Predicting E-Services Adoption: A Perceived Risk Facets Perspective
Internet-delivered e-services are increasingly being made available to consumers; however, little is known about how consumers evaluate them for potential adoption. Past Technology Adoption Research has focused primarily on the positive utility gains attributable to system adoption. This research extends that approach to include measures of negative utility (potential losses) attributable to e-service adoption. Drawing from Perceived Risk Theory, specific risk facets were operationalized, integrated, and empirically tested within the Technology Acceptance Model resulting in a proposed e-services adoption model. Results indicated that e-services adoption is adversely affected primarily by performance-based risk perceptions, and perceived ease of use of the e-service reduced these risk concerns. Implications of integrating perceived risk into the proposed e-services adoption model are discussed.
Understanding the Internet banking adoption: A unified theory of acceptance and use of technology and perceived risk application
Understanding the main determinants of Internet banking adoption is important for banks and users; our understanding of the role of users' perceived risk in Internet banking adoption is limited. In response, we develop a conceptual model that combines unified theory of acceptance and use of technology (UTAUT) with perceived risk to explain behaviour intention and usage behaviour of Internet banking. To test the conceptual model we collected data from Portugal (249 valid cases). Our results support some relationships of UTAUT, such as performance expectancy, effort expectancy, and social influence, and also the role of risk as a stronger predictor of intention. To explain usage behaviour of Internet banking the most important factor is behavioural intention to use Internet banking.
