Core psychopathology in anorexia nervosa and bulimia nervosa: A network analysis
About this resource
Objective The cognitive?behavioral theory of eating disorders (EDs) proposes that shape and weight overvaluation are the core ED psychopathology. Core symptoms can be statistically identified using network analysis. Existing ED network studies support that shape and weight overvaluation are the core ED psychopathology, yet no studies have estimated AN core psychopathology and concerns exist about the replicability of network analysis findings. The current study estimated ED symptom networks among people with anorexia nervosa (AN) and bulimia nervosa (BN) and among a combined group of people with AN and BN. Method Participants were girls and women with AN (n = 604) and BN (n = 477) seeking residential ED treatment. ED symptoms were assessed with the Eating Disorder Examination?Questionnaire (EDE?Q); 27 of the EDE?Q items were included as nodes in symptom networks. Core symptoms were determined by expected influence and strength values. Results In all networks, desiring weight loss, restraint, shape and weight preoccupation, and shape overvaluation emerged as the most important symptoms. In addition, in the AN and combined networks, fearing weight gain emerged as an important symptom. In the BN network, weight overvaluation emerged as another important symptom. Discussion Findings support the cognitive?behavioral premise that shape and weight overvaluation are at the core of AN psychopathology. Our BN and combined network findings provide a high degree of replication of previous findings. Clinically, findings highlight the importance of considering shape and weight overvaluation as a severity specifier and primary treatment target for people with EDs.
A systematic review of the literature on family functioning across all eating disorder diagnoses in comparison to control families
The objectives of this review were to systematically identify and evaluate quantitative research comparing family functioning (a) in eating disorder families with control families, (b) in families with different eating disorder diagnoses (c) perceptions of different family members and (d) the relationship between family functioning and recovery.Read more
Treatment of anorexia nervosa in a specialty care continuum
OBJECTIVE: Inpatient hospitalization has been a mainstay of treatment for anorexia nervosa (AN), but decreasing lengths of inpatient stay have prompted the development of alternative care-continuum models.Read more

Restrictive eating behaviors are a nonweight-based marker of severity in anorexia nervosa
OBJECTIVE: The purpose of this study was to compare the type and frequency of restrictive eating behaviors across the two subtypes of anorexia nervosa (AN; restricting [ANr] and binge eating/purging [ANbp]) using ecological momentary assessment (EMA) and to determine whether subtype differences in restrictive eating behaviors were attributable to severity of the disorder or the frequency of binge eating.Read more
