Emotional intelligence involves recognizing one's emotions and using them to make appropriate decisions in life. The purpose of this study is the influence of emotional intelligence education techniques on psychological well-being and aggression of athlete students at the Karadeniz University. The research type is quasi-experimental and it is plan is pre- and post-test with the control group. The statistical population of the study includes all athlete students of the Karadeniz University in different fields of sports. By using relative random sampling among various and active sport fields, about 60 individuals were chosen among different fields (in the form of available sampling) and they were set randomly in the experimental and control groups. 16 sessions of education were used based on emotional intelligence education protocol. The protocol is taken from Bradbury and Graves program. For gathering the data, Buss and Perry aggression questionnaires and Reef psychological well-being questionnaire were used. Multivariate variance (Mancoa) was used in order to examine the hypothesis. Research results show that by using pretest control, there are significant differences among athlete students of experimental and control groups in terms of aggression(P < 0.01) and psychological well-being (p < 0.01). As a result, it can be concluded that emotional intelligence education has a significant impact on the psychological well-being and aggression of athlete students and it causes the increasing of psychological well-being and decreasing of aggression among athlete students.
