Valuing the voice of lived experience of eating disorders in the research process: Benefits and considerations

Adaptive design trials in eating disorder research: A scoping review

OBJECTIVE

This scoping review sought to map the breadth of literature on the use of adaptive design trials in eating disorder research.

METHOD

A systematic literature search was conducted in Medline, Scopus, PsycInfo, Emcare, Econlit, CINAHL and ProQuest Dissertations and Theses. Articles were included if they reported on an intervention targeting any type of eating disorder (including anorexia nervosa, bulimia nervosa, binge-eating disorder, and other specified feeding or eating disorders), and employed the use of an adaptive design trial to evaluate the intervention. Two independent reviewers screened citations for inclusion, and data abstraction was performed by one reviewer and verified by a second.

RESULTS

We identified five adaptive design trials targeting anorexia nervosa, bulimia nervosa and binge-eating disorder conducted in the USA and Australia. All employed adaptive treatment arm switching based on early response to treatment and identified a priori stopping rules. None of the studies included value of information analysis to guide adaptive design decisions and none included lived experience perspectives.

DISCUSSION

The limited use of adaptive designs in eating disorder trials represents a missed opportunity to improve enrolment targets, attrition rates, treatment outcomes and trial efficiency. We outline the range of adaptive methodologies, how they could be applied to eating disorder research, and the specific operational and statistical considerations relevant to adaptive design trials.

PUBLIC SIGNIFICANCE

Adaptive design trials are increasingly employed as flexible, efficient alternatives to fixed trial designs, but they are not often used in eating disorder research. This first scoping review identified five adaptive design trials targeting anorexia nervosa, bulimia nervosa and binge-eating disorder that employed treatment arm switching adaptive methodology. We make recommendations on the use of adaptive design trials for future eating disorder trials.

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

OBJECTIVE

This novel study sought to understand lived experience and carer perspectives on the use of adaptive trials to evaluate interventions for eating disorders, in addition to understanding the factors and outcomes of most importance in eating disorder research and treatments from a lived experience perspective.

METHOD

A total of 73 people with either lived or carer experience consented, 70 started the questionnaire, and 36 (51%) completed all questions. Participants were asked Likert scale and open-ended questions to understand what factors and outcomes of eating disorder interventions were most important to them and understand their pre-existing knowledge of clinical trials. Two videos were then used to explain randomized controlled trials (RCTs) and adaptive trials and participants were asked their opinions, including perceived benefits and concerns, of each trial type.

RESULTS

The thematic analysis found two key themes regarding factors important in eating disorder treatment: Person-centred care and Evidence-based and effective treatment; and two key themes regarding outcomes of treatment: Sustained, full recovery and The bigger picture. Both RCTs and adaptive trials were viewed favorably, however, there was a slight preference for adaptive trials. Key themes for both demonstrated perceived benefits and ethical, practical, and scientific considerations unique to each.

DISCUSSION

Findings demonstrate the support of adaptive trials in eating disorder interventions from people with lived experience and their carers. It is recommended that researchers consider the use of adaptive designs and the incorporation of lived experience perspectives when designing future intervention trials.

PUBLIC SIGNIFICANCE

This novel study found that the use of adaptive trials in eating disorder intervention research is supported by people with lived experience and carers. Furthermore, the factors and outcomes of most importance to participants in this study are comparable to those previously identified in the emerging literature. The use of adaptive designs and the incorporation of lived experience are recommended in further clinical trials.

Improving motivation and treatment uptake behaviors of patients with eating disorders using patient narrative videos: study protocol of a pilot randomized controlled trial

BACKGROUND

Patients with eating disorders (ED) typically report delays between the onset of symptoms and engagement with treatment services. Personal barriers including stigma, shame, and guilt, as well as the availability of social support may influence patients' decisions to engage with treatment services. Patient narratives are personalized stories discussing the illness and recovery of previously affected persons. Such narratives can reduce self-stigma and provide current patients with hope for their own recovery.

