Comparison of hypothesized model with alternative models.
| Models | Description | χ2 (df) | RFI | RMSEA | NFI | CFI | Δ χ2 (df) |
|---|---|---|---|---|---|---|---|
| M1 (partial mediation) | WSP → CRH, POS, WE, EE; CRH → WE, EE; POS → WE, EE. | 66.66 (25) | 0.873 | 0.073 | 0.952 | 0.968 | .. |
| M2 (full mediation) | WSP → CRH, POS; CRH → WE, EE; POS → WE, EE. | 74.08 (27) | 0.869 | 0.075 | 0.947 | 0.964 | 7.42 (2)* |
| M3 (direct effects only) | WSP, CRH, POS → WE, EE | 202.41 (27) | 0.643 | 0.145 | 0.854 | 0.867 | 135.7 (2)*** |
Note: WSP = work safety practices, CRH = COVID risks/hazards, POS = perceived organizational support, WE = work engagement, EE = emotional exhaustion, RFI = relative fit index, RMSEA = root mean square error of approximation, NFI = normed fit index, CFI = comparative fit index. *p < .05, **p < .01, ***p < .001.
