<p>This study provides an exploratory extension of objectification theory to same-sex, non-romantic contexts within a non-WEIRD (Chinese) sample. Specifically, it examines how appearance-based and body-sexualized comments trigger self-objectification and enjoyment of sexualization under different relational situations. Using a 3 (comment source: stranger vs. colleague vs. friend) × 2 (comment type: appearance-related vs. sexualized body-related) × 2 (comment valence: positive vs. negative) design, we exposed 395 heterosexual, ethnically Chinese adults (202 women, 193 men; M age ≈ 21 years) to objectifying comments. Findings indicate that women exhibited valence-sensitive and relationship-dependent responses. For female participants, negative comments were associated with heightened self-objectification, and self-objectification was lowest when comments were received from friends, with observed effects ranging from small to large (partial η² ≈ .003–.333) across analyses of female participants. In contrast, men showed relatively stable, hedonic responses across conditions, with self-objectification and enjoyment of sexualization largely unaffected by comment valence or relational context (non-significant or trivial effect sizes). These results suggest potentially distinct pathways for women and men in same-sex objectification contexts in China. By positioning same-sex objectification within a collectivist cultural background, this study emphasizes the role of interpersonal valence and intimacy in shaping self-objectification and enjoyment of sexualization, contributes to a growing but still limited body of non-Western research, and highlights the need for replication across diverse sociocultural settings.</p>
