RESUMO
OBJECTIVE: Only approximately 20% of college students with an eating disorder (ED) seek treatment. One barrier to seeking treatment is weight discrimination. Past research demonstrates that experiencing weight discrimination is associated with increased ED risk and decreased in-person treatment engagement. Weight discrimination may be a particularly relevant treatment barrier for students who have a higher body weight given their higher likelihood of experiencing weight discrimination. METHODS: College students with a probable ED diagnosis (N = 372; Mage = 23.94; 73.12% women, 18.55% men, 6.18% another gender; 11.29% Asian, 4.57% Black, 12.63% Hispanic, 83.60% White, 4.84% Native American, and 0.54% another race) completed an online self-report survey that included the Clinical Impairment Assessment (CIA), Experience of Weight Discrimination (EWD) Scale, and a 0-100 scale to indicate interest in participating in virtual guided self-help ED treatment. RESULTS: Linear regression showed significant positive relationships between weight discrimination and ED-related psychiatric impairment and treatment interest. DISCUSSION: Elevations in CIA scores corroborate past literature that suggested that weight discrimination was positively related to ED psychopathology. Contrary to past research, college students who experienced weight discrimination had greater treatment interest. Students who experience weight discrimination may view virtual self-guided treatment as less weight-stigmatizing due to the "do-it-yourself" approach and no in-person interactions. Findings highlight the potential impacts of weight discrimination on acceptability of ED-related care. Future research is needed to identify ways to reduce weight discrimination and promote weight-inclusive practices in the medical system.
RESUMO
PURPOSE: Researchers have theorized that interactions between appetitive and circadian disruptions result in increased eating disorder (ED) symptoms and insomnia. However, it is unclear how specific insomnia symptoms present among people with EDs and if the latent structure of insomnia in this population is similar to that of people with insomnia disorder. METHODS: We conducted a secondary analysis of data collected on ED and insomnia symptoms using a subset of students (N = 547; 79.52% female) with probable EDs at a large Midwestern American university. Item response theory (IRT) for polytomous items was performed to identify item difficulty, discrimination, and information parameters for the Insomnia Severity Index (ISI). IRT parameters were compared to those established in a 2011 study of people diagnosed with insomnia disorder by Morin and colleagues. RESULTS: Clinically significant insomnia symptoms were common among students with ED pathology and symptom endorsement for each ISI item ranged from 40.77 to 86.65%. ISI items assessing insomnia-related impairment and distress showed better discriminative capacities and had higher item information than items assessing sleep behavior alterations (i.e., difficulties falling asleep, difficulties maintaining sleep, waking too early). Item discrimination was largely similar among the ED sample compared to previous IRT analyses in an insomnia disorder sample. CONCLUSION: Insomnia symptoms are common among university students with probable EDs and similar to those reported by people with insomnia disorder. When considering insomnia assessment, items assessing sleep behaviors alone are likely inadequate to provide information about insomnia severity among people with EDs. LEVEL V: Evidence obtained from a cross-sectional descriptive study.

OBJECTIVE: The association between eating disorders (EDs) and harmful substance use (substance use that causes psychosocial impairment) is well recognized in the literature, and military veterans may be at heightened risk for both issues due to deployment-related stressors. However, little is known about which ED-related symptoms are associated with harmful substance use in veterans, and whether gender plays a differential role in this relationship. Our aims were to: (1) examine gender differences in ED-related symptoms; and (2) examine whether ED-related symptoms differentially predict harmful substance use in US veteran men and women who had recently separated from service. METHOD: This study was based on a nationally representative four-wave longitudinal sample of post-9/11 veterans (N = 835; 61.2% female). Longitudinal mixed modeling was used to test whether specific ED-related behaviors at baseline predicted harmful substance use at follow-ups. RESULTS: We replicated gendered patterns of ED-related symptoms observed in civilian populations, wherein men had higher weight-and-body-related concerns (including excessive exercise and muscle building) and negative attitude toward obesity, and women had higher bulimic and restricting symptoms. For women, alcohol, drug, and marijuana problems were predicted by higher bulimic symptoms, whereas for men, these problems were predicted by higher restricting symptoms. CONCLUSION: Gender played a differential role in the relationship between EDs and harmful substance use. Bulimic symptoms were the most robust predictor for harmful substance use among veteran women, whereas restricting was the most robust predictor for harmful substance use among veteran men. PUBLIC SIGNIFICANCE: The current study found that veteran women had higher bulimic symptoms (characterized by binge eating and purging) and restricting than veteran men. In women, bulimic symptoms predicted future harmful use of alcohol, marijuana, and other drugs. In contrast, veteran men had higher weight-and-body-related concerns (characterized by excessive exercise and muscle building) than veteran women. In men, restricting symptoms predicted future harmful use of alcohol, marijuana, and other drugs.

