A multicenter audit of outpatient care for adult anorexia nervosa: Symptom trajectory, service use, and evidence in support of "early stage" versus "severe and enduring" classification

Is there a basis for a weight cut-off point? A large-scale investigation of atypical anorexia and anorexia nervosa subtypes among patients at a residential treatment centre

OBJECTIVE

There is debate surrounding how to differentiate between anorexia nervosa (AN) and atypical AN (atypAN) as diagnostic entities, and whether a distinction based on BMI is warranted. Better understanding eating disorder (ED) and emotional symptoms across atypAN and AN subtypes [AN-restricting (AN-R), AN-binge/purge (AN-BP)], with and without controlling for BMI, can elucidate how atypAN differs from AN subtypes and whether there is a basis for a BMI cut-off.

METHODS

1810 female patients at an ED treatment centre completed intake surveys. ANCOVAs assessed differences across AN-R (n = 853), AN-BP (n = 726), and atypAN (n = 231) groups on ED, depressive, and anxiety symptoms, anxiety sensitivity, experiential avoidance, and mindfulness, with and without controlling for BMI.

RESULTS

Relative to AN-R, atypAN and AN-BP groups endorsed significantly higher ED and depressive symptoms, anxiety sensitivity, experiential avoidance, and significantly lower mindfulness (all p < 0.001), but atypAN and AN-BP groups did not differ from one another. When controlling for BMI, all previously significant differences between atypAN and AN-R did not remain significant.

CONCLUSION

Individuals with atypAN who have a higher BMI experience more pronounced ED and emotional symptoms, suggesting that relying solely on BMI as a marker of illness severity may be problematic.

Efficacy and cost-effectiveness of a digital guided self-management intervention to support transition from intensive care to community care in anorexia nervosa (TRIANGLE): pragmatic multicentre randomised controlled trial and economic evaluation

Background

There is uncertainty regarding how best to support patients with anorexia nervosa following inpatient or day care treatment. This study evaluated the impact of augmenting intensive treatment with a digital, guided, self-management intervention (ECHOMANTRA) for patients with anorexia nervosa and their carers.

Methods

In this pragmatic multicentre randomised controlled trial and economic evaluation, patients with a diagnosis of anorexia nervosa or atypical anorexia nervosa, aged 16+ and attending one of the 31 inpatient or day-patient services in the UK were randomised with one of their carers to receive ECHOMANTRA plus treatment as usual (TAU), or TAU alone. ECHOMANTRA was hosted on a digital platform and included a workbook, recovery-oriented video-clips and online facilitated groups (patients only, carers only, joint patient-carer). Participants were randomised on a 1:1 ratio using a minimisation algorithm to stratify by site (N = 31) and severity (defined by BMI <15 and ≥ 15 kg/m2 at baseline). The primary outcome was patient depression, anxiety, and stress at 12 months. Primary and secondary outcomes were compared between trial arms on an intention-to-treat basis (ITT). This trial is registered with the ISRSTN registry, ISRCTN14644379.

Findings

Between July 01, 2017 and July 20, 2020, 371 patient-carer dyads were enrolled and randomly assigned to ECHOMANTRA + TAU (N = 185) or TAU alone (N = 186). There were no significant differences between trial arms with regards to the primary outcome (completed by N = 143 patients in the TAU group, Mean = 61.7, SD = 29.4 and N = 109 patients in the ECHOMANTRA + TAU group, Mean = 58.3, SD = 26.9; estimated mean difference 0.48 points; 95% CI -5.36 to 6.33; p = 0.87). Differences on secondary outcomes were small and non-significant (standardised effect size estimates ≤0.25). Five patients died (2 from suicide and 3 from physical complications) over the course of the trial, and this was unrelated to their participation in the study.

Interpretation

ECHOMANTRA added to TAU was not superior to TAU alone in reducing patient depression, anxiety, and stress symptoms. This may be explained by limited engagement with the intervention materials and changes in usual care practices since the beginning of the trial.

Yoga as an adjunct treatment for eating disorders: a qualitative enquiry of client perspectives

BACKGROUND

This qualitative enquiry explores the experiences and perspectives of individuals with an eating disorder (ED) regarding their perceptions of yoga as an adjunct intervention to psychotherapy. It also explores the feasibility, acceptability, and safety of yoga from their perspectives.

METHODS

This study used a practice-based evidence framework and employed semi-structured interviews with 16 females with an ED. Participants were asked about their perspectives on the use of yoga as an adjunct intervention in ED recovery, perceived risks and what factors supported or hindered engagement. Thematic template analysis was used.

RESULTS

Three topic areas were elaborated. The first included participants' perceptions of how yoga enhanced their ED recovery. The second included how and when participants came to find yoga in their ED recovery. The final topic explored factors that supported participants with ED to engage in yoga. These resulted in the development of guiding principles to consider when designing a yoga intervention for EDs.

CONCLUSIONS

This study adds further to the emerging evidence that yoga can bring complementary benefits to ED recovery and provides a biopsychosocial-spiritual framework for understanding these. Findings provide an understanding of how yoga programs can be adapted to improve safety and engagement for people with an ED. Yoga programs for people with EDs should be co-designed to ensure that the physical, social, and cultural environment is accessible and acceptable.

Characterising illness stages and recovery trajectories of eating disorders in young people via remote measurement technology (STORY): a multi-centre prospective cohort study protocol

BACKGROUND

Eating disorders (EDs) are serious, often chronic, conditions associated with pronounced morbidity, mortality, and dysfunction increasingly affecting young people worldwide. Illness progression, stages and recovery trajectories of EDs are still poorly characterised. The STORY study dynamically and longitudinally assesses young people with different EDs (restricting; bingeing/bulimic presentations) and illness durations (earlier; later stages) compared to healthy controls. Remote measurement technology (RMT) with active and passive sensing is used to advance understanding of the heterogeneity of earlier and more progressed clinical presentations and predictors of recovery or relapse.

METHODS

STORY follows 720 young people aged 16-25 with EDs and 120 healthy controls for 12 months. Online self-report questionnaires regularly assess ED symptoms, psychiatric comorbidities, quality of life, and socioeconomic environment. Additional ongoing monitoring using multi-parametric RMT via smartphones and wearable smart rings ('Ōura ring') unobtrusively measures individuals' daily behaviour and physiology (e.g., Bluetooth connections, sleep, autonomic arousal). A subgroup of participants completes additional in-person cognitive and neuroimaging assessments at study-baseline and after 12 months.

DISCUSSION

By leveraging these large-scale longitudinal data from participants across ED diagnoses and illness durations, the STORY study seeks to elucidate potential biopsychosocial predictors of outcome, their interplay with developmental and socioemotional changes, and barriers and facilitators of recovery. STORY holds the promise of providing actionable findings that can be translated into clinical practice by informing the development of both early intervention and personalised treatment that is tailored to illness stage and individual circumstances, ultimately disrupting the long-term burden of EDs on individuals and their families.

Staging models in eating disorders: A systematic scoping review of the literature

Eating Disorders (ED) are characterized by low remission rates, treatment drop-out, and residual symptoms. To improve assessment and treatment of ED, the staging approach has been proposed. This systematic scoping review is aimed at mapping the existing staging models that explicitly propose stages of the progression of ED. A systematic search of PubMed, PsycINFO, Scopus was conducted with the terms staging, anorexia nervosa, bulimia nervosa, binge-eating disorders, eating disorders. Eleven studies met inclusion criteria presenting nine ED staging models, mostly for anorexia nervosa. Three were empirically tested, one of which was through an objective measure specifically developed to differentiate between stages. Most staging models featured early stages in which the exacerbation of EDs unfolds and acute phases are followed by chronic stages. Intermediate stages were not limited to acute stages, but also residual phases, remission, relapse, and recovery. The criteria for stage differentiation encompassed behavioral, psychological, cognitive, and physical features including body mass index and illness duration. One study recommended stage-oriented interventions. The current review underscores the need to empirically test the available staging models and to develop and test new proposals of staging models for other ED populations. The inclusion of criteria based on medical features and biomarkers is recommended. Staging models can potentially guide assessment and interventions in daily clinical settings.

Inclusion of the severe and enduring anorexia nervosa phenotype in genetics research: a scoping review

BACKGROUND

Anorexia nervosa has one of the highest mortality rates of all mental illnesses. For those who survive, less than 70% fully recover, with many going on to develop a more severe and enduring phenotype. Research now suggests that genetics plays a role in the development and persistence of anorexia nervosa. Inclusion of participants with more severe and enduring illness in genetics studies of anorexia nervosa is critical.

OBJECTIVE

The primary goal of this review was to assess the inclusion of participants meeting the criteria for the severe enduring anorexia nervosa phenotype in genetics research by (1) identifying the most widely used defining criteria for severe enduring anorexia nervosa and (2) performing a review of the genetics literature to assess the inclusion of participants meeting the identified criteria.

METHODS

Searches of the genetics literature from 2012 to 2023 were performed in the PubMed, PsycINFO, and Web of Science databases. Publications were selected per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The criteria used to define the severe and enduring anorexia nervosa phenotype were derived by how often they were used in the literature since 2017. The publications identified through the literature search were then assessed for inclusion of participants meeting these criteria.

