RESUMEN
Bulimia nervosa (BN) and other specific feeding or eating disorders with subthreshold BN symptoms (OSFED-BN) are characterized by recurrent binge eating episodes accompanied by compensatory behaviors, including excessive exercise. We aimed to examine the role of compensatory exercise on several clinical disorder-related variables and the treatment outcomes. The sample included 478 patients diagnosed with either BN or OSFED-BN admitted for a 16-week eating disorder-specific treatment program. A battery of questionnaires was administered to evaluate eating and general psychopathology, and personality traits. Other clinical disorder-related data, including levels of compensatory exercise, were assessed through a semi-structured clinical interview. Between-group comparisons of compensatory exercise levels were analyzed, as a predictive model of risk of poor treatment outcomes. Path analysis was conducted using structural equation models to estimate the direct and indirect effects between the main variables. Higher levels of self-reported compensatory exercise were associated with greater eating psychopathology, general psychopathology, and more dysfunctional personality traits and were a predictor of poor treatment outcomes. Additionally, these levels achieved a mediating role in several paths contributing to a higher likelihood of a poor outcome. Further research is required to determine how psychotherapeutic approaches can be optimized to adequately include adaptive exercise for these patients.

INTRODUCTION: Childhood maltreatment, particularly emotional abuse (EA), has been identified as a significant risk factor for the development of eating disorders (EDs). This study investigated the association between EA and ED symptoms while considering multiple potential mediators. METHODS: Participants included 151 individuals with Anorexia Nervosa (AN), 115 with Bulimia Nervosa (BN), and 108 healthy controls. The Childhood trauma questionnaire, the Toronto Alexithymia scale, the Behavioral inhibition System, and the Eating Disorder Inventory 2 scale were completed before treatment. A mediator path model was conducted in each group: EA was set as independent variable, eating symptoms as dependent variables and ineffectiveness, sensitivity to punishment, alexithymia, and impulsivity as mediators. RESULTS: In individuals with AN, impulsivity emerged as a significant mediator between EA and desire for thinness and bulimic behaviors. Conversely, in individuals with BN, sensitivity to punishment was found to mediate the association between EA and dissatisfaction with one's body. Ineffectiveness and difficulty identifying emotions were identified as transdiagnostic mediators in both clinical groups. No mediation effect was found in healthy individuals. DISCUSSION: The simultaneous assessment of multiple mediators in a unique model outlines the complex interplay between childhood EA and ED psychopathology. Improving ineffectiveness, emotion identification, sensitivity to punishment and impulsivity and exploring their relations with early emotional abuse may represent treatment targets in individuals with EDs and childhood trauma.

BACKGROUND: Existing evidence suggests that anterior insula plays a crucial role in cognitive control and emotional regulation and is implicated in the onset and maintenance of bulimia nervosa (BN). However, it remains unclear how structural and functional abnormalities in specific subregions of anterior insula contribute to BN. METHODS: In this study, we analyzed structural MRI and resting-state functional MRI data from 54 BN patients and 56 healthy controls (HCs). We conducted voxel-based morphometry, amplitude of low frequency fluctuation (conventional band: 0.01-0.08 Hz, slow-5: 0.01-0.027 Hz) and seed-based whole-brain functional connectivity (FC) analysis of the anterior insula subregions for both groups. Additionally, we investigated the correlation between neuroimaging findings and clinical characteristics in the BN group. RESULTS: Our findings revealed that BN patients exhibited reduced gray matter volume in the right dorsal anterior insula (dAI) and bilateral ventral anterior insula (vAI) and demonstrated decreased ALFF in slow-5 band of bilateral dAI. The BN group also showed increased FC between bilateral dAI and precuneus or right superior frontal gyri which significantly correlated with the severity of BN or its key symptom. In addition, the decreased FC between bilateral vAI and anterior cingulate and paracingulate gyri and/or median cingulate and paracingulate gyri were both significantly correlated with the severity and its restrained eating behavior. CONCLUSIONS: Our findings further indicate that the functional separation of anterior insula subregions may underlie the pathophysiology of BN. Notably, the vAI associated with emotional processing may serve as a promising neuroimaging biomarker which could inform therapeutic strategy.

