A study of the chances of reoffending over a given time period.
Reoffending patterns were studied in terms of their hazards: the chance of reoffending in a given time period if reoffending had not occurred in an earlier time period.
The results demonstrated that the hazards for all types of reoffending were highest in the first few months following sentence or discharge, but some types of reoffending had a much more persistent hazard than others.
The value of the Offender Assessment System reoffending predictors in segmenting different types of reoffending according to risk was also demonstrated.
The findings could be combined with existing literature on offender treatment to inform the delivery of interventions and supervision designed to reduce reoffending.
