Body dissatisfaction is particularly prevalent during adolescence and has recently been linked to stress in females and males. However, prospective studies are needed to better understand the relationship between stress and body dissatisfaction. The present study investigates the direction of this association and the mediating role of self-esteem and body image importance. A sample of 298 adolescent females and males in Grades 7 to 10 (ages 12 to 17 years) were surveyed at two time points over a one-year period. Hierarchical regression analyses revealed that stress significantly predicted body dissatisfaction one year later. Furthermore, a multiple mediation analysis controlling for gender revealed a significant indirect effect in both cross-sectional and longitudinal models, indicating that stress predicts reductions in self-esteem and increases in body importance, which in turn predict body dissatisfaction. These findings suggest that stress, self-esteem, and body importance should be included in programmes aimed at improving body dissatisfaction.
身体不满在青春期尤为普遍，最近有研究表明，身体不满与女性和男性的压力有关。然而，需要前瞻性研究来更好地理解压力和身体不满之间的关系。本研究调查了这种关联的方向，以及自尊和身体意象重要性的中介作用。在为期一年的时间里，对 7 至 10 年级（12 至 17 岁）的 298 名青少年女性和男性进行了两次调查。层次回归分析显示，压力在一年后显著预测了身体不满。此外，在控制性别后进行的多项中介分析表明，在横断面和纵向模型中均存在显著的间接效应，这表明压力预测了自尊的降低和身体重要性的增加，而这又反过来预测了身体不满。这些发现表明，压力、自尊和身体意象重要性应该纳入旨在改善身体不满的计划中。
