Intensive enhanced cognitive behavioural therapy for severe and enduring anorexia nervosa: A longitudinal outcome study

Using CBT-E in the Treatment of Anorexia Nervosa With Comorbid Obsessive-Compulsive Personality Disorder and Clinical Perfectionism

OBJECTIVE

Several studies and clinical vignettes emphasize the association between eating disorders and maladaptive personality traits that should be targeted in treatment to strengthen the therapeutic prognosis and outcome. The aim of this paper is to present a single case study with a patient showing comorbid Anorexia Nervosa (AN) and Obsessive-Compulsive Personality Disorder (OCPD) with perfectionistic traits, using Cognitive Behavioral Therapy for Eating disorders (CBT-E) and Perfectionism (CBT-P).

METHODS

The patient, a young girl aged 17 years, was underweight when entering therapy and received an enhanced version of CBT-E with 40 sessions as recommended in the manual. The treatment was adjusted for adolescents with a heightened focus on motivation, therapeutic alliance, and parental involvement. The clinical interventions were structured in accordance with CBT-E for adolescents with six added sessions targeting clinical perfectionism based on CBT-P focusing on over-evaluation of achievements in addition to weight and shape.

RESULTS

The patient showed a gradual decrease in eating disorder symptoms and perfectionism through the 1-year treatment. She was normal weight by the end of therapy, enjoyed varied food, was more socially engaged and balanced clinical perfectionism with more healthy strivings and standards. She was also able to express her need for boundaries and rest to family, friends and her sports team. At the final assessment, she did not fulfill diagnostic criteria for AN or OCPD with perfectionistic traits, but she showed some symptoms in achievement situations that was targeted by information and preventive interventions.

CONCLUSION

In accordance with the manual for CBT-E, perfectionism should be targeted as part of the treatment for eating disorders when in the clinical range. This was done in the present case with AN and perfectionistic traits within a comorbid OCPD, using elements of CBT-P that showed positive results and meaningful changes for the patient.

Optimising Psychosocial Interventions for People With Severe and Enduring Eating Disorders (SEED) Perspectives of Healthcare Professionals in Ireland: A Qualitative Study

To date, no studies have explored healthcare professionals' perceptions on the acceptability and effectiveness of psychosocial interventions for patients with severe and enduring eating disorders in Ireland. The aims of this study were to explore how healthcare professionals view the use of psychosocial interventions for patients with severe and enduring eating disorders and how these approaches can be improved. A qualitative study design was utilised to explore perceptions and opinions. Semi-structured, one-to-one interviews were used to collect data from healthcare professionals (n = 16) in mental health settings. Interviews were audio-recorded and transcribed verbatim before being analysed using thematic analysis. Four themes were identified: (1) therapeutic relationship, (2) patient-centred approaches, (3) co-morbidities and (4) pathway of care and services. Findings strongly suggest the need for patients with severe and enduring eating disorders to set their own goals to improve treatment outcomes and quality of life. Furthermore, findings also suggest a strong correlation between a history of trauma and the diagnosis of severe and enduring eating disorders. Therefore, training for healthcare professionals to provide trauma-informed care is needed.

Improving eating disorder care for underserved groups: a lived experience and quality improvement perspective

Improvements to eating disorder (ED) care are urgently needed in the United Kingdom (UK) and around the world. Informed by my lived experiences, independent research, and involvement in the underappreciated field of quality improvement (QI), I have written this article to offer ideas on how to improve individuals' access to and experiences of ED care. As I live in the UK, my lived and QI experiences are of the UK's National Health Service (NHS). However, much of this article's content can be applied broadly to healthcare providers around the world, as similar ED care improvements are needed internationally. Furthermore, this commentary is informed by the latest international research.In this paper, I will identify and discuss 12 groups of individuals whom I believe are more likely to be underserved in ED care. The 12 'underserved groups' (USGs) are as follows: [USG. 1] People with longstanding EDs and/or older-age ED sufferers; [USG. 2] Younger children/preadolescents; [USG. 3] People with under-recognised/underappreciated EDs; [USG. 4] People with higher weights; [USG. 5] People with comorbidities; [USG. 6] People with neurodevelopmental conditions (neurodiverse people); [USG. 7] Digitally excluded people; [USG. 8] Socioeconomically and/or sociogeographically disadvantaged people; [USG. 9] Ethnic/racial minorities; [USG. 10] Sexual and gender-diverse people; [USG. 11] Males; [USG. 12] Caregivers/loved ones.ED sufferers/caregivers are also an underserved group as a whole in general mental health care, so broader considerations for improving ED care will be explored in a future publication; these include stigma, research biases, inadequate clinical monitoring and diagnosing, poor-quality treatments, disorganised service transitions, systemic problems/inefficiencies, and underfunding/under-resourcing. Specific recommendations for USGs 1-12 must be considered alongside these and other broader issues. Throughout both articles, I advocate a humanistic care model/approach based on the inexpensive principles of compassion, hope, empathy, appreciation (of identity), and patience ('CHEAP').

Applying integrated enhanced cognitive behaviour therapy (I-CBTE) to severe and longstanding eating disorders (SEED) Paper 2: An in-depth case study for clinicians

BACKGROUND

This case study examines the application of Integrated Enhanced Cognitive Behavioural Therapy (I-CBTE) for a patient with severe, longstanding anorexia nervosa and multiple comorbidities, including organic hallucinosis, complex post-traumatic stress disorder (CPTSD), and severe self-harm. Such complex presentations often result in patients falling between services, which can lead to high chronicity and increased mortality risk. Commentaries from two additional patients who have recovered from severe and longstanding anorexia nervosa are included.

CASE STUDY

The patient developed severe anorexia nervosa and hallucinosis after a traumatic brain injury in 2000. Despite numerous hospitalisations and various psychotropic medications in the UK and France, standard treatments were ineffective for 17 years. However, Integrated Enhanced Cognitive Behaviour Therapy (I-CBTE) using a whole-team approach and intensive, personalised psychological treatment alongside nutritional rehabilitation proved effective.

METHODS

In this paper, we describe the application of the I-CBTE model for individuals with severe, longstanding, and complex anorexia nervosa, using lived experience perspectives from three patients to inform clinicians. We also outline the methodology for adapting the model to different presentations of the disorder.

OUTCOMES

The patient achieved and maintained full remission from her eating disorder over the last 6 years, highlighting the benefit of the I-CBTE approach in patients with complex, longstanding eating disorder histories. Successful treatment also saved in excess of £360 k just by preventing further hospitalisations and not accounting for the improvement in her quality of life. This suggests that this method can improve outcomes and reduce healthcare costs.

CONCLUSION

This case study, with commentaries from two patients with histories of severe and longstanding anorexia nervosa, provides a detailed description of the practical application of I-CBTE for patients with severe and longstanding eating disorders with complex comorbidities, and extensive treatment histories. This offers hope for patients and a framework for clinicians to enhance existing treatment frameworks, potentially transforming the trajectory of those traditionally deemed treatment resistant.

RECOMMENDATIONS

We advocate the broader integration of CBT for EDs into specialist services across the care pathway to help improve outcomes for patients with complex eating disorders. Systematic training and supervision for multidisciplinary teams in this specialised therapeutic approach is recommended. Future research should investigate the long-term effectiveness of I-CBTE through longitudinal studies. Patient feedback on experiences of integrated models of care such as I-CBTE is also needed. In addition, systematic health economics studies should be conducted.

