Sleep, anxiety, and worry are strongly related to psychiatric illness and eating disorder symptoms; it is unclear how these specific sleep and anxiety symptoms are interrelated with anorexia nervosa (AN) pathology. Authors investigate this link.
Sleep, anxiety, and worry are strongly related to psychiatric illness and eating disorder symptoms; it is unclear how these specific sleep and anxiety symptoms are interrelated with anorexia nervosa (AN) pathology. Authors used network analysis to explore pathways among sleep disturbance, anxiety, worry, and ED symptoms in 267 participants with a diagnosis of AN or atypical AN. They identified core symptoms and illness pathways supporting the theoretical conceptual model of how ED symptoms, anxiety, worry, and sleep disturbances inter-relate in AN and atypical AN. Researchers also found that symptoms associated with sleep and anxiety had strong connections with AN symptoms. In addition, this data suggest that targeting sleep disturbance, anxiety, and worry could improve treatment for AN.
