Do research intermediaries reduce perceived coercion to enter research trials among criminally involved substance abusers?

We examined the efficacy of including a research intermediary (RI) during the consent process in reducing participants' perceptions of coercion to enroll in a research study. Eighty-four drug court clients being recruited into an ongoing study were randomized to receive a standard informed consent process alone (standard condition) or with an RI (intermediary condition). Before obtaining consent, RIs met with clients individually to discuss remaining concerns. Findings provided preliminary evidence that RIs reduced client perceptions that their participation might influence how clinical and judicial staff view them. This suggests that using RIs may improve participant autonomy in clinical studies. © 2011 Taylor & Francis Group, LLC.
