[THE OCTOBER MASSACRE AND IRON SWORDS WAR AS A TRIGGER FOR THE EMERGENCE OF EATING DISORDERS - A CASE SERIES].

INTRODUCTION: Eating disorders (EDs) are severe psychiatric disorders which entail substantial morbidity and mortality. Early detection and treatment are fundamental in determining prognosis. Exposure to traumatic events and acute stress are prominent risk factors for the emergence of EDs, while treatment delay may cause medical and psychiatric complications and lead to chronic illness. We describe a case series of two patients who recently presented to our center with anorexia nervosa, in which the latest events of the October massacre and the Iron Swords war were central in clinical deterioration and seeking treatment. We elaborate on the mechanisms in which the current emergency state may affect eating routines and lead to the development of EDs and emphasize the pivotal importance of efforts for early detection of new cases of EDs together with monitoring depression, anxiety, and post-traumatic symptoms. Given the heightened risk for the emergence of EDs at this time, early detection by health agents including parents, teachers, "resilience" centers and primary medicine teams is essential. We indicate that plans for early intervention that were prepared following the COVID-19 pandemic, may be implemented by family doctors and community-based dieticians to initiate therapy until treatment in a specialized ED center.

Vitamin D Status and Behavioral Impulsivity in Anorexia Nervosa: Insights from a Longitudinal Study.

Anorexia nervosa (AN) is a severe psychiatric disorder marked by extreme weight control behaviors and significant impacts on physical and psychosocial health. This study explores the relationship between vitamin D (Vit-D) levels and impulsivity in women with AN. Forty-six cisgender White women participants were assessed upon admission and before discharge from a specialized eating disorder treatment center, with an average duration of 2.5 ± 0.10 months. Methods included self-reported questionnaires and behavioral tasks to measure impulsivity, alongside serum Vit-D levels. Our results showed significant improvements in Vit-D levels and certain impulsivity measures, such as faster reaction times and fewer errors on the go/no-go task, correlating with higher Vit-D levels. However, no significant correlations were found between Vit-D levels and self-reported impulsivity. These findings suggest that adequate Vit-D levels may enhance cognitive functions related to impulse control in AN. Given this study's limitations, including its exclusive focus on women and small sample size, future research should involve larger, more diverse populations and randomized clinical trials to better understand the causal relationships and therapeutic potential of Vit-D in managing AN-related impulsivity.

Psychological Effects of Nasogastric Tube (NGT) in Patients with Anorexia Nervosa: A Systematic Review.

AIM: After the COVID-19 pandemic, the need for intensive nutritional care in patients affected with anorexia nervosa (AN) increased. The use of NGT was often used to overcome renutrition difficulties. This systematic review explores the evidence concerning the psychological effects of an enteral nasogastric tube (NGT) feeding on patients with AN. METHODS: A systematic review following PRISMA guidelines was conducted on electronic databases, including papers from January 2010 to December 2023. The keywords used combined anorexia nervosa, NGT, nasogastric tube, and tube feeding, with MeSH terms. No language limit was imposed. Reviews were excluded from the search. RESULTS: A total of 241 studies matched the keywords. Nevertheless, 236 studies were excluded from the review because they did not match the inclusion criteria. A total of six studies met the inclusion criteria. Of these, three studies were case series, one was a quantitative study of follow up and one was a qualitative exploratory study. The included studies described the hospitalization of patients with AN treated with a nasogastric tube; among these, only one study focused directly on the psychological correlates of nasogastric tube treatment using interviews with patients and medical staff. Included studies suggest that NGT feeding, even if faced in the first instance with prejudices and fears by patients, parents, and staff, is useful not only for weight increase in treatment-resistant patients with AN, but also alleviates their stress from feeding and, in general, it is psychologically well tolerated. Nevertheless, recent in-depth research on the issue is lacking and the existing has a low methodological quality; thus, many psychological effects of NGT application remain underexplored. CONCLUSIONS: Although the results suggest good psychological tolerance of the device, the limited data available recommend that more attention should be addressed by the researchers to the psychological consequences of the use of NGT in the treatment of AN since it is a nutrition disorder with prominent psychological roots. Further studies are needed.

No Evidence for Cross-Sectional or Longitudinal Associations between Cognitive Flexibility Performances and Nutritional Status in a Cohort of Inpatients with Anorexia Nervosa.

