Objective　To explore the relationship among narcissistic personality, selfie behavior, appearance evaluation, and self-objectification of college students. Methods　A total of 270 college students were investigated with narcissism personality questionnaire, selfie behavior questionnaire, self-objectification scale, and appearance evaluation scale. Results　Narcissistic personality was positively correlated with selfie behavior, appearance evaluation, and self-objectification. Selfie behavior and appearance evaluation were positively correlated with self-objectification. Narcissistic personality not only directly affected the level of self-objectification of college students, but also indirectly affected the level of self-objectification of college students through three paths: the independent mediating role of selfie behavior, the independent mediating role of appearance evaluation, and the chain mediating role of selfie behavior and appearance evaluation. Conclusion　The relationship between narcissistic personality and college students' self-objectification level is influenced by the independent mediating role of selfie behavior and appearance evaluation, and the co-mediating role of selfie behavior and  appearance evaluation.
