The concept of jail diversion and its implementation has evolved quickly in recent years. Currently, the literature suggests that the stage of jail diversion programs most in need of scrutiny is the point at which the offender is diagnosed as suffering from mental illness and/or co-occurring disorders. The stages prior to diagnoses are mostly settled. Further assessment beyond mental illness/co-occurring disorders is necessary. Specifically, there is a need to assess the offender’s openness/resistance to treatment. This is a critical decision point that drives future actions and placement of the offender. Not assessing this construct allows chance to immediately enter the equation negatively impacting program results. The next decision point is the appropriate matching of offenders with available mental health services. There is the need to ensure that the therapeutic alliance has been established and that it continues to flourish throughout the duration of provided services. Finally, there is the need to ensure that a quality mental health service is being provided. This is primarily accomplished through the intense oversight of knowledgeable and informed caseworkers. The purpose of this paper is to highlight three critical components, noted above, related to the success of jail diversion programs: (1) offenders must be psychometrically assessed for resistance to treatment; (2) there must be a proper match between offender and service provider; and (3) quality mental health services must include treatment specialists who are routinely involved from intake all the way through program completion.
