Trust is a central construct and plays a critical role in understanding Internet consumer behavior. This research seeks to directly address the subject of Internet Commerce Trust (ICT) by developing a valid, reliable, and generalizable scale to measure this multifaceted subject. Two separate studies reveal a common five-factor structure. These dimensions are labeled (1) Certification, (2) Resources and Capabilities, (3) Shopping Method, (4) Reliability, and (5) Communication Viability. An accurate measurement of ICT will serve as a viable control factor in future studies of Internet consumer behaviors, segmentation analyses, and in marketing strategy research.