METHOD

This pilot study will examine the effects of patient narrative videos on the treatment motivation and uptake of treatment services for patients with ED. Three narrative videos were developed from the perspectives of (a) a former patient with an ED, (b) an ED specialist, and (c) the same former patient discussing a somatic condition unrelated to ED. Patients will be randomized into three video viewing and one treatment-as-usual group. Effects on treatment motivation will be assessed using the University of Rhode Island Change Assessment Scale (URICA-S) immediately after viewing the videos, as well as one-week and three-month follow-ups. Treatment uptake will be assessed during follow-up using a questionnaire listing possible treatment interactions. A post-intervention questionnaire and semi-structured interviews will be used to assess the feasibility and acceptability of patient narrative videos for this population.

DISCUSSION

There is an urgent need to encourage patients with ED to engage with specialized treatments as soon as possible. Patient narratives may be a pivotal approach to implementing cost effective and easy to disseminate early intervention programs to future patients with ED.

"I Need Someone to Help Me Build Up My Strength": A Meta-Synthesis of Lived Experience Perspectives on the Role and Value of a Dietitian in Eating Disorder Treatment

Dietitians are included in eating disorder (ED) treatment teams for their expertise in nutrition. However, little is known about an individual's experience of dietetic intervention as part of their ED treatment and what they value as part of dietetic care. Therefore, the aim of this review was to synthesise the available qualitative literature to understand the role and value of a dietitian in ED treatment from the perspective of individuals with lived experience. Six databases and Google Scholar were searched and a thematic synthesis and meta-synthesis of fifteen studies were conducted. Four themes were constructed from the data: (1) "guidance and structure"-Provision of nutrition knowledge and skills; (2) "having all my bases covered"-Dietitians as part of a multidisciplinary team; (3) Challenges in nutritional treatment; and (4) "it was my treatment and my recovery"-Person-centred dietetic treatment. Across all identified themes was the cross-cutting theme of a shared treatment journey between the dietitian and the individual receiving treatment. These findings support dietitians having a role that is not limited only to the provision of nutrition treatment in ED care and illustrates the importance of dietitians engaging with clients by centring on the individual's needs and preferences. Further understanding helpful dietetic treatment components and identifying gaps in training is needed to develop these broader roles for dietetic care.

Co-producing principles to guide health research: an illustrative case study from an eating disorder research clinic

BACKGROUND

There is significant value in co-produced health research, however power-imbalances within research teams can pose a barrier to people with lived experience of an illness determining the direction of research in that area. This is especially true in eating disorder research, where the inclusion of co-production approaches lags other research areas. Appealing to principles or values can serve to ground collaborative working. Despite this, there has not been any prior attempt to co-produce principles to guide the work of a research group and serve as a basis for developing future projects.

METHODS

The aim of this piece of work was to co-produce a set of principles to guide the conduct of research within our lived experience led research clinic, and to offer an illustrative case for the value of this as a novel co-production methodology. A lived experience panel were recruited to our eating disorder research group. Through an iterative series of workshops with the members of our research clinic (composed of a lived experience panel, clinicians, and researchers) we developed a set of principles which we agreed were important in ensuring both the direction of our research, and the way in which we wanted to work together.

RESULTS

Six key principles were developed using this process. They were that research should aim to be: 1) real world-offering a clear and concrete benefit to people with eating disorders, 2) tailored-suitable for marginalised groups and people with atypical diagnoses, 3) hopeful-ensuring that hope for recovery was centred in treatment, 4) experiential-privileging the 'voice' of people with eating disorders, 5) broad-encompassing non-standard therapeutic treatments and 6) democratic-co-produced by people with lived experience of eating disorders.

CONCLUSIONS

We reflect on some of the positives as well as limitations of the process, highlighting the importance of adequate funding for longer-term co-production approaches to be taken, and issues around ensuring representation of minority groups. We hope that other health research groups will see the value in co-producing principles to guide research in their own fields, and will adapt, develop, and refine this novel methodology.

