The aim of the study was to examine the association between fathers’ prenatal psychological distress and children’s aggressive behaviour in terms of hitting others, and how children’s age, gender and temperament affect this association. The study is based on data from 20,155 fathers and mothers from the Norwegian Mother, Father and Child Cohort Study (MoBa). Fathers and mothers completed questionnaires at 17 or 18 weeks of gestation and mothers at children’s age 18 months, and 3 and 5 years. Fathers’ prenatal psychological distress was assessed by the 5-item Symptom Checklist (SCL-5), and children’s temperament by 12 items from the Emotionality Activity Sociability (EAS) Temperament Survey. Increasing prenatal psychological distress in fathers was associated with an increase of hitting from 18 months to 3 years of age in boys. Children’s temperament did not affect the association between fathers’ prenatal psychological distress and children’s aggressive behaviour.

该研究的目的是检查父亲产前心理困扰与孩子在打别人方面的攻击性行为之间的关联，以及孩子的年龄、性别和气质如何影响这种关联。该研究基于来自挪威母亲、父亲和儿童队列研究 (MoBa) 的 20,155 名父亲和母亲的数据。父亲和母亲在妊娠 17 或 18 周时完成问卷，母亲在孩子 18 个月、3 岁和 5 岁时完成问卷。父亲的产前心理困扰通过 5 项症状检查表 (SCL-5) 进行评估，儿童的气质通过情绪活动社交能力 (EAS) 气质调查的 12 项进行评估。父亲产前心理困扰的增加与男孩从 18 个月到 3 岁时打架的增加有关。
