Lived experience perspectives on eating disorder research: The use of adaptive trials and research priorities.

This novel study sought to understand lived experience and carer perspectives on the use of adaptive trials to evaluate interventions for eating disorders, in addition to understanding the factors and outcomes of most importance in eating disorder research and treatments from a lived experience perspective. A total of 73 people with either lived or carer experience consented, 70 started the questionnaire, and 36 (51%) completed all questions. Participants were asked Likert scale and open-ended questions to understand what factors and outcomes of eating disorder interventions were most important to them and understand their pre-existing knowledge of clinical trials. Two videos were then used to explain randomized controlled trials (RCTs) and adaptive trials and participants were asked their opinions, including perceived benefits and concerns, of each trial type. The thematic analysis found two key themes regarding factors important in eating disorder treatment: Person-centred care and Evidence-based and effective treatment; and two key themes regarding outcomes of treatment: Sustained, full recovery and The bigger picture. Both RCTs and adaptive trials were viewed favorably, however, there was a slight preference for adaptive trials. Key themes for both demonstrated perceived benefits and ethical, practical, and scientific considerations unique to each. Findings demonstrate the support of adaptive trials in eating disorder interventions from people with lived experience and their carers. It is recommended that researchers consider the use of adaptive designs and the incorporation of lived experience perspectives when designing future intervention trials. This novel study found that the use of adaptive trials in eating disorder intervention research is supported by people with lived experience and carers. Furthermore, the factors and outcomes of most importance to participants in this study are comparable to those previously identified in the emerging literature. The use of adaptive designs and the incorporation of lived experience are recommended in further clinical trials.

Expectations of a new eating disorder treatment and its delivery: Perspectives of patients and new therapists.

A significant number of people with bulimia nervosa (BN) or binge-eating disorder (BED) do not seek professional help. Important reasons include limited knowledge of eating disorders (EDs), feelings of shame, treatment costs, and restricted access to specialized healthcare. In this study, we explored if a novel therapy delivered in a primary care setting could overcome these barriers. We investigated factors such as motivation and expectations and included the patients' and newly trained therapists' perspectives. We interviewed 10 women with BN (n = 2) or BED (n = 8), enrolled in the Physical Exercise and Dietary therapy (PED-t) program, in a Healthy Life Center (HLC) located in a primary healthcare facility. Interview topics discussed were motivations for and expectations of therapy, and the treatment location. In addition, 10 therapists from HLC's were interviewed on their experiences with the PED-t training program and expectations of running PED-t within their service. The semi-structured interviews were analyzed using reflexive thematic analysis. Most patients had limited knowledge about EDs and first realized the need for professional help after learning about PED-t. Patients exhibited strong motivations for treatment and a positive perception of both the PED-t, the new treatment setting, and the therapists' competencies. The therapists, following a brief training program, felt confident in their abilities to treat EDs and provide PED-t. With minor operational adjustments, PED-t can seamlessly be integrated into national HLC service locations. PED-t is an accessible therapeutic service that can be delivered in a primary care environment in a stepped-care therapy model. This study investigates the views and experiences of patients and newly trained therapists of PED-t (Physical Exercise and Dietary therapy), a new program-led primary care therapy for binge-eating spectrum eating disorders. The treatment and the locations for the intervention, that is, local health care centers, were found to be highly acceptable to both patients and therapists, thus PED-t could easily be integrated as a first step into a step-care delivery model.

Nutritional considerations for gender-diverse people: a qualitative mini review.

