Prospective 2-Year Course and Predictors of Outcome in Avoidant/Restrictive Food Intake Disorder

To evaluate the 2-year course and outcomes of full and subthreshold avoidant/restrictive food intake disorder (ARFID) in youth aged 9 to 23 at baseline using a prospective longitudinal design to characterize the remission and persistence of ARFID, evaluate diagnostic crossover, and identify predictors of outcome. Greater severity in each ARFID profile-sensory sensitivity, fear of aversive consequences, and lack of interest-was hypothesized to predict greater likelihood of illness persistence, controlling for age, sex, body mass index percentile, ARFID treatment status, and baseline diagnosis. Participants (N= 100; age range, 9-23 years; 49% female; 91% White) were followed over 2 years. The Pica, ARFID, and Rumination Disorder Interview was used across 3 time points (baseline, year 1, year 2) to measure the severity of each ARFID profile and evaluate illness persistence or remission, and the Eating Disorder Assessment for DSM-5 was used to evaluate diagnostic crossover. Across the 2-year follow-up period, half the participants persisted with their original diagnosis, and 3% of participants experienced a diagnostic shift to anorexia nervosa. Greater severity in the sensory sensitivity and lack of interest profiles was associated with higher likelihood of ARFID persistence at year 1 only; greater severity in the fear of aversive consequences profile was associated with higher likelihood of ARFID remission at year 2 only. Findings underscore the distinctiveness of ARFID from other eating disorders and emphasize its persistence over 2 years. Results also highlight the predictive validity and prognostic value of ARFID profiles (ie, sensory sensitivity, fear of aversive consequences, lack of interest).

The need for more inclusive measurement to advance equity in eating disorders prevention

ABSTRACT Eating disorder (ED) research and practice have been shaped by prevailing stereotypes about who EDs are most likely to affect. Subsequently, the field has prioritized the needs and concerns of affluent, cisgender, heterosexual, white girls and women to the exclusion of others, especially people marginalized based on their race, ethnicity, sexual orientation, and/or gender identity. However, EDs exist across diverse groups and actually occur with elevated prevalence in several marginalized groups. Growing research points to differences in the drivers of EDs in such groups (e.g. desire to attain the curvy rather than thin ideal; dietary restraint due to food insecurity rather than weight/shape concerns), yet tools typically used for screening and intervention evaluation do not capture eating pathology driven by such factors. In this commentary, we describe gaps in existing ED assessment tools and argue these gaps likely underestimate EDs among marginalized groups, bias who is invited, participates in, and benefits from ED prevention programs, and obscure potential group differences in the efficacy of such programs. We also discuss the potential of these ramifications to exacerbate inequities in EDs. Finally, we outline recommendations to overcome existing gaps in measurement and, consequently, advance equity in the realm of ED prevention.

Weight suppression at lowest weight as an indicator of eating disorder clinical severity: A retrospective cohort study

ObjectivesWeight suppression (WS) defines the difference between the highest weight in adulthood and the current weight. WS at lowest weight is the difference between the highest and the lowest ever weight. Weight rebound is the difference between the past lowest weight and current weight. The distinction in the capacities of WS, weight rebound, and WS at the lowest weight remains unclear regarding their efficacy in forecasting clinical endpoints. This study assessed the relationship between WS, WS at lowest weight and/or weight rebound and eating disorder (ED) clinical severity. MethodsIn this retrospective cohort study, adult participants were selected at the Outpatient Unit for multidisciplinary assessment of ED, Montpellier, France, between February 2012 and October 2014 and May 2017 and January 2020. ED clinical severity was evaluated using the Eating Disorder Examination Questionnaire (EDE-Q). ResultsThe sample included 303 patients: 204 with anorexia nervosa (AN) and 99 with bulimia nervosa (BN). The EDE-Q total score was positively correlated with WS at lowest weight in patients with AN (Spearman's rho = 0.181, p = 0.015) and with BN (Spearman's rho = 0.377; p < 0.001). It was also positively correlated with weight rebound (Spearman's rho = 0.319; p = 0.003) in patients with BN. In the multivariate analysis, EDE-Q total score was associated with WS at lowest weight only in patients with BN (β = 0.265; p = 0.03). ConclusionWS at lowest weight seems to be a good measure of ED clinical severity. More research is needed for better understanding WS at lowest weight in assessment and treatment of patients with ED.

