Establishing the optimal male cut-off point: confirmatory factor analysis of the eating disorder examination-questionnaire (EDE-Q) in a representative sample of Spanish university students.

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 as to establish a sensitive and specific cut-off point validated by EDE clinical interview.