Enriching a randomized controlled treatment trial for anorexia nervosa by lived experience-Chances and effects of a lived experience council in the SUSTAIN study

BACKGROUND

The development and advancement of treatment and care options is one priority in the field of eating disorders. The inclusion of persons with lived experience with eating disorders into clinical research could enrich and accelerate this endeavor, as they can add different perspectives on the disease and its treatment. Although lived experience perspectives are increasingly part of eating disorder research, they have not been widely or structurally implemented into clinical trials and there is limited information on the practice of participatory research, its framework and consequences.

AIMS

The present work outlines the participatory collaboration with a lived experience council in the randomized controlled treatment trial SUSTAIN.

MATERIALS & METHODS

The manuscript is a participatory publication co-written by individuals with lived experience with anorexia nervosa and eating disorder researchers.

RESULTS

We report on motivations for this approach, our collaboration principles, structures and shared experience of working together in the trial, the potential burdens and benefits related to participation for people with lived experience.

DISCUSSION

We outline future directions and perspectives to integrate a participatory framework into clinical eating disorder research.

CONCLUSION

The involvement of people with experiential knowledge is complex, but possible in clinical research on ED and bears huge potential for the development of more effective care.

PUBLIC SIGNIFICANCE

Incorporating perspectives of people with lived experience into a participatory framework of mental health research bears huge potential on a societal level. This includes more relevant research topics and designs, more tailored and effective interventions, and facilitated implementation, as well as dissemination, higher credibility, destigmatization of mental illness, and patient empowerment. Participatory clinical research, however, needs structural anchorage within science and society.

Experiences of inpatient eating disorder admissions: A systematic review and meta-synthesis

OBJECTIVE

There has been a significant increase in the number of inpatient admissions for individuals with eating disorders and, with the most critical cases requiring inpatient treatment, it is essential that we continue to improve associated outcomes. The aim of the study was to synthesise the available qualitative literature on the experiences of inpatient admissions for eating disorders to understand individuals' experiences and identify areas that may require further research and/or service development.

METHOD

Searches were performed on the following online databases: PsycINFO, PsycArticles, PsycTherapy MEDLINE, Embase, CINAHL, ASSIA, Scopus and Proquest Open Access Theses. Only papers with qualitative data regarding individuals' experiences of inpatient eating disorder treatment were considered. The CASP qualitative checklist was used to assess studies and relevant data items were extracted. Thematic synthesis was used to integrate the findings in the identified studies. GRADE-CERQual was used to rate the confidence in the findings.

RESULTS

Twenty-eight studies were identified which the CASP assessment considered to be adequate. The synthesis produced 5 main themes; 'Care and control', 'Inpatient bubble', 'Being supported and understood', 'Challenges of living with others' eating disorders' and finally 'Relationship to eating disorder'. The GRADE CERQual framework rated findings with high or moderate confidence.

CONCLUSIONS

Findings reaffirmed the importance of patient-centred care and the significant impact of being separated from normal life with others also experiencing an eating disorder.

"It's not about wanting to be thin or look small, it's about the way it feels": an IPA analysis of social and sensory differences in autistic and non-autistic individuals with anorexia and their parents

BACKGROUND

Despite increasing evidence to support an overlap between autism and anorexia nervosa (AN), underlying mechanisms remain poorly understood. Social and sensory factors have emerged as promising targets in both autism and AN, however there remains scope to compare these differences across autistic and non-autistic experiences of AN. Drawing on dyadic multi-perspectives, this study explored experiences of social and sensory differences in autistic and non-autistic adults and their parents and/or carers.

METHODS

Using interpretative phenomenological analysis (IPA), dyadic interviews were conducted with 14 dyads, with seven autistic dyads and seven non-autistic dyads. Data analysis was subjected to a triangulation of interpretations: (1) the participants themselves; (2) a neurotypical researcher; (3) and an Autistic researcher with lived/living experience of AN.

