Table 2. Global fit indices of confirmatory factor analysis.

	N	χ 2	df	p	χ 2/df	TLI	CFI	RMSEA	RMSEA 90% CI	SRMR
Original CFA model a	172	477.94	149	< .001	3.21	0.88	0.90	0.11	0.10–0.13	0.04
Modified CFA model b	172	398.84	146	< .001	2.73	0.91	0.92	0.10	0.09–0.11	0.04

Notes:

^a Though EFA-(PCA) analysis suggested a one-factor solution, we performed an original CFA with the three latent variables “psychological, physical, social”.

^b As modification indices suggested that model fit would be improved if correlated error terms were included, we added three theoretically plausible correlated error terms.

Abbreviations: CFI: comparative fit index, CI: confidence interval, df: degrees of freedom, RMSEA: root mean square error of approximation, SRMR: standardized root mean square residual, TLI: Tucker–Lewis index.
