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., (© 2024 Wiley Periodicals LLC.)

Objective: Sleep disturbance is common among individuals with eating disorders (EDs), with approximately 50% of patients with EDs reporting sleep disturbance. Sleep problems may promote, exacerbate, or maintain ED symptoms through a variety of hypothesized mechanisms, such as impaired executive function, increased negative affect, and disruptions to appetitive rhythms. Although research investigating the role of sleep in EDs is growing, the current literature suffers from methodological limitations and inconsistencies, which reduce our ability to translate findings to improve clinical practice. The purpose of this forum is to propose a coordinated approach to more seamlessly integrate sleep research into ED research with particular emphasis on best practices in the definition and assessment of sleep characteristics., Methods: In this article, we will describe the current status of sleep-related research and relevant gaps within ED research practices, define key sleep characteristics, and review common assessment strategies for these sleep characteristics. Throughout the forum, we also discuss study design considerations and recommendations for future research aiming to integrate sleep research into ED research., Results/discussion: Given the potential role of sleep in ED maintenance and treatment, it is important to build upon preliminary findings using a rigorous and systematic approach. Moving forward as a field necessitates a common lens through which future research on sleep and EDs may be conducted, communicated, and evaluated., (© 2024 Wiley Periodicals LLC.)

Objectives: Both disordered eating and disturbed sleep represent significant threats to mental health. Accumulating evidence suggests that disordered eating behaviors and sleep problems co-occur. A majority of current research, however, has focused on these behaviors as components of eating disorder diagnoses, rather than investigating the independent associations of transdiagnostic disordered eating behaviors and sleep. The present study sought to examine fasting, binge eating, self-induced vomiting, laxative or diuretic misuse, and driven exercise as predictors of sleep quality complaints., Method: An online sample of 648 U.S. adults completed the Eating Disorder Examination - Questionnaire, the Pittsburgh Sleep Quality Index, and the Patient Health Care Questionnaire-2 as part of a larger parent study., Results: Results of a hierarchical linear regression revealed that, collectively, disordered eating behaviors predicted worse sleep quality [R 2  = 0.30, F(7, 640) = 31.21, p < .001], and that both binge eating and fasting, but not other compensatory behaviors, accounted for unique variance in sleep quality after controlling for BMI and depression., Conclusions: Overall, findings suggest that transdiagnostic disordered eating behaviors are associated with sleep quality complaints. Improved understanding of the specific relationships between individual eating behaviors and sleep characteristics can help refine the identification of individuals at high risk for sleep disturbance and address the potential reciprocal influence of sleep quality on disordered eating behaviors., (© 2024.

This study evaluated symptoms assessed in common measures of eating disorder pathology and tested overlap to evaluate the extent to which measures may be interchangeable. Six measures were included: Bulimia Test-Revised, Eating Attitudes Test-26, Eating Disorder Diagnostic Scale, Eating Disorder Examination Questionnaire, Eating Pathology Symptoms Inventory, and Questionnaire for Eating Disorder Diagnoses. Content overlap was quantitatively estimated using the Jaccard Index. Mean overlap was low (.195), likely due to the wide range of symptoms (87) assessed. The mean overlap of each measure with all others was .117 - .267, and the overlap among individual measures was .083 - .382. Implications of low overlap among measures include variable characterization of eating disorder phenotypes and the risk for lower generalizability of findings due to measurement variability., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

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 age =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., Competing Interests: Declaration of conflicts of interest The authors report there are no competing interests to declare., (Copyright © 2023 National Sleep Foundation.

Background: Despite a growing literature characterizing risk factors associated with the development and maintenance of borderline personality disorder (BPD), substantially less is known about potentially protective factors in BPD., Methods: In a sample of online (N = 272) participants with likely BPD, major depressive disorder (MDD), or no disorder (ND) and an independent sample of in-person (N = 90) participants diagnosed with BPD, MDD, or ND, we tested the cross-sectional and longitudinal associations among BPD features and three putatively protective personality, cognitive, and affective-behavioral factors: conscientiousness, self-compassion, and distress tolerance., Results: Only conscientiousness was significantly lower in BPD than MDD (ds: .67-.73) across both studies and more strongly related to BPD features (rs: -.68 to -.59) than MDD symptoms (rs: -.49 to -.43) in dimensional analyses across both studies. However, in a multiple regression analysis including all three factors in Study 1, only self-compassion predicted decreases in BPD features (β = -.28) and MDD symptoms (β = -.21) over one month., Limitations: Study 1 participants completed all measures online and exhibited some differential attrition at one month follow-up. Study 2 participants were all diagnosed by one trained assessor and the smaller sample size limited our power to detect effects., Conclusions: Low conscientiousness may be most strongly related to BPD, whereas self-compassion may be a prospective transdiagnostic protective factor., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2023 Elsevier B.V.

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, M age  = 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., Competing Interests: Declaration of competing interest The authors report no competing interests., (Copyright © 2023 Elsevier Ltd.

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., (©Kelsie T Forbush, Kara A Christensen Pacella, Marianna L Thomeczek, Sara R Gould, Danielle A N Chapa, Brianne N Richson, Victoria L Perko, Joseph Ayres, Yiyang Chen, Sonakshi Negi.
