This study aimed to determine whether self-esteem and negative affect sequentially mediate the relationship between body dissatisfaction and disordered eating. A total of 806 adolescents (61.8% females) completed the Drive for Thinness, Bulimia, and Body Dissatisfaction subscales of the Eating Disorder Inventory-2, the Anxiety and Depression subscales of the General Health Questionnaire-28, and the Negative Self-beliefs subscale of the Eating Disorder Belief Questionnaire. Mediational analyses showed that body dissatisfaction had both direct and indirect effects through self-esteem and negative affect on disordered eating. It was also observed that negative self-esteem mediated-completely in boys and partially in girls-the relationship between body dissatisfaction and negative affect.
本研究旨在确定自尊和负性情绪是否在身体不满与饮食失调之间的关系中起序列中介作用。共有 806 名青少年（61.8%为女性）完成了饮食失调问卷-2 的消瘦、贪食和身体不满分量表、一般健康问卷-28 的焦虑和抑郁分量表以及饮食障碍信念问卷的消极自我信念分量表。中介分析表明，身体不满对饮食失调既有直接影响，也有通过自尊和负性情绪的间接影响。此外，还观察到在男孩中，消极自尊完全中介，而在女孩中部分中介了身体不满与负性情绪之间的关系。
