The CORE-OM showed good acceptability, acceptable internal and test-retest reliabilities, as well as good convergent and known groups validity, and is supported as a reliable and valid measure for assessing psychological distress in eating disorders. AbstractAim: The current study aimed to explore the psychometric properties of the CORE-OM (Clinical Outcomes in Routine Evaluation – Outcome Measure) when used in an eating disorder sample. Method: The CORE-OM was administered at assessment to 360 individuals referred to an eating disorders service. Principal component analysis was conducted to look at the psychometric structure of the CORE-OM, and psychometric properties were investigated using analyses of reliability and validity. Results: Analyses of the psychometric structure suggested a three-component solution reflecting negatively worded, positively worded and risk items. The CORE-OM showed good acceptability, acceptable internal and test-retest reliabilities, as well as good convergent and known groups validity. Conclusions: The results of the current study support the CORE-OM as a reliable and valid measure for assessing psychological distress in eating disorders.