BACKGROUND: According to the Cognitive-Interpersonal model of anorexia nervosa (AN), the combined influence of cognitive and socio-emotional difficulties would constitute vulnerability and maintaining factors. Poor cognitive flexibility is one of the endophenotypic candidates (i.e., a trait marker) of the disorder, but few studies have examined its association with illness symptom variations, notably weight status. The study aimed to evaluate the relationships between cognitive flexibility performances and nutritional status indices (BMI; body composition) at different times of the disorder. METHODS: Cross-sectional and longitudinal associations between cognitive flexibility (TAP 2.1) and nutritional status indices, along with anxious and depressive (HAD) and eating disorder (EDE-Q) symptomatology were investigated using univariate and multivariate analyses in a cohort of AN inpatients evaluated at hospital admission (N = 167) and discharge (N = 94). RESULTS: We found no or negligible associations between nutritional status and HAD or EDE-Q scores or cognitive flexibility performances, either cross-sectionally or longitudinally. Cognitive performances did not significantly differ between the AN subtypes. CONCLUSIONS: In agreement with the Cognitive-Interpersonal model of AN, cognitive flexibility is independent of nutritional status, as well as the AN subtype. It is also independent of the levels of anxious, depressive, or ED symptomatology. A new therapeutic approach targeting cognitive flexibility and intolerance to change could benefit severely emaciated people with AN, regardless of disease subtype and level of dysphoria.

Impact of emotional abuse on eating disorder psychopathology: A multiple mediation analysis.

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.

The optimal cut-off score of the Eating Attitude Test-26 for screening eating disorders in Japan.

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.

Risk Factors That Predict Future Onset of Anorexia Nervosa, Bulimia Nervosa, Binge Eating Disorder, and Purging Disorder in Adolescent Girls.

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 (N = 492; M age = 13.02 [SD = 0.73], age range = 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.

The Relationship between Patient Self-Reported, Pre-Morbid Physical Activity and Clinical Outcomes of Inpatient Treatment in Youth with Anorexia Nervosa: A Pilot Study.

Links between premorbid physical activity (PA) and disease onset/course in patients with anorexia nervosa (AN) remain unclear. The aim was to assess self-reported PA as a predictor of change in percent median BMI (%mBMI) and length of hospital stay (LOS). Five PA domains were assessed via semi-structured interview in adolescents with AN at hospitalization: premorbid PA in school grades 1-6 (PA1-6); PA before AN onset (PA-pre) and after AN onset (PA-post); new, pathological motivation for PA (PA-new); and high intensity PA (PA-high). Eating disorder psychopathology was measured via the Eating Disorder Examination Questionnaire (EDE-Q), and current PA (steps/day) with accelerometry. PA1-6 was also assessed in healthy controls (HCs). Using stepwise backward regression models, predictors of %mBMI change and LOS were examined. Compared with 22 HCs (age = 14.7 ± 1.3 years, %mBMI = 102.4 ± 12.1), 25 patients with AN (age = 15.1 ± 1.7 years, %mBMI = 74.8 ± 6.0) reported significantly higher PA1-6 (median, AN = 115 [interquartile range IQR = 75;200] min vs. HC = 68 [IQR = 29;105] min; p = 0.017). PA-post was 244 ± 323% higher than PA-pre. PA1-6 was directly associated with PA-pre (p = 0.001) but not with PA-post (p = 0.179) or change in PA-pre to PA-post (p = 0.735). Lower %mBMI gain was predicted by lower baseline %mBMI (p = 0.001) and more PA-high (p = 0.004; r2 = 0.604). Longer LOS was predicted by higher PA-pre (p = 0.003, r2 = 0.368). Self-reported PA may identify a subgroup of youth with AN at risk of less weight gain and prolonged LOS during inpatient treatment for AN.

Nasogastric Tube Feeding in Anorexia Nervosa: A Propensity Score-Matched Analysis on Clinical Efficacy and Treatment Satisfaction.

