While research in general has extensively studied the coherence between attitude and behavior, Information Systems (IS) research has paid little attention to the antecedents of attitude. Using the elaboration likelihood model (ELM) as theoretical basis, we focus on the factors that determine attitudes in IS research. We apply a meta-analytic structural equation model based on major IS-adoption models that focuses on classifying the antecedents of attitude in the studies of our meta-analysis according to the central and peripheral route of information processing proposed by the ELM. The results indicate that affect and cognition as representatives for the central route are less important as attitudinal antecedents in the IS context compared to external factors that represent the peripheral route of information processing.
