Resistance to treatment and change in anorexia nervosa [corrected]: a clinical overview

Clinician bodies in eating disorder services: a commentary

This article discusses the important yet under-addressed issue of clinician bodies within eating disorder services. I would like to further the discussion on a particular correspondence in, where a professional who was perceived as dangerously thin was challenged and confronted by their colleagues in a work setting. This article will consider the issue from four perspectives, being the implications for the therapeutic relationship, how we approach biases and assumptions about weight and body size, ethical and legal issues, and how to manage lived experience. I argue for a more nuanced, considered approach towards professionals in the field before decisions are made to manage or confront them.

"I felt so powerful to have this love in me": A grounded theory analysis of the experiences of people living with and recovering from eating disorders while in diverse romantic relationships

Romantic partners have the potential to influence attitudes and behaviors related to body image and disordered eating. However, the role that romantic relationships can play in eating disorder (ED) recovery has not been comprehensively investigated. The present study aimed to explore the ways that people living with and recovering from EDs experience their romantic relationships, with the specific objective of developing a novel theoretical framework, grounded in the experiences of people in diverse romantic relationships, to guide future research on the topic. Semi-structured individual interviews were conducted with 66 people (45 cisgender women, 11 cisgender men, 9 nonbinary people, and 1 transgender man) living with and recovering from EDs while in romantic relationships. Our grounded theory analysis yielded a theoretical model of ED management in romantic relationships, revealing that Individual and Relationship Characteristics intersected with Relationship-Related Stressors and were navigated using Eating Disorder and Relationship Management Strategies. Combined with Partner Support and Tensions, these management strategies were related to Relationship and Mental Health Outcomes, which affected and were affected by Future Concerns. Future researchers should continue to build on, expand, and modify this model and further explore the role of romantic relationships in the experience of people living with EDs.

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.

Role of parental educational level as psychosocial factor in a sample of inpatients with anorexia nervosa and bulimia nervosa

Introduction

Evidence on parental educational level (PEL) as a risk factor for Eating Disorders (EDs) is mixed, and no study has assessed its role in relation to the compliance and outcomes of treatments in EDs. Further, no study differentiated from the educational level of mothers and fathers, nor considered the possible mediation of perfectionism in fostering EDs.

Methods

A clinical sample of 242 first-ever admitted inpatients with EDs provided information on PEL and completed the following questionnaires: the Eating Disorder Examination Questionnaire (EDE-Q) and the Frost Multidimensional Perfectionism Scale (F-MPS). Clinicians also provided information on the Hamilton Rating Scale for Anxiety (HAM-A) and the Hamilton Rating Scale for Depression (HAM-D) for each participant.

Results

Individuals with high PEL (whether mothers, fathers, or both parents) showed significantly higher scores on depressive symptoms and lower on parental criticism, were younger, had an earlier age of onset, had fewer years of illness, more were students and employed, and fewer had offspring. Individuals with fathers or both parents with high educational levels suffered more from Anorexia Nervosa rather than Bulimia Nervosa, had a longer length of stay during the current hospitalization, had less dietary restraint, and had higher personal standards. Individuals with mothers with high educational levels showed a lower rate of previous substance or alcohol addiction. Personal standards partially mediated the relationship between higher PEL and lower dietary restraint.

Discussion

PEL emerged to be a twofold psychosocial risk factor, being associated with higher depressive symptoms and a longer length of stay, but also with a shorter duration of illness and better scholar and working involvement. Higher PEL was related to higher personal standards but not to global perfectionism. Patterns of eating psychopathology emerged based on the high PEL of mothers or fathers.

Assessing motivation for treatment in eating disorders: psychometric validation of the Italian version of the Autonomous and Controlled Motivation for Treatment Questionnaire (ACMTQ-ITA)

PURPOSE

Treatment resistance is a significant challenge in addressing eating disorders (EDs). The Autonomous and Controlled Motivation for Treatment Questionnaire (ACMTQ) has been previously validated in ED populations to assess patients' motivation for treatment. This study aimed to validate the ACMTQ in the Italian language (ACMTQ-ITA) and evaluate its psychometric properties.

METHODS

We recruited a clinical sample of adults aged 18 or older, diagnosed with EDs, proficient in the Italian language, and providing written informed consent. Participants with psychiatric comorbidities such as schizophrenia, bipolar disorder, and substance use disorder were excluded from the study. Validity of the ACMTQ-ITA was assessed using reliability analysis with Cronbach's α and McDonald's ω estimates, and Confirmatory Factor Analysis (CFA).

RESULTS

Results from the reliability analysis confirmed the internal consistency of the Autonomous Motivation (AM) factor (α = 0.82, ω = 0.82), the Controlled Motivation (CM) factor (α = 0.76, ω = 0.77), and the ACMTQ-ITA overall score (α = 0.79). The CFA confirmed the two-factor solution (i.e., AM and CM) identified in the original validation of the ACMTQ (Comparative Fit Index = 0.92, Akaike Information Criterion = 3427.26, Bayesian Information Criterion = 3486.82; Root Mean Square Error of Approximation = 0.08, Standardized Root Mean Square Residual = 0.09).

CONCLUSION

The ACMTQ-ITA emerged as a valid and reliable tool for measuring motivation for treatment in individuals with EDs. Its implementation may facilitate the comprehension of treatment motivation, offering valuable clinical insights and implications for health management practices.

Clinical factors and early life experiences associated with therapeutic alliance development in treatment for depression or binge eating

OBJECTIVE

This study examines childhood and clinical factors theorized to impact therapeutic alliance development over the course of psychotherapy.

METHOD

Raters assessed the therapeutic alliance of 212 client-therapist dyads, participating in two randomized controlled trials of schema therapy and cognitive behavioural therapy for binge eating or major depression, at three time points. Linear mixed models were used to characterize therapeutic alliance development over time and assess the influence of childhood trauma, perceived parental bonding, diagnosis and therapy type on scores.

RESULTS

Participants differed in initial alliance ratings for all subscales but had similar growth trajectories in all but the patient hostility subscale. A diagnosis of bulimia nervosa or binge eating disorder predicted greater initial levels of client distress, client dependency and overall client contribution to a strong therapeutic alliance, compared with a diagnosis of depression. Therapy type, childhood trauma and perceived parental bonds did not predict alliance scores.

CONCLUSION

Findings highlight the potential influence of clinical and personal characteristics on alliance strength and development, with implications for maximizing treatment outcomes through anticipating and responding to these challenges.

The Nepean Belief Scale (NBS) as a tool to investigate the intensity of beliefs in anorexia nervosa: psychometric properties of the Italian version

BACKGROUND

People with anorexia nervosa (AN) show a peculiar impairment of insight regarding their condition, often manifesting a denial of extreme emaciation and sometimes hiding or underreporting socially undesirable abnormal eating patterns. Sometimes the intensity of the beliefs held by patients with AN reach a delusional intensity.

OBJECTIVES

In this study, the Italian version of the Nepean Belief Scale was applied to a sample of patients diagnosed with AN to investigate the intensity of their beliefs and convictions and its clinical correlates.

METHODS

The Nepean Belief Scale (NBS) was translated and adapted to Italian and applied to a sample of patients diagnosed with AN based on the Structured Clinical Interview for DSM-5 (SCID-5).

RESULTS

The Italian version of the 5-item NBS showed excellent reliability. Convergent validity was proved by negative association with levels of insight measured with the Schedule for the Assessment of Insight in Eating Disorders. Beliefs of delusional intensity were reported by 10% of participants. Those with a greater intensity of beliefs, either overvalued or delusional ideas, were more likely to report poorer general cognitive performances on the Montreal Cognitive Assessment. No association was observed between NBS score and age, body mass index, symptoms of eating disorders, body dissatisfaction, or levels of depression. Fear of weight gain and control seeking were the most often reported themes at the NBS.

