USA Today has reported on yelling in the workplace and at home and why for many this is so prevalent. Past research has shown that roughly 88% of parents yell or shout (a thousand families were included in these findings) at their children.
An interesting tid-bit is that 100% of parents of 7 years-old admitted to yelling at their child often. Research has found that yelling at your kid is exhausting for both the yeller (mostly parents) and the receiver of the yelling (mostly kids).
