IntroductionCommunity corrections essentially refers to the sanctions that are usually imposed on both adults and juveniles sentenced by the court 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 except prisons (Gendreau & Goggin, 1996). Over the past several decades, researchers have struggled to advance community corrections through the use of effective intervention principles. In fact, these community corrections triggered 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 necessity principle, the of treatment and the principle of fidelity (Anstiss, 2013). These principles have common characteristics that help reduce recidivism based on meta-results and meta-analyses obtained from hundreds of studies. It is crucial to highlight the fact that the “what works” movement has seen tremendous success in the assessment and rehabilitation of criminals in almost all criminal justice systems around the world, especially in the United States (Cullen & Gendreau, 2011). This document is an analysis of the above principles of effective intervention, in particular their implications and the effectiveness of each principle.i) The risk principle According to Lovins et al (2007), the risk principle is the first general principle extremely well supported in a good amount of research literature focused on community corrections. It is usually based on the fact that a criminal's behavior can be predicted, and therefore this explains why this principle is... in the center of the paper... example, a functional family therapy based on the most compatible The model can provide the best percentages successful in terms of reducing reoffending when delivered consistently by well-trained professionals. Fundamentally, this principle is based on the idea that an intervention program must adhere to the best features aimed at reducing recidivism rates; the integrity of an intervention program should be maintained when it comes to providing community correctional services (Gendreau & Goggin, 1996). Conclusion It is quite clear that it can hardly be said which of these principles of effective intervention is more effective or important than the other when it comes to community corrections. However, the best results can only be achieved if these principles are applied together; reinforcing one principle with others (Anstiss, 2013; Cullen & Gendreau, 2011).
