Measuring Perceived Usability in Chinese Questionnaires: mTAM, SUS, and UMUX

In this study, we explored usability structures in the Chinese environment by (i) developing a Chinese version of the modified Technology Acceptance Model (mTAM), which uses a strict translation and prediction test process with strict psychometric evaluation characteristics and (ii) examining the relationships among Chinese versions of mTAM, SUS, and UMUX; we find that the three questionnaires have a strong correspondence. Further verification revealed that the correlation between SUS and PEU is stronger than between SUS and PU. Though the three questionnaires were developed independently in the Chinese environment, all can be used to effectively measure perceived usability.
