Model 1	72.48*	20	3.62	.765	.671	.104	120.48	.508

Model 3	53.41	19	2.81	.846	.773	.087	103.41	.534

Notes: Model 1 is a one-factor model with no correlations between items. Model 2 is a one-factor model with correlations between items 3 and 8 as well as items 6 and 7. Model 3 is a two-factor model with factor 1 including items 1 to 5 and 8 and factor 2 including item 6 and 7. All models were calculated for the whole data set (n = 242)