RESULTS

IPA identified three themes in each group, with similarities and differences between autistic and non-autistic dyads. Similar themes were identified regarding the importance of social connectedness and socio-emotional difficulties, as well a common lack of trust in the social and sensory self and body. Autism-specific themes centred on feelings of social 'defectiveness', disparities between sensing and expressing certain cues, and lifelong, multi-sensory processing differences. Non-autistic themes reflected social comparisons and inadequacy, and sensitivities to the learning of ideals and behaviour through early experiences.

CONCLUSIONS

While similarities were observed across both groups, there appeared to be notable differences in the perceived role and influence of social and sensory differences. These findings may have important implications on the delivery and modification of eating disorder interventions. Specifically, they suggest that while treatment targets may look similar, subtle differences in underlying mechanisms and approaches may be required for Autistic individuals with AN across sensory, emotion and communication-based interventions.

Eating disorder outcomes: findings from a rapid review of over a decade of research

BACKGROUND

Eating disorders (ED), especially Anorexia Nervosa (AN), are internationally reported to have amongst the highest mortality and suicide rates in mental health. With limited evidence for current pharmacological and/or psychological treatments, there is a grave responsibility within health research to better understand outcomes for people with a lived experience of ED, factors and interventions that may reduce the detrimental impact of illness and to optimise recovery. This paper aims to synthesise the literature on outcomes for people with ED, including rates of remission, recovery and relapse, diagnostic crossover, and mortality.

METHODS

This paper forms part of a Rapid Review series scoping the evidence for the field of ED, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/MEDLINE were searched for studies published between 2009 and 2022 in English. High-level evidence such as meta-analyses, large population studies and Randomised Controlled Trials were prioritised through purposive sampling. Data from selected studies relating to outcomes for people with ED were synthesised and are disseminated in the current review.

RESULTS

Of the over 1320 studies included in the Rapid Review, the proportion of articles focused on outcomes in ED was relatively small, under 9%. Most evidence was focused on the diagnostic categories of AN, Bulimia Nervosa and Binge Eating Disorder, with limited outcome studies in other ED diagnostic groups. Factors such as age at presentation, gender, quality of life, the presence of co-occurring psychiatric and/or medical conditions, engagement in treatment and access to relapse prevention programs were associated with outcomes across diagnoses, including mortality rates.

CONCLUSION

Results are difficult to interpret due to inconsistent study definitions of remission, recovery and relapse, lack of longer-term follow-up and the potential for diagnostic crossover. Overall, there is evidence of low rates of remission and high risk of mortality, despite evidence-based treatments, especially for AN. It is strongly recommended that research in long-term outcomes, and the factors that influence better outcomes, using more consistent variables and methodologies, is prioritised for people with ED.

The integrated treatment of eating disorders, posttraumatic stress disorder, and psychiatric comorbidity: a commentary on the evolution of principles and guidelines

