What is the purpose of informed consent in research involving human subjects?

The purpose of informed consent in research involving human subjects is to ensure understanding and voluntary agreement. Informed consent is a crucial ethical requirement that protects participants by providing them with all necessary information regarding the study, including its purpose, procedures, risks, benefits, and the right to withdraw at any time without penalty. This process allows participants to make informed decisions about their participation based on a comprehensive understanding of what the research entails.

By prioritizing understanding and voluntariness, researchers respect the autonomy of individuals, empowering them to participate in research that aligns with their values and preferences. This approach not only fosters trust but also enhances the ethical integrity of the research process, ensuring that participants feel comfortable and safe throughout their involvement.
