RESUMO
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.

OBJECTIVE: Individuals with eating disorders (EDs) often do not receive evidence-based care, such as interpersonal psychotherapy (IPT), partly due to lack of accessible training in these treatments. The standard method of training (i.e., in-person workshops) is expensive and time consuming, prompting a need for more scalable training tools. The primary aim of this pilot and open trial was to examine the effects of an IPT online training platform on training outcomes (i.e., IPT fidelity, knowledge, and acceptance) and, secondarily, whether online training was different from in-person training (using a comparative sample from a separate study) in terms of training outcomes and patient symptoms. METHOD: Participants were therapists (N = 60) and student patients (N = 42) at 38 college counseling centers. Therapists completed baseline questionnaires and collected data from a student patient with ED symptoms. Therapists then participated in an IPT online training program and completed post-training assessments. RESULTS: Following online training, acceptance of evidence-based treatments, therapist knowledge of IPT, therapist acceptance of IPT, and treatment fidelity increased; acceptance of online training was high at baseline and remained stable after training. Using the 90% confidence interval on outcome effect sizes, results suggested IPT online training was not different from in-person training on most outcomes. Results are based on 60% of therapists who originally enrolled due to high dropout rate of therapist participants. CONCLUSIONS: Findings from this preliminary pilot study support the use of IPT online training, which could increase access to evidence-based ED treatment and improve patient care. PUBLIC SIGNIFICANCE: Lack of accessible therapist training has contributed to many therapists not delivering, and therefore many patients not receiving, evidence-based treatment. This study evaluated a highly disseminable online training and compared outcomes to traditional in-person training and found that training and patient outcomes were not different. Online training has the potential to enhance access to evidence-base care, which could in turn optimize patient outcomes.

OBJECTIVE: Food insecurity is associated with eating disorder psychopathology. This Spotlight describes why food pantries could be promising partners for disseminating and implementing eating disorder interventions. METHOD: Researchers are increasingly collaborating with community-based organizations to improve access to health interventions, because community-based organizations overcome structural barriers to traditional healthcare by being embedded physically in the communities they serve, convenient to visit, regularly frequented, and led by trusted community members. RESULTS: We describe strategies we have identified with our partner to disseminate and implement our digital intervention for binge eating; we also discuss ways we support the pantry's needs to improve the mutuality of the partnership. DISCUSSION: The potential benefits of partnerships with food pantries make this an area to explore further. Future research directions include deeply engaging with food pantries to determine how pantries benefit from disseminating and implementing eating disorder interventions and how to intervene in non-stigmatizing ways, what resources they need to sustainably support these efforts, what eating disorder intervention modalities guests are willing and able to engage with, what intervention adaptations are needed so individuals with food insecurity can meaningfully engage in eating disorder intervention, and what implementation strategies facilitate uptake to intervention sustainably over time.
RESUMO
This Virtual Issue of the International Journal of Eating Disorders honors the legacy of the late Dr. C. Barr Taylor in the eating disorders (EDs) field. For decades, Dr. Taylor led the way in not only conducting the research needed to achieve the ultimate goal of making affordable, accessible, and evidence-based care for EDs available to all, but also nurturing the next generation of scientific leaders and innovators. Articles included in this Virtual Issue are a selection of Dr. Taylor's published works in the Journal in the past decade, spanning original research, ideas worth researching, commentaries, and a systematic review. We hope this Virtual Issue will inspire the next generation of research in EDs, and equally, if not more importantly, the next generation of young investigators in the field. We urge the field to continue and build upon Dr. Taylor's vision-to increase access to targeted prevention and intervention for EDs in innovative and forward-thinking ways-while embracing his unique and powerful mentorship style to lift up early career investigators and create a community of leaders to address and solve our field's biggest challenges.
RESUMO
PURPOSE OF REVIEW: Digital (i.e., online, mobile) interventions have potential to increase access to care for people with eating disorders, but engagement with digital interventions has been challenging. Human-centered design is a methodology that centralizes the design of technologies on the people who will be using them and the settings in which they will be implemented, to yield solutions with high engagement and clinical impact. The paper presents an overview of the human-centered design process, followed by a review of publications that have applied design methods to digital interventions for eating disorders. RECENT FINDINGS: Design research has been conducted via needs assessments, prototyping and usability studies, and during ongoing delivery of digital eating disorder interventions. There has been growing research applying design methods to digital interventions for eating disorders. Additional opportunities include designing for implementation, designing for equity, and designing for the optimization of digital interventions over time.