Dietitians working with gender-diverse people may require different skills and knowledge than those caring for cisgender men and women, as indicated by a growing body of literature that highlights gender-diverse people's unique experiences with and relationships to nutrition and eating behaviors. To provide insight into how dietitians can best serve this population, this mini review identifies and summarizes qualitative studies that investigate gender-diverse people's lived experiences and perspectives regarding nutrition, eating disorders, and access to eating-related healthcare services. Fourteen studies examining nutrition or eating behaviors among gender-diverse samples were selected through a systematic search and screening process: 11 focused on disordered eating or eating disorders and the remaining three focused on nutritional needs, nutritional knowledge, and food insecurity. Extracted themes included: using dietary restriction to suppress secondary sex characteristics or conform to societal norms; the impact of gender-affirming care on disordered eating; negative experiences with, and beliefs about, nutrition and eating disorders healthcare services; and suggestions for clinicians. Recommendations discuss the need for increased trans literacy among clinicians, the creation of safe spaces for gender-diverse people with eating disorders, and the importance of dual competencies in eating disorders treatment and gender-affirming care.

“It’s beautiful and it’s messy and it’s tragic”: exploring the role of compassion in the eating disorder recovery processes of 2S/LGBTQ + Canadians

This research explores experiences of compassion among 2S/LGBTQ + Canadians living with eating disorders in the context of eating disorder treatment and community support. There is a growing body of scholarship showing disparities in eating disorder care for those within 2S/LGBTQ + communities. Among the reported concerns is a potential lack of compassion in eating disorder treatment and recovery settings, something which may serve to exacerbate feelings of isolation and perpetuate misunderstandings of 2S/LGBTQ + people’s experiences. In an effort to understand these dynamics more deeply, we conducted semi-structured interviews with 2S/LGBTQ + Canadians who have experienced eating disorder care. The data collected were then subjected to Foucauldian discourse analysis, which produced three interconnected discursive considerations: feeling lack of structural compassion, 2S/LGBTQ + communities as places of respite, and 2S/LGBTQ + caregiving. One of the common threads among these discursive considerations was cis-heteronormativity ingrained in eating disorder treatment settings and health care systems more broadly. Our findings underscore the critical need for more enhanced compassion for 2S/LGBTQ + patients in eating disorder care settings. We conclude that compassion, when implemented on the levels of individual clinicians, policy and procedure, and institutions, may represent an avenue toward disrupting ingrained cis-heteronormativity and the associated discursive power structures contained in health care systems.

Introducing a Smart Toy in Eating Disorder Treatment: A Pilot Study.

Individuals with eating disorders (EDs) often encounter challenges related to body image, emotional, and sensory difficulties during nutritional rehabilitation. To address these challenges, a novel technology-enabled smart toy, Purrble, designed for immediate assistance in emotion regulation, is being explored. A mixed-method approach involving workshops, diaries, and focus groups was employed to examine the feasibility of Purrble as a therapeutic tool and its impact on participants' daily routines, sensory experiences, and emotional states. The study results demonstrate the engagement and acceptability of this device. Qualitative analysis revealed that participants independently used and integrated Purrble into their emotional and sensory regulation practices. These pilot results support the potential for a shift in the delivery of adjunct therapeutic tools through technology, particularly for ED patients with complex presentations. Future research is necessary to further explore the psychological benefits of this intervention.

Mental health facilities with eating disorder treatment programs and substance use disorder treatment in the United States

ABSTRACT Eating disorders (EDs) and substance use disorders (SUDs) often co-occur. However, not all providers that treat persons with an ED provide SUD treatment. Using the National Mental Health Services Survey, this study examined 1,387 ED treatment providers in the U.S. Facilities were categorized according to whether they provided SUD treatment. Differences based on facilities’ profit status, available treatment settings, payment options, and treatment services were examined. Most ED facilities in the sample offered SUD treatment services (67.2%). Differences in proportions of the facility type, availability of outpatient treatment, sliding fee scale payment option, whether the facility had a program for individuals with co-occurring mental health and SUD, couples/family therapy, dual disorders treatment, and if the facility provided telemedicine/telehealth were identified. Although most facilities in this sample offered SUD services, more should be done to increase such facilities’ capacity to provide treatment for co-occurring ED and SUD nationwide.

