PHQ-2

Two-item depression screening tool.

Intended population: Adult primary-care screening over the last two weeks.

Screening scores support an interview; they do not establish a diagnosis or determine treatment.
Assess safety directly when there is any concern; a negative screen does not exclude suicide risk.

Over the last 2 weeks: Little interest or pleasure in doing things

Over the last 2 weeks: Feeling down, depressed, or hopeless
