Note. Insignificant factor loadings (p > .05) are underscored. Factor loadings > .50 are in boldface. CFI = comparative fit index; RMSEA = root mean squared error of approximation; SRMR = standardized root mean squared residual. Model fit is considered adequate by meeting the following criteria: CFI ≥ 0.95, RMSEA ≤ 0.08, SRMR ≤ 0.08. The three-factor solution is not reported, because standard errors could not be computed due to model identification issues.
