Recruitment and consent of women with intellectual disabilities in a randomised control trial of a health promotion intervention.

Background  The need for evidence-based health promotion interventions for women with intellectual and developmental disabilities is critical. However, significant barriers impede them from participating in research, including those related to recruitment and obtaining informed consent. Methods  This study describes a procedure for the recruitment and consent of women with intellectual disabilities into a community-based, multi-site randomised controlled trial. Results  Of 269 women who participated in information sessions, 203 (75%) enrolled in the study. While women with and without legal guardians consented at the same approximate rates (83% and 85%, respectively), those with legal guardians enrolled at significantly lower rates (61%) because of lower rates (74%) of guardian consent. Conclusions  It is possible to recruit community-dwelling women with intellectual disabilities into randomised controlled trials at relatively high participation rates. Recruiting women who have guardians poses additional challenges for researchers.