RESULTS

most prevalent criteria used to define severe enduring anorexia nervosa in the literature were an illness duration of ≥ 7 years, lack of positive response to at least two previous evidence-based treatments, a body mass index meeting the Diagnostic and Statistical Manual of Mental Disorders-5 for extreme anorexia nervosa, and an assessment of psychological and/or behavioral severity indicating a significant impact on quality of life. There was a lack of consistent identification and inclusion of those meeting the criteria for severe enduring anorexia nervosa in the genetics literature.

DISCUSSION

This lack of consistent identification and inclusion of patients with severe enduring anorexia nervosa in genetics research has the potential to hamper the isolation of risk loci and the development of new, more effective treatment options for patients with anorexia nervosa.

Severe enduring anorexia nervosa (SE-AN) treatment options and their effectiveness: a review of literature

INTRODUCTION

 For nearly 20% of patients diagnosed with Anorexia Nervosa (AN), the eating disorder (ED) is prolonged and becomes long-lasting. It has been reported that patients diagnosed with Severe Enduring Anorexia Nervosa (SE-AN) have worse ED symptoms, higher rates of lifetime hospitalization, and lower psychosocial well-being compared to patients with shorter disease duration.

OBJECTIVES

 This review aims to describe the treatments proposed to date and their effectiveness on SE-AN-related outcomes.

METHODS

 We conducted a PubMed search for studies addressing the issue of treatment approach to SE-AN adults, that were published between 2003 and 2023, peer-reviewed, written in the English language, and available in full-text. Next, we inductively created relevant macro-themes by synthesizing the data from the included articles.

RESULTS

 Of 251 PubMed studies, 25 articles were considered for data extraction, all published between 2003 and 2022. We identified three macro-themes. The first macro-theme, "Psychotherapy", mostly takes into consideration treatment effectiveness of cognitive behavioral therapy (CBT). Various reports determined its greater effectiveness compared to Specialist Supportive Clinical Management (SSCM), and one study proved that outpatient CBT is a valid alternative to hospitalization. The second one involves "Pharmacological Treatments". Research on dronabinol, a synthetic orexigenic cannabinoid, antipsychotics (in particular, olanzapine and haloperidol), and ketamine showed some mixed results regarding the often-complementary areas of weight gain and improvement in ED-related symptoms. Regarding the third macro-theme, "Brain Stimulation Therapies," such as Repetitive Transcranial Magnetic Stimulation (rTMS) and Deep Brain Stimulation (DBS), we found promising results in improving ED-related psychological traits (such as mood and anxiety), affective regulation, and quality of life. However, we have observed divergent results regarding outcome measures such as BMI and weight gain.

CONCLUSIONS

 SE-AN patients are predicted to encounter both medical complications and psychological distress of increasing severity that will inevitably affect their quality of life; to our knowledge, research evidence on treatment options for SE-AN remains limited, and the methodological quality of studies is generally low. These findings denote the need to focus future research efforts on effective treatment strategies specific to long-lasting EDs.

Associations between disordered eating, internalizing symptoms, and behavioral and neural correlates of response inhibition in preadolescence

Response inhibition difficulties are reported in individuals with eating disorders (EDs), anxiety, and depression. Although ED symptoms and internalizing symptoms co-occur in preadolescence, there is limited research examining associations between these symptoms and response inhibition in this age group. This study is the first to investigate the associations between behavioral and neural markers of response inhibition, disordered eating (DE), and internalizing symptoms in a community sample of preadolescents. Forty-eight children (M age = 10.95 years, 56.3% male) completed a Go/NoGo task, whereas electroencephalography was recorded. Self-report measures of DE and internalizing symptoms were collected. Higher levels of anxiety and depression were associated with neural markers of suboptimal response inhibition (attenuated P3NoGo amplitudes) in preadolescence. In contrast, higher levels of depression were associated with greater response inhibition at a behavioral level. These findings suggest internalizing symptoms in preadolescence are associated with P3-indexed difficulties in evaluation and monitoring, but these are not sufficient to disrupt behavioral performance on a response inhibition task. This pattern may reflect engagement of compensatory processes to support task performance. DE was not significantly associated with response inhibition, suggesting that difficulties in response inhibition may only be reliably observed in more chronic and severe DE and ED presentations.

Acceptability of Specialist Psychotherapy with Emotion for Anorexia in Kent and Sussex (SPEAKS): A novel intervention for anorexia nervosa

OBJECTIVE

Investigate the acceptability of Specialist Psychotherapy with Emotion for Anorexia in Kent and Sussex (SPEAKS), a novel intervention for anorexia nervosa (AN), conducted as a feasibility trial to provide an initial test of the intervention.

METHODS

SPEAKS therapy lasting 9-12 months was provided to 34 people with AN or atypical AN by eight specialist eating disorder therapists trained in the model across two NHS Trusts in the UK (Kent and Sussex) during a feasibility trial. All participants were offered a post-therapy interview; sixteen patients and six therapists agreed. All patient participants were adult females. Interviews were semi-structured and asked questions around individuals' experience of SPEAKS, the acceptability of the intervention and of the research methods. Interviews were analyzed using thematic analysis.

RESULTS

Key areas explored in line with research questions led to 5 overarching themes and 14 subthemes: (1) shift in treatment focus and experience, (2) balancing resources and treatment outcomes, (3) navigating the online treatment environment, (4) therapist adaptation and professional development, and (5) research processes.

DISCUSSION

SPEAKS was found to be an acceptable intervention for treating AN from the perspective of patients and therapists. The findings provide strong support for delivery of a larger scale randomized control trial. Recommendations for future improvements, particularly pertaining to therapist understanding of the treatment model are detailed, alongside broader clinical implications.

PUBLIC SIGNIFICANCE

We aimed to evaluate the acceptability of a new anorexia nervosa treatment called SPEAKS. Interviews were conducted with patients and therapists involved in the pilot study and responses were analyzed. Results showed that both patients and therapists found SPEAKS to be an acceptable treatment for anorexia nervosa. The study suggests that SPEAKS meets the criteria for moving forward with a larger trial to assess its effectiveness.

Outcomes in people with eating disorders: a transdiagnostic and disorder-specific systematic review, meta-analysis and multivariable meta-regression analysis

Eating disorders (EDs) are known to be associated with high mortality and often chronic and severe course, but a recent comprehensive systematic review of their outcomes is currently missing. In the present systematic review and meta-analysis, we examined cohort studies and clinical trials published between 1980 and 2021 that reported, for DSM/ICD-defined EDs, overall ED outcomes (i.e., recovery, improvement and relapse, all-cause and ED-related hospitalization, and chronicity); the same outcomes related to purging, binge eating and body weight status; as well as mortality. We included 415 studies (N=88,372, mean age: 25.7±6.9 years, females: 72.4%, mean follow-up: 38.3±76.5 months), conducted in persons with anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), other specified feeding and eating disorders (OSFED), and/or mixed EDs, from all continents except Africa. In all EDs pooled together, overall recovery occurred in 46% of patients (95% CI: 44-49, n=283, mean follow-up: 44.9±62.8 months, no significant ED-group difference). The recovery rate was 42% at <2 years, 43% at 2 to <4 years, 54% at 4 to <6 years, 59% at 6 to <8 years, 64% at 8 to <10 years, and 67% at ≥10 years. Overall chronicity occurred in 25% of patients (95% CI: 23-29, n=170, mean follow-up: 59.3±71.2 months, no significant ED-group difference). The chronicity rate was 33% at <2 years, 40% at 2 to <4 years, 23% at 4 to <6 years, 25% at 6 to <8 years, 12% at 8 to <10 years, and 18% at ≥10 years. Mortality occurred in 0.4% of patients (95% CI: 0.2-0.7, n=214, mean follow-up: 72.2±117.7 months, no significant ED-group difference). Considering observational studies, the mortality rate was 5.2 deaths/1,000 person-years (95% CI: 4.4-6.1, n=167, mean follow-up: 88.7±120.5 months; significant difference among EDs: p<0.01, range: from 8.2 for mixed ED to 3.4 for BN). Hospitalization occurred in 26% of patients (95% CI: 18-36, n=18, mean follow-up: 43.2±41.6 months; significant difference among EDs: p<0.001, range: from 32% for AN to 4% for BN). Regarding diagnostic migration, 8% of patients with AN migrated to BN and 16% to OSFED; 2% of patients with BN migrated to AN, 5% to BED, and 19% to OSFED; 9% of patients with BED migrated to BN and 19% to OSFED; 7% of patients with OSFED migrated to AN and 10% to BN. Children/adolescents had more favorable outcomes across and within EDs than adults. Self-injurious behaviors were associated with lower recovery rates in pooled EDs. A higher socio-demographic index moderated lower recovery and higher chronicity in AN across countries. Specific treatments associated with higher recovery rates were family-based therapy, cognitive-behavioral therapy (CBT), psychodynamic therapy, and nutritional interventions for AN; self-help, CBT, dialectical behavioral therapy (DBT), psychodynamic therapy, nutritional and pharmacological treatments for BN; CBT, nutritional and pharmacological interventions, and DBT for BED; and CBT and psychodynamic therapy for OSFED. In AN, pharmacological treatment was associated with lower recovery, and waiting list with higher mortality. These results should inform future research, clinical practice and health service organization for persons with EDs.

