The aim of this article is to examine the effects of a short-term one-to-one anger management program delivered to community-based offenders in Malta. The program delivered was the Individual Managing Anger Program (I-MAP), a Cognitive behavioural therapy (CBT) and mindfulness-based anger management intervention developed as an EU project. A randomized control trial (RCT)with waitlist controls was carried out to investigate the effects of I-MAP on the reduction in anger dysfunction among offenders serving a community-based sanction. Participants were 24 male offenders aged between 18 and 57. Eligibility for treatment was based on screening for anger dysfunction and success of interventions was determined through psychometric measures. All the statistical analyses carried out showed significant reduction in psychometric scores on anger symptoms. Results of the interventions show clinical significance. These results are discussed in light of recent research.
