The problem raised in the study is also due to the lack of a common conceptual framework explaining the conditionality of foreign students’ realization by subjective characteristics. The purpose of the paper is to present and analyze the results of an empirical study of self-attitude indicators as subject predictors of students’ self-realization in a foreign cultural environment. The study was conducted in 2019-20 among students of the Peoples’ Friendship University of Russia getting undergraduate and Master’s degrees in Humanities. 412 respondents aged 18-25 took part in the survey. The authors used “Multidimensional questionnaire of self-identity” method by S. I. Kudinov; “Test - questionnaire of self-attitude” method by V. V. Stolin, S. R. Panteleev; the self-assessment diagnostic technique by Dembo-Rubinstein in A. M. Prikhozhan’s modification; “Individual preferences of self-expression sphere” questionnaire by S. S. Kudinov; methods of mathematical and statistical analysis (descriptive statistics, cluster analysis, K. Pearson’s correlation analysis, factor analysis, the program of standard statistical package “Statistica-7.0”. In the course of an empirical study of students in a multinational university it was found that the respondents’ self-realization is carried out mainly in the course of educational activities. As a result of cluster analysis, three groups of respondents with dominant indicators of self-attitude have been identified, which were conventionally designated as positive-stable, negative-rigid and socially dependent type of self-attitude. It is determined that respondents with a positive-stable type of self-attitude demonstrate most successful self-fulfillment due to the expression of such personal qualities as self-acceptance, self-confidence, faith in their possibilities and abilities, self-management. At the same time, the greatest difficulties in self-realization are experienced by students with a socially dependent type of self-attitude, due to low self-esteem, external self-regulation and constant expectation that others would evaluate their activities, actions and reactions.