Exploring body uneasiness in severe and enduring eating disorders: insights from clinical practice

INTRODUCTION

Body uneasiness is a central facet of body image disturbances observed in individuals with eating disorders (EDs). This study aimed to address gaps in understanding body uneasiness in severe and enduring eating disorders (SE-EDs) and explore variations in psychopathology between individuals with different durations of the disorder. We hypothesized that patients with SE-ED might develop habitual behaviors that contribute to ambivalence toward treatment and the persistence of symptoms.

METHODS

A sample of 360 ED patients was evaluated at the beginning and end of a specialized intensive rehabilitation program. All patients completed the Eating Disorder Examination Questionnaire (EDE-Q) and the Body Uneasiness Test (BUT). They were divided into two groups: SE-ED (> 7 years) and acute (aED, < 3 years) duration.

RESULTS

Compulsive self-monitoring showed a significant change between the start and end of treatment, differing between groups, with a larger change observed in SE-ED (p < 0.048). In SE-ED, it was associated with lower chances of dropout (p = 0.044), opposite to aED (p = 0.009). Treatment responses were primarily related to eating psychopathology, further highlighting differences between the two groups.

CONCLUSIONS

This study underscores the possible presence of a habit in SE-ED and the importance of tailoring interventions to address unique needs based on the duration of the disorder. Furthermore, it highlights the need for further research to improve treatment outcomes in SE-EDs.

Harm reduction in severe and long-standing Anorexia Nervosa: part of the journey but not the destination-a narrative review with lived experience

Questions remain about the best approaches to treatment for the subset of patients with severe and long-standing Anorexia Nervosa, commonly described in the literature as "Severe and Enduring Anorexia Nervosa." When discussing the optimal strategies and goals for treating this group, there is uncertainty over whether to focus on refining current treatment methods or exploring alternative approaches. One such alternative is "harm reduction," which has generated a wave of positive interest from patients and clinicians alike because of its emphasis on individual autonomy, personal goals and quality of life. While harm reduction can provide an attractive alternative to seemingly endless cycles of ineffective treatment, this narrative review builds on previous work to highlight the inadequate terminology and possible dangers of considering harm reduction as the endpoint of treatment. In conjunction with perspectives from a lived experience author, we consider wider contextual and ethical issues in the field of eating disorders, which should inform the role of harm-reduction approaches in this patient group.

Comparing hospitalized adult patients with chronic anorexia nervosa with versus without prior hospitalizations

BACKGROUND

Anorexia nervosa (AN) is a severe psychiatric disorder, from which recovery is often protracted. The role of prior specialized inpatient treatment on subsequent treatment attempts for adults with chronic AN and predictors of treatment response for severe and enduring AN (SE-AN) are needed to improve outcomes.

METHOD

Participants (N = 135) with chronic AN (ill ≥7 years) admitted to an integrated inpatient-partial hospitalization eating disorders (ED) unit with prior ED hospitalization(s) (+ PH; n = 100) were compared to those without prior ED hospitalizations (-PH; n = 35) on admission characteristics (BMI, length of illness, outpatient ED treatment history, symptomatology (ED, anxiety, and depressive), history of suicide attempts or non-suicidal self-injury (NSSI)), treatment motivation and recovery self-efficacy, and discharge outcomes (discharge BMI, rate of weight gain, length of stay, clinical improvement).

RESULTS

Groups were similar with regard to age, years ill, and admission BMI. The + PH group had lower desired weight, lifetime nadir BMI and self-efficacy for normative eating, and higher state and trait anxiety than the -PH group. +PH were also more likely to endorse history of NSSI and suicide attempt. Regarding discharge outcomes, most patients achieved weight restoration at program discharge (mean discharge BMI = 19.8 kg/m2). Groups did not differ on rate of weight gain, likelihood of attending partial hospital, partial hospital length of stay, program discharge BMI, or likelihood of clinical improvement (p's > 0.05) although inpatient length of stay was longer for the + PH group.

CONCLUSIONS

Participants with chronic AN + PH exhibited more severe psychiatric comorbidity and lower self-efficacy for normative eating than AN -PH, however short-term discharge outcomes were similar. Future research should determine whether weight restoration and targeting comorbidities impacts relapse risk or need for rehospitalization among chronic and severe + PH. Despite similar illness durations, those with chronic AN -PH may be able to transition to partial hospital earlier. Conversely there is risk of undertreatment of chronic AN + PH given the recent shift promoting briefer self-directed admissions for adults with SE-AN. Research comparing + PH and -PH adults with chronic AN may facilitate efforts to individualize care and characterize relapse risk following intensive treatment.

Clinical and scientific review of severe and enduring anorexia nervosa in intensive care settings: introducing an innovative treatment paradigm

BACKGROUND

Anorexia nervosa is a serious and potentially lethal psychiatric disorder. Furthermore, there is significant evidence that some individuals develop a very long-standing form of the illness that requires a variety of different treatment interventions over time.

OBJECTIVE

The primary goal of this paper was to provide a review of treatment strategies for severe and enduring anorexia nervosa (SE-AN) with the particular focus on treatments involving hospital care. Additionally, we wish to highlight a contemporary approach to such care and provide qualitative reactions to this model from both staff and patients.

METHODS

A selective and strategic review of the treatment literature for SE-AN was conducted for the current paper. Emphasis was placed on clinical or scientific papers related to hospital-based care. Additionally, staff who work on a specific inpatient eating disorder unit with a substantial treatment program for SE-AN, along with a number of SE-AN patients were surveyed regarding their experiences working on, or receiving treatment on the unit. Importantly, the staff of this unit created a specific treatment protocol for individuals receiving hospital care. The results of the highlight both advantages and challenges of a hospital-based protocol oriented toward emphasizing quality of life, medical stability, and a health-promoting meal plan.

DISCUSSION

While there is general inconsistency with the type of treatment that is best suited to individuals with SE-AN, this is particularly true for higher levels of care that rely on inpatient hospital units or residential treatment settings. This is a highly significant clinical topic in need of further clinical and scientific examination.

A case report about anorexia nervosa and ischemic stroke: what can we learn?

INTRODUCTION

Anorexia Nervosa (AN) is a complex psychiatric illness, characterized by a high risk of developing cardiovascular complications. Given the high risk of vascular diseases in patients with AN, we can assume that patients with severe AN have a high risk of developing ischemic stroke. However, to the best of our knowledge, no reports of patients with AN presenting with ischemic stroke have been published, other than a report of the development of IS during refeeding therapy in patients with severe AN.

CASE PRESENTATION

The present case report is aimed at describing the characteristics of an ischemic stroke occurring in a 19-year-old university student who had a 6-month history of AN. She was a non-smoker, had no relevant medical history and no family history of stroke. Upon hospital admission due to symptoms of stroke (aphasia and facial droop), she exhibited severe malnutrition with a BMI of 12.8 kg/m2. Computerized tomography imaging revealed occlusion of the left M2 branch and a congruous extensive area of hypoperfusion. Further investigations ruled out all common causes of stroke: she had no vascular stenosis, no heart diseases or arrhythmias, and no shunts, and gave negative results in autoimmune, toxicological and thrombophilia screenings.

