Yet another study shows what should be obvious: teenagers need to spend time with dad. The study tracked over 200 families and found that time with both parents starts to decrease when kids reach the age of 15. But the University of Pennsylvania study also found that the time teens spend with their dads has critical benefits.

A CNN article stated, "The more time spent alone with their fathers, the higher their self-esteem; the more time with their dads in a group setting, the better their social skills." The article also said that time with mom helps too, but there's just something special about time with dad.

The researchers conjectured that one-on-one time with dad "may develop higher general self-worth [in teenagers] because their fathers go beyond social expectations to devote undivided attention to them."

The message is clear: dads can make a huge difference in their kids' lives.
