The use of an educational video during informed consent in an HIV clinical trial in Haiti.

Background: Research volunteers from developing countries who enroll in HIV clinical trials may be illiterate and unfamiliar with the conduct of medical research. Educating volunteers about the contents of the consent form is essential but can be difficult and time consuming. We evaluated the feasibility and effectiveness of an educational video during the informed consent process for an HIV clinical trial conducted in Port-au-Prince, Haiti.
