Eating disorders among queer and trans individuals: Implications for conceptualization, assessment, and treatment.

Eating disorders (EDs) have been traditionally viewed as a disorder affecting cisgender, heterosexual women. Yet, the prevalence of EDs among queer and trans (QnT) individuals, coupled with the lack of interventions that attend to contextual factors related to sexual orientation and gender identity, underscore a critical health disparity issue requiring urgent attention. Here, we first review factors pertaining to QnT individuals' minoritized sexual and gender identities that are important to consider in ED conceptualization for this population (e.g., minority stressors, identity-based body image standards). Next, we describe problematic assumptions present in existing ED assessment and propose more inclusive approaches. Lastly, we provide suggestions for practices that providers can implement within their treatment of EDs among QnT individuals.

Adolescents' perspectives on a novel digital treatment targeting eating disorders: a qualitative study.

BACKGROUND: Eating disorders in adolescence are associated with high psychological distress, impaired function and high comorbidity. Despite the severity, eating disorders remain highly underdiagnosed and untreated. Digital technology provides promising opportunities for treatment, however studies focusing on digital treatments for adolescents with eating disorders are lacking. The main aim of this study was to explore the perspectives of adolescents with lived experience of eating disorders on factors they deemed to be relevant in the development of a novel digital treatment. METHODS: A qualitative intervention development study using semi-structured individual interviews. Data collection, coding and analysis were conducted using the principles of reflexive thematic analysis. Participants were adolescents aged 16-19 years, with a self-reported diagnosis of anorexia nervosa, bulimia nervosa or binge eating disorder, currently in the final phase or completed psychological treatment for an eating disorder within the last five years. RESULTS: A total of 16 adolescents participated in the study, all females. Mean age was 17 ½ years (SD = 1.01). An in-depth understanding of the adolescents' perspectives was developed into three themes: Facilitating self-awareness and readiness to change; Strengthening interpersonal relationships and decreasing social isolation; Ensuring feeling seen and motivating regular use. CONCLUSIONS: This study provides a unique insight into the perspectives of adolescents with lived experience of eating disorders. The uptake and engagement can be optimized in a novel digital treatment for eating disorders by taking the adolescents perspectives into consideration.

Supportive Interventions in Managing Eating Disorders: A Review of the Evolving Medical Professional Landscape.

Background: The landscape of healthcare for medical professionals is undergoing significant changes during a global rise in obesity and mental health issues, particularly in the context of eating disorders. The COVID-19 pandemic, coupled with sedentary lifestyles and job loss, has exacerbated food obsession and mental health challenges, highlighting the need for effective treatments. Objective: This review aims to explore the impact of supportive interventions in managing eating disorders within the evolving landscape of medical professionals' approaches, focusing on the adoption of new tools and approaches. Methods: A comprehensive analysis of current literature and data sources was conducted to examine the healthcare landscape's transformation and its implications for treating eating disorders. Various treatment modalities, including therapy, education, medication, and support groups, were evaluated in light of recent changes in medical practice. Results: The review identified a growing body of research highlighting the effectiveness of supportive interventions, such as cognitive behavior therapy, mindfulness, and participation in peer support groups in improving emotional eating patterns and facilitating long-term weight management. The findings underscore the growing prevalence of obesity and mental health issues, with a significant portion of individuals experiencing food obsession and overeating. Despite this, recognition and treatment of obesity-related psychological issues remain inadequate, partly due to a shortage of mental health professionals. Treatment options for eating disorders may include bariatric surgery, therapy, education, medication, and supportive interventions. Support groups such as Overeaters Anonymous (OA) have shown promise in helping individuals manage eating disorders and achieve healthier lifestyles. Conclusions: The shifting healthcare landscape necessitates a proactive approach from medical professionals to address the complex relationship between obesity, mental health, and eating disorders. Integrating peer support groups and holistic treatment approaches alongside traditional medical interventions can enhance outcomes and promote long-term weight management.

Cognitive training via mobile app for addressing eating disorders' cognitions in adolescents: a randomized control trial protocol.

