Previous research has primarily examined consumers’ perceived usefulness of web sites and trust in the web
retailer as two major predictors of web site use and e-commerce adoption. While the consumers’ repeated
behavior in the past (i.e., habit) may contribute to continuance behavior, it has not been investigated. This
article includes habit as a primary construct along with perceived usefulness and trust to predict and explain
consumers’ continued behavior of using a B2C web site. Additionally, included are several web quality
measures as antecedents to trust and perceived usefulness. The research model is evaluated using structural
equation modeling. Results show that consumers’ behavioral intentions to continue using a B2C web site are
determined by all three key drivers: perceived usefulness, trust, and habit. Furthermore, not all dimensions of
web quality have a significant effect on perceived usefulness and trust.
