青少年被动社交媒体使用与负面身体意象：自我客体化的中介作用

Adolescents’ Passive Social Media Use and Negative Body Image: The Mediating Role of Self-Objectification

摘要: 本研究关注青少年群体的身体意象问题。现有研究多集中于年轻女性或特定疾病患者，对正处于外貌与心理发展不平衡阶段的青少年探讨尚不充分。调查表明，以抖音、Bilibili、快手为代表的内容类社交媒体已成为中学生信息获取、社交与娱乐的主要渠道。其中，被动性使用方式往往比主动交互带来更显著的负面心理影响。这类平台作为身体形象的集中展示场域，充斥大量关于身体展示的信息，易使青少年将其内化为标准，并持续对自身进行审视与比较，进而可能形成消极身体意象。然而，被动性社交媒体使用影响负面身体意象的具体机制尚未明确。为此，本研究在文献分析基础上构建了一个中介模型，旨在考察自我客体化在二者之间的中介作用。

Abstract: This study focuses on body image issues among adolescents. Existing research has predominantly centered on young women or specific patient groups, while investigations into adolescents—who are in a stage of imbalanced physical and psychological development—remain insufficient. Surveys indicate that content-based social media platforms such as Douyin, Bilibili, and Kuaishou have become primary channels for middle school students to access information, engage in social interactions, and seek entertainment. Among these, passive usage patterns tend to exert more pronounced negative psychological effects compared to active engagement. As concentrated arenas for body image presentation, these platforms are saturated with idealized bodily symbols, which adolescents may internalize as standards, leading to persistent self-scrutiny and comparison, thereby potentially fostering negative body image. However, the specific mechanisms through which passive social media use influences negative body image remain unclear. To address this gap, this study constructs a mediation model based on a review of the literature, aiming to examine the mediating role of self-objectification in the relationship between the two.
