Despite the longstanding theoretical association in the attachment literature between maternal trauma history and disturbances in the mother–infant interaction, few studies have investigated mechanisms of transmission of traumatogenic relational patterns in high‐risk mother–infant dyads. This study investigated interrelationships among maternal trauma history, distorted maternal representations (DMRs, i.e. disturbed thoughts and feelings about the infant and self‐as‐parent), maternal mentalisation (i.e. capacity to conceive of self and other's intentions in terms of mental states including thoughts, feelings, and desires), and quality of interaction in a clinical sample of mothers with Borderline Personality Disorder (BPD) features and their infants (N = 61). Measures used included the Childhood Trauma Questionnaire, Parent Development Interview, Mother–Infant Relationship Scale, Borderline Symptom Checklist‐23, and the Emotional Availability Scales. The results indicated BPD features mediated the relationship between maternal trauma history and DMRs predicting disturbance in interaction. In addition, analyses showed that maternal mentalisation had a buffering effect between DMRs and maternal non‐hostility and yet the severity of BPD features moderated the relationship between mentalisation and DMRs. The findings suggest postpartum borderline pathology may adversely impact the experience of being a parent for women with a relational trauma history including deficits in mentalisation (i.e. hypermentalising) and disturbances in the mother–infant interaction. Implications for research and clinical practice are discussed.

评估高危人群的早期关系障碍：边缘人格障碍特征，孕产妇精神状态和观察到的相互作用。

尽管依恋文献中孕产妇外伤史与母婴互动障碍之间存在长期的理论联系，但很少有研究调查高危母婴二倍体中致创伤性关系型的传播机制。这项研究调查了孕产妇创伤史，畸形的孕产妇表征（DMR，即对婴儿和自己的父母的想法和感受），孕产妇的心理化（即，在包括思想在内的精神状态方面能够自我和他人意图的能力）之间的相互关系。 ，感觉和欲望）以及具有边缘性人格障碍（BPD）特征的母亲及其婴儿的临床样本中的互动质量（N = 61）。所使用的措施包括儿童创伤问卷，父母发展访谈，母婴关系量表，边界症状清单23和情绪可获得量表。结果表明，BPD功能介导了孕产妇外伤史与预测交互作用障碍的DMR之间的关系。此外，分析表明，孕产妇心理状况对DMR和孕产妇非敌对情绪具有缓冲作用，而BPD特征的严重性却缓和了心理状况与DMR之间的关系。研究结果表明，产后交界性病理可能会对有相关创伤史的女性做父母的经历产生不利影响，包括有精神障碍（即过度心理）和母婴互动障碍。
