Confirmatory factor analysis and factorial invariance of the impact of information technology instrument

Organizations increasingly evaluate information technology in terms of its impact on the individual and his/her work. Academics have shown increased attention to developing measures of technology success in terms of impact on work. One of these efforts produced an instrument that measures how extensively information technology applications impact task productivity, task innovation, customer satisfaction, and management control. These constructs reflect perceived usefulness of information technology application for work. This paper reports on confirmatory analysis and factorial invariance tests of the impact of information technology instrument. The recommended four-factor instrument contains 12 items, seems to be factorially invariant across two samples from the US and Mexico and across two managerial levels, and has high reliability and validity.
