摘要
Genetic and environmental factors underlying relationships between personality traits and disordered eating were examined in 256 female adolescent twin pairs (166 monozygotic, 9C 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. lacono. 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.
