PHQ-9 vs GAD-7: What Standard Screeners Miss About Veteran Recovery
The PHQ-9 and GAD-7 remain the workhorses of mental-health screening, but for Veterans and first responders, symptom scores alone don't capture recovery. Here's what they leave out — and what to measure alongside them.
Ask any therapist working with Veterans or first responders which instruments they use most, and the PHQ-9 and GAD-7 will be near the top of the list. They're free, validated, quick to score, and embedded in nearly every EMR. That's the case for using them. The case against relying on them alone is quieter but just as important.
What the PHQ-9 and GAD-7 do well
Both screeners are strong at what they were designed for: detecting the presence and severity of depression and generalized anxiety in primary care. Cut-scores are well-established. Change over time tracks meaningfully with treatment response. For a first-line symptom check, they earn their keep.
Where they fall short for Veterans and first responders
Recovery in this population is rarely a symptom-only story. A Veteran can score a 7 on the PHQ-9 — "mild" — and still be unable to hold a job, sustain relationships, or leave the house without a plan. A paramedic can move from PCL-5 68 to PCL-5 32 and still be nowhere near ready to return to shift work.
Three specific gaps come up repeatedly in practice:
- Function isn't measured. Neither instrument asks about role performance, participation, or daily living capacity — the things a person, their family, and their employer actually notice.
- Moral injury is invisible. The PHQ-9 doesn't distinguish depressive symptoms driven by neurochemistry from those driven by guilt, shame, or a violated moral code — which demand very different clinical responses.
- Readiness isn't captured. Return-to-duty and return-to-work decisions require an assessment of capacity under load, not a symptom checklist taken in a quiet office.
What to measure alongside them
A more complete picture needs domain-level signals that sit next to symptom scores rather than replacing them. In practice, that means tracking six things weekly:
- Recovery — subjective wellness trend
- Function — capacity to perform daily and occupational tasks
- Reintegration — social and family participation
- Readiness — capacity under expected operational load
- Purpose — sense of meaning and direction
- Participation — actual engagement in valued activities
None of these replace the PHQ-9 or GAD-7. They contextualize them. A rising PHQ-9 alongside falling function tells a different story from a rising PHQ-9 with stable function — and warrants a different clinical response.
Symptom scores tell you how someone feels this week. Function and participation tell you what their life looks like. You need both.
Bottom line
Keep the PHQ-9 and GAD-7. They still do their job. But treat them as one input into a multi-domain recovery picture, not the whole picture. For populations whose recovery is defined by return to role and community — Veterans, first responders, injured workers — the domains outside the questionnaire are usually the ones that determine outcome.
