Introduction: Using students in the Liangshan Yi autonomous prefectures of southwestern China ( = 585; 13-15 years old), we examined (i) the effects of students' perception of their teachers' ethnic-racial socialization on their ethnic identity and mental health outcomes of depressive and stress symptoms; (ii) the effects of students' ethnic identity on their depressive and stress symptoms; (iii) the differential associations among these factors in Yi ethnic minority versus Han cultural majority students.
Methods: We conducted a cross-sectional survey and used multistage sampling to collect the information. Chinese-validated standardized measures were used: the Patient Health Questionaires-9, Children's Revised Impact of Event Scale-8, Multigroup Ethnic Identity Measure, Cultural Socialization Scale, and Teachers' Attitude on Adoption of Cultural Diversity Scale.