OBJECTIVE: There is a lack of consensus in defining "significant weight loss" when diagnosing atypical anorexia nervosa (atypical AN) and no guidelines exist for setting target weight (TW). The current study aimed to identify community providers' practices related to the diagnosis of atypical AN and the determination of TW. A secondary aim was to evaluate whether professional discipline impacted "significant weight loss" definitions. METHOD: A variety of providers (N = 141; 96.4% female) completed an online survey pertaining to diagnostic and treatment practices with atypical AN. Descriptive statistics were computed to characterize provider-based practices and Fisher's exact tests were used to test for differences in diagnostic practices by professional discipline. Thematic analysis was used to examine open-ended questions. RESULTS: Most (63.97%) providers diagnosed atypical AN in the absence of any weight loss if other AN criteria were met, but doctoral-level psychologists and medical professionals were less likely to do so compared to nutritional or other mental health professionals. Most providers found weight gain was only sometimes necessary for atypical AN recovery. Qualitative responses revealed providers found atypical AN to be a stigmatizing label that was not taken seriously. Providers preferred to use an individualized approach focused on behaviors, rather than weight when diagnosing and treating atypical AN. DISCUSSION: Lack of diagnostic clarity and concrete treatment guidelines for atypical AN may result in substantial deviations from the DSM-5-TR criteria in real-world practice. Clinically useful diagnostic definitions for restrictive eating disorders and evidence-based treatment guidelines for TW and/or other relevant recovery metrics are needed. PUBLIC SIGNIFICANCE: The current study found variability in how community providers diagnose and determine target recovery weight for atypical anorexia nervosa (atypical AN). Many providers viewed the diagnosis of atypical AN as stigmatizing and preferred to focus on behaviors, rather than weight. This study underscores the importance of creating a clinically useful diagnostic definition and guidelines for recovery for atypical AN backed by empirical evidence that providers may implement in practice.

OBJECTIVE: Social stigma has been associated with disparities in sleep heath; however, one type of stigma that has been less evaluated is weight bias internalization. Previous studies have shown inconsistent results linking weight bias internalization and sleep problems and few have examined associations with insomnia. METHODS: Women with disordered eating (N = 173, Mage=20.22, SD=1.70, range=18-25) completed questionnaires measuring insomnia symptoms, weight bias internalization, alcohol use, and dysphoria. Linear regression tested associations between weight bias internalization and insomnia symptom severity, after adjusting for demographic variables, alcohol use, and dysphoria. RESULTS: Weight bias internalization, alcohol use, and dysphoria were significantly positively associated with insomnia symptom severity above-and-beyond demographic variables. CONCLUSIONS: Although effect sizes were small, weight bias internalization was associated with greater insomnia symptom severity. Results add to the growing literature examining the associations of stigma with sleep health.

