Key findings this quarter
Two requests are being published this quarter: The Thinking Skills Programme (2010-2019), and Lancashire Women – second request (2015-2021).
The Thinking Skills Programme (2010 – 2019)
There are two Thinking Skills Programme (TSP) reports which evaluate (a) the impact on reoffending behaviour, and (b) the impact on prison misconduct, for individuals who participated in the TSP. The TSP is an accredited offending behaviour programme designed and delivered by His Majesty’s Prison and Probation Service (HMPPS).
Impact evaluation of prison-based TSP on reoffending
The reoffending study involved a treatment group of 20,293 adults (18,555 males, 1,738 females) who participated in the TSP in custody between 2010 and 2019. Proven reoffending was measured over a two-year period from the point of release from custody.
Over a two-year period from release, men who participated in the TSP were less likely to reoffend, reoffended less frequently, and took longer to reoffend, compared to similar males who did not participate in the TSP. These results were statistically significant and the effect sizes were very small.
Results indicated that over a two-year period following release, females who participated in the TSP reoffended less frequently, compared to similar females who did not participate in the TSP. These results were statistically significant with very small effect sizes.
Impact evaluation of the TSP on prison misconduct
The prison misconduct study involved a treatment group of 13,891 adults (12,938 males, and 953 females) who participated in the TSP between 2011 and 2019.
The male headline analysis results showed that over a 6-month period after starting the TSP those who had participated were less likely to receive an adjudication compared to males who did not participate in the TSP and received an adjudication less frequently. These results had very small effect sizes and were statistically significant.
The female headline analyses showed that over a 6-month period after starting the TSP females who had participated in the TSP received any form of adjudication less frequently compared to those who did not participate in the TSP. This result had a very small effect size and was statistically significant.
Lancashire Women – Second request (2015-2021)
Lancashire Women support women involved, or at risk of involvement, in the criminal justice system. The gender specific organisation offers support around societal stigmas, housing, emotional wellbeing, education, employment, and family and relationships. This is the second JDL evaluation for Lancashire Women, looking at programme participants between 2015 and 2021.
The overall results show that those who took part in the Lancashire Women were less likely to reoffend, reoffended less frequently and took longer to reoffend than those who did not take part. These results were statistically significant.
Justice Data Lab service: available reoffending data
The Justice Data Lab team have brought in reoffending data for the second quarter of 2021 into the service. It is now possible for an organisation to submit information on the individuals it was working with up to the end of June 2021, in addition to during the years 2002 to 2020.
