We assessed \nthe lifetime prevalence of the \ncomponent bulimic behaviours and DSM-IV and DSM-III-R BN. Latent class\n analysis of nine \nseparate bulimic symptoms was used to develop an empirical typology of\n bulimic behaviour.<\/jats:p><jats:p><jats:bold>Results.<\/jats:bold> Although the lifetime prevalences of bingeing \n(23\u00b76%) and vomiting (4\u00b78%) were relatively \ncommon, DSM-IV BN was distinctly uncommon (0\u00b75%). The criterion\n \nthat specified the frequency \nand duration of bingeing and vomiting was an important limiting \ncondition. Analysis of alternative \nthresholds found little support for the DSM-IV thresholds requiring \nan average of twice per week \nfor 3 months. Latent class analysis yielded an interpretable four class\n \nsolution that had little overlap with the DSM-IV typology.<\/jats:p><jats:p><jats:bold>Conclusions.<\/jats:bold> As in other studies of unselected samples of \nwomen, the lifetime presence of bulimic \nbehaviours are relatively high. Our results suggest that the DSM-IV approach\n to categorizing \nbulimic behaviour inadequately captures the spectrum of lifetime \n bulimic behaviours in the general population.<\/jats:p>","DOI":"10.1017\/s0033291798006576","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:33:33Z","timestamp":1027776813000},"page":"599-610","source":"Crossref","is-referenced-by-count":90,"title":["The epidemiology and classification of bulimia nervosa"],"prefix":"10.1017","volume":"28","author":[{"given":"P.
