What is the purpose of reviewing the amount and method of payment to subjects?

• A. To maximize recruitment
• B. To assure that neither amount nor method presents problems of coercion or undue influence
• C. To standardize payments across trials
• D. To set payments high

Answer: (B)

The main idea is to prevent coercion or unduly influencing a person’s decision to participate. Payments should fairly compensate for time, travel, and burden without being so large or so easy to obtain that someone feels forced to join or stay in a study they would otherwise decline. The way payment is given also matters—the method should not create easy avenues for coercion or exploitation and should respect the participant’s autonomy. This keeps informed consent voluntary and helps avoid enrollment or retention biases that come from an overly influential payment. Options like trying to maximize recruitment, standardizing payments across trials without considering context, or simply raising the payment amount can all undermine ethical boundaries and integrity of the consent process.
