社交网络使用与青少年身体不满意——影响与内在机理

Social Media Use and Adolescent Body Dissatisfaction—Impacts and Underlying Mechanisms

摘要: 研究旨在揭示社交网络使用影响青少年身体意象的作用机制及调节因素，为制定干预策略提供理论依据。通过定量分析与调节变量检验发现，社交网站使用程度、形式及行为通过体像比较与自我客体化路径显著降低青少年身体满意度，其中神经质、自恋倾向、完美主义等人格特质及自我接纳度、身份认同清晰度等认知因素具有显著调节效应。研究表明，未来需加强本土化实证研究，拓展样本多样性并融合多模态方法，通过优化理论模型构建多维干预体系，为缓解青少年身体意象困扰提供科学路径。

Abstract: This study aims to elucidate the mechanisms and moderating factors through which social media use influences adolescents’ body image, thereby providing a theoretical foundation for developing intervention strategies. Quantitative analysis and moderation tests reveal that the intensity, patterns, and behaviors of social media engagement significantly reduce adolescents’ body satisfaction through pathways such as body comparison and self-objectification. Notably, personality traits (e.g., neuroticism, narcissism, perfectionism) and cognitive factors (e.g., self-acceptance, identity clarity) exhibit significant moderating effects. The findings underscore the need for future research to enhance localized empirical studies, diversify sampling, and integrate multimodal methodologies. By refining theoretical models and constructing multidimensional intervention frameworks, this research seeks to establish a scientific approach to mitigating adolescents’ body image concerns.
