Low self-esteem and low self-directedness (SD) are considered a risk factor for the development of eating disorders (EDs). The aim of this study was to test the hypothesis that low self-esteem and low SD lead to a higher risk for EDs through the mediation of anxiety and depression.
Seventy-seven female teenagers answered the Eating Disorder Inventory 3 (EDI-3), the Intolerance of Uncertainty Scale (IUS), the Temperament and Character Inventory-Revised (TCI-R), the Rosenberg Self-Esteem Scale (RSES), and the State and Trait Anxiety Inventory (STAI), and the Symptom Checklist-90-Revised (SCL-90-R). To test the hypothesis, a structural equation model (SEM) was used.
According to the EDI3-EDRC scores, 23/77 (29.9%) participants demonstrated positive results in the screening. Participants who had positive results in the screening had significantly higher scores on trait and state anxiety, depression, and IU, and lower means of self-esteem and SD. The SEM demonstrated good fit indices and all paths were significant in the predicted directions, confirming the hypothesized model.
The current results confirm the role of self-esteem and SD in the development of an ED among adolescent females through the mediating action of IU, anxiety, and depression.
低自尊和低自我导向性被认为是饮食失调（ED）发生的一个风险因素。本研究的目的是检验以下假设：低自尊和低自我导向性通过焦虑和抑郁的中介作用导致饮食失调的风险更高。
77名青少年女性回答了饮食失调量表3（EDI - 3）、不确定性不耐受量表（IUS）、气质与性格问卷修订版（TCI - R）、罗森伯格自尊量表（RSES）、状态与特质焦虑量表（STAI）以及症状自评量表90修订版（SCL - 90 - R）。为检验该假设，使用了结构方程模型（SEM）。
根据EDI3 - EDRC评分，23/77（29.9%）的参与者在筛查中显示出阳性结果。筛查结果为阳性的参与者在特质焦虑、状态焦虑、抑郁和不确定性不耐受方面的得分显著更高，而自尊和自我导向性的均值更低。结构方程模型显示出良好的拟合指数，并且所有路径在预测方向上均具有显著性，证实了假设模型。
当前结果通过不确定性不耐受、焦虑和抑郁的中介作用，证实了自尊和自我导向性在青少年女性饮食失调发展中的作用。
