Hi everyone!

Very thankful for this board as I am in big trouble finding out which analysis I should use. Let me shortly explain my study:

I showed 120 people each 8 facebook posts (screenshots) and had them rank it on a 5 point Likert scale on three IV, namely "Level of entertainment", "Level of information", "Level of emotional arousal", and one DV "Willingsness to Share".

I am pretty sure its a repeated measures within subjects design. However I am too confused to know which test to use.  I have thought about categorizing each IV as high/low (mean under 3 is low, and above 3 is high), and then perform a paired samples t-test for each IV variable. So I have two columns in SPSS, one with the share scores for the low and one for the high and then I compare the means? Is that possible to do this for each? I also have control variables, and I would have no idea how to include them in a paired t-test.

Secondly, I would also like to know which one influences the DV the most, and also interactions. My hypothesis are "The level of information in a brand posts is positively related to the number of shares". The only test that we use regularly is a normal multiple regression analysis. Is there any way for me to use it? Would make it so much easier...

Thank you soo much in advance!

Cheers,