Digital health applications for eating disorders treatment

Eating disorders (EDs) are characterized by multifaceted etiologies, difficulties in accessing care (especially in regional locations), and variable responsiveness to treatments. Digital technologies are viewed as an important innovation in the assessment and treatment of EDs. We discuss current implementation of these innovations as well as important future directions for the field.

Eating disorders associated with polycystic ovary syndrome, a literature review

Polycystic Ovary Syndrome (PCOS) is a common enigmatic, heterogenous endocrine disorder with multisystem consequences affecting women at reproductive age. Most associated dysfunctions in PCOS patients include ovarian dysmorphology, hormonal imbalances, metabolic disturbances, and neuropsychological impairments. Emerging studies have shown a relationship between women with PCOS and eating disorders (ED). ED is described as a psychological disorder characterized by extreme and constant disruptions in eating behaviors that can negatively impact one’s mental health and status. Types of EDs include binge eating disorder (BED), bulimia nervosa (BN), anorexia nervosa (AN), other specified feeding or eating disorders (OSFED), and unspecified feeding and eating disorders (UFED). Understanding the clinical relevance of these associations and adding correct assessments of ED as a key determinant of eating behavior may contribute to the successful treatment of women with PCOS. Thus, this review aims to outline a more profound connection between the involvement of multiple eating disorders and related disordered eating in women with PCOS; it also establishes a wider overview regarding the prevalence of comorbidities in eating disorders. Furthermore, the majority of researchers advised that screening for eating disorders, PCOS phenotyping, and neuroimaging modalities can be utilized to provide a better health outcome in PCOS patients.

Virtually possible: strategies for using telehealth in eating disorder treatment learned from the COVID-19 pandemic

ABSTRACT The COVID-19 pandemic resulted in an abrupt shift from in-person to virtual treatment, and clinicians continue to offer telehealth due to its advantages. Telehealth may be a viable, effective, and safe treatment modality for many clients with eating disorders. We consider contemporary issues regarding the use of telehealth in eating disorder treatment and identify strategies to enhance its delivery. First, we emphasize key factors when choosing therapy delivery (telehealth, in-person, or hybrid). Second, we address telehealth-specific planning, preparation, safety, and privacy considerations. Third, we discuss how eating disorder assessment and evidence-based interventions can be adapted for telehealth delivery. Fourth, we raise telehealth-specific challenges related to group-based delivery and the therapeutic alliance offering alternative avenues for connection and engagement. We conclude with a discussion of how additional research is needed to refine the presented strategies, develop new strategies, and assess their efficacy and effectiveness.

Advancing the Assessment and Treatment of Comorbid Pediatric Chronic Functional Abdominal Pain (CFAP) and Restrictive Eating Disorders.

The aim of this review is to heighten awareness of the association between chronic functional abdominal pain (CFAP) and restrictive eating disorders (ED) in adolescents. We describe current diagnostic practices and propose future research efforts to improve the assessment and treatment of comorbid CFAP and restrictive EDs. A narrative review of the literature on CFAP and EDs was performed using PubMed, JSTOR, ScienceDirect, and PsycINFO and the following search terms: 'restrictive eating disorders', 'chronic functional abdominal pain', 'chronic pain' 'treatment' 'diagnosis' and 'adolescents'. Published studies on restrictive EDs and CFAP from May 2008 to March 2023 were included. Ascribable to the overlap in etiology and symptom presentation, adolescents with chronic pain are significantly less likely to have their ED pathology promptly identified by providers compared to adolescents without comorbid chronic pain. This highlights the importance of the time sensitive and accurate identification of EDs in adolescents with CFAP. Overall, assessment methods are limited and EDs take longer to be identified in adolescents with comorbid CFAP. Future efforts should address diagnostic practices in pediatric settings and improve the communication among medical and mental health providers in order to promote the rapid and effective diagnosis and treatment of comorbid CFAP and EDs.

