A Vision to Enhance Trust Requirements for Peer Support Systems by Revisiting Trust Theories

This vision paper focuses on the mental health crisis impacting healthcare workers (HCWs), which exacerbated by the COVID-19 pandemic, leads to increased stress and psychological issues like burnout. Peer Support Programs (PSP) are a recognized intervention for mitigating these issues. These programs are increasingly being delivered virtually through Peer Support Systems (PSS) for increased convenience and accessibility. However, HCWs' perception of these systems results in fear of information sharing, perceived lack of safety, and low participation rate, which challenges these systems' ability to achieve their goals. In line with the rich body of research on the requirements and properties of trustworthy systems, we posit that increasing HCWs' trust in PSS could address these challenges. However, extant research focuses on objectively defined trustworthiness rather than perceptual trust because trustworthy requirements are viewed as more controllable and easier to operationalize. This study proposes a novel approach to elicit perceptual trust requirements by proposing a trust framework anchored in recognized trust theories from different disciplines that unpacks trust into its recognized types and their antecedents. This approach allows the identification of trust requirements beyond those already proposed for trustworthy systems, providing a strong foundation for improving the effectiveness of PSS for HCWs.