During adolescence, individuals are particularly vulnerable to developing eating disorders (EDs). To address the dysfunctional beliefs linked to these disorders, a new mobile app has been developed. This app, called GG eating disorders-Adolescents (GGED-AD), was created based on CBT to help adolescents work on their self-dialogue related to the core beliefs of eating disorders. The objective is to present the protocol for a randomized controlled trial to explore the efficacy of GGED-AD.Methods The study will be carried out in adolescents aged 13 to 16 from an educational center in the Valencian Community. The participants will be randomized into two groups: the experimental group will use the GGED-AD app during 14 consecutive days for approximately 5 min each day; and the control group will use a neutral app (GGNEUTRAL) during the same time. Both groups will complete instruments that assess dysfunctional beliefs related to eating disorders, eating symptoms, symptoms of depression and anxiety, body satisfaction and self-esteem before and after the intervention. A follow-up will be conducted one month later.Results A decrease in the degree of ascription to dysfunctional beliefs associated with eating disorders and eating symptomatology is expected, as well as an increase in body satisfaction and the self-esteem of the participants of the experimental group.Discussion The app in this study could help tackle and prevent ED-related symptoms in adolescents.Trial registration NCT06039514.

Updates in the treatment of eating disorders in 2023: a year in review in eating disorders: the Journal of treatment & Prevention.

Empirical evidence is unequivocal in illustrating that the majority of patients with eating disorders will not fully recover during treatment. To that end, the need for optimized treatment approaches and improved patient outcomes cannot be overstated. While empirical efforts are underway to optimize outcomes, this article reviews treatment-related research findings published in Eating Disorders: The Journal of Treatment & Prevention during 2023. Importantly, this review encapsulates research addressing (i) between-session patient behaviors, (ii) the integration of technology into treatment approaches, (iii) methods to augment emotional regulation in the context of eating disorder treatment, (iv) methods to measure progress, and potentially risk markers for patient dropout, during treatment, (v) optimizing treatment approaches for inpatient settings, and (vi) augmenting family therapy-based approaches. Incorporating novel technological advances may be critical in enhancing the scalability of eating disorder treatments, since treatment uptake remains an ongoing challenge for the field. Moreover, expanding the scope of non-outpatient eating disorder treatment settings, while ensuring fidelity to theoretical models developed in outpatient settings, is critical as treatment is effectively administer across the spectrum of levels of patient care.

Multi-family Therapy for Eating Disorders Across the Lifespan.

PURPOSE OF REVIEW: This review aims to report on recent evidence for multi-family therapy for eating disorders (MFT) across the lifespan. It is a narrative update of recent systematic, scoping and meta-analytic reviews. RECENT FINDINGS: There has been a recent increase in published theoretical, quantitative and qualitative reports on MFT in the past few years. Recent and emerging data continues to confirm MFT can support eating disorder symptom improvement and weight gain, for those who may need to, for people across the lifespan. It has also been associated with improved comorbid psychiatric symptoms, self-esteem and quality of life. Data are also emerging regarding possible predictors, moderators and mediators of MFT outcomes, as well as qualitative data on perceived change processes. These data suggest families with fewer positive caregiving experiences at the start of treatment may particularly benefit from the MFT context. Additionally, early change in family functioning within MFT may lead to improved outcomes at end of treatment. MFT is a useful adjunctive treatment across the lifespan for people with eating disorders. It helps to promote change in eating disorder and related difficulties. It has also been shown to support and promote broader family and caregiver functioning.

Pragmatic clinical trials to advance research in children and adolescents with eating disorders.

