Abstract
Objective: At present there is no clear, cohesive, and comprehensive theoretical understanding of the role of core beliefs in the development of disordered eating. The present study aimed to develop and test a theoretical model outlining important processes and pathways from core beliefs to eating disorder (ED) behaviours. It also aimed to explore potential differences (or similarities) in contributions of four core belief dimensions to the development and maintenance of ED symptomatology.
Method: Data were collected from a sample of 800 non-clinical participants. Path analysis was conducted to test general and multi-dimensional models. Indirect effects were calculated for all possible pathways from ED core beliefs to dietary restraint, objective binge eating, and compensatory behaviours.
Results: The hypothesised model demonstrated poor to acceptable fit to the data. Modifications were made to the general model to improve fit, remove non-significant paths and add theoretically and statistically relevant paths. All indirect effects of possible pathways from core beliefs to ED behaviours were significant. A multi-dimensional version of the model was tested with four core belief dimensions. This model identified differences in pathways from each core belief dimension to ED symptoms.
Discussion: This study extends the current understanding of the role of core beliefs in the development and maintenance of disordered eating, by building upon previous theoretical models and empirical literature. We present a general core beliefs model of disordered eating, and preliminary findings regarding differences in the processes and pathways from four key core belief dimensions to ED behaviours.
期刊介绍:
Journal of Eating Disorders is the first open access, peer-reviewed journal publishing leading research in the science and clinical practice of eating disorders. It disseminates research that provides answers to the important issues and key challenges in the field of eating disorders and to facilitate translation of evidence into practice.
The journal publishes research on all aspects of eating disorders namely their epidemiology, nature, determinants, neurobiology, prevention, treatment and outcomes. The scope includes, but is not limited to anorexia nervosa, bulimia nervosa, binge eating disorder and other eating disorders. Related areas such as important co-morbidities, obesity, body image, appetite, food and eating are also included. Articles about research methodology and assessment are welcomed where they advance the field of eating disorders.
