PHQ-4 anxiety and depression check
Four questions combining the two core anxiety items (GAD-2) and the two core depression items (PHQ-2). A very short first check that points to the fuller GAD-7 or PHQ-9 when either part is raised.
This is a screening questionnaire, not a diagnosis. If you are in danger right now, contact your local emergency number or see the crisis page.
