Relevance. In situations of forced resettlement, most Ukrainians demonstrate active adaptation to new living conditions, but they may not develop a psychological state of internal balance and well-being. The reason for this is communication difficulties, the migrant's inability to integrate into local communities. This raises the problem of "social adaptation-maladaptation" - the leading mechanism of interaction between an individual and a new social environment. Methodology. To prove the hypothesis: long-term psychological maladaptation leads to the marginalization of the individual and the formation of special marginal communities, it should be assumed that 1) subjective indicators of an individual's adaptability in a group are: a) understanding of the system of relationships and role relations in the group; b) acceptance of one's own role, accompanied by a sense of emotional comfort; c) experiencing a state of personal well-being in this environment; 2) the degree of adaptation - maladaptation of a person depends on: the significance of changes in the objective circumstances of life and subjective readiness for self-change. Results. Four limitations of the adaptive paradigm of socialization have been identified: 1) in difficult life circumstances, adaptation allows an individual to survive, but the quality of his life is significantly reduced and there is a threat of consolidating unproductive life strategies. 2) adaptation does not always lead to an increase in the well-being of the individual and can become a significant factor in his neurotization. 3) the reverse side of adaptation is the marginalization of the individual and the formation of marginal communities. Adaptation performs a stabilizing function in society, but also acts as a limitation for the development of personality and social innovation. An important addition to the adaptation model of socialization should be the idea of social integration of the individual.