OBJECTIVE: To discuss the utility of pragmatic clinical trials (PCTs) to help advance research in eating disorders (EDs). METHODS: We describe challenges associated with traditional explanatory research trials and examine PCTs as an alternative, including a review of the PRECIS-2 tool. RESULTS: There are many challenges associated with the design and completion of traditional RCTs within the field of EDs. Pragmatic clinical trials are studies that closely align with conditions available in everyday practice and focus on outcomes that are relevant to patients and clinicians. Results of PCTS maximize applicability and generalizability to clinical settings. DISCUSSION: Available therapies established for the treatment of EDs provide remission rates that rarely exceed 50%, implying a need for additional research on new or adjunctive treatments. In addition to a general overview of PCTs, we draw upon published literature and our own experiences involving adjunctive olanzapine for the treatment of children and youth with anorexia nervosa to help highlight challenges associated with randomized controlled trial (RCT) design and implementation, and offer pragmatic suggestions that would allow patients greater choice in treatment trials, while at the same time capturing outcomes that are most likely to advance treatment efforts. CONCLUSIONS: Pragmatic clinical trials provide alternatives to RCT design that can help bolster research in EDs that aims to explore real-world effects of interventions. PUBLIC SIGNIFICANCE: Available therapies established for the treatment of eating disorders (EDs) in children and adolescents provide remission rates that rarely exceed 50%, implying a need for additional research on new or adjunctive treatments. In this article, we discuss the utility of pragmatic trials to help promote research that can help advance knowledge that is relevant to clinical care settings.

Guided self-help treatment for children and young people with threshold and subthreshold eating disorders: A pilot study protocol.

BACKGROUND: Prompt access to evidence-based treatment for children and young people with eating disorders is important for outcomes, yet the gap in service provision remains pervasive. Record levels of young people are waiting for eating disorder treatment and access to care is limited. Guided self-help interventions that are brief and require minimal clinician support have the potential to meet the unprecedented demand for treatment quickly and effectively. OBJECTIVE: To examine the feasibility, acceptability and proof of concept of a novel, CBT guided self-help intervention for children and young people with threshold and subthreshold eating disorders. METHODS: A single-arm, proof-of-concept pilot study of the CBT guided self-help intervention will be conducted. Children and young people (aged 11-19) with threshold and subthreshold eating disorders will receive a self-help intervention covering the core components of CBT, supported by 8 weekly guidance sessions delivered remotely. Clinical outcomes (eating-related psychopathology and associated impairment, changes in weight, depression, anxiety, and behavioural difficulties) will be assessed at baseline and post-intervention (12 weeks). Feasibility and acceptability of the intervention will be measured using various outcomes, including adherence to, and engagement with the intervention, rates of recruitment and retention, measure completion and treatment satisfaction. Qualitative data will also be collected for future intervention refinement. DISCUSSION: If the intervention is shown to produce clinical benefits in this pilot study, a fully powered randomised pilot study will be warranted with the ultimate goal of increasing access to psychological treatment for children and young people threshold and subthreshold eating disorders. ADMINISTRATIVE INFORMATION: This study protocol (S1 File) adheres to the guidelines outlined in the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) checklist for trial protocols [1, 2] which can be found in S1 Checklist. The numbers in parentheses in this protocol correspond to the item numbers in the SPIRIT checklist. The order of items has been modified to group similar items.

Eating disorders: is there a correlation between severity of physical compromise and admission outcomes?

BACKGROUND: The Medical Emergencies in Eating Disorders (MEED) report was first released by the Royal College of Psychiatrists in 2022 (updated 2023) to aid clinicians in recognising medical compromise due to an eating disorder and to provide guidance for management. AIMS: This study looked at admissions over 5 years to explore whether there is a correlation between MEED medical compromise parameters and three outcomes: length of stay, detainment under the Mental Health Act 1983, and discharge destination. METHODS: A retrospective study of 26 patients admitted to a large teaching hospital for an eating disorder between 2018 and 2023. The risk assessment from the MEED report was used to create a score for physical compromise and analysed to determine whether there was a correlation between the score and discharge destination, detainment under the Mental Health Act and length of stay. FINDINGS: Demographic data were comparable with larger studies, with increasing numbers and 19.2% having autism spectrum disorder. There was no correlation between the scoring tool and detainment under the Act, discharge destination or length of stay. CONCLUSION: Increasing numbers of patients are presenting with eating disorders. Physical compromise was not a predictor for admission outcomes, but this could be further explored in larger studies.

