Aggression replacement training (ART) aims to prevent aggression by improving people's social skills, building up their impulse and anger control and developing their moral reasoning. It was originally developed for aggressive youths but is also available in a revised format for adult offenders. A study of 197 offenders by researchers at Leicester and Liverpool universities compared violent offenders who had been allocated to the programme with a control group. Those who had taken part in the training had a 13.3% reduction in reconviction. Those offenders who failed to complete the programme were more likely to reoffend than similar people who had never been on it or who had completed the course.
