Meta-Analysis of TAM

From Information Systems at Pitt Business

The Technology Acceptance Model (TAM) was developed many years ago and has become one of the most prevalent models in IS research. This study performs a meta-analysis of 88 TAM studies and also reviews the usage of TAM in IS and other disciplines. The authors found that TAM has expanded to other disciplines outside of IS, and that the overall model is the best statistical model to explain user intentions and behaviors in regards to technology usage.

[edit] Abstract

A statistical meta-analysis of the technology acceptance model (TAM) as applied in various fields was conducted using 88 published studies that provided sufficient data to be credible. The results show TAM to be a valid and robust model that has been widely used, but which potentially has wider applicability. A moderator analysis involving user types and usage types was performed to investigate conditions under which TAM may have different effects. The study confirmed the value of using students as surrogates for professionals in some TAM studies, and perhaps more generally. It also revealed the power of meta-analysis as a rigorous alternative to qualitative and narrative literature review methods.
