This article is a theoretical analysis of the use of the Technology Acceptance Model (TAM) and synthetizes the results of twelve literature reviews and meta-analyses. We analyzed their content according to four thematic axes: the validity of the TAM, the evaluation of the role of each of its variables, the influence of external variables and moderators and the intellectual development of the TAM. The literature globally confirms the reliability of each of the variables in the TAM and the relevance of the relationships between these variables. However, weaknesses are noted and recommendations made for future research, such as the inclusion of more contextual information on the use of technologies and on participant characteristics and additional various measurement methods of use and its benefits. A notable difference has been identified in the relationship between the main variables of TAM and the objective and subjective measures of the actual use of technologies. In addition, objective measures of actual use have been included in few practical studies, but have generally included small samples, which impairs the strength of the results. Another weakness of the TAM is its significantly lower capacity to predict the volume (time of use over a given period), as well as the frequency of use (number of use over a given period) of a technology, compared to the simple prediction of use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
