Model Fit and χ² Difference Tests for One-Factor, Two-Factor, and Three-Factor Models

	χ²	p value	CFI	TLI	RMSEA
Four-factor
Baseline	62.025	.002	.979	.986	.062
Two-factor
Factor 1: SEFC, SEVC
Factor 2: PEFV-P, PEFV-S	165.874	.000	.898	.917	.152
One-factor	396.215	.000	.727	.751	.264
Uncorrelated four-factor	283.479	.000	.805	.759	.260

NOTE: All χ² values for difference testing are statistically significant (ps < .001), indicating that the two-factor, one-factor, and uncorrelated four-factor mode l constraints significantly degrade the fit of the correlated three-factor model. CFI = comparative fit index; TLI = Tucker–Lewis index; RMSEA = root mean square error of approximation; SEFC = self-efficacy for fruit consumption; SEVC = self-efficacy for vegetable consumption; PEFV-P = proxy efficacy from parents; PEFV-S = proxy efficacy from after-school staff.
