ABSTRACT
BACKGROUND:
Patients with anorexia nervosa (AN) show overgeneralization of memory (OGM) when generating autobiographical episodes related to food and body shape. These memories are central for the construction of a coherent self-concept, interpersonal relationships, and problem-solving abilities. The current study aims to investigate changes in autobiographical memory following weight gain.METHODS:
OGM was assessed with an adapted version of the Autobiographical Memory Test including food-, body-, depression-related, and neutral cues. N = 41 female patients with AN (28 restricting-, 13 binge-eating/purging-subtype; mean disease duration 4.5 years; mean BMI 14.5 kg/m2) and N = 27 healthy controls (HC) were included at baseline. After inpatient treatment (mean duration 11 weeks), 24 patients with AN and 24 age-matched HC were reassessed. Group differences were assessed using independent samples t-tests for cross-sectional comparisons and repeated measures ANOVAs for longitudinal data.RESULTS:
At baseline, patients with AN generated significantly fewer specific memories than HC, independent of word category (F(1.66) = 27.167, p < 0.001). During inpatient stay, the average weight gain of patients with AN was 3.1 body mass index points. At follow-up, patients with AN showed a significant improvement in the number of specific memories for both depression-related and neutral cues, but not for food- and body-related cues.CONCLUSIONS:
Generalised OGM (i.e., independent of word category) in patients with AN before weight restoration may be a general incapacity to recall autobiographical memory. After weight gain, the previously well-studied pattern of eating disorder-related OGM emerges. The clinical relevance of the continuing disorder-related OGM in patients with AN after weight gain is discussed.Palavras-chave
