Intervention description

The Peterborough SIB is intended to reduce the reconviction rates of short-sentence male prisoners leaving HMP Peterborough. The One Service contracted four organisations, St. Giles Trust, Ormiston Children and Families Trust, YMCA and SOVA, to deliver its core activities. St. Giles Trust and Ormiston Children and Families Trust focus on the immediate needs of an o ender and his family before and after he is released from prison. These needs include accommodation, medical services, family support, employment and training, bene ts and  nancial advice.Participants voluntarily refer themselves into 'The One Service'. St Giles Trust workers interviewed offenders to assess their needs. supported offenders before release, at the point of release, and into the community. The Ormiston Children and Families Trust supported offender's children and families in that time. SOVA and YMCA provided longer-term, lower-intensity support.