CONCLUSION

Clinicians should suspect development of severe complications, including ischemic stroke, in patients with severe AN. Further extensive group studies or group-based studies are needed to elucidate the etiology of ischemic stroke in patients with severe AN. This will enable us to develop more precise and effective interventions.

Severe and enduring anorexia nervosa and the proposed "Terminal anorexia" category: an expanded meta synthesis

This updated meta-synthesis explores further dimensions of the lived experience of severe and enduring anorexia nervosa (SE-AN) since recent contention regarding proposed "terminal anorexia nervosa (T-AN)". The paper aims to update the original synthesis and to situate participant responses to the category of "T-AN". Thus, extending the proposed conceptualization of the SE-AN experience. A systematic search identified published scholarship (between August 2022 and July 2023), derived from five bibliographic databases. A comprehensive methodology combining Interpretative Phenomenological Analysis and a meta-ethnographic framework enabled the synthesis of meta-themes across 9 new studies. These meta-themes were mapped onto the primary synthesis to further develop upon the earlier LE conceptualization of SE-AN. Nine extracted papers expanded the voices to 447 people within 45 studies. All papers affirmed and enriched the previous themes, and a novel theme was generated from the recent papers. The new theme, "walking on a knife's edge, caught between worlds", informed an expanded conceptualization of SE-AN, termed the Web of Hope. Thus, demonstrating how participants held onto hope in the face of the SE-AN experience. Death, dying and "terminality", were notably absent in the 36 papers in the previous meta-synthesis. Since the proposal of the category of "terminal anorexia" in 2022, studies on the lived experience of SE-AN increasingly focused on how people hold onto hope alongside SE-AN. The findings further drive the field to reflect on therapeutic interventions, labelling and diagnosis, in the face of unknowns, on the premise of "first, do no harm".

Assisted death in eating disorders: a systematic review of cases and clinical rationales

Background

Assisted dying for reasons solely related to an eating disorder (ED) has occurred in multiple countries, including those which restrict the practice to individuals with a terminal condition. The aims of this systematic review were to (1) identify all known cases of assisted deaths among patients with EDs and (2) describe the clinical rationales used to grant patients' requests for assisted death.

Methods

We conducted a systematic search of peer-reviewed studies and publicly available government reports to identify cases of assisted death in patients with EDs. In reports that included qualitative data about the case, clinical rationales were extracted and grouped into domains by qualitative content analysis.

Results

We identified 10 peer-reviewed articles and 20 government reports describing at least 60 patients with EDs who underwent assisted dying between 2012 and 2024. Clinical rationales were categorized into three domains: irremediability, terminality, and voluntary request. Reports emphasized that patients with EDs who underwent assisted death had terminal, incurable, and/or untreatable conditions and had adequate decision-making capacity to make a life-ending decision. Most government reports did not include descriptive-enough data to verify psychiatric conditions.

Conclusion

The results of our systematic review underscore considerable gaps in the reporting of assisted death in patients with psychiatric conditions, posing substantial concerns about oversight and public safety. In many cases, the clinical rationales that were used to affirm patients with EDs were eligible for assisted death lack validity and do not cohere with empirical understanding.

Recent Advances in Cognitive-Behavioural Therapy for Eating Disorders (CBT-ED)

PURPOSE OF REVIEW

Eating disorders require more effective therapies than are currently available. While cognitive behavioural therapy for eating disorders (CBT-ED) has the most evidence to support its effectiveness, it requires substantial improvement in order to enhance its reach and outcomes, and to reduce relapse rates. Recent years have seen a number of noteworthy developments in CBT-ED, which are summarised in this paper.

RECENT FINDINGS

The key advances identified here include: improvements in the efficiency and availability of CBT-ED; expansion of applicability to younger cases across durations of eating disorder; and new methodologies. There have been important recent advances in the field of CBT-ED. However, it is important to stress that there remain gaps in our evidence base and clinical skills, and suggestions are made for future research and clinical directions.

EEG Spatial-temporal Dynamics of Resting-state Activity in Young Women with Anorexia Nervosa: Preliminary Evidence

The aim of this study was to provide preliminary evidence on temporal dynamics of resting-state brain networks in youth with anorexia nervosa (AN) using electroencephalography (EEG). Resting-state EEG data were collected in 18 young women with AN and 18 healthy controls (HC). Between-group differences in brain networks were assessed using microstates analyses. Five microstates were identified across all subjects (A, B, C, D, E). Using a single set of maps representative of the whole dataset, group differences were identified for microstates A, C, and E. A common-for-all template revealed a relatively high degree of consistency in results for reduced time coverage of microstate C, but also an increased presence of microstate class E. AN and HC had different microstate transition probabilities, largely involving microstate A. Using LORETA, for microstate D, we found that those with AN had augmented activations in the left frontal inferior operculum, left insula, and bilateral paracentral lobule, compared with HC. For microstate E, AN had augmented activations in the para-hippocampal gyrus, caudate, pallidum, cerebellum, and cerebellar vermis. Our findings suggest altered microstates in young women with AN associated with integration of sensory and bodily signals, monitoring of internal/external mental states, and self-referential processes. Future research should examine how EEG-derived microstates could be applied to develop diagnostic and prognostic models of AN.

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.

Psychotherapies for eating disorders: findings from a rapid review

BACKGROUND

Psychotherapy is considered central to the effective treatment of eating disorders-focusing on behavioural, psychological, and social factors that contribute to the illness. Research indicates psychotherapeutic interventions out-perform placebo, waitlist, and/or other treatments; but, outcomes vary with room for major improvement. Thus, this review aims to (1) establish and consolidate knowledge on efficacious eating disorder psychotherapies; (2) highlight select emerging psychotherapeutic interventions; and (3) identify knowledge gaps to better inform future treatment research and development.

METHODS

The current review forms part of a series of Rapid Reviews published in a special issue in the Journal of Eating Disorders to inform the development of the Australian-government-funded National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2023, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, and population studies). Data pertaining to psychotherapies for eating disorders were synthesised and outlined in the current paper.

RESULTS

281 studies met inclusion criteria. Behavioural therapies were most commonly studied, with cognitive-behavioural and family-based therapies being the most researched; and thus, having the largest evidence-base for treating anorexia nervosa, bulimia nervosa, and binge eating disorder. Other therapies, such as interpersonal and dialectical behaviour therapies also demonstrated positive treatment outcomes. Emerging evidence supports specific use of Acceptance and Commitment; Integrative Cognitive Affective; Exposure; Mindfulness; and Emotionally-Focused therapies; however further research is needed to determine their efficacy. Similarly, growing support for self-help, group, and computer/internet-based therapeutic modalities was noted. Psychotherapies for avoidant/restrictive food intake disorder; other, and unspecified feeding and eating disorders were lacking evidence.

CONCLUSIONS

Currently, clinical practice is largely supported by research indicating that behavioural and cognitive-behavioural psychotherapies are most effective for the treatment of eating disorders. However, the efficacy of psychotherapeutic interventions varies across studies, highlighting the need for investment and expansion of research into enhanced variants and novel psychotherapies to improve illness outcomes. There is also a pressing need for investigation into the whole range of eating disorder presentations and populations, to determine the most effective interventions.

