“…In contrast to the ELOC, the LOCES‐brief demonstrated full MI between men and women, which replicates and extends prior research conducted in community adolescents (Vannucci & Ohannessian, ). Current findings suggest that the LOCES‐brief performs similarly in male and female college students.…”

“…Finally, the 7‐item version provided excellent fit to the data in both samples. For parsimony and consistency with prior research (Vannucci & Ohannessian, ), the LOCES‐brief was examined in subsequent analyses. Factor loadings were high ( r = .47–.81), and internal consistencies were good ( α s = .91–.94) across samples.…”

“…Stefano et al () also found higher LOCES scores among individuals at high‐ compared to low‐risk for ED pathology, suggesting that this measure may discriminate between clinical and non‐clinical samples. Finally, Vannucci and Ohannessian () evaluated the psychometric properties of the LOCES‐brief (7‐item scale) in a community sample of adolescents. Results provided support for the uni‐dimensionality of the LOCES‐brief, MI across gender and weight status, and convergent and discriminant validity.…”

Objective Research evidence supports the clinical significance of subjective feelings of loss of control over eating; however, limited attention has been given to how this construct is assessed. Two measures have been developed in recent years (i.e., Eating Loss of Control Scale [ELOC] and Loss of Control over Eating Scale [LOCES]), but further validation in clinical and non‐clinical samples is needed. Method The current study evaluated the psychometric properties, including factor structure, criterion validity, and measurement invariance of the ELOC and LOCES across two groups: (a) a clinical sample of individuals with eating disorders (n = 106) and (b) a non‐clinical sample of college students (n = 321). Results Confirmatory factor analyses indicated that the 16‐item version of the ELOC and 7‐item brief version of the LOCES provided good fit to the data in both samples. These measures were highly correlated (r = .83–.87) and associated with binge‐eating and related psychopathology. The ELOC demonstrated partial invariance between men and women and between the clinical and non‐clinical samples. The LOCES‐brief demonstrated full invariance between men and women and partial invariance between the clinical and non‐clinical samples. Discussion Findings suggest that the 16‐item ELOC and 7‐item LOCES are reliable measures of severity of loss of control eating in clinical and non‐clinical samples. Given the brevity of the LOCES‐brief and evidence for measurement invariance across sex, it is recommended over the ELOC in heterogeneous samples. Future research is needed to confirm the validity of these measures across individuals with and without eating disorders.

“…In addition to including information from other important socializing agents, other types of eating behaviors could be considered as well. For instance, examining more disruptive eating behaviors, such as food addiction and loss of control while eating, could be of high relevance in adolescence [54][55][56]. Another limitation of this study is its cross-sectional design, which limits us from drawing conclusions about the direction and causality of the associations found.…”

Both mothers’ and best friends’ food intake are associated with adolescents’ food intake, but they are rarely investigated simultaneously. In this study, we tested the associations of mothers’ and best friends’ food intake with adolescents’ intake of unhealthy and healthy food, obtained from home and from outside the home, and the moderating role of adolescents’ exposure to their food intake. Participants included 667 adolescents (53% female, Mage = 12.9) and 396 of their mothers. Within this adolescent sample, 378 best friend dyads were identified. All participants completed food frequency questionnaires. Mothers separately reported on their food intake in the presence and absence of their child, and adolescents indicated how often they ate and drank together with their best friend during school breaks. Mothers’, but not best friends’, food intake was positively related to adolescents’ intake of unhealthy and healthy food obtained from home and healthy food obtained from outside the home. Exposure to mothers’ healthy food intake magnified mother-child similarities in healthy food intake. Exposure to best friends’ intake of unhealthy food moderated adolescent-friend similarities in unhealthy food intake. Future work should assess the mechanisms that underlie these similarities, and should investigate these associations over time and in later developmental periods.

“…Of note, previous studies have suggested that subjective binge episodes are clinically meaningful, but have low reliability [ 25 – 27 ]. Improved diagnostic guidelines, assessment tool instructions, and new measures (e.g., the Eating Loss of Control Scale and the Loss of Control over Eating Scale) may help increase reliability and improve diagnosis and severity assessment across disorders characterized by binge eating [ 10 , 11 , 28 , 29 ]. Our findings could help inform the refinement of these assessment tools to measure LOC.…”

Patient descriptions of loss of control and eating episode size interact to influence expert diagnosis of ICD-11 binge-eating disorder

et al. 2020

Background Although data suggest that the sense of “loss of control” (LOC) is the most salient aspect of binge eating, the definition of LOC varies widely across eating disorder assessments. The WHO ICD-11 diagnostic guidelines for binge eating do not require an objectively large amount of food, which makes accurate LOC diagnosis even more critical. However, it can be especially challenging to assess LOC in the context of elevated weight status and in the absence of compensatory behaviors. This ICD-11 field sub-study examined how descriptions of subjective experience during distressing eating episodes, in combination with different eating episode sizes, influence diagnoses of binge-eating disorder (BED). Method Mental health professionals with eating disorder expertise from WHO’s Global Clinical Practice Network (N = 192) participated in English, Japanese, and Spanish. Participants were asked to select the correct diagnosis for two randomly assigned case vignettes and to rate the clinical importance and ease of use of each BED diagnostic guideline. Results The presence of LOC interacted with episode size to predict whether a correct diagnostic conclusion was reached. If the amount consumed during a typical distressing eating episode was only subjectively large compared to objectively large, clinicians were 23.1 times more likely to miss BED than to correctly diagnose it, and they were 9.7 times more likely to incorrectly diagnose something else than to correctly diagnose BED. In addition, clinicians were 10.8 times more likely to make a false positive diagnosis of BED when no LOC was described if the episode was objectively large. Descriptions of LOC that were reliably associated with correct diagnoses across episodes sizes included two that are similar to those already included in proposed ICD-11 guidelines and a third that is not. This third description of LOC focuses on giving up attempts to control eating because perceived overeating feels inevitable. Conclusions Results highlight the importance of detailed clarification of the LOC construct in future guidelines. Explicitly distinguishing LOC from distressing and mindless overeating could help promote consistent and accurate diagnosis of BED versus another or no eating disorder.
