The diagnostic validity of the 9-item PHQ-9 was established in studies involving 8 primary care and 7 obstetrical clinics. PHQ-9 scores > 10 had a sensitivity of 88% and a specificity of 88% for Major Depressive Disorder. Reliability and validity of the tool have indicated it has sound psychometric properties. See PHQ-9 Scoring on next page.

The Patient Health Questionnaire (PHQ-9) is a brief and valid screen for use in cancer populations. The PHQ-9 distinguishes both the presence and severity of depression. 27 The Generalized Anxiety Disorder (GAD-7) screen is another valid measure with low respondent burden that can be facilely integrated into routine history taking. 28
