Note. Models 2–5 are compared to Model 1. RMSEA = Root Mean Square Error of Approximation, SRMR = Standardized Root Mean Square Residual, CFI = Comparative Fit Index, TLI = Tucker-Lewis Index, GO = Government Trust, CO = Conspiracism, VA = Vaccination intention, ID= Identified motivation, DI = Distrust-based amotivation, EX = External motivation, EF = Effort-based amotivation. ***p < .001.
