Multilingual qualitative research introduces quality risks that monolingual research does not face. This checklist covers the critical quality controls for each stage of a multilingual research study.
Pre-Study Design Checklist
- Research objectives are defined in culturally universal terms (not English-specific question wording)
- Discussion guide focuses on objectives, not translated questions
- Screening criteria are appropriate for each target market
- Sample size per language is sufficient for thematic saturation (minimum 15-20 per language for focused questions)
- Cultural communication differences are accounted for in study design
- Interview duration expectation accounts for cultural variation in response length
Participant Recruitment Checklist
- Recruitment channels are appropriate for each market (not just global panel with language filter)
- Screening verifies genuine language proficiency, not just self-reported ability
- Sample composition is representative of the target population in each market
- Incentive levels are appropriate for each market’s economic context
- Recruitment does not systematically exclude non-digitally-native populations
Data Collection Checklist
- AI moderation is native-language, not translated scripts
- Probing depth is consistent across languages (adapted technique, not reduced depth)
- Original-language transcripts are preserved alongside translations
- Code-switching (participants switching between languages) is handled appropriately
- Interview completion rates are monitored per language for systematic drop-off
Analysis Checklist
- Within-culture analysis completed before cross-market comparison
- Theme codebooks developed independently per language before cross-language synthesis
- Cultural response style accounted for before comparing sentiment intensity across markets
- Key findings verified against original-language verbatims
- Culturally specific themes preserved (not collapsed into generic categories)
- Translation artifacts identified and flagged
Reporting Checklist
- Cross-market findings clearly distinguished from market-specific findings
- Cultural context provided for market-specific insights
- Original-language verbatim quotes included alongside translations for key findings
- Methodology limitations documented (especially regarding cultural representation)
- Recommendations differentiated by market where relevant
