Eating Psychology: The Role of Nature and Nurture<br />
Racine, S. E., Keel, P. K., Burt, S. A., Sisk, C. L., Neale, M., Boker, S., & Klump, K. L. (2013). Exploring the<br />
relationship between negative urgency and dysregulated eating: Etiologic associations and the role of negative<br />
affect. Journal of Abnormal Psychology, 122(2), 433.<br />
Negative urgency is the tendency to engage in rash action in response to negative affect, which contributes to<br />
individual differences and personality traits involved in the psychology of eating. The present study examined the<br />
genetic and environment associations with dysregulated eating (binge eating, emotional eating, etc.) and established the<br />
relationship between negative urgency and negative affect. In a sample of 222 same-sex female twin pairs from the<br />
Michigan State University Twin Registry, genetic factors accounted for the phenotypic association found between<br />
negative urgency and dysregulated eating (62-77%). Negative affect and negative urgency covaried significantly and<br />
was controlled for in the previous analyses. On the other hand, non-shared environmental factors accounted for the rest<br />
of the association (23-38%). Interestingly, the non-shared environmental factors were unrelated to negative affect. The<br />
authors conclude that emotionally based actions (i.e., negative urgency) coupled with negative affect increased genetic<br />
risk associated with dysregulated eating. As such, this study showed that mood and genetic factors play roles in the<br />
psychology of eating.<br />
