“…It measures appetite for, rather than consumption of, palatable foods, at three levels of food proximity (food available, food present and food tasted). The Yale Food Addiction Scale Version 2.096 reflects the current diagnostic understanding of addiction to further investigate the potential role of an addictive process in problematic eating behaviour 75 97–101.

Combining cognitive bias modification training (CBM) and transcranial direct current stimulation (tDCS) to treat binge eating disorder: study protocol of a randomised controlled feasibility trial

IntroductionBinge eating disorder (BED) is a common mental disorder, closely associated with obesity. Existing treatments are only moderately effective with high relapse rates, necessitating novel interventions. This paper describes the rationale for, and protocol of, a feasibility randomised controlled trial (RCT), evaluating the combination of transcranial direct current stimulation (tDCS) and a computerised cognitive training, namely approach bias modification training (ABM), in patients with BED who are overweight or obese. The aim of this trial is to obtain information that will guide decision-making and protocol development in relation to a future large-scale RCT of combined tDCS+ABM treatment in this group of patients, and also to assess the preliminary efficacy of this intervention.Methods and analysis66 participants with Diagnostic and Statistical Manual-5 diagnosis of BED and a body mass index (BMI) of ≥25 kg/m2 will be randomly allocated to one of three groups: ABM+real tDCS; ABM+sham tDCS or a wait-list control group. Participants in both intervention groups will receive six sessions of ABM+real/sham tDCS over 3 weeks; engaging in the ABM task while simultaneously receiving bilateral tDCS to the dorsolateral prefrontal cortex. ABM is based on an implicit learning paradigm in which participants are trained to enact an avoidance behaviour in response to visual food cues. Assessments will be conducted at baseline, post-treatment (3 weeks) and follow-up (7 weeks post-randomisation). Feasibility outcomes assess recruitment and retention rates, acceptability of random allocation, blinding success (allocation concealment), completion of treatment sessions and research assessments. Other outcomes include eating disorder psychopathology and related neurocognitive outcomes (ie, delay of gratification and inhibitory control), BMI, other psychopathology (ie, mood), approach bias towards food and surrogate endpoints (ie, food cue reactivity, trait food craving and food intake).Ethics and disseminationThis study has been approved by the North West-Liverpool East Research Ethics Committee. Results will be published in peer-reviewed journals.Trial registration number ISRCTN35717198

“…A better understanding of the relationship between FA, NSSI, and emotion regulation is essential for a more comprehensive understanding of risk factors for both FA and NSSI. Previously established associations between NSSI and binge‐type ED, increased exhibition of dysregulated behaviour among individuals with NSSI and ED and an overlap between FA and binge‐type disorders are indicative of several overlaps across behaviours (Gearhardt et al, ; Islam et al, ; Steward et al, ; Vieira et al, ; Wolz et al, ). Furthermore, emotion dysregulation can be considered as a common trait among individuals with NSSI and FA (Muehlenkamp et al, ; Wolz et al, ; Yurkowski et al, ).…”

Objective We examined the association between lifetime nonsuicidal self‐injury (NSSI), emotion regulation, and food addiction (FA) in women (n = 220) with eating disorders (ED) compared with (n = 121) healthy controls (HC). Method Participants were assessed via face‐to‐face interviews for ED diagnosis and lifetime NSSI. FA was assessed with Yale Food Addiction Scale 2.0 and emotion regulation using the Difficulty in Emotion Regulation Scale (DERS). Results The prevalence of FA was significantly higher among women with an ED when compared with HC (75.9% vs. 4.1%, p < 0.001). Similarly, subjects presenting FA showed a high prevalence of lifetime NSSI, in both ED and HC (40.7% and 60.0%, respectively). Our predictive model revealed FA and DERS total scores as indicators of the presence of lifetime NSSI independent of group assignment, ED diagnosis, and age. Conclusions These findings suggest a shared aetiology between ED, NSSI, and FA, explained possibly in part by emotion‐regulation deficits.

“…Considering the literature, published so far, FA is frequently associated with higher ED severity and more general psychopathology (Granero et al, ; Granero et al, ; Piccinni, Marazziti, Cargioli, Mauri, & Stallone, ), but also with more dysfunctional personality traits, namely negative urgency and impulsivity (Wolz et al, , ; Ouellette et al, ). Furthermore, several recent studies have found positive association of FA with neuropsychological impairments, namely decision making and attentional bias to food (Aviram‐Friedman, Astbury, Ochner, Contento, & Geliebter, ; Steward et al, ). Among the different disorders, FA seems to reflect a transdiagnostic condition (Granero et al, ; Jiménez‐Murcia et al, ; Piccinni et al, ).…”