OBJECTIVES: Restrictive eating disorders (EDs) occur across the weight spectrum, but historically more focus has been given to anorexia nervosa (AN) than atypical anorexia nervosa (atypAN). AtypAN's relegation to a diagnosis in the "other specified feeding and eating disorder" (OSFED) category and paucity of research surrounding atypAN invariably implies a less clinically severe ED. However, a growing body of research has begun to question the assumption that atypAN is less severe than AN. The current review and meta-analysis aimed to provide a comprehensive review to compare atypAN and AN on measures of eating disorder psychopathology, impairment, and symptom frequency to test whether atypAN is truly less clinically severe than AN. METHODS: Twenty articles that reported on atypAN and AN for at least one of the variables of interest were retrieved from PsycInfo, PubMed, and ProQuest. RESULTS: For eating-disorder psychopathology, results indicated that differences were nonsignificant for most indicators; however, atypAN was associated with significantly higher shape concern, weight concern, drive for thinness, body dissatisfaction, and overall eating-disorder psychopathology than AN. Results indicated that atypAN and AN did not significantly differ on clinical impairment or the frequency of inappropriate compensatory behaviors, whereas there was a significantly higher frequency of objective binge episodes in AN (vs. atypAN). DISCUSSION: Overall, findings indicated that, in contrast to the current classification system, atypAN and AN were not clinically distinct. Results underscore the need for equal access to treatment and equal insurance coverage for restrictive EDs across the weight spectrum. PUBLIC SIGNIFICANCE: The current meta-analysis found that atypAN was associated with higher drive for thinness, body dissatisfaction, shape concern, weight concern, and overall eating-disorder psychopathology than AN; whereas AN was associated with higher frequency of objective binge eating. Individuals with AN and atypAN did not differ on psychiatric impairment, quality-of-life, or frequency of compensatory behaviors, highlighting the need for equal access to care for restrictive EDs across the weight spectrum.
OBJETIVO: Los trastornos alimentarios restrictivos ocurren en todo el espectro de peso, pero históricamente se ha dado más importancia a la anorexia nerviosa (AN) que a la anorexia nerviosa atípica (ANA). El hecho de relegar la anorexia nerviosa atípica a un diagnóstico en la categoría de "otro trastorno de la ingestión de alimentos y de la conducta alimentaria" (OSFED) y la escasez de investigación en torno a la anorexia atípica, implica invariablemente un trastorno de la conducta alimentaria clínicamente menos grave. Sin embargo, un creciente cuerpo de investigación ha comenzado a cuestionar la suposición de que ANA es menos grave que AN. La revisión actual y el metanálisis tuvieron como objetivo proporcionar una revisión exhaustiva para comparar ANA y AN en las medidas de psicopatología de los trastornos alimentarios, el deterioro y la frecuencia de los síntomas para probar si ANA es realmente menos grave clínicamente que AN. MÉTODO: Veinte artículos que informaron sobre ANA y AN para al menos una de las variables de interés se recuperaron de PsycInfo, PubMed y ProQuest. RESULTADOS: Para la psicopatología del trastorno alimentario, los resultados indicaron que las diferencias no fueron significativas para la mayoría de los indicadores; sin embargo, ANA se asoció con una preocupación de forma significativamente mayor, preocupación por el peso, impulso por la delgadez, insatisfacción corporal y psicopatología general del trastorno alimentario que AN. Los resultados indicaron que ANA y AN no difirieron significativamente en el deterioro clínico o la frecuencia de comportamientos compensatorios inapropiados, mientras que hubo una frecuencia significativamente mayor de episodios de atracones objetivos en AN (frente a ANA). DISCUSIÓN: En general, los hallazgos indicaron que, en contraste con el sistema de clasificación actual, ANA y AN no eran clínicamente distintos. Los resultados subrayan la necesidad de un acceso equitativo al tratamiento y una cobertura de seguro igual para los trastornos de la conducta alimentaria restrictivos en todo el espectro de peso.

INTRODUCTION: Inappropriate compensatory behaviors (ICBs), including purging, restricting, and excessive exercising, are key symptoms of several eating disorders (EDs). Studies have found positive associations between trauma and ICBs, although few studies have explored mechanisms that may explain these relationships. Emotion dysregulation has been posited as a mechanism that explains associations among ICBs and trauma. Given that individuals with high neuroticism may be particularly likely to use ICBs to regulate emotions following a trauma, the purpose of this study was to test whether neuroticism moderated the relationship between trauma-related symptoms and each type of ICB (purging, restricting, and excessive exercise). METHOD: A community sample of adults with a DSM-5 ED (N = 263; 83.7 % female) completed measures of trauma-related symptoms, ED psychopathology, and personality. RESULTS: Zero-inflated negative binomial models revealed that trauma-related symptoms alone predicted restricting and purging behavior. In addition, we found that neuroticism alone predicted the presence of excessive exercise. We found no significant interaction between trauma-symptoms and neuroticism. CONCLUSION: Although past research has documented high rates of co-occurring ED and PTSD, the connections between trauma-related symptoms and ICBs are complex and may be unique to each type of ICB. Given that neuroticism may not influence the relationship between trauma-related symptoms and ICBs, more research should be done to establish an understanding of factors that could explain the relationship between ICBs and trauma-related symptoms. Novel interventions that simultaneously target restricting, purging, and trauma-related symptoms could be beneficial to explore.

