Factor structure end psychometric properties of the brief mizes anorectic cognitions questionnaire

The Mites Anorectic Cognitions-Revised (MAC-R) questionnaire is a 24-item s ell-report instrument designed to assess cognitions associated with anorexi a and bulimia nervosa, We examined the factor structure and psychometric pr operties of the MAC-R in a sample of 290 undergraduates. We found that a br ief 3-factor oblique model (composed of 12 items) of the MAC-R provided acc eptable fit to the present sample data. This model was largely invariant ac ross male and female participants. The brief version oi the MAC-R (the BMAC ) and subscale scores correlated significantly with scores from related mea sures of eating disorders, showing evidence of concurrent validity. The BMA C total and subscales also showed evidence of discriminant validity by diff erentiating between empirically defined subclinical eating disorders and co ntrol participants. Both logistic regression and discriminant function anal yses showed that only the self-control and self-esteem subscale was most us eful in distinguishing between the subgroups.
