The conduct of high quality clinical research is dependent on the ability to recruit and retain subjects who are invested in, understand, and have confidence in the clinical research process. Understanding subjects experiences as research volunteers is critical to the continual improvement of the processes of clinical research and, subsequently, to enhancing the subject s experience. Heretofore, studies evaluating the subject s comprehension of the informed consent process have served as, at best, an indirect measure of the quality of the subject s experience. Few, if any, studies have assessed the quality and efficacy of the entire clinical research process from the subject s perspective. This study is the first phase of a two-part study designed to directly measure research participants perceptions of all aspects of the clinical research process (e.g., recruitment, informed consent, education, autonomy and subject's rights, provision of clinical care) for the purposes of improving the clinical research subject s experience.