Estimated prevalence of DSM-5 eating disorders in Norwegian adolescents: A community based two-phase study.

Little is known about the prevalence of DSM-5 eating disorders (EDs) in adolescents. In Norway, the most recent community-based prevalence study in adolescents was published more than 20 years ago. The aim of this study was to assess the prevalence of DSM-5 EDs in Norwegian adolescents using a two-phase design. A total of 1558 upper secondary school students (827 girls and 730 boys) (ages 16-19) were screened for at-risk ED pathology using the Eating Disorder Examination-Questionnaire short version (EDE-QS). A sub-sample of 99 adolescents (87 girls and 12 boys) subsequently participated in a clinical interview using the Eating Disorder Assessment for DSM-5 (EDA-5). Eating pathology was common, with 19.9% of participants scoring at or above the applied EDE-QS cut-off. The estimated prevalence of any ED was 9.4% in the total sample, and 16.4% in girls. The number of boys who took part in the diagnostic interview was low, thus, diagnostic data from boys were not analyzed separately. Prevalence estimates of AN, BN, BED, and OSFED in girls were 2.7%, 1.1%, 1.9%, and 10.7%. Atypical AN was the most frequently assigned diagnosis in girls. Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth. In this study, 1558 adolescents, aged 16-19, were screened for ED pathology. A subsample completed a diagnostic interview using DSM-5 criteria. Results showed that one in five adolescents displayed problematic eating behaviors and cognitions. The estimated prevalence rate of any ED was 9.4%. Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.

Differences in Telomere Length between Adolescent Females with Anorexia Nervosa Restricting Type and Anorexia Nervosa Binge-Purge Type.

Physiological and psychological distress may accelerate cellular aging, manifested by shortening of telomere length (TL). The present study focused on TL shortening in anorexia nervosa (AN), an illness combining physiological and psychological distress. For that purpose, we measured TL in 44 female adolescents with AN at admission to inpatient treatment, in a subset of 18 patients also at discharge, and in 22 controls. No differences in TL were found between patients with AN and controls. At admission, patients with AN-binge/purge type (AN-B/P; n = 18) showed shorter TL compared with patients with AN-restricting type (AN-R; n = 26). No change in TL was found from admission to discharge, despite an improvement in body mass index standard deviation score (BMI-SDS) following inpatient treatment. Older age was the only parameter assessed to be correlated with greater TL shortening. Several methodological changes have to be undertaken to better understand the putative association of shorter TL with B/P behaviors, including increasing the sample size and the assessment of the relevant pathological eating disorder (ED) and non-ED psychological correlates in the two AN subtypes.

Psychometric properties of the Parent Eating Disorder Examination Questionnaire.

To examine the psychometric properties of the Parent Eating Disorder Examination Questionnaire (PEDE-Q), developed to improve eating disorder (ED) assessment among youth by including parents as informants. A multi-site, transdiagnostic sample of 355 adolescents with EDs completed the Eating Disorder Examination Questionnaire (EDE-Q) and their parents completed the PEDE-Q. The internal consistencies of the PEDE-Q subscales were on par with established EDE-Q ranges (.73 to .90), both when examined using the original four-factor EDE-Q subscales and the seven-item, three-factor subscales of the brief EDE-Q. Statistically significant medium- to large-sized correlations and poor to moderate levels of agreement were found between the corresponding EDE-Q and PEDE-Q subscales. Receiver-operator characteristic (ROC) curves showed that the PEDE-Q had a statistically significant area under the curve (AUC) to maximize sensitivity and specificity in diagnosing full-syndrome AN, whereas the EDE-Q did not. Based on chi-square analyses, the PEDE-Q identified a statistically significantly greater number of AN cases than the EDE-Q. The EDE-Q yielded a BN diagnosis more frequently than the PEDE-Q, although this difference was not statistically significant. Results suggest that the PEDE-Q has good psychometric properties and provides incremental information that can aid in the assessment and diagnosis of adolescents with EDs, particularly those with AN. There exist complex challenges to identifying clinically significant eating disorders among youth. The PEDE-Q is a questionnaire measure that improves eating disorder assessment among children and adolescents by asking parents to report on the symptoms and behaviors they have observed in their child and that youth may not fully disclose. The PEDE-Q can aid in the diagnosis of adolescents with eating disorders, particularly those with anorexia nervosa.