BACKGROUND: University students are an at-risk group for the development of eating disorders (EDs); however, many college campuses lack sufficient resources to provide ED specialty care. Students report unique reasons for not seeking ED treatment, including the desire to solve the problem on their own (eg, seeking help from friends, self-medicating, or waiting to see if their problems improve), inability to afford treatment, lack of time to participate in the treatment, fear of seeing their primary care physician, and lack of recognition of their issues as an ED. Mobile health (mHealth) apps may be a cost-effective, helpful adjunctive tool to overcome personal and systemic barriers and encourage help seeking. OBJECTIVE: This paper describes the development, usability, and acceptability of the Building Healthy Eating and Self-Esteem Together for University Students (BEST-U) mHealth smartphone app, which is designed to fill critical gaps in access to ED treatment on college campuses. METHODS: We undertook a 4-phase iterative development process that focused on user-centered design. The 4 phases included needs assessment based on literature reviews, prototype development and initial evaluation in a pilot trial, redesign, and further pilot-testing to assess the usability and acceptability of the final version of the mHealth app. Acceptability and user satisfaction were assessed using an ad hoc survey that ranged from 1 (strongly disagree) to 7 (strongly agree). RESULTS: Our needs assessment identified a lack of accessible and affordable treatments for university students. To help meet this need, the BEST-U prototype was designed as an 11-week program that provided interactive, weekly modules that focused on second- and third-wave cognitive behavioral skills. The modules focused on topics such as psychoeducation, reducing thought distortions and body checking, improving body image, interpersonal effectiveness, and behavior chain analysis. The content included interactive quizzes, short answer questions, daily and weekly logs, and surveys completed in the app. BEST-U was paired with brief 25-30 minutes of weekly telehealth coaching sessions provided by a licensed provider or supervised trainee. Pilot-testing revealed minor issues with one module of the app content, which some participants viewed as having low relevance to their experience and therapist concerns about the organization of the app content. These issues were addressed through the removal, addition, and reorganization of BEST-U modules, with the help of therapists-in-training across 2 workshops. The revised version of the BEST-U app had a grand mean acceptability rating of 5.73 out of 7. The participants completed 90.1% (694/770) of the BEST-U modules, indicating high compliance. CONCLUSIONS: BEST-U is a new, acceptable, and user-friendly mHealth app to help therapists deliver brief, evidence-based cognitive behavioral interventions. Owing to its acceptability and user-friendly nature, BEST-U has high user compliance and holds promise for future implementation and dissemination in university mental health settings.
RESUMO
OBJECTIVE: Although a growing body of research has examined the impacts of ED-salient content, such as fitspiration and thinspiration, on eating disorder (ED) symptoms, there is less known about the characteristics of who may be at risk for accessing this content on Instagram. Current research is limited by cross-sectional and retrospective designs. This prospective study used ecological momentary assessment (EMA) to predict naturalistic exposure to ED-salient content on Instagram. METHODS: Female university students with disordered eating (N = 171, Mage = 20.23, SD = 1.71, range = 18-25) completed a baseline session, followed by a seven-day EMA protocol, in which they reported on Instagram use and exposure to fitspiration and thinspiration. Mixed-effects logistical regressions were used to predict exposure to ED-salient content on Instagram from four principal components (e.g., behavioral ED symptoms and trait social comparison) controlling for duration of Instagram use (i.e., dose) and day of study. RESULTS: Duration of use was positively associated with all types of exposure. Purging/cognitive restraint and excessive exercise/muscle building prospectively predicted access to any ED-salient content and fitspiration only. Restricting positively predicted thinspiration only access. Purging/cognitive restraint positively predicted accessing fitspiration and thinspiration (dual exposure). Day of study was negatively associated with any exposure, fitspiration only, and dual exposure. CONCLUSIONS: Baseline ED behaviors were differentially associated with exposure to ED-salient Instagram content; however, duration of use was also a significant predictor. Limiting use of Instagram may be important for young women with disordered eating to reduce probability of encountering ED-salient content.

