Abstract
This essay examines validity and empirical relevance of successive kinds of access to technology model (SAT) as important segment of resources and appropriation theory (RAT). SAT model proposed by Van Dijk has been developed into a theoretical evolutionary frame, which seeks to explain the social unequal access to information and communications technologies (ICT). Methodological approach used in the study consists of a comparative approach supported by previous knowledge that helped determine statistical validity of assumptions that form basis of SAT model. Analyzed information comes from an extensive and representative source of microdata that was examined through modeling using structural equations. In this initial approximation, research confirms that SAT Model is characterized by a relative efficiency defined by significant causal relationships albeit low predictive power.
