目的：探讨强迫症患者中不同类型的早年创伤、人格特质与临床症状三者之间的相互作用关系,以及适应不良的人格特质在早年创伤与强迫症状间的中介作用。方法：选取147例符合精神障碍诊断与统计手册第4版（DSM-IV）诊断标准的强迫症患者,使用耶鲁-布朗强迫症状量表（Y-BOCS）测量被试的强迫症状严重度,早年创伤问卷-自评版（ETI-SF）测量其早年创伤经历,NEO大五人格量表（NEO-FFI）测量其人格特质。结果：ETI-SF中情感虐待分量表得分与Y-BOCS总分呈正相关（r=0.19,P〈0.05）,NEO-FFI中神经质人格得分与Y-BOCS总分呈正相关（r=0.31,P〈0.001）,宜人性人格得分与Y-BOCS总分呈负相关（r=-0.18,P〈0.05）。通径分析显示神经质人格在情感虐待与强迫症状间起完全中介作用,中介作用大小为0.107（95%CI：0.04-0.19,P〈0.05）。结论：早年情感虐待可能与强迫症状呈正相关,而神经质人格在情感虐待与强迫症状之间发挥了完全中介作用。

英文摘要：

Objective： To explore the tri-relationship among the different types of early trauma, personality traits and obsessive-compulsive symptoms, and to analysis the mediating effects of maladaptive personality traits between early trauma and obsessive-compulsive symptoms. Methods： A total of 147 obsessive-compulsive patients were selected. The Yale-Brown obsessive-compulsive scale （Y-BOCS） was used to measure the degree of obsessive-compulsive symptoms, the Early Trauma Inventory Short Form （ETI-SF） was used to measure the early trauma experience, the NEO Five-Factor Inventory （ NEO-FFI ） was used to measure the personality characteristics. Results： The emotional abuse subscale scores of ETI-SF were positively correlated with the total scores of Y-BOCS （r = 0. 19; P 〈 0. 05）, the neuroticism scores of NEO-FFI were positively correlated with the to- tal scores of Y-BOCS （r =0. 31, P 〈0. 001）, while the agreeableness scores of NEO-FFI were negatively correlated with the total scores of Y-BOCS （r = -0. 18, P 〈0. 05）. The pathway analysis showed the indirect effects from emotional abuse to Y-BOCS via neuroticism were 0. 107 （95% CI： 0. 04 - 0. 19, P 〈 0. 05）, the neuroticism play a completely mediated role. Conclusion： Early emotional abuse may be positively correlated with obsessive-compulsive symptoms, while the neuroticism may play a completely mediating role between the early emotional abuse and obsessive-compulsive symptoms.
