Questionário de Saúde do Doente-9 (PHQ-9)
Enter the nine symptom-item frequencies for the preceding two weeks in the standard English PHQ-9 order. All nine responses are required for this summed-score method.
Clinical noticeThis clinical tool supports decision-making and does not replace individual medical assessment.
Context and use
Add the nine item scores to obtain a total of 0 to 27 points. The category is minimal (0–4), mild (5–9), moderate (10–14), moderately severe (15–19), or severe (20–27). The result describes symptom severity and does not by itself establish a depressive-disorder diagnosis.
