Note: GAD, generalized anxiety disorder; OCD, obsessive-compulsive disorder; PD, panic disorder; SA, separation anxiety disorder; SP, social phobia; df, degrees of freedom; #par, number of parameters; CFI, comparative fit index; TLI, Tucker–Lewis Index; RMSEA, root mean square error of approximation.

CFI decrease smaller than 0.005.
