N2 - Objective: To explore the psychometric properties of the Cross-Cultural Questionnaire (CCQ), a new self-report tool for assessing factors of risk and maintenance for eating disorders (ED). Method: Data was collected during a multi-centre case-control study. The sample included 854 ED patients and 784 healthy participants from the UK, Spain, Austria, Slovenia and Italy. Exploratory factor analyses examined the factor structure of each section of the CCQ, and Cronbach's alpha coefficients valued the internal consistency of each derived scale score. Logistic regression and receiver operating characteristic (ROC) curve procedure assessed the screening accuracy and predictive validity of the empirical factors. Results: Based on a total of 127 items, nine dimensions emerged, with satisfactory internal consistency and high congruence between countries. CCQ scores demonstrated satisfactory accuracy for discriminating between ED cases and controls (area under the ROC curve = 0.88). Most of the items achieved discriminative accuracy. Conclusions: This study offers preliminary evidence that the CCQ, available in five languages, is a useful and valid tool to assess factors of risk and maintenance for EDs.
