I support organisations in the linguistic and cultural adaptation of questionnaires and other patient-facing materials used in clinical research.

My work sits at the intersection of clinical practice and specialised medical language expertise. As a former oncology nurse working in clinical research, I spent many years supporting patients participating in clinical trials. I understand how questionnaires are experienced in real clinical settings — where patients hesitate, what feels unclear or overly technical, and what helps create reassurance and clarity.

I combine this clinical perspective with specialised training in linguistic validation and extensive experience in medical translation and quality review.

This results in an approach where conceptual accuracy, cultural appropriateness and practical usability come together. Questionnaires and other patient-facing materials must not only be methodologically sound, but also clear and credible for the people completing them. European regulatory frameworks emphasise that information intended for end users must be clear and accessible

Expertise

Support across different phases of linguistic validation projects, including:

  • Forward and back translation (FT/BT)
  • Reconciliation
  • Back translation review
  • Cognitive debriefing (recruitment, interviews, analysis and reporting)
  • In-depth review of patient-facing texts
  • Consistency and terminology checks
  • LQA / quality review
  • Cross-language harmonisation

Depending on the project, I work in an operational or advisory role, or as a subject-matter specialist within multidisciplinary teams.

Who I work with

I collaborate with, among others:

  • CROs
  • Pharmaceutical and medtech companies
  • Language service providers (LSPs)
  • Sponsors and research organisations

Within these contexts, I work as a specialist at the intersection of language, clinical research and the patient perspective.

Collaboration

I work on a project basis, as a consultant within ongoing programmes, or as an additional specialist within an existing team. The form of collaboration depends on the phase of the project and the specific needs of the study.

If you would like to discuss the linguistic and cultural adaptation of questionnaires or other patient-facing materials in clinical research, I would be happy to help.
