Cross-cultural adaptation,
done right.

Equivalence guides research teams through every stage of translating and adapting measurement instruments — with enforced stage gates, blinded peer review, and publication-ready outputs built in.

How it works

A structured, auditable workflow from source instrument to locked adapted version — following established cross-cultural adaptation guidelines.

  1. 1

    Set up your project

    Choose your source and target languages, select a framework (Beaton/ISPOR, TRAPD, ITC, or Dual-panel), and invite your translation team by email.

  2. 2

    Enter source items

    Upload or type the items from the original instrument. Flag translatability concerns, mark culturally adapted items, and add rationale for any introduced items.

  3. 3

    Forward translation (blinded)

    Each translator works independently. Equivalence enforces blinding at the API level — no translator can see another's version until everyone has submitted.

  4. 4

    Reconciliation

    The project leader reviews T1 and T2 side-by-side with word-level diff highlighting, selects or synthesizes a reconciled version, and documents the decision rationale.

  5. 5

    Back-translation & expert review

    A back-translator renders the reconciled text back to the source language. An expert committee rates each item on the 4-point CVI scale (Lynn, 1986).

  6. 6

    Cognitive debriefing

    Log participant feedback with anonymized codes, flag comprehension issues by type, and track resolution status per item.

  7. 7

    Publication-ready outputs

    Export the CVI summary table, auto-generated methods paragraph, PRISMA-style flow figure, and a signed Equivalence Audit Certificate with SHA-256 version hash.

Process fidelity

Beaton/ISPOR, TRAPD, Dual-panel, and ITC workflows with enforced stage gates and mandatory rationale fields.

Blinding integrity

Translators cannot see each other's work until all slots are submitted. Enforced at the API and database level — not just the UI.

Publication-ready outputs

Auto-generated CVI tables, methods paragraphs, flow figures, and signed audit certificates with SHA-256 version hashes.
