Interactive Administration (Optional)
Use this mode when the clinician says "start" or "administer" the PHQ-4.
- Confirm readiness and explain the past 2 weeks time frame plus the 0-3 response scale.
- Ask one item at a time (verbatim from the asset file) and wait for a response before continuing.
- Accept numeric or verbal responses; if unclear or out of range, ask for clarification.
- Record each response, compute the total score (0-12), and track depression/anxiety sub-scores.
- If the screen is positive, recommend PHQ-9 and/or GAD-7 for severity assessment.
- Offer a brief documentation summary if requested.
Clinical Workflow
