Use the survey platform your university has approved for research, and choose among the four below by research situation: REDCap for health and clinical work where your institution provides it, Qualtrics for complex logic or experiments where it holds a licence, LimeSurvey when you need control over hosting, and Microsoft Forms for simple surveys and pilots.
| Platform | What the vendor says it is | Access | Logic and question types | Data location | Best for | Watch out |
|---|---|---|---|---|---|---|
| Qualtrics | A survey platform with a wide array of question types, with options to customise which questions appear when | Overview page does not address licensing; some features are add-ons; ask your institution | Wide array of question types; display customisation; distribution by email, SMS or anonymous link | Check your institution’s configuration | Complex logic and experiments where licensed | Feature availability depends on the licence |
| REDCap | A secure web application for building and managing online surveys and databases for research studies | Free to non-profit organisations that join its consortium; access normally through your institution | Surveys and databases; multi-site studies; online and offline capture | Depends on your institution’s installation | Health and clinical research; longitudinal databases | You cannot sign up alone; needs an institutional account |
| LimeSurvey | An open-source survey tool with a public codebase, cloud or self-hosted | Cloud service with a free survey to start, or self-hosted | Over 30 question types; logic and branching | Choose a data centre (EU, US and more) or a dedicated server | Control over hosting and customisation | Self-hosting needs technical support and approval |
| Microsoft Forms | Create surveys, quizzes and polls and see results as they come in | Microsoft 365 school or work credentials, or a Microsoft account | Choice, text, rating, date, ranking, Likert, file upload and Net Promoter Score questions; sections; branching logic | Depends on the account and tenant | Simple surveys and pilots | Check which accounts and settings your university approves |
How should you choose a survey platform for a PhD?
Start from your approvals, not from the features. An ethics committee approves a protocol that names a platform, so the safest choice is one that your university already supports for research and that your data protection officer can describe in a sentence. If your department has a standard platform, use it unless you have a design reason not to. If you do have a reason, such as a complex experiment with randomised blocks, a longitudinal database or a need to host data yourself, write that reason into the ethics application.
The four platforms differ in who controls access. REDCap is almost always obtained through an institution. Qualtrics depends on your institution’s licence. Microsoft Forms depends on the account you use. LimeSurvey can be run in the cloud or self-hosted. The comparison below takes each in turn using what the vendors themselves say on their pages, and then turns to the questions an ethics committee will ask.
What is Qualtrics good for, and what should you check?
Qualtrics’ survey platform overview says you can pick from a wide array of question types, customise what questions appear to respondents and when, send surveys by email, SMS or a single anonymous link, and look at data inside the platform or export it for analysis in other software. It suits complex designs, such as surveys with extensive display logic or randomised conditions. The overview page does not address licensing at all. It notes that some features are add-on features not included in standard licences and directs users to an account executive, so the practical step is to ask your library or IT service whether your university holds a licence and exactly which features it includes. Do not design a survey around a feature that your licence may not contain.
Why is REDCap so common in health research?
REDCap describes itself as a secure web application for building and managing online surveys and databases, designed for online and offline data capture for research studies. It is run by a consortium of institutional partners, says it is free to non-profit organisations that join, and says that organisations gain access by joining the consortium, with individuals reaching it through their institutional affiliation. Its page lists support for a range of regulatory frameworks, including GDPR, as a claim by the platform; it is not a substitute for your own institution’s approval of how it is configured. It also supports multi-site studies and export to standard statistical software, which is why it is common in clinical and public health research, including projects that sit alongside the governance steps described in how to write the methodology chapter of a nursing PhD thesis. The limitation for a student is that you cannot sign up alone: you need your university or hospital to provide an account.

When does LimeSurvey make sense?
LimeSurvey describes itself as open source with a public codebase, and offers both cloud and self-hosted deployment. Its homepage says you can choose your preferred data centre, including EU and US options, or host surveys on a dedicated server, lists over 30 customisable question types and logic and branching, and offers a free survey to start. Control over where data sits is the main reason to choose it: if your ethics committee or a data-sharing agreement requires specific hosting, a platform where you can state the location precisely is easier to approve. The cost of that control is responsibility. If you self-host, someone has to maintain the server, apply updates and manage backups, and your university may need to approve the arrangement.
Is Microsoft Forms enough for a PhD survey?
For many designs, yes. Microsoft’s support page says you can create surveys, quizzes and polls and see results as they come in, with question types including choice, text, rating, date, ranking, Likert, file upload and Net Promoter Score, plus sections and branching logic. It is available with Microsoft 365 school or work credentials or a Microsoft account. That final point is the one to check with your university: use of a personal account for research data is unlikely to be what your ethics approval describes, while use of the university’s own Microsoft 365 account may be exactly what it expects. Forms is a sensible tool for short surveys, quick pilots and consent-light studies, and less suited to complex randomisation or longitudinal participant tracking.

What will an ethics committee ask about the platform?
The same questions arise whichever platform you choose, and a prepared answer shortens approval.
- Which platform and who hosts it? Name the platform and the organisation that is its data processor.
- Where is the data stored? State the location as your institution or the vendor documents it. If you cannot state it, ask your data protection officer before you apply.
