I'm certainly stressing out in regards to my MSc Thesis right now and I could certainly use your help.

I am testing a IS success model. It consists of 9 constructs. I did a multiple regression analysis for all expected significant correlations (according to theory). The whole model and the regression analysis look like this:

However, after this went fine (according to my opinion) I now need to do a hierarchical regression analysis (i think, to see what the effect of the mediators are or something?). I haven't slept last night due to working on my thesis. I am starting to hallucinate. What does the following hierarchical regression table tell me about the full model?

Furthermore, did I test all 4 models using this method? I really need some help, so thanks in advance for even reading this!

Cheers,

A desperate student