State mechanisms of change in eating disorder symptoms and fears during an online imaginal exposure treatment for eating disorders

Anxiety and fear are key characteristics of eating disorders (EDs). Exposure therapy is a specific type of intervention aimed at reducing fear and anxiety and is efficacious in treating a variety of anxiety and related disorders. A growing body of research suggests that exposure therapy is also efficacious for the treatment of EDs. However, there is currently little research investigating mechanisms of change during exposure therapy for EDs. The current study (N = 143) expanded on an open series trial of imaginal exposure for EDs that found significant reductions in ED symptoms and core ED fears. In the current study we investigated change in state drive for thinness, body dissatisfaction, and anxiety as mechanisms underpinning change in ED symptoms and core ED fears during four sessions of online imaginal exposure treatment for EDs. We found that state body dissatisfaction, but not state drive for thinness or anxiety, was a mechanism of change for ED symptoms and some core ED fears. Our findings suggest that body dissatisfaction may be a mechanism driving change during exposure therapy for EDs. Optimizing exposure treatments to focus on body dissatisfaction may improve treatment outcomes for EDs.

Mental health providers' perceptions of restrictive eating disorders: Relationship with client body weight.

This study investigated whether mental health providers have different diagnostic impressions and treatment recommendations for patients with restrictive eating disorders, depending on the patient's body weight. Participants were given one of three versions of a vignette depicting a patient who meets DSM-5 criteria for anorexia nervosa (AN) or atypical AN with the patient's weight described as either below, within, or above the average range for her age and height. Participants were then asked to respond to a series of questions about diagnosis, symptoms, and treatment recommendations. Results were compared between the three weight conditions with the goal of better understanding how a patient's body weight may influence different aspects of participants' clinical impressions. Participants given the low weight version of the vignette were more likely to identify the presenting problem as an eating disorder and to agree that the patient experienced dietary restriction and weight loss, weight gain avoidance, and body image concerns. Participants given the low weight description were also more likely to recommend specialized eating disorder treatment and medical follow-up. Findings suggest that mental health providers were generally more responsive to restrictive eating disorder symptoms when the patient was at a lower body weight. These results are concerning because they suggest patients with atypical AN may be less likely to receive an accurate diagnosis or adequate treatment compared to underweight patients with AN, despite experiencing the same symptoms. Restrictive eating disorders like AN and atypical AN can cause comparable physical and psychological symptoms in people of any body weight. Despite having the same symptoms, people with a higher body weight are less likely to receive a diagnosis or treatment. This study compared mental health providers' reactions to a description of a patient with an eating disorder at different body weights and found differences in diagnosis, detection of symptoms, and treatment recommendations.

Therapeutic alliance with psychotherapist versus dietician: a pilot study of eating disorder treatment in a multidisciplinary team during the COVID-19 pandemic.

Little is known about the therapeutic alliance (TA) formed with different professionals in multidisciplinary eating disorder (ED) treatment, particularly in the context of online treatment during the COVID-19 pandemic. We aimed to conduct a pilot study during the COVID-19 pandemic examining characteristics of patients' TA with their dieticians and psychotherapists, associations between patients' and therapists' views of the TA, and relationships between psychological characteristics and TAs. Sixty-three patients with EDs and their treating psychotherapists and dieticians were surveyed during the COVID-19 pandemic using the Working Alliance Inventory (WAI-S). Spearman correlation tests were used to examine associations between variables. Positive associations were found between the TAs examined. Concordance was stronger in patient-dietician dyads than in patient-psychotherapist dyads. Severe ED psychopathology was associated with weaker TA (bond subscale). General psychopathology was associated with weaker TA with the dietician (task subscale). Given that several differences were found between the TAs of treatment dyads, further longitudinal studies are needed to validate our pilot findings and to investigate multidisciplinary TAs and their impact on treatment outcomes in online ED treatment settings during the COVID-19 pandemic, as well as in other treatment settings (e.g., in-person settings). This study will contribute to a deeper understanding of the dynamics of TAs in multidisciplinary ED treatment and inform the development of more effective interventions.

