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.
目的
本研究检验了青少年前女童饮食失调的风险模型：青春期开始与负面冲动（在困扰时草率行事的人格倾向）的增加有关；负面冲动通过塑造社会心理学习（期望形成）影响饮食失调症状，从而间接影响症状水平；许多与清除有关的影响是由暴食介导的。
方法
905 名五年级女孩完成了饮食失调、负面冲动、节食/消瘦和饮食期望的问卷测量。
结果
五年级女孩存在暴食和清除行为。正如预期的那样，青春期状态与更高水平的负面冲动有关，负面冲动与每个期望衡量标准有关，二次节食/消瘦和饮食期望与暴食有关，暴食与清除有关。
讨论
开发青少年饮食失调行为的风险模型很重要且可行。我们的模型将青春期、个性和社会心理学习结合在一起，似乎很有前途。
