Abstract
The father–child interaction deserves attention during the COVID-19 epidemic. This study administrated the Child Anger Questionnaire and the SCL-90 Symptom Checklist to collect primary data from 1862 fathers of Chinese young children during the COVID-19 outbreak, examined the relation between young children’s anger and their fathers’ mental health, and verified whether the relation was moderated by the gender or the child number. The results demonstrated that the detection rate of anger among Chinese young children was 60.08%, the scores of SCL-90 factors of their fathers were significantly lower than the Chinese normal adult male norms and those of infant parents, and the anger of young children had a significant effect on their fathers’ mental health. Gender and child number moderated this relation. It is of great significance to strengthen the attention to the anger of young children and the mental health of fathers during the period of public health emergencies, and to promote the harmonious interpersonal relationship between young children and their fathers.
