What influences trust in and understanding of clinical trials? An analysis of information and communication technology use and online health behavior from the Health Information National Trends Survey

BACKGROUND

Using information and communication technologies to seek, discuss, and share health-related information influences people's trust and knowledge of several health practices. However, we know little about the associations between individuals' information and communication technology use and their perceptions of trust and knowledge of clinical trials. Examining these associations may lead to the identification of target audiences and channels for developing effective educational interventions and campaigns about clinical trials.

METHODS

In this study, we analyzed Health Information National Trends Survey data to document perceptions of clinical trial-related knowledge and trust that were recently added as questions in this annual national survey of US adults. We also examined correlates of these clinical trial perceptions that included sociodemographic factors and individuals' use of information and communication technologies to seek health information, discuss such information with their healthcare providers, and share the information in their network.

RESULTS

More than 90% of participants had no or limited perceived knowledge about clinical trials. Knowledge was higher among those who seek or discuss health-related information online. Differences in perceived knowledge and trust emerged for some racial/ethnic subgroups and other demographic factors. Providers were considered the most trusted source of information (73.6%), followed by health organizations (19.4%) and social support (7.1%). Trust in health organizations compared to health providers was higher among those who used online resources to share health information online with others. Trust in social support was significantly higher among those who used information and communication technologies to communicate about health.

CONCLUSION

Based on these findings, we recommend developing online resources about clinical trials to be distributed through social media. These resources should facilitate a dialogue and be targeted to several groups considering their information and communication technologies' use.

Latino recruitment to cancer prevention/screening trials in the Southwest: setting a research agenda

Examples of cancer prevention and screening trials in the Southwest are reviewed as a platform for highlighting gaps in research on Latino recruitment. Three trials are described, using "message/source/channel" categories as a framework. Each trial engaged community members to facilitate recruitment and developed tailored strategies to meet challenges emerging after recruitment began. Although we affirm that culturally relevant messages, community member referral networks, and adjustment to community realities seem important to Latino recruitment, current anecdotal and research findings do not allow evidence-based recommendations to be made. We suggest a research agenda to further illuminate critical factors for successful Latino recruitment.
