PHQ-2 Calculator
The PHQ-2 is a two-item, ultra-brief version of the PHQ-9 used to quickly flag whether a fuller depression screening may be worthwhile. It asks about the two core symptoms of depression: low mood and loss of interest or pleasure.
How the score is calculated
Each of the two items is scored 0–3 based on frequency over the last two weeks, for a total from 0 to 6. A score of 3 or more is commonly used as a threshold suggesting that a longer instrument, such as the PHQ-9, may be useful.
Important limitations
- The PHQ-2 is intentionally brief and is meant to flag the need for further screening — not to characterize severity in detail.
- A positive screen does not confirm depression; a negative screen does not rule it out entirely.
Frequently Asked Questions
What is the PHQ-2?
A two-question version of the PHQ-9 used as a quick first-pass depression screen.
What does a positive PHQ-2 screen mean?
It suggests that completing the full PHQ-9, or speaking with a healthcare professional, may be a helpful next step — not that a diagnosis has been made.
Should I take the PHQ-9 instead?
If you want a more detailed picture of depressive symptoms, the nine-item PHQ-9 provides more information than this brief version.
