Autobiographical memory deficit in anorexia nervosa: emotion regulation and effect of duration of illness.
Emotional deficits in anorexia nervosa can be expressed in autobiographical memory recall. The aim of this study is to test whether deficits in autobiographical memory exist in anorexic patients and concern specifically negative or positive emotional valence. Moreover, it is unclear whether these deficits are dependent upon comorbid aspects (depression, alexithymia, and anxiety) or upon illness duration. Anorexic patients (n=25) were compared to healthy volunteers based on their clinical assessment, explicit memory test score, and autobiographical memory test score. The study makes use of the autobiographical test of Williams and Scott, which involves specific emotional cues to elicit memory. Anorexic patients recalled more general memories than controls in autobiographical memory test, but had no deficit in explicit memory test. This pattern, observed both for negative and positive cues, was neither related to depression or alexithymia, nor to anxiety severity, but increased significantly with illness duration. These results show that anorexic patients are characterized by relative difficulty in the integration of both negative and positive emotional experiences, and that this impairment is reinforced by illness duration.
