Clinical, Psychological and Personality Features Related to Age of Onset of Anorexia Nervosa

Abstract

To investigate the relationship between age of onset and clinical and personality features of patients with anorexia nervosa (AN). We assessed 250 outpatients with AN with the Temperament and Character Inventory, the Eating Disorder Inventory 2, the Beck Depression Inventory and the Body Shape Questionnaire. The patients were subdivided into 3 groups: early (n=73), intermediate (n=96) and late onset (n=81), based on age of onset of symptoms. The early-onset group shows higher body dissatisfaction, maturity fear, impulsivity and asceticism than the other 2 groups. This group shows a greater character fragility, as described in particular by a lower self-directedness, than the other 2 groups. Even several years after the onset of the disorder, early-onset subjects affected by AN seem characterized by a more disturbed personality, with a higher body dissatisfaction than late-onset subjects affected by AN and a pursuit of thinness based on an ascetic drive.
