ABSTRACT
Throughout this text, we have provided numerous examples of assessment tools, treat-
ment curricula, and the like. And yet, many well-designed interventions in the criminal
justice field have failed, despite being carefully designed and implemented with good
intentions (Gendreau, Goggin, & Smith, 1999; Goggin & Gendreau, 2006). On some level,
this is not surprising given the number of issues that come into play when designing and
implementing correctional treatment programs. However, we know that programs will be
more effective if they are well implemented and are able to maintain fidelity to the
original model. In fact, in a recent meta-analysis, Mark Lipsey et al. (2010) found that
three factors predicted program effectiveness: the type of intervention, the type of
offender (high risk), and the quality of the implementation.
