“…In addition, women who reported higher overall (i.e., between‐person) expectancies that eating would improve their mood engaged in more binge eating across EMA. This is consistent with previous research that has identified affect regulation eating expectancies as an important trait‐based factor associated with binge eating (Smith, Mason, Peterson, & Pearson, ). This is also important in light of recent theoretical work suggesting transitions from emotionally‐driven to habit‐based binge eating (Pearson, Wonderlich, & Smith, ).…”

Objective: Affect regulation, eating expectancies, and attention toward food-related cues are interrelated constructs that have been implicated in the maintenance of binge eating. While these processes show considerable temporal variability, the momentary associations between these domains have not been elucidated. This study examined a model that posited momentary fluctuations in affect, eating expectancies, and attention bias (AB) would interact to predict subsequent binge eating.Method: Forty women who endorsed recurrent binge eating completed a 10-day ecological momentary assessment protocol with ambulatory measures of AB (i.e., dot-probe task with palatable food and neutral cues) and self-report assessments of positive and negative affect, eating expectancies (i.e., the belief that eating would improve one's mood), and binge-eating symptoms.Results: Generalized linear mixed models indicated higher momentary AB toward palatable food was associated with increased risk of subsequent binge eating, and a two-way interaction showed that moments of higher eating expectancies and negative affect were associated with increased likelihood of subsequent binge eating. Also, a three-way interaction emerged, in that the association between eating expectancies and subsequent binge eating was strongest at lower levels of positive affect and higher AB.Discussion: Together, findings partially supported hypotheses and demonstrate meaningful within-person fluctuations in AB that precede binge eating. Further, results demonstrate that the momentary influence of eating expectancies on binge eating depends on both affective state and attentional processes.

“…Our finding of an association of greater anticipatory caudate response with elevated harm avoidance (e.g., anxiety) in RBN is consistent with this notion and adds to a growing body of evidence linking negative affect with increased caudate anticipatory reward response in BN, perhaps providing a mechanism for behavioral findings that bulimic episodes are often preceded by and planned in the context of negative affect and emotional instability [96][97][98] . In fact, several studies have found direct associations between caudate function/structure and clinical symptoms in BN, including negative affect 21 , craving 99 , and self-induced vomiting frequency 92 .…”

Increased anticipatory brain response to pleasant touch in women remitted from bulimia nervosa

Bulimia nervosa (BN) is characterized by affective instability and dysregulated behaviors (binge eating, fasting, selfinduced vomiting) that disrupt bodily homeostasis. Mechanisms underlying dysregulation in BN are unclear, although altered reward responsivity, anticipatory processing of environmental cues, and interoception (detection and integration of body-state signals to regulate behavior) have been implicated in BN pathophysiology. We aimed to determine whether BN is associated with ineffectively predicting body state or integrating predicted experience with actual experience by examining neural response to anticipation and experience of affective touch, a pleasant interoceptive stimulus that acts on sensory and emotional systems to guide behavior. During fMRI, we administered soft strokes to the palm and forearm in women remitted from BN (RBN; N = 23) and control women (CW; N = 25). A Group (RBN/CW) × Condition (anticipation/touch) interaction was found in the right dorsal caudate; both CW and RBN had increased activation during touch compared with anticipation, with RBN demonstrating marginally greater anticipatory response than CW. For RBN, those individuals who showed greater anticipatory response in the dorsal caudate also reported higher levels of harm avoidance. RBN individuals relative to CW showed greater activation in left putamen and insula during the anticipation but not when experiencing an affective touch. This increase during anticipation rather than the actual experience of the affective touch is consistent with a top-down preparatory process which is associated with harm avoidance and is similar to what has been observed in anxious individuals. This aberrant signal integration could disrupt feedback processing, serving to maintain disordered behavior.

“…As EE and obesity have consistently been associated with higher sensitivity to reward (Davis et al, ; Davis et al, ), reward sensitivity should also be taken into account. For instance, Smith, Mason, Peterson, and Pearson () found that the association between emotion dysregulation and BE frequency was mediated by eating expectancies (i.e., eating will help alleviate negative affect) among individuals with high level of anticipatory reward, whereas this model was insignificant among individuals with low anticipatory reward. Thus, the interaction between reward sensitivity and ER difficulties could especially be of interest among individuals with negative as well as positive EE.…”

Objective We aimed to investigate the phenotypes of individuals with emotional eating (EE) based on their levels of positive and negative EE, body mass index (BMI), and preoccupation with weight, and to assess differences in eating pathology and emotion regulation (ER) difficulties among them. Method A community sample of 605 women (mean age = 29.8 years, SD = 9.6; mean BMI = 23.4 kg/m2, SD = 4.7) filled out the Positive–Negative Emotional Eating Scale, Eating Disorders Assessment Scale, and Difficulties in Emotion Regulation Scale. Data of BMI, positive EE, negative EE, and preoccupation with body weight were submitted to a latent profile analysis. Results A four‐profile model was discovered with normal weight individuals without EE (63%), normal weight individuals with EE (23%), overweight individuals without EE (9%), and obese individuals with EE (5%). A five‐profile model was also included, as a class of normal weight individuals with positive EE was found. Obese and normal weight individuals with EE showed the highest level of ER difficulties and eating pathology. Overweight individuals without EE showed moderate levels of eating pathology and low levels of ER difficulties, suggesting that high BMI itself might not be related to eating disorder (ED) psychopathology. Normal weight individuals with positive EE showed low levels of eating pathology, but moderate levels of ER difficulties. Discussion Our results suggest that negative EE could be an important risk factor for disordered eating, independent of BMI. Further, individuals with EE could benefit from learning adaptive ER strategies to prevent the onset or maintenance of ED or weight gain.
