What ethical principle requires that research participants are provided with enough information to make an informed decision about their participation?

The ethical principle that mandates that research participants receive sufficient information to make an informed decision about their participation is informed consent. This principle is fundamental in research ethics, as it ensures that individuals understand the nature of the study, what is expected from them, any potential risks or benefits, and their right to withdraw from the study at any time without penalty. Informed consent emphasizes the autonomy of participants, allowing them to engage in research voluntarily and knowingly.

Informed assent, while related, typically applies to situations involving minors or individuals who may not fully understand the implications of research participation. It involves obtaining an agreement from these individuals while still ensuring that their guardians provide informed consent.

Debriefing refers to the process that takes place after participation has concluded, which involves providing participants with information about the study's purpose and addressing any questions they may have. It is an important component of ethical research but does not pertain to the initial consent phase.

Confidentiality is an important ethical consideration regarding the privacy of participants' data and responses, ensuring that their identities and information are protected. However, it does not directly pertain to the provision of information necessary for making informed decisions about participation.

Therefore, informed consent is the key principle that encompasses the requirement for providing adequate information