Investigating the factor structure and measurement invariance of the Eating Disorder Examination-Questionnaire (EDE-Q) in a community sample of gender minority adults from the United States.

The Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report assessments of eating disorder symptoms. However, evidence indicates potential problems with its original factor structure and associated psychometric properties in a variety of populations, including gender minority populations. The aim of the current investigation was to explore several previously published EDE-Q factor structures and to examine internal consistency and measurement invariance of the best-fitting EDE-Q model in a large community sample of gender minority adults. Data were drawn from 1567 adults (337 transgender men, 180 transgender women, and 1050 gender-expansive individuals) who participated in The PRIDE Study, a large-scale longitudinal cohort study of sexual and gender minorities from the United States. A series of confirmatory factor analyses (CFAs) were conducted to explore the fit of eight proposed EDE-Q models; internal consistency (Cronbach's alphas, Omega coefficients) and measurement invariance (multi-group CFA) were subsequently evaluated. A brief seven-item, three-factor (dietary restraint, shape/weight overvaluation, body dissatisfaction) model of the EDE-Q consistently evidenced the best fit across gender minority groups (transgender men, transgender women, gender-expansive individuals). The internal consistencies of the three subscales were adequate in all groups, and measurement invariance across the groups was supported. Taken together, these findings support the use of the seven-item, three-factor version of the EDE-Q for assessing eating disorder symptomatology in gender minority populations. Future studies can confirm the current findings in focused examinations of the seven-item, three-factor EDE-Q in diverse gender minority samples across race, ethnicity, socioeconomic status, and age ranges. Although transgender individuals have greater risk of developing an eating disorder, the factor structure of the Eating Disorder Examination-Questionnaire, one of the most widely used eating disorder assessment measures, has not been explored in transgender adults. We found that a seven-item model including three factors of dietary restraint, shape and weight overvaluation, and body dissatisfaction had the best fit among transgender and nonbinary adults.

Beyond Binge Eating: The Impact of Implicit Biases in Healthcare on Youth with Disordered Eating and Obesity.

(1) Background: Obesity and eating disorders (ED) can coexist resulting in worse health outcomes. Youth with ED are more likely to have obesity relative to peers with a healthy weight. Pediatric providers deliver first-line care to children and youth of all sizes and body shapes from infancy to adolescents. As healthcare providers (HCPs), we bring biases into our practice. Learning to recognize and address these biases is needed to provide the best care for youth with obesity. (2) Purpose: This paper aims to summarize the literature regarding the prevalence of ED beyond binge eating in youth with obesity and discuss how the intersection of weight, gender, and racial biases impact the assessment, diagnosis, and treatment of ED. We provide recommendations for practice and considerations for research and policy. (3) Conclusions: The assessment and treatment of ED and disordered eating behaviors (DEBs) in youth with obesity is complex and requires a holistic approach. This approach begins with identifying and understanding how one's implicit biases impact care. Providing care from a patient-centers lens, which considers how the intersection of multiple stigmatized identities increases the risk for DEBs in youth with obesity may improve long-term health outcomes.

