The effect of emotional and psychological well-being on the level of aggression in high school students

The research was conducted to examine the relationship between emotional and psychological well-being and aggression levels in high school students. The research was conducted with 195 students who met the sample criteria and were studying in a high school in Mersin province between July 2024 and May 2025. In the analysis of the data, descriptive statistics, Pearson correlation, linear regression, t-test, one-way analysis of variance and post hoc tests were used with the appropriate statistical package program. According to the obtained data; 79.5% of the students participating in the study were female, 20.5% were male, and when the age distribution was examined, it was determined that the highest number of students was 14 years old (33.0%). It was determined that emotional and psychological well-being has a significant and negative effect on aggression. The research findings reveal that emotional and psychological well-being has a significant and negative effect on the sub-dimensions of aggression, namely physical and verbal aggression, hostility and anger. In the study, emotional and psychological well-being explained 14.8% of the variance in aggression, indicating that well-being is an important determinant of aggression. As a result of the study, it was determined that children with high emotional and psychological well-being had low levels of aggression. It is recommended that school health nurses plan training to increase children's psychological well-being. Keywords: Adolescent,Emotional Well-being, Nurse, Psychological Well-being, Aggression
