Assessment of eating disorders: comparison of interview and questionnaire data from a long-term follow-up study of bulimia nervosa.
OBJECTIVE This paper examines diagnostic agreement between interview and question naire assessment s of women participating in a long-term follow-up study of bulimia nervosa . METHODS Women ( N = 162 ) completed follow-up evaluations  comprising question naires and either face-to-face or telephone interviews . RESULTS Consistent with previous research , rates of eating disorders were higher when assessed by question naire than when assessed by interview ; however , rates of full bulimia nervosa were similar . Overall diagnostic agreement was adequate for eating disorders ( kappa=.64 ) but poor for bulimia nervosa ( kappa=.49 ) , with greater agreement between question naires and telephone interviews ( kappa 's range : .67-.71 ) than between question naires and face-to-face interviews ( kappa 's range : .35-.58 ) . CONCLUSION Findings support the possibility that increased rates of eating pathology on question naire assessment s may be due , in part , to increased c and or when participants feel more anonymous . Question naire assessment s may not be inferior to interview assessment s ; they may reveal different aspects of disordered eating
