Anxiety in the eating disorders: understanding the overlap.
This paper reviews research investigating the comorbidity between eating disorders and anxiety disorders. Whilst there is some inconsistency in the literature, it appears that women with eating disorders have higher rates of anxiety disorders than normal controls. Potential causal relationships between eating disorders and anxiety disorders are outlined, though their relative chronology appears to be somewhat inconsistent. Safety behaviours and cognitive avoidance strategies (i.e., cognitive narrowing and blocking) are suggested as potential mechanisms linking the disorders. A model outlining this hypothesised relationship is developed throughout the review. It is suggested that eating disorders and anxiety disorders might share common aetiological factors, and that these factors can increase an individual's susceptibility to either disorder. Potential implications for the treatment of eating disorders are outlined, and suggestions are made for further research.
