The relationship between gendered racism and binge eating symptoms among young adult U.S. Black women: Identity shifting as a mediator.

Although research has illustrated that racial disparities in access to treatment for binge-eating disorder (BED) among Black women exist, little is known about the psychosocial related experiences of binge eating behaviors among Black women. Binge eating disorder is characterized by the recurrent consumption of large amounts of food within a brief period, accompanied by a loss of sense of control over the eating and distress over the eating behaviors. Past research has shown that race and gender related stressors are positively associated with emotional eating among Black young adult women and that they may engage in problem-solving coping strategies like identity shifting (conscious and unconscious alterations of thoughts, behaviors, perspective, and appearances) to manage these stressors. Considering the literature, the present study was developed to examine the mediating role of identity shifting in the relationship between gendered racism and binge eating symptoms among young adult Black women. To test this assertion, we administered an online survey to 239 Black women (Mage = 27.32). The results indicated that gender racism significantly predicted both identity shifting and binge eating and identity shifting significantly predicted binge eating. Additionally, identity shifting accounted for 34.5 % of the associations between gendered racism and binge eating symptoms. These findings highlight the importance of exploring experiences of discrimination and coping strategies when considering ways to reduce mental health concerns, such as binge eating symptoms, among young adult Black women.

A Brief Online Intervention Based on Dialectical Behavior Therapy for a Reduction in Binge-Eating Symptoms and Eating Pathology.

Dysregulated eating behaviors, comprising subthreshold and clinical binge-eating disorder (BED) and bulimia nervosa (BN), are increasing among the general population, with a consequent negative impact on one's health and well-being. Despite the severity of these outcomes, people with BED and BN often face a delay in receiving a diagnosis or treatment, often due to difficulties in accessing care. Hence, evidence-based and sustainable interventions for eating symptomatology are needed. The present study aims to assess the effectiveness of a web-based 10-session multidisciplinary group intervention based on Dialectical Behavior Therapy (DBT) for BED and BN, aimed at reducing psychological distress and binge-eating-related symptomatology in a sample of patients with dysregulated eating behaviors and including one session of nutritional therapeutic education. A total of 65 participants (84.6% F; age M = 38.5 ± 13.2; experimental group, N = 43; treatment-as-usual group, TAU, N = 22) took part in the study. The results show, after the 9 weekly sessions, a significant reduction in binge-eating-related symptomatology and general psychopathology and an increased self-esteem and eating self-efficacy in social contexts in the experimental group compared to the treatment-as-usual group (T0 vs. T1). Improvements in the experimental group were significantly maintained after one month from the end of the intervention (T2) in terms of binge-eating symptoms, general psychopathology, and eating self-efficacy in social contexts. This study supports the effectiveness of a brief web-based multidisciplinary group intervention in reducing eating symptomatology and psychological distress and enhancing self-esteem and eating self-efficacy in a group of people with dysregulated eating behaviors. Brief web-based interventions could represent an accessible and sustainable resource to address binge-eating-related symptomatology in public clinical settings.

Weight stigma is uniquely tied to maladaptive eating across different racial, ethnic, and gender groups.

Weight stigma, racism, and sexism (social devaluation due to body weight, race or ethnicity, and sex or gender), have been linked to increased maladaptive eating behaviors; however, no research has investigated the unique associations between different forms of stigma and eating concurrently. We analyzed within-group (by race/ethnicity and sex) effects of different forms of stigma on maladaptive eating behaviors to test whether there is some unique relationship between weight stigma and maladaptive eating across identities. Additionally, we explored differences by racial/ethnic group and sex, as well as BMI category, in levels of reported weight stigma, racism, sexism, and maladaptive eating. Participants (N = 1051) were recruited so that there were approximately even numbers of participants identifying as Black (33.3%), Hispanic or Latino (32.8%), and White (33.9%). Overall, participants reported similar amounts of weight stigma by race/ethnicity and sex, but different levels of racism and sexism. Weight stigma, but not racism or sexism consistently predicted binge eating and eating to cope across groups, controlling for education, income, BMI, and age. Restricted dieting, however, was only predicted by weight stigma for Hispanic/Latino and Black men. These findings suggest that weight stigma is a unique predictor of maladaptive eating, even when considering the effects of racism and sexism. This study provides evidence of a more focused model of weight stigma and eating outcomes, rather than a more general model of the effect of stigma on eating outcomes due to overall stress. Future research should investigate when and why weight stigma drives restricted dieting, since this relationship seems strongest in men, going against many common inclinations about weight stigma.