Eating disorder mental health literacy: A national survey of clinical social workers in the United States

Summary Social workers’ eating disorder mental health literacy (ED-MHL) is essential to the detection, assessment, and treatment of eating disorders (EDs) and disordered eating (DE) in clinical practice. This study explored social workers’ ED-MHL, particularly the assessment practices of EDs on intake forms, and within the first two therapy sessions. Participants in this national survey were N = 316 outpatient masters-level social workers in the United States. Participants completed an online survey measuring ED assessment practices in clinical practice. Findings Results showed that 42.4% ( n = 133) of respondents did not routinely assess for EDs/DE on clinical intake forms, and 53.2% ( n = 165) did not assess within the first two therapy sessions. However, those with recent training related to EDs were more likely to assess. Participants reported low to moderate perceived comfort levels with the assessment of EDs, and training and education were identified as needed resources. Social workers reported deficits in their own assessment practices of EDs. Barriers included: lack of training about EDs/DE; uncertainty about process questions to ask; and perceptions that EDs/DE are rarely the client's primary presenting problem. Applications Difficulties with detection and screening practices appeared contingent on gaps in existing education and training related to EDs/DE. These findings suggest that future research may serve to increase social workers’ ED-MHL, as underscored by the noteworthy finding that 86.1% ( n = 229) of the sample reported that they would make proactive changes in their clinical practice, as a direct result of participating in this study.

Strengths and weaknesses of the German translation of the Inflexible Eating Questionnaire and of eating disorder assessment in general.

The present article introduces the German translation of the Inflexible Eating Questionnaire (IEQ-G), performs a psychometric evaluation, and explores the relationship of Inflexible Eating to the subscales of the Eating Disorder Examination-Questionnaire (EDE-Q) and Obsessive-Compulsive (OC) symptoms. The cross-sectional study was carried out in the German-speaking area. A paper and pencil survey was completed by 612 females and 442 males of the general population. SEM analyses showed that the IEQ-G allows for calculating a total score and invariance tests were mostly promising. As a side result, the original 4-factorial structure of the EDE-Q could not be replicated, but a 3 dimensional solution proved convincing. From a psychometric point of view, the IEQ-G outperformed the EDE-Q. On a latent level, Inflexible Eating was remarkably strong related to OC-symptoms and the EDE-Q subscales. The detail analyses revealed that Eating Disorder assessment in general lacks subgroup-specific aspects, for instance, regarding gender or dietary preferences, important for early diagnosis and screening of ED. The IEQ-G proved applicable in a German speaking adult population and recommends itself for cross-cultural studies.

Association of the COVID-19 Pandemic With Adolescent and Young Adult Eating Disorder Care Volume

The COVID-19 pandemic has affected youth mental health. Increases in site-specific eating disorder (ED) care have been documented; however, multisite studies demonstrating national trends are lacking. To compare the number of adolescent/young adult patients seeking inpatient and outpatient ED care before and after onset of the COVID-19 pandemic. Using an observational case series design, changes in volume in inpatient and outpatient ED-related care across 15 member sites (14 geographically diverse hospital-based adolescent medicine programs and 1 nonhospital-based ED program) of the US National Eating Disorder Quality Improvement Collaborative was examined. Sites reported monthly volumes of patients seeking inpatient and outpatient ED care between January 2018 and December 2021. Patient volumes pre- and postpandemic onset were compared separately for inpatient and outpatient settings. Demographic data such as race and ethnicity were not collected because this study used monthly summary data. Onset of the COVID-19 pandemic. Monthly number of patients seeking inpatient/outpatient ED-related care. Aggregate total inpatient ED admissions were 81 in January 2018 and 109 in February 2020. Aggregate total new outpatient assessments were 195 in January 2018 and 254 in February 2020. Before the COVID-19 pandemic, the relative number of pooled inpatient ED admissions were increasing over time by 0.7% per month (95% CI, 0.2%-1.3%). After onset of the pandemic, there was a significant increase in admissions over time of 7.2% per month (95% CI, 4.8%-9.7%) through April 2021, then a decrease of 3.6% per month (95% CI, -6.0% to -1.1%) through December 2021. Prepandemic, pooled data showed relative outpatient ED assessment volume was stable over time, with an immediate 39.7% decline (95% CI, -50.4% to -26.7%) in April 2020. Subsequently, new assessments increased by 8.1% (95% CI, 5.3%-11.1%) per month through April 2021, then decreased by 1.5% per month (95% CI, -3.6% to 0.7%) through December 2021. The nonhospital-based ED program did not demonstrate a significant increase in the absolute number of admissions after onset of the pandemic but did see a significant increase of 8.2 (95% CI, 6.2-10.2) additional inquiries for care per month in the first year after onset of the pandemic. In this study, there was a significant COVID-19 pandemic-related increase in both inpatient and outpatient volume of patients with EDs across sites, particularly in the first year of the pandemic. Given inadequate ED care availability prior to the pandemic, the increased postpandemic demand will likely outstrip available resources. Results highlight the need to address ED workforce and program capacity issues as well as improve ED prevention strategies.

