While his source is from Yahoo, this comes from a larger study called a meta-analysis which, simply put, looks at multiple scientific studies and makes conclusions. Here's a better summary. Of the 14 antidepressants studied, only one was found to be effective in comparison to a placebo (sugar pills). This isn't news though; it's been known that most antidepressants aren't as effective in teens. Some studies have even said they're dangerous.

I believe in antidepressants, I know they've saved many of my friends lives. But this does say that we need more research on their efficacy in young folks, particularly for how frequently they're prescribed. If we find that it's a curve and that effectiveness goes up in age, by overprescribing as teens, we may be doing more damage by making people think that they're unhelpful and not turning to treatment later in life. There's just a lot more research to be done.
