Abstract
This study aims to investigate the impact of personalized risk feedback and information utility framing on individuals' health self-assessments, emotional responses, and willingness to engage in preventive behaviors related to Chronic Kidney Disease (CKD), and how to alleviate information avoidance in health. We will recruit participants through an online platform and present them with a CKD prevention campaign. In the first stage, we will collect baseline data on subjective health predictions, and emotional state. Participants will also provide basic health information to generate a personalized CKD risk assessment. In the second stage, participants will be randomly assigned to one of three groups: a control group that does not receive their risk assessment, a feedback group that receives their personalized risk score, and an information utility group that receives the risk score along with tailored messaging designed to either reassure low-risk individuals or motivate high-risk individuals. The third stage will measure key outcomes, including willingness to pay for a home-testing kit, willingness to receive a kit by mail, and subsequent self-reported use of the kit. A follow-up will be conducted to assess changes in anxiety levels and other emotional status. The study will evaluate the causal effect of risk feedback and the additional impact of the information utility nudge on promoting preventive health behaviors.
