Depression Score PHQ-9 Calculator

What is the PHQ-9 Depression Score Calculator?

The PHQ-9 (Patient Health Questionnaire) is a clinically validated tool for assessing the severity of depression. It evaluates symptoms experienced over the last two weeks and provides a score to help guide diagnosis and treatment planning.

Why Use the PHQ-9 Depression Score Calculator?

Understanding the severity of depressive symptoms helps individuals and healthcare providers make informed decisions about seeking support or treatment. This tool offers a structured way to track symptoms and identify patterns in mental health.

How is the PHQ-9 Depression Score Calculated?

The PHQ-9 consists of nine questions, each scored based on how often symptoms were experienced in the past two weeks:

  • Not at all: 0 points
  • Several days: 1 point
  • More than half the days: 2 points
  • Nearly every day: 3 points

The total score is calculated by summing the points from all questions, and the severity of depression is interpreted as follows:

  • Minimal Depression: Total score 0–4
  • Mild Depression: Total score 5–9
  • Moderate Depression: Total score 10–14
  • Moderately Severe Depression: Total score 15–19
  • Severe Depression: Total score 20–27

Example Calculation

Inputs:
  Little interest or pleasure in doing things: More than half the days (+2 pts)
  Feeling down, depressed, or hopeless: Nearly every day (+3 pts)
  Trouble falling or staying asleep or sleeping too much: Several days (+1 pts)
  Feeling tired or having little energy: More than half the days (+2 pts)
  Poor appetite or overeating: Several days (+1 pts)
  Feeling bad about yourself or that you are a failure: Several days (+1 pts)
  Trouble concentrating on things such as reading or watching TV: More than half the days (+2 pts)
  Moving or speaking so slowly that others could notice: More than half the days (+2 pts)
  Thoughts that you would be better off dead or hurting yourself: Several days (+1 pts)

Calculation:
  Total Score = 2 + 3 + 1 + 2 + 1 + 1 + 2 + 2 + 1 = 15

Result:
  Depression Severity = Moderately Severe Depression

FAQs

Can the PHQ-9 diagnose depression?

While the PHQ-9 provides a structured way to assess symptoms, it is not a diagnostic tool. A healthcare provider should interpret the results alongside a clinical evaluation.

What should I do if my score indicates severe depression?

If your score is in the severe range, it’s important to reach out to a healthcare provider for support. They can recommend treatment options, such as therapy, medication, or lifestyle changes.

Can I use this tool to track my symptoms over time?

Yes, you can use the PHQ-9 periodically to monitor changes in your symptoms and evaluate the effectiveness of treatments or coping strategies.
