Changes in insomnia and binge-eating symptom severity before and after treatment of eating disorders in individuals with non-low-weight binge-spectrum disorders.

Although emerging research suggests insomnia is a significant problem among people with eating disorders, little is known about how insomnia symptoms may serve as risk factors for eating disorder symptoms, treatment outcome, and relapse. University students with non-low-weight eating disorders (N = 89) completed a mobile guided self-help cognitive behavioural intervention for eating disorders. Insomnia and binge-eating symptoms were assessed at pre-treatment and end-of-treatment using the Insomnia Severity Index and Eating Pathology Symptoms Inventory.

Compensatory eating disorder and full threshold DSM eating disorders: A comparison of eating-disorder-related psychiatric impairment and symptomatology.

Introduction: Compensatory eating disorder (CED) is a newly proposed 'other specified feeding and eating disorder' characterized by recurrent non-purging compensatory behaviors (e.g., compulsive exercise and/or food restriction), overvaluation of weight/shape, the absence of objective binge-eating episodes, and the absence of low weight or recent significant weight loss.

"There aren't a lot of things that are made for Latinos": A qualitative investigation of factors that contribute to Latine women's positive and negative body image.

Although there has been an increased focus on ethnic diversity in eating-disorder and body-image research, a gap exists in body image programs specifically designed for Latine women. To create programs that are culturally sensitive and relevant, it is important to first understand factors that contribute to Latine women's conceptualizations of body image. Drawing upon open-ended semi-structured interviews with Latine women (N=19, M=20, SD=1.

State of the Science: The Hierarchical Taxonomy of Psychopathology (HiTOP).

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a dimensional framework for psychopathology advanced by a consortium of nosologists. In the HiTOP system, psychopathology is grouped hierarchically from super-spectra, spectra, and subfactors at the upper levels to homogeneous symptom components and maladaptive traits and their constituent symptoms, and maladaptive behaviors at the lower levels. HiTOP has the potential to improve clinical outcomes by planning treatment based on symptom severity rather than heterogeneous diagnoses, targeting treatment across different levels of the hierarchy, and assessing distress and impairment separately from the observed symptom profile.

Integrating "Lumpers" versus "Splitters" Perspectives: Toward a Hierarchical Dimensional Taxonomy of Eating Disorders from Clinician Ratings.

This study describes a hierarchical dimensional model of eating-disorder (ED) classification based on the Hierarchical Taxonomy of Psychopathology (HiTOP). Participants were community-recruited adults with an ED (=252; 81.9% female).

Negative Affect as a Mediator Between Exposure to Fitspiration and Thinspiration and Disordered Eating Behaviors: An Ecological Momentary Assessment Study.

Objective: Although social media use, such as Instagram, has been associated with ED pathology, mechanisms connecting social media use to disordered eating behaviors (DEBs) remain largely unevaluated. Based on Dual Process, Tripartite, and Affect Regulation models of ED pathology, we proposed a moderated mediation model evaluating impacts of exposure to fitspiration/thinspiration on Instagram.

Method: We evaluated a hypothesized pathway from exposure to fitspiration/thinspiration (i.

Associations Between Weight Discrimination, Eating-Disorder-Related Psychiatric Impairment, and Eating-Disorder Treatment Interest Across the Weight Spectrum.

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.

Using item response theory to identify key symptoms of insomnia in a sample of university students with probable eating disorders.

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.

Examining associations between disordered eating and harmful substance use in a nationally representative sample of US veterans.

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.

Weight bias internalization is positively associated with insomnia symptom severity in young women with disordered eating.

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, M=20.

The impact of trauma-related symptoms and neuroticism on compensatory behaviors in a sample of adults with eating disorders.

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.

The Building Healthy Eating and Self-Esteem Together for University Students Mobile App to Treat Eating Disorders: User-Centered Research Design and Feasibility Study.

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.

Eating disorder psychopathology, psychiatric impairment, and symptom frequency of atypical anorexia nervosa versus anorexia nervosa: A systematic review and meta-analysis.

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.

Prospectively predicting naturalistic exposure to fitspiration and thinspiration in young women with disordered eating by leveraging an ecological momentary assessment design.

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.

A pilot multiple-baseline study of a mobile cognitive behavioral therapy for the treatment of eating disorders in university students.

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.

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

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.

Screening for eating disorders across genders in college students: Initial validation of the brief assessment of stress and eating.

Unlabelled: 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).

Generalized network psychometrics of eating-disorder psychopathology.

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.

The Somatoform Spectrum Within the Hierarchical Taxonomy of Psychopathology System: A Taxometric Test of the Latent Structure.

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.

The impact of discrimination on binge eating in a nationally representative sample of Latine individuals.

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.

Eating-disorder psychopathology in female athletes and non-athletes: A meta-analysis.

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.

Habitual adaptive emotion regulation moderates the association between maladaptive emotion regulation and eating disorder symptoms, but not clinical impairment.

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.

Clinical science can address rising eating disorder psychopathology during the COVID-19 pandemic: Comment on Gruber et al. (2020).

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.
