Consent localization is a clinical communication task. A grammatically correct translation can still describe an impossible local visit, an unreachable contact or a payment arrangement that the site does not use.

Translate the participant experience

TİTCK ethics guidance and good clinical practice provide the local review context. Start from the controlled sponsor master and identify the information participants need about procedures, foreseeable risks, alternatives and their choices. Keep trial participation distinct from routine care when explaining the local pathway.

Use a meaning comparison table

We recommend a meaning comparison table with the master text, Turkish wording, rationale and medical reviewer decision. Give special attention to randomization, placebo, withdrawal, data use and sample handling. A back translation can reveal differences, but it does not demonstrate that a participant can understand the final wording.

Check the local pathway

  • Walk each described visit against the protocol and the site's actual service arrangements.
  • Verify investigator, emergency, complaint and participant inquiry contact information.
  • Reconcile expense reimbursement and insurance statements with the approved local plan.
  • Record plain-language review, unresolved questions and the submitted version history.

Resolve uncertainty before review

Test difficult passages by asking a reviewer unfamiliar with the protocol to explain them in their own words. This is an operational recommendation, not a substitute for ethics review or the investigator's consent discussion. Retain the resolution of material translation differences.

Frequently asked questions

Does back translation replace participant-oriented review?
No. It tests alignment with the master, while comprehension needs a separate assessment.
May the translator repair a protocol inconsistency?
Flag it for the responsible medical and regulatory reviewers; do not silently change the study's meaning.
