One of the pressing problems of modern society is the aggressive behavior of adolescents. Despite the large number of studies devoted to this topic, the question of defining aggression as an interdisciplinary phenomenon, as well as the causes and conditions for adolescents aggression, remains controversial and requires additional study due to the fact that today aggression is not just a behavioral reaction, but can also transform into a stable model of deviant behavior. Society has an objective need to resolve the issue of preventing teenage aggression and clarifying its causes. The author has made an assumption and empirically verified that aggressive behavior in its extreme form - in the form of deviant behavior - has a connection with unmet needs and the level of self-esteem of a teenager. In our study, we rely on the work in the field of aggressive behavior and deviant behavior of E.V. Leus and self-esteem of L.S. Vygotsky. The study was conducted using methods for diagnosing the level of aggressiveness of A. Bass and A. Darka to determine typical forms of aggressive behavior, assess the propensity for deviant behavior of E.V. Leus, studying the degree of satisfaction of the needs of students A.A. Andreev and the test “Personality Self-Esteem” by S.V. Kovaleva. As a result of the study, it was found that a high level of aggression manifests itself in a pronounced tendency to deviant behavior. It has also been established that the level of aggression is directly related to unmet needs for safety and social contacts, and a connection between a high level of aggression and an inadequate (overestimated or underestimated) level of self-esteem of adolescents has been identified.