4 The Impact of the COVID-19 Pandemic on Number and Severity of New Diagnoses of Restrictive Eating Disorders During Prolonged Lockdown in Ontario, Canada

Abstract Background The coronavirus disease 2019 (COVID-19) pandemic has had a disproportionate impact on the well-being of adolescents and young adults. Worldwide, eating disorder (ED) experts have observed worsening symptoms in youth with pre-existing EDs and an escalation in the number of new cases compared to prior years. Disruption of routine, work and school closures, as well as social isolation are potential contributing factors. The Canadian province of Ontario (specifically the most highly populated cities) experienced one of the most prolonged lock downs worldwide with approximately 20 weeks of face-to-face school closure and/or restriction to virtual learning. Objectives We sought to better understand the impact of COVID-19 on new pediatric ED presentations, patient characteristics and hospital admissions in a tertiary care Children’s Hospital. Design/Methods We completed a retrospective chart review of patients presenting for new ED assessments at a single centre pediatric ED program within a tertiary care children’s hospital between January 1st, 2015 and June 1st 2021. Patients aged 9-18 years old with a new diagnosis of Anorexia Nervosa (AN) restrictive type or binge/purge type or Other Specified Feeding and Eating Disorder (OSFED) - Atypical Anorexia Nervosa (AAN) were included. Demographic and clinical variables for pre and post pandemic were analyzed using Chi-Square and T-Tests. Interrupted time series regression was used to examine pre-pandemic and post-pandemic monthly summary data over time. Results Overall, 425 youth were newly diagnosed with AN or AAN (N=329 pre-pandemic, N=96 pandemic) during the study period (Jan 1 2015 – December 31 2020). Average age was 14.7 years (SD 1.8, range 8.1 – 17.9). Most youth were diagnosed with DSM-5 AN-restrictive type (65.6%). The number of new diagnoses of AN and AAN during the pandemic more than doubled when compared to pre-pandemic years. In the 5-year period preceding the pandemic, mean number of newly diagnosed cases was 5.1/month (ßcoeff=0.043, p=0.33), increasing to 10.6/month (p=&amp;lt;0.001) during the pandemic and demonstrating an upward trend coinciding with onset of lockdown measures (ßcoeff=5.95, p&amp;lt;0.001). At the time of initial assessment, more youth presented with medical instability and increased illness severity. Hospitalization increased from an average of 2.2/month to 6.3/month (ßcoeff -0.008 vs. 3.23, p&amp;lt;0.0001). Average heart rate also decreased from 58.6 bpm (SD 16.6) pre-pandemic to 53.3 bpm (SD 16.3), p&amp;lt;0.008. Conclusion With this study, we found a significant increase in both new diagnoses and admissions for medical instability for AN and AAN among youth at our institution during the COVID-19 pandemic. Our study contributes to the growing body of global evidence tracking the unanticipated surge of eating disorder diagnoses and severity in already under-resourced health systems. It is unclear how long the effects of the pandemic may last. Further research is required to better understand the illness trajectory and treatment outcomes of pandemic-triggered EDs in adolescents.