CONCLUSIONS

The Italian version of the NBS is a reasonably reliable, valid, and usable tool for the multidimensional assessment of insight in AN. Level of evidence Level III, Evidence obtained from well-designed cohort or case-control analytic studies.

"You Don't Look Anorexic": Atypical anorexia patient experiences of weight stigma in medical care

Eating disorders (ED) and weight stigma pose significant healthcare challenges. Patients at higher weights, like some with atypical anorexia (AAN), may face increased challenges due to weight stigma. This study analyzed patients' lived experiences with weight stigma in healthcare. Thirty-eight adult patients with AAN completed in-depth, semi-structured interviews regarding healthcare experiences. Guided by narrative inquiry approaches, transcripts were thematically coded. Across the illness trajectory (ED development, pre-treatment, treatment, post-treatment), patients reported that weight stigma in healthcare contributed to initiation and persistence of ED behaviors. Themes included "providers pathologizing patient weight," which patients reported triggered ED behaviors and relapse, "provider minimization and denial" of patients' EDs, which contributed to delays in screening and care, and "overt forms of weight discrimination," leading to healthcare avoidance. Participants reported that weight stigma prolonged ED behaviors, delayed care, created suboptimal treatment environments, deterred help-seeking, and lowered healthcare utilization. This suggests that many providers (pediatricians, primary care providers, ED treatment specialists, other healthcare specialists) may inadvertently reinforce patients' EDs. Increasing training, screening for EDs across the weight spectrum, and targeting health behavior promotion rather than universal weight loss, could enhance quality of care and improve healthcare engagement for patients with EDs, particularly those at higher weights.

Cognitive Flexibility in Hospitalized Patients with Severe or Extreme Anorexia Nervosa: A Case-Control Study

OBJECTIVE

To investigate whether cognitive inflexibility could be identified using the Wisconsin Card Sorting Test (WCST) in patients with severe and extreme anorexia nervosa (AN) compared to healthy control participants (HCs).

METHOD

We used the WCST to assess 34 patients with AN (mean age: 25.9 years, mean body mass index (BMI): 13.2 kg/m²) 3-7 days after admission to a specialized nutrition unit and 34 HCs. The Beck Depression Inventory II and the Eating Disorder Inventory 3 were distributed.

RESULTS

The patients displayed more perseveration than HCs controlled for age and years of education, with moderate effect sizes (perseverative responses (%): adjusted difference = -7.74, 95% CI: -14.29-(-1.20), p-value: 0.021; perseverative errors (%): adjusted difference = -6.01, 95% CI: -11.06-(-0.96), p-value: 0.020). There were no significant relationships between perseveration and depression, eating disorder symptoms, illness duration, or BMI.

DISCUSSION

Patients with severe and extreme AN demonstrated lower cognitive flexibility compared to HCs. Performance was not related to psychopathology or BMI. Patients with severe and extreme anorexia nervosa may not differ from less severe patients in cognitive flexibility performance. As this study exclusively focused on patients suffering from severe and extreme AN, potential correlations might be masked by a floor effect.

Evaluation of multidimensional pediatric-psychosomatic inpatient therapy: a pilot study comparing two treatment modalities

Introduction

Multidimensional pediatric-psychosomatic inpatient treatment should be considered a highly relevant concept in the German healthcare system. This treatment concept has been successfully integrated to support youth with mental disorders and patients with chronic somatic conditions. Studies on treatment impact and empirical evidence of pediatric-psychosomatic inpatient therapies are rare, despite their clinical significance. Therefore, the study aims to provide initial indications of what constitutes to enhanced treatment effectiveness by comparing two different pediatric-psychosomatic inpatient treatment concepts. The clinics are comparable regarding the treated disorders, which include: dissociative, mood, and somatoform disorders, and psychological factors associated with chronic somatic conditions. Multidimensional treatment in both clinics include components of individual and family therapy, along with group-, art-, music-, creative-, and physio-therapy. Both clinics differed regarding their treatment philosophy in which; Clinic A practiced psychodynamic behavioral elements more strongly, while Clinic B rooted itself more strongly with psychoanalysis and family-dynamic practices.

Method

Each clinic recruited 25 patients for the study. They completed two questionnaires both at admission and discharge, which measured general behavioral and emotional problems (YSR); and, respectively, difficulties in emotion perception and processing (TAS-26). The effectiveness of the treatment was examined by conducting one-sample t-test and effect sizes for each clinic. To obtain information on differentiating treatment effects, mixed ANOVAs were calculated. For estimating its influence, the treatment duration was taken into account as a covariate calculating an ANCOVA.

Results

In both settings, treatment effects can be observed regarding internalizing problems. For alexithymia, no effects were seen in Clinic B, while in Clinic A, there was a significant reduction. When comparing both clinics, the ANOVAs showed significant interaction effects displaying advantages for Clinic A in the reduction of internalizing, total behavioral problems and alexithymia. Taking into account the treatment duration as a covariate, those effects level out. Significant differences between the clinics were no longer statistically detectable.

Discussion

The present study provides substantial preliminary indications on the effectiveness of multidimensional pediatric-psychosomatic inpatient therapy, which seems suitable for alleviating the general symptom burden and problems by identifying and processing emotions. Furthermore, the results indicate that an extended treatment duration may contribute to more pronounced effects.

Factor structure of the Young Positive Schema Questionnaire in an eating disorder sample

PURPOSE

The Young Positive Schema Questionnaire (YPSQ) measures early adaptive schemas (EAS) which could be used to develop positive psychology and schema-based interventions to benefit the treatment of eating disorders (EDs).

METHODS

The present study investigated the factor structure of the YPSQ in a sample of 826 participants (18-73 years; n = 753 women) with ED symptomatology (e.g., restricting, binging, and purging). The sample was randomly split into two groups for exploratory and confirmatory factor analyses. Full sample analysis using Pearson correlations was conducted to explore convergent validity of the new YSPQ factor structure with ED symptomatology, emotional regulation, and cognitive flexibility.

RESULTS

A nine-factor model was found, demonstrating good fit indices and internal consistency (α = 0.77-0.92). The YPSQ showed an inverse relationship to ED symptomatology and emotional suppression, and a positive relationship with cognitive flexibility and emotion reappraisal.

CONCLUSION

Further research is needed to explore the clinical benefits of the YPSQ to identify EAS deficits in individuals with EDs to improve treatment outcomes.

Evaluating thinking styles in adults with an eating disorder: Associations with life satisfaction, psychological symptoms, and treatment engagement

Cognitive weaknesses have been implicated as a vulnerability factor in the development and maintenance of eating disorders. Despite this, cognitive styles are not routinely assessed in adult outpatient eating disorder programs and little is known about how they may impact patients' functional outcomes, psychological symptoms, or treatment engagement. The aim of this study was to evaluate thinking styles (i.e., cognitive rigidity and attention to detail) among adults attending specialized outpatient treatment for an eating disorder and assess whether such styles were associated with participants' satisfaction with life, psychological symptoms, and engagement in the outpatient group therapy program. Demographic and physical health information was collected from 95 adults who were eligible for an outpatient program. Participants completed the Detail and Flexibility Questionnaire, Satisfaction with Life Scale, Beck Depression Inventory second edition, and Beck Anxiety Inventory. Elevated scores for cognitive rigidity and attention to detail were transdiagnostic rather than specific to eating disorder diagnoses. Cognitive rigidity and attention to detail were associated with lower satisfaction with life, and increased anxiety and depression. Cognitive styles of cognitive rigidity and attention to detail were not associated with engagement in treatment or treatment completion. Cognitive patterns may be important for clinicians to evaluate as part of routine outpatient care given that they occur transdiagnostically and are linked with psychological symptoms and functional outcomes for adults struggling with an eating disorder.