The choice of a refeeding strategy is essential in the inpatient treatment of Anorexia Nervosa (AN). Oral nutrition is usually the first choice, but enteral nutrition through the use of a Nasogastric Tube (NGT) often becomes necessary in hospitalized patients. The literature provides mixed results on the efficacy of this method in weight gain, and there is a scarcity of studies researching its psychological correlates. This study aims to analyze the effectiveness of oral versus enteral refeeding strategies in inpatients with AN, focusing on Body Mass Index (BMI) increase and treatment satisfaction, alongside assessing personality traits. We analyzed data from 241 inpatients, comparing a group of treated vs. non-treated individuals, balancing confounding factors using propensity score matching, and applied regression analysis to matched groups. The findings indicate that enteral therapy significantly enhances BMI without impacting treatment satisfaction, accounting for the therapeutic alliance. Personality traits showed no significant differences between patients undergoing oral or enteral refeeding. The study highlights the clinical efficacy of enteral feeding in weight gain, supporting its use in severe AN cases when oral refeeding is inadequate without adversely affecting patient satisfaction or being influenced by personality traits.

A Comprehensive Study of Positive Body Image as a Predictor of Psychological Well-Being in Anorexia Nervosa.

Recent data suggest a close association between positive body image (PBI) and eating disorder recovery. Nevertheless, the specific mechanisms through which PBI may facilitate recovery from anorexia nervosa (AN) remain unknown. To advance understanding of these mechanisms, this study examined core indices of PBI within AN, exploring its association with emotion regulation and well-being outcomes. Data were collected from 159 female participants, 64 with AN diagnosis and 95 healthy controls (HCs), who completed measures of PBI (body appreciation, functionality appreciation, and body responsiveness), emotion regulation, and psychological well-being (depression, anxiety, stress, and psychological quality of life). The AN group reported lower levels of PBI and psychological well-being, along with greater difficulties in regulating emotions, relative to HCs. PBI variables significantly predicted emotion regulation and psychological well-being in AN, accounting for 36% to 72% of the variance, with body appreciation emerging as the strongest predictor. These findings lend credence to the view that PBI can serve as a catalyst for psychological health. We hypothesize that enhancing PBI can improve interoceptive awareness, which is crucial for emotion regulation and reducing maladaptive food-related coping. Emphasizing a mind-body connection in lifestyle could be a relevant element to consider for both treating and preventing AN.

Mediation role of interpersonal problems between insecure attachment and eating disorder psychopathology.

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.

Adolescents' perspectives on a novel digital treatment targeting eating disorders: a qualitative study.

BACKGROUND: Eating disorders in adolescence are associated with high psychological distress, impaired function and high comorbidity. Despite the severity, eating disorders remain highly underdiagnosed and untreated. Digital technology provides promising opportunities for treatment, however studies focusing on digital treatments for adolescents with eating disorders are lacking. The main aim of this study was to explore the perspectives of adolescents with lived experience of eating disorders on factors they deemed to be relevant in the development of a novel digital treatment. METHODS: A qualitative intervention development study using semi-structured individual interviews. Data collection, coding and analysis were conducted using the principles of reflexive thematic analysis. Participants were adolescents aged 16-19 years, with a self-reported diagnosis of anorexia nervosa, bulimia nervosa or binge eating disorder, currently in the final phase or completed psychological treatment for an eating disorder within the last five years. RESULTS: A total of 16 adolescents participated in the study, all females. Mean age was 17 ½ years (SD = 1.01). An in-depth understanding of the adolescents' perspectives was developed into three themes: Facilitating self-awareness and readiness to change; Strengthening interpersonal relationships and decreasing social isolation; Ensuring feeling seen and motivating regular use. CONCLUSIONS: This study provides a unique insight into the perspectives of adolescents with lived experience of eating disorders. The uptake and engagement can be optimized in a novel digital treatment for eating disorders by taking the adolescents perspectives into consideration.

Therapeutic Alliance in Family-Based Treatment of Anorexia Nervosa: In-Person Versus Telehealth.

