As part of a large pan-European project on co-creating public services we supported the design of a programme in England that attempted to operationalise research on desistance, through a model of co-created, strengths-based working. We then evaluated its implementation and impact. The programme was implemented in a Community Rehabilitation Company. It was delivered in the context of rapid organisational change, often in response to rapidly changing external events and a turbulent policy environment. These factors impeded implementation. An impact evaluation did not identify a statistically significant difference in re-offending rates between the intervention group and a comparator group. However, in-depth qualitative evaluation identified positive examples of co-production and co-creation, with individual case managers and service users supportive and noting positive change. Taken as a whole our findings suggest that a co-created, strengths-based model of probation case management is promising but needs to be accompanied by wider systems change if it is to be embedded successfully.

作为一个关于共同创造公共服务的大型泛欧项目的一部分，我们支持在英格兰设计一个项目，该项目试图通过一个共同创造的、基于优势的工作模式来实施对贫困的研究。然后，我们评估了它的实施和影响。该计划在一家社区康复公司实施。它是在组织快速变化的背景下交付的，通常是为了应对快速变化的外部事件和动荡的政策环境。这些因素阻碍了实施。影响评估没有发现干预组和对照组之间的再犯罪率存在统计学上的显着差异。然而，深入的定性评估确定了共同生产和共同创造的积极例子，个别案例管理者和服务使用者支持并注意到积极的变化。总体而言，我们的研究结果表明，共同创建的、基于优势的缓刑案例管理模型很有前景，但如果要成功嵌入，还需要伴随更广泛的系统变革。
