Model	CFI1	TLI1	RSMSA2
Unidimensional (all 10 items)	.970	.981	.068
8-item scale (items 1&2 removed)	.985	.989	.058
Two-dimensional3	.974	.984	.063

Notes.

¹CFI/TLI > .9 indicates reasonably good fit (Kline, 2005; pp. 137-141)

²RSMEA between 0.05 and 0.08 suggests reasonable fit (Kline, 2005; pp. 137-141)

³Two dimensional model; items 1 and 2 loaded on one factor, and items 3 to 10 on the other factor; factors were correlated.
