Goodness of fit indices for the measurement models of POC-M (initial and final models)

Model	CFI	TLI	SRMR	RMSEA (90% CI)	RMSEA (P-value)
Initial model	0.880	0.867	0.075	0.058 (0.054, 0.062)	< 0.001
Final modela	0.922	0.911	0.064	0.048 (0.044, 0.051)	0.847

Notes: CFI = Comparative fit index; TLI = Tucker-Lewis index; SRMR = standardised root mean square residual; RMSEA = root mean square error of approximation; CI = confidence interval

^aModel with correlated items’ residual and first order factors residual: PC7 with PC5, PC3 with PC1, PC5 with PC4, PC29 with PC17, PC18 with PC16, PC12 with PC2, PC8 with PC7; stimulus control with counter-conditioning, self-reevaluation with consciousness raising, stimulus control with social liberation and stimulus control with help relationships
