Comments Off on 6 Ways to Improve Comprehension During Consent
Improve informed consent. Today more than ever, those three words resonate as both mantra and mandate for institutions, sponsors, research ethics boards, and regulatory agencies alike.
Echoing closely behind those three words are three more: increase participant comprehension. Ensuring participants have appropriate knowledge of a study (as well as their rights and responsibilities within it) is a crucial goal of the informed consent process—and a too-often elusive one: Researchers say that participants do not consistently understand or sometimes even read information in the consent forms for the studies they are joining., 
[ad name=”cf-wp-6-approaches” align=”right”]Studies of the informed consent process have documented the challenge of assuring participant comprehension—and offered possible solutions. The following is an overview of six research-based approaches that can improve informed consent and support participants’ understanding of the studies they are asked to join.
1. Apply health literacy best practices to consent forms.
Many studies indicate that consent forms with simpler diction and better design meaningfully enhance participant comprehension, as compared with their more complex and less visually accessible counterparts.
Research indicates that discussions between prospective participants and research staff (or independent educators) are more effective than any other intervention in improving participant comprehension during the informed consent process.
Teach-back—asking prospective participants to discuss the study in their own words—may allow for gauging comprehension and identifying gaps in participants’ understanding.
Research suggests that low literacy can hamper understanding of a study—even when efforts are made to improve the consent document or process.
Studies on the use of these methods in non-research settings show that they can meaningfully enhance patients’ knowledge of standard-of-care procedures—and experts suggest that they may offer similar value in research contexts. Note also that at least one study has verified the ability of decision aids to improve prospective participants’ knowledge during informed consent for clinical research.
6. Trust and support research staff.
Ensure that research team members have the time, support, resources, and training they need to understand a given protocol as well as prepare for and conduct informed consent discussions.
