Can a relative always interpret?

Do not assume so without considering confidentiality, impartiality, competence and applicable study rules. Arrange suitable support with the investigator.

Can an interpreter explain the participation decision?

They can help communicate the person’s decision clearly, but deciding for them or encouraging enrollment is outside the supporting role.

Defining the Interpreter Role in Study Consent

Language support involves more than translating sentences on a form. A study candidate needs to ask questions, understand the answers and express a decision in their own words. The interpreter’s role can be planned around that two-way communication.

Define the workflow

The site reviews the language version, interpreter competence and confidentiality arrangements before the discussion. An interpreter should not act as an advocate for participation. Rather than replacing approved documents with informal oral translation, staff should examine the study process and applicable local requirements.

Worked example

For example, a relative begins shortening technical explanations while interpreting. Staff recognize that important details are being lost and arrange suitable language support. The investigator continues addressing the candidate directly, preserving eye contact and the individual’s decision space even when speech passes through an interpreter.

Practical checks

Identify the person’s language, dialect and preferred communication method before the appointment.
Discuss limits on adding explanations, summarizing information and offering personal advice.
Plan to check understanding of important concepts through the candidate’s own explanation.

Decision and boundaries

The process works when the candidate can communicate personal questions as well as receive answers. Having an interpreter does not automatically satisfy document approval or legal representation requirements. Significant communication problems and the measures taken should remain traceable in appropriate study records.
