Informed consent is a cornerstone of research ethics. However, standard consent procedures often fail to ensure participants understand the content and consequences of their participation in research. This project will extend scientific understanding of informed consent in the social and behavioral sciences by probing participant comprehension of data sharing options and preferences for confidentiality. These issue areas have grown in importance as researchers aim to conduct work that is both ethical and transparent. This project involves three related activities. First, the development of a scoping review of past research on the topic. Second, an expert workshop to discuss current practices that aim to enhance ethical consent and research trade-offs in consent design decisions. And third, the collection of original data through focus groups with researchers who seek to obtain consent for surveys, as well as interviews with research participants. Findings from this project will inform researcher decision-making with respect to informed consent design choices and contribute to evidence-based recommendations about how to improve standard practices for obtaining consent. Participation in research is essential for the progress of the social and behavioral sciences, and ensuring genuinely informed consent is key to the ethical treatment of participants. This project seeks to advance scientific understanding of informed consent, focusing on two key issues. First, the project