Experiencing eight psychotherapy approaches devoted to eating disorders in a single-day workshop increases insight and motivation to engage in care: a pilot study

PURPOSE

For patients with eating disorders (EDs), early engagement in care is usually considered a positive prognostic factor. The aim of the study was to investigate how a single-day intervention devoted to early, brief, experiential exposure to a variety of psychotherapy approaches might support commitment to change and the decision to engage in care in patients with EDs.

METHODS

One hundred and sixty-nine adult outpatients newly diagnosed with an ED took part in a single-day workshop for groups of up to ten patients, where they experienced eight psychotherapeutic approaches. Motivation to change care and level of insight were assessed at baseline and 10 days after the intervention.

RESULTS

Motivation and commitment to take active steps toward change (expressed by the "Committed Action" composite score) significantly improved after the intervention (p < 0.001), and a significant number of patients specifically moved from "contemplation" to "action" stage (p < 0.001). The improvement of motivation to change was significantly associated with an increase in insight capacity (p < 0.001), and this increase was observed for almost all related dimensions such as recognition of illness or awareness of need for psychological treatment.

CONCLUSION

A single-day session devoted to experiencing a range of group psychotherapies increased patients' insight and motivation to actively engage in care. To confirm potential longer-term benefits of this intervention, further studies are needed to explore the contribution of each approach and process specifically involved in patients' increased motivation for care, as well as the clinical characteristics of patients associated with better outcomes.

Predictors of outcome following a body image treatment based on acceptance and commitment therapy for patients with an eating disorder

BACKGROUND

It is important to target body image in individuals with an eating disorder (ED). Acceptance and commitment therapy (ACT) has been trialed in a few studies for individuals with an ED. Although ACT outcomes in ED patients hold promise, studies of predictors are scarce. The aim of the present study was to explore differences in ED symptom outcome at two-year follow-up in subgroups of participants attending either treatment as usual (TAU), or a group intervention based on ACT targeting body image. Additionally, we aimed to compare subjective recovery experiences between groups.

METHODS

The study took place at a specialized ED outpatient clinic, and included patients diagnosed with an ED that had received prior treatment and achieved a somewhat regular eating pattern. Study participants were randomly assigned to continue TAU or to participate in a group intervention based on ACT for body image issues. Only participants that completed the assigned intervention and had completed follow up assessment by two-years were included. The total sample consisted of 77 women.

RESULTS

In general, ACT participants showed more favorable outcomes compared to TAU, and results were more pronounced in younger participants with shorter prior treatment duration and lower baseline depression ratings. Participants with restrictive ED psychopathology had three times higher ED symptom score change if participating in ACT in comparison to TAU.

CONCLUSIONS

An ACT group intervention targeting body image after initial ED treatment may further enhance treatment effects. There is a need for further investigation of patient characteristics that might predict response to body image treatment, particularly regarding ED subtypes and depression ratings.

The role of the lateral septum in neuropsychiatric disease

The lateral septum (LS) is a structure in the midline of the brain that is interconnected with areas associated with stress and feeding. This review highlights the role of the LS in anxiety, depression, and eating disorders and their comorbidity. There is a prevailing view that the LS is anxiolytic. This review finds that the LS is both anxiolytic and anxiogenic. Furthermore, the LS can promote and inhibit feeding. Given these shared roles, the LS represents a common site for the comorbidity of neuropsychiatric disorders, and therefore a potential pharmacological target. This is crucial since currently available treatments are not always effective. Corticotrophin-releasing factor 2 antagonists are potential drugs for the treatment of anxiety and anorexia and require further research. Furthermore, other drugs currently in trials for binge eating, such as alpha-adrenergic agonists, may in fact promote food intake. It is hoped that the advancements in chemo- and optogenetic techniques will allow future studies to profile the specific neural connections of the LS and their function. This information could facilitate our understanding of the underlying mechanisms, and therefore pharmacological targets, of these psychiatric conditions.

Impact of the coronavirus pandemic on anorexia nervosa and atypical anorexia nervosa presentations to an Australian tertiary paediatric hospital

AIM

The coronavirus (COVID-19) pandemic has led to increased concerns about adolescent mental health. This study aimed to determine the effect of the pandemic on adolescent eating disorders (EDs) by measuring changes in the number and severity of presentations to an Australian paediatric ED service that utilises a standardised approach to triage and assessment.

METHODS

A 4-year retrospective chart review (2017-2020) of all patients (n = 457) presenting to the Royal Children's Hospital Eating Disorder Service, Melbourne, was undertaken. The incidence of each diagnosis and measures of condition severity were extracted from the database and patient medical records. Clinical comments relating to the impact of COVID-19, on both ED behaviours and treatment, were also noted.

RESULTS

Annual presentations increased from a mean of 98.7 per annum from 2017 to 2019 to 161 in 2020 (63% increase). COVID-19 restrictions were reported to be a trigger for ED behaviours in 40.4% of adolescents diagnosed with anorexia nervosa in 2020. There was no significant difference in severity across years despite increased cases.

CONCLUSIONS

The dramatic increase in presentations has implications for primary health and paediatric care as well as specialist ED services. Increased support is needed for EDs during this time.

Investigating Service Users' Perspectives of Eating Disorder Services: A Meta-Synthesis

Objective

Despite a number of qualitative studies published from the perspective of eating disorder (ED) service users, there has been no attempt to exclusively synthesize their views to gain a fuller understanding of their ED service experiences. It is important to understand this perspective, since previous research highlights the difficulties ED healthcare professionals report when working with this client group.

Method

A systematic search of the literature was conducted to identify qualitative studies focusing on experiences of ED services from the perspective of service users. Twenty‐two studies met the inclusion criteria and underwent a quality appraisal check using the Critical Appraisal Skills Programme (CASP) tool for qualitative research. These were then synthesized using a meta‐synthesis approach.

Results

Four overarching themes were generated: “Treatment: Focus on physical vs. psychological symptoms”; “Service Environment: The role of control within services”; “Staff: Experiences with staff and the value of rapport”; and “Peer Influence: Camaraderie vs. comparison.” Service users expressed a desire for more psychological input to tackle underlying difficulties relating to their ED. A complex relationship with feelings of control was described, with some feeling over‐controlled by service providers, while others retrospectively recognized the need for control to be taken away. Staff values, knowledge and trust played a significant role in treatment and recovery. Peers with an ED were described to be a valuable source of understanding and empathy, but some found peer influence to perpetuate comparison and competitiveness.

Discussion

The results portray some of the conflicts and complexities that service users encounter in ED services. A running thread throughout is the perceived importance of adopting an individualized approach within these services.

How Is the History of Early Traumatic Exposure Associated With the Psychopathological Outcomes of COVID-19 Related Lockdown and Subsequent Re-opening in People With Eating Disorders?

The negative impact of COVID-19 pandemic on people with Eating Disorders (EDs) has been documented. The aim of this study was to evaluate whether a history of traumatic experiences during childhood or adolescence was associated with a higher degree of psychopathological worsening during COVID-19 related lockdown and in the following re-opening period in this group of people. People with EDs undergoing a specialist ED treatment in different Italian services before the spreading of COVID-19 pandemic (n = 312) filled in an online survey to retrospectively evaluate ED specific and general psychopathology changes after COVID-19 quarantine. Based on the presence of self-reported traumatic experiences, the participants were split into three groups: patients with EDs and no traumatic experiences, patients with EDs and childhood traumatic experiences, patients with EDs and adolescent traumatic experiences. Both people with or without early traumatic experiences reported retrospectively a worsening of general and ED-specific psychopathology during the COVID 19-induced lockdown and in the following re-opening period. Compared to ED participants without early traumatic experiences, those with a self-reported history of early traumatic experiences reported heightened anxious and post-traumatic stress symptoms, ineffectiveness, body dissatisfaction, and purging behaviors. These differences were seen before COVID-19 related restrictions as well as during the lockdown period and after the easing of COVID-19 related restrictions. In line with the "maltreated ecophenotype" theory, these results may suggest a clinical vulnerability of maltreated people with EDs leading to a greater severity in both general and ED-specific symptomatology experienced during the exposure to the COVID-19 pandemic.

