This study investigated the global and specific cognitive style associated with bulimia nervosa. Three groups of women (women with bulimia nervosa, women with major depression, and controls) completed measures of eating disorder severity, depression, dysfunctional cognitions and irrational beliefs. The control group was found to report significantly lower levels of cognitive distortions and irrational beliefs overall than both women with bulimia nervosa and women with depression. However, no difference was found between the latter two groups. Furthermore, the pattern of individual cognitions and beliefs was exactly the same. When depression was statistically controlled, cognitive style no longer differentiated between the control group and two clinical groups. These results have implications for improving the effectiveness of cognitive behaviour therapy for bulimia nervosa.
本研究调查了与神经性贪食症相关的整体及特定认知风格。三组女性（神经性贪食症女性、重度抑郁症女性和对照组）完成了饮食失调严重程度、抑郁、功能失调认知和非理性信念的测量。结果发现，对照组报告的认知扭曲和非理性信念总体水平明显低于神经性贪食症女性和抑郁症女性。然而，后两组之间未发现差异。此外，个体认知和信念模式完全相同。当对抑郁进行统计学控制后，认知风格在对照组和两个临床组之间不再具有区分性。这些结果对提高神经性贪食症认知行为疗法的有效性具有启示意义。
