Model 1: three-factor model	M, C, and E were each a first-order factor	57.598	24	.989	.056	.027
Model 2: two-factor model	All M and C items were combined to load onto a first-order factor. E was another first-order factor	390.988	26	.879	.178	.061	333.39	2	< .01
Model 3: single-factor model	All items load onto a single factor	1250.645	27	.593	.320	.184	1193.05	3	< .01
