Depression screening by a nine item Patient Health Questionnaire PHQ 9 in adults FAQ

What is a PHQ-9 depression screening?
+

The Patient Health Questionnaire (PHQ 9) is a self-administered instrument used for diagnosing various mental disorders.  PHQ 9 is the depression module of PHQ with 9 items, considered a short scale with accurate detection of depression and assessment of its severity, which guides further treatment decisions.

How do you calculate PHQ-9?
+

The PHQ 9 score is calculated by assigning 0,1,2,3 for the respective responses starting from “not at all” to “nearly every day,” then adding them together for all the 9 items. Usually, the PHQ 9 score ranges from 0 - 27. The PHQ 9 score's interpretation is based on the cut-of value; the scores are divided into 4 cut points, like 5,10,15, and 20.

When do you use PHQ-9?
+

Depressive disorders are characterized by a gradual loss of interest in everything; this is one of the most important symptoms. A test instrument like PHQ 9 comes to the rescue at this point; it assesses the major symptoms of depression. That scoring will help you diagnose the severity of depression, and it also helps in the case of measuring the response to treatment.
