An estimated 3.3 million people die from eating disorders (EDs) annually, making EDs a universal health crisis. ED rates particularly elevated among college students. Etiological models have consistently highlighted the critical role of emotion regulation (ER) and impulsivity in the development of EDs, which have also become salient treatment targets. While studies have established strong associations between negative ER, impulsivity, and ED symptoms, findings regarding positive-valanced emotional difficulties remain sparse mixed due to the growing body of research and significant variability across studies.
To address this gap, we adopted a transdiagnostic approach to examine the additive and multiplicative associations between valence-specific urgency and ER difficulties in relation to disordered eating behaviors (e.g., fasting, binge eating, purging, and excessive exercise) among college students. In this presentation, we describe:
Our sample consisted of 181 college students with elevated clinical severity, drawn from a larger study investigating the effects of ER difficulties on risky behaviors. Participants completed self-report measures for (1) negative and positive ER difficulties (DERS & P-DERS), (2) negative and positive urgency (UPPS-P), and (3) ED behaviors (e.g., binge eating, purging, fasting, and excessive exercise; EDDS).
Contrary to prior work, our results suggest that positive ER difficulties were significantly associated with binge eating (b = 0.70, p < .001) and fasting frequency (b = 0.69, p = .010) at low levels of positive urgency. Additionally, positive ER difficulties were significantly associated with purging frequency at both low (b = 1.41, p < .001) and high levels of positive urgency (b = 0.72, p < .001). Furthermore, negative ER difficulties were significantly associated with binge eating frequency at low levels of negative urgency (b = 0.51, p < .001).
Investigating these interactive effects provides valuable insight into how positive and negative ER jointly contribute to ED symptomatology. This understanding can inform more effective ED treatments that not only target ER, but also incorporate both positive and negative emotions in the treatment process.
