“…Second, our large community sample contained a sufficient number of individuals to fully dissociate LOC and OO components of OBEs. Finally, demonstrating elevated NU in non-treatment seeking women with OBEs confirms findings from treatment-seeking samples (8) and is critical, given that maladaptive personality traits are elevated in treatment-seeking compared to non-treatment seeking individuals with eating disorders (22). …”

Objective Negative urgency (NU; tendency to act impulsively when experiencing negative emotions) is a risk factor for binge eating, although few studies have examined interviewer-assessed objective binge episodes (OBEs). Moreover, research has not investigated how NU relates to the core components of OBEs: loss of control (LOC) eating and objective overeating (OO). Understanding the relationship between NU and these core components will enhance etiologic models of eating disorder development. Thus, the current study examined associations between NU, OBEs, and the components of OBEs by comparing levels of NU in women with OBEs, LOC eating only, and OO only to women with no pathological eating. Method Participants were 612 women who endorsed lifetime OBEs (5.4%), LOC eating outside of OBEs (5.7%), OO only (2.8%), or none of these eating episodes (85.9%). Results Women with OBEs, LOC only, and OO only had significantly higher levels of NU than women without these episodes, suggesting that NU is associated with both the LOC and OO components of OBEs. Discussion NU relates to the spectrum of pathology present in women with OBEs. Future research should examine the mechanisms underlying these associations, including impaired behavioral/psychological control and/or increased reward sensitivity in response to negative affect.

“…Treatment seeking individuals with AN may differ from non-treatment seeking samples in important ways, such as reporting higher levels of negative emotionality and stress. 33 It will therefore be important for future research to determine whether the effects observed in this study extend to diverse samples representing the full eating disorder spectrum and to non-treatment seeking samples. Finally, consistent with the majority of prior research (for exception, see Ref.…”

Associations between negative affect and binge/purge behaviors in women with anorexia nervosa: Considering the role of negative urgency

Objective Evidence implicates negative affect in the occurrence of binge/purge behaviors, although the extent to which theoretically relevant individual difference variables may impact this association remains unclear. Negative urgency, the dispositional tendency to engage in rash action when experiencing negative affect, is a unique facet of impulsivity that may play a key role. Moreover, it was hypothesized that women with anorexia nervosa (AN) who are higher on measures of negative urgency, relative to those lower on negative urgency, would exhibit: 1) greater binge eating and purging frequencies on high negative affect days, and 2) a greater change in negative affect prior to and following binge eating and purging episodes. Method Women with AN (n = 82) completed a self-report measure of negative urgency and a 2-week ecological momentary assessment protocol in which they recorded binge eating, purging, and negative affect ratings. Results Women with higher levels of negative urgency exhibited a greater frequency of binge eating and purging; however, in comparison to women low on negative urgency, they: 1) were more likely to binge eat on days corresponding with low-to-moderate negative affect (similar rates of binge eating were observed on high negative affect days), and 2) displayed substantially elevated levels of negative affect across time, and thus, smaller degrees of change in negative affect prior to and following binge eating and purging episodes. Discussion Negative urgency underlies individual differences in the daily experience of negative affect. Women with AN who are high on negative urgency may have an increased propensity for binge eating and purging via a relatively persistent and heightened state of negative emotions.

“…Psychiatric comorbidities may differ between such samples and community samples with the same illness (96). Treatment-seeking ED samples are more likely to have Axis II pathology (97,98), but no research has established differences in Axis I diagnoses. Because the current study examined Axis I, it is unclear how treatmentseeking status affected results.…”

New findings emerged: extremely high comorbidity regardless of eating disorder, ubiquitous depression across all eating disorders, no difference in overall rate of anxiety disorders across eating disorders, greater posttraumatic stress disorder in binge-purge anorexia, more psychotic diagnoses in anorexia. Certain previous findings were confirmed: more obsessive-compulsive disorder in anorexia; more substance use in bulimia; and a replicated comorbidity rank-ordering for eating disorder patients: mood, anxiety, and substance use disorders, respectively.

Abstract: These results suggest that personality deviations may be overestimated in treatment-seeking samples.
