, 2010; Gratz et al., 2013). This association is also evident on a neurobiological level, as high harm avoidance is related to stronger resting state activation and white matter microstructural organization of brain networks associated with emotion regulation (Taddei et al., 2012; Baeken et al., 2014), and correlates with amygdala activation to emotional images (Most et al., 2006; Baeken et al., 2009; Van Schuerbeek et al., 2014). Furthermore, both high levels of harm avoidance and low levels of self-directedness are associated with lower ��-opioidergic neurotransmission in emotion-related brain regions (which is involved in the modulation of emotional reactions; Tuominen et al., 2012). Overall, this research suggests that certain personality traits may increase the risk for emotion regulation difficulties, which, in turn, may increase the risk for various forms of psychopathology, including ED. Although basic research points to a relation between personality and emotion regulation, there is limited research on the relations between personality and emotion regulation in specific psychiatric disorders. Moreover, most research on the interrelations of personality and emotional functioning in ED has LY2157299 supplier focused on emotional responding vs. emotion regulation per se. For example, one such study (Brownstone et al., 2013) found that the relation between affect lability and over-exercising in BN is moderated by compulsive personality traits. Additionally, there is research on the mediating role of anger in the relation between certain personality traits and ED (Krug et al., 2008; Amianto et al., 2012). Research on the interrelations of personality traits and emotions in ED notwithstanding, a growing body of research emphasizes the importance of considering responses to emotions (i.e., emotion regulation) rather than the nature or quality of emotions per se when examining psychopathology, both in general (e.g., Gratz and Tull, 2010; Gratz et al., 2013) and with regard to ED in particular (Fox and Power, 2009; Evers et al., 2010). This is a particularly understudied area within the ED literature. One frequently used questionnaire to measure emotion regulation is the Difficulties in Emotion Regulation Scale (DERS; Gratz and Roemer, 2004), which is based on the multidimensional conceptualization of emotion regulation as maladaptive ways of responding to emotions, including a lack of awareness, understanding, and acceptance of emotions, difficulties controlling impulsive behaviors and engaging in goal-directed behaviors when experiencing negative emotions, and a lack of access to effective strategies for modulating emotions.