OBJECTIVE: Eating disorders (EDs) are serious psychiatric disorders associated with substantial morbidity and mortality that are prevalent among university students. Because many students do not receive treatment due to lack of access on university campuses, mobile-health (mHealth) adaptations of evidence-based treatments represent an opportunity to increase treatment accessibility and engagement. The purpose of this study was to test the initial efficacy of Building Healthy Eating and Self-Esteem Together for University Students (BEST-U), which is a 10-week mHealth self-guided cognitive-behavioral therapy (CBT-gsh) app that is paired with a brief 25-30-min weekly telehealth coaching, for reducing ED psychopathology in university students. METHOD: A non-concurrent multiple-baseline design (N = 8) was used to test the efficacy of BEST-U for reducing total ED psychopathology (primary outcome), ED-related behaviors and cognitions (secondary outcomes), and ED-related clinical impairment (secondary outcome). Data were examined using visual analysis and Tau-BC effect-size calculations. RESULTS: BEST-U significantly reduced total ED psychopathology and binge eating, excessive exercise, and restriction (effect sizes ranged from -0.39 to -0.92). Although body dissatisfaction decreased, it was not significant. There were insufficient numbers of participants engaging in purging to evaluate purging outcomes. Clinical impairment significantly reduced from pre-to-post-treatment. DISCUSSION: The current study provided initial evidence that BEST-U is a potentially efficacious treatment for reducing ED symptoms and ED-related clinical impairment. Although larger-scale randomized controlled trials are needed, BEST-U may represent an innovative, scalable tool that could reach greater numbers of underserved university students than traditional intervention-delivery models. PUBLIC SIGNIFICANCE: Using a single-case experimental design, we found evidence for the initial efficacy of a mobile guided-self-help cognitive-behavioral therapy program for university students with non-low weight binge-spectrum eating disorders. Participants reported significant reductions in ED symptoms and impairment after completion of the 10-week program. Guided self-help programs show promise for filling an important need for treatment among university students with an ED.

INTRODUCTION: 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). OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: We expect that the LEAP Consortium data will contribute to improved information about EDs in veterans, a serious and understudied problem.

Given that eating disorders (EDs) are relatively common in college populations, it is important to have reliable and valid tools to identify students so that they can be referred to evidence-based care. Although research supports the psychometric properties of existing ED screens for identifying cases of EDs, most studies have been conducted in samples of young white-majority women or have not reported the psychometric properties of the screening tool in men. OBJECTIVE: The purpose of the current study was to validate a brief, 10-item screening tool for the identification of EDs-the brief assessment of stress and eating (BASE). METHOD: Participants were college students (N = 596; 68.2% cisgender women) from a large Midwestern university who completed the BASE and SCOFF. The Eating Disorders Diagnostic Survey was used to generate DSM-5 ED diagnoses. We evaluated area under the curve (AUC) for both receiver operating curves (ROC) and precision-recall curves (PRC). RESULTS: Both the BASE and SCOFF performed significantly better than chance at identifying probable EDs in cisgender women (BASE AUC: ROC = .787, PRC = .633, sensitivity = .733, specificity = .697; SCOFF AUC: ROC = .810, PRC = .684, sensitivity = .793, specificity = .701). However, the BASE (AUC: ROC = .821, PRC = .605, sensitivity = .966, specificity = .495) significantly outperformed the SCOFF (AUC: ROC = .710, PRC = .354, sensitivity = .828, specificity = .514) for identifying probable EDs in cisgender college men. DISCUSSION: The BASE is appropriate for student healthcare and college research settings. Because the BASE outperforms the SCOFF in college men, results from the current study are expected to contribute to improved identification of EDs on college campuses. PUBLIC SIGNIFICANCE: The BASE is a new screening tool to identify eating disorders. The BASE performed as well as, if not better than, the SCOFF (particularly in men). Given the need for brief, psychometrically strong, and unbiased ED screening tools in college students, the current study helps address an unmet student healthcare need that we expect will contribute to improved identification of EDs on college campuses.

OBJECTIVE: As network models of eating disorder (ED) psychopathology become increasingly popular in modeling symptom interconnectedness and identifying potential treatment targets, it is necessary to contextualize their performance against other methods of modeling ED psychopathology and to evaluate potential ways to optimize and capitalize on their use. To accomplish these goals, we used generalized network psychometrics to estimate and compare latent variable models and network models, as well as hybrid models. METHOD: We tested the structure of the Eating Pathology Symptoms Inventory (EPSI) and Eating Disorder Examination-Questionnaire (EDE-Q) in Recovery Record, Inc. mobile phone application users (N = 6856). RESULTS: Although all models fit well, results favored a hybrid latent variable and network framework, which showed that ED symptoms fit best when modeled as higher-order constructs, rather than direct symptom-to-symptom connections, and when the relationships between those constructs are described as a network. Hybrid models in which latent factors were modeled as nodes within a network showed that EPSI Purging, Binge Eating, Cognitive Restraint, Body Dissatisfaction, and Excessive Exercise had high importance in the network. EDE-Q Eating Concern and Shape Concern were also important nodes. Results showed that the EPSI network was highly stable and replicable, whereas the EDE-Q network was not. DISCUSSION: Integrating latent variable and network model frameworks enables tests of centrality to identify important latent variables, such as purging, that may promote the spread of ED psychopathology throughout a network, allowing for the identification of future treatment targets.

