77 percent of parents believe they have talked with their kids about proper online behavior, according to a national survey, but only 44 percent of youth ages 10 to 23 would agree. Apparently, a lot of that sage advice against sexting and cyberbullying is going in one ear and out the other!

Maybe it's because I just imposed a no texting/snapchatting/calling rule on my son's baseball team of 11- and 12-year-old boys during practices and games, but this survey of more than 1,000 kids and 1,000 parents intrigued me. Do parents really know how much time their kids are committing to social media and online communications?

The youth in the survey (funded by software security provider McAfee) were much more aware than parents of the dangers of posting sensitive information such as their social security numbers or the identities of who they are dating. Yet they were still more likely to post this kind of information without their parents knowing it.

Seven in 10 surveyed kids admitted to hiding online activities from their parents through a variety of methods such as using password-protected mobile phones. Two-thirds of surveyed kids had posted photos of themselves online, but only half of their parents knew that. A third of youth posted intimate or sensitive personal details of themselves online but little more than one in 10 parents were aware of that type of online activity.