Digital guided self-help for eating disorders (GSH-ED) can reduce treatment disparities. Understanding program participants' interests throughout the program can help adapt programs to the service users' needs. Participants were 383 college students receiving a digital GSH-ED, who were each assigned a coach to help them better utilize the intervention through text correspondence. A thematic and affective analysis of the texts participants had sent found they primarily focused on: strategies for changing their ED-related cognitions, behaviors, and relationships; describing symptoms without expressing an active endeavor to change; and participants' relationship with their coach. Most texts also expressed affect, demonstrating emotional engagement with the intervention. Findings suggest that participants in GSH-ED demonstrate high involvement with the intervention, and discuss topics that are similar to those reported in clinician-facilitated interventions. The themes discussed by digital program participants can inform future iterations of GSH-ED, thereby increasing scalability and accessibility of digital evidence-based ED interventions.

Smartphone apps are increasingly being developed to address mental health problems, including eating disorders. Yet a review by O'Leary and Torous (2022) revealed the dearth of publicly available evidence-based apps for eating disorders, despite growing research in this area in recent years. The lack of publicly available evidence-based apps is problematic for society and reflects a gap in the research-to-practice translation of the advances that have been made through academic research in this area. We detail barriers that academic researchers face to such translation, including the lack of incentives and pathways for making these interventions available beyond the academic institutions in which they are often created. The effective translation of eating disorder apps, and other digital approaches, from research to practice will require new approaches, including bolstering successful and sustainable translation through partnerships across sectors, being more proactive toward research-to-practice translation, and designing more sustainable digital interventions. Harnessing such approaches can improve the availability of evidence-based eating disorder apps and other digital approaches. Additionally, academic researchers are encouraged to be advocates within their institutions and with funding agencies to find ways to better incentivize and fund these efforts.

OBJECTIVE: Racial discrimination is a stressor for young Black women that leads to poor health outcomes, including maladaptive eating. This study presents findings on racial discrimination and maladaptive eating behaviors (overeating, LOC eating) using ecological momentary assessment (EMA). METHODS: Black emerging adult women (N = 27) with overweight or obesity participated in a 14-day EMA study examining exposure to racial discrimination, eating behaviors, and racial identity. Frequencies and chi-square tests were used to characterize the type of racial discrimination experienced and frequency of overeating. Mixed effect ordinal logistic regression models were used to assess the relation between racial discrimination and maladaptive eating. Moderation analysis was conducted by creating interaction terms for discrimination and racial identity variables. RESULTS: 81.5% of participants reported experiencing racial discrimination. Young Black women reporting exposure to racial discrimination were more likely to endorse higher levels of both overeating and LOC eating compared to times when discrimination was not experienced (p < .0001). Racial identity moderated the link between racial discrimination and maladaptive eating (overeating, LOC) such that reporting greater levels of private regard buffered the deleterious effect of racial discrimination. Higher levels of public regard exacerbated the association between racial discrimination and both overeating, and LOC. Higher centrality worsened the relation between racial discrimination and LOC. CONCLUSION: Young Black women might use maladaptive eating to cope with exposure to racial discrimination, which underscores the importance of examining the link between racism and disordered eating, particularly among Black women submerged in a society that continuously exposes them to racial discrimination. PUBLIC SIGNIFICANCE: Emerging adult Black women are exposed to racial discrimination daily. In theory, exposure to racial discrimination could contribute to overeating and loss of control eating in this population. Using ecological momentary assessment, to capture experiences and eating behaviors in the moment they occur, this project quantified the magnitude of racial discrimination and how it was associated with maladaptive eating behaviors. Further, it examined ways in which racial identity was linked to this association.

