Table 1. The ratios of the CSI with the NEO-FFI resulting from the HTMT method.

Measure	1	2	3	4	5	6
1. CSI	-
1. Neuroticism	0.32	-
2. Extraversion	0.4	0.36	-
3. Openness	0.43	0.29	0.4	-
4. Agreeableness	0.39	0.37	0.5	0.32	-
5. Conscientiousness	0.58	0.32	0.26	0.29	0.31	-

The proposed cut-off value is .85 [47], with higher ratios indicating insufficient discriminant validity.