Psychiatric comorbidity is the norm in the assessment and treatment of eating disorders (EDs), and traumatic events and lifetime PTSD are often major drivers of these challenging complexities. Given that trauma, PTSD, and psychiatric comorbidity significantly influence ED outcomes, it is imperative that these problems be appropriately addressed in ED practice guidelines. The presence of associated psychiatric comorbidity is noted in some but not all sets of existing guidelines, but they mostly do little to address the problem other than referring to independent guidelines for other disorders. This disconnect perpetuates a "silo effect," in which each set of guidelines do not address the complexity of the other comorbidities. Although there are several published practice guidelines for the treatment of EDs, and likewise, there are several published practice guidelines for the treatment of PTSD, none of them specifically address ED + PTSD. The result is a lack of integration between ED and PTSD treatment providers, which often leads to fragmented, incomplete, uncoordinated and ineffective care of severely ill patients with ED + PTSD. This situation can inadvertently promote chronicity and multimorbidity and may be particularly relevant for patients treated in higher levels of care, where prevalence rates of concurrent PTSD reach as high as 50% with many more having subthreshold PTSD. Although there has been some progress in the recognition and treatment of ED + PTSD, recommendations for treating this common comorbidity remain undeveloped, particularly when there are other co-occurring psychiatric disorders, such as mood, anxiety, dissociative, substance use, impulse control, obsessive-compulsive, attention-deficit hyperactivity, and personality disorders, all of which may also be trauma-related. In this commentary, guidelines for assessing and treating patients with ED + PTSD and related comorbidity are critically reviewed. An integrated set of principles used in treatment planning of PTSD and trauma-related disorders is recommended in the context of intensive ED therapy. These principles and strategies are borrowed from several relevant evidence-based approaches. Evidence suggests that continuing with traditional single-disorder focused, sequential treatment models that do not prioritize integrated, trauma-focused treatment approaches are short-sighted and often inadvertently perpetuate this dangerous multimorbidity. Future ED practice guidelines would do well to address concurrent illness in more depth.

More than an outcome: a person-centered, ecological framework for eating disorder recovery

BACKGROUND

Eating disorder recovery is a complex phenomenon. While historical understandings focused on weight and behaviours, the importance of psychological factors is now widely recognized. It is also generally accepted that recovery is a non-linear process and is impacted by external factors. Recent research suggests a significant impact of systems of oppression, though these have not yet been named in models of recovery. BODY: In this paper, we propose a research-informed, person-centered, and ecological framework of recovery. We suggest that there are two foundational tenets of recovery which apply broadly across experiences: recovery is non-linear and ongoing and there is no one way to do recovery. In the context of these tenets, our framework considers individual changes in recovery as determined by and dependent on external/personal factors and broader systems of privilege. Recovery cannot be determined by looking solely at an individual's level of functioning; one must also consider the broader context of their life in which changes are being made. To conclude, we describe the applicability of the proposed framework and offer practical considerations for incorporating this framework in research, clinical, and advocacy settings.

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.

The effectiveness of lived experience involvement in eating disorder treatment: A systematic review

OBJECTIVE

This systematic review sought to understand the effectiveness of lived experience mentoring, by people recovered from an eating disorder, with clinical samples currently receiving eating disorder treatment.

METHODS

The systematic review was conducted using PsycINFO, MEDLINE, Scopus, and ProQuest Dissertations and Theses Global and reviewing reference lists of included papers. Articles were included if they: (1) were intervention studies that included peer (recovered from an eating disorder) involvement, (2) delivered the intervention to clinical samples (or carers with direct involvement in treatment), (3) were in English, and (4) included quantitative results.

RESULTS

Eleven studies were included across randomized control trials (RCTs), case series, and a case study; there was variation in quality. Findings varied considerably with some concluding that lived experience mentoring led to significant improvements for mentees, while other studies found no significant differences. Mentor outcomes were often not evaluated. Of those that did assess mentors, there is preliminary evidence for some benefits to participation but also the potential for harm.

DISCUSSION

There is a need for further research in this area using high-quality RCTs that address the risk of bias. It is important that lived experience peer mentors are monitored on key outcomes, provided with adequate training and ongoing supervision, and are reimbursed for their involvement.

PUBLIC SIGNIFICANCE

This systematic review is the first review to focus on the use of peer mentors recovered from an eating disorder contributing to interventions for people receiving treatment for an eating disorder. All included studies present quantitative results. Given the emerging interest of lived experience mentoring, understanding its effectiveness for both mentees and impacts on mentors continues to be of critical importance.

