This paper is the second of two concerned with a meta‐analysis of the technology acceptance model (TAM). This part aims to present a rigorous and quantitative meta‐analytic review of 569 findings from 95 TAM studies as a basis for identifying gaps and providing guidelines for implementation management and conduct of future research. The paper also seeks to investigate the potential impact of methodological characteristics on the meta‐analytic findings.


The approach consists of meta‐analysis following Hedges and Olkin's procedures, moderator‐analysis using homogeneity Q‐values, analogue to ANOVA and weighted regression method.


The dominant focus in empirical investigations of the TAM has been on modelling intention for its effect on self‐reported usage behaviour, while the attitudinal construct has been neglected. This raises three questions: whether the exclusion of attitude from the TAM is beneficial for understanding of technology usage behaviour in mandatory settings; whether the revised TAM holds equally for mandatory and voluntary settings; and whether the emphasis on measuring intentions and self‐report use rather than actual usage is warranted. An additional question answered in the meta‐analysis is about the relative importance of PU and PEOU.


The paper provides a rigorous meta‐analysis to progress towards a unified view of the TAM.
