How the result is read
The result is shown as PHQ-2, out of a maximum of 6.
The calculator reads each total as follows. Where a single answer changes the reading (for example sex, age or one extreme value), the working calculator says so.
| Total | Band | What the calculator says |
|---|---|---|
| 0 to 2 | Negative screen | Depression unlikely; re-screen if clinical concern. |
| 3 to 6 | Positive screen | Complete PHQ-9 + assess risk. ≥ 3 has good sensitivity for depression. |
