A course of treatment of binge eating disorder: a time series approach

Objective The aim of the study was an analysis of the therapeutic course of treatment of a patient with binge eating disorder (BED), who participated in the multi-modal intervention programme at the Medical University Hospital of Heidelberg. Method Throughout the course of the treatment period, the patient answered questions daily on a handheld computer about her eating behaviour as well as her psychological and physical state. Diary data was analysed with a time series analysis method. Results Multiple regression analysis revealed that both depression and distress were same-day predictors for eating behaviour. Delayed predictors were both the eating behaviour and the anxiety of the previous day, as well as the activity 2 days earlier. The model accounts for 55% of the total variance. Discussion The findings of this study expand upon the evidence of previous cross-sectional studies, suggesting that the development process of the eating behaviour during treatment is strongly associated with affective variables. The study demonstrates that changes that occur during the treatment occur simultaneously on multiple levels. The causal interpretation of the delayed predictors shows that for this patient anxiety is a trigger of binge eating episodes. Copyright © 2006 John Wiley & Sons, Ltd and Eating Disorders Association.
