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.

Pre-release access

The bulletins are produced and handled by the Ministry’s analytical professionals and production staff. Pre-release access of up to 24 hours is granted to the following persons: Minister of State, Lord Chancellor and Secretary of State for Justice, Special Advisers, Permanent Secretary, Deputy Head of News, 1 Director General, 6 press officers, 18 policy officials, and 5 analytical officials. Relevant Special Advisers and Private Office staff of Ministers and senior officials may have access to pre-release figures to inform briefing and handling arrangements.

The Justice Data Lab has been launched as a pilot from April 2013. During this pilot, a small team from Analytical Services within the Ministry of Justice will support organisations that provide offender services by allowing them easy access to aggregate reoffending data, specific to the group of people they have worked with. This will support organisations in understanding their effectiveness at reducing re-offending.

The service model involves organisations sending the Justice Data Lab team details of the offenders they have worked with along with information about the specific intervention they have delivered. The Justice Data Lab team then matches these offenders to MoJ’s central datasets and returns the reoffending rate of this particular cohort, alongside that of a control group of offenders with very similar characteristics in order to better identify the impact of the organisation’s work.

There are three publication types:

• A summary document of the requests received to date and the findings of the Justice Data Lab pilot for this month (1 April 2014 to 30 April 2014).
• Tailored reports about the reoffending outcomes of services or interventions delivered by each of the organisations who have requested information through the Justice Data Lab pilot. Each report is an Official Statistic.
• All of the Justice Data Lab findings to date are presented in a separate file. This file contains all findings described in the summary document in the form of tables, organised by intervention type. This is intended to be a more accessible version of all of our findings to date.

Note to users

From this month, the summary document will contain only findings being published within the month’s reporting round. All findings to date will continue to be published in the more accessible format.

We welcome any feedback on this change, or on the Justice Data Lab Statistics more generally.

Main findings to date

To date, the Justice Data Lab has received 85 requests for re-offending information, including 59 reports which have already been published. A further 2 are now complete and ready for publication, bringing the total of completed reports to 61.

To date, there have been 16 requests that could not be processed as the minimum criteria for analyses through the Data Lab had not been met, and one further request that was withdrawn by the submitting organisation. The remaining requests will be published in future monthly releases of these statistics.

Of the 2 reports being published this month:

• One report looks at the effectiveness of receiving yoga and mediation materials from The Prison Phoenix Trust. This analysis shows that the impact of this intervention on re-offending is currently inconclusive.
• One report looks at the effectiveness of the Time for Families relationship course. This analysis shows that the impact of this intervention on reoffending is also currently inconclusive.

Reasons for an inconclusive result include; the sample of individuals provided by the organisation was too small to detect a statistically significant change in behaviour; or that the service or programme genuinely does not affect reoffending behaviour. However, it is very difficult to differentiate between these reasons in the analysis, so the organisations are recommended to submit larger samples of data when it becomes available. Detailed discussion of results and interpretation is available in the individual reports.

Reminder about the Justice Data Lab Service

In March 2014 we announced that the Justice Data Lab will continue to be piloted for another year. We are keen that the Justice Data Lab service continues to improve and, following feedback from users and internal consideration on our processes, we have specified a number of improvements that we intend to bring into the service over the next year. These improvements, as well as recommendations for users of the service are discussed in detail in the document ‘Justice Data Lab; The pilot year’ which was published alongside the summary statistics for March 2014.

The bulletin is produced and handled by the Ministry’s analytical professionals and production staff. Pre-release access of up to 24 hours is granted to the following persons: Ministry of Justice Secretary of State, Parliamentary Under Secretary of State, Permanent Secretary, Director of Sentencing and Rehabilitation Policy unit, relevant Policy Advisers for reducing re-offending (two persons in total), Pol

Key findings this quarter

One request is being published this quarter: Spark Inside (2016-2018).

Spark Inside

Spark Inside works with young male offenders, who are within 6 months of the end of their custodial sentence. This is the first JDL evaluation for Spark Inside, looking at programme participants between 2016 and 2018.

The overall results do not show that the programme had a statistically significant effect on a person’s reoffending behaviour. They suggest more people need to be available for analysis to determine the way in which the programme affects the one-year proven reoffending rate, the frequency of proven reoffences, and the time taken to reoffend.

Justice Data Lab service: available reoffending data

The Justice Data Lab team have brought in reoffending data for the first quarter of 2020 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 March 2020, in addition to during the years 2002 to 2019.

Pre-release access

The bulletin is produced and handled by the Ministry’s analytical professionals and production staff. Pre-release access of up to 24 hours is granted to the following persons: Minister of State, Lord Chancellor and Secretary of State for Justice, Special Advisers, Permanent Secretary, Head of News, Deputy Head of News, 2 Director Generals, 5 press officers, 3 policy officials, and 10 analytical officials.

Key findings this quarter

Two reports are being published this quarter: Prisoners Education Trust (4th analysis) and Resolve accredited programme.

Note: Following the publication of the original impact evaluation for the Resolve accredited programme detailed below, a supplementary appendix including additional analysis and descriptive statistics was published in Justice Data Lab statistics: October 2021.

Prisoners’ Education Trust (4th analysis)

Prisoners’ Education Trust (PET) funds prisoners to study courses via distance learning in subjects and at levels that are not generally available through mainstream education.

This analysis looked at the employment outcomes and reoffending behaviour of 9,041 adults who received grants for distance learning through Prisoners’ Education Trust (PET) schemes between 2001 and 2017. This analysis is a follow up of previous PET analyses which looked at the reoffending behaviour and employment outcomes of a smaller group of people.

The overall results show that those who received PET grants were less likely to reoffend in the year after their release from prison and more likely to be employed, compared with a group of similar offenders who did not receive these grants.

Resolve accredited programme

Resolve is a moderate intensity accredited programme designed and delivered by HMPPS. The prison-based programme is a cognitive-behavioural therapy-informed offending behaviour programme, which aims to improve outcomes related to violence in adult males who are of a medium risk of reoffending.

The analysis looked at the reoffending behaviour of 2,509 adult males who participated in the Resolve custody programme at some point between 2011 and 2018 and who were released from prison between 2011 and 2018. It covers one and two-year general and violent reoffending measures.

The headline results for one-year proven general reoffending (includes all reoffending) show that those who took part in the programme in England and Wales were less likely to reoffend, reoffended less frequently and took longer to reoffend than those how did not take part. The headline results for two-year proven general reoffending show that those who took part were less likely to reoffend, reoffended less frequently and took longer to reoffend that those how did not take part. These results were statistically significant.

For proven violent reoffences (a subset of general reoffending), the headline one and two-year results did not show that the programme had a statistically significant effect on a person’s reoffending behaviour, but this should not be taken to mean it fails to have an effect.

Further analyses were also conducted to examine the specific effects of Resolve on relevant sub-groups for proven general reoffending and violent reoffending. Among the one-year violent sub-analyses, those who only participated in Resolve were significantly less likely to reoffend violently and reoffended violently less frequently than those who did not take part. There were no statistically significant sub-analyses for the two-year violent measures.