OBJECTIVE: This study explored consumers' perspectives on self-monitoring, a common feature in behavioral interventions that helps inform consumers' progress and answer their questions, to learn what outcome metrics matter to consumers and whether self-selection of these metrics leads to greater engagement (i.e., compliance, satisfaction) in self-monitoring than monitoring only default options. METHODS: In a proof-of-concept randomized trial, 48 adult participants were randomly assigned to "clinician-determined monitoring" or "clinician + self-determined monitoring" conditions. Before starting monitoring, all participants shared outcomes that would matter to them in a mobile intervention for binge eating and weight management. Then, for 3 weeks, participants in the "clinician-determined" condition monitored their weight and binge-eating episodes, and participants in the "clinician + self-determined" condition monitored these and another metric of their choosing. After, satisfaction and compliance were assessed. RESULTS: Participants identified 116 metrics, grouped into 12 themes, that mattered to them. During monitoring, participants in the "clinician + self-determined" condition monitored 41 metrics. Surprisingly, participants in the "clinician-determined" condition also monitored metrics besides weight and binge eating. This resulted in a failure of our experimental manipulation, which represents a significant limitation of this research. No significant differences emerged in satisfaction or compliance between conditions. DISCUSSION: Although our proof-of-concept trial yielded null quantitative results, findings also suggested binge eating and weight management interventions may benefit from including an individually customizable monitoring option in addition to default metrics, warranting testing in future research. PUBLIC SIGNIFICANCE: Examining consumers' self-monitoring preferences for a mobile intervention for binge eating and weight management revealed a variety of metrics that matter to consumers, although binge eating and weight were still most valued. Findings from our proof-of-concept trial suggest design implications of encouraging an individually customizable monitoring option, in addition to default metrics, which needs to be tested in future research over a longer period and during actual mobile intervention delivery.

Promoting representation of historically marginalized racial and ethnic populations in the eating disorders (EDs) field among professionals and the populations studied and served has long been discussed, with limited progress. This may be due to a reinforcing feedback loop in which individuals from dominant cultures conduct research and deliver treatment, participate in research, and receive diagnoses and treatment. This insularity maintains underrepresentation: EDs in historically marginalized populations are understudied, undetected, and undertreated. An Early Career Investigators Workshop generated recommendations for change that were not inherently novel but made apparent that accountability is missing. This paper serves as a call to action to spearhead a paradigm shift from equality to equity in the ED field. We provide a theoretical framework, suggest ways to disrupt the feedback loop, and summarize actionable steps to increase accountability in ED leadership and research toward enhancing racial/ethnic justice, equity, diversity, and inclusion (JEDI). These actionable steps are outlined in the service of challenging our field to reflect the diversity of our global community. We must develop and implement measurable metrics to assess our progress toward increasing diversity of underrepresented racial/ethnic groups and to address JEDI issues in our providers, patients, and research participants.

OBJECTIVE: To explore predictors of treatment seeking and uptake among individuals following an online eating disorders (EDs) screen in the U.S. disseminated by the National Eating Disorders Association. METHOD: Respondents who screened at risk or positive for a probable ED from 04/2019 to 05/2021 (N = 263,530) were eligible to complete a 2-month follow-up survey that assessed treatment seeking and uptake after being offered referral options following screening. Analyses were conducted using chi-square tests or logistic regressions. RESULTS: Sixty thousand thirty-four respondents (22.8%) opted-in to the follow-up survey, of whom 2276 (3.8%) completed it. Of the final analytic sample (n = 1922), 35.7% of respondents reported seeking and 22.4% reported receiving treatment. Treatment seeking and uptake were more common among respondents who were female, White, or >24 years of age; uptake was more common among respondents who were non-Hispanic or higher income. Elevated shape/weight concerns were significantly, albeit modestly, associated with reduced likelihood to receive treatment. DISCUSSION: Demographic differences in treatment seeking and uptake highlight the need to optimize ED screening tools/feedback to meet the needs of underserved groups and to address stereotypes and structural barriers that may interfere. Research is also needed to identify barriers to uptake among those with elevated shape/weight concerns. PUBLIC SIGNIFICANCE: Relatively low rates of treatment seeking and uptake were observed, particularly among underserved groups, 2 months following a widely disseminated online eating disorders screen. Optimization of online eating disorder screening tools and delivery of feedback and referral information may be needed to increase health care utilization.

