“…Researchers may choose to pay participants for various reasons (Gelinas et al, 2018), such as to bolster recruitment efforts (Bentley & Thacker, 2004; Ripley, Macrina, Markowitz, & Gennings, 2010b), compensate for study-related costs, time, and inconvenience (Fry et al, 2005; Mweemba, Ali, & Hyder, 2018), and as a way to show appreciation for participants’ contributions (Resnik, 2015). Research shows that amounts and forms of payment for research participation vary widely (Fry et al, 2005; Latterman & Merz, 2001; Marathe et al, 2018). Some research also shows that payment amounts depend on the research setting, the amount of time that research participation requires, the procedures that participants will experience, and the type of research (e.g., early phase clinical experiments vs. late-phase clinical trials or biomedical vs. sociobehavioral research) (Fry et al, 2005; Marathe et al, 2018; Mweemba et al, 2018).…”
