Developing and evaluating a reliable measure of user engagement



Increased emphasis on user experiences with technology demonstrates that systems must be not only usable, but engaging. Engagement, defined as a quality of user experience, is a multidimensional construct characterized by aesthetic appeal, novelty, perceived challenge, feedback and control, attention, motivation, and affect. To measure engagement, we developed a multidimensional instrument and surveyed 440 online shoppers to assess its reliability and construct validity. Results of exploratory factor analysis showed that engagement is comprised of six distinct factors: perceived usability, aesthetics, focused attention, involvement, novelty, and endurability.
