Purpose Although the EDE-Q is derived from the “gold standard” for the assessment of Eating Disorders (ED), its factor structure is controversial, particularly in male samples. The aim of the study was to examine the psychometric properties and factor structure of the EDE-Q, as well to stablish a sensitive and specific cut-off point validated by EDE clinical interview.
Methods A series of Confirmatory Factor Analyses were performed among a representative sample of 796 male university students, of whom 139 were interviewed. Sensitivity and specificity were calculated by Receiver Operating Characteristic (ROC) analysis to determinate the most appropriate cut-off value.
Results The original factor structure was not confirmed, showing a better fit with a 2-factor solution. For the Spanish male sample, a cut-off ≥ 1.09 for at-risk of ED cases and ≥ 2.41 for clinical cases presents an optimal balance between sensitivity and specificity.
Conclusions The establishment of specific cut-off points for males may help to reduce the under-diagnosis of ED in this population.
Level of evidence III Evidence obtained from well-designed case-control study.
