OBJECTIVE In order to better understand factors motivating eating disorder (ED) behaviors and better identify persons at-risk for these behaviors, we sought to identify which personality domains and facets were associated with behaviors for weight control. METHODS ED behavior information was gathered from the University of North Carolina Alumni Heart Study using the question, "have you ever used any of the following to lose weight?" Respondents endorsed any combination of the following: "Vomiting," "Fasting," "Laxatives," "Excessive physical exercise." Personality was measured using the Revised NEO Personality Inventory (NEO-PI-R). One-way ANOVAs were performed comparing personality domains and facets to reported ED behaviors, computed both as separate behaviors and the number of cumulative behaviors. RESULTS Of 3496 respondents, 9.41% endorsed ever having used at least one ED behavior, with the majority endorsing only a single ED behavior. For both sexes, endorsing greater numbers of ED behaviors was associated with higher scores on Neuroticism and Openness. For women, the strongest associations for behaviors with personality were: excessive exercise with high Impulsiveness; fasting with high Impulsiveness and low Gregariousness; laxative use/purging with high scores on Activity and Feelings. For men, the strongest associations were: excessive exercise with high Impulsiveness; fasting with high Ideas; laxative use/purging with low Modesty. DISCUSSION Data collected from this sample showed a sex-modulated pattern of association between personality domains and facets with ED behaviors. Our findings support that obtaining personality profiles of individuals exhibiting subclinical eating behaviors will enhance our understanding of who is at risk of developing an ED diagnosis.

受过大学教育的样本中自我报告的饮食失调行为和个性的关联

目的 为了更好地了解导致饮食失调 (ED) 行为的因素并更好地识别有这些行为风险的人，我们试图确定哪些人格领域和方面与体重控制行为相关。方法 ED 行为信息是从北卡罗来纳大学校友心脏研究中收集的，使用的问题是“您是否曾经使用以下任何一种方法来减肥？” 受访者赞同以下任意组合：“呕吐”、“禁食”、“泻药”、“过度体育锻炼”。使用修订后的 NEO 个性量表 (NEO-PI-R) 测量个性。进行单向方差分析，将人格领域和方面与报告的 ED 行为进行比较，计算作为单独的行为和累积行为的数量。结果 在 3496 名受访者中，9.41% 的人认可曾经使用过至少一种 ED 行为，大多数人只认可一种 ED 行为。对于两性而言，支持更多 ED 行为与神经质和开放性得分较高有关。对女性而言，行为与性格的最强关联是：过度运动，高冲动；高冲动性和低合群性禁食；泻药使用/清除在活动和感觉上得分高。对于男性来说，最强的关联是：过度运动和高冲动；以崇高的思想禁食；泻药使用/净化低谦虚。讨论 从这个样本中收集的数据显示了人格领域和 ED 行为方面之间的性别调节模式。我们的研究结果支持获得表现出亚临床饮食行为的个体的个性特征将增强我们对谁有发展为 ED 诊断的风险的理解。