Patient and mentor language style matching as a predictor of working alliance, engagement with treatment as usual, and eating disorders symptoms over the course of an online guided self-help intervention for anorexia nervosa

OBJECTIVE

The aim of this study was to examine the processes involved in a guided self-help (GSH) pre-treatment intervention (RecoveryMANTRA) for patients with anorexia nervosa (AN), by measuring the levels of patient/mentor Language Style Matching (LSM). RecoveryMANTRA was supported by student mentors or peer mentors (recovered individuals) over six weekly chat-based sessions. We examined whether LSM during RecoveryMANTRA predicted patients'working alliance with the clinic therapist, motivation, eating disorder (ED) and general psychopathology. A further aim was to examine differences in LSM between student mentors and peer mentors.

METHOD

87 AN adults received RecoveryMANTRA plus treatment as usual. The LSM algorithm was used to calculate verbal attunement between patient and mentor. Participants were assessed at baseline and at the end of the intervention.

RESULTS

Both early (1^st session) and late (6^th session) LSM predicted higher working alliance with the clinic therapist. Moreover, late LSM predicted lower EDs symptoms at the end of the RecoveryMANTRA intervention. Patient/peer mentor dyads showed higher late verbal attunement than patient/student mentor dyads.

CONCLUSIONS

These findings suggests that in the early phase of treatment relational aspects can impact on engagement with treatment. Verbal attunement in a GSH for AN is associated with working alliance and better clinical outcome.

Informing care through lived experiences: perspectives of consumers and carers regarding dietetic care for eating disorders in Australia

PURPOSE

Dietitians are important members of eating disorder treatment teams. Previous research indicates little is known about the experience of receiving nutrition care for eating disorders. This study aimed to explore the perspectives of consumers and carers regarding the care received from primary care dietitians for eating disorders.

METHODS

This study qualitatively explored the perceptions of individuals aged ≥ 15 years, who (i) identified as having an eating disorder or (ii) had cared for someone with an eating disorder, and had received care from a dietitian in a primary care setting. Thematic analysis was used to identify themes from interview transcripts. Synthesized member checking was utilized to assess whether the identified themes resonated with participants' experiences. Twenty-four individuals (21 consumers, 3 carers) participated in a semi-structured interview. Seventeen participants completed member checking and all supported the identified themes and subthemes.

RESULTS

Three themes emerged inductively from the data: (1) valuing a person-centered approach to dietetic care; (2) the therapeutic alliance is central to engaging in dietetic care; and (3) sharing the complex journey.

CONCLUSIONS

This study advances the understanding of the aspects of dietetic care perceived as most helpful by consumers and carers. These insights highlight the importance of person-centeredness, empathy, trust and collaboration within eating disorder care. The findings can be used by dietitians and health professionals to inform practice. Further research is needed to understand how dietitians can be supported to provide optimal nutrition care to people and families impacted by eating disorders.

Informing mHealth and Web-Based Eating Disorder Interventions: Combining Lived Experience Perspectives With Design Thinking Approaches

BACKGROUND

App-based interventions designed to prevent and treat eating disorders have considerable potential to overcome known barriers to treatment seeking. Existing apps have shown efficacy in terms of symptom reduction; however, uptake and retention issues are common. To ensure that apps meet the needs and preferences of those for whom they were designed, it is critical to understand the lived experience of potential users and involve them in the process of design, development, and delivery. However, few app-based interventions are pretested on and co-designed with end users before randomized controlled trials.

OBJECTIVE

To address the issue, this study used a highly novel design thinking approach to provide the context and a lived experience perspective of the end user, thus allowing for a deeper level of understanding.

METHODS

In total, 7 young women (mean age 25.83, SD 5.34, range 21-33 years) who self-identified as having a history of body image issues or eating disorders were recruited. Participants were interviewed about their lived experience of body image and eating disorders and reported their needs and preferences for app-based eating disorder interventions. Traditional (thematic analysis) and novel (empathy mapping; visually depicting and empathizing with the user's personal experience) analyses were performed, providing a lived experience perspective of eating disorders and identifying the needs and preferences of this population in relation to app-based interventions for eating disorders. Key challenges and opportunities for app-based eating disorder interventions were also identified.

