Abstract. The current study examined the links between viewing female and male sexualized Instagram images (SII) and body image concerns within the three-step process of self-objectification among adolescents aged 13–18 years from Germany ( N = 300, 61% female). Participants completed measures of SII use, thin- and muscular-ideal internalization, valuing appearance over competence, and body surveillance. Structural equation modeling revealed that SII use was associated with body image concerns for boys and girls via different routes. Specifically, female SII use was indirectly associated with higher body surveillance via thin-ideal internalization and subsequent valuing appearance over competence for girls. For both girls and boys, male SII use was indirectly linked to higher body surveillance via muscular-ideal internalization. Implications for the three-step model of self-objectification by sexualized social media are discussed.

暴露于性感 Instagram 图像与女孩和男孩的身体形象问题之间的联系

摘要。目前的研究检查了德国 13-18 岁青少年（N = 300，61% 女性）在自我客观化的三步过程中观看女性和男性性感 Instagram 图像 (SII) 与身体形象问题之间的联系。参与者完成了对 SII 使用、瘦和肌肉理想内化、重视外表胜过能力和身体监测的测量。结构方程模型显示，SII 的使用与男孩和女孩的身体形象问题通过不同的途径相关联。具体来说，女性 SII 的使用与更高的身体监视间接相关，通过瘦理想内化和随后重视女孩的外表而不是能力。对于女孩和男孩来说，男性 SII 的使用与通过肌肉理想内化的更高的身体监视间接相关。
