The aim of the present study is to assess the psychometric properties of the Eating Disorder Examination (EDE) 12.0D in obese adult patients without Binge Eating Disorder (BED). A consecutive series of 115 obese patients without BED (23 M; 92 F), seeking treatment for obesity at the Outpatient Clinic of the Section of Metabolic Diseases and Diabetology of the University of Florence was studied using the EDE 12.0D. Patients had a mean (+/- SD) age of 40.8 +/- 15.1 years, and a Body Mass Index (BMI) of 36.3 +/- 5.9 Kg/m2. Internal consistency of EDE and its scales was evaluated through Cronbach's alpha; factor structure of EDE 12.0D was studied with factor analysis. EDE total and Shape Concern (SC) scores were found to be higher in females than in males. EDE total, SC and Eating Concern (EC) scores were inversely correlated to age, but not BMI. Factor analysis suggested the grouping of items in two subscales. The first scale includes all the items from EC, Weight Concern (WC) and SC except reaction to prescribed weighing; the second scale consists of all the items from Restraint. Data obtained show that items from EC, WC and SC all converge into the same factor analysis derived scale in obese patients without BED. EDE 12.0D provides relevant information about psychopathological features of obese patients, but a grouping of items into subscales different from those originally described could be indicated.