10‐session Cognitive Behavioural Therapy (CBT-T) for Eating Disorders: A Systematic Review and Narrative Synthesis

To review the literature examining the effectiveness and efficacy of a cognitive behavioural therapy (CBT) for eating disorders delivered in ten sessions for those who are not underweight (CBT-T). A systematic search of the literature (MEDLINE, EMBASE, PsycINFO, Scopus and ProQuest) was conducted to identify relevant publications to date at the time of March 2022 (re-run in May 2023). Intervention studies of any study design that investigated CBT-T offering outcome data at least pre- to post- intervention for eating disorder and related outcomes were included. Results were reported for treatment attrition, abstinence, remission, eating disorder psychopathology, disordered eating behaviours, psychosocial impairment, depression and anxiety and synthesised using a narrative synthesis framework. The Effective Public Health Practice Project (EPHPP) quality assessment tool (Thomas et al., 2004) was used to assess the quality of included studies. Outcomes for 555 people who received CBT-T across eight studies (one randomised control trial and seven non-randomised studies) were synthesised. Support was found for the effectiveness and efficacy of CBT-T for a range of non-underweight eating disorders, with respect to eating disorder psychopathology, disordered eating behaviours, psychosocial impairment, abstinence and remission. CBT-T also led to improvements for depression and anxiety symptoms. CBT-T appears to improve eating disorder and co-morbid outcomes for people with non-underweight eating disorders within ten sessions, with comparable results to standard-length CBT for eating disorders (CBT-ED). Although results for CBT-T are promising, there were concerns with the quality of the studies. Future research is required to strengthen the evidence base with larger, higher-quality studies which compare CBT-T directly with recommended psychological treatments, such as standard-length CBT-ED.

Specific psychological therapies versus other therapies or no treatment for severe and enduring anorexia nervosa

BACKGROUND

Anorexia nervosa is a psychological condition characterised by self-starvation and fear or wait gain or other body image disturbance. The first line of treatment is specific psychological therapy; however, there is no consensus on best practice for treating people who develop severe and enduring anorexia nervosa (SEAN). Notably, there is no universal definition of SEAN.

OBJECTIVES

To evaluate the benefits and harms of specific psychological therapies for severe and enduring anorexia nervosa compared with other specific therapies, non-specific therapies, no treatment/waiting list, antidepressant medication, dietary counselling alone, or treatment as usual.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The last search date was 22 July 2022.

SELECTION CRITERIA

We included parallel randomised controlled trials (RCTs) of people (any age) with anorexia nervosa of at least three years' duration. Eligible experimental interventions were any specific psychological therapy for improved physical and psychological health in anorexia nervosa, conducted in any treatment setting with no restrictions in terms of number of sessions, modality, or duration of therapy. Eligible comparator interventions included any other specific psychological therapy for anorexia nervosa, non-specific psychological therapy for mental health disorders, no treatment or waiting list, antipsychotic treatment (with or without psychological therapy), antidepressant treatment (with or without psychological therapy), dietary counselling, and treatment as usual as defined by the individual trials.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Our primary outcomes were clinical improvement (weight restoration to within the normal weight range for participant sample) and treatment non-completion. Results were presented using the GRADE appraisal tool.

MAIN RESULTS

We found two eligible studies, but only one study provided usable data. This was a parallel-group RCT of 63 adults with SEAN who had an illness duration of at least seven years. The trial compared outpatient cognitive behaviour therapy for SEAN (CBT-SEAN) with specialist supportive clinical management for SEAN (SSCM-SE) over eight months. It is unclear if there is any difference between the effect of CBT-SEAN versus SSCM-SE on clinical improvement at 12 months (risk ratio (RR) 1.42, 95% confidence interval (CI) 0.66 to 3.05) or treatment non-completion (RR 1.72, 95% CI 0.45 to 6.59). There were no reported data on adverse effects. The trial was at high risk of performance and detection bias. We rated the GRADE level of evidence as very low-certainty for both primary outcomes, downgrading for imprecision and risk of bias concerns.

AUTHORS' CONCLUSIONS

This review reports evidence from one trial that evaluated CBT-SEAN versus SSCM-SE. There was very low-certainty evidence of little or no difference in clinical improvement and treatment non-completion between the two therapies. There is a need for larger high-quality trials to determine the benefits of specific psychological therapies for people with SEAN. These should take into account the duration of illness as well as participants' previous experience with evidence-based psychological therapy for anorexia nervosa.

Untreatable or unable to treat? Creating more effective and accessible treatment for long-standing and severe eating disorders

The evidence base for the treatment of severe eating disorders is limited. In addition to improving access to early intervention, there is a need to develop more effective treatments for complex presentations of eating disorders. For patients with long-standing and severe illnesses, particular difficulties might exist with their engagement with treatment and achieving treatment outcomes. Alarmingly, there is an emerging international discourse about a concept labelled as terminal anorexia and about the withdrawal of treatment for people with severe eating disorders, resulting in the death of patients, as a legitimate option. This concept has arisen in the context of vastly overstretched specialist services and insufficient research and funding for new treatments. This Personal View combines multiple perspectives from carers, patients, and mental health professionals based in the UK, highlighting how the risks of current service provision are best alleviated by increasing resources, capacity, and training, and not by a narrowing of the criteria according to which patients with eating disorders are offered the care and support they need.

Bridging cognitive, phenomenological and psychodynamic approaches to eating disorders

Cognitive, psychodynamic, and phenomenological scholars converged their attention on abnormal bodily phenomena as the core psychopathological feature of eating disorders (EDs). While cognitive approaches focus their attention on a need for "objective" (i.e., observable, measurable) variables (including behaviours and distorted cognitions), the phenomenological exploration typically targets descriptions of persons' lived experience. According to a new emerging phenomenological perspective, the classic behavioural and cognitive symptoms of EDs should be considered as epiphenomena of a deeper core represented by a disorder of the embodiment. The cognitive-behavioural model is the most studied and, up till now, clinically efficacious treatment for EDs. However, as any coherent and scientifically grounded model, it presents some limitations in its application. Numerous patients report a chronic course, do not respond to treatment and develop a personality structure based on pathological eating behaviours, since "being anorexic" becomes a new identity for the person. Furthermore, the etiopathogenetic trajectory of EDs influences the treatment response: for example, patients reporting childhood abuse or maltreatment respond differently to cognitive-behavioural therapy. To obtain a deeper comprehension of these disorders, it seems important to shift attention from abnormal eating behaviours to more complex and subtle psycho(patho)logical features, especially experiential ones. This characterisation represents the unavoidable premise for the identification of new therapeutic targets and consequently for an improvement of the outcome of these severe disorders. Thus, the present review aims to provide an integrated view of cognitive, psychodynamic, and phenomenological perspectives on EDs, suggesting new therapeutic targets and intervention strategies based on this integrated model. Level of Evidence: Level V.Level of evidence Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

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.

