This study, conducted in Quebec, compared the rates of household psychological aggression and physical violence towards children, as reported by mothers in a telephone survey, between 1999 and 2004. Reports of minor physical violence towards a child by an adult living in the household decreased by 5% in 2004 compared to 1999. Reports of repeated psychological violence increased by 5%. Eighty percent of mothers reported the use of psychological aggression towards a child by an adult living in the household, 43% reported at least one episode of minor violence, and 6% reported at least one episode of severe physical violence. Attitudes favoring the use of violence for disciplinary purposes showed a significant decrease over the course of the study.
