Note. Model fit: χ²(73) = 111.46, CFI = 0.991, TLI  =   0.988, RMSEA =  0.042; 90% CI [0.025, 0.058], SRMR = 0.061. Residual correlations between the reversed items of Perceived infectability were included (Item 5 and Item 2: r = 0.45, p < 0.001; Item 12 and Item 14: r = 0.35, p < 0.001; Item 5 and Item 14: r = 0.38, p < 0.001).