Integrated enhanced cognitive behavioural (I-CBTE) therapy significantly improves effectiveness of inpatient treatment of anorexia nervosa in real life settings

BACKGROUND

Inpatient treatment of anorexia nervosa can be lifesaving but is associated with high rates of relapse and poor outcomes. To address this, the Oxford service has adapted the enhanced cognitive behavioural treatment (CBTE) model, first developed for inpatients in Italy to a UK national health service (NHS) setting. In this study, we compared the outcomes from treatment as usual (TAU), integrated CBTE (I-CBTE), and alternative treatment models in routine UK clinical practice.

METHODS

This is a longitudinal cohort study, using routinely collected data between 2017 and 2020 involving all adults with anorexia nervosa admitted to specialist units from a large geographical area in England covering a total population of 3.5 million. We compared TAU with (1) I-CBTE (13 weeks inpatient CBTE, restoration to a healthy weight, combined with 7 weeks day treatment followed by 20 weeks of outpatient CBTE; (2) standalone inpatient CBTE (due to insufficient resources since the pandemic; and (3) 6-8 weeks admission with partial weight restoration as crisis management. Primary outcome measures (min. 1 year after discharge from hospital) were defined as: (1) good outcome: Body Mass Index (BMI) > 19.5 and no abnormal eating or compensatory behaviours; (2) poor outcome: BMI < 19.5 and/or ongoing eating disorder behaviours; (3) readmission; or (4) deceased. Secondary outcomes were BMI on discharge, and length of stay.

RESULTS

212 patients were admitted to 15 specialist units in the UK depending on bed availability. The mean age was 28.9 (18-60) years, mean admission BMI was 14.1 (10-18.3), 80% were voluntary. At minimum 1-year follow up after discharge, 70% of patients receiving I-CBTE and 29% standalone inpatient CBTE maintained good outcomes, in contrast with < 5% TAU and crisis management admission. Readmission rates of I-CBTE were 14.3% vs ~ 50% (χ² < 0.0001) in the other groups. The main predictors of good outcome were reaching healthy BMI by discharge, I-CBTE and voluntary status. Age, psychiatric comorbidity and length of stay did not predict outcomes. BMI on discharge and length of stay were significantly better in the CBTE groups than in TAU.

CONCLUSIONS

Our main finding is that in a real-life setting, I-CBTE has superior short- and minimum 1 year outcomes as compared with alternative inpatient treatment models. Dissemination of I-CBTE across the care pathway has the potential to transform outcomes of inpatient treatment for this high-risk patient population and reduce personal and societal costs.

The clinical effectiveness and cost-effectiveness of a 'stepping into day treatment' approach versus inpatient treatment as usual for anorexia nervosa in adult specialist eating disorder services (DAISIES trial): a study protocol of a randomised controlled multi-centre open-label parallel group non-inferiority trial

BACKGROUND

Anorexia nervosa (AN) is a serious and disabling mental disorder with a high disease burden. In a proportion of cases, intensive hospital-based treatments, i.e. inpatient or day patient treatment, are required, with day patient treatment often being used as a 'step-down' treatment after a period of inpatient treatment. Demand for such treatment approaches has seen a sharp rise. Despite this, the relative merits of these approaches for patients, their families, and the NHS and wider society are relatively unknown. This paper describes the rationale for, and protocol of, a two-arm multi-centre open-label parallel group non-inferiority randomised controlled trial, evaluating the effectiveness and cost-effectiveness of these two intensive treatments for adults with severe AN: inpatient treatment as usual and a stepped care day patient approach (the combination of day patient treatment with the option of initial inpatient treatment for medical stabilisation). The main aim of this trial is to establish whether, in adults with severe AN, a stepped care day patient approach is non-inferior to inpatient treatment as usual in relation to improving body mass index (BMI) at 12 months post-randomisation.

METHODS

386 patients with a Diagnostic and Statistical Manual 5th edition diagnosis of severe AN or related disorder, with a BMI of ≤16 kg/m2 and in need of intensive treatment will be randomly allocated to either inpatient treatment as usual or a stepped care day patient approach. Patients in both groups will receive treatment until they reach a healthy weight or get as close to this point as possible. Assessments will be conducted at baseline (prior to randomisation), and at 6 and 12 months post-randomisation, with additional monthly symptom monitoring. The primary outcome will be BMI at the 12-month post-randomisation assessment. Other outcomes will include psychosocial adjustment; treatment motivation, expectations and experiences; cost-effectiveness; and carer burden.

DISCUSSION

The results of this study will provide a rigorous evaluation of two intensive treatment approaches which will inform future national and international treatment guidelines and service provision.

Anorexia nervosa: Outpatient treatment and medical management

Anorexia nervosa (AN) is a disabling, costly and potentially deadly illness. Treatment failure and relapse are common after completing treatment, and a substantial proportion of patients develop severe and enduring AN. The time from AN debut to the treatment initiation is normally unreasonably long. Over the past 20 years there has been empirical support for the efficacy of several treatments for AN. Moreover, outpatient treatment with family-based therapy or individual psychotherapy is associated with good outcomes for a substantial proportion of patients. Early intervention improves outcomes and should be a priority for all patients. Outpatient treatment is usually the best format for early intervention, and it has been demonstrated that even patients with severe or extreme AN can be treated as outpatients if they are medically stable. Inpatient care is more disruptive, more costly, and usually has a longer waiting list than does outpatient care. The decision as to whether to proceed with outpatient treatment or to transfer the patient for inpatient therapy may be difficult. The core aim of this opinion review is to provide the knowledge base needed for performing safe outpatient treatment of AN. The scientific essentials for outpatient treatment are described, including how to assess and manage the medical risks of AN and how to decide when transition to inpatient care is indicated. The following aspects are discussed: early intervention, outpatient treatment of AN, including outpatient psychotherapy for severe and extreme AN, how to determine when outpatient treatment is safe, and when transfer to inpatient healthcare is indicated. Emerging treatments, ethical issues and outstanding research questions are also addressed.

Risk, demand, capacity and outcomes in adult specialist eating disorder services in South-East of England before and since COVID-19

AIMS AND METHOD

This is a longitudinal cohort study describing the demand, capacity and outcomes of adult specialist eating disorder in-patient services covering a population of 3.5 million in a South-East England provider collaborative before and since the COVID-19 pandemic, between July 2018 and March 2021.

RESULTS

There were 351 referrals for admission; 97% were female, 95% had a diagnosis of anorexia nervosa and 19% had a body mass index (BMI) <13. Referrals have increased by 21% since the start of pandemic, coinciding with reduced capacity. Waiting times have increased from 33 to 46 days. There were significant differences in outcomes between providers. A novel, integrated enhanced cognitive behaviour theapy treatment model showed a 25% reduction in length of stay and improved BMI on discharge (50% v. 16% BMI >19), compared with traditional eclectic in-patient treatment.

CLINICAL IMPLICATIONS

Integrated enhanced cognitive behaviour theapy reduced length of stay and improved outcomes, and can offer more effective use of healthcare resources.

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.

Patient perspectives on premature termination of eating disorder treatment: a systematic review and qualitative synthesis

BACKGROUND

High rates of premature treatment termination are a well-reported issue in eating disorder treatment, and present a significant barrier for treatment effectiveness and longer term health outcomes of patients with eating disorders. Understanding patient perspectives on this phenomenon is essential in improving treatment completion rates and informing research and intervention development. The aim of this review is to synthesise qualitative literature on patient perspectives of premature termination of eating disorder treatment and to summarise the key issues leading to discontinuation of treatment.

