This study presents a unified model of information technology (IT) continuance, by drawing upon three alternative influences that are presumed to shape continuance behavior: reasoned action, experiential response, and habitual response. Using a longitudinal survey of workplace IT continuance among insurance agents at a large insurance company in Taiwan, we demonstrate that the above influences are interdependent, complementary, and have crossover effects. This study advances IT continuance research by theorizing and validating a unifying model that extends prior perspectives and by explaining interrelationships between these perspectives.

Little attention has been paid in previous literature to understanding the factors that drive online social support from a perspective of social psychology. This study validates a research model that examines the above issue. In the setting of information technology, this study postulates self-efficacy and online support expectancy as the key drivers of information technology usage, whereas information technology usage and referent network size jointly influence online social support. This study contributes to the social science literature by extending information technology usage models to the area of rarely explored online social support and by presenting an operationalization of referent network size in the area.