Importance: Despite the existence of effective treatments, many individuals with bulimia nervosa (BN) do not receive evidence-based therapies. Integrating digital interventions into routine care might reach more patients and reduce the clinical burden of BN. Objective: To evaluate the effectiveness of a web-based cognitive behavioral self-help intervention for individuals with BN. Design, Setting, and Participants: A 2-group randomized clinical trial without follow-up was conducted between February 2, 2021, and July 9, 2022, in Germany. Participants aged between 18 and 65 years who met the diagnostic criteria for BN were enrolled online via self-referral. Data analyses were conducted from October 24, 2022, to December 23, 2023. Interventions: A web-based cognitive behavioral self-help intervention including 12 weekly modules was compared with a waiting-list control group only having access to routine care. Main Outcomes and Measures: The primary outcome was the change in the number of bulimic episodes between baseline and posttreatment. Secondary outcomes included changes in global eating disorder symptoms, clinical impairment, well-being, work capacity, comorbid symptoms, self-esteem, and emotion regulation complemented by weekly measures and ecological momentary assessment. Intention-to-treat analyses were performed. Results: Participants (N = 154; mean [SD] age, 29.6 [8.6] years; 149 [96.8%] female) receiving the web-based intervention demonstrated a significantly greater decrease in bulimic episodes compared with the control group (Cohen d = -0.48; 95% CI, -0.75 to -0.20; P < .001), representing a significant change in binge-eating episodes (Cohen d = -0.61; 95% CI, -0.89 to -0.33; P < .001), but not in compensatory behaviors (Cohen d = -0.25; 95% CI, -0.51 to 0.02; P = .21). The intervention was superior in improving global eating disorder symptoms (Cohen d = -0.61; 95% CI, -0.89 to -0.32; P < .001) and clinical impairment (Cohen d = -0.62; 95% CI, -0.92 to -0.33; P < .001). No significant effects were found for well-being (Cohen d = -0.08; 95% CI, -0.37 to 0.22; P > .99) and work capacity (Cohen d = -0.01; 95% CI, -0.68 to 0.66; P = .99). Exploratory analyses indicated significant changes in self-esteem and emotion regulation difficulties, but not in comorbid symptoms. Conclusions and Relevance: In this randomized clinical trial, a web-based cognitive behavioral self-help intervention effectively decreased eating disorder symptoms and illness-related burden in individuals with BN, underlining the potential of digital interventions to complement established treatments. Trial Registration: ClinicalTrials.gov Identifier: NCT04876196.

PURPOSE: Eating disorder (ED) awareness is low. We assessed if ED symptom recognition, perceived need for treatment, perceived distress, perceived acceptability, and perceived prevalence differed depending on the gender of the individual with the ED. METHODS: 276 community participants were randomly assigned to one of three gender conditions (female, male, and non-binary), read three vignettes describing three different individuals with ED symptoms [anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED)], and then answered a series of questions related to participants ED symptom recognition, perceived need for treatment, perceived distress associated with having ED symptoms, perceived acceptability (e.g., the extent to which it may not be too bad to have an ED), and perceived prevalence. Mixed ANOVAs and chi-square analyses were conducted to examine differences between groups. RESULTS: There were no significant main effects of gender condition across the outcome variables. There were main effects of ED type for problem recognition, perceived need for treatment, perceived level of distress, and perceived prevalence, with participants being more likely to recognize a problem in the AN and BN vignettes than the BED vignettes, refer for treatment and rate a higher perceived level of distress in then AN vignette than the BN and BED vignettes, and perceive a higher prevalence rate in the BN vignette than the AN vignette. There was a significant gender by condition interaction for perceived prevalence, with participants rating a higher prevalence of AN in women and non-binary individuals than men and a higher prevalence of BN in women than non-binary individuals and men. CONCLUSION: These results highlight the importance of education on EDs and awareness that EDs can occur in any individual, regardless of their gender identification. LEVEL OF EVIDENCE: Level I, experimental study with randomization.

