Now I am struggling a bit on how to best analyze these data. In SPSS I tried GLM -> repeated measures with 3 factors (prime, consistency, perspective) with the 2 levels each and the anxiety, avoidance values as covariates. There where some significant outcomes, but I am not sure if I can trust that method?

I know that a Multi-level approach is also possible but with that I have absolutely no clue how to do that right and also how to interpret the outcomes correctly.

I really would appreciate your help! If necessary I can also upload my SPSS data and the syntax of what I have done so far.