OBJECTIVE: There are limited data to guide the interpretation of scores on measures of eating-disorder psychopathology among underrepresented individuals. We aimed to provide norms for the Eating Disorder Examination-Questionnaire (EDE-Q) and Clinical Impairment Assessment (CIA) across racial/ethnic, gender, and sexual identities, and sexual orientations and their intersections by recruiting a diverse sample of Amazon MTurk workers (MTurkers; N = 1782). METHOD: We created a comprehensive, quantitative assessment of racial/ethnic identification, gender identification, sex assigned at birth, current sexual identification, and sexual orientation called the Demographic Assessment of Racial, Sexual, and Gender Identities (DARSGI). We calculated normative data for each demographic category response option. RESULTS: Our sample was comprised of 68% underrepresented racial/ethnic identities, 42% underrepresented gender identities, 13% underrepresented sexes, and 49% underrepresented sexual orientations. We reported means and standard deviations for each demographic category response option and, where possible, mean estimates by percentile across intersectional groups. EDE-Q Global Score for a subset of identities and intersections in the current study were higher than previously reported norms for those identities/intersections. DISCUSSION: This is the most thorough reporting of norms for the EDE-Q and CIA among racial/ethnic, sexual, and gender identities, and sexual orientations and the first reporting on multiple intersections, filling some of the gaps for commonly used measures of eating-disorder psychopathology. These norms may be used to contextualize eating-disorder psychopathology reported by underrepresented individuals. The data from the current study may help inform research on the prevention and treatment of eating-disorder psychopathology in underrepresented groups. PUBLIC SIGNIFICANCE: We provide the most thorough reporting on racial/ethnic, sexual, and gender identities, and sexual orientations for the Eating Disorder Examination - Questionnaire and Clinical Impairment Assessment, and the first reporting on intersections, which fills some of the gaps for commonly used measures of eating-disorder psychopathology. These norms help inform research on the prevention and treatment of eating-disorder psychopathology in underrepresented groups.

OBJECTIVE: The general understanding of disorders related to chronic somatic symptoms (e.g., somatic symptom disorder, functional somatic syndromes) is limited because of current categorical conceptualizations in traditional taxonomies. To improve clinical utility and validity, the Hierarchical Taxonomy of Psychopathology offers an empirically grounded dimensional approach. Therefore, the distribution of persistent somatic symptom distress observed in nature is highly relevant for informing decisions related to classification and treatment. This study analyzes the underlying structure of symptoms associated with the somatoform spectrum. METHOD: Taxometric analyses were used to examine the latent status of the somatoform spectrum, which was measured via a dimensional questionnaire devised as part of the Hierarchical Taxonomy of Psychopathology scale development effort. We generated Comparison Curve Fit Index (CCFI) profile analyses across a clinical sample of psychotherapy outpatients ( n = 487), a community sample of German adults ( n = 451), and a student sample from New Zealand ( n = 549). RESULTS: In the clinical sample (CCFI mean = 0.38) and in the student sample (CCFI mean = 0.36), a dimensional solution was clearly favored. Results in the community sample (CCFI mean = 0.51) were ambiguous. CONCLUSIONS: Across the three independent samples, qualitatively distinct subgroups within the distribution of chronic somatic symptoms could not be identified. Therefore, continuous representations seemed to best represent the structure of somatic symptoms. Implications of these findings for etiology and treatment are discussed.

OBJECTIVE: Latines have higher rates of eating disorders characterized by binge eating compared to their non-Latine white counterparts, yet culturally and socially relevant factors related to binge eating in Latines have been largely understudied. The purpose of the current study was to examine how discrimination and acculturative stress were associated with binge eating in a nationally representative sample of Latines. An additional aim was to test the extent to which family cohesion and social support could buffer against the effects of discrimination and acculturative stress on binge eating. METHOD: Participants (56% female, N = 2550) were Latines enrolled in the National Latino and Asian American Study. Structural equation modeling using 1000 re-sampled data sets built from machine learning iterative sampling procedures was used to examine the effects of discrimination, acculturative stress, family cohesion, and social support on binge eating. RESULTS: Results indicated that only discrimination was significantly associated with binge eating. Neither the direct effect of acculturative stress, interaction of family cohesion and acculturative stress, interaction of social cohesion and acculturative stress, nor the interaction of social support and discrimination were significantly associated with binge eating. DISCUSSION: This study highlights the need for mental-health providers to understand and assess discrimination among Latines presenting with concerns of binge eating. Treatments that effectively provide coping strategies to manage discriminatory experiences and reduce binge eating could improve both effectiveness of treatment and retention rates for Latine individuals with binge eating. PUBLIC SIGNIFICANCE: This study examined the association of discrimination, acculturative stress, family cohesion, and social support with binge eating in Latines. Only discrimination was significantly associated with binge eating, highlighting the importance for providers to assess discrimination among Latines with binge-eating concerns and to improve equity, inclusion, and belonging at a societal level. Modifying existing treatments to address coping with discrimination could improve the effectiveness for Latines with binge-eating concerns.

