[Informed consent: a dialogic praxis for the research].

The informed consent is a process in which a person agrees to participate in a research, knowing the risks, benefits, problems or consequences that may arise during developing it. The aim of this study is to collect the characteristics of the informed consent process (ICP) so its understanding and compliance allow an ethical dialog, thoughtful and responsible exercise for the researcher. We present the results of an extensive review of the ICP elements from its components to their legal and ethical foundation, including the myths and realities that exist about the format of informed consent as a legal protection. The informed consent is not an established format that researchers reproduce in their research, but its praxis is a daily task in the research with human subjects as critical, deliberative, and committed communication between two moral agents: the researcher and the researched one.
