Survey and Panel Fraud: Protect Respondent Quality

What to understand

Survey and panel fraud can involve repeated participation, misrepresented eligibility or automated responses. A response can be complete while still failing the study's requirements. Screening should connect participant context with response quality and the rules of the research program.

Review participation and eligibility

Compare repeat identifiers, entry sources and activity across invitations. Evaluate whether the same person could be claiming a restricted opportunity repeatedly. Shared networks and devices can also reflect genuine participants, especially within households or institutions.

Signals to review together

Repeated participation and fabricated responses can influence findings before anyone notices the sample is compromised.

• Participant Links: Review duplicate participation
• Response Quality: Assess consistency and attention
• Timing Patterns: Compare completion behavior
• Location Context: Check fit with recruitment criteria

Combine fraud and research-quality checks

Consider response coherence and study-specific quality indicators alongside device, contact and network context. Fast completion alone can reflect familiarity or a short survey. Assess whether screening changes improve usable responses without distorting the intended sample.

Keep legitimate activity in view

Fast completion or a shared network is a reason to review, not an automatic exclusion.
