NCT05505058

Brief Summary

Ethical research on detained persons remains limited, including research on informed consent. This study aimed to fill in this research gap and compared audio-visual and paper-based materials for a one-time general informed consent for research in prison, using a randomized design. The primary outcome was whether participants sign the inform consent. Secondary outcomes included understanding, evaluation, and time to read/watch the informed consent.