Loneliness as a moderator of the association of affective symptoms and binge eating among college women.

Affective symptoms (e.g., depression, anxiety, shame) are a potent risk factor for binge eating. However, less is known on the role of loneliness as a moderator of affective symptoms and binge eating. This objective of the current study was to investigate main effects and interactions of affective symptoms and loneliness in relation to binge eating in college women. A sample of 556 undergraduate women completed self-report questionnaires of affective symptoms, loneliness, and binge eating. Results revealed significant interactions between each affective symptom variable and loneliness in relation to binge eating, such that loneliness strengthened the positive association of affective symptoms and greater binge eating. The findings of this study demonstrate an important role of loneliness to binge eating among college women, especially those with underlying affective vulnerabilities. More theoretical and treatment-oriented work on the role of loneliness in binge eating is needed to understand mechanisms and interventions/preventions.

Association of body mass index with progression from binge-eating behavior into binge-eating disorder among adolescents in the United States: A prospective analysis of pooled data.

The association between body mass index (BMI) and binge-eating disorder (BED) is well-established. However, data on the extent to which BMI is associated with progression from binge-eating behavior into BED among adolescents are limited, which was the aim of this investigation. Participants were 9964 U.S. adolescents from the Adolescent Brain Cognitive Development (ABCD) Study, aged 9-13 at the time of study enrollment. A computerized parent-reported assessment was used to establish adolescents' binge-eating behaviors and BED. Cox proportional hazards models adjusting for sociodemographic covariates were used to examine prospective associations between BMI and likelihood of BED onset among a) adolescents with binge-eating behavior, and b) adolescents with no binge-eating behavior. Of 975 adolescents who met the study criteria for binge-eating behavior, 89 (9.1%) subsequently met the study criteria for BED. Of 8989 adolescents with no binge-eating behavior, 82 (0.9%) subsequently met the study criteria for BED. BMI percentile was significantly associated with the likelihood of BED onset in participants with (adjusted HR = 1.03, 95% confidence interval [CI] 1.00, 1.06) and participants without (adjusted HR = 1.05, 95% CI 1.03, 1.07) binge-eating behavior. Results were also significant when examining BMI as a dichotomous predictor (above and below 85th percentile) among those with (adjusted HR = 2.60, 95% CI 1.00, 6.68) and those without (adjusted HR = 6.01, 95% CI 3.90, 11.10) binge-eating behavior. Overall, results indicate that elevated BMI is prospectively associated with a greater risk for BED onset among U.S. adolescents with or without binge-eating behavior. Adolescents with a higher BMI may benefit from screening for binge eating, and prevention/early intervention strategies to mitigate the risk for developing BED.

Increased Depressive-like, Anxiety-like, and Perseverative-like Behavior in Binge Eating Model in Juvenile Rats.

The aim of the present study was to evaluate depressive-like, anxiety-like, and perseverative-like behaviors in a binge eating model. Juvenile Wistar rats, using the binge eating model, were compared to caloric restriction, induced stress, and control groups. Rats of the induced stress group presented binge-like behaviors in standard food intake in the second cycle of the experiment when compared to the caloric restriction group and the binge eating model group. Depressive-like behavior was observed in the binge eating model group with longer immobility time (p < 0.001) and less swim time (p < 0.001) in comparison to the control group. Anxiety-like behavior was observed by shorter duration of burying latency in the binge eating model group when compared to the induced stress group (p = 0.04) and a longer duration of burying time when compared to the control group (p = 0.02). We observed perseverative-like behavior by the binge model group, who made more entries to the new arm (p = 0.0004) and spent a longer time in the new arm when compared to the control group (p = 0.0001). Our results show differences in behaviors between the groups of rats studied. These results suggest that calorie restriction-refeeding, along with stress, may lead to depressive-like, anxiety-like, and perseverative-like behavioral changes in male Wistar rats.

