The National Alliance on Mental Illness on Wednesday announced that Google on mobile now provides people who search for the term "clinical depression" with a direct link to the PHQ-9 questionnaire used by medical professionals in the United States to evaluate patients for the disorder. People can conduct a self-assessment by filling in the questionnaire online. When someone conducts a Google search on mobile for information on "clinical depression," a link to "check if you're clinically depressed" will appear in the depression knowledge panel.
