Fathers’ Mental Health and Children’s Aggressive Behaviour A Study Based on Data from the Norwegian Mother, Father and Child Cohort Study (MoBa)

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.
