Fit statistics for the confirmatory factor analysis.

Comparative fit index (CFI)	Normed fit index (NFI)	Standardized root mean square residual (SRMR)	Root mean square error of approximation (RMSEA)
0.920	0.908	0.064	0.101 (90% CI: 0.092, 0.110)

CFI: a value greater than or equal to 0.90 indicates a good fit (Hu and Bentler, 1999).

NFI: a value greater than or equal to 0.90 indicates a good fit (Hu and Bentler, 1999).

SRMR: a value less than or equal to 0.08 indicates a good fit (Hu and Bentler, 1999).

RMSEA: a value less than or equal to 0.08, or a CI that encompass this value, indicates a good fit (Jaccard and Wan, 1996).
