The study focused on analyzing the impact of ethnic and national identity on the ethnonational attitudes among young people living in the North Caucasus. The study involved students residing in the Chechen Republic (214 subjects aged 16—19 years (mean 17.8), girls — 97, boys — 117). We used: 1) Ethnonational attitudes scale; 2) Technique for studying expression of ethnic and national identity; 3) Interethnic Attitudes questionnaire; 4) General Social Attitudes Scale by E.Frenkel-Brunswik. The outcomes of the research indicate that national identity is a weak predictor of ethnonational attitudes. It is associated with ethnic identity, but does not play any significant role in the formation of interethnic relationships. However, ethnic identity does shape the feeling of pride and other positive feelings that one has about his/her own “nationality”. To a lesser extent, but still statistically significant, subjective importance of one’s ethnicity is associated with hostility towards other nationalities and with negative assessment of social equality and cultural diversity.
