A study reviewed more than two decades of research on the effects of spanking and found nothing positive to report, only that physical punishment leads to depression and anxiety.
That the use of physical punishment to discipline kids is a heated topic goes without saying. Over the last 20 years, many countries have passed laws to protect children from physical punishment in school and elsewhere, but the research shows that many parents still use it to discipline their kids.
A new Canadian study reviewed two decades of research on spanking and found not only that "...no study has found physical punishment to have a long-term positive effect, and most studies have found negative effects."

Depression, aggression, anxiety, feelings of hopelessness, drug and alcohol use, and "general psychological maladjustment." were among the problems seen in children who were spanked. As children who have been spanked become adults, they are more likely to become aggressive themselves since they have seen adults solving problems aggressively. According to the authors, "...virtually without exception, these studies found that physical punishment was associated with higher levels of aggression against parents, siblings, peers, and spouses."
