This is a report of a survey conducted to examine self-esteem, self-efficacy, acculturation, and racial tension in a multiethnic San Francisco high school. A questionnaire was administered to a sample of 525 students, consisting of Blacks, Hispanics, Asians, Indochinese, Filipinos, and Caucasians. The questionnaire included demographic questions, the Racial Tension Scale, the Rosenberg Self-Esteem Scale, the Schwarzer Self-Efficacy Scale, and the Acculturation Scale of Hopkins Personality Inventory. The researchers hypothesized: (1) significant differences between ethnic groups on self-esteem, self-efficacy, and acculturation; (2) significant differences in degree of experienced racial tension reported by different ethnic groups; and (3) negative correlations between racial tension and the variables of self-esteem, self-efficacy, and acculturation. Results showed that different ethnic groups do experience differing degrees of racial tension in the same milieu and that significant differences exist between racial groups in self-esteem, self-efficacy and acculturation, as well as in family support and likeability. It is suggested that despite the potential for creating a prejudice-free society by desegregating schools, further efforts are needed to undo racism in an increasingly culturally pluralistic society. Appended to the study are statistical data obtained from the survey. (Author/AOS)
