Ethical standards for research involving persons with mental disabilities pursuant to the Convention on the Rights of Persons with Disabilities: a proposalPrincípios éticos para pesquisas com pessoas com deficiência intelectual de acordo com a Convenção sobre os Direitos das Pessoas com Deficiência: uma proposta

International ethical standards for research involving persons who have diminished decision-making capacity allow for delegation of the decision to participate in research to a representative who can act as a surrogate decision-maker. However, this approach has been questioned by the Convention on the Rights of Persons with Disabilities (CRPD), according to which all persons with disabilities, regardless of their mental or neurological condition, always have universal legal capacity to make decisions. The incompatibility between ethical standards and the CRPD is clear and impacts the conduct of research involving people with mental disabilities, which is essential for the improvement of their health and well-being. This article advances a proposal that seeks to reconcile the CRPD with ethical standards for informed consent processes in research and provides practical recommendations, especially for Latin American countries that still face challenges in implementing the CRPD in the research field.
