Rehabilitative and reintegrative penalties are intended to reduce reoffending by reducing an offender’s wish or desire, need, and/or disposition to offend, as well as seek to improve pro-social bonds and influences. This chapter reviews the contribution and effectiveness of rehabilitative and reintegrative penalties in Britain. The chapter begins with a clarification on definitions and scope. It is summarized that there is a need to widen the scope of the evidence-based approach in rehabilitation and reintegration, particularly broadened in two ways: (1) increased concern with the impact of the whole of an offender’s supervision or correctional involvement, not just with programs and (2) expand to consider the operation of the wider criminal justice system within which rehabilitative efforts are located. Evidence-based approaches to rehabilitation and reintegration in Britain have shown some promising signs, but have not yet lived up to the high expectations generated by the international research literature.
