dc.description.abstract	Objective: The revised Eating Disorder Core Beliefs Questionnaire (ED-CBQ-R) is a 15-item self-report questionnaire which assesses the endorsement of underlying core beliefs relevant to eating disorders. As this measure has not yet been validated in a secondary sample since its development, the current study aimed to evaluate the factor structure, validity, reliability and discriminative ability of the ED-CBQ-R in a sample of Australian men and women. Method: Undergraduate students (N = 283) completed an online test battery of questionnaires. Confirmatory factor analyses and linear regression analyses were performed, and group differences, internal consistency, and construct validity of the ED-CBQ-R examined. Results: Results of the CFA suggested acceptable to good model fit to the observed data in the current non-clinical sample. The total measure and its four subscales displayed acceptable to good internal consistency and good convergent and divergent validity. Females (n = 148) had significantly higher negative core beliefs across all subscales compared to males (n = 134). A subgroup of participants with self-reported eating disorder symptomatology (n = 62) had higher scores on the total ED-CBQ-R, Self-loathing, Demanding, Unassertive and Abandoned subscales, compared to the subgroup of participants without self-reported eating disorder symptoms (n = 221). Conclusions: Our findings suggest the ED-CBQ-R has strong psychometric properties and the potential to be a theoretically and clinically useful assessment tool in Australian samples. However, the ED-CBQ-R requires further investigation in clinical eating disorder samples before recommendations for its clinical utility can be fully supported.

Abstract:

Objective: The revised Eating Disorder Core Beliefs Questionnaire (ED-CBQ-R) is a 15-item self-report questionnaire which assesses the endorsement of underlying core beliefs relevant to eating disorders. As this measure has not yet been validated in a secondary sample since its development, the current study aimed to evaluate the factor structure, validity, reliability and discriminative ability of the ED-CBQ-R in a sample of Australian men and women. Method: Undergraduate students (N = 283) completed an online test battery of questionnaires. Confirmatory factor analyses and linear regression analyses were performed, and group differences, internal consistency, and construct validity of the ED-CBQ-R examined. Results: Results of the CFA suggested acceptable to good model fit to the observed data in the current non-clinical sample. The total measure and its four subscales displayed acceptable to good internal consistency and good convergent and divergent validity. Females (n = 148) had significantly higher negative core beliefs across all subscales compared to males (n = 134). A subgroup of participants with self-reported eating disorder symptomatology (n = 62) had higher scores on the total ED-CBQ-R, Self-loathing, Demanding, Unassertive and Abandoned subscales, compared to the subgroup of participants without self-reported eating disorder symptoms (n = 221). Conclusions: Our findings suggest the ED-CBQ-R has strong psychometric properties and the potential to be a theoretically and clinically useful assessment tool in Australian samples. However, the ED-CBQ-R requires further investigation in clinical eating disorder samples before recommendations for its clinical utility can be fully supported.
