Genetic and environmental factors underlying relationships between personality traits and disordered eating were examined in 256 female adolescent twin pairs (166 monozygotic, 90 dizygotic). Eating behaviors were assessed with the Total Score, Body Dissatisfaction, Weight Preoccupation, Binge Eating, and Compensatory Behavior subscales from the Minnesota Eating Disorders Inventory (M-EDI; K. L. Klump, M. McGue, & W. G. Iacono, 2000). Personality characteristics were assessed with the Negative Emotionality, Positive Emotionality, and Constraint scales from the Multidimensional Personality Questionnaire (MPQ; A. Tellegen, 1982). Model-fitting analyses indicated that although genetic factors were more likely to contribute to MPQ and M-EDI phenotypic associations than environmental factors, shared genetic variance between the 2 phenotypes was limited. MPQ personality characteristics may represent only some of several genetic risk factors for eating pathology.
在256对女性青少年双胞胎（166对同卵双胞胎，90对异卵双胞胎）中，研究了人格特质与饮食失调之间关系的遗传和环境因素。使用明尼苏达饮食失调量表（M-EDI；K.L.克伦普、M.麦圭尔和W.G.艾科诺，2000年）中的总分、身体不满、体重关注、暴饮暴食和补偿行为分量表评估饮食行为。使用多维人格问卷（MPQ；A.泰勒根，1982年）中的消极情绪、积极情绪和约束量表评估人格特征。模型拟合分析表明，尽管遗传因素比环境因素更有可能导致MPQ和M-EDI表型关联，但两种表型之间的共享遗传方差有限。MPQ人格特征可能仅代表饮食病理学若干遗传风险因素中的一部分。
