[Mental competence and informed consent. Clinical practice and ethical analysis].

Area of Science:

Background:

• Informed consent is a cornerstone of medical ethics and law in psychiatry.
• Psychiatric disorders can impair a patient's capacity to provide informed consent.
• Assessing competence for treatment decisions and clinical trials in psychiatry is complex and controversial.

Purpose of the Study:

• To examine the challenges in assessing informed consent capacity in psychiatric patients.
• To present empirical data on the prevalence of incompetence among psychiatric patients.
• To propose a framework for ethically sound competence assessment in clinical practice.

Main Methods:

• Review of ethical and legal standards for informed consent in psychiatry.
• Analysis of empirical data on the capacity of psychiatric patients to make treatment decisions.
• Exploration of a sliding scale model for competence assessment.

Main Results:

• A significant percentage of psychiatric patients demonstrate incompetence in providing informed consent based on established standards.
• The assessment of competence is a contentious issue within psychiatric practice.
• A sliding scale approach to competence assessment is suggested to balance autonomy and beneficence.

Conclusions:

• Ethical challenges arise when psychiatric patients lose decision-making capacity.
• A high proportion of psychiatric patients may be unable to provide informed consent.
• A sliding scale model offers a practical approach to assessing competence, integrating key ethical principles.
