Parents are always telling kids they need to be optimistic, but there hasn't been much evidence that optimism really does them any good. Looking on the bright side may even hurt teenagers, say some experts, because it can make them downplay the risks posed by smoking and drug abuse. That's in stark contrast to older adults, who are generally healthier and happier the more optimistic they are.
But researchers in Australia say that optimism may help protect teenagers against depression. That news, reported in the journal Pediatrics, could matter to many teens, since 10 to 15 percent of adolescents have symptoms of depression at any given time. Depression is a huge risk factor for suicide and increases the risk of substance abuse, trouble in school and relationships, and physical illness.
The researchers followed 5,634 Australian 12- and 13-year-olds for 18 months, asking them about their psychological state, substance abuse, and antisocial behavior. The more optimistic the students were, the less likely they were to become depressed. But there was just a modest effect on other common teen problems. For instance, optimistic teenagers were only slightly less likely to be involved in criminal activity or heavy substance abuse.
