Confirmatory factor analysis of measurement model (N = 205).

Model	χ 2	df	Δχ2 (Δdf) test	CFI	TLI	RMSEA	SRMR
Model 1	221.40	98	–	0.95	0.94	0.08	0.05
Model 2	466.45	101	p < 0.001	0.86	0.84	0.13	0.07
Model 3	759.27	101	p < 0.001	0.76	0.71	0.18	0.16
Model 4	1040.48	103	p < 0.001	0.65	0.59	0.21	0.13
Model 5	1561.81	104	p < 0.001	0.46	0.37	0.26	0.19

All comparisons are relative to Model 1. Model 1: Four factor model. Model 2: Three factor model–likeability and competence items load onto the same factor. Model 3: Three factor model–relational identification and family supportive supervisor behaviors items load onto the same factor. Model 4: Two factor model–likeability, competence, and relational identification items load onto the same factor. Model 5: All items load onto a single factor. CFI, comparative fit index; TLI, Tucker-Lewis index; RMSEA, root mean square error of approximation; SRMR, standardized root mean residual.
