(FOX NEWS) - As many as 80 percent of parents worldwide spank their children, according to a 2014 UNICEF report. But a meta-analysis of five decades of research published Wednesday in the Journal of Family Psychology suggests the disciplinary action can pose serious, long-term harm to children.
The research, which reviewed 160,000 children overall, linked repeated spanking to an increased risk of a child being defiant to his or her parents, anti-social, aggressive, mentally ill, and cognitively challenged.
