Pharmaceutical and life sciences research depends on clear communication. Researchers need accurate information from participants, clinical teams must explain complex study procedures, and sponsors need documentation that supports consistent research practices.
When participants speak different languages, communication requires additional planning.
Language access in pharmaceutical and life sciences research helps people understand study information, communicate with research teams, and participate in research activities in a language they understand. It includes professional interpretation, document translation, multilingual participant materials, and procedures for addressing language needs throughout a study.
For pharmaceutical companies, clinical research organizations (CROs), universities, medical device manufacturers, and research institutions, language access should be considered early in the research process rather than treated as a last-minute administrative task.
What Is Language Access in Pharmaceutical and Life Sciences Research?
Language access refers to the practical measures used to help people communicate and understand information when they do not share the same language.
In pharmaceutical and life sciences research, these measures can include:
- Translating informed consent forms and participant information sheets.
- Interpreting conversations between research staff and participants.
- Translating recruitment materials, questionnaires, and study instructions.
- Supporting multilingual communication during clinical trial visits.
- Translating relevant safety information and participant communications.
- Reviewing scientific and regulatory documents intended for international audiences.
The appropriate services depend on the research design, participant population, study procedures, and applicable requirements.
For example, a U.S. clinical trial recruiting Spanish-speaking participants may need professionally translated consent materials and qualified interpreters during consent discussions and follow-up visits. A pharmaceutical company preparing regulatory documentation for multiple markets may need a different combination of scientific translation, terminology management, and quality review.
These activities serve different purposes, but they share one requirement: the meaning of the original information must be preserved.
Why Language Access Matters Across the Research Lifecycle
Language access affects more than the initial decision to participate in a study. Participants may need to understand instructions, describe symptoms, ask questions, and report changes throughout their involvement.
The National Institutes of Health has specifically highlighted language access as a consideration when planning NIH-supported clinical research, including participant communication, budgeting, and inclusion. NIH’s guidance and resources on research inclusion provide a useful starting point for research teams.
1. Recruitment and Participant Outreach
Recruitment materials help potential participants determine whether a study may be appropriate for them.
When these materials are available only in English, people who prefer another language may struggle to understand the study’s purpose, eligibility criteria, time commitments, or participation requirements.
Translated recruitment materials can help researchers explain the study more clearly to the intended population. Depending on the project, these materials may include advertisements, introductory letters, screening questionnaires, website content, and participant information sheets.
Translation alone does not guarantee that a study will recruit a representative population. Researchers must also consider where recruitment takes place, how potential participants are reached, and whether the study’s eligibility criteria are appropriate for its scientific objectives.
Planning language access early allows sponsors and research teams to identify likely language needs, arrange qualified resources, and account for the associated costs.
2. Informed Consent and Participant Understanding
Informed consent is one of the most important areas of language access in clinical research.
Before joining a study, prospective participants need to understand relevant information about the research, including its purpose, procedures, reasonably foreseeable risks, potential benefits, and alternatives where applicable.
Under 21 CFR § 50.20, information provided during informed consent for research covered by the FDA regulations must be in language understandable to the participant or their legally authorized representative. FDA guidance also addresses the need for translated consent documents when a study population includes people who do not speak English and consent discussions are expected to occur in another language.
The FDA explains these requirements in its Informed Consent Guidance for IRBs, Clinical Investigators, and Sponsors.
A translated form is only one part of the process. Participants may also need an interpreter to ask questions, discuss their concerns, and understand explanations from the research team.
Consider a participant who speaks limited English and is invited to join a study evaluating an investigational treatment. The consent materials explain possible risks, the study schedule, and procedures for reporting adverse events.
A professionally translated consent form can provide a written reference. A qualified interpreter can support the conversation in which the participant asks questions and the research team checks their understanding.
The goal is not simply to obtain a signature. It is to support an informed decision.
3. Study Visits and Ongoing Communication
Clinical research can involve repeated visits, follow-up calls, remote consultations, questionnaires, and discussions about study procedures.
Participants may need to explain how they feel, describe changes in symptoms, ask about instructions, or discuss difficulties following a study schedule.
Professional interpretation can help research staff and participants communicate during these interactions.
