Questionnaire translation: a significant challenge

The success of an international survey is closely linked to the reliability of the data collected and the comparability of results across different countries.

Without comparable results, you will be unable to use your data, and all of your investment - in terms of time and financial resources - may end up being wasted.

To avoid these pitfalls, it is vital to produce equivalent translations in all countries.

In short, questionnaire translation is a tricky undertaking, because all respondents around the globe must interpret the same question in the same way - otherwise the data collected will be skewed.

Why should I have my surveys translated by a professional translation agency?

In order for an international survey to be usable, it is important to ensure that:

  • Equivalent translations are delivered in all relevant countries
  • Possible ambiguity in translated versions is eliminated
  • Skewed results, due to a misinterpretation of questions by respondents, are avoided
  • Reliable and comparable data is collected.

Translating a questionnaire is something of a balancing act, in that the linguist must produce a translation that reads naturally, while remaining extremely disciplined about maintaining equivalence between the source and target versions. 

These aims can only be achieved by entrusting your translations to an agency that is specialised in the translation of surveys and market research, one that is acutely aware of the challenges specific to this sector.

What are the risks of a poorly translated international survey?

A multilingual survey that is not translated with great care and professionalism is, simply put, unusable, because its results may be heavily skewed due to the lack of equivalence between the translated versions.

In neglecting the translation phase of your survey, you therefore run the risk of not reaping the benefits of all of the investment (be it in terms of time, money, staff engagement, use of tools, etc.) made to bring it about in the first place.

A single misinterpreted question in two or three countries can completely invalidate the results of a survey. In these conditions, it is impossible to draw any general conclusions and to compare data from one country to another. Even the slightest approximation is enough to distort all of the survey's conclusions.

How much does the translation of a questionnaire or survey cost?

In addition, in our constant pursuit of excellence, we have instigated a specific quality assurance process for each of the following five areas:

  • Recruitment, selection and ongoing evaluation of linguists:
    Innovative recruitment process ("Smart Recruit"), careful selection of candidates, and continuous assessment of the quality of their work.
  • Quality assurance:
    Checking of the source text, systematic review by a second translator, in-house quality control.

    Use of a TMS (Translation Management System) and a CAT tool (Computer-Assisted Translation).

    Single project manager, understanding of client's requests and wishes. 
  • Confidentiality:
    Confidentiality agreement signed by all our partners.

Our high-quality services and expertise have resulted in us working with some major players in the opinion poll and market research sector, such as Kantar, BVA and Gallup International.

What are the steps involved in the translation of a survey or questionnaire?

To ensure the equivalence of translations, we adhere to a proven methodology, which may vary according to the project, objectives and client budget. We systematically carry out a check of the source version and a review of the translation in all cases.

Translation with double review

The translation is executed by an experienced native-tongue translator, and is then reviewed twice by different linguists:

  • The first review involves a comparison between the source and target versions to ensure equivalence (with the insertion of corrections where necessary).
  • The purpose of the second review is to pick up on any remaining typos or minor errors.

Translation with double review and back-translation

After the double review, all translations are then back-translated into the source language. This additional step enables us to pinpoint and rectify any shifts in meaning or mistranslations.

TRAPD approach

This method consists of five phases:

  • T — Translation
    Two translations are produced independently by different translators.
  • R — Review
    The translators and reviewers compare the translations produced in the previous step.
  • A — Adjudication
    The two translations are reconciled: the best translation is selected for each survey question, after which a harmonised target version is generated.
  • P — Pretest
    National versions are tested in a pilot study (small-scale preliminary study).
  • D — Documentation
    Documentation of the entire process.
