Payment of research participants: current practice and policies of Irish research ethics committees

Abstract

BACKGROUND: Payment of research participants helps to increase recruitment for research studies, but can pose ethical dilemmas. Research ethics committees (RECs) have a centrally important role in guiding this practice, but standardisation of the ethical approval process in Ireland is lacking. AIM: Our aim was to examine REC policies, experiences and concerns with respect to the payment of participants in research projects in Ireland. METHOD: Postal survey of all RECs in Ireland. RESULTS: Response rate was 62.5% (n=50). 80% of RECs reported not to have any established policy on the payment of research subjects while 20% had refused ethics approval to studies because the investigators proposed to pay research participants. The most commonly cited concerns were the potential for inducement and undermining of voluntary consent. CONCLUSIONS: There is considerable variability among RECs on the payment of research participants and a lack of clear consensus guidelines on the subject. The development of standardised guidelines on the payment of research subjects may enhance recruitment of research participants.
