Promoting Patient Portals: An Application of Social Cognitive Theory to Post-Adoption Patient Portal Use.

Many healthcare clinics encourage the use of online patient portals so that patients can have easier access to their health information, yet some patients are hesitant to interact with these portals. We used social cognitive theory to develop and test a theoretically grounded model that incorporates several (1) technological factors, (2) individual factors, and (3) social factors that influence individuals' post-adoption, active use of patient portals. Based on cross-sectional survey data from a sample of healthcare clinic patients (N = 431), we found that individuals' severity of illness predicted active use of patient portals and that trust in doctors predicted attitudes toward patient portals. Moreover, attitudes toward patient portals mediated the relationship between technology factors (i.e., perceived usefulness, ease of use, customization, and interactivity), and active use of patient portals. The paper concludes with a discussion of key findings, implications, and directions for future research.