For example, a participant might report a new symptom but struggle to describe when it began or how severe it feels. A qualified interpreter can convey the participant’s account so the research team can ask appropriate follow-up questions and document the information.
The interpreter does not assess the symptom or make clinical decisions. Those responsibilities remain with the qualified research or healthcare professionals.
Language access should therefore be planned for the full period of participation, not just the recruitment and consent stages.
4. Safety Reporting and Adverse Event Communication
Clear communication is particularly important when participants report symptoms, side effects, or other concerns during a study.
A participant may need to explain what happened, when it started, whether it has changed, and whether they have sought medical attention. Language barriers can make these conversations more difficult.
Professional interpretation can support communication between participants and research staff, helping the team obtain and document the participant’s account.
Translation may also be needed for written safety instructions, participant diaries, follow-up questionnaires, or other study materials.
These services must fit within the study’s established safety-reporting procedures. Interpreters should convey information accurately without independently deciding whether an event is medically significant, whether it qualifies as an adverse event, or what action should follow.
Sponsors and investigators remain responsible for the applicable safety assessment, documentation, and reporting obligations.
5. Research Documentation and Scientific Materials
Language access extends beyond direct communication with participants.
Pharmaceutical companies, CROs, academic researchers, and medical device manufacturers may work with scientific and regulatory documentation intended for different audiences or markets.
Depending on the project, translation may be required for:
- Clinical study protocols and related materials.
- Investigator-facing documentation.
- Participant diaries and questionnaires.
- Study instructions and educational materials.
- Medical device clinical investigation materials.
- Research summaries and participant-facing results.
- Regulatory submissions and supporting documentation.
Not every document needs to be translated into every language. The requirements depend on the intended audience, study design, applicable regulations, and the markets in which the materials will be used.
Scientific translation requires particular care. A seemingly small change in terminology, dosage units, eligibility criteria, or descriptions of study procedures may affect how a document is understood.
A controlled translation workflow, with appropriate subject-matter review and version management, helps organizations maintain consistency across languages.
Translation and Interpretation: Which Service Does Research Need?
Although the terms are sometimes used interchangeably, translation and interpretation solve different problems.
| Service | Primary purpose | Research example |
|---|---|---|
| Translation | Converts written content between languages | Translating an informed consent form |
| Interpretation | Conveys spoken communication between languages | Interpreting a consent discussion or follow-up visit |
| Linguistic review | Checks language accuracy, terminology, and readability | Reviewing translated participant questionnaires |
| Terminology management | Maintains consistent use of approved terminology | Managing clinical and scientific terms across study documents |
| Transcription | Converts recorded speech into written text | Preparing a transcript of a recorded research interview |
A clinical trial may require several services at different stages. A translated consent form may be needed before enrolment, while interpretation may be required during consent and follow-up visits.
A multilingual research project may also require translation review, terminology management, and quality checks across multiple documents.
The correct approach is to define the purpose of each deliverable before selecting a provider.
Language Access in Pharmaceutical and Medical Device Development
Language requirements can vary across the life sciences sector.
Pharmaceutical Research
Drug development involves scientific documentation, clinical studies, participant communication, and interactions with regulatory authorities.
Language services may support recruitment, consent, study visits, safety communications, and the translation of scientific or regulatory documents.
Because pharmaceutical terminology can be highly specialized, providers should demonstrate the linguistic and subject-matter competence appropriate to the assignment.
Medical Device Research
Medical device clinical investigations may involve technical procedures, device-specific instructions, participant questionnaires, and consent materials.
Translated documents must preserve the meaning of technical descriptions and study procedures. Where participants interact with a device or follow specific instructions, the language used must be appropriate for the intended audience.
FDA’s guidance on informed consent for clinical investigations provides relevant information about informed consent in device research.
Academic and Institutional Research
Universities, teaching hospitals, and research institutions may conduct studies involving participants from different linguistic backgrounds.
Language access should be considered during study design, recruitment planning, budgeting, and development of participant-facing materials.
Researchers conducting NIH-supported studies can consult NIH resources on language access and participant inclusion when developing their research plans.
U.S. Regulatory and Ethical Considerations
Research teams should distinguish between regulatory requirements, institutional policies, ethical responsibilities, and recommended practices.
