The primary aim of the present study was to examine whether the presence of borderline personality disorder (BPD) adversely impacted on outcome 3 years after treatment among women with bulimia nervosa (BN), in comparison to those women with either other personality disorders (other PD) or no personality disorder (no PD).
Participants were 134 women who received cognitive behaviour therapy for BN. The sample was divided into three groups: BPD (n=38), other PD (n=37), and no PD (n=59). Eating disorder (ED) symptoms and attitudes, and personality traits were examined at pretreatment assessment, 1 year and 3 year follow up.
At pretreatment assessment the BPD group had higher purging frequency, more comorbidity and poorer general functioning than the other PD and no PD groups. By 3 year follow up, however, no significant differences were found in ED symptomatology and general functioning among the groups. Pretreatment differences between the BPD and no PD groups on the personality measures of harm avoidance, self-directedness and cooperativeness disappeared over the course of 3 years.
Although women with BN and comorbid BPD appear more impaired at pretreatment assessment, they do not have poorer outcome than the other PD and no PD groups. The rate and level of improvement across the groups is not affected by the presence of BPD.
本研究的主要目的是，与患有其他人格障碍（其他PD）或无人格障碍（无PD）的神经性贪食症（BN）女性相比，检验边缘型人格障碍（BPD）的存在是否会对BN女性治疗3年后的结果产生不利影响。
134名接受BN认知行为疗法的女性参与了研究。样本分为三组：BPD组（n = 38）、其他PD组（n = 37）和无PD组（n = 59）。在治疗前评估、1年和3年随访时检查饮食失调（ED）症状和态度以及人格特质。
在治疗前评估中，BPD组比其他PD组和无PD组有更高的清除频率、更多的共病情况和更差的总体功能。然而，到3年随访时，各组之间在ED症状学和总体功能方面未发现显著差异。BPD组和无PD组在伤害回避、自我导向和合作性人格测量上的治疗前差异在3年过程中消失了。
尽管患有BN和共病BPD的女性在治疗前评估中似乎受损更严重，但她们的结果并不比其他PD组和无PD组差。各组的改善率和改善程度不受BPD存在的影响。