Clinical characterization of Co-morbid autoimmune disease and eating disorders: a retrospective chart review

ABSTRACT Research suggests a link between autoimmune illnesses (AI) and eating disorders (ED). We retrospectively reviewed charts of adolescent patients presenting for eating disorder treatment. We compared the presentation and treatment course for those with an ED and comorbid AI [with (GI-AI, N = 59) or without (non-GI, N = 21) gastrointestinal inflammation] with matched ED-only cases. The sample was overwhelmingly female, with an average age of 15.40. Weight gain trajectories differed across groups, with similar rates of weight gain between controls and non GI-AI cases and with a lower rate of weight gain for individuals with comorbid GI-AI. Over half (56%) of patients reported an AI diagnosis prior to ED; 38% reported an AI diagnosis following ED, and 6% reported ED and AI simultaneous diagnosis. On presentation, ED-only controls had higher rates of comorbid anxiety than cases in either AI group, while those with non-GI AI were more likely to report depression. Mean total GI symptoms, % goal weight at presentation, vital sign instability, and markers of refeeding syndrome did not differ across groups. Health care professionals treating patients with either condition should have a low threshold for asking additional questions to identify the presence of the other condition.

Promoting Resilience to Improve Disordered Eating (PRIDE): A case series of an eating disorder treatment for sexual minority individuals.

Despite the increased risk for eating disorders (EDs) among sexual minority (SM) individuals, no ED treatments exist specifically for this population. SM stress and appearance-based pressures may initiate and/or maintain ED symptoms in SM individuals; thus, incorporating strategies to reduce SM stressors into existing treatments may help address SM individuals' increased ED risk. This mixed-methods study evaluated the feasibility, acceptability, and preliminary efficacy of Promoting Resilience to Improve Disordered Eating (PRIDE)-a novel ED treatment for SM individuals. N = 14 SM individuals with an ED diagnosis received 14 weekly sessions integrating Enhanced Cognitive Behavioral Therapy for EDs (CBT-E) with techniques and principles of SM-affirmative CBT developed to address SM stressors. Participants completed qualitative interviews and assessments of ED symptoms and SM stress reactions at baseline (pretreatment), posttreatment, and 1-month follow-up. Supporting feasibility, 12 of the 14 (85.7%) enrolled participants completed treatment, and qualitative and quantitative data supported PRIDE's acceptability (quantitative rating = 3.73/4). By 1-month follow-up, 75% of the sample was fully remitted from an ED diagnosis. Preliminary efficacy results suggested large and significant improvements in ED symptoms, clinical impairment, and body dissatisfaction, significant medium-large improvements in internalized stigma and nonsignificant small-medium effects of sexual orientation concealment. Initial results support the feasibility, acceptability, and initial efficacy of PRIDE, an ED treatment developed to address SM stressors. Future research should evaluate PRIDE in a larger sample, compare it to an active control condition, and explore whether reductions in SM stress reactions explain reductions in ED symptoms. This study evaluated a treatment for SM individuals with EDs that integrated empirically supported ED treatment with SM-affirmative treatment in a case series. Results support that this treatment was well-accepted by participants and was associated with improvements in ED symptoms and minority stress outcomes.

Examining clinicians' perceptions and experiences working with diverse families in family-based treatment: Common adaptations and considerations for treatment engagement.

