Parental hostility and parental depression are associated with childhood behavior problems, but these have been studied independently in the literature. This study examined the relationships between parental hostility and depression and childhood aggression and conduct problems. Parental hostility was hypothesized to predict children's current and future (two months later) aggression and conduct problems. Participants were primary caregivers of children 0 to 10 years of age. Results indicate that hostility is a better predictor of present and future childhood aggression and conduct problems than depression. Implications of this finding for preventing and treating childhood aggression and conduct problems are discussed.
