Sports Medicine - Open

Table 4 Comparisons of factor loadings and intercepts of the individual Exercise Addiction Inventory items in six samples from five different countries

Items	Test of equality of factor loadings				Test of equality of intercepts
Items	Δ χ ²	p -Value	ΔRMSEA	ΔCFI	Δ χ ²	p -Value	ΔRMSEA	ΔCFI
Exercise is the most important thing in my life (item 1)	13.0	<0.03	0.001	0.002	225.9	<0.001	0.027	0.063
Conflicts have arisen between me and my family and/or my partner about the amount of exercise (item 2)	13.7	<0.02	0.001	0.003	1,238.5	<0.001	0.069	0.292
I use exercise as a way of changing my mood (item 3)	34.9	<0.001	0.004	0.007	214.7	<0.001	0.005	0.061
Over time I have increased the amount of exercise I do in a day (item 4)	3.7	0.600	0.001	0.004	179.9	<0.001	0.017	0.247
If I have to miss an exercise session I feel moody and irritable (item 5)	15.7	<0.01	0.001	0.003	153.0	<0.001	0.001	0.042
If I cut down the amount of exercise I do, and then start again, I always end up exercising as often as I did before (item 6)	15.6	<0.01	0.001	0.003	140.8	<0.001	0.004	0.068

For the newly proposed decision criteria, to compare two-nested models the cut-off value of ΔCFI is ≤0.01 and the cut-off value for ΔRMSEA is ≤0.015 [27, 28].
Δχ ² Satorra–Bentler scaled (S–B scaled) χ ² difference test, ΔRMSEA the difference of root mean squared error of approximation values in two models compared, ΔCFI the difference of comparative fit index values in two models compared.
