Fifty-eight normal-weight DSM-III-R bulimia nervosa patients were compared with 27 normal controls on measures of bulimia nervosa, depression, impulsivity, obsessionality and impulse control (dyscontrol) behaviours. Patients scored higher than controls on all these measures. Almost half the patient cohort met Lacey's multi-impulsive bulimia criteria. When bulimic symptoms were controlled for in an analysis of covariance, multi-impulsive bulimics did not score significantly differently to non-impulsive bulimics on psychometric measures of impulsivity, obsessionality and depression. The concept of impulsivity is critically reviewed and newer concepts linking obsessionality and impulsivity are explored.
对58名体重正常的DSM-III-R神经性贪食症患者与27名正常对照者进行了比较，比较内容涉及神经性贪食症、抑郁、冲动性、强迫观念及冲动控制（失控）行为的测量指标。在所有这些测量指标上，患者的得分均高于对照者。几乎一半的患者队列符合莱西的多重冲动性贪食症标准。在协方差分析中对贪食症状进行控制后，在冲动性、强迫观念和抑郁的心理测量指标上，多重冲动性贪食症患者与非冲动性贪食症患者的得分没有显著差异。对冲动性的概念进行了批判性回顾，并探讨了将强迫观念与冲动性联系起来的新观念。
