This article examines theoretical strengths and weaknesses of the Risk–Need–Responsivity (RNR) model of offender rehabilitation. It briefly discusses the nature of rehabilitation theories and their core components and reviews the three source theories associated with the RNR Model. Reconstructs the RNR model in light of this analysis, essentially arguing that there are at least three components to any rehabilitation theory: primary aims, values and principles; etiological and methodological assumptions; and practice implications. Evaluates the theoretical and empirical adequacy of the RNR model in this light and conclude with comments on the policy, research, and clinical implications of this evaluation (and reconstruction) of this mportant rehabilitation model.