METHODS

A systematic review of 1222 articles was conducted to identify studies using qualitative methods to investigate patient experiences of prematurely terminating eating disorder treatment. Ten articles were included in the review, with thematic synthesis used to analyse the primary research and develop overarching analytical themes.

RESULTS

Conflict around enmeshment of eating disorder with identity, and lack of support with reconstructing a sense of self without the eating disorder; challenges of managing pressures of social and clinical relationships while feeling unheard and misunderstood by both; expectations and disappointments around treatment; and dissatisfaction with progress were key themes behind premature termination of treatment.

CONCLUSIONS

The findings of this review demonstrate the key issues influencing the decision to end treatment early, highlighting the contribution of individual, environmental, and service-level factors. Implications of these factors are discussed and suggestions raised for future research and service development.

Feasibility of guided internet-based cognitive behavioral therapy for patients with anorexia nervosa

OBJECTIVE

The objective of the present study was to investigate the feasibility of guided internet cognitive behavioral therapy (ICBT) for anorexia nervosa.

METHODS

We conducted a prospective single-arm study between January 2020 and March 2021. The intervention was built using videos, web programs, and chat tools. The intervention program was largely based on metacognitive training. Participants performed the self-help program once a week for 12 consecutive weeks. The primary outcome was the global Eating Disorder Examination Questionnaire (EDE-Q) score. Secondary outcomes included clinical symptoms of eating disorders, metacognitive function, body mass index, depression, and generalized anxiety. The main statistical analysis examined whether the EDE-Q score and other outcomes at the end of the intervention differed from the baseline.

RESULTS

Fourteen participants underwent the trial treatment, and 13 completed the intervention. There was a significant reduction in the global EDE-Q score from 3.48 (SD = 1.4) to 2.54 (SD = 1.5, p = 0.02, Cohen's d = 0.75) from baseline to post-intervention. Some EDE-Q subscales and body checking questionnaire scale demonstrated statistically significant improvements, with moderate to large effect sizes. Although there was no significant improvement in body mass index, metacognitive function, or depressive symptoms, there was a significant improvement in the severity of generalized anxiety (M = -4.0, p = 0.01, Cohen's d = 0.95). No adverse events were observed.

DISCUSSION

Our findings suggest that guided ICBT for anorexia nervosa is well accepted by female patients and practical as a telemedicine approach that improves symptoms. In the future, tightly controlled randomized controlled trials should be conducted for efficacy verification.

The role of embodiment in the treatment of patients with anorexia and bulimia nervosa: a 2-year follow-up study proposing an integration between enhanced cognitive behavioural therapy and a phenomenological model of eating disorders

PURPOSE

Recent studies demonstrated that the embodiment disorder represents a core feature of eating disorders (EDs). The aim of this study was to evaluate the role of its variation as a possible mediator of the efficacy of enhanced cognitive behavioural therapy (CBT-E) on classic ED symptomatology, including body uneasiness.

METHODS

73 patients with anorexia nervosa and 68 with bulimia nervosa were treated with a multidisciplinary approach including CBT-E. Psychometric questionnaires were administered at baseline (T0) and after one (T1) and 2 years (T2) to evaluate general and ED-specific psychopathology, body uneasiness and the embodiment disorder. Data regarding diagnostic crossover and remission were also collected.

RESULTS

Longitudinal analysis showed an improvement of all psychopathological dimensions at T1, which remained stable at T2 (p < 0.05). Remission rate at T2 was 44.7%, and diagnostic crossover occurred in 17.0% of patients. Higher levels of embodiment disorder predicted increased diagnostic instability (OR: 1.80 [1.01-3.20], p = 0.045). The amelioration of the embodiment disorder mediated the decrease in both ED-specific psychopathology (indirect effect: 0.67 [0.46-0.92]) and body uneasiness (indirect effect: 0.43 [0.28-0.59]).

CONCLUSION

For the first time, these findings highlighted the role of the embodiment disorder as a maintaining factor of ED symptomatology, supporting the importance of integrating CBT-E with a phenomenological model of EDs.

Recovering Uncertainty: Exploring Eating Disorder Recovery in Context

Attending to the shades of grey in eating disorder recovery may help to illuminate possibilities for navigating recoveries in their full complexity and diversity. There is a need for more complexity and flexibility in understandings of the timelines, processes, endpoints, and versions of eating disorder recoveries. In this article, we explore eating disorder recovery as a dynamic, intercorporeal, and non-linear process. Drawing on interviews with 20 people doing significantly better than they were during a time of acute distress around food and body, we articulate "recoveries" in relation to four themes: Fuzzy Logics of Time, Not Only Recovered, Recovery is Not All Sunshine and Rainbows, and The Life of Recovery. These themes speak to the ways in which participants struggled to articulate the temporalities of their recoveries, situated recovery as one among many events and processes that shaped their being in the world, resisted "too perfect" articulations of recovery journeys/ endpoints, and described preferred versions of and open-ended guidelines for recovery. We argue that eating disorder recoveries are as complicated and messy as lives themselves and are equally entangled in social contexts. We suggest that articulations of recovery be attuned to power dynamics as they operate in dictating which performances of eating disorders and recovery will be honoured as "legitimate" and whose pathways to recovery will be respected.

New developments in cognitive-behavioural therapy for eating disorders (CBT-ED)

PURPOSE OF REVIEW

This review summarizes recent developments in cognitive-behavioural therapy for eating disorders (CBT-ED). More specifically, the past five years were covered, with the latest UK and Dutch guidelines for eating disorders as a starting benchmark, and with special consideration of the past 18 months.

RECENT FINDINGS

The new research can be divided into findings that have: (1) reinforced our existing understanding of CBT-ED's models and impact; (2) advanced our understanding and the utility of CBT-ED, including its application for the 'new' disorder Avoidant/Restrictive Food Intake Disorder (ARFID); (3) suggested new directions, which require further exploration in clinical and research terms. These include learning from the circumstances of the COVID-19 pandemic.

SUMMARY

CBT-ED has developed substantially in the past 5 years, with consolidation of its existing evidence base, further support for real-life implementation, extension of methods used, and the development of new approaches for working with younger people - particularly in the form of treatments for ARFID. Over the past 18 months, even more promising changes in delivery occurred in response to the COVID19 pandemic, showing that we can adapt our methods in order to work effectively via remote means. Challenges remain regarding poor outcomes for anorexia nervosa.

Change in eating-disorder psychopathology network structure in patients with anorexia nervosa treated with intensive cognitive behavior therapy

OBJECTIVE

This study was designed to compare the change in eating-disorder feature networks in patients with anorexia nervosa after treatment with intensive enhanced cognitive behavior therapy (CBT-E).

METHODS

Patients seeking treatment for anorexia nervosa were consecutively recruited from January 2016 to September 2020. All patients aged ≥16 years who completed a 20-week intensive CBT-E program (13 weeks of inpatient followed by 7 weeks of day-hospital treatment) were included in the study. Body mass index (BMI) was measured, and the Eating Disorder Examination Questionnaire completed for each patient, both at baseline and the end of treatment.