Long-term changes in eating-related problems and quality of life in children with overweight and obesity attending a 10-week lifestyle camp.

BACKGROUND: Eating-related problems (e.g., binge eating (BE)) and impaired quality of life (QoL) is more prevalent in children with overweight and obesity. This study aimed to investigate changes in self-reported overeating (OE), BE, and QoL in children with overweight or obesity attending multicomponent 10-week lifestyle camps with a 52-weeks follow-up. Additionally, the study sought to investigate whether self-reported OE/BE before camp was associated with changes in QoL. METHODS: Children aged 7 to 14-years could attend camp if they had overweight/obesity, were lonely, unhappy, or had social or family-related problems. In this study only children with overweight and obesity were included (n:185). OE, BE, and QoL were measured using self-reported questionnaires. RESULTS: In total, 38 % of the children reported regular BE at baseline. Regular OE, occasional BE, and occasional OE was reported by 14 %, 13 %, and 11 %, respectively, while 24 % reported no eating-related problems. The relative risk of experiencing eating-related problems decreased at 10-weeks compared to baseline. Additionally, the probability of regular OE (RR 0.12 (95 % CI 0.04;0.38) (X2 = 8.44, p = 0.004)) and regular BE (RR 0.01 (95 % CI 0.00;0.11) (X2 = 9.91, p = 0.002)) remained lower at 52-weeks relative to baseline. All QoL dimensions improved after camp, and the presence of self-reported OE and regular BE at baseline was significantly associated with lower QoL at baseline, 10 and 52-weeks. CONCLUSION: Children self-reporting OE and BE may be a particular vulnerable group that needs more support from camp staff and healthcare professionals to improve QoL.

Sexual orientation moderates the relationship between internalized weight bias and binge eating symptoms among adults pursuing bariatric surgery.

BACKGROUND: Sexual minorities have higher rates of anxiety, depression, and binge eating compared to heterosexual peers. Internalized weight bias (IWB) is also higher for sexual minorities when compared to heterosexual peers. However, research has not examined whether the relationships between IWB and anxiety, depression, and binge eating differ among heterosexual and sexual minority adults pursuing bariatric surgery. OBJECTIVES: To examine whether sexual orientation (heterosexual or sexual minority) moderated the relationships between IWB and anxiety, depression, and binge eating among adults pursuing bariatric surgery. SETTING: University hospital, United States METHODS: Participants included 811 adults who presented for bariatric surgery, 45 (5.5%) of which identified as a sexual minority. Self-reported data were collected as part of a standard preoperative psychological evaluation for surgical clearance. Three separate moderation models were run to test hypotheses. RESULTS: Sexual orientation did not moderate the association of IWB with anxiety or depression. The IWB by sexual orientation interaction was significant for binge eating (F 1856) = 4.84, P = .03, R2 = .27 such that the association between IWB and binge eating was significantly stronger for sexual minority patients (b = .54, 95% confidence interval {CI} [.36, .70]), compared to heterosexual patients (b = .33, 95% CI [.30, .38]). CONCLUSIONS: Minority stress from identifying as a sexual minority may increase vulnerability to binge eating from IWB among bariatric candidates. Future research examining the directionality of the relationship between IWB and binge eating among sexual minorities is warranted.

Examining neural responses to anticipating or receiving monetary rewards and the development of binge eating in youth. A registered report using data from the Adolescent Brain Cognitive Development (ABCD) study.

Binge eating is characterized as eating a large amount of food and feeling a loss of control while eating. However, the neurobiological mechanisms associated with the onset and maintenance of binge eating are largely unknown. Recent neuroimaging work has suggested that increased responsivity within reward regions of the brain to the anticipation or receipt of rewards is related to binge eating; however, limited longitudinal data has precluded understanding of the role of reward responsivity in the development of binge eating. The current study used data from the Adolescent Brain and Cognitive Development® (ABCD) longitudinal study dataset to assess whether heightened neural responses to different phases of reward processing (reward anticipation and receipt) (1) differentiated individuals with binge eating from matched controls, and (2) predicted the onset of binge eating in an "at risk" sample. Consistent with hypotheses, heightened neural responsivity in the right caudate and bilateral VS during reward anticipation differentiated youth with and without binge eating. Moreover, greater VS response to reward anticipation predicted binge eating two years later. Neural responses to reward receipt also were consistent with hypotheses, such that heightened VS and OFC responses differentiated youth with and without binge eating and predicted the presence of binge eating two years later. Findings from the current study suggest that hypersensitivity to rewards may contribute to the development of binge eating during early adolescence.

