OBJECTIVE: The prognosis in cases of anorexia nervosa (AN) is unsatisfactory, and it is therefore important to examine pretreatment predictors of outcome.METHODS: Female AN patients (N = 74) included in a randomised controlled trial receiving individual cognitive behavioural therapy (CBT) or family-based treatment (FBT) were included. Predictors of the outcome were explored using pretreatment eating disorder psychopathology.RESULTS: In the CBT group, lower levels of emotional dysregulation and greater deficits in identifying and coping with inner states were predictors of weight increase, explaining 37.7% of the variance. In the FBT group, lower interoceptive deficits predicted an increase in weight (explaining 17.7% of the variance), whereas bulimic behaviour (32.4%) and problems with emotional regulation (23.3%) were predictors of increased diagnostic symptoms.CONCLUSIONS: Bulimic symptoms and the ability to identify and cope with emotional states appear to be important aspects that should be addressed in the treatment of young adult patients with AN.
