The assessment of binge eating disorder in obese women: a comparison of the binge eating scale with the structured clinical interview for the DSM-IV.
The purpose of the present study was to evaluate the clinical usefulness of the Portuguese version of the Binge Eating Scale (BES) to assess binge eating disorder (BED) in a clinical sample. The BES is a self-reported instrument developed to identify binge eaters within the obese population. The scale, at the cutoff point of 17, was compared with the Structured Clinical Interview for the DSM-IV-Patient version (SCID-I/P). It was administered to 178 obese Brazilian women, aged 18 to 60 years, seeking treatment for obesity at an outpatient clinic. To assess the test-retest reliability, 121 individuals filled the instrument again 15 days later. The Portuguese version of BES showed a sensitivity of 97.8%, a specificity of 47.7%, a positive predictive value of 66.7% and a negative predictive value of 95.3%. The test-retest reliability, measured by kappa statistics, was 0.66. Cronbach's alpha was 0.89. These results suggest that the BES is valid as a screening instrument for BED in obese Brazilian women seeking treatment for obesity.
