2.2. Phase 1
The primary aim of the study was to identify barriers and facilitators impacting clinical trial participation. This involved assessing the potential of a mobile application to mitigate these barriers and enhance participation rates among subjects. Furthermore, the study aimed to discern the optimal messaging and strategies required to motivate subjects to engage in clinical trials, ascertain preferred sources and media for receiving information, and determine pertinent content for the personalized newsfeed feature within the mobile app. Additionally, we created a journey map depicting the path to clinical trial participation, which enabled the identification of bottlenecks, decision points, and associated barriers and facilitators throughout the clinical trial journey.
