Abstract

Purpose: To examine the potential factor structure of the Eating Disorder Diagnostic Scale (EDDS) in a sample of individuals with bipolar disorder. Method: Exploratory common factor analyses were conducted in a sample of 1031 people with bipolar disorder as defined by the Structured Clinical Interview for DSM-IV-TR. Results: Approximately 27% of participants had a comorbid eating disorder. Exploratory factor analysis yielded a 3 factor solution (i.e., shape/weight concerns; binge eating behaviors, compensatory behavior). Conclusions: The 3-factor solution of the EDDS in a bipolar disorder sample is consistent with major eating disorder symptom domains. Future research is necessary to replicate these findings in eating disorder samples with diverse comorbid psychopathology.
