The results of past research suggest the possible existence of a distinct subgroup of bulimic individuals who display multiple behaviors indicative of impulsivity (e.g., stealing, self-injury, attempted suicide, drug abuse). We further investigated potential relationships between multi-impulsivity and other clinical variables.
We compared women with bulimia nervosa (purging type) who displayed "multi-impulsivity" (n = 40) to those who did not (n = 177) with regard to symptom history and presentation, eating-disordered attitudes, and sexual experience.
The two groups did not differ in mean age, body mass index, scores on scales of eating-disordered attitudes and traits, incidence of self-induced vomiting, sexual intercourse, or masturbation, and current frequency of binge eating and self-induced vomiting. However, relative to the comparison group, women in the multi-impulsive group reported earlier onset of binge eating and sexual intercourse, a greater incidence of laxative abuse, and use of a greater number of different substances. There were statistical trends (p < .10) toward the multi-impulsive group displaying earlier onset of self-induced vomiting, laxative abuse, and masturbation.
Results are discussed in relation to the results of past research and the implications for treatment of bulimic women.
过去的研究结果表明，可能存在一个明显的暴食症患者亚组，他们表现出多种冲动行为（如偷窃、自我伤害、自杀未遂、药物滥用）。我们进一步研究了多重冲动与其他临床变量之间的潜在关系。
我们比较了神经性贪食症（清除型）女性中表现出“多重冲动”的患者（n = 40）和未表现出该症状的患者（n = 177）在症状史和表现、饮食失调态度以及性经历方面的差异。
两组在平均年龄、体重指数、饮食失调态度和特质量表得分、自我催吐发生率、性交或自慰情况以及当前暴饮暴食和自我催吐频率方面没有差异。然而，与对照组相比，多重冲动组的女性报告称暴饮暴食和性交的发病时间更早，滥用泻药的发生率更高，使用的不同物质种类更多。多重冲动组在自我催吐、滥用泻药和自慰的发病时间上有统计学趋势（p < .10）。
结合过去的研究结果以及对暴食症女性治疗的影响对结果进行了讨论。
