From: How do we measure attention? Using factor analysis to establish construct validity of neuropsychological tests

	TLI	RMSEA (90% CI)	RMSR	BIC	SABIC
One factor	0.836	0.082 (0.071, 0.092)	0.064	− 194.227	50.053
Two factors	0.905	0.063 (0.049, 0.075)	0.046	− 224.492	− 21.454
Three factors	0.979	0.030 (0.000, 0.047)	0.030	− 238.140	− 73.172
Four factors	1.008	0.000 (0.000, 0.029)	0.022	− 204.908	− 74.837
Five factors	1.014	0.000 (0.000, 0.027)	0.017	− 157.549	− 59.203

A good fit is defined by TLI > 0.95, RMSR < 0.05, and RMSEA < 0.06 with lower value of CI close to 0 and upper value no more than 0.08