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

PURPOSE: Treatment resistance is a significant challenge in addressing eating disorders (EDs). The Autonomous and Controlled Motivation for Treatment Questionnaire (ACMTQ) has been previously validated in ED populations to assess patients' motivation for treatment. This study aimed to validate the ACMTQ in the Italian language (ACMTQ-ITA) and evaluate its psychometric properties. METHODS: We recruited a clinical sample of adults aged 18 or older, diagnosed with EDs, proficient in the Italian language, and providing written informed consent. Participants with psychiatric comorbidities such as schizophrenia, bipolar disorder, and substance use disorder were excluded from the study. Validity of the ACMTQ-ITA was assessed using reliability analysis with Cronbach's α and McDonald's ω estimates, and Confirmatory Factor Analysis (CFA). RESULTS: Results from the reliability analysis confirmed the internal consistency of the Autonomous Motivation (AM) factor (α = 0.82, ω = 0.82), the Controlled Motivation (CM) factor (α = 0.76, ω = 0.77), and the ACMTQ-ITA overall score (α = 0.79). The CFA confirmed the two-factor solution (i.e., AM and CM) identified in the original validation of the ACMTQ (Comparative Fit Index = 0.92, Akaike Information Criterion = 3427.26, Bayesian Information Criterion = 3486.82; Root Mean Square Error of Approximation = 0.08, Standardized Root Mean Square Residual = 0.09). CONCLUSION: The ACMTQ-ITA emerged as a valid and reliable tool for measuring motivation for treatment in individuals with EDs. Its implementation may facilitate the comprehension of treatment motivation, offering valuable clinical insights and implications for health management practices. LEVEL OF EVIDENCE: Level V, descriptive studies.

Pediatric Feeding Disorder and the School-Based Speech-Language Pathologist: An Evidence-Based Update for Clinical Practice.

PURPOSE: This prologue introduces the forum "Pediatric Feeding Disorder and the School-Based SLP: An Evidence-Based Update for Clinical Practice" and informs the reader of the scope of articles presented. METHOD: The guest prologue author provides a brief history of pediatric feeding and swallowing services in the public-school setting, including previous forums on swallowing and feeding services in the schools (Logemann & O'Toole, 2000; McNeilly & Sheppard, 2008). The concepts that have been learned since the 2008 forum are shared. The contributing authors in the forum are introduced, and a summary is provided for each of the articles. CONCLUSIONS: The articles provide evidence-based information on topics that are uniquely of interest to school-based speech-language pathologists managing pediatric feeding and swallowing in their districts. The topics shared in this forum range from relevant information on anatomy, physiology, developmental milestones, and differential diagnosis to therapeutic practice when identifying and treating pediatric feeding and swallowing in the school setting. The forum also includes focused articles on the necessity of collaboration with families during the treatment process, current information on legal parameters dealing with school-based pediatric feeding disorder services, and a framework for assessment and treating pediatric feeding disorder in the school setting.

Examining the role of artificial intelligence to advance knowledge and address barriers to research in eating disorders.

OBJECTIVE: To provide a brief overview of artificial intelligence (AI) application within the field of eating disorders (EDs) and propose focused solutions for research. METHOD: An overview and summary of AI application pertinent to EDs with focus on AI's ability to address issues relating to data sharing and pooling (and associated privacy concerns), data augmentation, as well as bias within datasets is provided. RESULTS: In addition to clinical applications, AI can utilize useful tools to help combat commonly encountered challenges in ED research, including issues relating to low prevalence of specific subpopulations of patients, small overall sample sizes, and bias within datasets. DISCUSSION: There is tremendous potential to embed and utilize various facets of artificial intelligence (AI) to help improve our understanding of EDs and further evaluate and investigate questions that ultimately seek to improve outcomes. Beyond the technology, issues relating to regulation of AI, establishing ethical guidelines for its application, and the trust of providers and patients are all needed for ultimate adoption and acceptance into ED practice. PUBLIC SIGNIFICANCE: Artificial intelligence (AI) offers a promise of significant potential within the realm of eating disorders (EDs) and encompasses a broad set of techniques that offer utility in various facets of ED research and by extension delivery of clinical care. Beyond the technology, issues relating to regulation, establishing ethical guidelines for application, and the trust of providers and patients are needed for the ultimate adoption and acceptance of AI into ED practice.

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.

