A linguistic model of informed consent.

The current disclosure model of informed consent ignores the linguistic complexity of any act of communication, and the increased risk of difficulties in the special circumstances of informed consent. This article explores, through linguistic analysis, the specificity of informed consent as a speech act, a communication act, and a form of dialogue, following on the theories of J.L. Austin, Roman Jakobson, and Mikhail Bakhtin, respectively. In the proposed model, informed consent is a performative speech act resulting from a series of communication acts which together constitute a dialogic, polyphonic, heteroglossial discourse. It is an act of speech that results in action being taken after a conversation has happened where distinct individuals, multiple voices, and multiple perspectives have been respected, and convention observed and recognized. It is more meaningful and more ethical for both patient and physician, in all their human facets including their interconnectedness.
