Science & Transparency

The FCI is a measurement instrument in development. This page describes what it builds on — and, just as clearly, what has not yet been demonstrated.

What the FCI builds on

Function, not symptomsSymptom scales and functional capacity are not the same thing. The FCI consistently measures function.

Established measurement traditionsThe three channels draw on long-established research fields: performance measurement from attention and vigilance research, rest-activity metrics from chronobiology, and ecological momentary assessment for everyday self-report.

Within-person comparisonEach person is their own reference. Methodologically more robust — and fairer — than any comparison against norms.

Where we stand — declared openly

Dynergia is in its feasibility phase (Phase 0). Concretely:

No completed clinical validation studies of the FCI exist.
No patient data is currently being collected.
Any study involving patients will take place only after approval by the competent cantonal ethics committee (BASEC).
We make no efficacy claims before evidence exists — including in sales material.

The validation programme is designed and staged: methodological review, a field study under ethics approval, publication of the results — whatever they show.

How we audit ourselves

Our audit machinery runs before the study begins. The pilot's measure of success is defined in advance — not interpreted after the fact. The measurement's error margins are quantified and re-computed by hand by two independent parties. Whether an individual metric enters the score is decided by a rule signed before the data exists. Dropouts and interruptions are analysed according to a fixed plan — not however it suits afterwards. And where the data is insufficient, the system marks the week as not scorable instead of inventing a number.

To test whether the FCI measures more than established symptom questionnaires, the pilot study collects the PHQ-8 monthly — deliberately without the suicidality item, because an unmonitored digital channel cannot responsibly carry it, and strictly separated from the product: it appears in no report.

Our commitment

Limitations are documented, not airbrushed. Where the data does not support a statement, the report says so — in those words. A measurement instrument that knows its limits is worth more than one that admits none.
