There has been debate as to whether bulimia represents the endpoint of an eating disorder continuum (the continuity hypothesis) or is categorically different from subthreshold bulimia or an absence of eating disorders (the discontinuity hypothesis). The present study tested whether differences among bulimic, subthreshold bulimic, and control women on weight-concern and psychopathology variables better accord with the continuity or discontinuity hypothesis. These 3 groups were compared on body mass, thin-ideal internalization, body dissatisfaction, dietary restraint, depressive symptoms, anxiety symptoms, and temperamental emotionality. Discriminant function analysis and follow-up pairwise contrasts indicated that the continuity hypothesis was supported for measures of both weight concern and psychopathology. Research and treatment implications of the continuity perspective are discussed.
关于神经性贪食症是代表饮食失调连续体的终点（连续性假说），还是与阈下神经性贪食症或无饮食失调有着本质区别（非连续性假说），一直存在争议。本研究检验了神经性贪食症患者、阈下神经性贪食症患者和对照女性在体重关注及精神病理学变量上的差异，是否更符合连续性或非连续性假说。对这三组人群在体重、对瘦的理想内化、身体不满、饮食限制、抑郁症状、焦虑症状和气质性情绪方面进行了比较。判别函数分析和后续的成对对比表明，体重关注和精神病理学测量结果均支持连续性假说。文中讨论了连续性观点对研究和治疗的启示。