Family-Based Treatment (FBT) is the leading manualized treatment for adolescent eating disorders; however, there is limited research on the adaptation of FBT for diverse families (i.e., families belonging to identity groups subject to systemic barriers and prejudices). The purpose of this qualitative study was to address: (1) adaptations made to the FBT model (if any) by clinicians working with diverse youth and families; (2) the barriers/facilitators of maintaining adherence (fidelity) to the model for these families; and, (3) the barriers/facilitators to access and engagement in FBT for diverse families. Forty-one FBT clinicians were recruited globally using purposive and snowball sampling, and listservs from eating disorder networks. Clinicians participated in individual interviews or focus groups, discussing their experiences delivering and adapting FBT for diverse families. Qualitative data was transcribed verbatim and analyzed using directed content analysis. Some participants reported making adaptations to every phase of the FBT model, while others did not, when working with diverse families. In Phase 1, participants cited adapting the family meal, length/number of sessions provided, and addressed systemic barriers. In Phase 2, participants adapted the length of the phase and rate/level of independence given back to the adolescent. In Phase 3, participants increased or decreased the number of sessions, or eliminated this phase to address barriers to engagement in FBT. This is the first study to qualitatively examine clinicians' experiences of implementing FBT with diverse families. Results may inform future FBT planning, clinician training, clinical decision-making tools, and opportunities for modifications to the foundational model. This qualitative study examined clinicians' perceptions and experiences implementing FBT with diverse families, specifically what adaptations (if any) were made to the foundational model, and the barriers and facilitators to adhering to and engaging in the model. Results show that some participants reported making adaptations to every phase of FBT, while others did not, with diverse families. Findings may inform future treatment planning, clinician training, clinical decision-making tools, and potential modifications to FBT.

Virtually delivered guided self-help for binge eating disorder and bulimia nervosa: findings from a service evaluation.

Timely intervention is beneficial to the effectiveness of eating disorder (ED) treatment, but limited capacity within ED services means that these disorders are often not treated with sufficient speed. This service evaluation extends previous research into guided self-help (GSH) for adults with bulimic spectrum EDs by assessing the feasibility, acceptability, and preliminary effectiveness of virtually delivered GSH using videoconferencing. Patients with bulimia nervosa (BN), binge eating disorder (BED) and other specified feeding and eating disorders (OSFED) waiting for treatment in a large specialist adult ED out-patient service were offered virtually delivered GSH. The programme used an evidence-based cognitive behavioural self-help book. Individuals were supported by non-expert coaches, who delivered the eight-session programme via videoconferencing. One hundred and thirty patients were allocated to a GSH coach between 1 September 2020 and 30 September 2022; 106 (82%) started treatment and 78 (60%) completed treatment. Amongst completers, there were large reductions in ED behaviours and attitudinal symptoms, measured by the ED-15. The largest effect sizes for change between pre- and post-treatment were seen for binge eating episode frequency (d = -0.89) and concerns around eating (d = -1.72). Patients from minoritised ethnic groups were over-represented in the non-completer group. Virtually delivered GSH is feasible, acceptable and effective in reducing ED symptoms amongst those with bulimic spectrum disorders. Implementing virtually delivered GSH reduced waiting times, offering a potential solution for long waiting times for ED treatment. Further research is needed to compare GSH to other brief therapies and investigate barriers for patients from culturally diverse groups.

A Qualitative Exploration of Prominent Factors Contributing to the Aetiology of Child and Adolescent Eating Disorder Presentations during the COVID-19 Pandemic: The Perspectives of Patients, Parents and Clinicians.

The aim of this study was to explore the prominent factors that contributed to the development of child and adolescent eating disorder presentations during the COVID-19 pandemic. This was achieved through a qualitative analysis of interviews gathered from (1) adolescent patients diagnosed with an eating disorder (ED) during the COVID-19 pandemic (aged 13-18) (n = 4), (2) parents of patients attending an ED service (n = 7) and (3) clinicians working within a specialist child and adolescent ED support service (n = 7). Reflexive thematic analysis was used to analyse the data and establish the most prominent aetiological factors reported. The most prominent aetiological factors reported were (1) the accumulation of risk factors; (2) seeking control amid increased anxiety, stress and uncertainty; (3) social isolation; (4) an increased focus on exercise and "healthy eating"; (5) increased social media use promoting unhelpful attention towards ED triggers; and (6) a lack of both awareness and support services. During the COVID-19 pandemic, the quantity and severity of ED presentations increased. The current study uncovered six themes perceived by patients, parents and clinical staff that contributed to the aetiology of ED presentations during the COVID-19 pandemic. It is hoped that the insight gained through this research study into ED aetiology may act as a basis for further research and support ED awareness, prevention and intervention in the future.

