Abstract
PURPOSE: The aim of this study was to develop an Arabic version of the EDE-Q and to assess its psychometric properties and utility as a screener in the Saudi population. An additional aim was to establish EDE-Q norms for Saudis. METHOD: EDE-Q data were collected in a convenience sample of the Saudi community (N = 2690), of which a subset was also subjected to the EDE interview (N = 98). Various models for the factor structure were evaluated on their fit by CFA. With ROC analysis, the AUC was calculated to test how well the EDE-Q discriminated between Saudis at high and low risk for eating disorders. RESULTS: The original four factor model of the EDE-Q was not supported. Best fit was found for a three factor model, including the weight/shape concern scale, dietary restraint scale and eating concern scale. The ROC analysis showed that the EDE-Q could accurately discriminate between individuals at high and low risk for an eating disorder according to the EDE interview. Optimal cut off of 2.93 on the global score yielded a sensitivity of 82% and specificity of 80%. EDE-Q scores were fairly associated with BMI. DISCUSSION: Psychometric characteristics of the Saudi version of the EDE-Q were satisfactory and results support the discriminant and convergent validity. Severity level of eating disorder pathology can be determined by the EDE-Q global score. Global scores were high compared to what is found in Western community samples, leading to high prevalence estimates for Saudis at high risk for eating disorders. LEVEL OF EVIDENCE: Not applicable, empirical psychometric study.
