The paper presents the results of a study of the connection between the parameters of the communicative tolerance and the intercultural adaptation in the international students from a multinational university (Peoples’ Friendship University of Russia). A total of 337 respondents took part in the research, including 182 young men and 155 young women from five parts of the world: Latin America, Asia (China), Arab countries, Africa, the countries of the Central Asian region. The level of the communicative tolerance was measured with the technique “General communicative tolerance” by V.V.Boyko. The Questionnaire of the adaptation of the person to the new socio-cultural environment (APSCE) by L.V.Yankovsky, in T.G.Stefanenko and M.S.Panov’s modified version was used to define the features of the intercultural adaptation of the international students. The Kruskal–Wallis non-parametrical criteria, the Analysis of Variance (MANOVA), and the correlation analysis (Spearman Rank Correlations) were used for the statistical analysis. The study revealed that the rates of the communicative tolerance, as a whole, are positively related to the efficiency of the intercultural adaptation of the international students in Russia (especially for the students from Africa, Arab countries and Latin America). © 2015 Mediterranean Center of Social and Educational Research.