Influence of mental and behavioral factors on weight loss after bariatric surgery: A systematic review and meta-analysis.

INTRODUCTION: Multiple factors are related to lower weight loss after bariatric surgery. This review and meta-analysis evaluates the influence of several mental and behavioral factors on weight loss. METHOD: Six electronic databases were searched. Percentage excess weight loss (%EWL) was calculated for all moderator and non-moderator groups of the variables: symptoms of depression, anxiety and binge eating, compliance, physical activity, quality of life, and body image. All moderators, surgery types, and follow-up moments were analyzed separately. RESULTS: In total, 75 articles were included in the review; 12 meta-analyses were conducted. Higher postoperative compliance to follow-up was associated with 6.86%-13.68% higher EWL. Preoperative binge eating was related to more weight loss at 24- and 36-month follow-up (7.97% and 11.79%EWL, respectively). Patients with postoperative binge eating symptoms had an 11.92% lower EWL. Patients with preoperative depressive symptoms lost equal weight compared to patients without symptoms. CONCLUSION: Despite the high heterogeneity between studies, a trend emerges suggesting that the presence of postoperative binge eating symptoms and lower postoperative compliance may be associated with less weight loss after bariatric-metabolic surgery. Additionally, preoperative depressive symptoms and binge eating do not seem to significantly impact weight loss.

Associations between affect dynamics and eating regulation in daily life: a preliminary ecological momentary assessment study.

Disordered eating behaviors consistently associated with emotion regulation difficulties. However, most studies have focused on affect intensity without considering dynamic affective patterns. We examined these patterns in relation to daily overeating, loss of control eating (LOCE), dietary restraint, and food craving in young adults using ecological momentary assessment (EMA).Adults (N = 24) completed a 10-day EMA protocol during which they reported momentary affect and eating patterns. Generalized linear mixed-models examined each index in relation to eating variable.Higher PA instability (within-person) was associated with higher ratings of binge-eating symptoms (B = 0.15, SE = 0.06, p = 0.007). Lower NA differentiation (within-person) was associated with higher levels of food craving (B = -10.11, SE = 4.74, p = 0.033).Our results support previous findings suggesting that acute fluctuations in PA may increase risk of binge-eating symptoms. Further, inability to differentiate between momentary states of NA was associated with cravings. This study highlights the importance of examining multiple facets of NA and PA in relation to eating regulation.Trial registration: ClinicalTrials.gov identifier: NCT02945475.

Momentary appearance focused self-concept is associated with dietary restraint and binge eating in female university students: An experience sampling study.

OBJECTIVE: Appearance focused self-concept (i.e., overvaluing the importance of appearance for self-definition and self-worth) is theorized to predict dietary restraint and binge eating in the short-term (e.g., daily life). Yet, no research has examined whether appearance focused self-concept increases within-persons during a day and if such increases are linked to greater dietary restraint and binge eating for that day. We addressed this gap in knowledge. METHOD: Sixty-three female university students completed four items from the Beliefs About Appearance Scale as a measure of appearance focused self-concept six times per day (9 am, 11 am, 1 pm, 3 pm, 5 pm, and 7 pm) for 14 days. Daily at 9 pm, they completed measures of dietary restraint and binge eating for that day. RESULTS: Analyzing data from 555 days, latent growth curve analyses revealed a small-to-moderate linear increase in appearance focused self-concept from 9 am to 3 pm that plateaued from 3 to 7 pm. A more rapid linear increase in appearance focused self-concept from 9 am to 3 pm was associated with greater binge-eating frequency during that day, but not with dietary restraint. The findings were observed when adjusting for between-day appearance focused self-concept at 9 am, which was positively associated with dietary restraint and binge-eating frequency. DISCUSSION: Findings are discussed in relation to research on appearance focused self-concept as a risk factor for disordered eating. Findings are also discussed in relation to how sociocultural factors may increase appearance focused self-concept over time. Future research should delve into the within-day dynamic interplay between appearance focused self-concept and disordered eating. PUBLIC SIGNIFICANCE: Our study revealed a noteworthy increase in the importance women attach to their appearance over the course of a day, correlating with increased binge eating during that day. Additionally, heightened appearance importance at the onset of a day was associated with more dietary restraint and binge eating during that day. These findings suggest a shorter timescale for the connection between appearance importance and disordered eating than previously understood.

