My office has been critical of the transition when the programming in corrections moved to their new integrated correctional program model. This was done about six years ago or so. It was done for efficiency reasons.
There is some academic literature that is critical of the way the program has rolled out. There used to be separate programs for substance abuse, anger management and family violence. What happened with the introduction of this new model, ICPM, was that they basically threw everything into the same basket, and now you have one program that fits all.
I think it's an approach that may not be yielding the best results, and the academic literature suggests that this may be the case.
