More than 35 percent of adults worldwide have witnessed a parent become physically or verbally abusive towards a coach or official at a children's sporting event, according to a joint Reuters/Ipsos poll. The survey of 23,000 adults in 22 countries by market research company Ipsos showed that irate, screaming, over-enthusiastic parents are not only found in Hollywood films and on television. People living in the United States (60 percent) were most likely to witness unsavory behavior by a parent followed closely by residents of India (59 percent), Italy (55 percent), Argentina (54 percent), Canada (53 percent) and Australia (50 percent). But people in Hungary, the Czech Republic, Mexico, Japan and France were the least likely to see parents behaving badly while their children played sports. According to the survey, men (41 percent) were more likely than women (33 percent) to have witnessed abusive behavior.
