Adolescence is one of the most sensitive stages of life in the development and perfection of physical, mental and social health. For some teenagers, this period has been associated with physical, psychological and social problems, which are a lot of risky behaviors and social harms [Today, in most schools, the aggression of teenagers is observed, and usually the person does not have the strength to control his behavior. In most cases, parents and guardians of schools have conflicts with teenagers, and their actions sometimes cause harassment to the extent that they are expelled from school. If adolescent aggression is not recognized and treated at school, their physical and mental health will be endangered and their academic failure will not be unexpected [According to Delvecchio and Olivery, aggression is distinguished from hostility. Because hostility is an aggressive attitude, but aggression is a visible act of harm [Sometimes, the terms anger, hostility, and aggression are used interchangeably. Anger can be considered an emotion, hostility an attitude, and aggression a behavior. According to definitions, anger is an emotion that serves as the foundation for hostility and aggression.

Also, in this region, evidence of conflict between female students in the school environment and also at home with their parents was reported. Although The characteristics of adolescence require that they experience more excitement. But the lack of emotion regulation in teenage girls causes confusion in relationships and also a drop in their education.Due to the difficulties of adolescence and the likelihood of high-risk behaviors, such as aggression, there is a need in our city for a method to avoid the occurrence of high-risk behaviors among female adolescents, and the Positive Youth Development Program can fill this need. Applying the study’s findings will assist the relevant authorities in developing and putting into practice aggression prevention programs and result in more successful teen-focused initiatives in families, schools, and other support systems. This program keeps teenagers from participating in harmful behaviors like aggression by emphasizing empowerment and creating a safe atmosphere.Given that little research has been conducted in Iran on the positive youth development program’s effect [
