This cross-sectional survey of 460 Chinese consumers used structural equation modeling to compare a modified Theory of Planned Behavior model (M-TPB) with the original TPB model for predicting continuous organic food purchase intentions in the post-COVID-19 era. The M-TPB model, which incorporated Chinese cultural constructs, health consciousness, perceived value of organic food, and impact of COVID-19, explained 65% of variance compared to 40% for the original TPB model.
