Continuity and discontinuity models of bulimia nervosa: A taxometric investigation

Past research evaluating the: continuity and discontinuity models of bulimi a has produced inconclusive results. In the current study, we performed a t axometric analysis of bulimia nervosa using means above minus below a slidi ng cut and maximum covariance analysis with a sample of women diagnosed wit h bulimia nervosa (n = 201) or women college students (n = 412). Indicators were derived from the Bulimia Test-Revised and the Eating Attitudes Test-2 6, and both a mixed sample and the nonclinical sample were analyzed. With b oth taxometric methods and both mixed and nonclinical samples, results were consistently suggestive of a latent taxon for bulimia. These results chall enge a dimensional model of bulimia nervosa.
