Whilst previous research has generally supported the thesis that anger management is an effective intervention for anger problems in general there remains a need to determine its effectiveness with offender populations. This paper reports the results of a controlled outcome study of a 20 h anger-management program offered to offenders. Those receiving treatment showed improvements in their knowledge about anger, but showed little change on measures of anger and anger expression when compared to waiting-list controls. Scores on measures of treatment readiness and level of need for treatment were however,correlated with post-treatment improvement. These findings are discussed in terms of their implications for the assessment and selection of appropriate participants for offender anger-management programs.enCopyright 2010 ElsevierangertreatmentoffendersoutcomeJournal article10.1016/j.brat.2009.10.0052-s2.0-76849097593
