Abstract
The informed consent form informs clinical research patients about the nature of the research and their rights, formalizing their decision to participate; however, studies show that this document is written in a complex manner, compromising patient autonomy. Two consent forms from the same hypothetical research were developed with different writing styles and analyzed by the Coh-Metrix Port tool, which evaluates linguistic metrics and textual accessibility. Results showed that both texts were complex and required high schooling level to be understood. These findings reinforce the perception that consent forms may have their real function compromised and point to the importance of changing its elaboration.
