Measurement invariance of the Yale Food Addiction Scale 2.0 (YFAS 2.0) and modified YFAS 2.0 (mYFAS 2.0) across sex.

	Configural model	Loadings constrained as equal	Loadings and thresholds constrained as equal
YFAS 2.0 Modified first-order structure
X 2(df) or ΔX 2(Δdf)	227.64 (84)	25.25 (10)	20.23 (10)
CFI or ΔCFI	0.997	–0.009	0.000
YFAS 2.0 Modified second-order structure
X 2(df) or ΔX 2(Δdf)	232.19 (84)	418.05 (10)	24.7 (10)
CFI or ΔCFI	0.989	0.004	0.005
mYFAS 2.0 Modified first-order structure
X 2(df) or ΔX 2(Δdf)	3055.61 (1092)	37.48 (35)	27.72 (23)
CFI or ΔCFI	0.966	0.000	0.001

CFI, comparative fit index, and ΔCFI > –0.01 indicates measurement invariance.
