Child violence can have long-lasting causes and effects. Causes include poor parenting, negative environments, and exposure to abuse or violence. Effects may include depression, difficulties in school, and criminal behavior later in life. Witnessing or experiencing violence as a child can lead to lifelong problems like dropping out of school, unemployment, poverty, and depression. It may also cause anxiety and antisocial behaviors as the child feels on edge not knowing what to expect from situations or people. A significant portion of criminals and offenders experienced abuse or violence as children, which can teach violent behavior as a learned response.
