Today, correctional clinicians are paying increased attention to the integration of science and practice in their work. Consequently, the idea of best practices in corrections is evolving toward using quality research results to inform decisions about interventions and treatment. This article describes two such best practices in intervention with and the treatment of offenders: (1) the use of evidenced-based practices (EBP's) and (2) empirically supported treatments (EST's). EBP's assess the risk and needs of offenders using actuarial means. In addition to these EBP principles, EBP interventions address barriers to treatment. EBP is known to be effective in reducing recidivism. However, there are indications that an EBP approach in not universally applied in correctional settings. EST's are therapies found to be effective for various disorders and symptom amelioration. The use of EST's in the treatment of psychological disorders is an extension of the traditional concept of best practices, in that it does not focus on recidivism prevention. The use of EBP's for recidivism prevention and EST's for symptom amelioration in corrections are two components of best practices that are complimentary to one another, with both emphasizing the use of treatment/intervention models derived from scientific research that are focused on measurable outcomes. 31 Endnotes