OBJECTIVE: There is ongoing discussion about whether sports participation is a risk or protective factor for eating disorders (EDs). Research is mixed, with some studies suggesting that athletes have higher mean levels of ED psychopathology compared to nonathletes, while other studies suggest the opposite effect or no differences. The purpose of the current meta-analysis was to identify whether female athletes reported higher mean levels of ED psychopathology compared to nonathletes. METHOD: Following PRISMA guidelines, we identified 56 studies that reported ED psychopathology for female athletes and nonathletes. A three-level random-effects model of between- and within-study variance was completed for the following outcome variables: overall ED psychopathology, body dissatisfaction, drive for thinness, restricting, and loss-of-control eating. RESULTS: Athletes reported lower levels of body dissatisfaction compared to nonathletes (g = -.21, p < .0001). Athletes and nonathletes reported similar levels of overall ED psychopathology, drive for thinness, restricting, and loss-of-control eating on average. Sport type significantly moderated standardized mean difference effect sizes of ED psychopathology in athletes versus nonathletes. Effect sizes comparing levels of drive for thinness, restricting, and loss-of-control eating in athletes versus nonathletes were larger for studies with athletes participating in aesthetic/lean sports compared to nonaesthetic/nonlean sports. DISCUSSION: Findings from this meta-analysis could inform future ED prevention and treatment in female athletes by providing further evidence that athletes in aesthetic/lean sports may report higher levels of ED psychopathology. Participating in nonaesthetic/nonlean sports may be a protective factor for experiencing less body dissatisfaction. PUBLIC SIGNIFICANCE STATEMENT: The current meta-analysis summarized findings from 56 studies that assessed levels of disordered eating, body dissatisfaction, dietary restricting, and loss-of-control eating in female athletes and nonathletes. Athletes reported lower levels of body dissatisfaction compared to nonathletes, highlighting that participation in sport could have some protective factors. Athletes participating in sports that require weight categories (e.g., judo) and sports that emphasize thinness/leanness (e.g., gymnastics and distance running) had higher levels of disordered eating relative to athletes participating in other types of sports that do not emphasize thinness/leanness (e.g., volleyball and basketball).
OBJETIVO: Existe un debate abierto sobre si la participación en los deportes es un factor de riesgo o protector para los trastornos de la conducta alimentaria (TCA). La investigación es mixta, con algunos estudios que sugieren que los atletas tienen niveles medios más altos de psicopatología de TCA en comparación con los no atletas, mientras que otros estudios sugieren el efecto opuesto o ninguna diferencia. El propósito del presente metanálisis fue identificar si las atletas femeninas reportaron niveles medios más altos de psicopatología de TCA en comparación con las no atletas. MÉTODO: Siguiendo las guías PRISMA, se identificaron 56 estudios que informaron psicopatología de TCA para atletas femeninas y no atletas. Se completó un modelo de efectos aleatorios de tres niveles de varianza entre y dentro del estudio para las siguientes variables de resultado: psicopatología general de TCA, insatisfacción corporal, impulso por la delgadez, restricción y pérdida de control de la alimentación. RESULTADOS: Las atletas reportaron niveles más bajos de insatisfacción corporal en comparación con las no atletas (g = -.21, p <.0001). Las atletas y las no atletas reportaron niveles similares de psicopatología general de TCA, impulso por la delgadez, restricción y pérdida de control de la alimentación en promedio. El tipo de deporte moderó significativamente los tamaños del efecto de la diferencia de medias estandarizada de la psicopatología de TCA en atletas versus no atletas. Los tamaños del efecto que compararon los niveles de impulso por la delgadez, la restricción y la pérdida de control de la alimentación en atletas versus no atletas fueron mayores para los estudios con atletas que participaron en deportes que valoran lo estético/cuerpo magro, esbelto, en comparación con deportes que no valoran lo estético/cuerpo magro, esbelto. DISCUSIÓN: Los hallazgos de este metanálisis podrían informar la prevención y el tratamiento futuros de los TCA en atletas femeninas al proporcionar más evidencia de que las atletas en deportes que dan un gran valor a lo estético o al cuerpo magro, esbelto, pueden reportar niveles más altos de psicopatología de TCA. Participar en deportes que no dan valor a lo estético o al cuerpo magro, puede ser un factor protector para experimentar menos insatisfacción corporal.

