What your weekly score actually tells you
It's not a grade, a diagnosis, or a verdict. It's a dot on a chart — and the chart is the point.
Once a week, Nagi asks you eight short questions about how the last while has actually been — sleep, energy, interest, mood — and turns your answers into a number. The scale has a name, the Lumetrix S8 PROM (a "patient-reported outcome measure", which is clinical language for you describing your own experience, structured). Seven of the eight questions score your S8 — a depression-focused score from 0 to 28 — and the eighth tracks anxiety alongside it, separately, so one number never muddles two different things.
If you've ever looked at that number and felt judged by it, this article is for you, because a score like this is one of the most misread objects in all of wellbeing. Read the right way, it's quietly useful. Read the wrong way, it's just a small weekly opportunity to feel bad.
So let's read it the right way.
One number is almost meaningless. That's fine.
Your score on any single week is a snapshot, and snapshots are noisy. A rough night before you answered, a cold coming on, a hard conversation that morning — all of it leaks into the number. Clinicians who use questionnaires like this professionally know that, which is why no good one treats a single result as an answer to anything. It's a reading, the way one temperature reading isn't a climate.
This means two things you should genuinely internalise. A bad score on a bad week is not news — it's the questionnaire noticing what you already knew. And a score that jumps around a bit week to week is normal, not a malfunction of you.
The direction is the information
What the weekly score is actually for is the thing no single week can show: direction. Four or five dots start to make a line, and the line answers questions the number can't. Is this a dip or a slope? Did that change you made — the earlier nights, the walking, the medication your doctor started — land anywhere visible? Is December always like this for you, or was last year different?
That's also why answering honestly matters more than answering "well." The score has no opinion of you and nobody is marking it. Its entire value is accuracy: an honest 18 is useful, a flattering 11 is noise you've paid for with the truth.
What the score is not
It isn't a diagnosis — Nagi doesn't diagnose anything, and no questionnaire score, anywhere, is a diagnosis on its own; even in a clinic these tools are conversation-starters, not verdicts. It isn't a grade — there's no pass mark and no failing. And it isn't a prediction — it describes the week you just had, not the one coming.
It's also not private-in-the-scary-sense: your scores live in your Nagi account, which isn't connected to your name — so the honest answer costs you nothing anywhere else in your life.
The one time the number itself matters
Trends beat snapshots — with one exception. If your scores have been climbing for several weeks in a row, or a week's answers reflect things that worry you, that's the chart telling you it's time to bring a human into the loop: a GP, a therapist, someone you trust. Your report exists for exactly that moment — a doctor can do far more with six weeks of honest dots than with "I've been feeling bad lately." The score's highest purpose isn't to measure you. It's to help you arrive at the right conversation early, with evidence in hand.
The rest of the time: answer honestly, glance at the line, and let the number be what it is — one dot, doing its small, patient job.
