Fit indices of measurement model, structural model, and model comparison (N = 1071)

Model	χ² (df)	χ²/df	RMSEA	SRMR	CFI	TLI	Satorra-Bentler scaled ∆χ²
1. Measurement model	2777.65 (960)	2.89	.044	.045	.913	.906
2. Full mediation model	2868.87 (967)	2.97	.046	.052	.909	.902
3. Partial mediation model	2862.86 (964)	2.97	.046	.052	.909	.902	1 vs. 2 ∆χ² (3) = 6.66

Note. The partial mediation model includes direct effects from received social support from the school principal on the satisfaction of all three basic needs. All models are estimated with the robust maximum likelihood estimator; RMSEA = root mean square error of approximation; SRMR = standardised root mean square residual; CFI = comparative fit index; TLI = Tucker–Lewis index.