PURPOSE: Emotion regulation (ER) refers to the processes by which individuals influence the onset, intensity, and duration of emotions. Previous studies have examined the effects of adaptive ER and maladaptive ER in isolation, but growing evidence suggests that they should be studied in conjunction. This study examined the interactions between habitual adaptive and maladaptive ER strategies with eating disorder (ED) symptoms and ED-related clinical impairment. METHODS: Students (N = 1377) from a Midwestern American university reported ED symptoms, ED-related impairment, habitual adaptive ER (i.e., cognitive reappraisal), and habitual maladaptive ER (i.e., distraction and suppression). Multiple linear regressions were conducted using the PROCESS v3 macro. RESULTS: The study found that adaptive ER was negatively associated with ED symptoms and ED-related impairment, whereas maladaptive ER was positively associated with both outcome variables. Adaptive ER moderated the association between maladaptive ER and ED symptoms, but not clinical impairment. When habitual adaptive ER was low (< 33.4th percentile), there was no association between maladaptive ER and ED symptoms; however, when habitual adaptive ER was moderate to high (> 33.4th percentile), there was a positive association between frequency of maladaptive ER use and ED symptoms. There was no significant three-way interaction among adaptive ER, maladaptive ER, and probable ED diagnosis, for ED-related impairment or symptoms. CONCLUSION: Results suggest that irrespective of frequency of maladaptive ER, people with low adaptive ER reported elevated psychopathology. Findings point to the utility of interventions to reduce maladaptive ER and increase adaptive ER in ED populations. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Eating disorders (EDs) are serious psychiatric disorders that affect 13%-18% of young men and women. EDs are associated with substantial psychiatric and medical morbidity and mortality, indicating a critical need for improved identification and treatment. Despite the relatively high prevalence and severity of EDs, they are often omitted from discussions of mental health. This comment is in response to Gruber et al. (2020), who wrote an important article on the challenges and opportunities facing clinical scientists in the time of COVID-19. Our response extends Gruber et al.'s article by noting additional challenges facing people with an ED during COVID-19 and recognizing opportunities for improved evidence-based assessment and treatment of this important population.

OBJECTIVE: The study aim was to elucidate the degree to which hyper-palatable foods (HPF) are consumed during binge episodes compared to restricting episodes, and to test the association between HPF intake during each episode and respective episode frequency. METHOD: This study was a secondary analysis of data from a larger study on eating disorders. The present sample included adults (N = 147, 83% women) diagnosed with sub-threshold (41%) or full-threshold (59%) bulimia nervosa (BN). Foods consumed during binge and restricting episodes were assessed using the Eating Pathology Symptoms Inventory-Clinician Rated Version. A standardized definition of HPF developed previously was applied to foods consumed during binge and restricting episodes. A Wilcoxon matched-pairs signed-rank test was used to test the difference between total caloric intake from HPF (KcalHPF) and percentage of caloric intake from HPF (PercHPF) during binge episodes relative to restricting episodes. Four linear regression models tested HPF intake (KcalHPF and PercHPF) during both episode types (binge and restricting) as predictors of respective episode frequency. RESULTS: There was a significant difference between median KcalHPF (1846.6 vs. 279.6; Z = -13.38, p < .001) and PercHPF during binge compared to restricting episodes (95% vs. 61%; Z = -7.35, p < .001). Regression analyses demonstrated that KcalHPF during binge episodes was significantly associated with binge episode frequency (B = 0.002; p < .001), but not PercHPF (p = .287). DISCUSSION: Results suggest that HPF may be primarily consumed during binge episodes among individuals with BN, and may be associated with greater binge-eating frequency. PUBLIC SIGNIFICANCE: Findings from the current study support an underlying assumption of theoretical models of binge eating, suggesting that highly rewarding, hyper-palatable foods (HPF), may constitute the vast majority of energy intake during binge-eating episodes. Additionally, a substantial amount of energy intake from HPF may occur during restricting episodes among people with bulimia nervosa. Greater HPF intake during binge eating may also be associated with binge-eating severity.
