Despite much knowledge of the effects of maternal psychopathology on bonding, the effects of personality have received less attention. We aimed to examine the association between maternal personality and postnatal bonding disorder.
We analyzed data from 15,654 women who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Personality was assessed in middle pregnancy using the short-form Eysenck Personality Questionnaire-Revised, with the score for each subscale categorized into four levels. Bonding disorder was defined as the Mother-to-Infant Bonding Scale score of ≥5 one month after delivery. Multiple logistic regression analyses were conducted to examine the association between personality and bonding disorder after adjusting for age, education, parity, feelings towards pregnancy, social isolation, as well as the Edinburgh Postpartum Depression Scale (EPDS) score.
Higher extraversion was associated with a decreased risk of bonding disorder (p for trend <0.001). Higher neuroticism was associated with an increased risk of bonding disorder (p for trend <0.001), and this association disappeared after further adjustment for EPDS score (p for trend 0.39). No association between psychoticism and bonding disorder was observed (p for trend 0.83), and the association appeared after further adjustment for EPDS score (p for trend 0.0017). Higher lie was associated with a decreased risk of bonding disorder (p for trend <0.001).
Maternal personality and bonding were self-reported.
Lower extraversion, higher psychoticism, and lower lie were associated with bonding disorder. The association between higher neuroticism and bonding disorder was explained by postnatal depressive symptoms.
尽管人们对产妇精神病理学对母子联系的影响有了很多了解，但对人格的影响关注较少。我们旨在研究产妇人格与产后母子联系障碍的关系。
我们分析了参加东北医疗巨量数据库母婴三代队列研究的 15654 名女性的数据。人格在妊娠中期使用短式艾森克人格问卷修订版进行评估，每个子量表的分数分为四个水平。产后母子联系障碍定义为产后一个月时母婴联系量表的得分≥5 分。进行多因素逻辑回归分析，以在调整年龄、教育程度、产次、对怀孕的感受、社会孤立以及爱丁堡产后抑郁量表（EPDS）评分后，研究人格与母子联系障碍之间的关系。
较高的外向性与降低的母子联系障碍风险相关（趋势 p<0.001）。较高的神经质与增加的母子联系障碍风险相关（趋势 p<0.001），而在进一步调整 EPDS 评分后，这种关联消失（趋势 p=0.39）。精神病质与母子联系障碍之间无关联（趋势 p=0.83），且在进一步调整 EPDS 评分后，关联出现（趋势 p=0.0017）。较高的谎言分数与降低的母子联系障碍风险相关（趋势 p<0.001）。
母亲人格和母子联系是自我报告的。
较低的外向性、较高的精神病质和较低的谎言与母子联系障碍有关。神经质与母子联系障碍之间的关联可以用产后抑郁症状来解释。