RESULTS

Findings highlighted the importance of understanding and identifying problematic eating disorder symptoms for the user, helpful practices for recovery that identify personal values and goals, the role of social support in facilitating hope, and aspects of usability to promote continued engagement and recovery.

CONCLUSIONS

Practical guidance and recommendations are described for those developing app-based eating disorder interventions. These findings have the potential to inform practices to enhance participant uptake and retention in the context of app-based interventions for this population.

Lived experience perspectives on a definition of eating disorder recovery in a sample of predominantly white women: a mixed method study

BACKGROUND

There has recently been a push for recovery-focused research in the eating disorder (ED) field, starting with a consensus definition of recovery. One definition, in particular, proposed by Bardone-Cone et al. [21] has received considerable attention given its transdiagnostic nature and validation studies. However, no studies to date have elicited lived experience views of this definition. The goal of the current study was to examine perspectives on this definition of recovery from individuals with a past or present ED and to determine whether participant agreement with the model differed based on diagnostic history or current symptom severity.

METHODS

Sixty-two individuals (95.2% women; 91.9% White/European) participated in a 1-2 h interview aimed at capturing their perspectives on ED recovery. Transcripts were analyzed using qualitative content analysis and codebook thematic analysis to examine agreement with and thoughts on Bardone-Cone's definition of recovery, respectively. Chi-squared tests of independence and binary logistic regression were computed to determine whether agreement with the definition differed across diagnostic history and self-reported symptoms.

RESULTS

Although some participants indicated acceptance of the definition, the majority expressed concerns related to its categorical nature, proposed criteria, feasibility, language, and applications. There were no differences in acceptance based on diagnostic history or current symptom severity.

CONCLUSION

A single definition of recovery does not seem to fit individuals' lived ED experience. Future research may benefit from distinguishing between recovery as an individually-defined phenomenon and related constructs such as remission (i.e., loss of diagnosis or absence of clinical symptoms). A more comprehensive multi-faceted, and person-centered model of recovery may have merit in clinical settings.

Identifying eating disorders in adolescents and adults with overweight or obesity: A systematic review of screening questionnaires

OBJECTIVE

This review aimed to examine the validity of self-report screening questionnaires for identifying eating disorder (ED) risk in adults and adolescents with overweight/obesity.

METHOD

Five databases were searched from inception to September 2020 for studies assessing validation of self-report ED screening questionnaires against diagnostic interviews in adolescents and adults with overweight/obesity. The review was registered with PROSPERO (https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=220013).

RESULTS

Twenty-seven papers examining 15 questionnaires were included. Most studies validated questionnaires for adults (22 of 27 studies), and most questionnaires (12 of 15) screened for binge eating or binge-eating disorder (BED). The Eating Disorder Examination Questionnaire (sensitivity = .16-.88, specificity = .62-1.0) and Questionnaire on Eating and Weight Patterns (sensitivity = .07-1.0, specificity = .0-1.0) were most frequently validated (six studies each). Five studies of three questionnaires were in adolescents, with the Adolescent Binge-Eating Disorder Questionnaire having highest sensitivity (1.0) but lower specificity (.27). Questionnaires designed to screen for BED generally had higher diagnostic accuracy than those screening for EDs in general.

DISCUSSION

Questionnaires have been well validated to identify BED in adults with overweight/obesity. Validated screening tools to identify other EDs in adults and any ED in adolescents with overweight/obesity are lacking. Thus, clinical assessment should inform the identification of patients with co-morbid EDs and overweight/obesity.

PUBLIC SIGNIFICANCE

Individuals with overweight/obesity are at increased risk of EDs. This review highlights literature gaps regarding screening for ED risk in this vulnerable group. This work presents possibilities for improving care of individuals with overweight/obesity by reinventing ED screening tools to be better suited to diverse populations.