Cutoff scores of the Eating Disorder Examination-Questionnaire for the German population.

The Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report measures for the assessment of eating disorder (ED) symptomatology. However, proposed cutoff scores that may indicate the presence of an ED have been heterogeneous. Therefore, the current study derived cutoff scores from two large samples: one representative for the German population and one composed of persons with EDs at admission to inpatient treatment. Receiver operating characteristic analysis was used with the EDE-Q global score as independent variable and group (controls: n = 2519, patients: n = 2038) as dependent variable. These analyses were also conducted separately with the patient group divided into persons with anorexia nervosa (AN; n = 1456), bulimia nervosa (BN; n = 370), and other EDs (n = 212) and after matching groups for age and sex distribution. The EDE-Q global score discriminated well between controls and patients (AUC >91%, sensitivity >.84, specificity >.79). A score of 1.6 discriminated best between controls and patients in general and persons with AN in particular. Optimal thresholds for discriminating between controls and persons with BN and other EDs ranged between scores of 1.8 and 2.4. In the German population, cutoff scores between 1.6 and 2.4 may be used to screen for the presence or absence of an ED or evaluate treatment outcome, with slightly higher cutoff scores for persons with BN and other EDs than for persons with AN. Questionnaire scores have little value when it is unclear which scores indicate the likely presence of an ED, as such scores can be used to estimate the prevalence of or screen for EDs in the general population and evaluate outcome at the end of ED treatment. The current study indicates a score around 2 on the EDE-Q as an optimal threshold for this.

Early evaluation of a DBT-informed online intervention for people with eating disorders.

Eating disorders (EDs) have a worldwide prevalence of 7.8%, with towering mortality rates and high healthcare costs. The current recommended treatment for EDs principally works by directly targeting ED thoughts and behaviours, but recovery rates are low. A multifaceted link between difficulties with emotions and EDs is now widely established, and newer third-wave therapies that aim to address these underlying emotion difficulties are promising. The current study piloted an onlineemotion self-help intervention which was co-developed with clinicians and people with lived experienced of EDs. The intervention aimed to specifically address difficulties with emotion identification and regulation, as well as unhelpful beliefs about emotions, which are believed to give rise to and maintain ED thoughts and behaviours. We recruited 39 people with self-reported EDs to test this intervention over a one-week period. Our participants were asked to complete a series of questionnaires measuring emotion processes and psychopathology on Day 1 (T1) before being given access to the intervention. Participants were then asked to practice the newly acquired skills for seven days, before taking the same questionnaires on Day 9 (T2). We also asked participants to qualitatively report on their experience of the intervention. We found significant improvements in ED psychopathology (ED-15), depression (PHQ-9), and anxiety (GAD-7) pre- to post-intervention, with medium to large effect sizes. All our emotion variables namely alexithymia (TAS-20), difficulties regulating emotions (DERS-SF), and unhelpful beliefs about emotions (EBQ) also showed significant changes post-intervention with medium to large effect sizes. Most importantly, changes in emotion regulation processes were linked to improved eating psychopathology. The qualitative analysis corroborated this finding, highlighting how the intervention helped them form new beliefs about emotions, which helped them reduce ED behaviours. Significant improvements in emotion processing and regulations, as well as psychopathology, along with positive qualitative feedback, suggest that the intervention effectively met its aims of increasing awareness of the link between emotions and eating psychopathology, providing help to identify and regulate emotions, and normalising emotional experiences. While our results are promising, further research is required to assess its effectiveness longer term and in clinical settings.