BACKGROUND: Patients with systemic lupus erythematous (SLE) experience psychological comorbidities and impaired quality of life (QOL). We conducted a systematic review to examine the efficacy of non-pharmacological interventions for improving psychological outcomes and/or QOL in patients with SLE. To expand on a previous systematic review in this area and enhance our understanding of efficacious interventions for this population, our search included quasi-experimental and experimental studies of interventions delivered or supported by remote methods (including digitally) or in person. METHODS: A comprehensive literature search was conducted with a research librarian using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered before data extraction on the international prospective register of systematic reviews PROSPERO Web site (CRD42020154962). The search included controlled-vocabulary and title/abstract terms related to non-pharmacological interventions for SLE published through October 2019 in MEDLINE (Ovid), Cochrane Library databases (Wiley), Embase (Elsevier), CINAHL (EBSCO), PsycINFO (EBSCO), Web of Science (Clarivate), ACM Digital (Association of Computer Machinery), and IEEE Xplore. Studies were synthesized using a systematic narrative synthesis framework. Risk of bias was assessed. RESULTS: Twenty-three studies were included: 21 randomized controlled trials and two quasi-experimental studies. Non-pharmacological diet, physical activity, psychological, and course-based interventions improved QOL and psychological outcomes, and were delivered in traditional settings (e.g., hospital) or remotely. No studies assessing digital non-pharmacological interventions were identified in our search. Quality assessments showed serious risk of bias for the two quasi-experimental studies, and high risk of bias in a subset of experimental studies. CONCLUSIONS: Non-pharmacological interventions benefit patients with SLE. Future research should include more representative samples in rigorous evaluations and consider ways to incorporate digital technologies to increase accessibility.

Gastrointestinal (GI) problems are common in individuals with eating disorders (EDs) and associated with distress, impairment, and increased healthcare utilization. GI symptoms may be exacerbated by meals and other interventions central to ED recovery thereby contributing to negative clinical outcomes. Informed by models emphasizing the role of the brain-gut axis in the expression of GI symptoms, this article describes a program of research to adapt "brain-gut psychotherapies" for EDs. First, the role of the brain-gut axis in GI symptoms is described, and evidence-based brain-gut psychotherapies are reviewed, with an emphasis on cognitive behavioral therapy for GI disorders and gut-directed hypnotherapy. Next, future directions for research in EDs to (a) understand the impact of GI symptoms on illness course and outcome; (b) clarify target engagement; (c) evaluate brain-gut psychotherapies; and (d) optimize intervention reach and delivery are described. We present a conceptual model that emphasizes GI-specific anxiety and altered gut physiology as targets of brain-gut psychotherapies in EDs, and discuss several issues that need to be addressed in designing clinical trials to test these interventions. We also describe how engagement with multidisciplinary stakeholders and use of digital tools could speed translation from the laboratory to clinical settings.

BACKGROUND: ICare represents a consortium of European Investigators examining the effects of online mental health care for a variety of common mental health disorders provided in a variety of settings. This article provides an overview of the evidence of effectiveness for Internet-based treatment for four common mental health disorders that are the focus of much of this work: depression, anxiety, substance abuse and eating disorders. METHODS: The overview focused primarily on systematic reviews and meta-analyses identified through PubMed (Ovid) and other databases and published in English. Given the large number of reviews specific to depression, anxiety, substance abuse and/or eating disorders, we did not focus on reviews that examined the effects of Internet-based interventions on mental health disorders in general. Each article was reviewed and summarized by one of the senior authors, and this review was then reviewed by the other senior authors. We did not address issues of prevention, cost-effectiveness, implementation or dissemination, as these are addressed in other reviews in this supplement. RESULTS: Across Internet-based intervention studies addressing depression, anxiety, substance abuse and eating disorders primarily among adults, almost all reviews and meta-analyses found that these interventions successfully reduce symptoms and are efficacious treatments. Generally, effect sizes for Internet-based interventions treating eating disorders and substance abuse are lower compared with interventions for depression and anxiety. CONCLUSIONS: Given the effectiveness of Internet-based interventions to reduce symptoms of these common mental health disorders, efforts are needed to examine issues of how they can be best disseminated and implemented in a variety of health care and other settings.

The unprecedented COVID-19 crisis presents an imperative for mental health care systems to make digital mental health interventions a routine part of care. Already because of COVID-19, many therapists have rapidly moved to using telehealth in place of in-person contact. In response to this shift, Waller and colleagues compiled a series of expert recommendations to help clinicians pivot to delivering teletherapy to address eating disorders during COVID-19. However, numerous barriers still impede widespread adoption and implementation of digital interventions. In this commentary, we aim to extend the recommendations for clinicians offered by Waller and colleagues by presenting a roadmap of the systems- and policy-level requirements that are needed. We advocate for addressing barriers associated with training, licensing, safety, privacy, payment, and evaluation, as these factors have greatly limited use of these promising interventions. We also indicate that longer-term goals should include introducing truly innovative digital mental health practices, such as stepped-care models and simultaneously providing preventive and self-management services in addition to clinical services, into the health care system. Now is the time to catalyze change and comprehensively address the barriers that have prevented widespread delivery of these efficacious digital services to the millions of people who would benefit.