EDIFY (Eating Disorders: Delineating Illness and Recovery Trajectories to Inform Personalised Prevention and Early Intervention in Young People): project outline

EDIFY (Eating Disorders: Delineating Illness and Recovery Trajectories to Inform Personalised Prevention and Early Intervention in Young People) is an ambitious research project aiming to revolutionise how eating disorders are perceived, prevented and treated. Six integrated workstreams will address key questions, including: What are young people's experiences of eating disorders and recovery? What are the unique and shared risk factors in different groups? What helps or hinders recovery? How do the brain and behaviour change from early- to later-stage illness? How can we intervene earlier, quicker and in a more personalised way? This 4-year project, involving over 1000 participants, integrates arts, design and humanities with advanced neurobiological, psychosocial and bioinformatics approaches. Young people with lived experience of eating disorders are at the heart of EDIFY, serving as advisors and co-producers throughout. Ultimately, this work will expand public and professional perceptions of eating disorders, uplift under-represented voices and stimulate much-needed advances in policy and practice.

Severe-Enduring Anorexia Nervosa (SE-AN): a case series

BACKGROUND

Anorexia Nervosa (AN) poses significant therapeutic challenges, especially in cases meeting the criteria for Severe and Enduring Anorexia Nervosa (SE-AN). This subset of AN is associated with severe medical complications, frequent use of services, and the highest mortality rate among psychiatric disorders.

CASE PRESENTATION

In the present case series, 14 patients were selected from those currently or previously taken care of at the Eating Disorders Outpatients Unit of the Maggiore Hospital in Bologna between January 2012 and May 2023. This case series focuses on the effects of the disease, the treatment compliance, and the description of those variables that could help understand the great complexity of the disorder.

CONCLUSION

This case series highlights the relevant issue of resistance to treatment, as well as medical and psychological complications that mark the life course of SE-AN patients. The chronicity of these disorders is determined by the overlapping of the disorder's ego-syntonic nature, the health system's difficulty in recognizing the problem in its early stages, and the presence of occupational and social impairment.

Body composition assessment in adult females with anorexia nervosa and bulimia nervosa - a cross-sectional study comparing dual-energy X-ray absorptiometry scan and isotopic dilution of deuterium

BACKGROUND

Eating disorders (EDs) compromise individuals' nutritional status, affecting among other organs and systems, bone health.

OBJECTIVE

This study aimed to assess and compare bone mineral density (BMD) from dual-energy x-ray absorptiometry (DXA) scan and deuterium (D₂O) dilution of adult females with anorexia nervosa (AN) and bulimia nervosa (BN).

METHODS

This was a cross-sectional study with 53 female participants (18-49 years) with a diagnosis of AN (N = 25) or BN (N = 28). DXA scan was performed to assess BMD, fat mass, and fat-free mass, and D₂O dilution was used to assess total body water (TBW), fat mass, and fat-free mass. Interviews/questionnaires were used to assess symptoms, illness trajectory, and physical activity. T-test, Chi-squared test, Pearson's linear correlation, linear regressions, and Bland-Altman analyses were performed, with a significance level of 5%.

RESULTS

TBW below the recommended level for adult females (≥ 45%) was more frequent in BN (60%) compared with AN (21%; P = 0.013). FMI (soft tissue only) (t-test P = 0.06), and FFMI (t-test P = 0.08) agreed between DXA scan and D₂O dilution. Only FFMI did not show systematic bias of proportion (β:-0.2, P = 0.177). The diagnosis of BN, binge-eating episodes, and physical activity in AN were associated with the differences in the methods' results. FMI was positively associated with BMD in AN, and both FMI and FFMI were positively associated with BMD in BN.

CONCLUSION

In adult females with EDs, DXA scan and D₂O dilution achieved agreement for FMI and FFMI. Changes in fat mass and fat-free mass are important in understanding the mechanisms behind bone loss in EDs. Protocols for body composition assessment in EDs can help to minimize the effect of the ED diagnosis, ED behaviors (i.e., excessive exercise and purging behaviors) and weight on the accuracy of measurements.

Novel ketamine and zinc treatment for anorexia nervosa and the potential beneficial interactions with the gut microbiome

Anorexia nervosa (AN) is a severe illness with diverse aetiological and maintaining contributors including neurobiological, metabolic, psychological, and social determining factors. In addition to nutritional recovery, multiple psychological and pharmacological therapies and brain-based stimulations have been explored; however, existing treatments have limited efficacy. This paper outlines a neurobiological model of glutamatergic and γ-aminobutyric acid (GABA)-ergic dysfunction, exacerbated by chronic gut microbiome dysbiosis and zinc depletion at a brain and gut level. The gut microbiome is established early in development, and early exposure to stress and adversity contribute to gut microbial disturbance in AN, early dysregulation to glutamatergic and GABAergic networks, interoceptive impairment, and inhibited caloric harvest from food (e.g., zinc malabsorption, competition for zinc ions between gut bacteria and host). Zinc is a key part of glutamatergic and GABAergic networks, and also affects leptin and gut microbial function; systems dysregulated in AN. Low doses of ketamine in conjunction with zinc, could provide an efficacious combination to act on NMDA receptors and normalise glutamatergic, GABAergic and gut function in AN.

A framework for conceptualising early intervention for eating disorders

OBJECTIVE

This paper outlines the evidence base for early intervention for eating disorders; provides a global overview of how early intervention for eating disorders is provided in different regions and settings; and proposes policy, service, clinician and research recommendations to progress early intervention for eating disorders.

METHOD AND RESULTS

Currently, access to eating disorder treatment often takes many years or does not occur at all. This is despite neurobiological, clinical and socioeconomic evidence showing that early intervention may improve outcomes and facilitate full sustained recovery from an eating disorder. There is also considerable variation worldwide in how eating disorder care is provided, with marked inequalities in treatment provision. Despite these barriers, there are existing evidence-based approaches to early intervention for eating disorders and progress is being made in scaling these.

CONCLUSIONS

We propose action steps for the field that will transform eating disorder service provision and facilitate early detection, treatment and recovery for everyone affected by eating disorders, regardless of age, socioeconomic status and personal characteristics.

Patients' perspectives on screening for disordered eating among adolescents with type 1 diabetes

PURPOSE

People with type 1 diabetes have an increased risk of disordered eating (DE) and eating disorders (ED). Screening is recommended however little is known about patients' perspectives on screening questionnaires. This paper reports qualitative analyses of patients' perspectives on the questionnaire Diabetes Eating Problem Survey Revised (DEPS-R), including acceptability, attitudes, and cognitive understanding.

RESEARCH DESIGN AND METHODS

15 adolescents with type 1 diabetes between 11 and 18 years, were interviewed. A semi-structured format and a qualitative Interpretive Descriptive (ID) methodology was chosen.

RESULTS

The analyses identified four themes: (1) The Questionnaire, (2) Reframing Diabetes Visits, (3) This is (not) for me, and (4) Out in the Open. The DEPS-R was completed with-in 5-10 min. with no technical difficulties. The questionnaire altered the diabetes visit for some, creating a new dialog, and time for self-reflection. Adolescents appreciated the direct approach in the questionnaire, and showed willingness to complete the questionnaire, when presented to them by a health care professional (HCP). One item in the DEPS-R proved difficult to understand for some participants.

CONCLUSION

The study highlights DEPS-R as a clinically relevant screening questionnaire. Completing DEPS-R prior to a consultation opens the door to a consultation that invites the adolescent to address matters of eating behavior. Our findings suggest that systematic screening of DE/ED using the DEPS-R is both accepted and welcomed by adolescents with type 1 diabetes. Future research should focus on a potential update of selected items in DEPS-R.

National roll-out of early intervention for eating disorders: Process and clinical outcomes from first episode rapid early intervention for eating disorders

AIM

First Episode Rapid Early Intervention for Eating Disorders (FREED) is an early intervention model for young people with recent-onset eating disorders (ED). Promising results from a previous single-centre study and a four-centre study (FREED-Up) have led to the rapid national scaling of FREED to ED services in England (FREED-4-All). Our aim was to evaluate duration of an untreated ED (DUED), wait time target adherence, and clinical outcomes in FREED-4-All and compare these to the (benchmark) findings of the earlier FREED-Up study.

METHOD

FREED services submit de-identified data to the central FREED team quarterly. The current study covers the period between September 2018 and September 2021. This FREED-4-All dataset includes 2473 patients. These were compared to 278 patients from the FREED-Up study.

RESULTS

DUED was substantially shorter in the FREED-4-All dataset relative to the FREED-Up study (15 vs. 18 months). Adherence to the wait time targets was comparable in both cohorts (~85% of engagement calls attempted in <2 days, ~50%-60% of assessments offered in <14 days, ~40% of treatment offered in <28 days). Patients in the FREED-4-All dataset experienced significant improvements in ED and general psychological symptoms from pre- to post-treatment that were comparable to the FREED-Up study. These findings should be interpreted cautiously as only 6% of FREED-4-All patients had post-treatment data.

