Empirical validation of a developmental model for binge-eating disorder in adolescents: a structural equation modeling approach

Table 2 Model fit indices of the examined models

Models	χ2(df)	CFI	TLI	RMSEA
A1. SEM of binge-eating symptomatology in girls	45.35(15)	0.980	0.963	0.060
A2. Same as A1, grouping by age (i.e., young teens and adolescents)	75.89(34)	0.972	0.955	0.066
A3. Same as A2, with parameters constrained to be equal between age groups	139.45(48)	0.940	0.930	0.083
A4. Same as A3, with some parameters allowed to vary between age groups¹	94.21(44)	0.9767	0.958	0.064
B1. SEM of binge-eating symptomatology in boys	13.03(15)	1.000	1.000	0.000
B2. Same as B1, grouping by age (i.e., young teens and adolescents)	45.72(36)	0.988	0.981	0.037
B3. Same as B2, with parameters constrained to be equal between age groups	77.33(50)	0.966	0.962	0.053
B4. Same as B3, with some parameters allowed to vary between age groups²	49.14(45)	0.995	0.994	0.022

¹ The parameters allowed to vary were the associations between (1) executive functioning and binge-eating symptomatology severity, and (2) reward sensitivity and binge-eating symptomatology severity
² The parameters allowed to vary were the associations between (1) executive functioning and binge-eating symptomatology severity, (2) reward sensitivity and binge-eating symptomatology severity, and (3) negative affectivity and binge-eating symptomatology severity
