Dear Muthen,

I have three time-points, and try to figure out how to test for intercept invariance across time.

My model is:

model:
TASK1 by thz201T1(1)
thz202T1(2)
thz208T1(3)
thz212T1(4);
BOND1 by thz203B1(5)
thz205B1(6)
thz207B1(7)
thz209B1(8);
GOAL1 by thz206G1(9)
thz210G1(10)
thz211G1(11);

[thz201T1@0]; [thz203B1@0];[thz206G1@0];

[TASK1*];[BOND1*];[GOAL1*];

for each group and then

[thz202T1 thz202T2 thz202T3] (12)
[thz208T1 thz208T2 thz208T3] (13)
[thz212T1 thz212T2 thz212T3] (14);

for each factor

Is this the right syntax for testing intercept invariance across time?
I have the feeling something is not right...

Thank you!

Please see the Topic 4 course handout under multiple indicator growth. All of the inputs for testing measurement invariance across time are shown there.
