Two groups in three pretest، posttest and follow up time level were measured. Applied measures in this study consisted of State-Trait Anger Expression Inventory and collected data were analyzed through Spss software by repeated measure analysis of variance. The results showed that the experimental group that receive CBT showed insignificant differences in anger reduction in compare with control group that don’t receive any therapy. Also the results of secondary hypotheses showed that there is significant differences in anger components that mean state anger، trait anger، anger controlling and introjection of anger in experimental group in compare with control group that don’t receive any therapy; in some components there were no differences for example in anger externalization and internalization. There is discussion about the results in theoretical approach and its importance in clinical intervention. On the whole we could apply the results of present study in valid and accurate assessment and diagnosis of the brain injury effects in legal medical centers and furthermore offer CBT services for this clinical population as non-medical treatment، efficient and inexpensive therapy.
