Differentiating anorexia nervosa and atypical anorexia nervosa with absolute weight cut-offs results in a skewed distribution for premorbid weight among youth Int. J. Eat. Disorder. (IF 5.5) Pub Date : 2024-03-08 Abigail Matthews, Jessica Lin, Grace Jhe, Triinu Peters, Leslie Sim, Johannes Hebebrand
Anorexia nervosa (AN) and atypical AN are conceptualized as distinct illnesses, despite similar characteristics and sequelae. Whereas DSM-5 differentiates youth with AN and atypical AN by the presence of clinical ‘underweight’ (i.e., 5th BMI percentile for age-and-sex (BMI%)), we hypothesized that using this weight cut-off to discern diagnoses creates a skewed distribution for premorbid weight.

A new conceptual model for anorexia nervosa: A role for connective tissue? Int. J. Eat. Disorder. (IF 5.5) Pub Date : 2024-02-19 Dennis Gibson, Philip S. Mehler
The etiology of anorexia nervosa (AN) remains to be fully elucidated, and current theories also fail to account for the direct effect of starvation on the health of the organs and tissues, specifically the connective tissue present in most organs of the body. Individuals with hereditary disorders of connective tissue manifest with clinical symptoms that overlap with AN, as the abnormal connective tissue

A meta-analysis of disordered eating and its association with self-criticism and self-compassion Int. J. Eat. Disorder. (IF 5.5) Pub Date : 2024-02-17 Sarah Marie Paranjothy, Tracey D. Wade
Future treatments for eating disorders (ED) need to be enhanced by targeting maintaining mechanisms. Literature suggests self-criticism and self-critical perfectionism act as key mechanisms exacerbating ED, and self-compassion protects against self-criticism. This meta-analysis examines associations between self-criticism and self-critical perfectionism on disordered eating (DE), and reviews how self-compassion

Expectations of a new eating disorder treatment and its delivery: Perspectives of patients and new therapists Int. J. Eat. Disorder. (IF 5.5) Pub Date : 2024-02-15 Therese Fostervold Mathisen, Gunn Pettersen, Jan H. Rosenvinge, Ulrike H. Schmidt, Jorunn Sundgot-Borgen
A significant number of people with bulimia nervosa (BN) or binge-eating disorder (BED) do not seek professional help. Important reasons include limited knowledge of eating disorders (EDs), feelings of shame, treatment costs, and restricted access to specialized healthcare. In this study, we explored if a novel therapy delivered in a primary care setting could overcome these barriers. We investigated

Envisioning an improved research strategy for detecting moderators/mediators in intervention studies: A commentary on McClure et al. Int. J. Eat. Disorder. (IF 5.5) Pub Date : 2024-02-14 Helena Chmura Kraemer
The goal of moderator/mediator research in treatment evaluation is to provide guidance to clinicians to choose the best treatment for each patient with a disorder (moderators), and to advise on its optimal protocol or implementation (mediators): personalized/precision medicine. McClure et al. report a systematic review of studies addressing moderators/mediators of the treatment effect of digital interventions
