I'm working with a scale with negatively and positively worded items. The theory suggests that its factor solution should be unidimensional with correlated errors of the NW items.
The scale is a twelve version item. lets say var1 to var12. Also im using WLSMV.
How can I include in the Mplus model this by using CTCU?

thanks in advance,

Correlated errors are handled by WITH statements also for WLSMV.

Thanks for the answer Dr. Muthen.

I stated the correlated errors by using the WITH statement but it didīt work. The employed instruction is as follow
Factor by var1 var2 var3 var4 var5 var6 var7;
var1 WITH var2 var 1 WITH var3 and so on...

Is this the correct employment of the command?

You have to say:

var1 WITH var2; var 1 WITH var3; etc