BACKGROUND: Disordered eating behaviors are prevalent among youngsters and highly associated with dysfunction in neurocognitive systems. We aimed to identify the potential changes in individuals with bulimia symptoms (sub-BN) to generate insights to understand developmental pathophysiology of bulimia nervosa. METHODS: We investigated group differences in terms of degree centrality (DC) and gray matter volume (GMV) among 145 undergraduates with bulimia symptoms and 140 matched control undergraduates, with the secondary analysis of the whole brain connectivity in these regions of interest showing differences in static functional connectivity (FC). RESULTS: The sub-BN group exhibited abnormalities of the right dorsolateral prefrontal cortex and right orbitofrontal cortex in both GMV and DC, and displayed decreased FC between these regions and the precuneus. We also observed that sub-BN presented with reduced FC between the calcarine and superior temporal gyrus, middle temporal gyrus and inferior parietal gyrus. Additionally, brain-behavioral associations suggest a distinct relationship between these FCs and psychopathological symptoms in sub-BN group. CONCLUSIONS: Our study demonstrated that individuals with bulimia symptoms present with aberrant neural patterns that mainly involved in cognitive control and reward processing, as well as attentional and self-referential processing, which could provide important insights into the pathology of BN.

PURPOSE: Although insecure attachment and interpersonal problems have been acknowledged as risk and maintaining factors of eating disorders (EDs), the mediating role of interpersonal problems between attachment style and ED psychopathology has been poorly explored. The purpose of this study was to investigate the mediating role of interpersonal problems between insecure attachment and ED psychopathology. METHODS: One-hundred-nine women with anorexia nervosa and 157 women with bulimia nervosa filled in the Eating Disorder Inventory-2 (EDI-2) and the Experiences in Close Relationships (ECR) revised scale to assess ED core symptoms and attachment styles, respectively. Interpersonal difficulties were evaluated by the Inventory of Interpersonal Problems (IIP-32). A mediator's path model was conducted with anxious and avoidant attachment subscores as independent variables, ED core symptoms as dependent variables and interpersonal difficulties as mediators. The diagnosis was entered in the model as a confounding factor. RESULTS: The socially inhibited/avoidant interpersonal dimension was a mediator between avoidant attachment and the drive to thinness as well as between avoidant attachment and body dissatisfaction. An indirect connection was found between attachment-related anxiety and bulimic symptoms through the mediation of intrusive/needy score. CONCLUSIONS: Social avoidance and intrusiveness mediate the relationships between avoidant and anxious attachment styles and ED psychopathology. These interpersonal problems may represent specific targets for psychotherapeutic treatments in individuals with EDs and insecure attachment. LEVEL OF EVIDENCE: Level III: Evidence obtained from well-designed cohort or case-control analytic studies.

Because very few prospective studies have identified risk factors that predicted future onset of threshold/subthreshold anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD), we analyzed prospective data collected from a large cohort of adolescent girls followed over an 8-year period to advance knowledge about risk factor specificity. Adolescent girls recruited from middle schools in Texas (Nâ¯=â¯492; M ageâ¯=â¯13.02 [SDâ¯=â¯0.73], age rangeâ¯=â¯11-15) completed questionnaires assessing risk factors at baseline and diagnostic interviews assessing eating disorders annually over 8 years. Only low BMI predicted future AN onset. Pressure to be thin, thin-ideal internalization, body dissatisfaction, negative emotionality, low parent support, and modeling of eating pathology predicted future BN onset. Pressure to be thin, thin-ideal internalization, negative emotionality, low parent support, and modeling of eating pathology predicted future BED onset. Pressure to be thin, body dissatisfaction, dietary restraint, low parent support, modeling of eating pathology, and high BMI predicted future PD onset. Predictive effects were medium-to-large. Results support etiological theories of eating disorders that postulate the pursuit of the thin ideal, body dissatisfaction, negative affect, dietary restraint, and interpersonal issues increase risk for most eating disorders. The evidence that girls with low body weight are at risk for AN, whereas girls with high body weight are at risk for PD are novel. Although several risk factors predicted future onset of BN, BED, and PD, results suggest that risk factors for AN are qualitatively distinct and should be investigated further.

