As a reference for our Registrants, the National Register wanted to provide a copy of the Patient Health Questionnaire (PHQ-9), a mental health questionnaire that is often used by primary care providers to perform initial screenings for depression. It should be helpful for psychologists to have knowledge of this screening tool and to understand the scoring. While this is the most commonly used screening tool by primary care medical providers, it is not a diagnostic instrument on its own and should only be used as a component of a comprehensive mental health examination.

The New York Times also published an article regarding screening for depression based on the “Recommendations for Screening for Depression in Adults” editorial in JAMA.
