Validating the Efficacy-Based Change Model

The purpose of this paper was to empirically validate the Efficacy-Based Ch ange Model as a theoretical model of change. The model suggests that as par ticipants are involved in an innovation, they move through stages of implem entation, in the process expressing different concerns that are related to the efficacy process and are further influenced by ascribed attributions. D ata analysis strongly supported the role of self-efficacy as it related to expressed concerns (those with higher effcacy expressed concerns associated with later stages). High efficacy was predicted by success attributions fo r effort; regression analysis for outcome expectation and value also yielde d significant models. (C) 1999 Elsevier Science Ltd.
