Are prison-based therapeutic communities effective? Challenges and considerations

The purpose of this paper is to detail the impact and efficacy of Her Majesty's Prison and Probation Service ((HMPPS) Therapeutic Communities (TCs) (both democratic and hierarchical). This paper outlines recent developments in the TC literature, to provide readers with an up-to-date overview of the outcomes of prison-based TC treatment, while highlighting the strengths and challenges of this treatment approach. Trends within the research are discussed, and the authors draw attention to any gaps in the current knowledge.

This paper uses a narrative literature review approach to review the most current literature around the effectiveness of prison-based TCs in HMPPS. Academic literature published predominantly from 2010 onwards is discussed because of limited literature review publications on this topic post-2010. To obtain literature, searches of relevant databases were conducted, and/or clinical leads at prison sites were contacted for relevant publications.

There is a body of research which demonstrates that TCs are an effective form of treatment for people with an offending history and personality difficulties. Evidence indicates that Democratic TC treatment plays a part in reducing reoffending rates, as well as improving psychological features. Further research is needed in a number of areas, specifically with female offenders and individuals who undertake treatment in hierarchical TCs in the UK. It is also suggested that TC treatment aftercare may help to further the positive outcomes identified.

To the best of the authors' knowledge, there is no up-to-date review of the impact and efficacy of HMPPS TC treatment. This paper reflects on available research within the current context of TC treatment and provides an original overview of the current UK TC practice. It has value in recommending areas for further research and consideration.
