Some women experience thoughts of harming their infants during the early postpartum period. These intrusive thoughts are conceptually similar to obsessive-compulsive disorder. The aim of our study was to assess whether personality characteristics may predict a mother's development of postpartum thoughts of harming her infant.
We studied 137 women with no psychiatric history. They were assessed at two different times during the postpartum period (2-3days after giving birth and during the 8th week following delivery). We assessed postpartum thoughts of harming one's infant with a semi-structured interview conducted in person. Personality characteristics were assessed with the Eysenck Personality Questionnaire. Depression was assessed with the Edinburgh Postnatal Depression Scale and with a structured interview (Diagnostic Interview for Genetic Studies). We also assessed socio-demographic variables, obstetric variables and stressful life events. Adjusting for age, depression and stressful life events, logistic regression was conducted to explore the relationship between a woman's personality characteristics and postpartum thoughts of harming her infant.
Women with postpartum thoughts of harming their infants scored higher in EPQ-Psychoticism (P=0.003) but not in neuroticism or extraversion. EPQ-Psychoticism was significantly associated with the presence of postpartum intrusive thoughts (OR=1.67, p=0.003) after adjusting for other personality dimensions, age, depression and life stress. Those women scoring 5 or higher in EPQ-Psychoticism were 5.5 times more likely to report postpartum intrusive thoughts (p=0.004).
In healthy women without psychiatric history, psychoticism is a predictor of postpartum thoughts of harming their infants.
一些女性在产后早期会出现伤害婴儿的想法。这些侵入性想法在概念上与强迫症相似。我们的研究旨在评估人格特征是否可以预测母亲产后伤害婴儿的想法。
我们研究了 137 名没有精神病史的女性。她们在产后的两个不同时间点（分娩后 2-3 天和分娩后第 8 周）接受评估。我们通过面对面的半结构化访谈评估产后伤害婴儿的想法。人格特征使用艾森克人格问卷进行评估。抑郁使用爱丁堡产后抑郁量表和结构化访谈（遗传研究诊断访谈）进行评估。我们还评估了社会人口统计学变量、产科变量和生活应激事件。调整年龄、抑郁和生活应激事件后，进行逻辑回归以探索女性人格特征与产后伤害婴儿想法之间的关系。
有产后伤害婴儿想法的女性在 EPQ-精神质（P=0.003）方面得分更高，但在神经质或外向性方面没有差异。在调整其他人格维度、年龄、抑郁和生活压力后，EPQ-精神质与产后侵入性想法的存在显著相关（OR=1.67，p=0.003）。那些 EPQ-精神质得分在 5 或以上的女性报告产后侵入性想法的可能性是得分在 5 或以下的女性的 5.5 倍（p=0.004）。
在没有精神病史的健康女性中，精神质是产后伤害婴儿想法的预测因素。
