Introduction: Teachers face several problems (voluminous work, students' academic decline, inadequate wages and benefits) due to the nature of their job that all of these problems are effective on their health and continuing of these injuring problems raise their susceptibility and ultimately may lead to disease and reduced life expectancy among people. Objective: The purpose of this study was to examine the effectiveness of group Logo therapy on life expectancy in high school teachers of Miyaneh city in the educational year of 2011- 2012.Materials and Methods: In this study, the method of semi-experimental and the design of pre-test and post-test and follow-up with group control is used. For this purpose, of the statistical population that including 200 members of teachers, 60 individuals were selected through accessible method and of these, 30 people were place in the experimental group and 30 people in the control group. The method of group logo therapy was performed for 8 sessions, two sessions per week for the experimental group and the control group received no training. All the subjects completed Miler's life expectancy scale before the start of training and after that. The next step, in order to measure survival training after 1 month, follow-up test of life expectancy was performed. To analyze the data, SPANOVA was used.Results: The results of ANOVA showed that life expectancy in the experimental group was significantly higher than the control group (p <0.05) and life expectancy in post-test is higher than the pre-test and follow up and in the follow-up period is higher than the pre-test (p<0.001).Conclusion: In general, it could be said that group logo therapy could be used as an independent method or in conjunction with other therapies to increase life expectancy.
