According to an extensive study done by the Michigan Department of Corrections, "program integrity" and "program quality" are crucial to the success of prevention of recidivism. Program integrity measures effectiveness of intervention and program quality assesses how services are made available to the inmates.
There are a number of different programs that have been offered to try to rehabilitate offenders. These programs include, but are not limited to, academic and vocational education and cognitive and behavioral treatment. Despite the 260 treatment programs, this study found that "only 8% of programs were found to be very satisfactory."