OBJETIVO: Esta revisión exploratoria buscó mapear el alcance de la literatura sobre el uso de ensayos de diseño adaptativo en la investigación de trastornos de conducta alimentaria. MÉTODO: Se realizó una búsqueda sistemática de literatura en Medline, Scopus, PsycInfo, Econlit y CINAHL. Se incluyeron artículos que informaban sobre una intervención dirigida a cualquier tipo de trastorno de conducta alimentaria (incluyendo anorexia nerviosa, bulimia nerviosa, trastorno por atracón y otros trastornos de la conducta alimentaria o de la ingestión de alimentos especificados) y empleaban el uso de un ensayo de diseño adaptativo para evaluar la intervención. Dos revisores independientes examinaron las citas para su inclusión, y la abstracción de datos fue realizada por un revisor y verificada por otro. RESULTADOS: Identificamos cinco ensayos de diseño adaptativo dirigidos a la anorexia nerviosa, bulimia nerviosa y trastorno por atracón realizados en Estados Unidos y Australia. Todos emplearon el cambio adaptativo de brazo de tratamiento basado en la respuesta temprana al tratamiento e identificaron reglas de detención a priori. Ninguno de los estudios incluyó análisis del Valor de la Información para guiar las decisiones de diseño adaptativo y ninguno incluyó perspectivas de experiencia vivida. DISCUSIÓN: El uso limitado de diseños adaptativos en ensayos de trastornos de conducta alimentaria representa una oportunidad perdida para mejorar los objetivos de reclutamiento, tasas de deserción, resultados del tratamiento y eficiencia del ensayo. Esbozamos la gama de metodologías adaptativas, cómo podrían aplicarse a la investigación de trastornos de conducta alimentaria, y las consideraciones operativas y estadísticas específicas relevantes para los ensayos de diseño adaptativo. PÚBLICA SIGNIFICANCIA: Los ensayos de diseño adaptativo se emplean cada vez más como alternativas flexibles y eficientes a los diseños de ensayos fijos, pero no se utilizan con frecuencia en la investigación de trastornos de conducta alimentaria. Esta primera revisión exploratoria identificó cinco ensayos de diseño adaptativo dirigidos a la anorexia nerviosa, bulimia nerviosa y trastorno por atracón que emplearon la metodología adaptativa de cambio de brazo de tratamiento. Hacemos recomendaciones sobre el uso de ensayos de diseño adaptativo para futuros ensayos de trastornos de conducta alimentaria.

"That's not at all what I needed" trans adults' perspectives on trans-affirming primary care and eating disorders.

Transgender and gender diverse adults, referred to collectively as trans, experience eating disorders (EDs) at high rates and struggle to find primary care providers (PCPs) knowledgeable in both gender-affirming care and EDs. Most research regarding healthcare experiences of trans people with EDs focuses on specialized treatment. This qualitative study explored the experiences of trans patients with ED symptoms in trans-affirming primary care, which offers clinical support for gender affirmation in the context of interpersonally gender-affirming primary care services. Twenty-two participants were recruited via social media to participate in focus groups (n = 5). Researchers utilized thematic analysis. Participants reported gender-affirming and non-affirming experiences, experienced unwelcome comments from providers regarding bodies and gender, encountered barriers to disclosing their ED symptoms, felt transition-related medical care supported recovery but did not always resolve their ED symptoms, felt they had to self-advocate, and wanted their providers to recognize them as whole people (beyond their ED and transness) who experience joy. Importantly, despite being trans-affirming, participants critiqued trans-affirming primary care as perpetuating weight stigma and binary gender norms. Participants recommended providers receive ED training, implement universal ED screening, and explore how sociocultural norms regarding weight and gender negatively impact trans health outcomes.

Established and emerging treatments for eating disorders.

Eating disorders (EDs) are common mental health conditions that carry exceedingly high morbidity and mortality rates. Evidence-based treatment options include a range of psychotherapies and some, mainly adjunctive, pharmacological interventions. However, around 20-30% of people fail to respond to the best available treatments and develop a persistent treatment-refractory illness. Novel treatments for these disorders are emerging, but their efficacy and clinical relevance need further investigation. In this review article, we first outline the evidence-base for the established treatments of the three 'classical' EDs [anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED)]. We then review research on some of the most promising emerging treatment modalities, discussing the questions and challenges that remain.

Individual differences in motivation to change in individuals with eating disorders: A systematic review.

