The development of a psychometric instrument for human-computer trust: An Investigation of Trust Within the Context of Computer -Aided Decision -Making

The definition and measurement of human -computer trust (HCT) was addressed in this study in an exploration of trust as a general human experience and as an outcome of computer -aided decision -making. Trusting computer systems is an increasingly important issue for systems researchers, developers and users due to current market demands to provide and access information and business electronically and the trend toward automation through the use of intelligent systems. There has been little consistency to date in existing HCT research. Neither a robust definition of HCT nor a well -designed psychometric instrument for HCT could be found. This study, therefore, aimed to contribute to a better understanding of the nature and structure of HCT and to provide a carefully designed and tested instrument for the measurement of HCT within the context of computer -aided decision -making. The proposed theoretical model for HCT is based on social attribution theory and the theory of ethopoeia.
