The questionnaire consists of nine questions, each corresponding to the nine diagnostic criteria for major depressive disorder as outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). These criteria include feelings of sadness or anhedonia (loss of interest or pleasure) and other associated symptoms like changes in appetite, sleep patterns, energy levels, concentration, feelings of worthlessness, and thoughts of death or suicide.

Each question on the PHQ-9 is scored on a scale from 0 to 3, with the total score ranging from 0 to 27. The scores are then interpreted as follows:

  1. 0-4: Minimal or no depression
  2. 5-9: Mild depression
  3. 10-14: Moderate depression
  4. 15-19: Moderately severe depression
  5. 20-27: Severe depression

The PHQ-9 is not only used for screening and diagnosis but also for monitoring the severity of depressive symptoms over time. It is commonly employed in primary care settings, mental health clinics, and research studies to identify individuals who may require further evaluation or intervention for depression.
