PHQ-9 and GAD-7 are the most-used validated symptom measures in outpatient behavioral health, and they are the two screeners that show up in payer-mandated MBC reporting most often. They are short, free to use, well-validated, and they survive a busy clinic day. They are also frequently captured poorly: scored inconsistently, stuck in the HPI as free text, or not trended at all.
This guide is the short version of how to use them well, in a way that supports both clinical work and the reporting your payers are starting to require.
When to administer
PHQ-9 and GAD-7 should be administered:
- At every new-patient intake.
- At every follow-up visit during active treatment of depression or anxiety.
- On a defined cadence (every visit or every other visit) for patients in maintenance phase.
- Before any major treatment change (medication initiation, dose change, regimen switch, course change).
- When the patient or family raises concern about symptom trajectory.
Most practices land on “every visit during active treatment, every other visit during maintenance.” That is a reasonable default.
How to administer
Two patterns work, and you can pick whichever fits your practice:
Pre-visit, on a tablet or via the patient portal. The patient completes the screener before the visit. Scores arrive in the chart and you discuss them in the room. Most efficient. Best for practices with a check-in workflow that can support it.
In the visit, by interview. You ask the questions during the visit. Slower, but more accurate for patients with literacy issues, language barriers, or cognitive concerns. Captures the patient’s interpretation of the question, which is often clinically informative.
Avoid the third pattern, “have the patient fill it out and the clinician glance at it without engaging,” because the screener becomes a checkbox rather than a clinical tool.
How to score
Scoring is straightforward. The validated cutoffs:
PHQ-9:
- 0-4: minimal depression
- 5-9: mild
- 10-14: moderate
- 15-19: moderately severe
- 20-27: severe
GAD-7:
- 0-4: minimal anxiety
- 5-9: mild
- 10-14: moderate
- 15-21: severe
PHQ-9 also includes a suicide-risk question (item 9). Any positive response to item 9 is a clinical event; document the C-SSRS or your standard risk assessment in response, regardless of the total score.
The total score is one input. The item pattern is another. Two patients with a PHQ-9 of 12 may have very different patterns. One with high scores on items 1-4 (mood, anhedonia, sleep, energy) tells a different story than one with high scores on items 7-9 (concentration, psychomotor, suicidality). Look at the items.
How to chart
The score should live in the chart as a structured field, not as a sentence in the HPI. Two reasons:
Trending. A structured score can be charted over time, both in the patient’s record and in your practice’s aggregate reporting. A free-text “PHQ-9 of 12” in the HPI cannot.
Reporting. Payer-mandated MBC reports query structured scores. They do not parse free text reliably.
In Nextvisit, PHQ-9 and GAD-7 (plus AUDIT, CRAFFT, PCL-5, and the practice-configurable list) live as structured fields. The score lands automatically when the responses are captured. The trend graph shows in the chart header. The aggregate reporting view rolls up across providers.
If you are not using a system that supports this directly, the next-best pattern is a dedicated section in your EHR template with score and date, separate from the HPI prose. Keep the format consistent across visits.
How to trend
A trend is more clinically useful than any single score. Watch for:
- Sustained improvement. Two consecutive scores down 5 or more points typically reflects clinically significant improvement, often the threshold for “responder.”
- Sustained worsening. Two consecutive scores up 5 or more points warrants a treatment plan revisit.
- Plateau at a partial response. Stuck at a moderate score (10-14) for 6 to 8 weeks despite an adequate trial. Usually the signal to consider augmentation or rotation.
- Disconnects. Score does not match clinical impression. Often informative. The patient may be functionally better but reporting symptoms that haven’t lifted, or vice versa. Worth discussing in the visit.
What MBC reporting looks like
Three of the largest commercial payers and seven state Medicaid programs require behavioral-health practices to report aggregate score trends quarterly. The format is typically:
- Number of patients screened in the quarter.
- Distribution of baseline scores.
- Percentage of patients with at least one follow-up score within 90 days of baseline.
- Distribution of change from baseline among patients with follow-up scores.
The reports want the data, not narrative. If your scores are structured, the report comes out of the data warehouse. If your scores are in free-text HPIs, the report is a manual chart review project.
A note on patient experience
Some patients dislike the screeners and find them mechanical. The best mitigation is to talk about the score in the room, briefly. “Your PHQ-9 is 14 today, up from 9 last visit. That tracks with what you described about sleep and energy. Let’s talk about whether we adjust the dose.” The screener becomes part of the clinical conversation rather than paperwork. Adherence and accuracy both improve.
