Table 2.

Model fit indices for the hypothesized and nested structural equation models.

Model	CFI	TLI	RMSEA	90% CI RMSEA	SRMR	AIC
Hypothesized model	0.891	0.874	0.079	[0.074, 0.087]	0.095	22,251.54
Nested model	0.928	0.916	0.068	[0.061, 0.074]	0.050	22,644.481

The nested model excluded the non-significant structural path from mentalization ability (RFQ_lat) to substance-related risk behavior (WHO_lat); CFI = comparative fit index; TLI = Tucker–Lewis index; RMSEA = root mean square error of approximation; SRMR = standardized root mean square residual.
