IntroductionEssentially, community corrections are assigned to the sanctions that are usually imposed on adults and juveniles convicted by the court in order to reduce the frequency of recidivism. Unlike other forms of sentencing, community corrections can be implemented in a community setting or in any other residential setting, other than prisons (Gendreau & Goggin, 1996). Over the past several decades, researchers have worked to advance community corrections through the use of effective intervention principles. In fact, these community corrections sparked the "what works" movement, a movement formalized in 1990. There are four general principles of effective intervention on which the movement is currently based: the risk principle, the criminogenic need principle, principle of treatment and the principle of fidelity (Anstiss, 2013). These principles have common features that help reduce recidivism based on meta-findings and meta-analyses obtained from hundreds of studies. It is imperative to highlight the fact that the “what works” movement has recorded massive success based on the assessment and rehabilitation of criminals in almost every criminal justice system around the world, particularly in the United States. (Cullen and Gendreau, 2011). This article is an analysis of the principles of effective intervention mentioned above, particularly their implications and the effectiveness of each principle.i) The risk principleAccording to Lovins et.al (2007), the risk principle is the first principle extremely well supported general. in many research papers focused on community corrections. It is generally based on the fact that the behavior of a criminal can be predicted, and this therefore explains why this principle is...... middle of paper ...... example, functional family therapy based on most compatible methods This model can provide the best success rates in reducing recidivism when applied consistently by well-trained professionals. Fundamentally, this principle is based on the idea that an intervention program must adhere to the best features intended to decrease recidivism rates; the integrity of an intervention program must be maintained when it comes to the delivery of community corrections (Gendreau & Goggin, 1996). Conclusion Obviously, it is difficult to say which of these principles of effective intervention are more effective or more important than the other when it comes to community corrections. However, the best results can only be achieved if these principles are applied together; by reinforcing one principle with others (Anstiss, 2013; Cullen & Gendreau, 2011).