CONCLUSIONS

Data from the FREED-4-All evaluation suggest that FREED is replicating at scale. However, these data are flawed, uncertain, proximate, and sparse and should therefore be used carefully alongside other evidence and clinical experience to inform decision making.

A network analysis in adolescent anorexia nervosa exploring the connection between both patient and carer reactions and outcome

OBJECTIVE

This paper used network analysis to test the associations between eating disorder-related psychopathology and carers' responses to anorexia nervosa symptoms in adolescents. Additionally, the prognostic value of central and bridge network nodes was explored.

METHOD

This is a secondary analysis of a three-armed randomised-controlled-trial of adolescents with anorexia nervosa (n = 149) and their primary carer (n = 149) who were allocated to either treatment as usual (TAU), or one of two versions of a carer skills intervention (ECHO) added to TAU. A network analysis was run in the full sample. The prognostic role of central and bridge nodes was tested through multiple regression analyses.

RESULTS

Carers' depression and emotional over-involvement, as well as patients' depression showed the highest strength centrality. Patients' depression and carers' accommodation exhibited the highest bridge expected influence. Across the full sample, and in the ECHO group, carers' accommodation predicted patients' higher body mass index (BMI), while patients' depression predicted worse psychosocial functioning at 1-year follow-up. In the ECHO group, higher carers' depression also predicted lower BMI.

CONCLUSIONS

Carers' accommodation and depression in both carers and patients were involved in the maintenance of psychopathology in adolescents with anorexia nervosa. Depression in both patients and carers is a potential treatment target for family interventions.

Creating a care pathway for patients with longstanding, complex eating disorders

BACKGROUND

Recovery rates for people with eating disorders are low; fewer than half recover and approximately 20% develop a longstanding eating disorder. Patients with longstanding eating disorders are often referred to as "SEED" (severe and enduing eating disorders) although this remains controversial and is not acknowledged in the British treatment guidance. This project aimed to generate recommendations for a longstanding eating disorder care pathway by identifying what proportion of patients have longstanding eating disorders and how to best identify and support them.

METHODS

Initially, a literature review was completed, followed by interviews with service-users who consider themselves to have longstanding eating disorders, and focus groups with staff members. The results were combined to create a definition of a longstanding eating disorder which was used to establish how many service-users could benefit from the pathway. The qualitative data was used to produce recommendations for a tailored pathway for those with longstanding eating disorders.

RESULTS

The results highlighted that, although "SEED" is often used, participants preferred to be referred to as "longstanding" or having no label. Qualitative analysis identified four themes in relation to supporting this population group which described how to structure the service and individualise care, as well as patients' relationship to the service, and how to build a life after eating disorder services.

CONCLUSIONS

Recommendations included promoting a hopeful message, focusing on quality of life and introducing peer support. Crucially, accessing the pathway should not result in being labelled "SEED", nor should it prevent access to recovery focused interventions including weight restoration. The full list of recommendations are included as well as the implications of the project and limitations.

A Delphi study to explore clinician and lived experience perspectives on setting priorities in eating disorder services

Background

Due to scarce resources and high demand, priority setting in mental health services is necessary and inevitable. To date, no study has examined priority setting in eating disorder (ED) services specifically. Here, we evaluate the level of consensus and perceived relative importance of factors used to determine patient prioritisation in ED services, amongst clinicians and individuals with lived experience (LE) of an ED.

Methods

A three round Delphi study and a ranking task were used to determine the level of consensus and importance. Consensus was defined as > 80% agreement or disagreement. Items that reached consensus for agreement were ranked in order of importance from most to least important. Participants were 50 ED clinicians and 60 LE individuals. Participant retention across rounds 2, 3, and 4 were 92%, 85%, and 79%, respectively.

Results

Over three iterative rounds, a total of 87 statements about patient prioritisation were rated on a 5-point Likert-scale of agreement. Twenty-three items reached consensus in the clinician panel and 20 items reached consensus in the LE panel. The pattern of responding was broadly similar across the panels. The three most important items in both panels were medical risk, overall severity, and physical health deteriorating quickly. Clinicians tended to place greater emphasis on physical risk and early intervention whereas the LE panel focused more on mental health and quality of life.

Conclusions

Eating disorder services tend to prioritise patients based upon medical risk and severity, and then by the order in which patients are referred. Our findings align in some respects with what is observed in services, but diverge in others (e.g., prioritising on quality of life), providing important novel insights into clinician and LE opinions on waiting list prioritisation in EDs. More research is warranted to validate these findings using multi-criterion decision techniques and observational methods. We hope these findings provide a foundation for future research and encourage evidence-based conversations around priority setting in ED services.

Prevalence of High-Risk Disordered Eating Amongst Adolescents and Young Adults in the Middle East: A Scoping Review

High-risk disordered eating (HRDE) negatively affects physical, mental, and social wellbeing. This scoping review aimed to estimate the prevalence of HRDE amongst adolescents and young adults in the Middle East. MEDLINE database was searched for studies published in English or Arabic from 1 January 2000 to 30 September 2020, estimating HRDE prevalence (using the Eating Attitudes Test 26 or 40 item questionnaire) in the Middle East. Two reviewers independently screened abstracts and full texts of potentially eligible records, followed by data extraction from eligible studies. Nineteen studies (n = 16,288; 65.8% female) from Egypt, Iran, Israel, Jordan, Kuwait, Libya, Oman, Palestine, Saudi Arabia, Syria, Turkey, and the United Arab Emirates were included. Prevalence of HRDE varied considerably across countries and was lowest amongst adolescents in Israel (F 8.2%; M 2.8%) and highest amongst university students in Egypt (F 75.8%; M 69.6%). Prevalence of high-risk for anorexia nervosa ranged from 0.0% in Jordan to 9.5% in Oman; high-risk for bulimia nervosa from 0.6% in Jordan to 1.0% in the United Arab Emirates; and high-risk for binge eating disorder was 1.0% and 1.8% in Turkey and Jordan, respectively. Future studies should employ a standardized two-stage design with clinical diagnosis to verify the prevalence of abnormal eating behaviours in the Middle East.

Severe and Enduring' Stage in Anorexia Nervosa: Comparing Eating Attitudes, Impairment and Associated Psychopathology

This study aimed to assess differences in eating attitudes, impairment, and related psychopathology at treatment presentation for patients with "Non-severe and enduring Anorexia Nervosa" (illness duration of <7 years) and patients with "severe and enduring Anorexia Nervosa" (illness duration of 7 years or more). One hundred and thirty-nine patients diagnosed with Anorexia Nervosa participated in this study. Participants were interviewed with the Eating Disorder Examination (EDE) and asked to complete several questionnaires at the end of the first treatment appointment. We also explored differences at treatment presentation by considering alternative criteria to define groups, namely a composite of illness duration and clinical impairment (≥16 CIA total score). No differences were found when comparing participants based on illness duration. However, when participants were classified into a different classification scheme: "Non-severe and enduring Anorexia Nervosa" (illness duration <7 years and a CIA total score <16) vs. "severe and enduring Anorexia Nervosa" (illness duration ≥7 years and CIA total score ≥16), significant differences were found in terms of eating pathology, depressive symptomatology, psychological distress, and emotion dysregulation. Further research is needed to better understand the role of illness duration and clinical impairment in informing the course of AN.

Early detection of eating disorders: a scoping review

PURPOSE

Early detection of eating disorders (EDs) could improve their prognosis, decrease morbidity and mortality, and prevent the risk of evolution towards a chronic form and somatic, psychiatric and psychosocial complications. The objective of this review was to examine the current scientific data concerning the early detection of EDs, which is one of the facets of secondary prevention.

METHOD

A scoping literature review was carried out following the PRISMA-ScR criteria, including all articles on ED detection published up to 2021 on PUBMED and PSYCINFO.

RESULTS

43 articles were included. Anorexia nervosa and bulimia nervosa were the most widely studied disorders. The articles focused on professionals from the medical field (GPs, psychiatrists, gynaecologists, gastroenterologists and residents), from the paramedical field, from education and sport, and from the general population. The assessments conducted with the professionals receiving interventions aiming to improve detection demonstrated their efficacy. Interventions for ED detection in the general population and at school seemed less efficacious.

CONCLUSION

The results highlighted some lines of action to be implemented. They pointed towards improving initial and continuing education for professional carers; e-learning could be an interesting solution for continuing education. Improving training with specific instructors, school personnel and sports professionals is also one of the solutions for a better detection of EDs. Specific recommendations could be published for fitness centre professionals to help them to deal with clients suspected of having an ED. Among secondary school students and in the general population, a better dissemination of mental health literacy and the development of mental health first aid programs could help improve early detection.

The Rise and Fall of Dopamine: A Two-Stage Model of the Development and Entrenchment of Anorexia Nervosa

Dopamine has long been implicated as a critical neural substrate mediating anorexia nervosa (AN). Despite nearly 50 years of research, the putative direction of change in dopamine function remains unclear and no consensus on the mechanistic role of dopamine in AN has been achieved. We hypothesize two stages in AN- corresponding to initial development and entrenchment- characterized by opposite changes in dopamine. First, caloric restriction, particularly when combined with exercise, triggers an escalating spiral of increasing dopamine that facilitates the behavioral plasticity necessary to establish and reinforce weight-loss behaviors. Second, chronic self-starvation reverses this escalation to reduce or impair dopamine which, in turn, confers behavioral inflexibility and entrenchment of now established AN behaviors. This pattern of enhanced, followed by impaired dopamine might be a common path to many behavioral disorders characterized by reinforcement learning and subsequent behavioral inflexibility. If correct, our hypothesis has significant clinical and research implications for AN and other disorders, such as addiction and obesity.

