ABSTRACT
Objective:
To evaluate the validity and reliability of the Chinese version of the Eating Disorder Examination Questionnaire 6.0 (EDE-Q 6.0) in female patients with eating disorders.Methods:
A total of 239 patients with eating disorder and 142 healthy controls who were recruited consented to participate in the study and completed Chinese EDE-Q 6.0.Confirmatory factor analysis was used in patients to compare the original 4-factor model,1-factor model and 3-factor model.The criterion validity was tested with the Eating Disorder Inventory (EDI).Mann-Whitney U analysis was used to compare the differences of EDE-Q 6.0 scores on the two samples to test the empirical validity,and ROC analysis was used to determine the cut-off value.The internal consistency of the scale was tested in two samples.Among all participants,89 patients and 31 healthy controls were retested 1 month later.Results:
The original 4-factor model fit better than the other two.The EDE-Q 6.0 total score and the EDI total score had a high consistency in the total sample,patients and controls,respectively (ICC =0.88,0.87,0.73).Patients had higher scores on the EDE-Q 6.0 than controls (Ps <0.01).The mean area under the curve (AUC) of EDE-Q 6.0 was 0.91,the optimal cut-off point of EDE-Q 6.0 was total score ≥ 1.27,sensitivity and specificity were 79.4% and 88.2% respectively.The Cronbach α coefficients were 0.95,0.91,and 0.88 for the total sample,patients and controls respectively.The test-retest reliabilities were 0.73 for the total scale,0.58,0.68,0.69 and 0.71 for the 4 factors.Conclusion:
The Chinese version of the Eating Disorder Examination Questionnaire 6.0 have good psychometric properties and diagnosis accuracy,and it could be used to assess the severity of clinical symptoms.
