Teens 'mocked' by their parents are at greater risk for bullying, victimization. New evidence suggests that adolescent bullying and victimization may have origins in the home. Many bullies have parents who are hostile, punitive and rejecting.

Derisive parenting precipitates a cycle of negative affect and anger between parents and adolescents, which ultimately leads to greater adolescent bullying and victimization. Source 7u.
