ABSTRACT
OBJECTIVE: According to sociocultural theory, media is associated with detrimental effects on body image. Due to the popularity of social networking sites (SNS) and the prevalence of body image disturbance among young women, the association between them is worth further exploration. This study examined the relationship between photo activity on SNS and body dissatisfaction (BD) and the roles of thin-ideal internalization (TII) and body appreciation (BA) in this relation. MATERIALS AND METHODS: A total of 746 Chinese female undergraduate students (mean age 20.34 ± 1.47 years) completed a questionnaire measuring SNS photo activity, TII, BD, and BA. RESULTS: (1) Photo activity on SNS was positively associated with BD (r = 0.10, p < 0.01), and TII could mediate this relation (ß = 0.07, 95% CI = [0.04, 0.10]). (2) Both the direct effect of SNS photo activity on BD (ß = -0.08, p < 0.05) and the mediating effect of TII (ß = -0.09, p < 0.01) were moderated by BA. Specifically, these associations were more pronounced for students with lower BA. CONCLUSION: People exposed to ideal photos or images can shape women's body image perception via TII, whether in the age of traditional media or the Internet, and BA did not buffer the effect of ideal photos on internalization. Our findings could provide practical suggestions for rational photo activity on SNS and the intervention for BD.
