PHQ-9, GAD-7, and ASRS are short questionnaires that turn how you feel into a number we can track over time. PHQ-9 measures depression, GAD-7 measures anxiety, and ASRS screens for adult ADHD. Higher scores mean more symptoms, and falling scores mean treatment is working.
TL;DR: Mental health is not invisible. It is measurable. We use three short, evidence-based questionnaires to track depression, anxiety, and ADHD signals over time, the same way a primary care doctor tracks blood pressure. Feeling better is great. Knowing how much better is precision medicine.

What These Scores Actually Measure
These scores are simple self-reports that ask you to rate, on a small scale, how often certain symptoms have shown up in the last two weeks. They do not replace a real conversation with a clinician. They give that conversation a clear baseline and a way to measure change.
We use three:
- PHQ-9 for symptoms of depression.
- GAD-7 for symptoms of generalized anxiety.
- ASRS for signs of adult attention deficit hyperactivity disorder (ADHD).
Each one is short, well studied, and free of charge. The point is not the score itself. The point is the trend line. If we start a new treatment, we want to see the number move in the right direction. If it does not move, we change the plan.
PHQ-9: The Depression Score
PHQ-9 stands for the Patient Health Questionnaire-9. It is a nine-question check-in for depressive symptoms over the past two weeks. Think of it as a standardized way to put words around how heavy things have felt lately.
Each question is scored from 0 (not at all) to 3 (nearly every day), so the total can range from 0 to 27.
- 0 to 4: minimal or no symptoms.
- 5 to 9: mild symptoms.
- 10 to 14: moderate. Often the point where clinical attention helps.
- 15 to 19: moderately severe.
- 20 to 27: severe.
Our goal: not just to get you "out of the red." We aim for remission, which is a score under 5. There is also one specific question on the PHQ-9 about thoughts of self-harm, and any non-zero answer there always gets a direct conversation, not a letter or a portal message.
GAD-7: The Anxiety Score
GAD-7 stands for the Generalized Anxiety Disorder-7 scale. It is seven questions about worry, restlessness, irritability, and trouble relaxing over the past two weeks. The total runs from 0 to 21.
- 0 to 4: minimal anxiety.
- 5 to 9: mild.
- 10 to 14: moderate.
- 15 to 21: severe.
Why GAD-7 matters beyond mental health: high anxiety scores often show up disguised as physical complaints. Chest tightness that mimics heart trouble. Stomach pain or loose stools that look like irritable bowel syndrome (IBS). Insomnia that no sleep aid fully fixes. Treating the anxiety often quiets these "physical" symptoms because the nervous system finally settles down.
ASRS: The Adult ADHD Screen
ASRS stands for the Adult ADHD Self-Report Scale, developed with the World Health Organization. It is the screening tool we use for attention and focus issues in adults. It looks at two patterns:

- Inattention: trouble focusing, losing track of details, finishing tasks late.
- Hyperactivity and impulsivity: feeling restless, talking over people, struggling to sit still.
The screen has two parts:
- Part A: the first six questions. A high score here is the strongest signal that adult ADHD is worth a deeper look.
- Part B: the remaining questions. These show how much your symptoms are interfering with daily life.
Important: a high ASRS score suggests ADHD. It does not by itself diagnose it. We use the score as a starting point for a longer clinical interview that looks at history, school records, work patterns, and other conditions that can mimic ADHD, like sleep deprivation, untreated anxiety, or thyroid problems.
Why We Track Scores Over Time
We graph these scores at every visit. If we add a medication, change a dose, or start therapy, we should see the lines move within a few weeks. If they do not move, that is real information, not failure. It tells us to pivot, not push harder.
That is the difference between guessing and measurement-based care. The same logic that runs your A1c trend, your blood pressure log, or your cholesterol panel applies here.
Actionable Steps in Philly
Use these scores as a tool, not a verdict.
- Take the baseline: Fill out the PHQ-9 and GAD-7 at your next visit, even if you feel "fine." It gives us a starting line.
- Recheck every 4 to 6 weeks: After any change in treatment, repeat the score to see if it is moving.
- Pair the score with one real-life metric: Sleep hours, days you exercised, or how many times you canceled plans. Numbers plus story is the full picture.
- Speak up about question 9: On the PHQ-9, the last question asks about thoughts of self-harm. If that number is anything but zero, tell us. We respond with care, not alarm.
- Bring your wearable data: Resting heart rate, heart rate variability (HRV), and sleep quality often change before mood does. We look at all of it together.
Key Takeaways
- PHQ-9, GAD-7, and ASRS are tools, not labels. They turn how you feel into something we can track.
- Trends matter more than any single score. A score that drops from 18 to 9 is a win, even if it is not yet zero.
- Remission, not "less bad," is the goal. For PHQ-9 and GAD-7, we aim for under 5.
- A high ASRS is a starting point. Diagnosing adult ADHD takes a real conversation, not just a screen.
- Measurement-based care reduces guessing. If a treatment is not working, the numbers tell us early.