Compliance and resistance to treatment in an Italian residential Centre for eating disorders

The dominant biomedical model perceives eating disorders as mental disorders and its 'sufferers' as people who need to be healed. It follows that people diagnosed with an eating disorder are pressured to accept medical and psychological care due to the moral obligations that are associated with the sick role, as delineated by Parsons. This, however, does not necessarily imply that they are willing to heal. By analysing compliance and resistance to treatment in an Italian residential Centre for eating disorders, this paper suggests that patients may accept medical care in order to achieve objectives other than those for which power is exerted over them. By complying with treatment, patients may in fact attempt to (re)become anorexic or escape from their everyday environment and problems. It is therefore argued that biomedical power can be subverted from within through the adoption of what De Certeau defines as tactics.

Disordered eating through the lens of positive psychology: The role of embodiment, self-esteem and identity coherence

Applying a positive psychology perspective, this study aimed to identify potential intra-individual factors that might protect against the development of disordered eating in a community sample of young women and men (N = 510; 56 % women; M_age = 24.3). Based on existing literature, the study included the general resilience factors of self-esteem and identity coherence as well as two dimensions of positive embodiment (positive body connection and comfort, and agency and functionality). All factors were negatively correlated with disordered eating among women and men. Hierarchical regression analyses indicated that positive embodiment, specifically positive body connection, was a significant predictor of lower degrees of disordered eating symptoms in both women and men, followed by self-esteem. The overall prediction model accounted for 42.6 % in the variation of disordered eating symptoms for women and 23.9 % for men. Prevention and treatment interventions promoting health factors that protect against the development of eating disorders are much needed. The present study informs such efforts by emphasizing the promotion of positive embodiment.

Symptoms of disturbed eating behavior risk: Gender and study factors in a cross-sectional study of two Norwegian medical schools

BACKGROUND

Studies about medical student's stress associated with disturbed eating behavior are scarce.

OBJECTIVES

To study the explanatory role of curricular factors and distress in disturbed eating behavior among medical students and whether this varies according to gender, study stage, curriculum model, study stress and mental distress.

METHODS

The cross-sectional sample surveyed consisted of Norwegian medical students at two faculties with different curricular models (traditional and integrated). The total response rate was 64% (1044/1635). We tested differences in disturbed eating behavior symptoms (EDS) and their correlates using stepwise linear regression analysis.

RESULTS

In total, 18.3% were cases of disturbed eating behavior symptoms, including 23.5% of female and 5.6% of male participants. Disturbed eating behavior symptoms were independently associated with the medical school stress factors "medical school is cold and threatening" (β = 0.07, p = .041), "worries about work and competence" (β =0.15, p < .001) and "worries about finances and accommodation" (β = 0.07, p = .018), in addition to female gender (β = 0.30, p < .001), mental distress (β = 0.17, p < .001), and body mass index (β = 0.28, p < .001). The variables explained 28.9% of the variance in disturbed eating behavior symptoms, and medical school stress contributed 9%. "Worries about work and competence" was more important among the female students.

CONCLUSIONS

Nearly one in five female medical students in the current sample reported symptoms of disturbed eating behavior. The symptoms were associated with medical school stress factors, mental distress, and body mass index.

Study Protocol for "Psilocybin as a Treatment for Anorexia Nervosa: A Pilot Study"

Background: Anorexia nervosa (AN) is a serious and life-threatening psychiatric condition. With a paucity of approved treatments, there is a desperate need for novel treatment avenues to be explored. Here, we present (1) an overview of the ways through which Public Patient Involvement (PPI) has informed a trial of psilocybin-assisted therapy for AN and (2) a protocol for a pilot study of psilocybin-assisted therapy in AN currently underway at Imperial College London. The study aims to assess the feasibility, brain mechanisms and preliminary outcomes of treating anorexia nervosa with psilocybin. Methods: (1) PPI: Across two online focus groups, eleven individuals with lived experience of AN were presented with an overview of the protocol. Their feedback not only identified solutions to possible barriers for future participants, but also helped the research team to better understand the concept of "recovery" from the perspective of those with lived experience. (2) Protocol: Twenty female participants [21-65 years old, body mass index (BMI) 15 kg/m2 or above] will receive three oral doses of psilocybin (up to 25 mg) over a 6-week period delivered in a therapeutic environment and enveloped by psychological preparation and integration. We will work with participant support networks (care teams and an identified support person) throughout and there will be an extended remote follow-up period of 12 months. Our two-fold primary outcomes are (1) psychopathology (Eating Disorder Examination) across the 6-month follow-up and (2) readiness and motivation to engage in recovery (Readiness and Motivation Questionnaire) across the 6-week trial period. Neurophysiological outcome measures will be: (1) functional magnetic resonance imaging (fMRI) brain changes from baseline to 6-week endpoint and (2) post-acute changes in electroencephalography (EEG) activity, including an electrophysiological marker of neuronal plasticity. Discussion: The results of this pilot study will not only shed light on the acceptability, brain mechanisms, and impression of the potential efficacy of psilocybin as an adjunct treatment for AN but will be essential in shaping a subsequent Randomised Control Trial (RCT) that would test this treatment against a suitable control condition. Clinical Trial Registration: identifier: NCT04505189.

Predictors of Stepping Up to Higher Level of Care Among Eating Disorder Patients in a Partial Hospitalization Program

Partial hospitalization programming (PHP) is a treatment option available for individuals with eating disorders (ED) who have made insufficient progress in outpatient settings or are behaviorally or medically unstable. Research demonstrates that this level of care yields efficacy for the majority of patients. However, not all patients achieve recovery in PHP and later admit to a higher level of care (HLOC) including residential treatment or inpatient hospitalization. Although PHP is an increasingly common treatment choice for ED, research concerning outcome predictors in outpatient, stepped levels of care remains limited. Thus, the current study sought to identify the predictors of patients first admitted to PHP that later enter residential or inpatient treatment. Participants were 788 patients (after exclusions) enrolled in adolescent or adult partial hospitalization programs in a specialized ED clinic. When compared to patients who maintained treatment in PHP, a significantly greater proportion of patients who discharged to a HLOC had previously received ED residential treatment. Moreover, patients who discharged to a HLOC were diagnosed with a comorbid anxiety disorder and reported greater anxious and depressive symptomatology. A logistic regression model predicting discharge from PHP to a HLOC was significant, and lower body mass index (BMI) was a significant predictor of necessitating a HLOC. Supplemental programming in partial hospitalization settings might benefit individuals with previous ED residential treatment experience, higher levels of anxiety and depression, and lower BMIs. Specialized intervention for these cases is both practically and economically advantageous, as it might reduce the risk of rehospitalization and at-risk patients needing to step up to a HLOC.

Prediction of eating disorder treatment response trajectories via machine learning does not improve performance versus a simpler regression approach

OBJECTIVE

Patterns of response to eating disorder (ED) treatment are heterogeneous. Advance knowledge of a patient's expected course may inform precision medicine for ED treatment. This study explored the feasibility of applying machine learning to generate personalized predictions of symptom trajectories among patients receiving treatment for EDs, and compared model performance to a simpler logistic regression prediction model.

