N2 - OBJECTIVE: Research evidence suggests the need to identify treatments based on a more precise characterization of psychopathology and psychiatric comorbidity in anorexia nervosa. Network analysis provides a new method to conceptualize psychopathology. We use this approach to investigate the relationships between eating disorder and general psychiatric symptoms in adolescents with anorexia nervosa.METHODS: Four-hundred and five adolescents with anorexia nervosa and illness duration less than 3 years were consecutively recruited from those admitted to inpatient treatment. They completed the following questionnaires: the Eating Disorder Inventory-3, the Multidimensional Anxiety Scale for Children, the Children's Depression Inventory, and the Youth Self Report. A network analysis was conducted, including eating psychopathology measures, anxiety and depressive symptoms, and obsessive-compulsive and post-traumatic stress problems. We employ a novel approach, the bridge function, to identify symptom clusters.RESULTS: Depression symptoms and personal alienation were the nodes with the highest centrality in the network, followed by asceticism, post-traumatic stress problems, drive to thinness, low self-esteem, and anxiety physical symptoms. Three symptom clusters (relative to eating disorder psychopathology, self-esteem problems, and internalizing difficulties) were identified. Depression symptoms, personal alienation, low self-esteem, and interoceptive deficits showed the highest bridge centrality. Besides eating disorder core symptoms, negative affect and internalizing symptoms seem to contribute to anorexia nervosa psychopathology independently from illness duration effects.DISCUSSION: These findings suggest that anorexia nervosa is characterized by a broad psychopathological spectrum rather than the mere eating disorder core symptoms, confirm the need to re-conceptualize psychiatric comorbidity in this disorder, and provide intriguing diagnostic and therapeutic implications.
