“…The sample size also restricted our ability to compare networks based on treatment characteristics, such as comparing networks of those who responded versus did not respond to treatment or comparing networks based on the different treatments involved in the study. Results may not generalize to demographic groups not well represented in the study [e.g., men, people of color (Perez et al, 2021)]. Moreover, results may not generalize to individual people, who demonstrate variable eating disorder symptom centrality at baseline (Levinson et al, 2022).…”

Objective: Effective treatments exist for binge-eating disorder (BED), although roughly 50% of patients fail to attain binge-eating abstinence. Evidence on how to refine treatments is lacking. Conceptualizing BED as arising from a network of symptom-to-symptom interactions allows for the identification of the most strongly connected symptoms, which could inform intervention targets. This study assessed how BED symptom centrality changed with behaviorally based weight-loss treatments (BBWLTs). Methods: Participants were 191 adult patients (71% female, 79% White) with BED with comorbid obesity participating in a randomized controlled trial testing 6-month BBWLTs for BED. Independent assessments of BED symptoms were performed at pretreatment, posttreatment, and 12 months after treatment. Strength centrality indicated how strongly and frequently symptoms were associated with each other in the network. Significant changes in centrality between timepoints were determined using permutation tests. Results: At pretreatment, overvaluation of shape/weight and preoccupation with shape/weight and food/eating had the highest strength centrality. At posttreatment and 12-month follow-up, dissatisfaction with shape/weight had the highest centrality, which significantly increased from pretreatment. Conclusions: The relations among symptoms of BED are not static and change over time with treatment. BBWLTs do not appear to reduce connectivity of overvaluation of shape/weight (the most central BED symptom prior to treatment), but instead increase connectivity of dissatisfaction with shape/weight with other symptoms following treatment. The observed network structure of symptoms following BBWLTs resembles network analyses of people without eating disorders. Findings highlight the importance of understanding how treatments impact symptom relationships, not just symptom intensities.

Network science represents a powerful and increasingly promising method for studying complex real-world problems. In the last decade, it has been applied to psychometric data in the attempt to explain psychopathologies as complex systems of causally interconnected symptoms. With this work, we aimed to review a large sample of network-based studies that exploit psychometric data related to eating disorders (EDs) trying to highlight important aspects such as core symptoms, influences of external factors, comorbidities, and changes in network structure and connectivity across both time and subpopulations. A particular focus is here given to the potentialities and limitations of the available methodologies used in the field. At the same time, we also give a review of the statistical software packages currently used to carry out each phase of the network estimation and analysis workflow. Although many theoretical results, especially those concerning the ED core symptoms, have already been confirmed by multiple studies, their supporting function in clinical treatment still needs to be thoroughly assessed.

“…Latinx adults tend to report higher weight and shape concerns than non-Latinx adults [15], with weight concerns (i.e. strong desire to lose weight and fear of weight gain) constituting a central symptom of eating disorder among ethnic minority women [16]. Rates of compensatory behaviours such as excessive exercising, self-induced vomiting and laxative misuse have been comparable among Hispanic and White women [17].…”

Purpose of reviewThis review provides a 6-year update on the prevalence and treatment of eating disorders among Hispanic/Latinx Americans in the United States.Recent findingsPrevalence of eating disorders tends to be lower in Hispanic/Latinx American adolescents and adults relative to non-Hispanic White peers. Numerous risk factors for disordered eating symptoms have been identified, including negative body image, depression, sexual assault and culturally specific risk factors, including ethnic discrimination and acculturative stress. Hispanic/Latinx individuals seek treatment less often with the most influential barriers being cost of treatment, eating disorder stigma, eating disorder shame and mental health shame in general. Limited research on the treatment for eating disorders continue to persist. Culturally adapted cognitive behavioural therapy yielded similar outcomes to traditional cognitive behaviour therapy and had better treatment adherence and retention rates.SummaryThe medical and sociopolitical climate of the United States has changed significantly since our previous review. The need for research on the effectiveness of eating disorder treatments for Hispanic/Latinx Americans remains important for one of the fastest growing populations in the U.S.