OBJECTIVE: The therapeutic alliance is broadly linked with positive outcomes. However, nearly all research in this area involves in-person therapy, whereas teletherapy has grown increasing common since the COVID-19 pandemic. There is now a pressing need to establish whether the nature and importance of the therapeutic alliance is impacted by teletherapy. This study examined therapeutic alliance in families of youth with anorexia nervosa who were participating in a randomized controlled trial that transitioned from in-person to telehealth visits during the COVID-19 pandemic. METHOD: We analysed data from 53 adolescents and their parents (20 began in-person, 33 began with telehealth). Both parents, youth and therapist completed the Working Alliance Inventory-Short Revised after 4 weeks of treatment. RESULTS: We found no significant differences across telehealth and in-person treatment for paternal or therapist reported data. However, both adolescents and mothers reported higher bond and goal-related alliance for in-person sessions compared to telehealth. CONCLUSIONS: Findings regarding alliance across telehealth and in-person sessions were mixed, with some preference among mothers and youth for in-person treatment. Future studies should determine whether possible adaptations can improve working alliance during family-based treatment for anorexia nervosa via telehealth.

Enhancing emotional abilities in anorexia nervosa treatment: A rolling-group cognitive remediation and emotional skills training protocol.

INTRODUCTION: Anorexia nervosa (AN) is characterised by limited remission rates and emotional dimensions are often neglected. Cognitive remediation and emotional skills training (CREST) protocol aims to address cognitive and emotional factors. This study evaluates the feasibility and effectiveness of a modified rolling-group CREST protocol in an inpatient setting. METHODS: Quasi-experimental design evaluated CREST protocol in a rehabilitation programme. A total of 116 females diagnosed with AN were included, of whom 63 were included in the CREST protocol and 53 in the standard rehabilitation treatment. Various standardized measures were employed to assess psychopathology. Data collection occurred longitudinally, before and after CREST implementation. RESULTS: No significant differences emerged between groups regarding changes in specific eating psychopathology. CREST group exhibited significant improvements in emotion regulation (p = 0.002) and social skills (p = 0.014), besides a reduction in alexithymia (p < 0.001) and cognitive rigidity (p = 0.013). Empathic features remained stable. Participants reported positive perceptions of the CREST intervention. DISCUSSION: The study highlights the potential benefits of integrating emotional training within multidisciplinary intensive treatment for AN. Results emphasise the importance of treatment protocol with more affective and hot-cognition-related interventions, beyond weight-related psychopathology. Implementing a rolling-group CREST protocol in an inpatient setting showed promise in enhancing the emotional abilities of AN patients.

Intensive Cognitive Behavioral Therapy for Adolescents with Anorexia Nervosa Outcomes before, during and after the COVID-19 Crisis.

Studies comparing treatment outcomes in patients with eating disorders before and during the coronavirus (COVID-19) pandemic have yielded conflicting results. Furthermore, no study has yet evaluated treatment outcomes in adolescent patients with anorexia nervosa before, during and after the crisis. Hence, this study investigated the outcomes of an intensive Cognitive Behavioral Therapy-Enhanced (CBT-E) program on adolescents with anorexia nervosa consecutively treated before (n = 64), during (n = 37) and after (n = 31) the period of emergency spanning 8 March 2020 to 31 March 2022. Results show consistent and similar improvements in eating disorder psychopathology, general psychopathology and body mass index-for-age percentiles across all three periods, with approximately 60% of patients maintaining a full response at the 20-week follow-up, suggesting that treatment efficacy remained robust. Overall, the study underscores the effectiveness of intensive CBT-E as a viable treatment option for adolescents with anorexia nervosa, even during and after unprecedented challenges such as those posed by the COVID-19 pandemic.

Inpatient treatments for adults with anorexia nervosa: a systematic review of literature.

PURPOSE: Anorexia nervosa (AN) is a mental disorder for which hospitalization is frequently needed in case of severe medical and psychiatric consequences. We aim to describe the state-of-the-art inpatient treatment of AN in real-world reports. METHODS: A systematic review of the literature on the major medical databases, spanning from January 2011 to October 2023, was performed, using the keywords: "inpatient", "hospitalization" and "anorexia nervosa". Studies on pediatric populations and inpatients in residential facilities were excluded. RESULTS: Twenty-seven studies (3501 subjects) were included, and nine themes related to the primary challenges faced in hospitalization settings were selected. About 81.48% of the studies detailed the clinical team, 51.85% cited the use of a psychotherapeutic model, 25.93% addressed motivation, 100% specified the treatment setting, 66.67% detailed nutrition and refeeding, 22.22% cited pharmacological therapy, 40.74% described admission or discharge criteria and 14.81% follow-up, and 51.85% used tests for assessment of the AN or psychopathology. Despite the factors defined by international guidelines, the data were not homogeneous and not adequately defined on admission/discharge criteria, pharmacological therapy, and motivation, while more comprehensive details were available for treatment settings, refeeding protocols, and psychometric assessments. CONCLUSION: Though the heterogeneity among the included studies was considered, the existence of sparse criteria, objectives, and treatment modalities emerged, outlining a sometimes ambiguous report of hospitalization practices. Future studies must aim for a more comprehensive description of treatment approaches. This will enable uniform depictions of inpatient treatment, facilitating comparisons across different studies and establishing guidelines more grounded in scientific evidence. LEVEL OF EVIDENCE: Level I, systematic review.

