Clinical Trial Informed Consent and Recruitment Materials Translation — Pashto and Dari

Ariana Nexus translates informed consent forms, assent forms and participant recruitment materials into Pashto and Dari for sponsors, CROs, research sites and IRBs. Health-trained Afghan linguists translate, a second linguist reviews, an independent translator back-translates, and every study receives a certificate of translation accuracy for IRB submission.

Anatomy of a Pashto or Dari consent form: what we do in every section

Specimen layout. Title lines in Pashto and Dari read right to left.

  1. Key information

    Written first and plainest, as the Common Rule requires, in sentences most readers can follow.
  2. Why the study is being done

    Research terms such as “investigational” explained in everyday Pashto or Dari.
  3. What will happen

    Visits and procedures kept in the same order and numbering as your English form.
  4. Risks and discomforts

    Probability words fixed in the study glossary, so “rare” and “common” mean the same thing everywhere.
  5. Possible benefits

    No overstated promises; benefit wording checked against the source by the back translator.
  6. Your choices

    Voluntary participation and the right to stop, stated simply and without pressure.
  7. Privacy and your information

    Who sees information, what is recorded and what leaves the study, in plain words.
  8. Payment and costs

    Amounts, schedules and reimbursements rendered exactly, with the numerals your participants read.
  9. Contacts and questions

    Names, phone numbers and IRB contacts checked character by character.
  10. Signatures

    Signature, date, witness and interpreter lines placed as your IRB approves, including for the short form route.

Why Pashto and Dari consent translations fail — at the IRB and with participants

A consent form can pass a spell-check and still fail the person who signs it. These are the four failures we see most often in Afghan-language research materials.

  • Dari delivered as Iranian Farsi

    Dari and Iranian Persian share a script, not a clinical vocabulary. An Afghan reader who meets Tehran words for doctor, medicine and participant may sign a form that feels foreign and is only partly understood.
  • A written form for participants who read little

    UNESCO estimates adult literacy in Afghanistan at 37 percent, and about 23 percent among women. For many participants the written consent must travel with a spoken version: audio, video or a discussion with a qualified interpreter.
  • Risk wording that shifts meaning

    Phrases such as “may occur,” “unlikely” and “cannot be ruled out” carry scientific weight. Rendered loosely, a rare side effect can sound certain and a common one remote. We fix probability wording before translation starts.
  • Questions of trust left unanswered

    Many Afghan families arrived after war and displacement. A consent form has to say plainly who sees their information, what is recorded and how to stop, in words that inform without alarming.

Pashto and Dari, matched to where your participants are from

Pashto and Dari are Afghanistan's two principal languages, and many Afghans speak one at home and read the other. We recommend one, the other or both after looking at your participants' regions, ages and schooling.

پښتو

Pashto

Also written Pushto or Pakhto
Written in the Afghan standard. For audio, video and consent discussions we match the spoken variety: Kandahari, Central, Eastern and Khosti, and Peshawari for participants educated in Pakistan, where spelling conventions differ.
دری

Dari

Afghan Persian
Afghanistan's Dari, written for Afghan readers and never substituted with Iranian Farsi. Spoken varieties matched: Kabuli, Herati and Hazaragi, a variety of Dari with its own vocabulary and accent.

Examples only. Each study's glossary is set with your team before translation begins.

Enrolling speakers of Uzbeki, Turkmeni, Balochi or another Afghan language? We scope them with the same method. Several Afghan languages have no settled written standard; for those, consent moves by recorded audio and interpreter-supported discussion under your IRB-approved process.

Matched by dialect, gender and health education — not just bilingual

A bilingual speaker can read both texts. A matched linguist knows how a family from Kandahar or Herat will read yours.

Dialect and region

Written text uses the standard your participants learned in school. Voices for audio, video and consent discussions match the spoken variety of the community you are enrolling.

Gender, where it matters

Pashto marks gender in verbs and adjectives, so materials for women are written in the correct forms. For women's health and sensitive studies, women linguists and interpreters are assigned on request.

Health-sciences education

Every linguist holds a college degree. Consent work goes to linguists trained close to medicine or public health, so “randomized,” “placebo” and “biospecimen” are explained rather than transliterated.

