Informed consent, vulnerability and the risks of group-specific attribution.

Area of Science:

• Nursing Research Ethics
• Participant Protection
• Vulnerable Populations

Background:

• Individuals in extraordinary situations are vulnerable to research-related harm, exploitation, and abuse.
• Informed consent, based on self-determination, is challenged in nursing research due to participant dependencies (age, illness, frailty).
• Excluding vulnerable populations violates ethical principles of justice and beneficence; attributing vulnerability to groups can lead to stigmatization.

Purpose of the Study:

• To explore how to protect vulnerable individuals in clinical nursing research without compromising ethical principles.
• To propose an alternative framework for understanding and addressing vulnerability in research contexts.

Main Methods:

• The study critically examines the concept of vulnerability in research ethics.
• It proposes the adoption of relational ethics as a framework for understanding vulnerability.
• The research integrates this contextual understanding of vulnerability with existing informed consent models.

Main Results:

• Vulnerability is redefined as a situational and relational concept, dependent on a person's health status and their relationship with the research context.
• This relational approach avoids stigmatizing individuals by not solely attributing vulnerability to group membership.
• Balancing ethical principles (autonomy, justice, beneficence, non-maleficence) is achievable through a context-aware approach.

Conclusions:

• Relational ethics provides a viable approach to protect vulnerable research participants.
• Viewing vulnerability as situational allows for a more nuanced and ethical balance of research principles.
• This framework supports the inclusion of vulnerable populations in research, ensuring their needs are met and ethical standards are maintained.
