Eat Weight Disord. 2019 Apr;24(2):313-322. doi: 10.1007/s40519-017-0387-8. Epub 2017 Apr 18.
Disordered eating behaviors are on the rise among youth. The present study investigates psychosocial and weight-related variables as predictors of eating disorders (ED) through disordered eating (DE) dimensions (namely restrained, external, and emotional eating) in Lebanese university students.
The sample consisted of 244 undergraduates (143 female) aged from 18 to 31 years (M = 20.06; SD = 1.67). Using path analysis, two statistical models were built separately with restrained and emotional eating as dependent variables, and all possible direct and indirect pathways were tested for mediating effects. The variables tested for were media influence, perfectionism, trait emotional intelligence, and the Big Five dimensions.
In the first model, media pressure, self-control, and extraversion predicted eating disorders via emotional eating. In the second model, media pressure and perfectionism predicted eating disorders via restrained eating.
Findings from this study provide an understanding of the dynamics between DE, ED, and key personality, emotion-related, and social factors in youth. Lastly, implications and recommendations for future studies are advanced.
青少年中饮食失调行为呈上升趋势。本研究通过黎巴嫩大学生的饮食紊乱（DE）维度（即克制性、外部性和情绪化饮食），调查心理社会因素和体重相关变量作为饮食失调（ED）的预测因素。
样本包括244名年龄在18至31岁之间的本科生（143名女性）（M = 20.06；标准差 = 1.67）。使用路径分析，分别建立了两个统计模型，以克制性饮食和情绪化饮食作为因变量，并测试了所有可能的直接和间接途径的中介效应。所测试的变量包括媒体影响、完美主义、特质情商和大五人格维度。
在第一个模型中，媒体压力、自我控制和外向性通过情绪化饮食预测饮食失调。在第二个模型中，媒体压力和完美主义通过克制性饮食预测饮食失调。
本研究结果有助于理解青少年中饮食紊乱、饮食失调以及关键的人格、情绪相关和社会因素之间的动态关系。最后，提出了对未来研究的启示和建议。
