Factor analysis of the eating disorder diagnostic scale in individuals with bipolar disorder.Eat Behav. 2019 04; 33:30-33.EB
To examine the potential factor structure of the Eating Disorder Diagnostic Scale (EDDS) in a sample of individuals with bipolar disorder.
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.
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).
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.
