Understanding Your PHQ-9 and GAD-7 Scores (And Why 'Moderate' Can Still Mean Severe)

The PHQ-9 asks how often, over the last two weeks, you've been bothered by nine things: low interest or pleasure, feeling down, sleep problems, low energy, appetite changes, feeling bad about yourself, trouble concentrating, being slowed down or restless, and thoughts of being better off dead or hurting yourself.

Each item is scored 0 (not at all) to 3 (nearly every day). The total ranges from 0 to 27.

The GAD-7 uses the same two-week window and the same 0-to-3 scale, across seven items: feeling nervous, being unable to stop worrying, worrying too much about different things, trouble relaxing, restlessness, irritability, and feeling afraid something awful might happen.

The total ranges from 0 to 21.

These questionnaires aren't a test you pass or fail, and they aren't the basis for your diagnosis. They serve three purposes.

• Screening. They flag when someone should be evaluated further.
• Baseline. They give a starting point so progress can be measured. This matters enormously for treatments where change happens quickly and needs to be tracked objectively.
• Tracking. Repeated scores over time show whether treatment is working. A drop from 13 to 4 is meaningful. A score that sits at 13 for six months while you cycle through medications is meaningful too, in a different way.

In depression research and in TMS clinics, remission is typically defined as a PHQ-9 score below 5. Not "a little better." Below 5. That's the target.

SAINT (Stanford Accelerated Intelligent Neuromodulation Therapy) is an accelerated, FDA-cleared form of TMS developed at Stanford's Brain Stimulation Lab. It's indicated for adults with major depressive disorder who haven't gotten adequate relief from antidepressants in their current episode, which is another way of saying: people whose scores haven't moved.

In the clinical trials behind its clearance, 79 percent of participants reached remission, with an average time to remission of 2.6 days. Across more than 400 trial patients, 85 percent experienced symptom relief, with no serious adverse events. For comparison, remission rates in similar treatment-resistant populations run about 14 percent for another medication trial and 17 to 32 percent for standard TMS.

Here's how it works at a Verified SAINT Provider like Neuro Wellness TMS Centers of America:

1. Consultation (Zoom web conference). You meet with our clinical team over a convenient Zoom call. As your evaluation evolves, you will also have the option to meet with our psychiatrist by Zoom web conference or in person at our clinic. You meet with our clinical team, complete a fresh PHQ-9 and GAD-7 for a baseline, and review your full history to confirm you're a candidate.
2. fMRI brain scan (mandatory in person). A roughly 45-minute functional MRI maps how your individual brain networks are wired. (Mandatory in-person scan at an imaging partner center.)
3. Personalized targeting. A targeting algorithm reads your scan and identifies the exact location for stimulation. Neuronavigation guides the coil to that spot for every session.
4. Five-day stimulation series (mandatory in person). In-person treatment Monday through Friday at our Coral Springs clinic. Ten 10-minute sessions per day, with 50-minute breaks in between, for five consecutive days. Five clinic visits, compared with 30 to 36 for conventional TMS. Your scores are tracked throughout, so you and your care team can see the change as it happens.

Side effects were generally mild in trials: headache, fatigue, and temporary scalp discomfort. SAINT isn't appropriate for people with non-removable metal in or near the head or an implanted device, and you'll be screened at your consultation. You don't have to stop your current medications; most patients continue their existing regimen.

If you've been watching your scores plateau, or if the gap between your "moderate" number and how you actually feel has been bothering you, bring that to a consultation.

At Neuro Wellness TMS Centers of America, the first appointment is an evaluation, not a commitment. We use these tools the way they're meant to be used: as a starting point for a conversation, not a verdict. We'll review your scores alongside your full history and tell you honestly whether SAINT is likely to move them. We offer private outpatient care with a dedicated care team and weekend availability. Insurance coverage varies by plan; our team can help you understand your options, including prior authorization and self-pay.
