This study examined the relationships between father-child and mother-child relationships, marital discord, and children's aggression, emotionality, and self-esteem. Participants were 144 primary school students (78 male, 66 female), who completed a questionnaire that measured the extent of discordance and the child's self-esteem, emotionality, and aggression. Results revealed; marital discord affected the father-child relationship, the mother-child relationship, and the self-esteem of the child; the father-child relationship influenced the self-esteem of the child; the mother-child relationship affected the father-child relationship and the aggression of the child. These results suggest that the problematic issues of children are highly influenced by discordance between parents, and that these issues emerged as emotional problems through father-child discord, and as behavioral problems through mother-child discord.
