反映能力与边缘性人格特征:述情障碍的中介效应

Alexithymia as a Mediator Between Reflective Function and Borderline Personality Traits

目的:研究反映能力和边缘性人格特征的关系,以及述情障碍在二者之间的中介作用。方法:采用反映能力问卷中文版、米氏边缘人格检测量表、多伦多述情障碍量表对206名心理科门诊就诊患者进行测量。结果:(1)边缘性人格障碍倾向组的反映能力显著低于非边缘性人格障碍倾向组,反映能力与边缘性人格特征呈显著负相关(r=-0.300,P<0.01);(2)反映能力对边缘性人格特征不仅具有直接效应,还可通过述情障碍间接作用于边缘性人格特征,述情障碍的中介效应占总效应的40.3%。结论:边缘性人格倾向患者存在心智化功能的缺损,且述情障碍在反映能力和边缘性人格特征关系中存在部分中介作用。

Objective： To examine the relationship between reflective function and Borderline personality disorder （BPD） traits, and to explore the mediating role of alexithymia in the relation between reflective function and BPD traits among counseling patients. Methods： 206 counseling patients completed the Chinese Version of Reflective Function Ques- tionnaire（RFQ-C）, the McLean Screening Instrument for Borderline Personality Disorder（MSI-BPD） and 20-item Toronto Alexithymia Scale（TAS-20）. Results： （1）Patients with BPD traits had significantly lower total scores of RFQ than patients without BPD traits. Reflective function was negatively correlated with BPD traits（r=-0.300, P〈0.01）; （2）The relation between reflective function and BPD traits was partially mediated by alexithymia, accounting for 40.3% of the reflective func- tion to BPD traits. Conclusion： This study eonfirms previous studies indieating impairments of reflective function in patients with BPD traits and support the notion that reflective function exerts its influenee on BPD traits through the mediating role of alexithymia.
