Hello,
I have a question about comparing a path model from pre-intervention to a post-intervention situation. The goal is to determine if there is a change in the variables over time.
I think you could compare the estimates prior to the intervention and after the intervention to determine the change (if any) in the relationships between variables and the overall R square of the model.
Would a multigroup analysis work - use the same group twice?
Also, can you point me toward any manuscripts that have conducted this type of analysis.
I would appreciate any advice you all might have.
I have attached the model
Sincerely,
Art Bangert

Re: Pretest and posttest modeling
Thanks. Comparison of PLS results across different points of time is a super interesting research topic since almost no suggestions exist on that topic. In your specific situation, your approach sounds plausible for a start.

Re: Pretest and posttest modeling
A potential problem with a multi-group analysis could be that all current test assume independent samples, but you have dependent samples.
An easier way to analyze pre- and post-test measures would be to use difference scores.

Thank you , Dr. Becker,
That does make sense to me.
Thanks for the suggestion