Exploring relationships among appetitive traits, negative affect, and binge eating in adults with overweight or obesity.

Binge eating (BE) is a significant public health concern due to its prevalence and impact on mental and physical health. While research has suggested both negative affect and appetitive traits are associated with BE, few studies have investigated these constructs concurrently. Structural equation modeling (SEM) evaluated relationships between negative affect, reward-related appetitive traits, and BE among 293 adults with overweight or obesity (OW/OB) seeking treatment for BE, overeating, and weight management (m age = 46.6; m body mass index[BMI] = 34.5; 81.2 % female; 20.1 % Latinx, 60.8 % White non-Latinx). BE was related to negative affect (ß = 0.53; p < 0.01) and appetitive traits (ß = 1.53; p < 0.001). Negative affect and appetitive traits were related to one another (r = 0.42; p < 0.001), and the full model accounted for 77 % of the variance in BE. In an exploratory follow-up analysis, multigroup SEM evaluated the above relationships in models stratified by sex. Exploratory findings demonstrated both negative affect and appetitive traits were related to BE across sex, particularly when examining BE cognitions and behaviors. However, relationships in men depended upon BE assessment tool. These findings highlight that both negative affect and appetitive traits are related to BE, and jointly may represent significant risk and maintenance factors, particularly in adults with OW/OB. Our findings also highlight the importance of future investigation of sex differences in BE and the potential impact of assessment method.

Profiles of disordered eating behaviour in type 1 diabetes using the DEPS-R and behaviour and glycaemic outcomes in a real-life setting.

AIMS: The Diabetes Eating Problems Survey - Revised (DEPS-R) is commonly used to assess disordered eating behaviour (DEB) in individuals with type 1 diabetes and has advantages compared to other measures not specifically tailored to diabetes. A score ≥20 on the DEPS-R is used to indicate clinically significant DEB; however, it does not distinguish between eating disorder (ED) phenotypes necessary to guide treatment decisions, limiting clinical utility. METHODS: The current study used latent class analysis to identify distinct person-centred profiles of DEB in adults with type 1 diabetes using the DEPS-R. Analysis of Variance with Games Howell post-hoc comparisons was then conducted to examine the correspondence between the profiles and binge eating, insulin restriction and glycaemic control (HbA1c, mean blood glucose, and percent time spent in hyperglycaemia) during 3 days of assessment in a real-life setting. RESULTS: Latent class analysis indicated a 4-class solution, with patterns of item endorsement suggesting the following profiles: Bulimia, Binge Eating, Overeating and Low Pathology. Differences in binge eating, insulin restriction and glycaemic control were observed between profiles during 3 days of at-home assessment. The Bulimia profile was associated with highest HbA1c and 3-day mean blood glucose. CONCLUSIONS: There are common patterns of responses on the DEPS-R that appear to reflect different ED phenotypes. Profiles based on the DEPS-R corresponded with behaviour in the real-life setting as expected and were associated with different glycaemic outcomes. Results may have implications for the use of the DEPS-R in research and clinical settings.

Effects of Mindful Eating in Patients with Obesity and Binge Eating Disorder.