OBJECTIVE: User-centered design can improve engagement with and the potential efficacy of behavioral interventions, but is underutilized in health care. This work demonstrates how design methodologies can inform the design of a mobile behavioral intervention for binge eating and obesity. METHOD: A needs assessment was conducted with end-users (N = 22 adults with obesity and recurrent binge eating [≥12 episodes in 3 months] who were interested in losing weight and addressing binge eating), which included assessing participants' past/current and future willingness to engage with 20 treatment targets for managing binge eating and weight. Targets focused on improving dietary intake, increasing physical activity, and reducing overvaluation of weight and/or shape, unhealthy weight control practices, and negative affect. RESULTS: Participants' past and current use of targets varied. For all targets except those addressing unhealthy weight control practices, on average, participants had increasing levels of willingness to try targets. Among participants not currently using a target, at least some were willing to use every target again. DISCUSSION: Findings inform ways to personalize how users begin treatment. Furthermore, this study exemplifies how user-centered design can inform ways to ensure that digital interventions are designed to meet end-users' needs to improve engagement and clinical impact.

OBJECTIVE: Scaling an online screen that provides referrals may be key in closing the treatment gap for eating disorders (EDs), but we need to understand respondents' help-seeking intentions and behaviors after receiving screen results. This study reported on these constructs among respondents to the National Eating Disorders Association online screen who screened positive or at high risk for an ED. METHOD: Respondents completed the screen over 18 months (February 9, 2018-August 28, 2019). Those screening positive or at high risk for an ED (n = 343,072) had the option to provide data on help-seeking intentions (after screen completion) and behaviors (2-month follow-up). RESULTS: Of eligible respondents, 4.8% (n = 16,396) provided data on help-seeking intentions, with only 33.7% of those reporting they would seek help. Only 7.6% of eligible respondents opted in to the 2-month follow-up, with 10.6% of those completing it (n = 2,765). Overall, 8.9% of respondents to the follow-up reported being in treatment when they took the screen, 15.5% subsequently initiated treatment, and 75.5% did not initiate/were not already in treatment. DISCUSSION: Preliminary results suggest that among the small minority who provided data, only one-third expressed help-seeking intentions and 16% initiated treatment. Online screening should consider ways to increase respondents' motivation for and follow-through with care.

BACKGROUND: Digital health interventions (DHIs) are poised to reduce target symptoms in a scalable, affordable, and empirically supported way. DHIs that involve coaching or clinical support often collect text data from 2 sources: (1) open correspondence between users and the trained practitioners supporting them through a messaging system and (2) text data recorded during the intervention by users, such as diary entries. Natural language processing (NLP) offers methods for analyzing text, augmenting the understanding of intervention effects, and informing therapeutic decision making. OBJECTIVE: This study aimed to present a technical framework that supports the automated analysis of both types of text data often present in DHIs. This framework generates text features and helps to build statistical models to predict target variables, including user engagement, symptom change, and therapeutic outcomes. METHODS: We first discussed various NLP techniques and demonstrated how they are implemented in the presented framework. We then applied the framework in a case study of the Healthy Body Image Program, a Web-based intervention trial for eating disorders (EDs). A total of 372 participants who screened positive for an ED received a DHI aimed at reducing ED psychopathology (including binge eating and purging behaviors) and improving body image. These users generated 37,228 intervention text snippets and exchanged 4285 user-coach messages, which were analyzed using the proposed model. RESULTS: We applied the framework to predict binge eating behavior, resulting in an area under the curve between 0.57 (when applied to new users) and 0.72 (when applied to new symptom reports of known users). In addition, initial evidence indicated that specific text features predicted the therapeutic outcome of reducing ED symptoms. CONCLUSIONS: The case study demonstrates the usefulness of a structured approach to text data analytics. NLP techniques improve the prediction of symptom changes in DHIs. We present a technical framework that can be easily applied in other clinical trials and clinical presentations and encourage other groups to apply the framework in similar contexts.

