An empirical study of computer self-efficacy and the technology acceptance model in the military: A case of a U.S. Navy combat information system

The U.S. Navy continues to be a major developer and procurer of information systems (ISs), yet very limited research has been done to determine the factors that influence technology acceptance by naval personnel. Literature suggests that efforts to embrace information technology in improving decision making and reducing workload depend heavily on the use of such systems. Moreover, previous research has shown the validity of the technology acceptance model (TAM) and computer self-efficacy (CSE) to model technology acceptance in numerous environments. However, very little research was done specifically addressing such technology acceptance with military combat ISs. Thus, this study examines the applicability of the extended TAM with a CSE construct model to the U.S. Navy’s combat ISs. A survey sample of 237 sailors from five different U.S. Navy aircraft carriers was used to assess such an extended model on a U.S. Navy’s combat IS. Results indicate that perceived ease of use, perceived usefulness, and CSE were valid antecedents of technology acceptance (as indicated by intention to use). Moreover, high Cronbach’s alpha was observed on all measures, indicating reliability of the measures in the context of military organizations
