Payment
There are four main forms of payment in research.
1. Reimbursement payments – when children and/or parents are paid to cover the direct expenses related to participation.
2. Compensation payments – in which children and/or parents are recompensed for their time, work and effort, and for any inconvenience caused by participation.
3. Appreciation payments – bonuses or tokens given to children after their participation to thank them for their contribution (these are often not disclosed during recruitment to reduce coercion).
4. Incentive payments – which are designed to encourage the participation of children in research.
