*To perform the multiple-group analysis for a moderator variable (consumer trust towards Thai street food safety), two subsamples were created: a low consumer trust (Low CT) group and a high consumer trust (High CT) group. In order to build the subgroups, the summed scores of the latent variable, consumer trust, were calculated. Seven items were added up (Cronbach’s alpha, or, CA = 0.955). Next, consumer trust (CT) was weighted by the frequency of street food consumption (mean = 6.569, SD = 3.796). The subsamples (high and low for the CT construct) were created based on the median (4.500) of CTWeighted by frequency to split the groups. High CT (median > 4.500) = 220 samples and High CT (median ≤ 4.500) = 204 samples
