Frequently Asked Questions

• What's the difference between translation and linguistic validation?

  Translation converts the words. Linguistic validation confirms the translated instrument measures the same concept, the same way, as the original — through cognitive debriefing with patients from the target population, not just a linguistic review.

• Which instrument types does Geo Language Services validate?

  PROs, ClinROs, ObsROs, and ePRO instruments, across paper and electronic formats.

• Does Geo Language Services follow ISPOR guidance?

  Yes. Our process follows ISPOR’s principles for translation and cultural adaptation, along with FDA and EMA regulatory guidance, so instruments are ready for submission.

• How long does linguistic validation take?

  It depends on the number of languages, instrument length, and patient population, but we scope timelines upfront so they fit your trial’s milestones. Get in touch and we can give you a realistic estimate.

• Who carries out the cognitive debriefing?

  In-country clinicians and native-speaking patients from the target population, working directly with our team.

• How is Geo Language Services different from large language service providers?

  Many linguistic validation providers manage projects through subcontracted networks or partner agencies. We work directly with the in-country linguists and clinicians on your project, no intermediary layer, so you know exactly who’s handling your instrument and can go straight to them with questions.

• Is a smaller, specialist provider as capable as a large LSP for multi-country trials?

  Yes — scale isn’t the same as capability. What matters for linguistic validation is direct oversight of every language pair and a consistent, audit-ready process, not the size of a subcontracted network. We manage multi-country projects with the same rigour whether it’s 6 languages or 60.

• Do you offer AI-assisted translation for linguistic validation?

  Linguistic validation depends on trained human linguists and cognitive debriefing with real patients — this isn’t a process AI can validate. Where relevant, we use technology to support project management and consistency, but the validation itself is always human-led.

• How does Geo Language Services align with C-Path eCOA Consortium standards?

  We align our eCOA linguistic validation process with the Critical Path Institute’s eCOA Consortium best practices, alongside ISPOR and FDA/EMA guidance — giving sponsors confidence the process holds up to regulatory scrutiny.

• How does Geo Language Services protect the data in our clinical documents?

  We hold Cyber Essentials certification alongside ISO 9001 and ISO 17100, so data security is built into how we handle sensitive clinical content, not bolted on afterwards.
