Lifetime comorbidity of alcohol dependence in women with bulimia nervosa.

To determine how women with comorbid bulimia nervosa and alcohol dependence differed from those with bulimia nervosa alone, 114 women with DSM-III-R bulimia nervosa were assessed at intake for a randomized clinical trial with structure diagnostic interviews and psychometric instruments. The sample was divided on the basis of the presence (47%) or absence (53%) of lifetime alcohol dependence. Axis I and Axis II disorders, clinical features of bulimia, and personality and temperament characteristics were then compared. Women with comorbid alcohol dependence and bulimia nervosa reported a higher prevalence of suicide attempts, anxiety disorders, other substance dependence, conduct disorder and personality disorders (especially borderline and histrionic), and higher scores on novelty seeking, impulsivity, and immature defenses. There were few differences in the severity of bulimic symptoms. Findings revealed that women with comorbid bulimia nervosa and alcohol dependence bear a greater burden of Axis I and Axis II psychopathology and display greater symptoms of impulsivity and novelty seeking.