The buffet challenge: a behavioral assessment of eating behavior in adolescents with an eating disorder

ObjectiveEating disorders are characterized by disturbances in nutritional intake and abnormal mealtime behaviors. Laboratory eating paradigms offer a unique opportunity to accurately measure dietary intake and eating behaviors, however, these studies have predominantly occurred in adults. This paper describes the development and preliminary psychometric examination of the Buffet Challenge, a laboratory-based meal task for youths with an eating disorder.MethodWe recruited and assessed 56 participants as part of a randomized controlled trial of Family-Based Treatment for adolescents with anorexia nervosa. Adolescents completed the Buffet Challenge at baseline, midway through treatment (~ week 16 of a 6 months course), and end of treatment. Participants and their parents also reported eating disorder symptomatology and treatment related variables of interest were recorded.ResultsAll adolescents were willing to complete the Buffet Challenge at all time points, although one refused to give up their cellphone, and there were no significant adverse events recorded. Preliminary results are presented.ConclusionsOur initial pilot of this task in adolescents with anorexia nervosa demonstrates its acceptability, although investigation of our hypotheses was hindered by significant missing data due to COVID-related research shutdowns. Future studies should replicate procedures in a larger sample to ensure analyses are adequately powered.

Does embedding pediatric eating disorder treatment in primary care bridge the access gap?

ABSTRACT Given the numerous barriers to accessing child and adolescent eating disorder treatment, there is a need for innovation in how this care is delivered. Primary care-based eating disorder treatment has established proof-of-concept, yet it is unclear whether this model can bridge the treatment-access gap. This retrospective chart review study compared demographic and illness characteristics of 106 adolescents (M age = 15.1 years) SD = 1.8 consecutively evaluated in a primary care-based eating disorder clinic with 103 adolescent patients (M age = 15.2 years) SD = 2.2 seen consecutively in a specialty eating disorder clinic at the same medical center. Relative to adolescents in specialty care, those in the primary care group presented at a significantly higher BMI percentile, had less weight suppression, a shorter illness duration, lower rates of amenorrhea and lower scores on the EDE-Q Dietary Restraint subscale. In addition, more patients in the primary care group identified as non-white and had government/public assistance insurance compared to those in the specialty group. The results suggest that, compared to traditional specialty care clinics, embedded eating disorder treatment in primary care may reach a more racially and socioeconomically diverse group of adolescents when they are earlier in the course of their illness. Future research determining the relative effectiveness of this model as compared to interventions delivered in specialty care is needed.

Capacity to consent to treatment in severe eating disorders

Eating disorders represent a disabling, deadly and costly condition, whose principal treatment is constituted by weigh restoration and psychotherapy. Partial or total refuse of treatment is very common, leading some authors to question their decision-making capacity (DMC) to consent to treatment. However, very few studies have investigated treatment DMC, leading to contrasting results. Forty-five women were enrolled at the Psychiatric and Eating Disorders Unit of the University Hospital Policlinico Umberto I of Rome. Psychiatric symptoms severity (Brief Psychiatric Rating Scale Expanded, BPRS-E), treatment DMC (MacArthur Competence Assessment Tool for Treatment, MacCAT-T), depressive symptoms (Hamilton Depression Rating Scale, HAM-D), anxiety symptoms (Hamilton Anxiety Rating Scale, HAM-A), symptoms and psychological characteristics of eating disorders (Eating Disorder Inventory, EDI-3) and Metacognitive beliefs (Metacognitions Questionnaire 30, MCQ-30) were assessed. Sixty-seven percent of the total sample showed low treatment DMC; specifically, 70.4% of patients affected by Anorexia Nervosa, 72.7% of patients affected by Bulimia Nervosa, and 42.9% of patients affected by Binge Eating Disorder. Specific psychopathological symptoms enhance or hamper patients’ decisional capacities. Clinicians should be aware of the risk of impaired DMC in this vulnerable group of patients and pay attention at those factors suggesting the need of an in-depth evaluation.

The social epistemology of eating disorders: How our gaps in understanding challenge patient care.

In this article, I argue that various epistemic challenges associated with eating disorders (EDs) can negatively affect the care of already marginalized patient groups with various EDs. I will first outline deficiencies in our understanding of EDs-in research, healthcare settings, and beyond. I will then illustrate with examplescases where discriminatory misconceptions about what EDs are, the presentation and treatment of EDs, and who gets EDs, instantiate obstacles for the treatment of various ED patient groups.
