Hospital Staff’s Adherence to Information Security Policy: A Quest for the Antecedents of Deterrence Variables

Information security has come to the forefront as an organizational priority since information systems are considered as some of the most important assets for achieving competitive advantages. Despite huge capital expenditures devoted to information security, the occurrence of security breaches is still very much on the rise. More studies are thus required to inform organizations with a better insight on how to adequately promote information security. To address this issue, this study investigates important factors influencing hospital staff’s adherence to Information Security Policy (ISP). Deterrence theory is adopted as the theoretical underpinning, in which punishment severity and punishment certainty are recognized as the most significant predictors of ISP adherence. Further, this study attempts to identify the antecedents of punishment severity and punishment certainty by drawing from upper echelon theory and well-acknowledged international standards of IS security practices. A survey approach was used to collect 299 valid responses from a large Taiwanese healthcare system, and hypotheses were tested by applying partial least squares-based structural equation modeling. Our empirical results show that Security Education, Training, and Awareness (SETA) programs, combined with internal auditing effectiveness are significant predictors of punishment severity and punishment certainty, while top management support is not. Further, punishment severity and punishment certainty are significant predictors of hospital staff’s ISP adherence intention. Our study highlights the importance of SETA programs and internal auditing for reinforcing hospital staff’s perceptions on punishment concerning ISP violation, hospitals can thus propose better internal strategies to improve their staff’s ISP compliance intention accordingly
