Abstract:Abstract： Objective: To study the characteristics of the effects that the different ethnic identity might bring upon the adolesents’ subjective well—being. Methods: 900 adolescents from Han, Qiang and Yi nationalities were assessed with China Adolescent Multidimensional Life Satisfaction Scale. Results: In general, adolescents from the three nationalities were at an upper middle level with their subjective well-being. The Yi were significantly more satisfied than their peers from Han and Qiang nationality with regard to the overall life satisfaction, family satisfaction, school satisfaction（P＜0.01）. Yet in regard of academic satisfaction, Qiang and Yi adolescents were significantly higher than the Han peers（P＜0.01）. The Qiang adolescents were significantly lower than the Yi in respect of the freedom satisfaction（P＜0.05）. In the negative emotions, the Yi’s negative experience is significantly higher than that of the Han and Qiang nationality（P＜0.001）; while in respects of the friendship satisfaction, school satisfaction, academic satisfaction and freedom satisfaction, there exist significant differences between different grades and different academic achievements( graded as excellent, good, fair and poor). And the mother’s occupation is found to have main effect upon the environment satisfaction of an adolescent. No obvious main effect upon the SWB factors is observed in respects of the gender, educational level and occupation of their parents. In view of interaction, a strong interaction is observed in all the dimensions of the subjective well-being, whether it is between the genders and the grades, between genders and academic performance, between grades and academic performance, or it is between the adolescent’s parental educational levels and parental occupations. In the various dimensions of subjective well-being there is no interaction lying in between genders, grades and academic achievements.
