A Systematic Validation of the Jian et al. (2000) “Trust in Automated Systems Scale”

The “Trust in Automated Systems Scale” by Jian et al. (2000) is one of the most commonly used scales to measure people's reported trust in the automated systems. While the original authors proposed trust and distrust as being on the opposite ends of the continuum on a single underlying factor, other researchers have shown that trust and distrust are two separate, yet related factors as a two-factor model showed a superior fit than a single-factor model (e.g., Perrig et al., 2023; Spain et al., 2008). However, previous validation studies did not evaluate the scale’s factor structure using a large sample size or the original unmodified scale. Thus, the current study aims to evaluate the factor structure of the Trust in Automated Systems Scale by conducting a confirmatory factor analysis using existing available datasets from a systematic search. We aim to compare if the two-factor model has a better fit than the one-factor model, and if modification (substituting the word “system”) influences the model fit of the scale.
