“…The finding that studies involving children paid more than studies involving nonstudent adults and college students is interesting, particularly in light of the ethical debate surrounding research payments to children (Bagley, Reynolds, & Nelson, 2007; Iltis, Matsuo, & DeVader, 2008; Ross, 2005; Wendler, Rackoff, Emanuel, & Grady, 2002). Specifically, there are concerns that children are more susceptible to undue influence from payment, and have limited capacity to understand the requirements of participation and the potential risks of participation (Taplin et al, 2019). However, considering that nearly all of our data came from minimal risk studies and the relatively low payment levels (the highest being USD 120 for a 46.5-hr study across 14 weeks), it is unlikely that child research participants were unduly influenced (Taplin et al, 2019; Wendler et al, 2002).…”
