s team supports mental health courts, specialty courts, and jail diversion programs, helping ensure individuals with IDD are not subjected to unnecessary incarceration. We work to provide alternative solutions that prioritize treatment and rehabilitation over punishment.
Intercept 4: Reentry
Upon release from jail or prison, individuals often face challenges reintegrating into the community. SpArc provides reentry support, including housing assistance, employment services, and connections to mental health care. Our goal is to reduce recidivism by ensuring individuals with IDD have the resources they need to thrive post-release.
Intercept 5: Community Corrections/Community Support
At the final intercept, individuals are often under probation or parole supervision. SpArc assists individuals with IDD in navigating these systems and connects them with community-based services. By offering continued support and monitoring, we work to keep individuals from re-entering the criminal justice system.