METHOD

Participants were adolescent girls and adult women (N = 333) presenting for residential ED treatment. Self-report progress assessments were completed at admission, discharge, and weekly throughout treatment. Latent growth mixture modeling previously identified three latent treatment response trajectories (Rapid Response, Gradual Response, and Low-Symptom Static Response) and assigned a trajectory type to each patient. Machine learning models (support vector, k-nearest neighbors) and logistic regression were applied to these data to predict a patient's response trajectory using data from the first 2 weeks of treatment.

RESULTS

The best-performing machine learning model (evaluated via area under the receiver operating characteristics curve [AUC]) was the radial-kernel support vector machine (AUCRADIAL = 0.94). However, the more computationally-intensive machine learning models did not improve predictive power beyond that achieved by logistic regression (AUCLOGIT = 0.93). Logistic regression significantly improved upon chance prediction (MAUC[NULL] = 0.50, SD = .01; p <.001).

DISCUSSION

Prediction of ED treatment response trajectories is feasible and achieves excellent performance, however, machine learning added little benefit. We discuss the need to explore how advance knowledge of expected trajectories may be used to plan treatment and deliver individualized interventions to maximize treatment effects.

The costs of over-control in anorexia nervosa: evidence from fMRI and ecological momentary assessment

A growing body of evidence suggests that a high level of self-control may, despite its positive effects, influence cognitive processing in an unfavorable manner. However, the affective costs of self-control have only rarely been investigated. Anorexia nervosa (AN) is an eating disorder that is often characterized by excessive self-control. Here, we used fMRI to explore whether over-control in AN may have negative affective consequences. 36 predominantly adolescent female AN patients and 36 age-matched healthy controls (HC) viewed negative and neutral pictures during two separate fMRI sessions before and after 10 min of rest. We tested whether abnormally elevated neural activity during the initial presentation in a brain region broadly implicated in top-down control, the dorsolateral prefrontal cortex (dlPFC), could predict subsequent activation in limbic areas relevant to bottom-up affective processing. Using ecological momentary assessment (EMA), we also tested for associations between the aforementioned neuroimaging markers and negative affective states in the two weeks following the experiment. fMRI data revealed that higher initial activation of the dlPFC in AN predicted increased amygdala reactivity during the second fMRI session, which in turn was related to increased self-reported tension during two weeks following the scan. These data suggest that over-control in AN patients may come at a cost including negative affective states on a short (minutes) as well as a longer time scale (days). This mechanism may significantly contribute to the persistence of AN.

Clinical and Cognitive Functioning Changes After Partial Hospitalization in Patients With Anorexia Nervosa

Introduction: Anorexia nervosa is usually associated with emotional and cognitive difficulties. Little knowledge is available about the changes in cognitive functioning in patients undergoing treatments. The aim of the present study was to longitudinally assess the impact of partial hospitalization on clinical and cognitive functioning in anorexia nervosa. Materials and Methods: 56 women with anorexia nervosa according to DSM-5 criteria and 58 healthy women were enrolled in the study. At baseline, all participants underwent clinical, diagnostic and neuropsychological assessment (T0). Patients were also assessed at the end of the treatment program (T1; n = 56). Results: BMI improved significantly throughout treatment. At baseline, patients showed significantly poorer executive abilities and less specific autobiographical memory. After the day-hospital program, decision-making abilities improved significantly. Response to treatment was predicted by BMI at admission and duration of illness, but neuropsychological performance did not contribute to the prediction model. Discussion: Cognitive difficulties, mostly regarding executive functions, resulted differently affected by clinical improvement. In particular, while cognitive monitoring and cognitive inhibition appear to be mostly stable trait-like characteristics, decision-making is both more state-dependent and sensitive to clinical status. None of the cognitive variables added information about the response to day hospital treatment; patients with short duration of illness and a rapidly decreasing BMI would benefit more from intensive interventions than less "acute" patients. These observations, if confirmed by future studies, have important clinical implications in order to understand the impact of malnutrition on cognitive functioning and to provide individualized effective treatment for patients with anorexia nervosa.

Critical incidents in anorexia nervosa: perspectives of those with a lived experience

BACKGROUND

Although social-emotional difficulties are believed play a key role in anorexia nervosa (AN), there is uncertainty regarding what these difficulties might look like. Previous research has largely focused on a "disease model" of social-emotional processing in AN with little attention paid to positive emotions and experiences. Therefore, the aim of the present study was to obtain a fuller picture of critical life events as identified by those with lived AN experience.

METHODS

Thirty-four participants aged 16-48 with current or past AN completed an online survey describing self-defined positive and difficult critical events. Thematic analysis was used to assess patterns in participants narrative responses.

RESULTS

Two major themes were identified in the descriptions of positive critical events: Moments of celebration and Unexpected positive outcomes. These major themes revealed increased external focus and some corrective experiences that challenged the participants pre-existing expectations leading to new positive outcomes. Difficult events clustered into life events that were identified as Eating disorder (ED) related and Non-ED related and included the dimensions of relational conflict and feeling unsupported.

DISCUSSION

The findings suggest that although negative emotionality was identified in the accounts of those with lived experience of AN capacity for "big-picture" thinking with and explicit focus on others was also identified. Moreover, an openness to corrective experiences that worked to challenge negative expectations was evident for some participants. Together these findings have scope as targets for further clinical research and treatment interventions.

The song of Anorexia Nervosa: a specific evoked potential response to musical stimuli in affected participants

PURPOSE

Research applying electroencephalography (EEG) to Anorexia Nervosa (AN) is still limited, even though in other psychiatric disorders EEG has permitted to find out the hallmarks of the disorder. The aim of the study was to explore whether EEG basal activity and reactivity to musical stimulation differ in participants with AN as compared to healthy subjects (HS).

METHODS

Twenty female participants (respectively 10 with AN and 10 healthy controls) were administered a battery of psychometric tests and underwent EEG under three different conditions: (1) at baseline; (2) after a generic music stimulation; and (3) after a favorite musical stimulation.

RESULTS

In participants with AN, basal EEG showed the higher absolute amplitude of cortical slow waves (theta) in the parieto-occipital and temporal derivations, with a deficit in the beta band. In AN, there was a higher N100 latency and a reduced P300 latency compared to HS. While the N100 and P300 latencies were sensitive to the musical stimulus in HS, there was no difference after music stimulation in AN.

CONCLUSION

These data suggest that AN is accompanied by a state of brain hyperarousal with abnormal reactivity to environmental stimuli, similar to the state of HS after musical stimulation. If confirmed, this finding may have treatment implications.

The impact of the COVID-19 pandemic on individuals with eating disorders: the role of emotion regulation and exploration of online treatment experiences

OBJECTIVE

The Covid-19 pandemic has wrought disruption to everyday life and services, and emerging evidence suggests that those with eating disorders (EDs) are likely to experience marked distress and exacerbation of their symptoms. However, little is known around the most relevant factors to symptom change; whether certain emotion regulation and coping strategies are linked to better outcomes; and how people with EDs are adjusting to psychological interventions moving online.

METHOD

In a mixed-method design, we collected qualitative and quantitative data from 207 (76 males) self-selected UK residents with self-reported ED, who described and ranked impacts of the pandemic on their symptoms. Regression analysis examined whether emotion regulation strategies were associated with self-reported symptom change, ED symptomatology, and negative emotional states. Thematic analysis explored participants' experiences of the pandemic, particularly factors affecting their ED, coping strategies used, and experiences of psychological intervention.

RESULTS

Most participants (83.1%) reported worsening of ED symptomatology, though factors affecting symptom change differed between specific EDs. Emotion regulation, such as having fewer strategies, poorer emotional clarity, and non-acceptance of emotions, explained nearly half of the variance in emotional distress during the pandemic. Qualitative findings indicated that difficult emotions (such as fear and uncertainty), changes to routine, and unhelpful social messages were triggering for participants during the pandemic. While some participants described employing positive coping strategies (such as limiting social media exposure), many reported using ED behaviours (among other maladaptive strategies, like alcohol use) to cope with the pandemic. Finally, loss of treatment support, feeling underserving of support and experiencing a 'detached connection' online were further exacerbating factors for these participants.

