Recent studies show that teens who have a more optimistic attitude are less likely to be depressed than their peers. The study, which was published in Pediatrics, also found a slight link between an optimistic attitude and less predilection towards drug abuse and bad behavior.

Although the new research doesn't prove that optimism is directly related to a decrease in depression, evidence show that optimistic kids do a better job avoiding behavioral issues, especially those teens are especially vulnerable to.

The study's lead author, Dr. George C. Patton of Australia's Royal Children's Hospital said "Optimistic kids do better in avoiding emotional and behavioral problems during their teens, but it in no way makes them immune to setbacks. There are a whole lot of other skills and experiences that are also important in getting through life."

The study involves 5,634 children who started their involvement with the research when they were 12 to 14 years old. The kids were asked about how they viewed the future, the world around them, and themselves. Less optimistic kids don't usually recognize positive things about themselves or the world around them.

On the other hand, the kids who show that they were the most optimistic of the group showed half the risk of showing signs of depression. Optimistic young people also showed a "modest" link to antisocial behavior and less heavy substance abuse. Among the group of less optimistic teens, the rate of new cases of depression rises around 32% each year.