INTRODUCTION: Binge eating disorder (BED) is a psychiatric illness related to a high frequency of episodes of binge eating, loss of control, body image dissatisfaction, and suffering caused by overeating. It is estimated that 30% of patients with BED are affected by obesity. "Mindful eating" (ME) is a promising new eating technique that can improve self-control and good food choices, helping to increase awareness about the triggers of binge eating episodes and intuitive eating training. OBJECTIVES: To analyze the impact of ME on episodes of binge eating, body image dissatisfaction, quality of life, eating habits, and anthropometric data [weight, Body Mass Index (BMI), and waist circumference] in patients with obesity and BED. METHOD: This quantitative, prospective, longitudinal, and experimental study recruited 82 patients diagnosed with obesity and BED. The intervention was divided into eight individual weekly meetings, guided by ME sessions, nutritional educational dynamics, cooking workshops, food sensory analyses, and applications of questionnaires [Body Shape Questionnaire (BSQ); Binge Eating Scale (BES); Quality of Life Scale (WHOQOL-BREF)]. There was no dietary prescription for calories, carbohydrates, proteins, fats, and fiber. Patients were only encouraged to consume fewer ultra-processed foods and more natural and minimally processed foods. The meetings occurred from October to November 2023. STATISTICAL ANALYSIS: To carry out inferential statistics, the Shapiro-Wilk test was used to verify the normality of variable distribution. All variables were identified as non-normal distribution and were compared between the first and the eighth week using a two-tailed Wilcoxon test. Non-Gaussian data were represented by median ± interquartile range (IQR). Additionally, α < 0.05 and p < 0.05 were adopted. RESULTS: Significant reductions were found from the first to the eighth week for weight, BMI, waist circumference, episodes of binge eating, BSQ scale score, BES score, and total energy value (all p < 0.0001). In contrast, there was a significant increase in the WHOQOL-BREF score and daily water intake (p < 0.0001). CONCLUSIONS: ME improved anthropometric data, episodes of binge eating, body image dissatisfaction, eating habits, and quality of life in participants with obesity and BED in the short-term. However, an extension of the project will be necessary to analyze the impact of the intervention in the long-term.

Eating disorder symptom dimensions and protective factors: A structural network analysis study.

Eating Disorders (EDs) and related symptoms pose a substantial public health concern due to their widespread prevalence among both genders and associated negative outcomes, underscoring the need for effective preventive interventions. In this context, deepening our understanding of the interplay between ED symptoms and related protective factors appears crucial. Therefore, this study employed a structural network analysis approach considering both ED symptom dimensions (i.e., drive for thinness, bulimic symptoms, and body dissatisfaction) and related protective factors (i.e., body and functionality appreciation, intuitive eating, and self-esteem) to shed light on how these factors are interrelated. A community sample of 1391 individuals (34.4% men; Mage = 26.4 years) completed a socio-demographic schedule and self-report questionnaires. The network showed that the nodes with the highest positive expected influence were body and functionality appreciation, while those with the highest negative expected influence were eating for physical rather than emotional reasons and unconditional permission to eat (i.e., two components of intuitive eating). Crucially, the most relevant bridges between the conceptual communities "ED symptom dimensions" and "Protective factors" were the negative relations between (a) eating for physical rather than emotional reasons and bulimic symptoms, (b) unconditional permission to eat and drive for thinness, and (c) body appreciation and body dissatisfaction. Finally, age, gender, and body mass index did not moderate any edge in the network. The practical implications of these findings are discussed, especially in terms of preventive interventions for ED symptoms.

Affect trajectories surrounding binge eating episodes and heavy drinking episodes in adults with binge-spectrum eating disorders.

OBJECTIVE: The comorbidity of binge eating and heavy drinking (BE + HD) is concerning due to high prevalence and associated consequences. Affective pathways may maintain BE + HD, yet more micro-level research is needed. This study used ecological momentary assessment (EMA) to examine between-person and day-level relationships between positive and negative affect and binge eating or heavy drinking episodes in BE + HD. METHODS: Participants (N = 53) were adults with binge-spectrum eating disorders who completed between 7 and 14 days of EMA prior to a treatment for binge eating. RESULTS: Anxiety was highest on days with both binge eating and heavy drinking, while excitement and confidence were highest on days with only heavy drinking episodes for BE + HD. Global negative affect was relatively stable surrounding binge eating episodes. Guilt significantly increased prior to binge eating, and sadness significantly decreased following binge eating. Global positive affect significantly decreased prior to and stopped decreasing following heavy drinking episodes. DISCUSSION: Results support binge eating being negatively reinforced by specific aspects of negative affect, while heavy drinking may be positively reinforced by global positive affect for individuals with BE + HD. Clinicians should incorporate interventions that focus on specific negative affect dimensions and that promote alternative rewarding activities besides heavy drinking.