DISCUSSION

While our sample was self-selected and may not represent all people with EDs, our results suggest that people with EDs have been strongly affected by the pandemic. Some aspects of online treatment were found to be beneficial but our findings suggest it also needs some improvement. Our paper discusses implications for online treatment such as taking into account personal circumstances and, in a time where people have limited control over the antecedents of negative emotion, the need to develop skills to manage emotions when they arise.

Motivation-Enhancing Psychotherapy for Inpatients With Anorexia Nervosa (MANNA): A Randomized Controlled Pilot Study

Patients with anorexia nervosa (AN) are frequently characterized by an unstable readiness to change and high ambivalence toward treatment. Enhancing readiness to behavioral change therefore plays an essential role for adherence to treatment especially for severely ill patients treated in inpatient settings. Therefore, a novel 10 week program for the individual psychotherapy sessions was designed using elements from motivational interviewing to be applied within the multidisciplinary inpatient treatment for patients with AN. In a randomized controlled pilot trial, N = 22 patients with AN received either the new intervention or treatment as usual in one of two recruiting university hospitals. Readiness to change, eating disorder pathology, therapeutic alliance as well as acceptance and feasibility of the new intervention were measured from patients and therapists in week 1, 5, and 10 of inpatient treatment. Results confirm acceptance and feasibility of the MANNA intervention as evaluated by patients as well as therapists. Patients receiving the new intervention completed their inpatient treatment significantly more often on regular terms than patients receiving treatment as usual. No differences between the groups could be found concerning therapeutic alliance during and at the end of treatment and readiness to change. Absolute numbers of BMI increase indicate a larger increase in the intervention group albeit not significant in this pilot study sample. Limitations of the study such as the small sample size as well as possible adaptions and advancements of the intervention that need to be examined in a larger clinical trial of efficacy are discussed. This phase II study is registered with the German Clinical Trials Register (DRKS) under the trial number DRKS00015639.

Latent trajectories of eating disorder treatment response among female patients in residential care

OBJECTIVE

Eating disorder (ED) treatment outcomes are highly variable from beginning to end of treatment; however, little is known about differential trajectories during the course of treatment. This study sought to characterize heterogeneous patterns of ED treatment response during residential care.

METHOD

Participants were adolescent girls and adult women (N = 360) receiving residential ED treatment for anorexia nervosa, bulimia nervosa, binge-eating disorder, other specified feeding or eating disorder, unspecified feeding or eating disorder, or avoidant/restrictive food intake disorder. Self-report symptom assessments were completed at admission, discharge, and approximately weekly throughout the residential stay to assess curvilinear patterns of change. Latent growth mixture modeling was applied to identify subgroups of patients with similar treatment response trajectories.

RESULTS

Three latent groups emerged, including gradual response (58.3%; steady improvements from admission to discharge), rapid response (23.9%; steep early improvements that were maintained through discharge), and low-symptom static response (17.8%; nearly nonclinical self-reported symptoms at admission that remained static through discharge). Groups differed on important clinical characteristics, such as body mass index, endorsement of compensatory behaviors, severity of global ED psychopathology at admission, and degree of symptom improvement by end of treatment.

DISCUSSION

Patients follow heterogeneous response patterns in residential ED treatment, and these patterns are associated with differential treatment outcome. Future work should explore whether these trajectories are associated with differential outcomes at follow-up and whether tailoring clinical intervention to a patient's trajectory type can improve treatment response.

Development and validation of the schedule for the assessment of insight in eating disorders (SAI-ED)

This study examined the reliability, validity and internal structure of the newly developed, interview-based Schedule for the Assessment of Insight in Eating Disorders (SAI-ED) and the relationships of insight with demographic and clinical characteristics in EDs. Ninety-four female patients - 44 with anorexia nervosa (AN) and 50 with bulimia nervosa (BN) - were assessed with SAI-ED. The Brown Assessment of Beliefs Scale was used to evaluate convergent validity of SAI-ED. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships. The final 8-item SAI-ED demonstrated good psychometric properties. Inter-rater and test-retest reliabilities were high. Three subscales of SAI-ED were identified which measure major insight components: awareness of illness, awareness of symptoms, and treatment engagement. Patients with AN had significant lower score on SAI-ED than patients with BN. Impaired insight was associated with: (a) lower current and lowest lifetime BMI and more severe dietary restrain in AN, (b) illness duration, severity of overall ED symptoms, body-related concerns and obsessionality in BN. Insight is a multidimensional construct in EDs associated with different clinical aspects in AN and BN. The SAI-ED is a valid and reliable tool for the assessment of insight in EDs patients.

Eating and exercise behaviors in eating disorders and the general population during the COVID-19 pandemic in Australia: Initial results from the COLLATE project

OBJECTIVE

Emerging evidence suggests that the coronavirus (COVID-19) pandemic may be negatively impacting mental health. The impact on eating and exercise behaviors is, however, currently unknown. This study aimed to identify changes in eating and exercise behaviors in an Australian sample among individuals with an eating disorder, and the general population, amidst the COVID-19 pandemic outbreak.

METHOD

A total of 5,469 participants, 180 of whom self-reported an eating disorder history, completed questions relating to changes in eating and exercise behaviors since the emergence of the pandemic, as part of the COLLATE (COvid-19 and you: mentaL heaLth in AusTralia now survEy) project; a national survey launched in Australia on April 1, 2020.

RESULTS

In the eating disorders group, increased restricting, binge eating, purging, and exercise behaviors were found. In the general population, both increased restricting and binge eating behaviors were reported; however, respondents reported less exercise relative to before the pandemic.

DISCUSSION

The findings have important implications for providing greater monitoring and support for eating disorder patients during the COVID-19 pandemic. In addition, the mental and physical health impacts of changed eating and exercise behaviors in the general population need to be acknowledged and monitored for potential long-term consequences.

Peer mentoring for individuals with an eating disorder: a qualitative evaluation of a pilot program

BACKGROUND

After receiving intensive medical treatment; individuals with eating disorders often require ongoing care to maintain their recovery, build social networks, and reduce risk of relapse.

METHODS

To address this important transition period, a six-month peer mentoring program was developed and piloted in Melbourne, Australia. Twelve adults with a past history of an eating disorder (mentors) were paired with 14 individuals with a current eating disorder (mentees). Pairs met for thirteen mentoring sessions in community settings. Throughout the program mentees and mentors completed reflective questions online. Upon completion of the program, qualitative interviews were conducted. Both online reflections and interviews explored themes relating to perceived benefits and challenges of participation in the peer mentoring program, and the differences between mentoring and traditional treatment.

RESULTS

Thematic analysis identified several benefits for mentees; including hope, reconnection with others, and re-engaging with the world. The majority of mentees described their mentor as uniquely supportive due to their past experience of an eating disorder. Mentors reported experiencing benefits such as increased connection with self and others, and indicated that the experience helped them positively reframe their past experience of an eating disorder. Ending the relationship at the completion of the program was a significant challenge for both groups, and managing boundaries was deemed a main challenge by mentors.

CONCLUSIONS

Overall, results indicated that this mode of informal support may be worthy of further investigation as an adjunct to clinical treatment programs for this population.

Case report: cognitive performance in an extreme case of anorexia nervosa with a body mass index of 7.7

BACKGROUND

Studies show that adult patients with anorexia nervosa display cognitive impairments. These impairments may be caused by illness-related circumstances such as low weight. However, the question is whether there is a cognitive adaptation to enduring undernutrition in anorexia nervosa. To our knowledge, cognitive performance has not been assessed previously in a patient with anorexia nervosa with a body mass index as low as 7.7 kg/m2.

