REDCap and Qualtrics are the two dominant research survey platforms at universities worldwide. They are not interchangeable - they serve different research contexts and have fundamentally different architectures. REDCap is open-source, runs on institutional servers, and is the standard for clinical and health research. Qualtrics is enterprise SaaS, runs in the cloud, and is standard for social science, CX, and population survey research. This guide covers when each is the right choice.
Core Differences
| Feature | REDCap | Qualtrics |
|---|---|---|
| Architecture | Self-hosted on institutional servers | Cloud SaaS (AWS) |
| Data location | Your institution's own servers | Qualtrics US/EU data centres |
| HIPAA compliance | Yes - on institutional servers (no BAA needed) | Yes - on enterprise plan with BAA |
| PHI / sensitive health data | Designed for this - standard use | Possible with BAA - requires configuration |
| Cost | Free (consortium membership) or free (institution covers) | Institutional licence (significant cost) |
| Longitudinal data | Built-in - events, arms, repeat instruments | Possible but requires workarounds |
| GCP compliance (clinical trials) | Yes - audit logs, user roles, validation | Not designed for GCP-regulated trials |
| Survey design UI | Functional - complex for non-technical users | Highly polished - drag-and-drop |
| Analytics and reporting | Basic built-in - exports to R, Stata, SPSS | Advanced - dashboards, Text iQ, Stats iQ |
| Question types | Comprehensive for clinical data | Comprehensive for survey research |
| Branching / display logic | Expression Manager (syntax-based) | Display Logic (visual builder) |
Use REDCap When
- Your research involves Protected Health Information (PHI) or sensitive health data
- You are running an FDA-regulated clinical trial requiring GCP-aligned audit trails
- Your study is longitudinal with multiple time points, repeat instruments, or multiple arms
- Your ethics approval or institutional policy requires data on institutional servers
- You need built-in randomisation, data quality rules, or clinical trial management features
- You are at an institution in the REDCap Consortium (6,500+ institutions - no additional cost)
Use Qualtrics When
- Your research is social science, psychology, marketing, education, or CX focused
- You need advanced survey features: conjoint, MaxDiff, heatmap questions, video embedding
- You want real-time dashboard analytics and cross-tabulation in the platform
- You need to distribute to an external panel (Qualtrics XM Directory or partner panels)
- Your study does not involve PHI and cloud data storage is acceptable to your institution
- Your institution has a Qualtrics licence (most major universities now do)
Converting the Same Instrument to Both
Multi-method studies sometimes need the same instrument in both REDCap (for the clinical arm) and Qualtrics (for the population survey arm). Pirai AI converts the source Word or PDF document to both REDCap Data Dictionary CSV and Qualtrics QSF from a single upload in one session. No double entry, no second upload. Both outputs use verbatim text from the approved instrument.
Frequently Asked Questions
Use REDCap for clinical research involving PHI, GCP-regulated trials, longitudinal studies with repeat instruments, and research requiring data on institutional servers. Use Qualtrics for social science, psychology, education, marketing, and CX research where cloud data storage is acceptable and advanced survey features (conjoint, panels, dashboards) are needed.
REDCap on institutional servers is HIPAA compliant - data stays within your institution's own infrastructure covered by your HIPAA Security Rule compliance programme. No Business Associate Agreement with a third-party cloud vendor is required. This is REDCap's key advantage over Qualtrics for US health research involving PHI.
Qualtrics can be used for non-GCP clinical research surveys when HIPAA compliance is configured (enterprise plan with BAA). For FDA-regulated clinical trials requiring GCP-aligned audit trails, longitudinal data with defined events and arms, and validated system compliance, REDCap is the more appropriate choice.
Yes. From a single document upload in Pirai AI, export to both REDCap Data Dictionary CSV and Qualtrics QSF in the same session. Both outputs use verbatim text from the source document. Convert once for both platforms without re-uploading or re-entering questions.