Prospective associations between cognitive flexibility and eating disorder symptoms in anorexia nervosa and bulimia nervosa.

This study investigated concurrent and prospective associations between measures of reversal learning and attentional set-shifting and eating disorder symptoms at baseline, 3 months, and 6 months among individuals with anorexia nervosa restricting subtype (AN-R, n = 26), AN binge eating/purging subtype (AN-BP, n = 22), bulimia nervosa (BN, n = 35), and healthy controls (n = 27), and explored whether these associations differed by diagnosis. At baseline, participants completed diagnostic interviews, height/weight measurements, and measures of set-shifting (the Intradimensional/Extradimensional shift task) and reversal learning (a probabilistic reversal learning task). At 3- and 6-month follow-up, participants with eating disorders completed assessments of weight and eating disorder symptoms. A one-way analysis of variance found no evidence that baseline reversal learning and attentional set-shifting differed across diagnostic groups. Multilevel modeling analyses indicated that perseverative errors (an index of reversal learning) predicted an increase in purging over time for individuals with AN-BP and BN. Set-shifting errors differentially predicted frequency of loss of control eating for individuals with AN-BP and BN; however, set-shifting was not related to loss of control eating when examined separately in AN-BP and BN. These findings suggest that disentangling facets of cognitive flexibility may help understand change in eating disorder symptoms.

Clarifying the pathway from anxiety sensitivity to binge eating: The mediating role of depressive symptoms in a 3-week, 3-wave longitudinal study of undergraduates.

Anxiety sensitivity (AS) - characterized by a persistent fear that arousal-related bodily sensations will lead to serious cognitive, physical, and/or social consequences - is associated with various psychopathologies, including depressive symptoms and binge eating. This 3-week, 3-wave longitudinal study examined the relation between AS (including its global AS factor and lower-order AS cognitive, physical, and social concern dimensions), depressive symptoms, and binge eating among 410 undergraduates from two universities. Using generalized estimating equation models, we found that global AS, AS social concerns, and depressive symptoms predicted binge eating during any given week. Mediation analyses showed that global AS (as a latent variable with its lower-order AS dimensions as indicators), AS cognitive concerns, and AS physical concerns at Wave 1 predicted subsequent increases in depressive symptoms at Wave 2, which, in turn, led to increases in binge eating at Wave 3. Findings contribute to a better understanding of the interplay between AS, depressive symptoms, and binge eating, highlighting the role of binge eating as a potential coping mechanism for individuals with high AS, particularly in managing depressive symptoms. This study underscores the importance of AS-targeted intervention and prevention efforts in addressing depressive symptoms and binge eating.

"I Haven't Told Anyone but You": Experiences and Biopsychosocial Support Needs of People With Type 2 Diabetes and Binge Eating.

Up to 25% of people with type 2 diabetes (T2D) may binge eat which is almost 10 times as many as in the general population. Binge eating is associated with depression, anxiety, and social isolation. Moreover, binge eating may increase the risk of obesity and high blood glucose levels, both of which can accelerate the onset of complications to diabetes and death in people with T2D. Still, little is known about the experiences, needs, and preferences of people with T2D and binge eating that can inform and develop current and future treatment efforts. The aim of the study was therefore to gain in-depth insights into the experiences and biopsychosocial support needs of women and men with T2D and binge eating. Twenty semi-structured individual interviews (65% with females) were conducted and analyzed according to the methodology of Interpretive Description. Four themes were identified: (a) T2D and binge eating: Feeling trapped in a vicious circle; (b) Unwanted outcasts: Responding to continuous criticism; (c) Biomedical relief: Blaming and adjusting the body; and, (d) Silent struggles: Wanting to cease the secrecy. Pertinent to all themes were the guilt, shame, and worries about developing complications that the participants experienced when binge eating despite having T2D. Although binge eating triggered emotional distress, binge eating was at the same time a way of coping with such distress. Implications for treatment and future research are discussed, including the need to systematically assess and address binge eating in routine T2D care.