PURPOSE: The Eating Attitude Test-26 (EAT-26) is a screening tool for eating disorders (EDs) in clinical and non-clinical samples. The cut-off score was suggested to be varied according to target population. However, no studies have examined the appropriateness of the originally proposed score of 20 for screening DSM-5 eating disorders in Japan. This study aimed to identify an appropriate cut-off score to better differentiate clinical and non-clinical samples in Japan for EDs. METHODS: The participants consisted of 54 patients with anorexia nervosa restricting type, 58 patients with anorexia nervosa binge-eating/purging type, 37 patients with bulimia nervosa diagnosed according to DSM-5 criteria, and 190 healthy controls (HCs). Welch's t test was used to assess differences in age, body mass index (BMI), and total EAT-26 scores between HCs and patients with EDs. Receiver operating characteristic (ROC) analysis was conducted to identify the optimal cut-off score. RESULTS: The HCs had significantly higher BMI and lower total EAT-26 mean scores than patients with EDs. The area under the ROC curve was 0.925, indicating that EAT-26 had excellent performance in discriminating patients with EDs from HCs. An optimal cut-off score of 17 was identified, with sensitivity and specificity values of 0.866 and 0.868, respectively. CONCLUSIONS: The result supports the suggestions that optimal cut-off score should be different according to target populations. The newly identified cut-off score of 17 would enable the identification of patients with EDs who have been previously classified as non-clinical samples in the EAT-26 test. LEVEL OF EVIDENCE: III: evidence obtained from case-control analytic study.

BACKGROUND: Personality traits have been associated with eating disorders (EDs) and comorbidities. However, it is unclear which personality profiles are premorbid risk rather than diagnostic markers. METHODS: We explored associations between personality and ED-related mental health symptoms using canonical correlation analyses. We investigated personality risk profiles in a longitudinal sample, associating personality at age 14 with onset of mental health symptoms at ages 16 or 19. Diagnostic markers were identified in a sample of young adults with anorexia nervosa (AN, n = 58) or bulimia nervosa (BN, n = 63) and healthy controls (n = 47). RESULTS: Two significant premorbid risk profiles were identified, successively explaining 7.93 % and 5.60 % of shared variance (Rc2). The first combined neuroticism (canonical loading, rs = 0.68), openness (rs = 0.32), impulsivity (rs = 0.29), and conscientiousness (rs = 0.27), with future onset of anxiety symptoms (rs = 0.87) and dieting (rs = 0.58). The other, combined lower agreeableness (rs = -0.60) and lower anxiety sensitivity (rs = -0.47), with future deliberate self-harm (rs = 0.76) and purging (rs = 0.55). Personality profiles associated with "core psychopathology" in both AN (Rc2 = 80.56 %) and BN diagnoses (Rc2 = 64.38 %) comprised hopelessness (rs = 0.95, 0.87) and neuroticism (rs = 0.93, 0.94). For BN, this profile also included impulsivity (rs = 0.60). Additionally, extraversion (rs = 0.41) was associated with lower depressive risk in BN. LIMITATIONS: The samples were not ethnically diverse. The clinical cohort included only females. There was non-random attrition in the longitudinal sample. CONCLUSIONS: The results suggest neuroticism and impulsivity as risk and diagnostic markers for EDs, with neuroticism and hopelessness as shared diagnostic markers. They may inform the design of more personalised prevention and intervention strategies.

