Samenvatting

For the purpose of a social cost-benefit analysis on the Dutch probation services, a typology of probationers supervised in 2016 (N = 12,017) was developed through a combination of qualitative and quantitative methods. The theoretical basis for the typology consists of three pillars: Individual readiness to change, Contextual readiness to change and Punishable behaviour. A factor analysis of RISc 4.0 items was used to operationalise this basis. A cluster analysis yielded 15 unique types. This typology makes it possible to determine the added value of probation with more precision.
