“…The small but growing literature on the attitudes of marginalized groups to nonintervention research on illicit drug use and HIV risk has focused on issues of trust between drug users and research recruiters, perceived risks and benefits of research participation and the effect of monetary inducements on motives to participate (Barratt, Norman, and Fry, 2007; Fisher and Ragsdale, 2006; Fisher et al, in press; Fry and Dwyer, 2001). This research suggests that recruitment of historically marginalized populations may be compromised by participants’ mistrust of the scientific establishment in general (Herek and Blunt, 1988; Shaw, 2005; Singer, 1993; Stevenson, DeMoya, and Boruch, 1993; Swanson and Ward, 1995) and of researchers’ motives, competence, and commitment to confidentiality and participant’s welfare in particular (Fairchild and Gayer, 1999; Fisher and Wallace, 2000; Fisher et al, 2008; Fitzgerald and Hamilton, 1996). …”
