Reliability assessment of the attitude towards computers instrument (ATCI)

摘要

Individual's attitude towards computers is a key component to understanding user's acceptance and satisfaction with computer-based information systems. As such, individuals' attitudes towards computers have been of interest to researchers in a variety of settings for sometime. Therefore, numerous instruments have been developed to assess this construct. We describe these instruments and discuss issues for researchers to consider when selecting an instrument with which to assess attitude towards computers. We find few instruments that are suitable for a general setting or have had their reliability thoroughly assessed. We, therefore, present a reliability assessment of the Attitude Towards Computers Instrument (ATCI), which was designed to be applicable in a wide variety of settings. The reliability assessment includes latent structure (confirmatory factor) analysis, internal consistency (Cronbach's alpha) analysis and stability (test-retest) analysis. We find that the reliability of the ATCI compares favorably with existing instruments, making it a better choice for many research settings. Reliability analysis such as presented in this paper helps move the information systems field forward by providing researchers with a reliable instrument with which to assess attitude towards computers.
