Mood changes in bulimia nervosa
EC Johnson-Sabine, KH Wood and A Wakeling
Daily measurement of mood, and the occurrence of specific eating
behaviours, were assessed concurrently over an eight-week period in a
sample of 50 patients meeting diagnostic criteria for bulimia nervosa.
Results of observer-rated scales of mood showed a significant reduction of
scores, whereas self-assessment of mood showed no change over the study
period. Negative mood states, although not severe, were more marked when
the specific behavioural symptoms of binge-eating, vomiting, or purging
occurred, and they increased as abnormal eating behaviours accumulated. It
is suggested that the accompanying dysphoric mood states of bulimia nervosa
are likely to be a secondary manifestation related to the presence of
abnormal eating symptoms, and that they do no constitute a primary
depressive illness.
