Google is launching a new feature that's designed to help people dealing with depression.
Mobile users in the u-s who search for "clinical depression" will now be offered a clinically validated questionnaire called "PHQ-9".
The test asks about such items as energy, appetite and concentration levels.
Google says the test is a "private self-assessment" that determines whether users should seek professional help
The tech giant would not say how the test affects user privacy and data storage.
The national alliance of mental illness says about one in five Americans deal with clinical depression at least once in their lives.
But those with signs of depression typically wait six to eight years before seeking professional help.
