A sense of one's own identity is the main factor in the harmonious development of a personality. A person's identity is formed in the process of social development of personality and is largely determined by the object relationships that develop in the family. In daily clinical practice, psychologists are increasingly confronted with the borderline personality structure that manifests itself in clients, and borderline personality organization is closely related to the problem of Ego strength and identity. Although the issue of identity has been studied quite deeply, the relationship between family well-being and the identity of a mature person has not been studied enough. Especially little attention is paid to the formation of identity in children from disadvantaged families. The purpose of this study is to identify the factors contributing to the formation of identity in children from disadvantaged families. The article presents the results of an empirical study that showed that people from disadvantaged families have not formed an identity. Correlation analysis revealed the individual traits characteristic of such people. If psychologists manage to develop these traits, they will be able to have a more targeted impact on the formation of identity in these people.
