R. Palmer et al., THE CLINICAL EATING DISORDERS RATING INSTRUMENT (CEDRI) - A VALIDATION-STUDY, European eating disorders review, 4(3), 1996, pp. 149-156
The study was designed to test the validity of the CEDRI, a semi-struc
tured interview for the assessment of much of the psychopathology and
behaviours associated with the clinical eating disorders. Evidence of
its reliability has previously been published. The present study exami
nes the ratings obtained from clinical samples of subjects with anorex
ia nervosa (n=39) and bulimia nervosa (n=97) and compares them with a
comparison group of women (n=98) who were dieting but not eating disor
dered. Statistically significant differences were found between the cl
inical samples and the comparison group on almost all items. The overa
ll pattern of results provides evidence for the validity of the instru
ment.