ABSTRACT: Eating disorders (EDs) represent a wide range of clinical symptoms related to food intake, body image, and weight issues, and include anorexia nervosa-restricting type (AN-R), anorexia nervosa-binge-purge type (AN-BP), and bulimia nervosa (BN). The aim was to investigate the characteristics of attachment, mentalization, emotion dysregulation, and empathy in a sample of 102 patients with EDs. A sample of 102 patients and therapists completed a series of measures for the assessment of ED pathology, mentalization, empathy, and emotion dysregulation. Pearson correlations and analysis of variance were used to test the characteristics of the variables among the groups. In relation to attachment and emotion dysregulation, no significant differences were found. In relation to mentalization, significant difference in good mentalization was found in AN-R subtype compared with the BN subtype. In relation to empathy, results showed significantly lower scores in BN subtype on affective empathy compared with the AN-BP subtype, and in AN-R subtype on cognitive empathy. Finally, we used Z -scores for each item ranked by value (higher to lower) to develop different clinical prototypes for each group. Our results point toward the clinical need to address the assessed variables, specifically mentalization, emotion dysregulation, and empathy, in the diagnosis and treatment of EDs.

BACKGROUND: Abdominal compartment syndrome (ACS) is typically attributed to critically unwell patients with trauma, burns, post surgery, and massive ascites. A rare but fatal cause of ACS is bulimia nervosa (BN), which is an eating disorder characterized by bingeing, followed by methods to avoid weight gain, including purging. CASE REPORT: We present a case of a 20-year-old woman who presented with abdominal pain and distension after consuming a large quantity of food the previous night and was unable to purge. She was initially managed conservatively and discharged home, but returned subsequently on the same day with clinical features of ACS secondary to acute gastric distension. Decompression resulted in life-threatening reperfusion injury with critical electrolyte abnormalities and fatal cardiac arrest in the operating theatre. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: A systematic review of the literature found only 11 case reports of ACS secondary to BN, of which only 6 patients survived due to early diagnosis and decompression. Inability to purge and lower limb ischemia appeared to be associated with increased mortality. As BN is a common emergency presentation, the case and systematic review highlights the need to consider ACS as a potentially life-threatening complication of binge eating, particularly when there is unsuccessful purging.

OBJECTIVE: Deterioration rate among patients with bulimia-spectrum eating disorders (BN-EDs) after receiving enhanced cognitive-behavioral therapy (CBT-E) remains high. Previous studies identified body image concerns, environmental triggers, lack of social support, lack of resources, comorbidity, and discontinued skill use as predictors of deterioration. However, no studies have qualitatively explored patients' perceptions of how these factors influenced their skill use and led to deterioration after receiving outpatient CBT. METHODS: This study aimed to qualitatively explore (1) what post-treatment factors patients believe contributed to deterioration, and (2) whether patients continued to practice the CBT skills they learned from treatment and identify motivators and barriers to post-treatment skill use. Twelve participants who had previously completed 16 sessions of CBT for their BN-EDs and experienced at least modest treatment responses participated in the qualitative interviews. RESULTS: Four themes were identified from the qualitative interviews. Post-treatment deterioration was primarily driven by decreased skill use due to a perceived sudden loss of accountability and continued body dissatisfaction after treatment ended. Discontinued practice of binge analysis led to decreased awareness of the relationship between poor skill use and ED behaviors. Difficulty accessing resources impeded participants from receiving external help to address challenges in skill practice, thus also contributing to deterioration. DISCUSSION: Findings suggested that outpatient treatment for BN-EDs patients should emphasize more on body image concern, and deterioration prevention for outpatient CBT-E should focus on building self-accountability to keep practicing skills after treatment ends. PUBLIC SIGNIFICANCE: This study was the first to qualitatively explore post-treatment factors influencing skill use and deterioration in patients with bulimia-spectrum eating disorders after they completed outpatient CBT. Findings indicated that decreased skill use was a primary driver of post-treatment deterioration, and that relapse prevention for outpatient CBT for BN-EDs should focus on enhancing patients' self-accountability to continue practicing therapeutic skills independently after treatment ended.