Research literacy

Our reviewers work from the protocol, respect locked sponsor and institutional language, and keep wording consistent across versions, sites and amendments.

Diaspora experience

Our linguists come from the Afghan diaspora. They know how war, displacement and past encounters with authorities shape the questions a participant asks before signing.

Reading level

English readability scores do not measure Pashto or Dari. We write plain language and confirm it with native readers of the target variety instead.

How we translate an informed consent form into Pashto or Dari

  1. Scope the source

    We read the IRB-approved English, flag locked and ambiguous language, and confirm languages, varieties, reading level and formats.
  2. Build the study glossary

    Protocol terms, drug names and probability wording are fixed in Pashto and Dari before translation starts, then reused in every document and amendment.
  3. Translate for meaning

    A health-trained native linguist translates into plain, natural Pashto or Dari.
  4. Review independently

    A second linguist checks accuracy, completeness, terminology and tone against the English source.
  5. Back-translate blind

    A translator who has not seen the English source renders the Pashto or Dari back into English.
  6. Reconcile and record

    Every difference is resolved and logged, so your team can see each decision in the reconciliation report.
  7. Check with native readers

    Readers of the target variety confirm the text is clear. Structured comprehension testing (cognitive debriefing) is available for higher-risk studies.
  8. Lay out, certify and version

    Right-to-left layout in your template, a certificate of translation accuracy, and version numbers matched to your English source.

The rules that call for translated consent

Instrument
What it requires
What it means for your study
What it requires
Consent information in language the participant understands, documented on an IRB-approved written form or through the short form route.
What it means for your study
FDA-regulated studies need an accurate Pashto or Dari consent whenever those participants are expected.
What it requires
The same standard under the Common Rule, with key information presented first and a short form route that needs a witness and an IRB-approved summary.
What it means for your study
A short form covers unexpected enrollment; it does not replace a translated consent.
What it requires
Health and clinical research by recipients of HHS funding is a covered health program. Written translation needs a qualified translator, and machine translation of critical text needs one to review it.
What it means for your study
Academic medical centers and funded research sites need qualified human translators for Afghan participants.
What it requires
A translated consent when non-English speakers are expected, checked for accuracy. After a short-form enrollment, the long form is translated promptly and given to the participant.
What it means for your study
A certificate of translation accuracy documents the check; a priority track covers short-form follow-ups.
What it requires
Participant-centered consent, including technology-enabled methods such as eConsent. FDA issued it as final guidance in September 2025.
What it means for your study
eConsent screens, audio and video in Pashto and Dari must carry the same approved content as the written form.
What it requires
Information a layperson can understand. In the United Kingdom since April 28, 2026, sponsors must also offer participants a summary of results they can understand.
What it means for your study
Studies in Europe and the United Kingdom need Pashto and Dari consent and results summaries to the same standard.

This summary helps you plan. Your IRB decides what your study requires.

Why sponsors, CROs and research sites choose Ariana Nexus

Where no certification exists, we set the standard.

No U.S. certification exam tests translation from English into Pashto or Dari. So we built the standard ourselves: degree-holding Afghan linguists, assessed in the exact variety they translate, trained in ethics and HIPAA, with a second linguist on every document. We extend that training to Afghan diaspora interpreters and students beyond our own team.

A consulting firm, not a vendor

We plan your consent approach — written, audio or interpreter-supported — before a word is translated, and we stay with the study through every amendment.

Led by scholars of leading universities

The people who lead our work studied at Cornell, Brown, West Chester University and the University of British Columbia, in public health, psychology and computer science.

Afghan-led and community-rooted

Our partners lived in Kabul and Herat. We know the questions Afghan families ask before they sign, and how to answer them in their own words.

One firm, one point of accountability

Translation, review, back translation, audio and interpretation are produced by our own people. No subcontractors and no hand-offs you cannot see.

Security built for research data

NDAs before files move, BAAs when health information is involved, access-controlled handling, and nothing routed through channels controlled by the de facto authorities in Afghanistan.

People write consent. Technology checks it.

