This study (Specific Aim 2 of the linked study protocol) will compare the effectiveness of the interactive, trust-enhanced consent application to an interactive consent and standard consent (no interactivity, no trust- enhancement) using a randomized trial of the three consents with 750 adults in a network of family medicine practices. Primary outcomes will be satisfaction with the consent decision and understanding of the consent content.
Conceptually, the hypothesized effectiveness of this study's new consent application relies on two constructs, interactivity and trust. Many studies have identified the importance of trust in researchers when it comes to people's willingness to participate in research. Moreover, trust in the source of information is critical to participants' evaluations of risk information. And, risk information is an important element of the research consent process. Thus, highlighted relevant messages to participants at the outset of a research consent process. It is expected that these messages will not coerce participants nor will they dramatically alter participants' general trust in researchers. More importantly, empirically assessments of both of these expectations to ensure the application delivers an ethically appropriate consenting experience. However, it is expected that presenting key facts about research data protections, researcher training, and research regulations will increase the likelihood that participants will be willing to learn about research using medical records. In turn, this will increase participants' understanding and help them make a more informed decision. In the absence of these trust-related messages, it is expected that many participants will simply disengage from the details of the consent information and thus make a less informed decision about participating. Next, the investigators' use of interactivity is supported by research on the effectiveness of communications that interactively deliver detail, empower audiences, and allow a self - discovery process. Indeed, an interactive, person-to-person consent process is the standard approach in clinical trials. Therefore, in the new consent application, the interface will allow participants to interactively explore the details that are most important for their personal understanding of research using EHRs and most relevant to their personal information needs and satisfaction with the consent decision. Without this interactive information exploration, which is essentially dynamically tailored to their personal information needs, participants are more likely to be overwhelmed by the volume of information presented and unable to obtain the information they want most. Under these circumstances, participants' overall understanding of the consent information is likely to decrease, and they are likely to make less satisfactory decisions. There are two specific hypotheses: (1) compared to the standard consent, the interactive consent will lead to increased decisional satisfaction and understanding of the consent; and (2) compared to the interactive consent, the interactive, trust-enhanced consent will lead to increased decisional satisfaction and understanding of the consent.
