Structural equation model of anticipated population behavioral change with HIV knowledge, NPEP Knowledge and covariates among Chinese MSM (n = 419). Note. * p < 0.05, ** p < 0.01, *** p < 0.001; Fit index: RMSEA = 0.012, 90% CI 0.000–0.021, CFI = 0.996, TLI = 0.995; HIV = HIV knowledge, Change = anticipated population behavioral change, NPEP = NPEP knowledge, Age = age, City = city of residence, Never married = never married, NPEP use = the use of NPEP, Internet = mainly looking for male sexual partners through the Internet. The full model estimated the relationships among anticipated population behavioral change (the outcome), HIV knowledge, NPEP knowledge, and all covariates, but only significant paths were shown in solid lines for simplicity. Dotted lines were the primary paths of interest but not statistically significant. All path coefficients shown were standardized. The oval represents a latent construct measured by multiple items which are not shown in the diagram for simplicity
