Model Fit Indices of the Confirmatory Analytic Sample.

	Model	WLSMV χ2	df	p value	TLI	CFI	RMSEA (90% CI)
1	Three factors (hypothesized)	207.69	51	<.001	0.916	0.935	0.092 [0.079, 0.105]
2	Two factors (“effort” item loaded on both factors)	123.37	52	<.001	0.962	0.970	0.061 [0.470, 0.075]
3	Two factors (“effort” item removed)a	165.58	43	<.001	0.967	0.974	0.065 [0.055, 0.076]

Note. CFI = comparative fit index; RMSEA= root-mean square error of approximation; TLI = Tucker–Lewis index; WLSMV= weighted least squares mean estimator.
