Study Types

Studies You Can Recruit For

If your study runs online, participants can take part from their own phone or computer.

Academic surveys

Questionnaires for social science, psychology, economics and health research.

Online experiments

Behavioral and cognitive experiments built in tools like Gorilla, jsPsych or PsychoPy online.

UX research

Unmoderated studies where participants complete tasks on a prototype and answer questions.

Cross-cultural studies

Run the same study in several countries and compare responses across cultures.

Diary and repeat studies

Short follow-up tasks over several days, launched as separate tasks for the same study.

AI and human-computer research

Studies where people interact with AI systems, rate outputs or describe their behavior.

How It Works

From Study Link to
Verified Participants

Build your study

Create your survey or experiment in any online tool and add a completion code on the final page.

Create the task

Paste your study link, describe the study, set the time and pay, and choose the countries.

Participants take part

Each participant opens the link, completes the study once and submits the completion code.

Approve and analyze

Approve participants with a valid code and complete data, reject the rest, then analyze your results in your own tool.

Data Quality

Screen Participants and
Protect Your Data

Country is selected in the task settings. Everything else is screened at the start of your study.

Country in task settings

Choose countries when you create the task. Age, language and experience are screened inside your study.

Screening questions

Add screening questions on the first page. Participants who do not qualify see a short end page and stop.

Attention checks

Use attention checks inside the questionnaire to spot careless responses.

Unique completion code

Give each study a unique code. Reject submissions with missing or invalid codes.

Completion time

Compare completion time with your expected duration and reject rushed submissions.

You approve every response

Review codes and answers, approve careful participants and reject the rest.

Fair Pay

Pay Participants Fairly

Fair pay brings more careful participants and better data. Set the pay per participant based on how long your study takes.

15-minute study

A typical short experiment or questionnaire session.

$2.25 per participant

Set the pay based on how long your study takes.

≈ $9.00 per hour

Ethics

Ethics and Consent Are Part of Your Study

Explain how the data will be used and follow the ethics rules of your institution.

Informed consent

Include an informed consent page at the start of your study and follow your institution’s ethics approval.

Adults only

Participants must be adults. Do not recruit minors through RapidWorkers tasks.

Minimize identifying data

Do not collect names, emails or other identifying data unless your study design and approval require it.

For Researchers

Built for Research Teams

University researchers

Recruit beyond student samples, in many countries.

PhD students

UX researchers

Test prototypes with real users outside your network.

Behavioral scientists

Run experiments with diverse, international samples.

Market and policy researchers

Reach people in emerging markets quickly.

AI researchers

Study how people use and judge AI systems.

Self-serve

Launch your study yourself

Paste your study link, choose countries, set the pay and approve participants by completion code.

FAQ

Frequently Asked Questions

How do I recruit research participants on RapidWorkers?

Build your study in any online tool, create a task with the study link, set the pay and choose the countries. Participants complete the study and submit a completion code, and you approve them.

Which survey and experiment tools can I use?

Any tool with a shareable link, such as Qualtrics, Google Forms, SurveyMonkey, Typeform, Gorilla or jsPsych. Add a completion code to the final page.

Can I screen participants by age, gender or other criteria?

Country is selected in the task settings. Other criteria are screened with questions at the start of your study. Participants who do not qualify see a short end page and do not continue.

Can the same person take my study twice?

No. Each participant can complete your task only once. For follow-up studies with the same people, ask our team about a managed setup.

How do I make sure responses are genuine?

Use attention checks, a unique completion code and expected completion times. Reject submissions with invalid codes or careless answers.

How much should I pay participants?

Set the pay based on study length. Many researchers aim for a fair hourly rate; the calculator shows what your pay means per hour.

Do I need ethics approval?

Follow the ethics rules of your institution. Include an informed consent page in your study, recruit adults only and avoid collecting identifying data you do not need.

What is the difference from survey responses for business?

This page is for academic and scientific studies. For customer and market research surveys, see market research surveys. For testing apps, see usability testing, and for rating AI outputs, see AI model evaluation.

Can I recruit participants in a specific country?

Yes. Choose one or more countries in the task settings, for example India, Kenya or Brazil, and set quotas per country if you need a balanced sample.

Can you manage recruitment for us?

Yes. Our team can set up the study task, plan country quotas, check completion codes and keep you updated until you reach your sample size. Contact us through the form below.
