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.