The First Episode Rapid Early Intervention for Eating Disorders - Upscaled study: Clinical outcomes

BACKGROUND

First Episode Rapid Early Intervention for Eating Disorders (FREED) is a service model and care pathway for emerging adults aged 16 to 25-years with a recent onset eating disorder (ED) of <3 years. A previous single-site study suggests that FREED significantly improves clinical outcomes compared to treatment-as-usual (TAU). The present study (FREED-Up) assessed the scalability of FREED. A multi-centre quasi-experimental pre-post design was used, comparing patient outcomes before and after implementation of FREED in participating services.

METHODS

FREED patients (n = 278) were consecutive, prospectively ascertained referrals to four specialist ED services in England, assessed at four time points over 12 months on ED symptoms, mood, service utilization and cost. FREED patients were compared to a TAU cohort (n = 224) of similar patients, identified retrospectively from electronic patient records in participating services. All were emerging adults aged 16-25 experiencing a first episode ED of <3 years duration.

RESULTS

Overall, FREED patients made significant and rapid clinical improvements over time. 53.2% of FREED patients with anorexia nervosa reached a healthy weight at the 12-month timepoint, compared to only 17.9% of TAU patients (X² [1, N = 107] = 10.46, p < .001). Significantly fewer FREED patients required intensive (i.e., in-patient or day-patient) treatment (6.6%) compared to TAU patients (12.4%) across the follow-up period (X² [1, N = 40] = 4.36, p = .037). This contributed to a trend in cost savings in FREED compared to TAU (-£4472, p = .06, CI -£9168, £233).

DISCUSSION

FREED is robust and scalable and is associated with substantial improvements in clinical outcomes, reduction in inpatient or day-patient admissions, and cost-savings.

Clinical factors predicting impaired executive functions in eating disorders: The role of illness duration

Poor performance in executive functions is observed in individuals with eating disorders (EDs). These impairments have usually been associated with the presence of comorbid psychopathology or with higher severity of EDs. However, few studies have explored the interaction between illness duration and deficits in executive functions. The present study investigates the association between ED duration and performance in decision-making, inhibitory control, and cognitive flexibility in the anorexia nervosa restrictive subtype (AN-R), bulimic/purging subtype (AN-BP), and binge spectrum disorders (BSDs) (namely, bulimia nervosa and binge eating disorder) among 116 women with EDs compared with 123 women healthy controls (HCs). Using cumulative survival analysis, we estimated the risk of deficits related to illness duration. Predictors of executive dysfunctions were assessed by regression analysis, including as potential predictors illness duration, severity of general psychopathology, and ED symptomatology. Results showed poor decision-making and cognitive flexibility in participants with EDs compared with HCs. ED duration was associated with poor inhibitory control in the AN-BP group and poor cognitive flexibility in the BSD group. The illness duration increased the risk of presenting early deficits in executive function. In decision-making and inhibitory control, the AN-R group showed the earliest deficits, whereas in cognitive flexibility it was the BSD group. ED duration predicted impaired cognitive flexibility in the BSD group and impaired inhibitory control in the AN-BP group, whereas the severity of general psychopathological symptoms was a predictor of impaired cognitive flexibility in individuals with AN-R. These results highlight the relevance of illness duration in executive dysfunctions in EDs.

The development and psychometric evaluation of FABIANA-checklist: a scale to assess factors influencing treatment initiation in anorexia nervosa

BACKGROUND

A long duration of untreated illness (DUI) is an unfavorable prognostic factor in anorexia nervosa (AN) and is associated with chronic illness progression. Although previous preventive measures aimed at reducing DUI and thus improving short- and long-term treatment outcomes have been partially successful, a better understanding of the factors involved in the sensitive phase prior to treatment initiation is needed. To date, there is no validated instrument available to assess these factors specifically for patients with AN. The FABIANA-project (Facilitators and barriers in anorexia nervosa treatment initiation) aims at identifying predictors of the DUI in order to target preventive measures better in the future. As part of this project, the FABIANA-checklist was developed, based on a multi-informant perspective and a multimodal bottom-up approach. The present study focusses on the process of item generation, item selection and psychometric validation of the checklist.

METHODS

Based upon a previous qualitative study, an initial set of 73 items was generated for the most frequently mentioned facilitators and barriers of treatment initiation in AN. After a process of consensual rating and cognitive pre-testing, the resulting 25-item version of the FABIANA-checklist was provided to a sample of female patients (N = 75), aged ≥ 14 years with AN that underwent their first psychotherapeutic treatment in the last 12 months. After item analysis, dimensionality of the final version of the FABIANA-checklist was tested by Principal Component Analysis (PCA). We evaluated construct validity assuming correlations with related constructs, such as perceived social support (F-SozU), support in the health care system (PACIC-5A), illness perception and coping (BIPQ).

RESULTS

We included 54 adult and 21 adolescent patients with AN, aged on average 21.4 years. Average BMI was 15.5 kg/m², age of onset was 19.2 years and average DUI was 2.25 years. After item analysis, 7 items were excluded. The PCA of the 18-item-FABIANA-checklist yielded six components explaining 62.64% of the total variance. Overall internal consistency was acceptable (Cronbach's α = .76) and construct validity was satisfactory for 14 out of 18 items. Two consistent components emerged: "primary care perceived as supportive and competent" (23.33%) and "emotional and practical support from relatives" (9.98%). With regard to the other components, the heterogeneity of the items led to unsatisfactory internal consistency, single item loading and in part ambiguous interpretability.

CONCLUSIONS

The FABIANA-checklist is a valid instrument to assess factors involved in the process of treatment initiation of patients with AN. Psychometrics and dimensionality testing suggests that experienced emotional and practical support from the primary health care system and close relatives are main components. The results indicate that a differentiated assessment at item level is appropriate. In order to quantify the relative importance of the factors and to derive recommendations on early-intervention approaches, the predictive effect of the FABIANA-items on the DUI will be determined in a subsequent study which will further include the perspective of relatives and primary caregivers.

Network intervention analysis to assess the trajectory of change and treatment effects associated with the use of online guided self-help for anorexia nervosa

AIM

The aim of this study was to use the innovative technique of Network Intervention Analysis (NIA) to examine the trajectory of symptom change associated with the use of a digital guided self-help intervention (RecoveryMANTRA) to augment treatment as usual in adult anorexia nervosa.

METHODS

Self-reported eating disorder symptoms and mood (stress, anxiety and depression), work and social adjustment, motivation and treatment (Treatment as usual + RecoveryMANTRAand Treatment as usual) were included as nodes in the network and examined using NIA. Networks were computed at baseline (n = 88, 99), at end of treatment (6 weeks, n = 71, 75) and at 6- (n = 58, 63) and 12-month (n = 52, 63) follow-up.

RESULTS

RecoveryMANTRA was associated with a direct effect on anxiety, shape concern and restraint at the end of the intervention. This effect was not maintained at follow-up. There were no direct effects of RecoveryMANTRA on motivation, stress and depression.

CONCLUSIONS

These findings indicate that RecoveryMANTRA exerts a direct effect on eating disorder symptoms and anxiety. NIA is a promising method to evaluate trajectories of clinical change and direct and indirect effects of a therapeutic intervention compared to a control condition.

Early weight gain trajectories in first episode anorexia: predictors of outcome for emerging adults in outpatient treatment

BACKGROUND

Early response to treatment has been shown to be a predictor of later clinical outcomes in eating disorders (EDs). Specifically, early weight gain trajectories in anorexia nervosa (AN) have been shown to predict higher rates of later remission in inpatient treatment. However, no study has, as of yet, examined this phenomenon within outpatient treatment of first episode cases of AN or in emerging adults.

METHODS

One hundred seven patients with AN, all between the ages of 16 and 25 and with an illness duration of < 3 years, received treatment via the first episode rapid early intervention in eating disorders (FREED) service pathway. Weight was recorded routinely across early treatment sessions and recovery outcomes (BMI > 18.5 kg/m2 and eating psychopathology) were assessed up to 1 year later. Early weight gain across the first 12 treatment sessions was investigated using latent growth mixture modelling to determine distinct classes of change. Follow-up clinical outcomes and remission rates were compared between classes, and individual and clinical characteristics at baseline (treatment start) were tested as potential predictors.

RESULTS

Four classes of early treatment trajectory were identified. Three of these classes (n = 95), though differing in their early change trajectories, showed substantial improvement in clinical outcomes at final follow-up. One smaller class (n = 12), characterised by a 'higher' start BMI (> 17) and no early weight gain, showed negligible improvement 1 year later. Of the three treatment responding groups, levels of purging, depression, and patient reported carer expressed emotion (in the form of high expectations and low tolerance of the patient) determined class membership, although these findings were not significant after correcting for multiple testing. A higher BMI at treatment start was not sufficient to predict optimal clinical outcomes.