RESULTS

The sample comprised 214 patients with anorexia nervosa. Treated patients showed significant improvements in BMI and eating-disorder psychopathology. Network analysis revealed a significant reduction in the network global and connection strengths at the end of treatment. The most central and highly interconnected nodes in the network at baseline were related to the drive for thinness, but at the end of treatment to body image concerns. Some edge connections were significantly stronger at baseline than at the end of treatment, while others were significantly stronger at the end of treatment than at baseline.

DISCUSSION

CBT-E reduces the psychopathology network connectivity over time in patients with anorexia nervosa. The differences in central nodes and edge connections between baseline and end of treatment, not detected by classical inferential analysis, may be informative for understanding the centrality of symptoms in the psychopathology network, and how a specific treatment may act to reduce symptoms and change their connections over time.

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.

The Ethical Defensibility of Harm Reduction and Eating Disorders

Eating disorders are mental illnesses that can have a significant and persistent physical impact, especially for those who are not treated early in their disease trajectory. Although many persons with eating disorders may make a full recovery, some may not; this is especially the case when it comes to persons with severe and enduring anorexia nervosa (SEAN), namely, those who have had anorexia for between 6 and 12 years or more. Given that persons with SEAN are less likely to make a full recovery, a different treatment philosophy might be ethically warranted. One potential yet scarcely considered way to treat persons with SEAN is that of a harm reduction approach. A harm reduction philosophy is deemed widely defensible in certain contexts (e.g. in the substance use and addictions domain), and in this paper we argue that it may be similarly ethically defensible for treating persons with SEAN in some circumstances.

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.

Discharge Body Mass Index, Not Illness Chronicity, Predicts 6-Month Weight Outcome in Patients Hospitalized With Anorexia Nervosa

Proposed treatments for severe and enduring anorexia nervosa (SE-AN) focus on quality of life, and psychological and social functioning. By de-emphasizing weight restoration as a priority, however, premature diagnosis of SE-AN may reduce potential for recovery. The present study assessed the effect of weight restoration, illness duration, and severity on treatment outcome 6 months after discharge from an intensive, meal-based behavioral treatment program. Participants included hospitalized adult women (N = 191) with AN or underweight other specified feeding and eating disorder (OSFED). Participants were characterized as short-term (ill <7 years; n = 74) or long-term ill (ill ≥ 7 years; n = 117). Compared with short-term ill, long-term ill patients were older, had lower lifetime body mass index (BMI), more prior admissions, and exhibited greater depression and neuroticism. Long-term vs. short-term ill patients gained weight at the same rate (~2 kg/wk) and were equally likely to be weight restored by discharge (>75% reached BMI ≥ 19 kg/m² in both groups). At 6-month follow-up (n = 99), both groups had equivalent self-reported BMI, and depression, drive for thinness, body dissatisfaction, and bulimia scores. The only predictor of BMI ≥ 19 kg/m² at follow-up was discharge BMI. The likelihood of a BMI ≥ 19 kg/m² at follow-up was 5-fold higher for those with discharge BMI ≥ 19 kg/m². Few studies of long-term ill inpatients with AN have examined the impact of full weight restoration on short-term outcomes. This study supports the therapeutically optimistic stance that, regardless of illness duration, hospitalized patients with AN benefit from gaining weight to a BMI ≥ 19 kg/m².

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.

Effectiveness of intensive cognitive behavioral therapy in adolescents and adults with anorexia nervosa

OBJECTIVE

This study aimed to compare the effectiveness of an intensive treatment based on enhanced cognitive behavioral therapy (CBT-E) in adolescent and adult patients with anorexia nervosa.

METHODS

A total of 150 consecutive patients (74 adolescents and 81 adults) were admitted to a 20-week intensive CBT-E program (13 weeks of inpatient followed by 7 weeks of day-hospital treatment). All patients had responded poorly to previous outpatient treatments and were assessed at admission, end of treatment (EOT), and 20- and 60-week follow-ups.

RESULTS

About 70% of eligible patients began the program, and more than 85% completed it. Body mass index (BMI) in adults and BMI-for-age percentile in adolescents improved significantly from baseline to EOT, remained stable until 20-week follow-up, and slightly decreased from 20-week follow-up to 60-week follow-up, while remaining in the lower normal range. Eating disorder psychopathology, general psychopathology, and clinical impairment scores decreased significantly at EOT and showed only a slight increase from EOT to follow-ups. No difference was found between adolescent and adult patients in treatment acceptance, dropout, or any outcome measure.

DISCUSSION

These findings indicate that intensive CBT-E seems to be an effective treatment for severely ill adolescent and adult patients with anorexia nervosa.

Severe and enduring anorexia nervosa: No easy solutions

There is currently no evidence-based definition of severe and enduring anorexia nervosa (SE-AN) with which to reliably inform clinical practice and research. Indeed, data on the effect of AN severity and duration on treatment outcome are inconsistent. A large group of patients with SE-AN are repeatedly unsuccessfully managed with the available eating disorders treatments and have no access to adequate treatment for their illness. Cognitive behavioral therapy (CBT) adapted for SE-AN has been designed to enhance quality of life and reduce harm rather than promoting weight gain in such patients, and has had some success. However, a percentage of patients with SE-AN achieves remission, or at least returns to a normal weight range, with available evidence-based treatments for eating disorders, such as enhanced CBT (CBT-E). It would therefore be worth conducting a large-scale randomized controlled trial comparing CBT adapted for SE-AN with CBT-E to assess their relative acceptability; efficacy, including their effect on quality of life and medical stability; cost-effectiveness; and the treatment response moderators that might allow better matching of patients with SE-AN to a treatment oriented either to harm reduction or to change.

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.

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

BACKGROUND

We explored the utility of "staging" anorexia nervosa (AN) by duration of illness and psychological wellbeing. We also investigated 12-month symptom trajectories and service usage in a large cohort of patients with AN assessed for outpatient treatment.

METHOD

We conducted secondary analyses on data from a multisite clinical trial of adults with AN (n = 187) recruited from 22 NHS England specialist eating disorder (ED) services into a digital treatment augmentation study. Clinical outcomes and service use were measured at postintervention (six weeks), 6 and 12 months. We grouped patients into two categories: "early stage" (illness duration <3 years; n = 60) and "severe and enduring" stage (SE-AN; n = 41) indicated by distress (Depression Anxiety and Stress Scales, DASS ≥60) and illness duration (≥7 years).

RESULTS

At 12 months, patients reported large improvements in body mass index, small to moderate improvements in ED symptoms, mood, and work/social adjustment, and 23.6% met criteria for recovery. However, patients classified as SE-AN reported higher rates of accessing intensive services, higher ED symptomatology, and poorer work/social adjustment at baseline, and lower rates of improvement in work/social adjustment at 12 months compared to "early stage" respondents.

DISCUSSION

Although present findings suggest overall symptomatic improvements, exploratory results highlight marked differences in course and service use between people at different stages of AN, suggesting a need to consider staging for clinical decision-making. Further research differentiating between clinical subtypes of AN and adoption of a more personalized approach may ensure that services and care pathways better fit patient needs.

