Open Government Data (OGD) initiatives have become increasingly crucial for promoting transparency, increasing efficiency, and encouraging citizen engagement in public administration. However, organizations' successful adoption of OGD, especially government agencies, depends on various factors. This study extends the Unified Theory of Acceptance and Use of Technology (UTAUT) model by integrating perceived risk as a critical construct affecting OGD adoption in Tanzania. Recognizing that data accuracy, privacy, and security concerns can hinder user engagement, the study explores how perceived risk interacts with the original UTAUT dimensions: performance expectancy, effort expectancy, social influence, and facilitating conditions. Using a quantitative methods approach, the study surveyed a diverse sample of potential OGD users. The analysis reveals that perceived risk positively correlates with behavioral intentions toward OGD adoption. This implies that addressing perceived risk is essential for enhancing OGD adoption strategies, particularly in this field where security and privacy concerns are paramount. This study contributes to the existing body of knowledge by providing practical insights for developers, practitioners, and policymakers aiming to facilitate user engagement in an increasingly OGD adoption.