FDA Informed Consent Requirements
For research covered by FDA’s human-subject protection regulations, 21 CFR § 50.20 requires the information given to participants or their legally authorized representatives to be in language they can understand.
FDA’s Institutional Review Boards frequently asked questions also address translated consent forms. When a study population includes people who do not speak English and consent interviews are expected to take place in another language, the IRB should ensure that an accurate translated consent form is prepared. The FDA also explains that routine ad hoc translation of the consent document should not be substituted for a written translation. See the FDA’s IRB FAQ.
Research teams should work with the responsible IRB and study leadership to determine the appropriate documentation and consent procedures for their specific study.
NIH-Supported Research
NIH has published resources specifically addressing language access for participants in NIH-supported clinical research. These resources discuss planning, participant communication, policies, and potential budget considerations.
NIH’s inclusion policies also address the inclusion of women and members of racial and ethnic minority groups in applicable NIH-funded clinical research. These policies concern research inclusion and should not be misrepresented as a universal requirement to provide every participant with every document in every language.
Researchers should review the current NIH requirements applicable to their award and study. See NIH’s inclusion policies for human-subject research.
Institutional Review Boards and Research Ethics
IRBs review research involving human participants within their applicable oversight responsibilities. Their review may address consent materials, recruitment practices, and procedures for conducting the consent process.
Language access plans should be coordinated with the responsible IRB and research institution rather than implemented independently of the study’s approved procedures.
A Practical Compliance Principle
There is no single federal rule that requires every pharmaceutical or life sciences organization to translate every research document into every language.
The applicable requirements depend on the type of research, the relevant regulations, the participant population, institutional oversight, funding conditions, and other circumstances.
Organizations should seek qualified regulatory or legal advice when determining their obligations. This article provides general information, not legal advice.
How to Build a Language-Access Strategy for Research and Development
A practical strategy begins before the first participant is recruited.
Step 1: Identify Language Needs Early
Review the intended participant population, recruitment locations, planned study procedures, and likely communication needs.
Identify which languages may be needed for recruitment, consent, study visits, questionnaires, and follow-up communications.
Step 2: Map the Required Materials and Interactions
Create an inventory of documents that may require translation and interactions that may require interpretation.
Assign responsibility for determining which versions are approved, which languages are required, and how updates will be handled.
Step 3: Establish a Budget and Timeline
Translation, review, interpretation, and document revision require time and resources.
Include language services in study planning and account for the possibility that participant needs may change as recruitment progresses.
NIH’s resource on considering language access in NIH-supported clinical research specifically discusses planning and budget considerations.
Step 4: Define Quality-Control Procedures
Establish procedures for translation review, terminology consistency, version control, and approval of participant-facing materials.
For interpreting, define how appointments are arranged, how interpreters receive relevant context, and how communication problems are escalated.
Step 5: Plan for the Entire Participant Journey
Consider language needs at every relevant stage, including initial contact, screening, informed consent, study visits, safety communications, and follow-up.
A plan that covers only consent may leave participants without appropriate support during later study interactions.
Step 6: Review and Improve the Process
Research teams should review whether language services are available when needed and whether participants can communicate effectively during study activities.
Feedback from study personnel and participants can help identify gaps, improve workflows, and inform future research planning.
How to Choose a Language-Services Provider for Life Sciences
Not every translation or interpretation provider has the same experience. Selecting a suitable partner requires an assessment of the actual work involved:
- Relevant subject-matter expertise: Look for experience appropriate to pharmaceutical research, clinical trials, medical devices, or the specific scientific field.
- Qualified interpreters: Ask how interpreters are assessed and whether they have experience with clinical research terminology and participant-facing interactions.
- Translation quality assurance: Understand how translations are reviewed, how terminology is managed, and how changes are incorporated into approved materials.
- Confidentiality and data handling: Review confidentiality commitments, information-security practices, and arrangements for handling sensitive research documents and participant information.
- Scalable language coverage: Determine whether the provider can support the required languages, locations, formats, and timelines.
- Clear project management: Confirm who coordinates requests, manages deadlines, maintains version control, and resolves quality concerns.
A provider should be able to explain its process clearly and demonstrate that its capabilities match the project’s requirements.