CONCLUSION

First episode cases of AN treated via FREED fit into four distinct early response trajectory classes. These may represent subtypes of first episode AN patients. Three of these four trajectories included patients with substantial improvements 1 year later. For those in the non-response trajectory class, treatment adjustments or augmentations could be considered earlier, i.e., at treatment session 12.

How and why does the disease progress? A qualitative investigation of the transition into long-standing anorexia nervosa

OBJECTIVE

Despite an increased interest in understanding characteristics of long-standing anorexia nervosa (AN), there is a lack of knowledge into the processes that occur with the development and maintenance of the disease. This has impeded the development of novel treatment approaches that may prove more effective than traditional medical models of therapy. To improve the prognosis of these long-standing presentations, an understanding as to how and why the AN disease progresses is required. It was therefore the aim of the current study to investigate the transition of AN from earlier to later stages.

METHOD

The study adopted a narrative inquiry approach and a total of 11 women with long-standing AN participated in an interview. The newly developed photovoice method assisted in data collection with typologies of chronic illness facilitating the emergence of salient themes.

RESULTS

The qualitative analysis resulted in the identification of five themes: (a) transition, (b) trauma, (c) functionality, (d) identity, and (e) failure of current models of treatment.

CONCLUSIONS

Together with identifying key themes, the study provides insight into some possible reasons why current treatment models are failing to promote recovery. Future research examining the effectiveness of treatment that targets underlying causes and maintaining factors of the illness are suggested. Additional education for health professionals is also recommended in order to reduce the trauma that is currently being experienced by some patients with a long-standing illness.

Lived experience perspectives on labeling and defining long-standing anorexia nervosa

OBJECTIVE

Since efforts to stage anorexia nervosa (AN) revealed the existence of various presentations, research into the long-standing subgroup has increased. A change in treatment has been proposed with the intention to use more effective evidence-based methods that target symptoms of the long-standing presentation and improve prognosis. A barrier in achieving this goal in both research and clinical contexts is the lack of a consistent label and definition. This makes the ability to assess, recruit and treat these presentations difficult. Investigations into how this subgroup may be differentiated from other stages of the disorder have included the opinions of practitioners and researchers with little consideration for the perspectives of individuals living with this illness. It was the aim of the current study to investigate lived experience perspectives on the way long-standing AN should be labeled and defined.

METHODS

Data were collected through a semi-structured interview within a narrative inquiry framework. This approach is beneficial when examining processes that occur over time, such as investigations into a long-term illness. A total of 11 women with a presentation of long-standing AN participated in an interview. Data were divided into two categories for analysis based on the association to labeling or defining the features of the long-standing AN illness.

RESULTS

Two labels emerged during the analysis with participants describing a preference for the use of 'severe and enduring' over 'chronic' when referring to their presentation of AN. When defining the illness, the most preferred criterion was illness duration with mixed perspectives for the use of previously failed treatment attempts. Participants described a consistent dislike for the use of low body weight as a feature in the defining of the illness.

CONCLUSIONS

The current study describes how individuals with a lived experience prefer to have the long-standing AN presentation labeled and defined. It is the hope of the authors that these insights will be adopted into any guidelines developed to ensure individuals most affected by this disorder have a voice and continue to be given the opportunity to contribute to topics related to their illness. Anorexia nervosa (AN) is a complex illness that has been divided into stages based on the severity of symptoms. Little is known about the AN stage that persists over lengthy periods of time with research pursuits underway to determine characteristics that allow this disorder to persevere. A barrier in researching and treating these individuals is the lack of a consistent label to refer to these presentations and criteria that will allow us to identify this stage of AN. The aim of the current study was to determine how individuals with a lived experience of long-standing AN prefer to have their illness labeled and defined. A total of 11 women who had experienced this stage of AN were interviewed with the majority of participants reporting to prefer the label 'severe and enduring' over the term 'chronic'. Additionally, most of the participants had a preference for defining their illness based on the duration of time the illness had persisted with mixed opinions for using the number of previously unsuccessful treatment attempts as criterion. The authors are hopeful that any guidelines established for labeling and defining long-standing AN will incorporate the perspectives of individuals with a lived experience of the illness.

A pilot study exploring the effect of repetitive transcranial magnetic stimulation (rTMS) treatment on cerebral blood flow and its relation to clinical outcomes in severe enduring anorexia nervosa

BACKGROUND

Repetitive transcranial magnetic stimulation (rTMS) is a novel treatment option for people with severe enduring anorexia nervosa (SE-AN), but associated neurobiological changes are poorly understood. This study investigated the effect of rTMS treatment on regional cerebral blood flow (CBF) and whether any observed changes in CBF are associated with changes in clinical outcomes in people with SE-AN.

METHODS

As part of a randomised sham-controlled feasibility trial of 20 sessions of high-frequency rTMS to the left dorsolateral prefrontal cortex, 26 of 34 trial participants completed arterial spin labelling (ASL) functional magnetic resonance imaging (fMRI) to quantify regional and global resting state CBF before (pre-randomisation baseline) and after real or sham treatment (1-month post-randomisation). A group of healthy females (n = 30) were recruited for baseline comparison. Clinical outcomes, including BMI, and depression and anxiety symptoms, were assessed at baseline, 1-, 4-, and 18-months post-randomisation.

RESULTS

No group differences in regional CBF were identified between the SE-AN and healthy comparison participants. A significant treatment-by-time interaction in a medial temporal lobe cluster with the maximal peak in the right amygdala was identified, reflecting a greater reduction in amygdala CBF following real rTMS compared to sham. Participants with the greatest rTMS-related reduction in amygdala CBF (i.e., between baseline and 1-month post-randomisation) showed the greatest sustained weight gain at 18-months post-randomisation. Higher baseline CBF in the insula predicted greater weight gain between baseline and 1-month post-randomisation and between baseline and 4-months post-randomisation.

CONCLUSIONS

This exploratory pilot study identified rTMS treatment related changes in CBF in adults with SE-AN and these were associated with changes in weight. Our preliminary findings also suggest that CBF (as measured by ASL fMRI) may be a marker of rTMS treatment response in this patient group. Future rTMS studies in AN should employ longitudinal neuroimaging to further explore the neurobiological changes related to rTMS treatment.

Outcomes for adults with anorexia nervosa who do not respond early to outpatient treatment

OBJECTIVE

To better understand those patients with anorexia nervosa who do not show early response to treatment and are likely to have poorer outcome.

METHOD

From an existing data set of 187 patients with anorexia nervosa across 22 eating disorder outpatient services in the United Kingdom, participants who had started treatment and had at least one body mass index (BMI) observation in the first 6 weeks of treatment were eligible for these secondary analyses (N = 65), a latent class analysis of BMI change over the first 6 weeks of treatment. Fifty-six patients showed no early change in BMI. We used logistic regression to examine predictors of good outcome in the 40 participants who had 12-month follow-up data. Predictors included global EDE-Q, negative affect (Depression, Anxiety, and Stress Scales) and functional impairment (Work and Social Adjustment Scale).

RESULTS

Good outcome was achieved by 23% of patients and remission by 15%. Good outcome was predicted by less functional impairment at baseline.

DISCUSSION

Further work that can identify sub-groups of patients with anorexia nervosa who do not achieve good outcome after treatment will inform the development of targeted engagement approaches.

Inpatients with severe-enduring anorexia nervosa: Understanding the "enduringness" specifier

Background

Despite the need for a common definition of severe and enduring anorexia nervosa (SE-AN) with the overarching goal to optimize treatments, this definition still is being debated. Therefore, in this study we conducted an in-depth investigation of the history of AN and its clinical outcomes on inpatients with AN to ascertain the eventual “profiles” for individuals with varying durations of the illness (DOI).

Methods

We recruited 169 inpatients with AN, grouping them according to DOI: <3 years (short duration, SD-AN); 3–6.99 years (medium duration, MD-AN); and ≥7 years (long duration, LD-AN). We then performed a self-report and interview-based investigation of AN history, clinical data, eating, and general psychopathology, including personality, premorbid traits, stage of change, and quality of life. We measured the clinical outcomes for hospitalization as well.

Results

The majority of the measures did not differ across groups. Those with LD-AN were older and diagnosed mostly with the binge-purging AN subtype, failed more previous AN-related treatments, reported a lower lifetime body mass index, and trended toward a younger age at onset when compared to the other groups. All patients responded equally well to hospitalization, but patients with SD-AN improved less in drive for thinness and body-related concerns.

Conclusions

We did not find the “enduringness” of AN to be a specifier of severity. Hospitalization was effective for those with LD-AN and MD-AN, while interventions for the core cognitive aspects of over-evaluation of body shape should be offered to patients with SD-AN.

The Maudsley Anorexia Nervosa Treatment for Adults (MANTRA): a feasibility case series of an integrated group based approach

BACKGROUND

Individuals with Anorexia Nervosa (AN) typically struggle in social and emotional contexts. An Integrated Group Based approach for the delivery of MANTRA - The Maudsley Anorexia Nervosa Treatment for Adults - extends current NICE recommended therapy by augmenting treatment with opportunities for experiential practice in a group context. A feasibility case series, delivered across three NHS community services is presented.

