Does the technology acceptance model predict actual use? A systematic literature review

Context The technology acceptance model (TAM) was proposed in 1989 as a means of predicting technology usage However. it is usually validated by using a measure of behavioural intention to use (131) rather than actual usage Objective This review examines the evidence that the TAM predicts actual usage using both subjective and objective measures of actual usage Method We performed a systematic literature review based on a search of six digital libraries, along with vote-counting meta-analysis to analyse the overall results Results The search identified 79 relevant empirical studies in 73 articles The results show that HI is likely to be correlated with actual usage However, the TAM variables perceived ease of use (PEU) and perceived usefulness (PU) are less likely to be correlated with actual usage Conclusion Care should be taken using the TAM outside the context in which it has been validated (C) 2009 Elsevier B V All rights reserved