OBJECTIVE: Motivation to change has been suggested to significantly impact treatment outcomes in eating disorders (EDs). This review will investigate factors associated with motivation to change in EDs with the aim of supporting clinicians to be aware and sensitive to factors that might obstruct recovery and to inform motivation-based interventions. METHOD: Using PRISMA guidelines, this article identified 24 studies through database searches meeting eligibility criteria. Only correlates of motivation were identified, limiting the ability of this review to identify causal relationships. Factors that changed alongside changes in motivation were identified from longitudinal studies. RESULTS: This review identified factors such as individual characteristics, co-morbid psychopathology, lack of treatment autonomy and relationships with others to be associated with motivation to change in individuals with EDs. In addition, motivation to change significantly increased alongside self-esteem and identity re-negotiation when measured longitudinally. DISCUSSION: Motivational interviewing can typically focus on exploring ambivalence to treatment, identifying goals and values, and increasing self-efficacy. However, this review identifies individual and relational factors to be particularly significant and may obstruct recovery from an ED. As such, evidence-based targets have been identified to inform clinicians and motivation-based interventions. PUBLIC SIGNIFICANCE: Knowledge of factors associated with motivation to change in EDs is important to understand those who may have poorer treatment outcomes. Motivation may be improved by supporting individuals' relationship with others and tailoring interventions according to temperament and personality traits. Utilizing an individual's social support as they enter ED treatment may be effective in maximizing motivation to recover.

OBJETIVO: Se ha sugerido que la motivación al cambio impacta significativamente en los resultados del tratamiento en los trastornos de la conducta alimentaria (TCAs). Esta revisión investigará los factores asociados con la motivación al cambio en los TCAs con el objetivo de apoyar a los clínicos para que estén conscientes y sensibles a los factores que podrían obstaculizar la recuperación e informar las intervenciones basadas en la motivación. MÉTODO: Siguiendo las guías PRISMA, este artículo identificó 24 estudios a través de búsquedas en bases de datos que cumplían con los criterios de elegibilidad. Solo se identificaron correlatos de la motivación, lo que limita la capacidad de esta revisión para identificar relaciones causales. Los factores que cambiaron junto con los cambios en la motivación se identificaron a partir de estudios longitudinales. RESULTADOS: Esta revisión identificó factores como características individuales, psicopatología comórbida, falta de autonomía en el tratamiento y relaciones con otros como asociados con la motivación al cambio en individuos con TCAs. Además, la motivación al cambio aumentó significativamente junto con la autoestima y la renegociación de la identidad cuando se midió longitudinalmente. DISCUSIÓN: La entrevista motivacional típicamente puede centrarse en explorar la ambivalencia hacia el tratamiento, identificando metas y valores, y aumentando la autoeficacia. Sin embargo, esta revisión identifica factores individuales y relacionales como particularmente significativos y que pueden obstaculizar la recuperación de un TCA. Como tal, se han identificado objetivos basados en evidencia para informar a los clínicos y a las intervenciones basadas en la motivación.

Timing matters in (mis)identifying moderators and mediators of digital interventions for eating disorders: Commentary on McClure et al. (2023).

This commentary addresses the challenges in identifying consistent moderators and mediators of psychological treatments for eating disorders (EDs), as highlighted by McClure et al. (International Journal of Eating Disorders, 2023) in their systematic review. Specifically, we discuss the often-overlooked importance of temporal context (when an intervention is delivered), alongside sociodemographic and symptom type (for whom an intervention is delivered), in understanding and optimizing treatment engagement and effectiveness. We outline how individuals' fluctuating levels of motivation and receptivity across different "pivotal moments" in the help-seeking process-including initial outreach and self-screening, ongoing care engagement, and post-discharge-can dynamically impact interventions' relevance and impacts. We also overview how Just-In-Time Adaptive Interventions in digital mental health interventions can be harnessed to simultaneously consider "when" and "for whom" ED interventions can exert the greatest benefits. We conclude with several recommendations for conducting ED intervention and implementation research that integrate timing into support delivery and study design, enabling a deeper understanding of not just how and for whom, but when, ED interventions can be most effective.

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

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