TABLE 2.

Results of the confirmatory factory analysis with three different models, across n = 124 participants.

Model	Chi-square/df ratio	CFI	SRMR	WRMR	RMSEA (90% CI)
1-factor	3.18	0.976**	0.90*	1.058	0.133 (0.108–0.158)
2-factor	1.43**	0.995**	0.055*	0.603**	0.059* (0.017–0.090)
2-factor plus total score	7.15	0.932*	0.147	1.837	0.224 (0.201–0.247)

The symbol ** indicates good model fit according to Schermelleh-Engel et al. (2003) and DiStefano et al. (2018).

The symbol * indicates acceptable model fit according to Schermelleh-Engel et al. (2003) and DiStefano et al. (2018).

df, degrees of freedom; CFI, comparative fit index; SRMR, standardized root mean squared error; WRMR, weighted root mean squared error; RMSEA, root mean square error of approximation.
