In the USA, when googling "depression" patients will be presented with a link to the PHQ-9 screening test.
Google has developed this in collaboration with the National Alliance on Mental Illness - and Ken Duckworth, the alliance's medical director, debates the merits of this approach with Simon Gilbody, from the Department of Health Sciences at the University of York.
Also joining this podcast is David Gilbert, mental health services user and director of InHealth Associates, who argues that it's only through patient involvement that real improvements to mental health can be obtained.
