Which is a 9-item depression measure?

Explanation:
The main idea here is identifying which tool is a 9-item depression measure. The PHQ-9 fits this exactly: it contains nine questions that map to the DSM-5 symptoms of depression. Each item asks about how often a person has been bothered by a specific symptom over the past two weeks, scored from 0 (not at all) to 3 (nearly every day). Adding the items gives a total score from 0 to 27, with higher scores indicating more severe depressive symptoms. It’s brief, self-administered, and widely used in clinical settings to screen for depression and monitor change over time. Other options aren’t nine-item depression measures. The PHQ-2 uses only the first two items of the PHQ-9, so it’s just a quick screener, not the full 9-item assessment. The GAD-7 targets anxiety, not depression. The Beck Depression Inventory has 21 items, making it much longer than nine.
