Objective:

To analyze the impact of perceived risks, benefits, digital literacy, and interpersonal trust on the willingness to share patient-generated health data (PGHD) among Korean internet users, utilizing privacy calculus and communication privacy management frameworks.

Key Findings:

• Digital literacy and interpersonal trust are hypothesized to positively influence the willingness to share PGHD, suggesting that higher levels of these factors may lead to increased sharing.
• Perceived risks negatively impact the willingness to share PGHD, indicating that concerns about privacy may deter individuals from sharing their data.
• Perceived benefits positively influence the willingness to share PGHD, highlighting the importance of understanding the advantages that users associate with sharing their health data.

Interpretation:

The study aims to enhance understanding of factors affecting the sharing of PGHD, particularly in the context of digital health care in Korea, and to inform strategies for improving user engagement in health data sharing.

Limitations:

• Previous studies primarily focused on specific disease patient groups or small samples, limiting the generalizability of findings.
• Limited research on the general public's understanding of PGHD, which may affect the applicability of results to broader populations.

Conclusion:

The study seeks to identify factors influencing the decision to share PGHD to improve digital health care services, with implications for future research and practice in the field.
