The aim of the present research study was to compare the relationships between identity (nationalistic, religious and ethnic), socialization processes (home and school), and psychological resilience (self-esteem, self-efficacy, and well-being) of Arab-Palestinian and Jewish high school students in Israel.317 tenth and eleventh grade students (163 Arab-Palestinian students including 93 girls and 70 boys; and 154 Jewish students including 70 girls and 84 boys) participated in the study. The research was conducted in two state Arab-Palestinian schools, one state secular-Jewish school, and one state religious-Jewish school.The research employed a series of questionnaires. First, a background questionnaire was used to collect basic data about the students; a second questionnaire assessed the nationalistic and religious socialization of the Jewish teenagers and the nationalistic, religious, and ethnic socialization of the Arab-Palestinian adolescents; a third questionnaire assessed the salience of national and religious identity among the Jewish participants, and the salience of national, religious, and ethnic identity among the Arab-Palestinian participants; a fourth questionnaire examined indices of psychological resilience, namely self-esteem, self-efficacy, and the sense of well-being of the Arab-Palestinian and Jewish students. The research findings indicate differences between the socialization processes experienced by the Arab-Palestinian students and those experienced by the Jewish students. The nationalistic socialization experienced by the Jewish adolescents was stronger than that experienced by the Arab-Palestinian adolescents, while the Arab-Palestinian adolescents experienced stronger religious socialization than that experienced by the Jewish adolescents. In addition, the level of religious identity was higher among the Arab-Palestinian participants than among the Jewish participants. On the other hand, there were no significant differences between the two groups regarding salience of national identity. The findings did not indicate differences between the two groups with regard to self-esteem and well-being. However, the self-efficacy of the Arab-Palestinian students was found to be higher than that of the Jewish students.
