The aim of the present study was to assess the effectiveness of a brief group-based anger management intervention with young male offenders. Eighty-seven prisoners were assessed as suitable for the intervention. Fifty of these made up the experimental group and 37 the control. Prior to intervention prisoners completed a self-report anger questionnaire (Anger Management Assessment questionnaire: AMA). Prisoners were also assessed by officers on a checklist addressing angry behaviour (Wing Behaviour Checklist: WBC). Both measures were completed approximately two weeks before the date of the intervention and eight weeks after the intervention (and while the control group remained on the waiting list). It was predicted that the experimental group would show significant improvements in both measures following intervention and that no such change would be observed in the control group. This hypothesis was supported, with significant improvements observed in the experimental group and no change observed in the control. Aggr. Behav. 30:174–185, 2004. © 2004 Wiley-Liss, Inc.
