Psychometric Properties of the Chinese Version of Human-Computer Trust (HCT) Scale in the Chinese Sample of Adults

An appropriate human-computer trust (HCT) is a key element affecting the use of Intelligent Decision Aids (IDA). Through item-level analysis, exploratory factor analysis, and confirmatory factor analysis, this study showed that the revised version of the HCT consisting of two sub-factors cognitive-based trust (10 items) and affect-based trust (6 items) was a valid and reliable scale to assess human's trust towards computers in China, using two groups of samples with different occupation backgrounds in China. Moreover, variables trust in automation and interpersonal trust were used to examine HCT's criterion validity, both of which showed moderate to high significant correlations with each dimension of HCT. It was the first psychometric assessment and validity test of the HCT scale in different culture using a large-scale dataset and expected to provide both theoretical and practical values for future researchers.
