Jon Fingas, writing for Engadget:

Only half of Americans who face depression get help for it, and Google is determined to increase that percentage. As of today, it’s offering a medically validated, anonymous screening questionnaire for clinical depression if you search for information on the condition. This won’t definitively indicate that you’re clinically depressed, to be clear, but it will give you useful information you can take to a doctor. And importantly, the very presence of the questionnaire promises to raise awareness and promote treatment beyond what a basic information card would offer.