Design and methods of the Longitudinal Eating Disorders Assessment Project research consortium for veterans.

Military service members must maintain a certain body mass index and body fat percentage. Due to weight-loss pressures, some service members may resort to unhealthy behaviors that place them at risk for the development of an eating disorder (ED). To understand the scope and impact of EDs in military service members and veterans, we formed the Longitudinal Eating Disorders Assessment Project (LEAP) Consortium. LEAP aims to develop novel screening, assessment, classification, and treatment tools for veterans and military members with a focus on EDs and internalizing psychopathology. We recruited two independent nationally representative samples of post-9/11 veterans who were separated from service within the past year. Study 1 was a four-wave longitudinal survey and Study 2 was a mixed-methods study that included surveys, structured-clinical interviews, and qualitative interviews. Recruitment samples were representative of the full population of recently separated veterans. Sample weights were created to adjust for sources of non-response bias to the baseline survey. Attrition was low relative to past studies of this population, with only (younger) age predicting attrition at 1-week follow-up. We expect that the LEAP Consortium data will contribute to improved information about EDs in veterans, a serious and understudied problem.

The structure of eating disorder and somatic symptoms

Individuals with eating disorders (EDs) often present with somatic concerns in treatment, such as bloating, fullness, and feeling tight clothes on skin. However, most research generally focuses on general interoception (e.g., heartbeat) rather than sensations relevant to EDs (e.g., sensations related to the gastrointestinal system or body movement). In the current study (N = 181), we used network analysis to model the structure of ED symptoms and somatic concerns among individuals with anorexia nervosa, bulimia nervosa, and other specified feeding and eating disorder. Results showed that heightened sensitivity to somatic concerns had the highest strength centrality within a symptom network comprising ED and somatic symptoms. Exploratory graph analysis identified four symptom dimensions: cognitive-affective ED symptoms, behavioral ED symptoms, general interoception, and ED-specific proprioception. Findings suggest that heightened sensitivity to somatic concerns may maintain ED symptoms and mutually reinforce other somatic concerns. Implications concerning assessment and treatment of EDs are discussed.

A Pilot, Time-Series Investigation of Depression, Anxiety, and Eating Disorder Symptoms in Adults Experiencing Major Depressive Symptoms: The Need for Eating Disorder Assessment and Research in Depression

Major Depressive Disorder (MDD) is a prevalent psychiatric disorder impacting 10-16% of Americans in their lifetime. Approximately 60% of individuals with MDD have comorbid anxiety disorders. Additionally, although scarce research has examined eating disorders (EDs) in depression, a bidirectional association exists between ED and MDD symptoms. The current pilot study (N = 31 individuals with moderate to severe depression) modeled networks of depressive, anxiety, and ED symptoms using intensive time-series data. This study also tested if temporal central symptoms predicted six-month clinical outcomes. The most central symptoms were guilt, self-dislike, lack of energy, and difficulty concentrating. Several anxiety and ED symptoms were also central, including physical anxiety, social anxiety, body dissatisfaction, and desire for thinness. The central symptom crying predicted six-month depression with a medium effect size. These findings suggest anxiety and ED symptoms may influence the day-to-day course of depression in some individuals with comorbid diagnoses, but predictors of symptoms across hours may differ from predictors across longer time scales (i.e., months). Time scale should be considered when conducting and interpreting research on MDD. Research, assessment, and treatment for MDD should continue to explore transdiagnostic approaches including anxiety and ED symptoms to optimize care for individuals with complex presentations.

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

ObjectiveThis review aimed to examine the validity of self‐report screening questionnaires for identifying eating disorder (ED) risk in adults and adolescents with overweight/obesity.MethodFive 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).ResultsTwenty‐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.DiscussionQuestionnaires 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 SignificanceIndividuals 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.
