Chi-square difference test: a Δχ2 (1) = 6.926, p < 0.01 (H3a—supported), b Δχ2 (1) = 0.065, p > 0.05 (H3c—not supported). Goodness-of-fit statistics for the baseline model: χ2 = 1578.288, df = 670, p < 0.001, χ2/df = 2.254, RMSEA = 0.067, CFI = 0.905, IFI = 0.906, NFI = 0.843, TLI = 0.893. Note 1: PP = perceived performance, ATT = attitude. Note 2: ** p< 0.001. Note1. RMSEA = root mean square error of approximation, CFI = comparative fit index, IFI = incremental fit index, NFI = normed fit index, TLI = Tucker–Lewis index.