Scoping review of end-of-life care for persons with anorexia nervosa.

BACKGROUND: End-of-life (EOL) care is the part of palliative care intended for persons nearing death. In anorexia nervosa (AN), providing EOL care instead of coercing life-sustaining measures is controversial. The existing literature has not been synthesized yet. To clearly delineate differing views and identify open questions as well as areas of possible consensus, we conducted the first-ever synthesis of the existing literature. METHODS: We searched EMBASE, PubMed, PsycInfo, and Web of Science for scientific publications on forgoing coerced life-sustaining measures and/or providing EOL care for persons with AN who refuse life-sustaining measures, typically artificial nutrition. Palliative care outside of the EOL context and medical assistance in dying were not reviewed. As very little quantitative studies were identified, we qualitatively analyzed conceptual questions, ethical reasoning, legal aspects, stakeholder attitudes, practical aspects, stakeholder needs, and outcome. RESULTS: We identified 117 eligible publications from 1984 to 2023, mainly case reports (n=26 different cases) and ethical analyses. Conceptualizations of key terms such as terminality, futility, and decision-making capacity (DMC) in AN varied widely and were often value-laden and circular. Ethical reasoning centered on weighing the preservation of life versus quality of life in the context of uncertainty about DMC and likelihood of clinical remission. Studies on stakeholder attitudes reflected this challenge. In some cases, courts ruled against coerced life-sustaining measures and/or in favor of EOL care for persons with AN. While eligibility criteria were contested, recommendations for deliberating about and providing EOL care were consistent. We identified only one study on stakeholder needs and none on outcome. Case reports described quality of life under EOL care as good and death as the most frequent outcome but engagement in voluntary treatment and (partial) clinical remission in some. CONCLUSIONS: The debate around EOL care in AN needs consented, coherent terminology whose value base is reduced to a minimum and made transparent. While more empirical research into decision-making in AN and predictors of outcome might help reduce uncertainty, fundamental normative questions need to be addressed, for example regarding the ethico-legal significance of treatment refusals, the weighing of quantity versus quality of life and the appropriateness of diagnosis-based ethico-legal exceptionalism such as hard paternalism. More research is needed on outcome of and stakeholder needs in EOL care for persons with AN.

Attachment, Mentalization, Emotion Dysregulation, and Empathy in Eating Disorders: Comparing Anorexic and Bulimic Patients.

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.

Distinct personality profiles associated with disease risk and diagnostic status in eating disorders.

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.

Body shape rather than facial emotion of others alters interpersonal distance in patients with anorexia nervosa.

OBJECTIVE: The study investigated interpersonal distance in patients with anorexia nervosa (AN), focussing on the role of other's facial expression and morphology, also assessing physiological and subjective responses. METHOD: Twenty-nine patients with AN and 30 controls (CTL) were exposed to virtual characters either with an angry, neutral, or happy facial expression or with an overweight, normal-weight, or underweight morphology presented either in the near or far space while we recorded electrodermal activity. Participants had to judge their preferred interpersonal distance with the characters and rated them in terms of valence and arousal. RESULTS: Unlike CTL, patients with AN exhibited heightened electrodermal activity for morphological stimuli only, when presented in the near space. They also preferred larger and smaller interpersonal distances with overweight and underweight characters respectively, although rating both negatively. Finally, and similar to CTL, they preferred larger interpersonal distance with angry than neutral or happy characters. DISCUSSION: Although patients with AN exhibited behavioural response to emotional stimuli similar to CTL, they lacked corresponding physiological response, indicating emotional blunting towards emotional social stimuli. Moreover, they showed distinct behavioural and physiological adjustments in response to body shape, confirming the specific emotional significance attached to body shape.
