WCPCG-2010In the present study effectiveness of an anger management training program which has been grounded on cognitive-behavior therapy principles was examined. The trainings were implemented to three groups of undergraduate students (N=28) concurrently, for a period of six weeks. A control group (N=28) was selected from the same sampling frame. Pre- and post-test measures were obtained by State-Trait Anger Scale (Ozer, 1994), with a period of 6-months in between. Results demonstrated the effectiveness of the training; mean post-test anger-control score was significantly higher than the mean pre-test anger-control score for the treatment group, and no significant differences were found within the control group
