When Respecting Autonomy Is Harmful: A Clinically Useful Approach to the Nocebo Effect

Area of Science:

• Medical Ethics
• Clinical Psychology

Background:

• Nocebo effects are adverse patient outcomes stemming from negative expectations.
• Informed consent procedures, while respecting patient autonomy, can inadvertently trigger nocebo effects through side-effect disclosure.

Purpose of the Study:

• To propose ethical guidelines for nondisclosure of information when nocebo effects are probable.
• To reconcile patient autonomy with the principle of nonmaleficence in clinical practice.

Main Methods:

• Building upon existing research by Wells and Kaptchuk (2012) and Cohen (2013).
• Developing a practical clinical framework for determining disclosure conditions.
• Integrating postencounter follow-up strategies.

Main Results:

• Suggests that ethical guidelines can permit nondisclosure to prevent likely nocebo effects.
• Advocates for prioritizing nonmaleficence over absolute adherence to informed consent in specific scenarios.
• Proposes a balanced approach to disclosure that respects ethical commitments.

Conclusions:

• Nondisclosure may be ethically permissible to prevent nocebo effects, upholding the principle of "primum non nocere."
• A practical clinical approach to disclosure and follow-up can maintain ethical standards while mitigating harm.
• Reconciles informed consent principles with patient well-being in the context of nocebo phenomena.