OBJECTIVE: The traditional measure of weight suppression (TWS; the difference between an individual's highest past weight at adult height and current weight), has been associated with many psychological, behavioral and biological variables in those with eating disorders. A new measure of weight suppression, called developmental weight suppression (DWS), corrects two major problems in the original measure. Initial research indicates that DWS represents a superior operationalization of the construct weight suppression was originally designed to measure (Lowe [1993, Psychol Bull, 114: 100]). This study is the first to examine the relation between both WS measures and weight history, body composition and a variety of metabolic hormones. METHODS: Data were collected in 91 women with bulimia nervosa (BN) or BN-spectrum disorders. RESULTS: Both weight suppression indices were related to multiple hormones. However, multiple regression analyses showed that the independent effects of DWS differed from the independent effects of TWS in that only DWS was negatively related to: (1) current z-BMI, (2) body fat percentage, and (3) insulin, leptin, T3 free, and TSH. This differential pattern also occurred when results were corrected for multiple comparisons. DISCUSSION: Findings provide stronger biological support for the construct validity of DWS than TWS and suggest that: (1) from the perspective of individuals with BN, high DWS embodies success at food restriction and weight loss, (2) elevated DWS may trap individuals with BN in a powerful biobehavioral bind, and (3) DWS is the preferred measure of weight suppression in future research on eating disorders. PUBLIC SIGNIFICANCE: Most individuals with bulimia nervosa lose substantial weight in the process of developing their disorder. Such weight suppression is related to many characteristics of those with the eating disorder bulimia nervosa. This study shows why a new measure of weight suppression, based on an individual's growth during development, is more biologically valid than the traditional measure of weight suppression.

BACKGROUND: Data concerning the suicide prevalence of eating disorder (ED) subtypes and predictive factors are lacking in youth. This study aimed to examine suicide attempts (SA), suicide ideation (SI) and self-harm (SH) upon diagnosis in adolescents with EDs. METHODS: The prevalence of SA, SI and SH in ED subtypes was evaluated by retrospectively assessing the Home, Education/Employment, Eating, Activities, Drugs, Sexuality, Suicidal ideation and Safety (HEEADSSS) instrument of adolescents diagnosed with an ED. Clinical predictors of SI in anorexia nervosa (AN) and atypical AN (AAN) were assessed. RESULTS: Among all participants (398), 41 (10.3%) reported SA, 126 (31.7%) SI and 60 (15.1%) SH. While SA did not differ statistically between ED subgroups (p = .123), they were two times more prevalent in the bulimia nervosa (BN) group (17.5%) than in the AN group (8.5%). In the BN group, SI was 2.3 times more prevalent than in the AN group (p = .001). The AN and ARFID groups exhibited substantially less SH (p = .036). Having a higher body mass index (BMI) was the only significant predictor of SI. CONCLUSIONS: This study demonstrates that adolescents with EDs are at an increased risk for suicidality, highlighting the need for close screening, particularly in those with BN, AN-BP and AN with a higher BMI.
Adolescents with eating disorders have higher rates of suicidality than the general population.Bulimia nervosa had the highest risk for a suicide attempt, suicide ideation and self-harm at diagnosis.A higher body mass index (BMI) percentage was associated with an increased risk of suicidality in the anorexia nervosa group.