Qualified linguists write and review every participant-facing sentence. Our tools check terminology and completeness; they never write consent language.

The team behind your Pashto and Dari consent translations

Your study is guided by a team trained at Cornell, Brown, West Chester University and the University of British Columbia, and delivered by a bench of degree-holding Afghan linguists.

Questions research teams ask about Pashto and Dari consent translation

Do IRBs require a certified translation of a consent form into Pashto or Dari?

Federal rules require consent information in language the participant understands, and Section 1557 requires a qualified translator when a recipient of HHS funding runs the research. None of them names a certification. Most IRBs ask for a certificate or attestation of accuracy, and every Ariana Nexus consent translation comes with a signed certificate of translation accuracy.

Is Dari the same as Farsi for a consent form?

No. Dari and Iranian Persian share a script and most grammar, but everyday clinical words differ. Afghan readers expect داکتر for doctor and دوا for medicine, not the Iranian پزشک and دارو. A Farsi consent form can read as foreign to an Afghan participant, so we translate into Afghanistan's Dari.

Should our study translate into Pashto, Dari or both?

Often both. Pashto and Dari are Afghanistan's two principal languages, and many Afghans speak one at home and read the other. We look at where your participants come from, their ages and their schooling, then recommend the languages and spoken varieties to use.

Does our IRB need a back translation?

FDA and Common Rule regulations do not require one, but many sponsors and IRBs expect it for consent forms. We include an independent, blind back translation and a reconciliation report with every informed consent translation, so reviewers can compare meaning line by line.

Can we use a short form consent for Pashto or Dari speakers?

The short form route in 45 CFR 46.117(b)(2) and 21 CFR 50.27(b)(2) is for unexpected enrollment: an oral presentation, a witness and an IRB-approved written summary. In FDA-regulated studies, FDA's 2023 guidance says the full consent should then be translated promptly, approved by the IRB and given to the participant as soon as possible. We translate short forms in advance and move the full consent on a priority track.

How do you support participants who cannot read Pashto or Dari?

Many Afghan adults, especially women, had little chance to attend school. We pair the written consent with audio or video in the participant's variety, plain scripts and teach-back questions for the consent discussion, and qualified Pashto and Dari medical interpreters when your IRB-approved process calls for one.

Can Afghan women participants work with women linguists and interpreters?

Yes. On request, women linguists review sensitive content, record voice-overs and run comprehension checks for women's health, reproductive and mental-health studies, and women interpreters join consent discussions. Pashto marks gender in its grammar, so materials addressed to women are written in the correct forms.

How long does it take to translate an informed consent form into Pashto or Dari?

It depends on length, the number of documents and varieties, and whether back translation and audio are included. We confirm a delivery date in writing with your quote, plan around your IRB submission, and offer a priority track for short-form follow-ups and urgent amendments.

How much does informed consent translation cost?

We quote a fixed price per study after reviewing word count, languages and varieties, back translation, layout, audio or video, and deadlines. Sponsors and CROs with several studies or frequent amendments can use program or framework pricing.

Do you use machine translation or AI for consent forms?

Qualified people translate and review every participant-facing sentence. We use technology to keep terminology consistent and to confirm nothing was missed, never to write consent language. Where Section 1557 applies, machine translation of critical health information must be reviewed by a qualified human translator, and a consent form is critical information.

How do you keep study documents and participant data secure?

We sign an NDA before files move and a business associate agreement whenever protected health information is involved. Files are handled only by Ariana Nexus's own team in access-controlled systems and are never routed through channels controlled by the de facto authorities in Afghanistan.

Do you support trauma-informed consent for studies with Afghan refugees and war-affected participants?

Yes. For research on PTSD, moral injury (sometimes searched as moral trauma), depression and other effects of the Afghan war and displacement, we write consent language that is calm and specific about recording, data sharing and the right to stop, and that avoids words carrying stigma in Afghan communities.

Is there a U.S. certification for Pashto or Dari translators?

No U.S. certification exam tests translation from English into Pashto or Dari. We built our own standard: every linguist holds a college degree, is assessed in the variety they translate, completes ethics and annual HIPAA training, and has each document reviewed by a second linguist.
