摘要/Abstract

摘要：

为探讨被动性社交网站使用对青少年限制性饮食的影响及其作用机制，本研究基于三重影响模型和客体化理论，采用问卷法对568名青少年进行调查。结果显示：(1)被动性社交网站使用、自我客体化、身体羞耻和限制性饮食两两均呈显著正相关，且均与自我同情呈显著负相关；(2)被动性社交网站使用能通过自我客体化的单独中介作用以及自我客体化和身体羞耻的链式中介作用间接影响限制性饮食；(3)自我同情在链式中介路径中对自我客体化和身体羞耻的关系起负向调节作用。本研究揭示了青少年限制性饮食形成的内部机制，研究结果拓展了三重影响模型和客体化理论，为青少年限制性饮食的干预提供了理论参考。

Abstract:

To explore the influence of passive social networking site use on adolescents’ restricted eating and its mechanism, based on the Tripartite Influence Model and Objectification Theory, this study investigated 568 adolescents by questionnaires. The results showed that: 1) passive social networking site use, self-objectification, body shame and restricted eating were all positively correlated, and all were negatively correlated with self-compassion; 2) passive social networking site use indirectly influenced restricted eating through the single mediating effect of self-objectification and the chain mediating effect of self-objectification and body shame; 3) self-compassion played a negative role in moderating the relationship between self-objectification and body shame in the chain mediating path. This study reveals the internal mechanism of the formation of adolescents’ restricted diet, and the results expand the Tripartite Influence Model and Objectification Theory, which provide a theoretical reference for the intervention of adolescents’ restricted diet.

Key words: adolescent, passive social networking site use, restricted eating, Objectification Theory, self-compassion
