What must be included in the written information provided to subjects regarding payment?

• A. Payment details should be provided verbally only
• B. The information regarding payment to subjects, including methods, amounts, and schedule, is set forth in the written informed consent form and any other written information; the prorating method should be specified
• C. Payment details should not be in consent
• D. Only the total payment amount is needed

Answer: (B)

Payments to participants must be disclosed in writing as part of the consent process so individuals understand what they’ll receive and when, before they agree to participate. The written information should spell out all details of compensation: how payment will be made (methods), the actual amounts, the schedule of when payments are issued, and any prorating method if participation is partial or ends early. This written clarity protects participants and provides a durable record that can be reviewed later, helping them make an informed decision and reducing the risk of misunderstanding or disputes.

Providing payment details verbally only can lead to memory lapses or misinterpretations, and omitting these details from the consent form or other written materials would leave participants without a documented, reviewable description of the terms. Including only the total amount omits important timing and mechanism information that can influence a participant’s assessment of the study. If payment terms change, those changes should be reflected in the written materials and re-consented as needed.
