Help keep listings accurate
Report a Listing
Tell us about an expired, inaccurate, misleading, or concerning opportunity.
What should you include?
Include the listing title or URL, the provider name, and what appears incorrect or unsafe. We review reports but cannot guarantee a provider’s selection or payment decision. Never send a password, Social Security number, medical record, or payment-card information.
For questions about screening, participation, or an unpaid reward, contact the research provider directly first. Providers control qualification and payment.
