Background Traditional approaches for the classification of eating disorders (EDs) attribute symptoms to an underlying, latent disease entity. The network approach is an alternative model in which mental disorders are represented as networks of interacting, self-reinforcing symptoms. This project was the first to use network analysis to identify interconnected systems of ED symptoms. Method Adult participants (n = 143; 77.6% women) with a Diagnostic and Statistical Manual of Mental Disorders… 

A network investigation of core symptoms and pathways across duration of illness using a comprehensive cognitive–behavioral model of eating-disorder symptoms

The results suggest that eating when not hungry and feeling fat were the most central symptoms across groups, and the importance of using comprehensive, theoretically- or empirically-derived models for NA is highlighted.

Using network analysis to identify central eating disorder symptoms among men.

The centricity of body dissatisfaction items in the networks supports some components of cognitive behavioral theories of EDs, however, the findings also suggest the importance of muscularity- and leanness-oriented concerns, which have been traditionally neglected from leading ED theories.

Network analysis: An innovative framework for understanding eating disorder psychopathology

An overview of network theory is presented, the existing findings in the ED literature are reviewed, and several areas to address in future ED network analytic research are outlined, which include the use of prospective designs and adoption of multimodal assessment methods.

Core psychopathology of treatment-seeking patients with binge-eating disorder: a network analysis investigation

The results provide support for including shape/weight overvaluation as a diagnostic specifier for binge-eating disorder (BED), the most prevalent eating disorder in the United States.

Transdiagnostic vulnerability factors in eating disorders: A network analysis.

The results suggest that excessive control of bodily aspects by dietary restraint, excessive focus on inhibiting emotions and feelings, interoceptive awareness and perfectionism may be important constructs that warrant future research in understanding vulnerability in EDs.

Application of network analysis to investigate sex differences in interactive systems of eating-disorder psychopathology.

It is suggested that there are more similarities than differences in networks of EDs in men and women, which has important clinical implications by supporting theoretical underpinnings of cognitive-behavioral models ofEDs in both men andWomen.

Network analysis of specific psychopathology and psychiatric symptoms in patients with eating disorders

Findings suggest that-in addition to ED-core symptoms and BMI-depressive and anxiety symptoms, interpersonal sensitivity and ineffectiveness may be important targets to provide effective treatments across AN, BN, and BED.

The psychometric network structure of mental health in eating disorder patients

Novel associations between well‐being and psychopathology in ED patients are shown and central domains and their underlying symptoms may be especially important to consider in treatment for promoting mental health inED patients.

A systematic review of network analysis studies in eating disorders: Is time to broaden the core psychopathology to non specific symptoms

Ineffectiveness, interoceptive ability and affective problems may be included in the core ED psychopathology, in addition to ED‐specific symptoms, as evidence supporting the predictive role of central network nodes is provided.



Network analysis: an integrative approach to the structure of psychopathology.

An examines methodologies suited to identify such symptom networks and discusses network analysis techniques that may be used to extract clinically and scientifically useful information from such networks (e.g., which symptom is most central in a person's network).

Revealing the dynamic network structure of the Beck Depression Inventory-II

The network approach expands the range of depression research, making it possible to investigate the dynamic architecture of depression and opening up a whole new range of questions and analyses.

Development and validation of the Eating Pathology Symptoms Inventory (EPSI).

Eating Pathology Symptoms Inventory scale scores had excellent internal consistency (median coefficient alphas ranged from .84-.89) and reliability over a 2- to 4-week period (mean retest r = .73).

Empirical classification of eating disorders.

The rationale for the RDoC project, its essential features, and potential methods of transitioning from DSM/ICD categories to dimensionally‐oriented designs in research studies are summarized.

Characteristics and stability of empirically derived anorexia nervosa subtypes: towards the identification of homogeneous low-weight eating disorder phenotypes.

Findings support the presence of 3 low-weight eating disorder phenotypes that are highly stable over short-term follow-up, and highlights the importance of studying mechanisms that differentiate fat-phobic and non-fat-phobia eating disorders.

Gender norms, psychometric properties, and validity for the Eating Pathology Symptoms Inventory.

These data provide the first large-scale normative data for the EPSI in young adults, as well as additional evidence supporting the psychometric properties and construct validity of the EPSP, indicating excellent convergent and discriminant validity in both genders.

Daily patterns of anxiety in anorexia nervosa: associations with eating disorder behaviors in the natural environment.

Daily patterns of anxiety in anorexia nervosa are identified and traits of personality pathology and the presence of a co-occurring mood disorder were found to be associated with the tendency to experience particular daily anxiety trajectories.

Binge eating disorder: reliability and validity of a new diagnostic category.

This study lends some support to the concept of BED but suggests that additional studies of the characteristics of this disorder at different degrees of obesity would be useful.
