US Preventive Services Task Force,
2003 statement supporting screening for depression:
(We) recommend screening adults for depression in clinical practices that have systems in place to assure accurate diagnosis, effective treatment, and follow-up.
The first two questions of the PHQ-9 have been validated as a sensitive way to screen for depression
The PHQ-9-9 is used in two different ways. Initially to assess patients for depression and subsequently to monitor treatment progress should a formal DX of depression be made.
When assessing patients the score of the first two questions will determine whether or not you would need to go forward with the remaining questions. For example if the first two questions score as two or less you will be notified that the patient has screened negative for depression. For patient with a diagnosis of depression all other questions should be answered regardless of score in the first two question.