BACKGROUND: The study aim to analyze the impact of interventions to help mitigate the influence of social networks on anorexia and bulimia nervosa. METHODOLOGY: A systematic review was conducted using PubMed, Scopus, PsycINFO and Web of Science. The inclusion criteria were: randomized clinical trials, published between 2013 and 2023 with a score = 5 points on the Van Tulder methodological quality scale. RESULTS: Eight studies were selected, most carried out in secondary education centers or universities; one was online. The study sample consisted of 5,084 participants mainly young women and adolescents with an average age between 12 and 32 years. As for the social networks, some studies described their impact at a general level, while others focused on Instagram, Facebook, Tik-Tok, Twitter, and Snapchat. A positive correlation was found between the exposure to unrealistic beauty ideals found in social networks with greater concern and dissatisfaction with body image. All studies used instruments to assess the effectiveness of the interventions. The interventions helped reduce the influence of the media and social networks, improve self-perception and self-esteem assessments, reduce anxiety levels and internalization of the thin beauty ideal, reduce dietary restrictions, and make use of social networks differently. CONCLUSIONS: Longer-lasting interventions can improve body satisfaction (one year) and depressive symptoms (six months), especially in women. Interventions should include attention to self-criticism, self-perception, self-esteem, body image, nutritional management, and media literacy skills.

OBJECTIVES: Negative urgency is associated with short-term maintenance of binge eating and purging in unselected samples. The current study used an eating disorder sample to test the hypothesis that negative urgency maintains bulimia nervosa (BN) and purging disorder (PD) at long-term follow-up. It was also hypothesized that baseline differences in negative urgency between BN and PD would remain at follow-up. METHODS: Secondary analyses were conducted on a sample of women who engaged in recurrent self-induced vomiting (n = 68; 52.9% BN; 47.1% PD). Women completed diagnostic interviews and questionnaires at baseline and at a mean (SD) of 5.95 (1.58) years follow-up (range = 2.51-9.62; retention rate = 75%). RESULTS: Negative urgency did not predict eating disorder diagnostic status, recovery status, or global eating pathology at follow-up (p's = .06-.83). There were no significant differences in negative urgency across women with BN and PD at follow-up (p = .16). However, post hoc analyses indicated that negative urgency was not stable across time (ICC = .102). Increases in negative urgency from baseline to follow-up were associated with greater global eating pathology at follow-up (p = .002). CONCLUSION: Results suggest negative urgency does not predict long-term eating disorder maintenance. Negative urgency may not be a stable personality trait but rather an indicator of overall poor emotion regulation. Future research should confirm that changes in negative urgency predict chronic eating pathology over long durations of follow-up in women who have increasing negative urgency across time.

Eating disorders (EDs) are common mental health conditions that carry exceedingly high morbidity and mortality rates. Evidence-based treatment options include a range of psychotherapies and some, mainly adjunctive, pharmacological interventions. However, around 20-30% of people fail to respond to the best available treatments and develop a persistent treatment-refractory illness. Novel treatments for these disorders are emerging, but their efficacy and clinical relevance need further investigation. In this review article, we first outline the evidence-base for the established treatments of the three 'classical' EDs [anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED)]. We then review research on some of the most promising emerging treatment modalities, discussing the questions and challenges that remain.

While individuals with Bulimia Nervosa (BN) and Binge Eating Disorder (BED) often present with a higher rate of Alcohol Use Disorder (AUD) than the general population, it is unclear whether this extends to AN. This cross-sectional study examined differences in alcohol-related behaviours, measured using the Alcohol Use Identification Test (AUDIT), between AN participants (n = 58), recovered AN (rec-AN) participants (n = 25), and healthy controls (n = 57). Statistical models controlled for age and ethnicity. The relationship between alcohol-related behaviours with ED psychopathology and with depression was also assessed. The findings indicated that acute AN participants were not at greater risk of AUD than healthy controls. However, rec-AN participants displayed greater total audit scores than those with acute AN, and more alcohol-related behaviours than healthy controls. Acute AN participants consumed significantly less alcohol than both the healthy control group and rec-AN group. No associations were found between ED psychopathology and alcohol-related behaviours in the AN group or rec-AN. This highlights alcohol as a potential coping mechanism following AN recovery. Clinicians should consider assessments for AUD and targeted interventions aimed at encouraging healthy coping mechanisms in this group. Future studies should look at alcohol use as a moderating factor for AN recovery.
