目的：本研究验证了青春期前女孩进食障碍的风险模型：青春期开始与消极紧迫感(痛苦时轻率行事的个性倾向)的增加有关；消极紧迫感通过塑造心理社会学习(期望形成)影响进食障碍症状，从而间接影响症状水平；许多影响通便的因素是通过暴饮暴食来调节的。方法：五年级955名女孩完成了关于进食病理、消极紧迫感、节食/瘦和进食预期的问卷测量。正如预期的那样，青春期状态与较高的负紧迫感水平相关，负紧迫感与每项预期指标相关，二次节食/瘦和饮食期望与暴饮暴食相关，暴饮暴食与呕吐相关。讨论：建立青春期前饮食失调行为的危险模型是重要的和可行的。我们的模型集成了青春期、个性和心理社会学习，看起来很有前途。(C)2010年，威利期刊公司。
Objective: This study tested this risk model for disordered eating in preadolescent girls: pubertal onset is associated with increases in negative urgency (the personality tendency to act rashly when distressed); negative urgency influences eating disorder symptoms by shaping psychosocial learning (expectancy formation), thus indirectly influencing symptom levels; and many influences on purging are mediated by binge eating.Method: Nine hundred five fifth grade girls completed questionnaire measures of eating pathology, negative urgency, and dieting/thinness and eating expectancies.Results: Binge eating and purging behaviors were present in fifth grade girls. As anticipated, pubertal status was associated with higher levels of negative urgency, negative urgency was associated with each expectancy measure, quadratic dieting/thinness and eating expectancies were associated with binge eating, and binge eating was associated with purging.Discussion: It is important and feasible to develop risk models for preadolescent eating disordered behaviors. Our model that integrates puberty, personality, and psychosocial learning appears promising. (C) 2010 by Wiley Periodicals, Inc.