CASE PRESENTATION

We present the cognitive profile of a 35-year-old woman with severe and enduring anorexia nervosa who was diagnosed at the age of 10 years. She was assessed with a broad neuropsychological test battery three times during a year. Her body mass index was 8.4, 9.3, and 7.7 kg/m², respectively. Her general memory performance was above the normal range and she performed well on verbal and design fluency tasks. Her working memory and processing speed were within the normal range. However, her results on cognitive flexibility tasks (set-shifting) were below the normal range.

CONCLUSIONS

The case study suggests that it is possible to perform normally cognitively despite extreme and chronic malnutrition though set-shifting ability may be affected. This opens for discussion whether patients with anorexia nervosa can maintain neuropsychological performance in spite of extreme underweight and starvation.

Subjective evaluation of outpatient treatment for adolescent patients with anorexia nervosa

BACKGROUND

The current study investigates determinants of treatment evaluation by adolescent outpatients with anorexia nervosa (AN) and the accordance with their parents' and psychotherapists' evaluation.

SAMPLING AND METHODS

The sample included 50 female adolescent outpatients (mean age: 16.9 ± 1.8) with AN (DSM-IV). They were randomly assigned to either cognitive-behavior therapy (CBT) or dialectical-behavior therapy (DBT). Before (T1) and after treatment (T2) diagnostic interviews as well as self-report questionnaires were administered measuring eating disorder-specific and general psychopathology. The subjective evaluation of the therapy was assessed by a self-report questionnaire. Data on the evaluation of treatment of 42 parents were considered as well as treatment evaluations of the therapists for 48 patients.

RESULTS

Our results revealed significant correlations of treatment satisfaction between parents and therapists, whereas patients and therapists as well as patients and parents did not agree in their treatment evaluation. The change in body mass index (BMI) was a significant predictor of the patients' treatment satisfaction.

CONCLUSION

Adolescent patients displaying high severity of AN at the beginning of treatment put little emphasis on the importance of body weight even after treatment. Satisfaction ratings of this special group of patients could be heavily distorted and have to be interpreted carefully.

Naturalistic follow-up of subjects affected with anorexia nervosa 8 years after multimodal treatment: Personality and psychopathology changes and predictors of outcome

Background:

Eating disorders (EDs) are serious mental illnesses of growing clinical and social impact. Despite their severity, there is still no satisfactory evidence-based treatment. Follow-up investigations are the most reliable studies to enlighten long-term outcome predictors and modifiers.

Methods:

In total, 59 subjects affected with anorexia nervosa were assessed 8 years after their admission into an outpatient multimodal treatment program for eating disorders. The follow-up changes in diagnostic criteria were compared with Chi-square test. Improved and not-improved subjects were compared. Clinical, personality and psychopathology features between T0 and T1 were compared with t-test for repeated measures. Correlation between T0 features and changes at T1 in personality and psychopathology features were assessed.

Results:

The rate of complete remission was 42%, an overall rate of 67.8% improved, a rate of 18.6% worsened. Concerning personality, a significant decrease of harm avoidance and increase in self-directedness were evidenced. Interoceptive awareness, drive for thinness, bulimia were significantly reduced at follow-up. Many T0 personality facets were related to personality and psychopathology improvement at follow-up.

Conclusion:

Multimodal treatment encompassing psychiatric, nutritional and psychological approaches is at the moment the most reliable approach for the treatment of moderate to severe anorexia nervosa with a discrete rate of improvement. Some personality and psychopathology characteristics may represent specific factors which favor resistance and impair improvement. Future approaches should consider the personalization of therapeutic approach according to these features.

Eating Disorder Recovery: A Metaethnography

BACKGROUND: Eating disorders seriously affect both physical health and psychosocial functioning. Breaking the confines of an eating disorder requires engagement in a multifaceted recovery process. OBJECTIVE: This article provides a synthesis of 12 qualitative research studies with various eating disordered populations (anorexia nervosa, bulimia nervosa, binge eating disorder, eating disorder not otherwise specified, and other specified feeding and eating disorders) to elucidate the recovery process from the perspective of those who have overcome the disease. METHOD: A metasynthesis of qualitative studies was conducted using Noblit and Hare's metaethnographic methodology. RESULTS: Five overarching themes emerged from the data: (1) the eating disorder as a life jacket, (2) drowning: recognizing consequences, (3) treading the surface: contemplating recovery, (4) swimming: the path toward recovery, and (5) reaching recovery: a sense of freedom. CONCLUSIONS: Eating disorder treatment often entails a cycle of transitions before recovery occurs. Synthesizing the experiences from the perspective of individuals who have overcome an eating disorder presents a unique understanding of the treatment and recovery process.

Prominent autistic traits and subthreshold bipolar/mixed features of depression in severe anorexia nervosa

OBJECTIVE

Autistic traits are associated with a burdensome clinical presentation of anorexia nervosa (AN), as is AN with concurrent depression. The aim of the present study was to explore the intertwined association between complex psychopathology combining autistic traits, subthreshold bipolarity, and mixed depression among people with AN.

METHOD

Sixty patients with AN and concurrent major depressive episode (mean age, 22.2±7 years) were cross-sectionally assessed using the Autism-Spectrum Quotient test (AQ-test), the Hamilton depression scales for depression and anxiety, the Young Mania Rating Scale (YMRS), the Hypomania-Checklist-32 (HCL-32), second revision (for subthreshold bipolarity), the Brown Assessment and Beliefs Scale (BABS), the Yale-Brown-Cornell Eating Disorders Scale (YBC-EDS), and the Eating Disorder Examination Questionnaire (EDE-Q). Cases were split into two groups depending on body mass index (BMI): severe AN (AN+) if BMI < 16, not severe (AN-) if BMI ≥ 16.

RESULTS

The "subthreshold bipolarity with prominent autistic traits" pattern correctly classified 83.6% of AN patients (AN+ = 78.1%; AN- = 91.3%, Exp(B) = 1.391). AN+ cases showed higher rates of positive scores for YMRS items 2 (increased motor activity-energy) and 5 (irritability) compared to AN- cases.

CONCLUSIONS

In our sample, depressed patients with severe AN had more pronounced autistic traits and subtly mixed bipolarity. Further studies with larger samples and prospective follow-up of treatment outcomes are warranted to replicate these findings.

Histone deacetylase 4 (HDAC4): a new player in anorexia nervosa?

Anorexia nervosa (AN) and other eating disorders continue to constitute significant challenges for individual and public health. AN is thought to develop as a result of complex interactions between environmental triggers, psychological risk factors, sociocultural influences, and genetic vulnerability. Recent research developments have highlighted a novel potentially relevant component in the AN etiology-activity of the histone deacetylase 4 (HDAC4) gene that has emerged in several recent studies related to AN. HDAC4 is a member of the ubiquitously important family of epigenetic modifier enzymes called histone deacetylases and has been implicated in processes related to the formation and function of the central nervous system (CNS), bone, muscle, and metabolism. In a family affected by eating disorders, a missense mutation in HDAC4 (A786T) was found to segregate with the illness. The relevance of this mutation in eating-related behaviors was further confirmed with mouse models. Despite  the fact that HDAC4 has not been identified as a significant signal in genome-wide association studies in AN, several studies have found significant or near-significant methylation differences in HDAC4 locus in peripheral tissues of actively ill AN patients in comparison with different control groups. Limitations of these studies include a lack of understanding of to what extent the changes in methylation are predictive of AN as such changes might also occur as a consequence of the disease. It remains to be determined how methylation in peripheral tissues correlates with that in the CNS and how different methylation patterns affect HDAC4 expression. The present review discusses the findings and potential roles of HDAC4 in AN. Its emerging roles in learning and neuroplasticity may be specific and relevant for the etiology of AN and potentially lead to novel therapeutic approaches.

