How to run multi-country qualitative research: a practical guide
Multi-country qualitative research can give businesses a richer understanding of how attitudes, behaviours and needs differ across markets. But adding countries to a project does not mean repeating the same study in different places. Recruitment approaches, incentive expectations, languages and cultural norms vary, while working patterns, time zones and public holidays affect the schedule. Each market needs careful planning to ensure the research remains locally relevant and comparable across countries.
The most successful studies combine consistency where it matters with flexibility where it is needed. Having delivered research across 65 countries and more than 600 multi-country projects, we have seen what helps international qualitative research run smoothly and where avoidable problems arise. Here are ten things to consider.
1. Assess feasibility market by market
An audience that is straightforward to recruit in one country may be much harder to reach in another. The same job title, consumer behaviour or product category can have different incidence rates across markets. A senior technology decision-maker might be readily accessible in one country but difficult to recruit elsewhere; healthcare systems, company structures and purchasing responsibilities can also vary considerably.
Assess feasibility market by market rather than applying one estimate across a region. If a country looks especially challenging, identify that early and adjust the recruitment approach, timeline or sample. Good feasibility work shows where pressure points are likely to arise before fieldwork begins.
2. Decide what needs to be consistent and what needs to be localised
International research needs enough consistency for meaningful comparisons, but identical procedures do not always produce comparable results. The research objective, core eligibility criteria and main discussion themes should usually remain consistent. Questions and answer options may need adapting to local circumstances.
For example, income and company turnover bands may need adjusting; education categories and job titles may differ; and relevant brands or products may vary by market. Even a term such as “senior decision-maker” may require local clarification. The aim is to recruit genuinely comparable people, rather than insist on an identical screener whose questions mean different things in different countries.
3. Build the recruitment strategy around each audience
There is no single recruitment source that suits every international project. Consumer research might draw on panels, databases, social recruitment or targeted free-find approaches. Specialist B2B studies may require professional networks, industry contacts and detailed validation, while healthcare audiences bring their own considerations.
For challenging profiles, establish where potential participants can be found, how difficult they will be to engage, what can be independently verified and what incentive is appropriate. Consider, too, what could make someone unsuitable despite their answers to the screener. The best route to a comparable participant may differ substantially between markets.
4. Don’t just tranlate the screener, localise it
A technically accurate translation can still sound unnatural, introduce ambiguity or fail to reflect how people describe themselves locally. In qualitative recruitment, small differences in wording can change who qualifies.
Questions about income, education, seniority, purchasing responsibility, ethnicity, brands and industry terminology often need local review. Recruiters or moderators in each market can identify unusual terms, missing answer options and questions that do not work in context. Allowing time for that review is easier than discovering a problem after unsuitable respondents have been recruited.
5. Apply consistent participant-quality checks
The methods used to validate participants may vary by audience and market, but the underlying quality standard should remain the same. Checks might include re-screening by telephone or video, open-ended questions that test knowledge, professional verification, and reviews for inconsistent responses, duplicate applications or previous research participation.
These checks matter particularly in highly incentivised studies. Fraudulent applicants and professional respondents can appear convincing on an initial screener. Alongside checking whether someone meets the stated criteria, the project team needs reasonable confidence that the person is genuinely who they say they are.
6. Make the right decision about language and moderation
Research in English can work well when participants regularly use it in the relevant part of their lives. Senior employees in multinational organisations, for example, may be comfortable discussing their work in English. The ease of coordinating a study in one language should not, however, decide the approach on its own.
People may express complex opinions and experiences more naturally in their first language. Requiring English can reduce the depth of responses and favour participants with particular educational or professional backgrounds. Choose the language according to the audience and research objectives. Where local-language moderation is needed, use moderators who understand the subject and cultural context and can probe naturally, rather than simply follow a translated guide.
7. Get incentives right in each market
Consider incentives country by country. The right amount depends on the audience, seniority, methodology, session length and commitment required, as well as local expectations. An amount that attracts participants in one market may be excessive or insufficient in another.
A 60-minute interview with a general consumer and one with a senior specialist are different recruitment tasks despite their identical length. Incentives should attract suitable people without becoming so disproportionate that they encourage unsuitable applicants to try to qualify. Local recruitment experience helps establish the right level.
8. Plan around time zones, holidays and local working patterns
A project team in London, a client in New York and participants in Asia can make scheduling difficult even before further markets are added. Public holidays and religious celebrations can also reduce recruitment response rates and participant availability, while working weeks and business hours differ between countries.
Include these factors in the feasibility assessment before agreeing a schedule. On larger studies, it may help to start difficult markets earlier. Markets that need to finish together do not necessarily need to launch on the same day.
9. Keep central control of the project
Clients should have a central point of contact who understands the whole study. That person needs a reliable view of recruitment progress, outstanding quotas, emerging risks and decisions required from the client. They should also ensure that screening standards are applied consistently and that recruiters and moderators have what they need.
Good international project management makes a complex study easier for the client to follow. Updates should be clear and consolidated, so the client does not have to piece together progress country by country.
10. Build contingency into the plan
International research rarely unfolds exactly as predicted. A market may prove harder to recruit, a participant may cancel, or translation may take longer than planned. What matters is how quickly the team identifies and manages those changes.
Before launch, consider where the greatest risks lie. Could recruitment use another suitable source? Could quotas move slightly without undermining the research? Should a difficult market begin earlier, and is there enough time for translation and review? Visibility and flexibility help the team resolve problems before they threaten the schedule.
What makes multi-country qualitative research successful?
Successful multi-country research balances comparable methods with local relevance. It depends on realistic feasibility assessments, appropriate recruitment and incentives, well-localised screeners, reliable participant checks, suitable moderation and central project management.
