The continuing growth and internationalization of e-commerce makes necessary the establishment of cross-cultural validity of theoretical concepts. A crucial concept in online commerce is consumer fear of online identity theft. Fear of online identity theft is said to hamper consumer willingness to transact online and thus can negatively affect e-commerce business. This emerging research cross-culturally assesses the original consumer fear of online identity theft scale and proposes an abbreviated version of the scale. Formal validation procedures with samples of online consumers from three major e-commerce markets (Germany, the U.S., and Japan) largely point to the reliability and cross-cultural validity of both the original and short scale. This research offers tentative implications for IS and e-commerce research as well as e-commerce managers.
