The importance of staff practice in delivering effective correctional treatment: a meta-analytic review of core correctional practice.

Several meta-analyses have rendered strong support for the clinically relevant and psychologically informed principles of human service, risk, need, and general responsivity. However, each of these reviews has focused on specific program components and not on the characteristics of the staff or the specific techniques used to deliver the program. This meta-analytic review examines the role of core correctional practices in reducing recidivism and provides strong preliminary evidence regarding their effectiveness. Staff characteristics and training in core skills must be addressed to ensure the maximum therapeutic impact of correctional treatment programs.
