I have 11 items loading on 1 factor, and I want to detect measurement bias by including an interaction with a dichotomous variable (say gender). Is this the correct way to do this:

TITLE: SEM
DATA: FILE IS 13042011.dat;
VARIABLE: NAMES ARE y1-y11 gender;
ANALYSIS: TYPE = RANDOM;
ALGORITHM = INTEGRATION;
MODEL: f1 BY y1*-y11;
f1 @1;
gender @.5;
f1 with gender;
[f1 @ 0];
[gender @0];
f1xgender | f1 XWITH gender;
y1 ON f1xgender;
OUTPUT: TECH1 TECH8;

I have copied this from example 5.13 in the manual, but I am not sure this is applicable to my situation (i.e. a dichotomous interaction).

Thank you very much!

The last two lines are correct. I am not clear of the motivation for:

gender @.5;
f1 with gender;
[gender @0];
