Willingness to share information on social media: a systematic literature review (2020-2024).

INTRODUCTION

The rapid advancement of Web 2.0 technologies, accelerated by the COVID-19 pandemic, has fundamentally transformed information sharing behaviors on social media. This transformation necessitates a comprehensive understanding of the factors influencing information sharing willingness in the digital era.

METHODS

This study systematically reviews 66 peer-reviewed journal articles published between 2020 and 2024, focusing on key research topics, theoretical frameworks, and methodologies used to examine information sharing willingness on social media. Following the PRISMA guidelines, articles were identified and analyzed using keyword matching, thematic categorization, and expert review.

RESULTS

Our findings reveal four core research themes: general information sharing, health-related information sharing, false information dissemination, and crisis information sharing. These themes are examined through three primary theoretical perspectives: motivational-driven theories, cognitive-processing theories, and social-relational theories. The study identifies key factors influencing information sharing willingness across motivational, cognitive, and social dimensions. Methodologically, survey-based studies dominate this field, with experimental designs providing supplementary insights.

DISCUSSION

This review contributes to the literature by providing a holistic synthesis of the current research landscape, identifying gaps in knowledge, and proposing potential directions for social media platform operators and policymakers to consider. Future research directions are proposed to address unresolved challenges and advance the theoretical and methodological understanding of information sharing behavior in the digital era.
