As a parent, I've experienced two very different clinical trial consent processes with my son, and those experiences fundamentally shaped my understanding of health literacy in research.

My son participated in his first clinical trial when he was in elementary school. The study used a traditional paper-based consent process, and what should have been an opportunity to learn about the study became an exercise in endurance. I spent more than two hours in a room with a six-year-old who has ADHD, working through stacks of documents filled with dense information and medical terminology.

Like many parents in that situation, my focus shifted from understanding the content to simply getting through it. My son was required to provide assent, but he quickly lost interest. He bounced around the room, played with toys, and agreed to everything without truly engaging in the discussion. Although I knew the importance of informed consent, the process itself created barriers to comprehension. Faced with a restless child and an overwhelming amount of paperwork, I found myself skimming sections rather than carefully reviewing them.

The trial was non-invasive, so I wasn't overly concerned about missing critical safety information. However, when I left, I realized I had gained very little understanding of what participation would actually mean for our family. The consent process had technically delivered information, but it had not improved my health literacy. I did not walk away with a clear picture of the visit schedule, time commitments, or the practical impact the study would have on our daily lives. As the demands of participation became clearer over time, we ultimately withdrew because the travel and visit requirements became overwhelming.

A few years later, my son enrolled in a second clinical trial that used electronic consent. The difference was remarkable.

Instead of relying solely on lengthy text documents, the study incorporated videos, visuals, and interactive content designed to explain procedures and expectations in a way that was easier to understand. My son immediately connected with the experience. He was fascinated by videos showing the MRI procedures he would undergo and demonstrations of the online games that would be part of the study. Rather than tuning out, he became curious.

The multimedia approach transformed him from a passive participant into an engaged learner. He asked questions, sought clarification, and actively discussed what he was seeing. Those conversations deepened not only his understanding but also my own. Complex concepts became easier to grasp because they were presented in multiple formats rather than buried within pages of text.

Just as importantly, the process helped him feel included in the decision. Because we reviewed the information together and completed our signatures at the same time, he understood that his role mattered. He wasn't simply being told what would happen to him; he was being invited to participate in the conversation. That sense of ownership increased his engagement and confidence throughout the study.

When we left the electronic consent session, I felt prepared for what lay ahead. I understood the study requirements, visit schedule, and expectations in a way I never had during the paper-based experience. My son was even more prepared. He had memorized the schedule, understood what would happen at future visits, and looked forward to participating because he knew what to expect.

Looking back, the difference between the two experiences was not the amount of information provided. Both studies shared extensive information. The difference was how that information was communicated and whether it supported true understanding. Health literacy is not achieved when participants are handed a document; it is achieved when they can absorb the information, ask questions, connect it to their lives, and make informed choices with confidence.

For researchers and sponsors, this distinction matters. Better health literacy leads to better participant experiences, stronger engagement, and more informed decision-making. For patients and caregivers, it can mean the difference between feeling overwhelmed by a process and feeling empowered by it.

My experience showed me that when consent is designed around comprehension rather than compliance, everyone benefits. Electronic consent, when thoughtfully implemented, can be a powerful tool for improving health literacy and helping families fully understand the research journey ahead.
