Objective: To explore the relationship among appearance-related social pressure, body image, dual self consciousness and perceived stress, and reveal the mediating role of dual self-consciousness and perceived stress in the re lationship. Methods: 579 young women aged 18～35 years old were investigated using four scales: The socio-cultural attitudes towards appearance questionnaire-4 (SATAQ-4), self-consciousness scale (SCS), the perceived stress scale (PSS-14) and body image states scale (BISS). Results: Body image was negatively correlated with appearance-related social pres⁃ sure, perceived stress and BMI, and positively correlated with private self-consciousness; Appearance-related social pres⁃ sure negatively predicted body image; Public self-consciousness and perceived stress had a significant chain mediating ef⁃ fect in the relationship between appearance-related social pressure and body image, and perceived stress had a significant mediating effect in it. Conclusion: Appearance-related social pressure not only directly negatively predicts body image, but also negatively affects body image through the mediating effect of perceived stress and the chain mediating effect of pub⁃ lic self-consciousness and perceived stress.

目的：探讨双自我意识、压力感知在外表社会压力和身体意象之间的中介作用。方法：采用外表社会压力、自我意识、压力感知、身体意象等4个量表对579名18～35岁年轻女性开展问卷调查。结果：身体意象水平与外表社会压力、压力感知和BMI显著负相关，与私我意识显著正相关；外表社会压力显著负向预测身体意象水平；压力感知在外表社会压力和身体意象关系中的中介作用显著；公我意识→压力感知在外表社会压力和身体意象关系中的链式中介作用显著。结论：外表社会压力能直接负向预测身体意象水平，也能通过压力感知的中介作用和公我意识→压力感知的链式中介作用负向预测身体意象水平。
