Evaluation and Restoration of Competence to Stand Trial: Intercepting the Forensic System Using the Sequential...

The sequential intercept model (SIM) is used to reduce the penetration of persons with mental illness and substance use disorders in the criminal legal system. Its framework recommends identifying individuals with mental illness at various decision points of criminal case processing, from arrest to return from incarceration, so that they can be diverted toward treatment rather than permeate deeper into the criminal justice system. Communities frequently use the model to augment and inform jail diversion services. Despite the model's widespread adoption, individuals with serious mental illness, intellectual and developmental disabilities, and disorders affecting neurocognition and behavior are often found ineligible for such diversion because their competence to stand trial (CST) warrants evaluation, which effectively pauses their criminal case processes. If found incompetent to stand trial, these people can be ordered for competence restoration treatment, creating a pathway that is different from jail diversion options. Traditional community mental health services and courts await resolution by the "forensic system" before linking these individuals to needed services, and often these linkages are lacking. This review aims to describe and demystify these forensic processes and to highlight the potential use of the SIM to decrease jail stays and maximize community service connections for individuals with some of the most impairing mental health conditions who are involved in the justice system and for whom diversion is a safe option. The authors offer specific examples of intercept opportunities at each step involved in evaluations of CST and in the competence restoration processes.
