The topicality of the study presented in the article is determined by the importance of studying this aspect due to the fact that representatives of different ethnic groups may experience difficulties in the adaptation process if they fail to act in a relevant way, if there is mismatch between the expected and the actual behaviour of the subjects. The aim of the article is to consider the possibility of sanogenic reflection as a condition for psychological adaptation of students in multiethnic environment of the university. The article presents a correlation analysis of indicators of psychological adaptation of students in multi-ethnic educational environment with specific features of ethnic stereotypes and discusses the possibilities of sanogenic reflection to understand their own actions based on specific ethnic stereotypes and their abilities to change their own views, attitudes and behaviors adequately to situations in the new environment. The obtained data show a correlation of indicators of volumes of protective reflection from shame, resentment, guilt with aggression against others, and the inclusion of protective reflection from feeling guilt and aggression against themselves. Scientific novelty of the study is that psychological adaptation of representatives of different ethnic groups is considered from the point of view of the affectivebehavioral approach, taking into account the fact that manifestation of protective reflection as a factor reducing the degree of adaptation is associated with manifestations of ethnic stereotypes, transformation of which is ensured by the development of sanogenic reflection. It is experimentally proved that the development of sanogenic reflection has an impact on adaptation, what allows to consider sanogenic reflection as a condition for development of a personality. The data presented in the article orient representatives of different ethnic groups to effective communication in multi-ethnic environment.
