Factors of risk and maintenance for eating disorders: Psychometric exploration of the cross-cultural questionnaire (CCQ) across five European countries

Abstract

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.

Logistic regression and receiver operating characteristic (ROC) curve procedure assessed the screening accuracy and predictive validity of the empi..