The unsafe haven: Eating disorders as attachment relationships

OBJECTIVES

Some patients with eating disorders (EDs) seem to experience their illness as an entity, a symbolic other to whom they relate, and which may influence both symptom levels and self-image. Extending previous research, this study investigated whether the patient-ED relationship has attachment qualities.

DESIGN

Structural Analysis of Social Behaviour was used to operationalize the patient-ED relationship, and the Attachment Style Questionnaire was used to measure attachment.

METHOD

We examined ED patients' (N = 148) relationship with their ED, attachment behaviour, symptoms, and self-image. Attachment dimensions of Confidence, Anxious/ambivalence, and Avoidance were found to be significantly correlated with aspects of the patient-ED relationship. Introjection (i.e., whether ED actions were incorporated into patients' self-image) was investigated by examining the match between self-image profiles and the actions of patients' EDs. A double mediation model was tested in which ED control/emancipation and patients' Self-blame mediated the effect of attachment security on ED symptoms.

RESULTS

Attachment insecurity was associated with greater ED control and patient submission. In 28.5% of patients, there was a high degree of correlation between self-image and ED action profile. Data supported the mediation model.

CONCLUSIONS

Attachment processes appear to be associated with the manner in which ED patients relate to their disorder, at least in some cases. Attempts to maintain psychological proximity to the ED as an introjected attachment figure may help to explain treatment resistance and ambivalence about change. This perspective may be useful in treatment.

PRACTITIONER POINTS

Attachment behaviours are associated with the patient-ED relationship, in which attachment insecurity is correlated with greater eating disorder control and patient submission. Some patients seem to incorporate the actions of the ED in their self-image, suggesting the presence of introjection. The patient-ED relationship may help explain patients' anxiety and ambivalence about change, seen from an attachment perspective. In treatment, it may be important to explore alternative safe havens and secure bases to the ED, such as interpersonal relationships and activities.

Perceptions of the "anorexic voice": A qualitative study of health care professionals

People with anorexia nervosa (AN) often report experiencing a highly critical inner voice (AV) focused on their eating, shape, and weight. There are promising preliminary findings for its role in the treatment of AN, and the support of staff is vital for the AV to be embedded in treatment, but their views remain unknown. The aims of this study were to undertake a qualitative exploration of the perceptions of the AV among health care professionals (HCPs) in specialist eating disorder services. A thematic analysis was applied to interviews with 15 HCPs, including nurses, therapists, psychiatrists, health care assistants, psychologists, and dietitians. Two overarching themes were identified: "The AV is a vehicle for increasing compassion" and "It's not a one-size-fits-all." The AV was seen as a means of developing and sustaining compassion, but participants noted that it does not resonate for all clients. All HCPs in this study believed that there was potential benefit in utilizing the AV in their work with people with AN, and it is likely that doing so would help to reduce burnout and frustration within clinical teams.

Characteristics of patients in an eating disorder sample who dropped out: 2-year follow-up

OBJECTIVE

This manuscript explores the characteristics of individuals diagnosed with an eating disorder who dropped out of treatment, compared with those who completed it.

METHOD

The participants were 196 patients diagnosed with eating disorders (according to DSM-IV-TR criteria) who consecutively began treatment for the first time in an eating disorders unit. They were assessed at baseline with a set of questionnaires evaluating eating habits, temperament, and general psychopathology. During the follow-up period, patients who dropped out were re-assessed via a telephone interview.

RESULTS

In the course of a 2-year follow-up, a total of 80 (40.8%) patients were labeled as dropouts, and 116 (59.2%) remaining subjects were considered completers. High TCI scores in the character dimensions of Disorderliness (NS4) (p < .01) and total Novelty Seeking (NST), along with low scores in Dependency (RD4), were significantly associated with dropout in the course of 2 years. Once the results were submitted to logistic regression analysis, dropout only remained associated with high scores in Disorderliness (NS4) and, inversely, with an initial Anorexia Nervosa (AN) diagnosis (p < .05). Reasons for dropout stated by the patients included logistic difficulties, subjective improvement of their condition, and lack of motivation.

DISCUSSION

Clinicians should handle the first therapeutic intervention with particular care in order to enhance their understanding of clients and their ability to rapidly identify those who are at risk of dropping out of treatment.

Willingness of individuals with eating disorders to participate in health research

BACKGROUND/AIMS

This study examines the association between eating disorders (EDs) and willingness to participate in health research studies among community members.

MATERIALS & METHOD

Data were collected from Health Street, a University of Florida community engagement initiative which aims to reduce disparities in healthcare and health research by direct engagement of community members.

RESULTS

Among 8,226 community members, 3.9% (n = 324) reported a lifetime ED. For all six types of health research studies queried, individuals with a lifetime ED reported a higher willingness to participate in health research compared to individuals without a history. After adjusting for selected covariates, individuals with ED were significantly more likely than individuals without ED to say they would be willing to volunteer for research studies that: ask questions about health (OR: 7.601, 95% CI: [1.874, 30.839]); require an overnight stay in a hospital (OR: 2.041, 95% CI: [1.442, 2.889]); and provide no remuneration (OR: 1.415, 95% CI: [1.022, 1.958]). Furthermore, when compared to individuals with anxiety or depression, individuals with ED reported increased interest in research participation and increased willingness to participate in most types of research studies assessed. After stratifying by gender and race, we observed few differences in willingness to participate in research among individuals with ED.

DISCUSSION

These findings contribute to our current understanding of participant recruitment and enrollment in ED health research. Underrepresented populations who often do not seek treatment for EDs endorsed a high willingness to participate.

CONCLUSION

Future studies will likely benefit from including community members in ED research.

Psychological Meanings of Eating Disorders and Their Association With Symptoms, Motivation Toward Treatment, and Clinical Evolution Among Outpatients

Unlike patients suffering from egodystonic disorders, people with eating disorders sometimes attribute positive meanings to their symptoms, and this attribution process contributes to the maintenance of the disorder. This study aims at exploring psychological meanings of eating disorders and their associations with symptoms, motivation toward treatment, and clinical evolution. Eighty-one adults with an eating disorder (anorexia nervosa, n = 46 and bulimia nervosa, n = 35) treated in a day-hospital program were asked, each week over an 8-week period, to identify the psychological meanings they ascribed to their eating disorder. Avoidance was the most frequently identified meaning, followed by mental strength, security, death, confidence, identity, care, and communication. Avoidance was more frequently mentioned by participants with bulimia than in cases of anorexia. Security and mental strength were associated with less motivation toward treatment. Death was associated with more depressive and anxious symptoms. An exploratory factor analysis showed that these meanings formed three main dimensions: Avoidance, Intrapsychic, and Relational. Findings suggest that psychological meanings associated with eating disorders can be assessed and used as a clinical tool to increase treatment acceptability and effectiveness.

Pathways to specialist care for eating disorders: An Italian multicentre study

Two hundred forty six patients with eating disorders (EDs) recruited from eight Italian specialized treatment centres were administered with the World Health Organization "Encounter Form," a standardized schedule that makes it possible to characterize the clinical pathways that patients follow to reach specialized care. The median time from symptoms onset to specialized care was 114 weeks. Primary "points of access to care" were general practitioners (25%), psychiatrists (18%), and clinical nutritionists (17%), followed by various other carers. All patients received specific psychotherapy, whereas only 11% of them were given psychotropic drugs. EDs are characterized by complex care pathways, with low rates of direct access to specialized care. Although the role of general practitioners remains crucial, they tend to follow different clinical routes to refer ED patients. Educational programmes on EDs should be addressed to general practitioners and clinical nutritionists, in order to ease the transition of ED patients to a mental health care setting.
