Knowledge management (KM) research has yielded extensive theoretical explanations on the motivations of an individual to share knowledge using various types of face-to-face or virtual communication, each with different sets of influential factors. We propose that by decomposing individual belief into multidimensional belief constructs specific to knowledge contribution and knowledge-seeking contexts, those diverse factors can be consistently related to the antecedents of behavioral intention. Based on information systems (IS) continuance research and extant literature on KM, we formulate the research models for knowledge management systems (KMS) continuance for knowledge-contribution and -seeking behaviors, and test them with empirical data.
