Prelim analysis with ANOVA? PreviousNext

I am planning on conducting a LGM with 4 waves of data. At this point I'm determining the feasibility of this, and someone mentioned that an ANOVA can be conducted in the first stage to give a crude look at whether time is relevant to my variables? I'm not familiar with this, therefore I'm not sure what this ANOVA would be? Any thoughts?

You can do a repeated measures ANOVA but I don't see any reason to do so. I would fit a LGM which is a more flexible model than repeated measures ANOVA.

I am interested in doing a simple repeated measures design with a categorical IV with 3 levels and a continuous DV measured at 2 time points. I'm interested in differences between the 3 groups over time, as in a RM ANOVA. Based on what I have read, it seems this would necessitate using a longitudinal modeling approach that treats the IV as a grouping variable. Since I am only interested in differences between groups rather than model comparisons, is there a simpler way to do this?
Thank you!

This is a good question for SEMNET.