PURPOSE: The US Preventive Services Task Force recommends screening for depression in the general adult population. Although screening questionnaires for depression and anxiety exist in primary care settings, electronic health tools such as computerized adaptive tests based on item response theory can advance screening practices. This study evaluated the validity of the Computerized Adaptive Test for Mental Health (CAT-MH) for screening for major depressive disorder (MDD) and assessing MDD and anxiety severity among adult primary care patients. METHODS: We approached 402 English-speaking adults for participation from a primary care clinic, of whom 271 adults (71% female, 65% black) participated. Participants completed modules from the CAT-MH (Computerized Adaptive Diagnostic Test for MDD, CAT-Depression Inventory, CAT-Anxiety Inventory); brief paper questionnaires (9-item Patient Health Questionnaire [PHQ-9], 2-item Patient Health Questionnaire [PHQ-2], Generalized Anxiety Disorder 7-item Scale [GAD-7]); and a reference-standard interview, the Structured Clinical Interview for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) Diagnoses. RESULTS: On the basis of the interview, 31 participants met criteria for MDD and 29 met criteria for GAD. The diagnostic accuracy of the Computerized Adaptive Diagnostic Test for MDD (area under curve [AUC] = 0.85) was similar to that of the PHQ-9 (AUC = 0.84) and higher than that of the PHQ-2 (AUC = 0.76) for MDD screening. Using the interview as the reference standard, the accuracy of the CAT-Anxiety Inventory (AUC = 0.93) was similar to that of the GAD-7 (AUC = 0.97) for assessing anxiety severity. The patient-preferred screening method was assessment via tablet/computer with audio. CONCLUSIONS: Computerized adaptive testing could be a valid and efficient patient-centered screening strategy for depression and anxiety screening in primary care settings.

OBJECTIVE: Technology-enabled services frequently have limited reach and suboptimal engagement when implemented in real-world settings. One reason for these implementation failures is that technology-enabled services are not designed for the users and contexts in which they will be implemented. User-centered design is an approach to designing technologies and services that is grounded in information from the stakeholders who will be using or impacted by them, and the contexts for implementation. The purpose of this article is to present user-centered design methods that can be applied to technology-enabled services for eating disorders. METHOD: We provide an overview of the user-centered design process, which is iterative and involves stakeholders throughout. One model is presented that depicts six phases of a user-centered design process: investigate, ideate, prototype, evaluate, refine and develop, and validate. RESULTS: We then review how user-centered design approaches can be applied to designing technology-enabled services for patients with eating disorders, and we integrate a hypothetical case example that demonstrates the application of these techniques to designing a technology-enabled service for binge eating. Most of the user-centered design techniques can be implemented relatively quickly, allowing us to rapidly learn what stakeholders want and to identify problems before devoting time and resources to developing and delivering technologies and services. DISCUSSION: Through this work, we show how designing services that fit into the patterns and routines that stakeholders already are doing can ensure that services are relevant to stakeholders and meet their needs, potentially improving engagement and clinical impact. RESUMEN: Los servicios habilitados tecnológicamente frecuentemente tienen un alcance limitado y un involucramiento subóptimo cuando son implementados en escenarios del mundo real. Una razón para estas fallas de implementación es que los servicios habilitados tecnológicamente no están diseñados para los usuarios y contextos en los que serán implementados. El diseño centrado en el usuario es un abordaje para diseñar tecnologías y servicios que está basado en información de las partes interesadas que estarán haciendo uso o impactados por ellos, y los contextos para implementación. El propósito de este estudio es presentar métodos de diseños centrados en el usuario que pueden ser aplicados a servicios habilitados tecnológicamente para trastornos de la conducta alimentaria. Ofrecemos una visión general del proceso de diseño centrado en el usuario, que es iterative e involucra a las partes interesadas a lo largo de todo el proceso. Hemos presentado un modelo que describe seis fases de un proceso de diseño centrado en el usuario: investigar, idear, crear prototipos, evaluar, refinar y desarrollar, y validar. Luego revisamos cómo estos abordajes de diseño centrado en el usuario pueden ser aplicados para diseñar servicios habilitados tecnológicamente para pacientes con trastornos de la conducta alimentaria, e integramos un ejemplo de caso hipotético que demuestra la aplicación de estas técnicas para diseñar un servicio habilitado tecnológicamente para comer en atracones. Muchas de las técnicas de diseño centrado en el usuario pueden ser implementadas relativamente rápido, lo que nos permite aprender rápidamente lo que las partes interesadas quieren e identificar los problemas antes de dedicarles tiempo y recursos al desarrollo y entrega de tecnologías y servicios. A través de este trabajo, mostramos cómo el diseño de servicios que se ajustan a los patrones y rutinas que las partes interesadas ya están haciendo puede garantizar que los servicios sean relevantes para los interesados y que satisfagan sus necesidades, lo que podría mejorar la participación y el impacto clínico.
