Which additional safeguard is recommended for social and behavioral studies?

Removing all direct identifiers from the data as soon as possible is an important safeguard in social and behavioral studies because it protects participants' confidentiality and privacy. In these types of research, sensitive information may be collected that could lead to potential risks if individual identities are disclosed. By de-identifying data, researchers can minimize the potential harm to participants in the event of a data breach or if the findings are made public.

This practice encourages honest and open participation, as subjects are often more willing to share information when they know their identities are protected. Furthermore, de-identification aligns with ethical guidelines for research, emphasizing the need to prioritize participants' rights and well-being.

In contrast, other safeguards mentioned, while important in certain contexts, do not specifically address the unique challenges and considerations of social and behavioral research.
