Validated-instrument-first study platform

Measurement you can defend.

ValidatedScale runs your validated instruments as rigorous studies. The protocol locks at launch, the field is monitored against a k-anonymity threshold, and the evidence exports arrive ready for analysis, with a codebook your statistician won't have to fix.

EU-hosted

Data is stored and processed in the EU. No transfer clauses to negotiate.

GDPR-native

Purpose, retention, and lawful basis are declared in the protocol, not in a PDF afterthought.

k-anonymity

Every report enforces a minimum group size. Below threshold, values are suppressed and say so.

Consent records

Versioned consent text and timestamped agreement, ready for your IRB or ethics board.

A study protocol in ValidatedScale: numbered chapters for design, instrument, scoring and policies, with the launch check in the margin
The respondent's consent sheet on a phone: study title, plain-language consent, participant code, and a Begin button

The protocol a researcher writes, and the sheet a respondent sees. Synthetic data.

Works with what you already use
Microsoft Entra ID

Your people sign in with their workplace account. No new passwords to manage.

Microsoft 365 directory

Import people and groups from your organization's directory, with admin consent.

Email invitations

Invitations and reminders from a verified sender domain, with delivery tracking.

CSV import

Bring a cohort from any spreadsheet. Preview first, import when the rows are clean.

SPSS · R · Stata

Exports ship with a codebook that documents every variable, so any stats tool reads them.

Your questionnaire

Any instrument you hold the rights to imports as a first-class citizen.

01Protocol

Declared once. Locked at launch.

A study begins as a document: the instrument you hold the rights to, the identity mode, the consent text, the scoring rules. When you launch, the protocol locks. What you report later is exactly what you declared.

Anonymous longitudinal linking uses self-generated participant codes, so waves connect without anyone holding a name.

Watch coverage, not people.

Share open links or send email invitations. The console shows what a defensible dataset needs: response counts, unit coverage against the k threshold, and nothing that identifies an individual.

03Evidence

Results your statistician can cite.

Scores are computed by the locked scoring rules and versioned. Re-open a study in two years and you get the same numbers. Waves compare side by side, linked by participant codes no one can reverse.

Exports arrive ready for analysis: clean CSV, labels SPSS understands, and a codebook that documents every variable, recode, and suppression.

Who runs studies here
Academic researchers
Occupational health · ergonomics · psychology

Anonymous longitudinal linking via self-generated codes, consent records your IRB will accept, and exports that go straight into analysis. EU hosting means no data-processing agreement odyssey.

OSH consultants
Psychosocial risk assessment · EU

White-label workspaces per client, legally mandated assessments run to protocol, and reports with the suppression rules written in, ready for compliance review and defensible in front of any works council.

Wellbeing officers
Hospitals · HR · continuous monitoring

Monitoring wave over wave, on dashboards where the protection is structural: nobody, including you, can re-identify an individual from a report.

And anywhere questionnaires carry weight
Universities & student affairs

Student wellbeing pulses, course evaluations, PhD programme monitoring. The anonymity is structural, so students actually answer.

HR & people teams

Engagement and workload tracking employees can trust: nobody, including you, can drill a dashboard down to one person.

Healthcare quality teams

Patient-experience and staff safety-climate surveys with consent records and retention rules an auditor will accept.

Public sector

Workforce stress monitoring for police, emergency services and schools, with governance that survives procurement. EU-hosted.

Consultancies & agencies

Run client studies in white-label workspaces; deliver defensible reports instead of spreadsheets.

Any longitudinal study

If you measure the same people twice and need to link answers without knowing names, this is the instrument for it.

Bring any questionnaire you have the right to use. The platform runs it with the same rigor.

The respondent's side

Consent first. Five quiet minutes.

Respondents see one calm sheet: the study in plain words, consent before a single item, and a progress rail that tells the truth. No accounts, no app, no dark patterns to inflate completion.

In anonymous studies they build their own participant code from stable personal facts. It links their waves without ever identifying them.

Consent · v3
Nurse workload, wave 3

Your answers are anonymous. Results are only reported for groups of 5 or more. You can stop at any time; partial answers are discarded.

Security posture, in plain words

No badges. Mechanisms.

EU Data residency

Stored and processed in the EU, full stop.

RLS Tenant isolation

Row-level security in the database, failing closed. One workspace can never read another.

k ≥ 5 Anonymity floor

The reporting threshold can be raised, never lowered. It is a constraint in the engine, not a setting.

v1 · v2 Consent evidence

Every consent text is versioned; every agreement is timestamped against its exact version.

2y → Retention, automated

Each study declares how long data lives and what happens then. Anonymization is the default.

log Audit trail

Who did what and when, recorded across setup, launch, collection and export.

Art. 17 Right to erasure

A built-in withdrawal workflow: requests are tracked, approved and executed, not emailed around.

DPA Paperwork

A signed data-processing agreement and a methods description for your ethics board, on request.

Formal certifications are on our roadmap. The mechanisms above are in the product today, and we would rather show you how they work than show you a logo.
