Hi,
I'm just embarking on my analysis using Mplus. I have many scales that are reverse scored. Can you please advise whether Mplus will reverse the scoring of specified scales (7-point likert) or will I have to do it manually?

Mplus does not reverse scores. You would need to use the DEFINE command to do this.

Hello!
One of my models needed to add two reverse indicators.
Trying to follow one of your posts, i used this syntax:
"DEFINE:
SBPN13r=8-SPBN13r;
SPBN19r=8-SPBN19r;"

However, warning message do not recognise one of the reverse indicators. ex:
"ERROR
Undefined variable used in transformation: SPBN13R".

Thank you for your attention,

Note that you have a different name on the LHS and RHS:

SBPN13r=8-SPBN13r;

Yes!...they seemed the same...thanks!

Meanwhile MPlus do not know were to find the new variables..but i already wrote them after the previous ones in the "variable" command + in the "use variable" and defined the syntax for reverse indicators...
SBPN13r=8-SBPN13r;
SPBN19r=8-SBPN19r;
Nonetheless:
"*** ERROR in DEFINE command
Error in assignment statement for MISSING."

Thank you!