Executive functioning and spatial processing in anorexia nervosa: an experimental study and its significance for the allocentric lock theory

PURPOSE

The allocentric lock theory (ALT) suggests that people with eating disorders have difficulties in multisensory integration in two reference frames-egocentric and allocentric, whereby the egocentric, but not allocentric, is impaired. This leads to a distorted body image that contributes to the development and maintenance of the disorder. The current study aimed to explore a facet of the ALT, namely, the visuo-spatial aspect, and its relation to cognitive flexibility in patients with anorexia nervosa (AN).

METHODS

Fifty-five participants took part in the study: 20 AN patients and 35 controls, matched by age and education. The object perspective taking test (OPTT) and the mental rotation test (MRT), tapping egocentric and allocentric representations, respectively, and a set-shifting task were administered. The brief symptom inventory was used to measure overall levels of distress.

RESULTS

AN patients showed higher level of distress. They performed poorer on the OPTT and set-shifting task but not on the MRT. The OPTT and MRT were correlated for controls but not for AN patients, while the set-shifting task and body mass index were associated with the OPTT but not with the MRT for the AN patients.

CONCLUSIONS

The findings support the ALT by demonstrating impaired visual egocentric representations and intact allocentric visual functions in AN patients, with cognitive flexibility associated only with the egocentric frame. Therefore, egocentric frame impairment in AN patients may be influenced by visual perception and cognitive flexibility deficiency.

Treatment interventions for Severe and Enduring Eating Disorders: Systematic review

OBJECTIVE

Approximately 20% of people with Anorexia Nervosa (AN) and 10% with Bulimia Nervosa (BN) will eventually develop a long-standing illness. Although there is no set definition for Severe and Enduring eating Disorder (SE-ED), the common criteria relate to a long duration of the disorder and a number of unsuccessful treatment attempts. Research evidence for treatment of SE-ED remains limited, thus the objective of this systematic review was to describe different treatment interventions and their effects on SE-ED-related outcomes.

METHOD

A systematic search for quantitative treatment studies of adult participants with SE-ED was conducted in June 2019 (PROSPERO, CRD42018115802) with no restriction on eating disorder type. Altogether, 2,938 studies were included for title and abstract screening.

RESULTS

After systematic searches and article screening, 23 studies (3 randomized controlled trials, 3 open-label studies, 8 naturalistic follow-up studies, 8 case series and case studies, and 1 partially blinded pilot study) were included in the analysis and data extraction. Methodological quality of the included studies was generally low. Inpatient treatment programs (n = 5) were effective in short-term symptom reduction, but long-term results were inconsistent. Outpatient and day-hospital treatment programs (n = 5) seemed promising for symptom reduction. Drug interventions (n = 5) showed some benefits, especially as adjuvant therapies. Brain stimulation (n = 6) led to improvements in depressive symptoms. Other treatments (n = 2) produced mixed results.

DISCUSSION

This is the first systematic review to examine all of the different treatment interventions that have been studied in SE-ED. The results will inform future interventions in research and clinical practice.

A systematic review of enhanced cognitive behavioral therapy (CBT-E) for eating disorders

OBJECTIVE

To review the literature examining the efficacy and effectiveness of enhanced cognitive behavioral therapy (CBT-E) for adults and older adolescents with eating disorders.

METHOD

A systematic search of the literature (using PsycINFO and PubMed) was conducted in order to identify relevant publications (randomized controlled trials [RCTs] and uncontrolled trials) up to June 2019. Effect sizes were reported for outcomes including treatment attrition and remission rates, eating disorder behaviors, body mass index (BMI), and core eating disorder psychopathology. The Downs and Black checklist was used to assess the quality of included studies.

RESULTS

Twenty studies (10 RCTs and 10 uncontrolled trials) met criteria for inclusion. Support was found for the efficacy and effectiveness of CBT-E for the full spectrum of eating disorders, with respect to reducing eating disorder behaviors and core psychopathology. BMI also increased, with large effects, for individuals with AN. However, the majority of the randomized trials included in this review did not demonstrate superiority of CBT-E over comparison treatments, particularly in the longer-term. Furthermore, rates of attrition and remission for CBT-E among individuals without AN did not appear to differ from rates for CBT-BN.

DISCUSSION

There is evidence to support CBT-E as an efficacious and effective treatment for adults and older adolescents with a range of eating disorder diagnoses. Future research would benefit from directly comparing CBT-E to CBT-BN, expanding measured outcomes to include driven exercise and subjective binge eating, increasing consistency in the definition and measurement of outcomes, and exploring factors associated with treatment retention.

Physical and psychological aspects of anorexia nervosa based on duration of illness: a cross-sectional study

Background

We evaluated physical and psychological features of patients with anorexia nervosa (AN) who differed by duration of illness.

Methods

Data were obtained from 204 female patients with AN, divided into two groups based on illness duration: short-term illness duration (less than 5 years; n = 118); and long-term duration (5 years or more; n = 86). Physical parameters were measured using blood serum testing and psychological aspects were assessed using various instruments.

Results

A significantly higher proportion of restricting type AN was observed in the short-term group while the proportion of binge eating/purging type AN was higher in the long-term group. There was no difference in body mass index (BMI) between the groups. Serum total protein, albumin, potassium, chloride, and calcium in the long-term group were significantly lower than in the short-term group. Overall scores on the Eating Disorder Inventory as well as most of the subscales, except maturity fears, were higher in the long-term group than in the short-term group. The care subscale of the Parental Bonding Instrument (PBI) was lower in the long-term group than in the short-term group, while the overprotection subscale of the PBI was higher in the long-term group than in the short-term group. Results of a multiple regression analysis indicated that the overprotection subscale of the PBI was the only significant predictor of duration of illness.

Conclusions

Duration of illness may be associated with physical and psychological features of AN; thus, adapting therapeutic approaches to illness duration might be necessary.

Optimizing treatment outcomes in adolescents with eating disorders: The potential role of cognitive behavioral therapy

OBJECTIVE

While family-based treatment (FBT) is the leading psychological therapy for adolescents with eating disorders, it is not universally effective or suitable. This study considered the effectiveness of cognitive-behavioral therapy for eating disorders (CBT-ED) in adolescent cases where FBT was not fully effective or where it was not applicable to the individual case.

METHOD

A transdiagnostic case series of 54 adolescents with eating disorders (52% with anorexia nervosa; 31% with atypical anorexia nervosa) were offered CBT-ED following previous treatment using FBT or following FBT being judged inappropriate. Pre-post outcomes were assessed using standardized measures of eating attitudes and clinical impairment, and weight change was measured for the patients with anorexia nervosa.

RESULTS

The rate of attrition was similar to that found in other CBT-ED studies (38.9% of patients who started CBT-ED; 59.3% of those offered CBT-ED). The patients showed positive outcomes on all measures, regardless of whether they had previously been treated with FBT. Effect sizes were moderate to large. Severity and duration of the eating disorder were unrelated to outcomes.

DISCUSSION

CBT-ED merits consideration as a second-line approach for adolescents with eating disorders when FBT has not been effective or could not be applied. There is no evidence that previous failure to benefit from FBT impairs outcome from subsequent CBT-ED, and severity and duration of the eating disorder did not influence outcome. Treatment matching for adolescents with eating disorders might consider the role of previous treatment outcomes and family availability in determining optimum treatment strategies for individuals.
