Research Participant Perception of Care Project: Part II: Fielding and Validation of the Research Participant Perception Survey Derived From Focus Group-Identified Key Dimensions of the Research Participant Experience

Background: * Understanding participants experiences as research volunteers is critical to improving the effectiveness of human participant protection programs and strengthening public trust in clinical research. Historically, studies that evaluate participants comprehension of the informed consent document or evaluate the informed consent process have only indirectly measured the quality of a participant s experience. * Few studies have assessed the nature, quality and efficiency of the entire clinical research process from the participant s perspective. To address this need, researchers have developed a Clinical Research Participant Perception Survey to evaluate participants overall perceptions of clinical research. Objectives: \- To validate the Research Participant Perception Survey questionnaire and revise it accordingly to produce a questionnaire that other researchers can use. Eligibility: \- Individuals at least 18 years of age who have participated in at least one research protocol within the past 2 years. Participation may be completed or ongoing. Design: * Eligible participants will receive a survey by mail and will be asked to complete it and return it in the stamped envelope provided. * The survey will ask questions about the research protocol process, including participants positive and negative experiences of participating in the research protocol....
