Outcome and process measures used to gage the effectiveness of the Integrated Model in reducing offender recidivism are presented. Each component found within a measure has information regarding its definition, tool/data source, description, frequency, and individual who collects the data. Components are organized into the following measures: recidivism; risk; proxy risk; supervision length; dosage; revocation and violation; program effectiveness; assessment; case plan; workload; violations; organizational climate; and collaboration.
Principles of effective evidence-based intervention are presented. Topics discussed include: evidence-based practice (EBP); term clarification; eight principles for effective interventions -- assess actuarial risk/needs, enhance intrinsic motivation, target interventions, skill train with directed practice, increase positive reinforcement, engage ongoing support in natural communities, measure relevant processes/practices, and provide measurement feedback; components of correctional interventions; implementing EBP principles; applying the principles at the case, agency, and system levels; seven recommended strategies for implementing effective interventions; and levels of research evidence.
