Study
Martin (2008) conducted a quasi-experimental design study to test the effectiveness of the Progressive Sanctioning Grid on recidivism of newly released individuals from the Ohio prison system.
The sample of 1,040 was representative of individuals supervised between August and October 2005 (the grid became effective in July 2005). The comparison group of 1,012 was selected using stratified random sampling of first-time, post-release individuals whose supervision started between October and December 2003. Propensity score matching and covariance modeling were used to correct for any observed differences between the two groups. The final matched sample considered of 1,044 individuals, with 522 in each group.
The treatment group was monitored using the progressive sanctioning grid. The comparison group was treated as usual upon reentry into the community. The follow-up period of observation for both samples was the first year of supervision, or until the date of early termination, whichever occurred first.
For the comparison group, the data was coded from narrative, log-style entries. In the data collection for the treatment group, risk scores were extracted from Reentry Accountability Plan (RAP) databases. The major outcomes of interest were felony reoffending and major violation behavior. Felony reoffending was defined as an arrest for committing a new felony crime or having absconded and been declared a violator. The violation measure included misconduct of the highest severity by the sanctions policy, including threats behavior and weapons-related violations. An analysis of covariance was used to analyze the data. No subgroup analyses were conducted.
