Learning more about clinical depression with the PHQ-9 questionnaire
Editor’s note:Now when you search for "clinical depression" on Google on mobile, you'll see a Knowledge Panel that will give you the option to tap “check if you’re clinically depressed”, which will bring you to PHQ-9, a clinically validated screening questionnaire to test what your likely level of depression may be. To ensure that the information shared in the PHQ-9 questionnaire is accurate and useful, we have partnered with the National Alliance on Mental Illness on this announcement. Please see a guest post from them below.
Clinical depression is a very common condition—in fact, approximately one in five Americans experience an episode in their lifetime. However, despite its prevalence, only about 50 percent of people who suffer from depression actually receive treatment. To help raise awareness of this condition, we’ve teamed up with Google to help provide more direct access to tools and information to people who may be suffering.
You may have noticed that in Google search results, when you search for depression or clinical depression in the U.S., you see a Knowledge Panel for the condition which provides general information about it, the symptoms, and possible treatment options. Today PHQ-9, a clinically validated screening questionnaire which can help identify levels of depressive symptoms is also available directly from the search result. By tapping “Check if you’re clinically depressed,” you can take this private self-assessment to help determine your level of depression and the need for an in-person evaluation. The results of the PHQ-9 can help you have a more informed conversation with your doctor.
Mental health professionals often refer to major depressive disorder as clinically significant depression or clinical depression. Clinical depression is a treatable condition which can impact many aspects of a person's life. The PHQ-9 can be the first step to getting a proper diagnosis.
Statistics show that those who have symptoms of depression experience an average of a 6-8 year delay in getting treatment after the onset of symptoms. We believe that awareness of depression can help empower and educate you, enabling quicker access to treatment. And while this tool can help, it’s important to note that PHQ-9 is not meant to act as a singular tool for diagnosis.
We hope that by making this information available on Google, more people will become aware of depression and seek treatment to recover and improve their quality of life.