METHODS

The design was a case series of four Integrated Group MANTRA treatments delivered across three NHS sites (N = 29). Feasibility data of: retention, acceptability and effectiveness; alongside the qualitative capture of participant experiences of treatment is presented.

RESULTS

Primary outcomes suggest treatment acceptability. Participants committed to treatment with only 2 dropouts. There was significant change with medium effect sizes for eating disorder cognitions and symptoms (as measured by the global score on EDEQ) and BMI. Core themes emerging from qualitative analysis captured the value of the relational aspect of the treatment, the incorporation of experiential methods, and the opportunity to draw on the support of the group members to reduce shame and stigma.

CONCLUSIONS

An Integrated Group based MANTRA approach is a feasible and effective alternative intervention for community Eating Disorder services.

A systematic review of interventions to support transitions from intensive treatment for adults with anorexia nervosa and/or their carers

AIM

In the short term, intensive treatment focusing on restoring weight for anorexia nervosa can remediate many symptoms. However, there is a high level of relapse after discharge. This paper examines interventions developed to bridge the transition from intensive to less intensive forms of treatment for adult anorexia nervosa.

METHOD

We undertook a systematic review of the literature on interventions aimed at providing transition support. The Template for Intervention Description and Replication was used to describe components of the transition interventions. Patient's drop-out rates, weight, eating disorder psychopathology and mood data were extracted at end of treatment and follow-up to describe preliminary efficacy.

RESULTS

Fourteen studies were selected: nine used psychological interventions delivered through face-to-face talking therapy or guided self-help, three examined the use of fluoxetine and two assessed stepped-care approaches. Transition support was delivered to patients in 11 studies, to patients and carers in two studies, and carers alone in another study.

CONCLUSIONS

There was a great heterogeneity in the content and structure of the transition interventions evaluated. Overall, drop-out rates were lower for psychological support than pharmacological interventions or stepped-care approaches. Changes in eating disorder outcomes and mood were small to moderate throughout for studies that included a comparison group.

Personality disorder traits, obsessive ideation and perfectionism 20 years after adolescent-onset anorexia nervosa: a recovered study

PURPOSE

The many studies examining the relationship between anorexia nervosa (AN) and personality abnormalities have observed high comorbidity. However, no definitive studies to date have established whether there is a causal connection or whether it is a complication. The current study aimed to explore the nature of the relationship between personality disorder (PD) traits, obsessionality and perfectionism, using a study design that allows the testing of some comorbidity models.

METHODS

Twenty-nine women were recruited from a group of former AN patients treated during their adolescence in a specialized unit around 20 years before the time of this study. They were divided into two groups according to the current presence of eating disorder (ED) symptoms (current-ED, n = 11; recovered, n = 18). Both groups were compared to a matched control group (n = 29) regarding current PD traits, obsessive beliefs and perfectionism.

RESULTS

Borderline PD traits, most cluster C PD traits and overestimation of threat were more common in the current-ED group than in the control and recovered groups. Obsessive-compulsive PD traits, intolerance of uncertainty, and perfectionism were also significantly more prevalent in the current-ED group compared to controls but did not reach significance when compared to the recovered group. No significant differences were found between the recovered and control groups.

CONCLUSION

Our results mostly support the personality abnormalities observed as a transient effect related to the presence of ED psychopathology in patients with adolescent-onset AN.

Optimising care pathways for adult anorexia nervosa. What is the evidence to guide the provision of high-quality, cost-effective services?

The aim of this paper is to consider how changes in service planning and delivery might improve the care pathways for adult anorexia nervosa. Although anorexia nervosa has a long history in Europe, its framing as a mental disorder is quite recent. The changing forms and increasing epidemiology of eating disorders has led to the expansion of specialised services. Although some services provide care over the entire clinical course, more often services are divided into those that care for children and adolescents or adults. The transition needs to be carefully managed as currently these services may have a different ethos and expectations. Services for adults have a broad range of diversity (diagnostic subtype, medical severity, comorbidity, stage of illness and psychosocial functioning) all of which impacts on prognosis. A tailored, approach to treatment planning could optimise the pathway. Facilitating early help seeking and rapid diagnosis in primary care and reducing specialised services waiting lists for assessment and treatment could be a form of secondary prevention. The use of precision models and /or continuous outcome monitoring might reduce the third of patients who require more intensive care by applying augmentation strategies. Finally, gains from intensive care might be sustained by relapse prevention interventions and community support to bridge the transition home. Together these measures might reduce the proportion of patients (currently a third) with ill health for over 20 years. For this group rehabilitation strategies may improve functioning until new treatment emerge.

The impact of duration of illness on treatment nonresponse and drop-out: Exploring the relevance of enduring eating disorder concept

OBJECTIVE

There are no generally accepted definitions or markers of treatment nonresponse in eating disorders (EDs). The aim of this paper was to examine how the duration of illness and other potential prognostic markers impacted on nonresponse and drop-out from treatment across different EDs subtypes.

METHODS

A total sample of 1199 consecutively treated patients with EDs, according to Diagnostic and Statistical Manual of Mental Disorders, fifth edition criteria, participated in this study. Kaplan-Meier curves were calculated for each ED diagnosis in which the probability of recovery was plotted against the duration of illness.

RESULTS

Full remission was more likely for people with binge eating disorder (BED; 47.4%) and anorexia nervosa (AN; 43.9%) compared to bulimia nervosa (BN; 25.2%) and other specified feeding and EDs (OSFED; 23.2%). The cut-off points for the duration of the illness related with high likelihoods of poor response was 6-8 years among OSFED, 12-14 years among AN and BN and 20-21 years among BED. Other variables predicting nonresponse included dysfunctional personality traits.

CONCLUSIONS

Nonresponse to treatment is associated with duration of illness which is in turn associated with poor response to previous treatment. However, there was no evidence for staging the illness using specific duration of illness criteria. Nevertheless, the shorter temporal trajectory for OSFED suggests that early interventions may be of importance for this group.

Length of stay for anorexia nervosa: Systematic review and meta-analysis

OBJECTIVE

Evidence regarding global trends in length of stay for patients with anorexia nervosa is limited. The aim of this study is to conduct a meta-analysis examining the length of stay for anorexia nervosa patients globally, and to investigate moderators of the variance.

METHOD

Medline, EMBASE and PsycINFO were searched for studies published up to January 2019. Two independent reviewers assessed the eligibility of each report based on predefined inclusion criteria. A meta-analysis was performed to calculate a pooled mean length of stay using the random-effects model. Subgroup analyses and meta-regression were conducted to explore potential sources of heterogeneity between studies.

RESULTS

Of 305 abstracts reviewed, 71 studies met the inclusion criteria, generating 111 datasets. The pooled mean length of stay (95% confidence interval) was 76.3 days (73.3, 79.4) using the random-effects model, with marked variation across countries and time. Heterogeneity between studies was explained by age and admission body mass index.

CONCLUSIONS

This meta-analysis found that although clinical features do contribute to length of admissions for anorexia nervosa, there are also global and temporal variations. Future research should provide an in-depth analysis of why and how this variation exists and what the impact is on the well-being of people with anorexia nervosa.

Rehospitalization and "Revolving Door" in Anorexia Nervosa: Are There Any Predictors of Time to Readmission?

Objective: Anorexia nervosa (AN) is a severe psychiatric illness with multifactorial etiology and unsatisfactory treatment outcomes. Hospitalization is required for a substantial number of patients, and readmission (RA) commonly occurs. Some individuals need multiple hospitalizations sometimes over a short amount of time, thus, delineating the "revolving door" (RD) phenomenon. However, very little is known about readmissions and their frequency in AN. Therefore, we aimed to longitudinally investigate readmissions in AN in order to: (a) characterize patients with AN who need readmission (i.e., RA-AN), sometimes rapidly (RD-AN); (b) ascertain differences between RA-AN and non-RA-AN groups during baseline hospitalization; (c) investigate as to whether clinical or psychometric parameters worsened on RA; and (d) analyze predictors of time-to-readmission in AN. Methods: A total of 170 inpatients with AN were enrolled at their baseline hospitalization; all their subsequent rehospitalizations were recorded with a longitudinal design by which each patient has been observed for 3 years. Patients were classified as RD-AN if requiring a readmission <12 months since last discharge. Clinical characteristics were measured upon admission and discharge for each hospitalization, and at all time points, patients completed questionnaires assessing eating and general psychopathology, and body shape concerns. Results: Sixty-seven patients (39.4%) needed at least one readmission and 62 (92.5% of RA-AN) reported RD. Compared with non-RA-AN, those with RA-AN were younger, reported a shorter duration of illness, and were more frequently diagnosed with AN-BP. Also, greater severity of anxious and depressive symptoms and body shape concerns emerged in the RA-AN group. The outcome of baseline hospitalization did not differ between groups, and only depressive symptoms worsened at readmission. Shorter duration of AN and low weight gain during baseline hospitalization predicted early readmission but did not survive statistical control. In contrast, high scores on drive for thinness upon baseline hospital entry robustly predicted a shorter time to readmission even after statistical control. Discussion: Individuals with AN who require readmission do so over a short period notwithstanding a positive treatment outcome during their baseline hospitalization. Shorter time-to-readmission can be predicted mostly in case of marked drive for thinness and poor weight gain at baseline hospital admission.

