Abstract: The main purpose of this study was to investigate the effect of stress management training on anger control and life quality of student in high schools of Alborz province. This is a quasi-experimental study and the pretest-posttest design is related to the control and experimental groups. The statistical population of this study included all high school students in Alborz province who were studying in the academic year 2015-2016. For this purpose, 70 high school students were selected by stratified random sampling and were randomly divided into two groups of 35 subjects under the titles of experimental and control groups. The stress management training package of Valla (1995) and Aghajani (2003) was presented for the experimental group in 10 sessions (about 2 hours in the afternoon) three times a week inside high school. The data before and after education were assembled via Moghimi's anger control questionnaire (2001) and World Health Organization Quality of Life questionnaire (1996). The results of the analysis of covariance between the two groups indicated that there was a significant difference between the direct confronting, solving the planned problem and the positive re-evaluation and as a result, training was effective on coping strategies.
