“…One adult study reported elevated %trunk fat, but not total %body fat or %abdominal fat, in those with LOC relative to those without LOC . Of 11 adult studies directly comparing those with different forms of LOC and/or overeating, six found that OBE, SBE and/or OO did not differ on BMI , while five found that BMI was higher in those with OBE relative to those with SBE . One adult study reported that BMI was correlated with OBE but not OO frequency , while another reported no associations between LOC eating frequency and any anthropometric variables .…”

Background Binge eating is a marker of weight gain and obesity, and a hallmark feature of eating disorders. Yet, its component constructs—overeating and loss of control (LOC) while eating—are poorly understood and difficult to measure. Objective To critically review the human literature concerning the validity of LOC and overeating across the age and weight spectrum. Data sources English-language articles addressing the face, convergent, discriminant, and predictive validity of LOC and overeating were included. Results LOC and overeating appear to have adequate face validity. Emerging evidence supports the convergent and predictive validity of the LOC construct, given its unique cross-sectional and prospective associations with numerous anthropometric, psychosocial, and eating behavior-related factors. Overeating may be best conceptualized as a marker of excess weight status. Limitations Binge eating constructs, particularly in the context of subjectively large episodes, are challenging to measure reliably. Few studies addressed overeating in the absence of LOC, thereby limiting conclusions about the validity of the overeating construct independent of LOC. Additional studies addressing the discriminant validity of both constructs are warranted. Discussion Suggestions for future weight-related research and for appropriately defining binge eating in the eating disorders diagnostic scheme are presented.

“…Although results should be interpreted in light of the small sample used, one might expect that behaviorally-measured impulsivity would relate most closely to overt behavioral outcomes (i.e., binge frequency) rather than to overall pathology. However, recent literature has suggested that illness severity does not necessarily correspond with binge eating size or frequency, but rather perceived loss of control (42). It is possible that impulsivity is associated with loss of control (regardless of frequency of the behavior), and thus in future research it may be beneficial to measure loss of control dimensionally.…”

“…A second counterintuitive finding is the marginally significant negative association between negative urgency and binge eating at baseline. Two potential explanations for this finding are that (1) binge eating frequency (as opposed to another measure, such as dimensional loss of control) may not be a valid proxy for illness severity within a BED sample (42) and (2) that the relation between negative urgency and binge frequency may be different for those who are treatment-seeking. However, future research and replication is necessary to support these claims.…”

Does impulsivity predict outcome in treatment for binge eating disorder? A multimodal investigation

et al. 2016

Multiple dimensions of impulsivity (e.g., affect-driven impulsivity, impulsive inhibition – both general and food-specific, and impulsive decision-making) are associated with binge eating pathology cross-sectionally, yet the literature on whether impulsivity predicts treatment outcome is limited. The present pilot study explored impulsivity-related predictors of 20-week outcome in a small open trial (n=17) of a novel treatment for binge eating disorder. Overall, dimensions of impulsivity related to emotions (i.e., negative urgency) and food cues emerged as predictors of treatment outcomes (i.e., binge eating frequency and global eating pathology as measured by the Eating Disorders Examination), while more general measures of impulsivity were statistically unrelated to global eating pathology or binge frequency. Specifically, those with higher levels of negative urgency at baseline experienced slower and less pronounced benefit from treatment, and those with higher food-specific impulsivity had more severe global eating pathology at baseline that was consistent at post-treatment and follow-up. These preliminary findings suggest that patients high in negative urgency and with poor response inhibition to food cues may benefit from augmentation of existing treatments to achieve optimal outcomes. Future research will benefit from replication with a larger sample, parsing out the role of different dimensions of impulsivity in treatment outcome for eating disorders, and identifying how treatment can be improved to accommodate higher levels of baseline impulsivity.

“…ICD-11 differs in the inclusion of subjective binge eating episodes (SBEs), where the amount consumed is normal or small although subjectively considered as large by the individual. This is supported by a large body of research [ 10 , 11 , 12 , 13 ]. A second point of difference between the DSM-5 and proposed ICD-11 criteria for BN and BED is the duration of binge eating episodes.…”

An Investigation of the Clinical Utility of the Proposed ICD-11 and DSM-5 Diagnostic Schemes for Eating Disorders Characterized by Recurrent Binge Eating in People with a High BMI

The aims of this paper were to compare (1) the proportion of participants diagnosed with threshold or subthreshold Bulimia Nervosa (BN) and Binge Eating Disorder (BED) (clinical utility), and (2) the severity of participants’ clinical features and mental Health-Related Quality of Life (HRQoL) (convergent validity), when diagnosed according to either the Diagnostic and Statistical Manual of Mental Disorders—5th edition (DSM-5) or the proposed International Classification of Diseases 11th edition (ICD-11) schemes. One hundred and seven adult men and women, with a high Body Mass Index (BMI) were evaluated by interview to confirm their eating disorder diagnoses. All participants completed self-report assessments of current symptoms and mental HRQoL. The majority of participants in either diagnostic scheme were included in the main categories of BN or BED (102/107, 95% in the ICD-11 and 85/107, 79% in the DSM-5). Fewer individuals received a subthreshold other or unspecified diagnosis with the ICD-11 compared to the DSM-5 scheme (5% vs. 21%). No significant differences in demographic, clinical features or mental HRQoL of participants with complete or partial BN or BED were found between diagnostic categories. Compared to the DSM-5, the proposed ICD-11 was not over inclusive, i.e., it did not appear to include people with less severe and potentially less clinically relevant symptoms. These results support the greater clinical utility of the ICD-11 whilst both schemes showed convergent validity.

Comparing symptomatic and functional outcomes over 5 years in two nonclinical cohorts characterized by binge eating with and without objectively large episodes

Abstract: Individuals that report regular SBEs without regular OBEs represent a group with similar mental hardship and outcomes to those with regular OBEs. The findings support inclusion of regular SBEs in criteria for eating disorder diagnostic categories characterized by recurrent binge eating.
