Does every complaint mean the person wants to withdraw?

No. Listen separately to the outcome they want; raising a concern does not automatically change their participation decision.

Is site permission needed before using an independent route?

Do not add an unnecessary permission barrier. Follow approved information and applicable local arrangements for the relevant reporting pathway.

Making Participant Complaint Routes Understandable

Participants should know whom to contact within the study and which independent route is available when they have a concern. A telephone number printed on a form does not prove that the pathway is understood. Complaints and clinical safety questions may require different referral routes.

Define the workflow

Separate scheduling problems, concerns about the research and urgent health needs. Keep independent contact information current and consistent with approved materials. Do not obstruct access by telling someone they must first reach an agreement with the local team before using an appropriate independent channel.

Worked example

For example, a participant wants to report pressure from a staff member but thinks they must call that same person. The centre explains an appropriate alternative route and addresses the concern through the authorized process. The person named in the complaint should not negotiate with the participant to withdraw it.

Practical checks

Ask participants to explain which contact they would use in different situations.
Periodically confirm that independent contact details remain current and accessible.
Define responsibilities that prevent pressure or adverse treatment because someone raises a concern.

Decision and boundaries

A useful route makes reporting easier and describes realistic next steps. Do not invent investigation outcomes or guaranteed resolution times. Refer a report involving clinical risk to the appropriate investigator as well; complaint handling should not delay safety assessment. Share personal information only with necessary authorized people, avoiding unnecessary broad distribution.