The validity of the fifth and the 10th Body Mass Index percentile as weight cut-offs for anorexia nervosa in adolescence: No evidence from quantitative and network investigation of psychopathology

OBJECTIVE

Although the fifth Body Mass Index (BMI) percentile is the Diagnostic and Statistic Manual of Mental Disorders -5 weight cut-off criterion to diagnose anorexia nervosa (AN) in children and adolescents, its validity has not been proved, and the 10th percentile value is often applied. We aimed to investigate the diagnostic validity of these weight cut-offs.

METHOD

We compared general and eating-disorder (ED) specific psychopathology in 380 adolescents with AN or atypical AN. They were grouped first with respect to the fifth BMI percentile and then with respect to the 10th BMI percentile and differences between groups were analysed. Network analyses on psychopathological symptoms were also conducted.

RESULTS

Adolescents with BMI above the fifth and the 10th percentile reported more severe ED specific symptomatology compared to those with BMI below these cut-offs. No significant differences emerged between groups neither in general psychopathology nor in the network structure of psychopathology.

CONCLUSIONS

The fifth BMI percentile does not discriminate psychopathology severity in adolescents with AN. From the psychopathology perspective, our findings suggest that adolescents with atypical AN deserve the same clinical and research attention as those with full AN. Future studies are needed to identify a more accurate definition of underweight in adolescents.

Developments in the psychological treatment of anorexia nervosa and their implications for daily practice

PURPOSE OF REVIEW

Our aim is to give an overview of the recent literature on psychological treatment for young adults and adults with anorexia nervosa and to discuss the implications of the findings for clinical practice.

RECENT FINDINGS

Three systematic reviews and meta-analyses have recently been published on psychological treatments for anorexia nervosa. Treatment outcomes are still modest and mainly focus on weight outcome, although outcomes for eating disorder disease and quality of life have also been reported. Adhering to a treatment protocol might lead to faster and better results.

SUMMARY

For children and adolescents with anorexia nervosa, the major guidelines recommend a family-based treatment. The treatments of choice for young adults and adults with anorexia nervosa are the Maudsley Anorexia Nervosa Treatment for Adults (MANTRA), Cognitive Behaviour Therapy-Enhanced (CBT-E) and Specialist Supportive Clinical Management (SSCM), but none of these treatments seem to be superior. In search of other ways to improve outcome, shared decision making may be a way to help patients become more involved in their treatment, enhance their motivation and consequently improve the outcome.

Relationship between eating disorder duration and treatment outcome: Systematic review and meta-analysis

OBJECTIVE

This systematic review and meta-analysis examine the contribution of duration to treatment outcome for eating disorders.

METHOD

Studies (n = 31) were identified that examined associations (r) between duration and 45 different outcomes. We were unable to extract r for seven studies (9 outcomes) and extracted r for 36 outcomes across 24 studies (2,349 participants). Indicators of treatment outcome were heterogeneous and thus a series of different meta-analyses, aimed at increasing homogeneity, were conducted.

RESULTS

First, we examined the average effect size for one primary eating disorder related outcome from each of the 24 studies. There was no association between duration and treatment outcome (r = .05, 95% CI: -.03:.13), with high heterogeneity. Second, we conducted three sub-group analyses to explore possible sources of heterogeneity (diagnosis: anorexia nervosa versus bulimia nervosa; nature of the outcome: binary versus continuous; or type of outcome: binary indicator of recovery, eating disorder psychopathology, weight gain). There was no significant moderation or associations between duration and outcome (ranging from .02-.08), with low to medium heterogeneity. Third, two stand-alone analyses examined outcomes related to weight gain (n = 8) and eating disorder psychopathology (n = 5), with nonsignificant rs of .23/-.06, respectively. High levels of heterogeneity were present.

DISCUSSION

Duration did not influence treatment outcome across any of our meta-analyses. Increasing homogeneity and power will allow more stable estimates of the impact of duration on outcome to be calculated; to this end, future treatment studies should include outcome related to weight gain (anorexia nervosa) and improvements in eating disorder psychopathology.

Assessing the impact of First Episode Rapid Early Intervention for Eating Disorders on duration of untreated eating disorder: A multi-centre quasi-experimental study

BACKGROUND

Duration of untreated eating disorder (DUED), that is, the time between illness onset and start of first evidence-based treatment, is a key outcome for early intervention. Internationally, reported DUED ranges from 2.5 to 6 years for different eating disorders (EDs). To shorten DUED, we developed FREED (First Episode Rapid Early Intervention for EDs), a service model and care pathway for emerging adults with EDs. Here, we assess the impact of FREED on DUED in a multi-centre study using a quasi-experimental design.

METHODS

Two hundred and seventy-eight patients aged 16-25, with first episode illness of less than 3 years duration, were recruited from specialist ED services and offered treatment via FREED. These were compared to 224 patients, of similar age and illness duration, seen previously in participating services (treatment as usual [TAU]) on DUED, waiting times and treatment uptake.

RESULTS

FREED patients had significantly shorter DUED and waiting times than TAU patients. On average, DUED was reduced by ∼4 months when systemic delays were minimal. Furthermore, 97.8% of FREED patients took up treatment, versus 75.4% of TAU.

DISCUSSION

Findings indicate that FREED significantly improves access to treatment for emerging adults with first episode ED. FREED may reduce distress, prevent deterioration and facilitate recovery.

"I'm not a teenager, I'm 22. Why can't I snap out of it?": a qualitative exploration of seeking help for a first-episode eating disorder during emerging adulthood

BACKGROUND

Eating disorders (EDs) typically have their onset during adolescence or the transition to adulthood. Emerging adulthood (~ 18-25 years) is a developmental phase which conceptually overlaps with adolescence but also has unique characteristics (e.g. increased independence). Emerging adults tend to come to ED services later in illness than adolescents, and emerging adulthood's unique characteristics may contribute to such delays.

OBJECTIVE

This study aimed to explore attitudes towards ED symptoms, and their implications for help-seeking, amongst emerging adults receiving ED treatment through FREED, an early intervention care pathway.

METHOD

Participants were 14 emerging adults (mean age 20.9 years; SD = 2.0), all currently receiving specialist treatment for a first-episode, recent-onset (< 3 years) ED. Semi-structured interviews relating to experiences of help-seeking were conducted, and data were analysed thematically.

RESULTS

Symptom egosyntonicity, gradual reappraisal and feelings of exclusion from ED discourse were key attitudinal phases prior to help-seeking, each of which had distinct implications for help-seeking.

CONCLUSIONS

Emerging adults with first-episode EDs show a distinct set of help-seeking-related challenges and opportunities (e.g. help-seeking for others; help-seeking at transitions; self-sufficiency). This research might be used to inform the development and evaluation of interventions which aim to facilitate help-seeking amongst emerging adults with first-episode recent-onset EDs.

Severe and enduring anorexia nervosa: Update and observations about the current clinical reality

Several objectives underlie the current article. First, to review historical diagnostic issues and clinical strategies for treating SE-AN. Second, to provide an overview of recent evidence informed strategies and clinical innovations for the treatment of SE-AN. Third, based on the authors' collective clinical and research experience, we offer eight observations that we believe capture the current clinical experience of patients with SE-AN. Some of these observations represent empirically testable hypotheses, but all are designed to generate a meaningful discussion about the treatment of this group of individuals with eating disorders. Finally, we hope to call clinicians, scientists, professional organizations, advocates, and policy makers to action to attend to critical issues related to the care of individuals with SE-AN. We believe that an international discussion could clarify areas of need for these patients and identify opportunities for clinical innovation that would enhance the lives of individuals with SE-AN and their families.

Repetitive transcranial magnetic stimulation treatment in severe, enduring anorexia nervosa: An open longer-term follow-up

OBJECTIVE

This study assessed longer-term outcomes from a randomised controlled feasibility trial of 20 sessions of real versus sham high-frequency repetitive transcranial magnetic stimulation (rTMS) to the left dorsolateral prefrontal cortex in adults with severe, enduring anorexia nervosa (SE-AN).

METHODS

Thirty participants who completed the original study protocol were invited to take part in an open follow-up (18-months post-randomisation), assessing body mass index (BMI), eating disorder (ED) symptoms and other psychopathology.

RESULTS

Twenty-four participants (12 each originally allocated to real/sham) completed the 18-month follow-up. Ten of 12 participants who originally received sham treatment had real rTMS at some stage during the follow-up. A medium between-group effect size was seen for BMI change from baseline to 18-months, favouring those originally allocated to real rTMS. In this group at 18-months, five participants were weight recovered (BMI ≥18.5 kg/m² ), compared with one participant in the original sham group. Both groups showed further improvement in ED symptoms during the follow-up. Effects on mood were largely maintained at follow-up, with catch-up effects in the original sham group.

CONCLUSIONS

Findings suggest that rTMS treatment effects on mood are durable and that BMI and ED symptom improvements need time to emerge. Large-scale trials are needed.
