Emily Prather Defends Dissertation on Anger and Binge Eating
04/16/15 Anger
Emily Prather successfully defended her doctoral dissertation yesterday at the University of Southern Mississippi, Predictors of Binge Eating in College Women. Emily's study evaluated the relationships among four theoretically relevant factors hypothesized to predict subclinical binge eating in a sample of college women: trait anger, anger suppression, impulsivity, and emotion regulation.
Emily started by confirming the four-factor structure of the UPPS Impulsivity Scale (Whiteside & Lynam, 2001) through confirmatory factor analysis. Multiple measures of impulsivity have been used in the literature, and the UPPS is one of the newer ones. Given that there has been some disagreement over the optimal factor structure, it was important to make sure that the four-factor structure of this measure would be confirmed in this sample. After confirming this factor structure, Emily found that the urgency and lack of perseverance factors predicted binge eating. Urgency was a hypothesized predictor, but the utility of perseverance was unexpected and suggests that the role of impulsivity in binge eating may be somewhat broader than previously thought.
Trait anger predicted binge eating over and above general negative affect, suggesting that there seems to be something about one's propensity to experience angry feelings that may be particularly useful in understanding binge eating. The tendency to suppress anger in an unhealthy manner also predicted binge eating, and both anger suppression and emotion regulation partially mediated the relationship between trait anger and binge eating. It appears that anger management and the development of emotion regulation strategies may be worth exploring for college women with subclinical binge eating.
Emily is currently completing her predoctoral internship at Wellspan Behavioral Health in York, PA. She recently accepted a postdoc position with Wellspan to begin this summer.
Congratulations, Emily!

Predictors of Binge Eating in College Women

Emily Prather proposed her dissertation today, Predictors of Binge Eating in College Women. She did a great job with her proposal, and her dissertation committee approved her plan.
Emily's study aims to clarify the possible roles of trait anger, anger suppression, impulsivity, and emotion regulation in binge eating among college women. Data collection will begin in the fall. It is hoped that her study will inform our understanding of binge eating.

Article on Driving Anger and Boredom Proneness Makes AAP's Top 20 Most Cited List

I was just informed by Elsevier that a 2005 article we published in Accident Analysis and Prevention was one of the top 20 most cited articles from this journal published between 2005 and 2010. The citation of the article is:
Dahlen, E. R., Martin, R. C., Ragan, K., & Kuhlman, M. M. (2005). Driving anger, sensation seeking, impulsiveness, and boredom proneness in the prediction of unsafe driving. Accident Analysis & Prevention, 37(2), 341-348. https://doi.org/10.1016/j.aap.2004.10.006
The study examined the role of impulsivity, sensation seeking, boredom proneness, and driving anger as predictors of aggressive and risky driving in a college student sample. In addition to providing further support for the utility of the Driving Anger Scale (DAS; Deffenbacher et al., 1994) in the assessment of unsafe driving behavior, we found that sensation seeking, boredom proneness, and impulsivity resulted in incremental improvements to the predictive model over and above driving anger. Overall, this helps to strengthen the case for using multiple predictors to understand risky and aggressive driving.
It is great to know that others have found this paper useful in their research.
