The present study aimed to explore the relationships among college students’ loving status(in love or single), self-rated attractiveness and appearance-based rejection sensitivity. A sample of Chinese college students(N=549) was recruited randomly from Beijing, Sichuan and Anhui provinces who completed the Loving Status Questionnaire, Appearance-based Rejection Sensitivity Scale, Rejection Sensitivity Questionnaire, Social Comparisons Based on Appearance and Self-Rated Attractiveness in the form of classes. Results indicated that: 1) college students’ loving status, self-rated attractiveness and appearance-based rejection sensitivity significantly correlated with one another; 2) college students’ loving status could positively predict self-rated attractiveness, and negatively predict appearance-based rejection sensitivity; 3) self-rated attractiveness played a fully mediating role between loving status and appearance-based rejection sensitivity(indirect effect was 0.47), namely loving status reduced the level of appearancebased rejection sensitivity by promoting the self-perception of individuals’ attractiveness.