- How are responses anonymised or pseudonymised? Say whether the platform records identifying metadata and whether you have switched that off, if the platform allows it.
- How is consent captured? The first page should carry the information sheet and a consent statement, and participants should not reach the questions without agreeing.
- Who has access, for how long, and how is data deleted or exported? Name the people, the retention period and the deletion step.
- What happens to the survey link? Say how it is distributed and whether it can be forwarded, and how you guard against duplicate responses.
A sensible approach to unpublished or sensitive data more broadly is set out in whether it is safe to put unpublished thesis data into an AI tool, and the same questions of terms, data location and retention apply to a survey platform.
What about licensed scales and survey design?
Building a survey is not only a software question. If your questionnaire includes a proprietary scale, you need the publisher’s permission before you reproduce its items in an online form; the Maslach Burnout Inventory, for example, is sold under a licence, as explained in writing a PhD on burnout. The reliability and validity evidence you will report is a separate step covered in what examiners expect on validity and reliability, and the design of items, matrices and pilots is in how to design data collection instruments for postgraduate research. Pilot on the final platform. A pilot tests logic, timing, mobile display and data export as well as the wording, and an export that arrives with unreadable variable names is better discovered at the pilot than at analysis.
Which platform for which situation?
| Your situation | Likely choice | Why |
|---|---|---|
| Clinical, NHS-linked or longitudinal study with a hospital or university REDCap installation | REDCap | Built for research data capture; institutional hosting is already approved |
| Experiment with randomised blocks or complex display logic and an institutional licence | Qualtrics | Rich logic and distribution options; confirm licensed features first |
| A funder or partner requires specific hosting, or you want full control | LimeSurvey | Choice of data centre or self-hosting |
| Short cross-sectional survey or pilot using university Microsoft 365 accounts | Microsoft Forms | Simple, widely available, accepted question types |
Whichever you choose, a sample-size plan comes before the survey link goes out. Sample size rules for postgraduate nursing and health research sets out the reasoning that applies to most doctoral surveys.
A worked illustration of the ethics-application wording
The following is an invented example of how a short platform paragraph might read in an ethics application, to show the level of specificity committees expect. It is illustrative, and you should replace each statement with what is true for your institution and your platform.
- “The survey will be hosted on the university’s approved platform, administered under my university account, and the data processor and storage location are as documented by the university’s data protection office.”
- “Participants receive the information sheet on the first page and cannot proceed without ticking the consent statement. No names, email addresses or IP addresses are collected as part of the responses.”
- “Responses are exported to the university’s secure research drive, analysed there, and the survey and its responses are deleted from the platform within the retention period stated in the data management plan.”
Each statement answers one of the six questions above. If you cannot truthfully write a sentence like these for your chosen platform, that is the sign to choose a different platform, or to ask your data protection officer how to configure the one you have.
Frequently asked questions
Which survey platform is best for a PhD?
There is no single best platform. Use the one your university supports and has already approved for research, then choose among REDCap for health and clinical work, Qualtrics for complex logic or experiments if your institution holds a licence, LimeSurvey if you need control over hosting, and Microsoft Forms for simple surveys and pilots.
Is REDCap free for PhD students?
REDCap says it is free to non-profit organisations that join its consortium, and individuals normally access it through their institutional affiliation, so you need your university to provide an account.
Do I need a licence to use Qualtrics?
Qualtrics’ own overview page does not address licensing and points to an account executive for specifics, noting that some features are add-ons not included in standard licences. Ask your library or IT service whether your university holds a licence and which features it includes.
Can I choose where LimeSurvey stores my data?
LimeSurvey states that you can choose your preferred data centre, including EU and US options, or host on a dedicated server, and it can also be self-hosted as open-source software.
Can I use Microsoft Forms for a PhD survey?
Yes for many designs. It supports Likert, rating, ranking and other question types with branching logic, and is available with Microsoft 365 school or work credentials or a Microsoft account. Check your university’s policy on which accounts and settings are approved for research data.
What does an ethics committee want to know about the platform?
The platform name, who hosts the data and where, how responses are anonymised or pseudonymised, who has access, how long data is kept and how it will be deleted or exported. Ask your data protection officer for the university’s approved wording.
Can I put a licensed scale such as the MBI into an online survey?
Only with the publisher’s permission. Many scales are proprietary, and licence terms govern how items may be reproduced and administered, so check before you build the survey.
Should I pilot on the same platform?
Yes. A pilot on the final platform tests logic, timing, mobile display and export as well as the wording.
Is it acceptable to use a free consumer survey tool?
Only if your university’s data policy and ethics approval allow it. Consumer tools often have different terms for data location and reuse, so an approved institutional platform is usually safer.
Where the survey fits in the thesis
The platform decision shows up in the ethics application, the methods chapter and the data management plan, and all three have to say the same thing. Tesify is used by 9,000+ students across 15,000+ chapters to organise a thesis chapter by chapter, and the thesis stays 100% written by you. Your choice of platform and the approvals behind it are yours; a chapter plan helps you check that the methods chapter, the ethics paperwork and the data plan agree.
