Hello Seren,

you conduct the multigroup analysis for this model as for any other model. As I don't use AMOS, I cannot tell you how but I am sure Gaskin (see youtube) has a video about that.

As the usual procedure in multigroup models you should

1) test the basic model with a chi-square test (and optimize)

2) test for metric invariance

3) and finally test the equivalence of the structural effects across the groups.

One further comment: As are lucky to have three waves, you probably may consider to run a random-intercept CLP model that gives you between-subjects and within-subjects estimates. Again I don't know who this is done in AMOS but perhaps the possibility motivates you to move forward (to R) and leave AMOS behind you :)

The Mund/Nestler paper is especially interesting as it provides access to the lavaan code in R.

All the best,

Dear Holger,

Thank you very much for detailed explanation. I feel already inferior that I do not have a grasp of R unfortunately.

Fröhliche Weihnachten!

Seren

Seren,

I guess you understand German? If yes, I have a handy introduction into SEM with lavaan:

And with regard to R, this could help

All the best,

Seren Gunes, learning R is an investment worth considering being a PhD student. As far as your question is concerned, you can benefit from the following book which includes a chapter on Latent Variable Models with Multiple Groups using R: https://www.routledge.com/Latent-Variable-Modeling-Using-R-A-Step-by-Step-Guide/Beaujean/p/book/9781848726994

Thank you both for the suggestions on R resources!

I am weeks aways from presenting my dissertation, so learning R would be a task of later times, hopefully :)

Best,

Seren
