The extant literature indicates negative self-perceptions are a risk factor for disordered eating (DE) and DE is a risk factor for overweight and obesity. While childhood emotional abuse (EA) is often linked to DE and obesity, it is typically not included in comprehensive models of these health problems. Further investigation of interactions among EA, self-perception, and DE is needed to refine treatments for overweight, obesity, and DE. This study evaluated a model of DE and weight difficulties in which negative self-perception mediate the relationship between EA and DE, and DE predicts body mass index (BMI) in a population of emerging adults. Further, this study investigated the utility of history of EA for prediction of DE and classification of individuals with and without DE. Self-report questionnaires on childhood trauma, psychopathology, and eating behaviors were administered to 598 undergraduate students. Latent variable analysis confirmed the hypothesized model. Recursive partitioning determined that individuals reporting a high level of EA likely meet criteria for night eating syndrome (NES) or binge eating disorder (BED), and history of EA has a moderate to high level of specificity as a predictor of BED and NES. These findings confirm the necessity of evaluating EA and DE in emerging adults with weight difficulties, and the importance of assessing self-perception and DE in individuals with a history of EA. Future studies should investigate the utility of addressing EA and self-perception in interventions for DE and obesity and to determine whether these findings can be generalized to a clinical population.
现有文献表明，消极的自我认知是饮食失调（DE）的一个风险因素，而饮食失调是超重和肥胖的一个风险因素。虽然童年期情感虐待（EA）通常与饮食失调和肥胖有关，但它通常不被纳入这些健康问题的综合模型中。需要进一步研究情感虐待、自我认知和饮食失调之间的相互作用，以完善针对超重、肥胖和饮食失调的治疗方法。本研究评估了一个饮食失调和体重问题模型，其中消极的自我认知介导了情感虐待与饮食失调之间的关系，并且饮食失调在一群新兴成年人中预测体重指数（BMI）。此外，本研究调查了情感虐待史在预测饮食失调以及对有或没有饮食失调的个体进行分类方面的效用。对598名本科生进行了关于童年创伤、精神病理学和饮食行为的自我报告问卷调查。潜变量分析证实了假设模型。递归划分确定，报告高水平情感虐待的个体可能符合夜间进食综合征（NES）或暴饮暴食症（BED）的标准，并且情感虐待史作为暴饮暴食症和夜间进食综合征的预测指标具有中度到高度的特异性。这些发现证实了在有体重问题的新兴成年人中评估情感虐待和饮食失调的必要性，以及在有情感虐待史的个体中评估自我认知和饮食失调的重要性。未来的研究应该调查在饮食失调和肥胖干预中解决情感虐待和自我认知问题的效用，并确定这些发现是否可以推广到临床人群。
